INTRODUCTION

Urinary bladder is an extremely rare site of extrapulmonary small cell cancer (EPSCC). Unlike small cell lung cancer (SCLC), there is no clear guideline for prophylactic cranial irradiation (PCI) for EPSCC. In this case report and literature review, we discuss small cell cancer of urinary bladder (SCCUB) and the role of PCI in SCCUB.

CASE PRESENTATION

A 74-year-old male presented with gross hematuria and an unremarkable physical examination. CT showed 1.7 cm right anterolateral bladder wall thickening. Cystoscopy revealed a 2-3 cm high-grade bladder lesion. Pathology from transurethral resection of the tumor was consistent with T1N0M0 small cell carcinoma. MRI brain and FDG-PET showed no extravesical disease. Patient received four cycles of neoadjuvant carboplatin/etoposide per his preference as he wanted to protect his hearing due to his profession followed by radical cystoprostatectomy. Post-op pathology showed clear margins. We decided to forego PCI in favor of interval surveillance with MRI and follow- up images remain negative for distant metastases.

DISCUSSION

EPSCC accounts for 2.5-5% of all SCC, very rare in male genitourinary tract. Treatment approach is derived from SCLC, guided by extent of disease and patient’s functional status. Role of PCI in EPSCC has not been clearly described, and even less evidence is available for SCCUB. From a review of eleven studies in PubMed for the role of PCI in SCCUB or EPSCC, we found that SCCUB has lower incidence of brain metastases than SCLC. One study suggested that SCCUB arises from totipotent cells in the submucosa, unlike Kulchitsky cell origin of SCLC. This difference might explain the difference in their metastatic behavior. With this background, PCI is not routinely recommended for limited- stage SCCUB. There might still be a role for PCI in extensive SCCUB with high metastatic burden. More studies are needed to update the guidelines for the role of PCI for these tumors.

CONCLUSIONS

Per this literature review, PCI is not routinely recommended for SCCUB, likely due to different cells of origin compared to SCLC. Future studies should focus on characterizing differences in their metastatic behavior and updating guidelines for PCI for SCCUB.

Two shave biopsies were taken, 1 in the center of a previous SCC site with hyperkeratosis, the other in a site not previously affected by SCC but with the physical features of a pustule. Biopsy results from both sites were consistent with erosive pustular dermatosis, an unusual inflammatory disorder that mimics SCC.

Erosive pustular dermatosis of the scalp is an uncommon dermatitis that usually affects older women but may appear in men and women of all ages. It can mimic many other conditions that can affect the scalp, including seborrheic dermatitis, psoriasis, actinic keratosis, and SCC.

The exact causative mechanism is not understood, and cases may develop spontaneously. Rough papules, pustules, crusts, and ulcers develop and (apart from the pustules) share many features of actinic keratoses, SCCs, and field cancerization. The presence of pustules helps point to the diagnosis.

Triggers include previous surgery or physical trauma, burns, skin or hair grafts, and treatment of actinic keratoses with imiquimod, 5-fluourouracil, or photodynamic therapy. Some autoimmune diseases (including Hashimoto thyroiditis, autoimmune hepatitis, and rheumatoid arthritis) have been linked to disease occurrence and severity.¹

Treatment includes potent or super-potent topical steroids such as clobetasol 0.05% ointment. Topical tacrolimus 0.1% ointment and calcipotriene 0.005% cream have been reported as steroid alternatives. Paradoxically, photodynamic therapy, while associated with triggering disease, has also been used therapeutically. Systemic immunomodulators such as cyclosporine 3 mg/kg/d or prednisone 0.5 to 1 mg/kg/d may be needed in severe cases. Antibiotics including topical dapsone 5% gel, systemic dapsone from 50 mg bid to tid, and doxycycline have been helpful due, in part, to their immunomodulatory effects.^1,2

This patient was told to apply topical triamcinolone 0.1% ointment around and over ulcers and pustules and to take doxycycline 100 mg twice daily. The patient cleared well after 6 weeks. He continued to apply topical triamcinolone every few days as maintenance therapy.

He had some mild recurrence after discontinuing all topical and oral therapy, so he currently is being maintained on topical clobetasol 0.05% ointment every other day. He comes in for follow-up appointments every 3 months to monitor for control of the erosive pustular dermatosis of the scalp and for skin cancer surveillance.

INTRODUCTION

Lymphadenopathy in Chronic Lymphocytic Leukemia (CLL) is a very common feature. However, sudden increase in lymphadenopathy or other symptoms like weight loss should be evaluated for possible metastatic malignancy. We describe a CLL patient with diffuse mediastinal lymphadenopathy who was diagnosed with metastatic bladder cancer without a primary bladder tumor mass on imaging.

CASE DESCRIPTION

A 60-year-old man with a 60 pack-year smoking history, alcoholic cirrhosis, and a 5-year history of stage 1 CLL presented with 3 months of progressive shortness of breath; persistent cough; chills; hemoptysis; and a steady weight loss of 35 lbs. Notably, he had no bladder symptoms. Initial labs showed leukocytosis of 35.8k with a lymphocytic predominance. Screening low-dose chest CT was positive for diffuse mediastinal lymphadenopathy. Subsequent PET/CT revealed numerous hypermetabolic lymph nodes in the neck, mediastinum, left hilum, and right periaortic abdominal region. CT Chest, Abdomen, Pelvis revealed progressive lymphadenopathy as seen in prior imaging, stable pulmonary nodules up to 4 mm in size, and splenomegaly. No distant primary sites, including of the bladder, were identified. Mediastinal lymph node biopsy confirmed metastatic poorly differentiated carcinoma with immunohistochemical staining negative for p40, p63, CK20, TTF-1, Napsin A, CDX2, CA19- 9, Calretinin, and D2-40 and positive for CK7, GATA3, Ber-EP4, and Uroplakin, supporting bladder as primary origin. Urology deferred a cystoscopy given his lack of urinary symptoms and positive biopsy and was started on Carboplatin/Gemcitabine for his metastatic disease. He was ineligible for Cisplatin given his cirrhosis and hearing impairment.

DISCUSSION

In patients with CLL, new onset mediastinal lymphadenopathy is concerning for disease progression and possible transformation to a diffuse b-cell lymphoma. However, this symptom has a broad differential, including primary lung carcinomas, sarcomas, and metastatic disease. While our patient’s PET/CT and pan-CT failed to identify a distant primary site, maintaining a low clinical suspicion for metastatic disease and doing a thorough work-up was paramount. Only through immunohistochemical staining were we able to diagnosis this patient with urothelial carcinoma.

CONCLUSIONS

Biopsy with immunohistochemical staining and maintaining a low suspicion for worsening lymphadenopathy can identify unusually presenting urothelial carcinomas in CLL patients.

Throughout the 20th century, the management of ectopic pregnancy evolved from preserving the life of the mother to preserving fertility by utilizing the conservative treatment of methotrexate and/or tubal surgery. I make this, seemingly obscure, reference to managing ectopic pregnancy to consider an analogous shift over time in the management of patients with cancer. Over the next decade, the number of people who have lived 5 or more years after their cancer diagnosis is projected to increase approximately 30%, to 16.3 million. Due to the improved survival rates following a cancer diagnosis,¹ revolutionary developments have been made in fertility preservation to obviate the impact of gonadotoxic therapy. We have evolved, however, from shielding and transposing ovaries to ovarian tissue cryopreservation,² with rapid implementation.

While advances in reproductive cryopreservation have allowed for the delay, or even potential “prevention” of infertility, assisted reproductive technology (ART) cannot yet claim a “cure” in ensuring procreation. Nevertheless, fertility preservation is a burgeoning field that has transitioned from an experimental label to a standard of care in 2012, as designated by the American Society for Reproductive Medicine (ASRM).³ From the original intention of offering oocyte cryopreservation to women at risk of ovarian failure from impending gonadotoxic cancer treatment, fertility preservation has accelerated to include freezing for nonmedical reasons—eg, planned oocyte cryopreservation (POC), or “social” egg freezing, to ovarian tissue cryopreservation to accommodate the expediency needed for the treatment of certain cancer treatments. Additionally, across the United States, the number of donor egg banks, which allow women an easily accessible option, is rivaling enduring sperm banks. Due to the advanced methodology of vitrification and growing demand for the technology due to increasing IVF cycles, cryopreservation has become a specialized area of reproductive medicine, and a target of venture capital and private equity commercialization. This article will review the latest techniques, appropriate counseling, and cost/benefit ratio of fertility preservation, with an emphasis on POC.

CASE 1 Fertility preservation options for patient with breast cancer

A 37-year-old woman with newly diagnosed hormone receptor−positive breast cancer is referred for a fertility preservation consultation prior to initiating treatment. Her oncologist plans chemotherapy, followed by radiation and a minimum of 5 years of tamoxifen therapy.

What is the best consultation approach for this patient?

Consultation involves understanding several factors

The consultation approach to this patient involves ascertaining her medical, social, and family history, along with her reproductive plans.

Medical history. For the medical component, we must focus on her diagnosis, anticipated treatment with timeline, risks of gonadal toxicity with planned treatments, her current medical stability, and prognosis for expected survival.

Social history. Her age, relationship status, and desired family size address her social history.

Family history. Given that her cancer affects the breast, there is the risk of genetic susceptibility and potential for embryo testing for the BRCA gene.

Reproductive plans. These include her and her partner’s, if applicable, number of desired children and their risk factors for infertility.

Regarding the reproductive timeline, the antihormonal therapy that may be required for her treatment may improve overall survival, but it would delay the time to pregnancy. Consequently, the pursuit of fertility preservation prior to cancer treatment is a multidisciplinary approach that can involve medical oncology, radiation oncology, REI, medical genetics, and often, psychology. Fortunately, evidence continues to support fertility preservation, with or without hormonal ovarian stimulation, for patients with breast cancer. Data, with up to 5 years of follow-up, has indicated that it is safe.⁴

Oncofertility

To address the need to maximize the reproductive potential of patients with newly diagnosed cancer, the field of oncofertility combines the specialties of oncology and reproductive medicine. The reproductive risk of cancer treatment is gonadotoxicity, with subsequent iatrogenic primary ovarian insufficiency (POI) and infertility. Alkylating agents (including cyclosphosphamide) have the highest risk for amenorrhea, while antimetabolites (including methotrexate, 5–fluorouracil) have the lowest risk.⁵ Treating bone marrow/stem cell transplantation using high-dose alkylating agents, with or without whole body irradiation, results in ≥80% amenorrhea. The minimum radiation dose to induce ovarian failure decreases with advancing age, from 18.4 Gy at age 10 years to 6 Gy at age 40 years, due to biologically diminishing ovarian reserve and an increase in the radiosensitivity of oocytes.⁶ An online tool—using varying factors including age, chemotherapy dose, prior treatment, smoking, and baseline diminished ovarian reserve—is available to help predict the chance of ovarian failure following chemotherapy.⁷

Cryopreservation to the rescue

Since 2012, when ASRM removed the experimental designation on oocyte cryopreservation (OC), the number of cycles offered for fertility preservation has increased dramatically (FIGURE),⁸ initially being used for patients with cancer and now also including women desiring POC.

OC followed by thawing for subsequent fertilization and embryo transfer is employed as a matter of routine when patients with infertility utilize frozen eggs from a donor. While there remains debate over better live birth rates with frozen eggs versus fresh eggs, clinic experience may be a critical factor.¹⁰

Ovarian tissue cryopreservation. In addition to the fertility preservation procedures of oocytes and embryo cryopreservation, ovarian tissue cryopreservation became a standard option in 2019 when ASRM removed its experimental designation.¹¹ Given the potential time constraints of urgent cancer treatment, ovarian tissue cryopreservation has the advantage of not requiring ovarian stimulation or sexual maturity and is able to be performed while patients are receiving chemotherapy. If successful, ovarian tissue cryopreservation followed by orthotopic transplantation has the potential to restore natural ovarian function and natural conceptions.¹² However, despite first successfully being described in 2004, ovarian tissue cryopreservation, which does require subsequent thawing and tissue transplantation, remains less available to patients due to low usage rates, which have resulted in few clinics having adequate proficiency.^13,14

Ovarian tissue cryopreservation involves obtaining ovarian cortical tissue, dissecting the tissue into small fragments, and cryopreserving it using either a slow-cool technique or vitrification. Orthotopic transplantation has been the most successful method for using ovarian tissue in humans. Live birth rates are modest.¹⁵ In all cancer survivors, particularly those with leukemia, autologous ovarian tissue transplantation may contain malignant cells that could lead to the reintroduction of cancer as the tissue is removed prior to treatment.¹⁶

Pregnancy outcomes using embryos created from ovaries recently exposed to chemotherapy in humans is not known, but animal studies suggest that there may be higher rates of miscarriage and birth defects given the severe DNA damage to oocytes of developing follicles.¹⁷ Hence, ovarian stimulation should be initiated and completed before the start of chemotherapy.

Continue to: Planned oocyte cryopreservation...

Planned oocyte cryopreservation

With advances in ART, POC offers patients the opportunity to preserve fertility until desired. However, despite its potential benefits, POC compels the discussion of various considerations in addition to oncofertility, such as ethical concerns and insurance coverage.

CASE 2 Woman plans for elective egg freezing

A 32-year-old single, professional woman is advancing in her career and wishes to delay childbearing. She is concerned about the potential for age-related fertility decline and wants to explore the option of elective egg freezing. Emily has no medical conditions that would impair her fertility, but she wants to ensure that she has the option of having biological children in the future. She is unsure about the potential financial burden of the procedure and whether her employer’s insurance covers such elective procedures.

How do you counsel her about her options?

Medical considerations

Approximately 25% of reproductive-aged women have considered POC.¹⁸ An analysis revealed POC was more cost-effective than delaying procreation and undergoing IVF with preimplantation genetic testing for aneuploidies at an advanced reproductive age.¹⁹

The process of planned oocyte cryopreservation. POC involves ovarian stimulation, usually with parenteral gonadotropins, to produce multiple mature oocytes for same-day cryopreservation following transvaginal retrieval, typically in an office-based surgery center as an outpatient procedure while the patient is under IV sedation. While the procedure has been proven effective, there are inherent risks and limitations. The success rates of subsequent fertility treatments using the cryopreserved eggs are influenced by the woman’s age at the time of freezing, the number of mature oocytes retrieved and vitrified, and the quality of the oocytes following thaw. A recent study reported a 70% live-birth rate in women aged less than 38 years who cryopreserved ≥ 20 mature eggs.²⁰ To increase the number of cryopreserved oocytes, multiple egg retrievals or “batching” may be of benefit for women with diminished ovarian reserve.²¹

It is important for clinicians to thoroughly assess a patient’s medical history, ovarian reserve (by antral follicle count and levels of anti-müllerian hormone [AMH]), and reproductive goals before recommending proceeding with POC. Of note, AMH is a useful marker for ovarian reserve but has not been shown to predict natural fertility. Its value is in providing a guide to the dosage of ovarian stimulation and an estimation of the number of oocytes to be retrieved. Per ASRM, “Extremely low AMH values should not be used to refuse treatment in IVF.” AMH levels and antral follicle count have only a weak association with such qualitative outcomes as oocyte quality, clinical pregnancy rates, and live birth rates. Complications from egg retrieval, both short and long term, are rare. The inherent risk from POC is the lack of a guaranteed subsequent live birth.²²

Ethical and social considerations

POC raises several ethical considerations, including concerns of perpetuating societal pressure on women to defer procreation to prioritize their careers over family planning.²³ Despite controversies, POC appears as a chosen strategy against age-related infertility and may allow women to feel that they are more socially, psychologically, and financially stable before pursuing motherhood.²⁴ Open and honest discussions between clinicians and patients are crucial to ensure informed decision making and address these ethical concerns.

Per an ACOG statement from February 2023 (https://www.acog.org/womens-health/faqs/having-a-baby-after-age-35-how-aging-affects-fertility-and-pregnancy) “...egg freezing is recommended mainly for patients having cancer treatment that will affect their future fertility. There is not enough research to recommend routine egg freezing for the sole purpose of delaying childbearing.”

A recent survey of patients who had elected egg freezing at some point included more than 80% who were aged 35 or older, and revealed that 93% of the survey participants had not yet returned to use their frozen oocytes.²⁵ The most common reason cited in the survey for a delay in attempted procreation was lack of a partner. Another reason was undergoing oocyte cryopreservation after an optimal reproductive age, with participants concluding that they felt they had improved their reproductive future after undergoing oocyte cryopreservation and feeling empowered by the process. As part of counseling, women should be informed of the possibility of not utilizing their frozen eggs in the future, whether due to natural conception or other personal reasons.

Employer insurance coverage

Access to elective egg freezing is largely influenced by insurance coverage. Currently, employer-provided insurance coverage for this procedure varies widely. While some companies offer comprehensive coverage, others provide limited or no coverage at all. The cost of elective egg freezing can range from $10,000 to $15,000, excluding additional expenses such as medications and annual storage fees. The financial burden can create a gap between patients who desire POC and those with an ability to implement the process. The cost can be a significant barrier for many patients considering this option and perpetuates the lack of universal diversity, equity, and inclusion.

CASE 3 Gender dysphoria and fertility preservation

A 22-year-old transgender man is preparing to undergo gender-affirming hormone therapy and surgery. He is concerned about the potential impact of testosterone therapy on his oocytes and wishes to explore options for fertility preservation prior to oophorectomy.²⁶

What are the patient’s options for fertility preservation?

The patient has the fertility preservation options of OC following ovarian stimulation or ovarian tissue cryopreservation at the time of oophorectomy. Preliminary evidence does not demonstrate impairment of ovarian stimulation and oocyte retrieval number with concurrent testosterone exposure. Ethical considerations, in this case, involve respecting the patient’s autonomy, addressing potential conflicts between gender-affirming care and fertility preservation (eg, a risk of dysphoria in transgender patients preserving biological gametes from a prior assigned gender), and ensuring access to fertility preservation services without discrimination. It is essential to provide the patient in this case with comprehensive information regarding the impact of hormone therapy on fertility, the available options, and the potential financial costs involved. Supportive counseling should also be offered to address any psychological or emotional aspects related to fertility preservation for all patients considering this option.

A call for diversity, equity, and inclusion

To improve access to POC, advocating for employer-offered insurance coverage is paramount. Women’s health providers can encourage dialogue between employers, insurers, and policymakers, which can lead to policy changes that prioritize coverage for fertilitypreservation options. This could include mandating coverage for POC as part of comprehensive health care plans or providing tax incentives to employers who offer coverage for these procedures. Furthermore, public awareness campaigns and advocacy efforts can help educate employers about the importance of including fertility preservation coverage in their employee benefits packages.

Conclusion

Just as physicians must recognize their responsibility to patients to distinguish unproven yet promising science from evidence-based and clinically established science, so too must they advise their patients to consider fertility preservation services in a way that is both clinically justified and ethically appropriate. Informed decisions must be made by appropriate counseling of evidence-based medicine to protect the interest of patients. POC provides patients with an opportunity to preserve their fertility and exercise reproductive autonomy. However, access to this procedure is often hindered by limited or nonexistent employer insurance coverage. By recognizing the medical, ethical, and social implications of POC and implementing strategies to improve coverage, collaborative efforts may increase accessibility and defray costs to provide patients with the option of deferring childbearing and preserving their reproductive potential. ●

Throughout the 20th century, the management of ectopic pregnancy evolved from preserving the life of the mother to preserving fertility by utilizing the conservative treatment of methotrexate and/or tubal surgery. I make this, seemingly obscure, reference to managing ectopic pregnancy to consider an analogous shift over time in the management of patients with cancer. Over the next decade, the number of people who have lived 5 or more years after their cancer diagnosis is projected to increase approximately 30%, to 16.3 million. Due to the improved survival rates following a cancer diagnosis,¹ revolutionary developments have been made in fertility preservation to obviate the impact of gonadotoxic therapy. We have evolved, however, from shielding and transposing ovaries to ovarian tissue cryopreservation,² with rapid implementation.

While advances in reproductive cryopreservation have allowed for the delay, or even potential “prevention” of infertility, assisted reproductive technology (ART) cannot yet claim a “cure” in ensuring procreation. Nevertheless, fertility preservation is a burgeoning field that has transitioned from an experimental label to a standard of care in 2012, as designated by the American Society for Reproductive Medicine (ASRM).³ From the original intention of offering oocyte cryopreservation to women at risk of ovarian failure from impending gonadotoxic cancer treatment, fertility preservation has accelerated to include freezing for nonmedical reasons—eg, planned oocyte cryopreservation (POC), or “social” egg freezing, to ovarian tissue cryopreservation to accommodate the expediency needed for the treatment of certain cancer treatments. Additionally, across the United States, the number of donor egg banks, which allow women an easily accessible option, is rivaling enduring sperm banks. Due to the advanced methodology of vitrification and growing demand for the technology due to increasing IVF cycles, cryopreservation has become a specialized area of reproductive medicine, and a target of venture capital and private equity commercialization. This article will review the latest techniques, appropriate counseling, and cost/benefit ratio of fertility preservation, with an emphasis on POC.

CASE 1 Fertility preservation options for patient with breast cancer

A 37-year-old woman with newly diagnosed hormone receptor−positive breast cancer is referred for a fertility preservation consultation prior to initiating treatment. Her oncologist plans chemotherapy, followed by radiation and a minimum of 5 years of tamoxifen therapy.

What is the best consultation approach for this patient?

Consultation involves understanding several factors

The consultation approach to this patient involves ascertaining her medical, social, and family history, along with her reproductive plans.

Medical history. For the medical component, we must focus on her diagnosis, anticipated treatment with timeline, risks of gonadal toxicity with planned treatments, her current medical stability, and prognosis for expected survival.

Social history. Her age, relationship status, and desired family size address her social history.

Family history. Given that her cancer affects the breast, there is the risk of genetic susceptibility and potential for embryo testing for the BRCA gene.

Reproductive plans. These include her and her partner’s, if applicable, number of desired children and their risk factors for infertility.

Regarding the reproductive timeline, the antihormonal therapy that may be required for her treatment may improve overall survival, but it would delay the time to pregnancy. Consequently, the pursuit of fertility preservation prior to cancer treatment is a multidisciplinary approach that can involve medical oncology, radiation oncology, REI, medical genetics, and often, psychology. Fortunately, evidence continues to support fertility preservation, with or without hormonal ovarian stimulation, for patients with breast cancer. Data, with up to 5 years of follow-up, has indicated that it is safe.⁴

Oncofertility

To address the need to maximize the reproductive potential of patients with newly diagnosed cancer, the field of oncofertility combines the specialties of oncology and reproductive medicine. The reproductive risk of cancer treatment is gonadotoxicity, with subsequent iatrogenic primary ovarian insufficiency (POI) and infertility. Alkylating agents (including cyclosphosphamide) have the highest risk for amenorrhea, while antimetabolites (including methotrexate, 5–fluorouracil) have the lowest risk.⁵ Treating bone marrow/stem cell transplantation using high-dose alkylating agents, with or without whole body irradiation, results in ≥80% amenorrhea. The minimum radiation dose to induce ovarian failure decreases with advancing age, from 18.4 Gy at age 10 years to 6 Gy at age 40 years, due to biologically diminishing ovarian reserve and an increase in the radiosensitivity of oocytes.⁶ An online tool—using varying factors including age, chemotherapy dose, prior treatment, smoking, and baseline diminished ovarian reserve—is available to help predict the chance of ovarian failure following chemotherapy.⁷

Cryopreservation to the rescue

Since 2012, when ASRM removed the experimental designation on oocyte cryopreservation (OC), the number of cycles offered for fertility preservation has increased dramatically (FIGURE),⁸ initially being used for patients with cancer and now also including women desiring POC.

OC followed by thawing for subsequent fertilization and embryo transfer is employed as a matter of routine when patients with infertility utilize frozen eggs from a donor. While there remains debate over better live birth rates with frozen eggs versus fresh eggs, clinic experience may be a critical factor.¹⁰

Ovarian tissue cryopreservation. In addition to the fertility preservation procedures of oocytes and embryo cryopreservation, ovarian tissue cryopreservation became a standard option in 2019 when ASRM removed its experimental designation.¹¹ Given the potential time constraints of urgent cancer treatment, ovarian tissue cryopreservation has the advantage of not requiring ovarian stimulation or sexual maturity and is able to be performed while patients are receiving chemotherapy. If successful, ovarian tissue cryopreservation followed by orthotopic transplantation has the potential to restore natural ovarian function and natural conceptions.¹² However, despite first successfully being described in 2004, ovarian tissue cryopreservation, which does require subsequent thawing and tissue transplantation, remains less available to patients due to low usage rates, which have resulted in few clinics having adequate proficiency.^13,14

Ovarian tissue cryopreservation involves obtaining ovarian cortical tissue, dissecting the tissue into small fragments, and cryopreserving it using either a slow-cool technique or vitrification. Orthotopic transplantation has been the most successful method for using ovarian tissue in humans. Live birth rates are modest.¹⁵ In all cancer survivors, particularly those with leukemia, autologous ovarian tissue transplantation may contain malignant cells that could lead to the reintroduction of cancer as the tissue is removed prior to treatment.¹⁶

Pregnancy outcomes using embryos created from ovaries recently exposed to chemotherapy in humans is not known, but animal studies suggest that there may be higher rates of miscarriage and birth defects given the severe DNA damage to oocytes of developing follicles.¹⁷ Hence, ovarian stimulation should be initiated and completed before the start of chemotherapy.

Planned oocyte cryopreservation

With advances in ART, POC offers patients the opportunity to preserve fertility until desired. However, despite its potential benefits, POC compels the discussion of various considerations in addition to oncofertility, such as ethical concerns and insurance coverage.

CASE 2 Woman plans for elective egg freezing

A 32-year-old single, professional woman is advancing in her career and wishes to delay childbearing. She is concerned about the potential for age-related fertility decline and wants to explore the option of elective egg freezing. Emily has no medical conditions that would impair her fertility, but she wants to ensure that she has the option of having biological children in the future. She is unsure about the potential financial burden of the procedure and whether her employer’s insurance covers such elective procedures.

How do you counsel her about her options?

Medical considerations

Approximately 25% of reproductive-aged women have considered POC.¹⁸ An analysis revealed POC was more cost-effective than delaying procreation and undergoing IVF with preimplantation genetic testing for aneuploidies at an advanced reproductive age.¹⁹

The process of planned oocyte cryopreservation. POC involves ovarian stimulation, usually with parenteral gonadotropins, to produce multiple mature oocytes for same-day cryopreservation following transvaginal retrieval, typically in an office-based surgery center as an outpatient procedure while the patient is under IV sedation. While the procedure has been proven effective, there are inherent risks and limitations. The success rates of subsequent fertility treatments using the cryopreserved eggs are influenced by the woman’s age at the time of freezing, the number of mature oocytes retrieved and vitrified, and the quality of the oocytes following thaw. A recent study reported a 70% live-birth rate in women aged less than 38 years who cryopreserved ≥ 20 mature eggs.²⁰ To increase the number of cryopreserved oocytes, multiple egg retrievals or “batching” may be of benefit for women with diminished ovarian reserve.²¹

It is important for clinicians to thoroughly assess a patient’s medical history, ovarian reserve (by antral follicle count and levels of anti-müllerian hormone [AMH]), and reproductive goals before recommending proceeding with POC. Of note, AMH is a useful marker for ovarian reserve but has not been shown to predict natural fertility. Its value is in providing a guide to the dosage of ovarian stimulation and an estimation of the number of oocytes to be retrieved. Per ASRM, “Extremely low AMH values should not be used to refuse treatment in IVF.” AMH levels and antral follicle count have only a weak association with such qualitative outcomes as oocyte quality, clinical pregnancy rates, and live birth rates. Complications from egg retrieval, both short and long term, are rare. The inherent risk from POC is the lack of a guaranteed subsequent live birth.²²

Ethical and social considerations

POC raises several ethical considerations, including concerns of perpetuating societal pressure on women to defer procreation to prioritize their careers over family planning.²³ Despite controversies, POC appears as a chosen strategy against age-related infertility and may allow women to feel that they are more socially, psychologically, and financially stable before pursuing motherhood.²⁴ Open and honest discussions between clinicians and patients are crucial to ensure informed decision making and address these ethical concerns.

Per an ACOG statement from February 2023 (https://www.acog.org/womens-health/faqs/having-a-baby-after-age-35-how-aging-affects-fertility-and-pregnancy) “...egg freezing is recommended mainly for patients having cancer treatment that will affect their future fertility.

This could include mandating coverage for POC as part of comprehensive health care plans or providing tax incentives to employers who offer coverage for these procedures. Furthermore, public awareness campaigns and advocacy efforts can help educate employers about the importance of including fertility preservation coverage in their employee benefits packages.

This friable vascular papule was most consistent with a lobular capillary hemangioma (LCH), also called a pyogenic granuloma. A shave biopsy was performed at the base of the tumor to confirm the diagnosis and rule out malignant pedunculated tumors, including nodular melanoma, angiosarcoma, and metastatic carcinoma.

LCHs are benign vascular growths that occur on the skin and mucosa, most often in children and young adults. Growth may occur rapidly over days to weeks and tumors may grow to several centimeters in size. Although LCHs are often painless, they do tend to bleed easily with minor trauma.

While the triggering mechanism is unknown, LCHs have been associated with infection, trauma, hormonal factors (especially in the second and third trimesters of pregnancy), and therapy with retinoids. About 5% of pregnancies are associated with the development of an LCH on the oral mucosa, usually in the second or third trimester.¹

Treatment of LCHs is based on small case series and case reports. Individual tumors have a high likelihood of recurrence after a single treatment, so multiple visits for treatment are often recommended. Electrocautery is safe and effective with complete cure occurring after 2 sessions. Similarly, cryotherapy is safe and effective with excellent results after 3 treatment sessions. Cryotherapy may cause depigmentation in patients with darker skin types, so this should be discussed with patients with skin of color. Excision of small lesions is also safe and effective in a single session.²

This patient was treated with light electrodessication and curettage in 2 sessions with complete clearance.

A shave biopsy was performed at the base of the tumor to confirm the diagnosis and rule out malignant pedunculated tumors, including nodular melanoma, angiosarcoma, and metastatic carcinoma.

LCHs are benign vascular growths that occur on the skin and mucosa, most often in children and young adults. Growth may occur rapidly over days to weeks and tumors may grow to several centimeters in size. Although LCHs are often painless, they do tend to bleed easily with minor trauma.

While the triggering mechanism is unknown, LCHs have been associated with infection, trauma, hormonal factors (especially in the second and third trimesters of pregnancy), and therapy with retinoids. About 5% of pregnancies are associated with the development of an LCH on the oral mucosa, usually in the second or third trimester.¹

Treatment of LCHs is based on small case series and case reports. Individual tumors have a high likelihood of recurrence after a single treatment, so multiple visits for treatment are often recommended. Electrocautery is safe and effective with complete cure occurring after 2 sessions. Similarly, cryotherapy is safe and effective with excellent results after 3 treatment sessions. Cryotherapy may cause depigmentation in patients with darker skin types, so this should be discussed with patients with skin of color. Excision of small lesions is also safe and effective in a single session.²

This patient was treated with light electrodessication and curettage in 2 sessions with complete clearance.

The calcitonin gene-related peptide (CGRP) antagonist class of medications has changed the face of migraine treatment — and there are now both acute and preventive options that are available in oral and injectable formulations. The gepant subclass of CGRP antagonists are small-molecule medications, in contrast to the CGRP monoclonal antibodies. Atogepant was developed as the first oral migraine-specific preventive medication, and the initial trials allowed for an initial approval by the US Food and Drug Administration for episodic migraine alone. The study by Pozo-Rosich and colleagues extended the patient population to patients with chronic migraine.

This was an international, multicenter, randomized controlled study of two dosages of atogepant (30 mg twice daily and 60 mg daily) compared with placebo over 12 weeks. The primary endpoint was change in mean monthly migraine days. There was a safety population as well that received a single dose of medication. Nearly 800 participants were enrolled equally into these three groups, and the authors used a modified intention-to-treat format that included all participants with at least 1 month of e-diary data and took at least one dose of the study medication.

The baseline number of mean monthly migraine days in this chronic migraine population was 18.6 days per month. After 12 weeks, the three groups showed decreases of 7.5, 6.1, and 5.1 days per month, which was statistically significant for the two intervention groups. The most common side effects were constipation and nausea, with up to 10% of the study population experiencing some gastrointestinal symptoms. Weight loss of 7% of body weight was also noticed in the two intervention groups.

This study describes the benefit of atogepant extending beyond the indication of episodic migraine. This chronic migraine population showed significant benefit in the decrease of mean monthly migraine days per month after 12 weeks. One additional benefit is weight loss even after 12 weeks. Compared with the monoclonal antibody class of CGRP antagonist, this medication appears to be approximately equally effective, with the additional benefit of weight loss. Because many preventive medications for migraine may be associated with weight gain — particularly the antidepressant and potentially the antihypertensive classes of medications — this can be a differentiating factor when choosing an appropriate preventive medication for your patients with chronic migraine.

CGRP is a known inflammatory modulator that also plays a significant role in the propagation of migraine. CGRP blockade has been associated, in some studies, with upper respiratory tract infection symptoms, raising the question of whether blocking CGRP chronically may increase the risk for infection. A prior study revealed that CGRP levels were decreased in patients with severe COVID-19, and another study did not find significant differences in COVID-19 disease, progression, or severity among migraine patients on CGRP antagonists. Wang and colleagues specifically sought to determine any potential association or risk between the use of CGRP antagonist medications and COVID.

This retrospective cohort study was performed in the US Veterans Affairs (VA) hospital system. It analyzed the electronic medical records of veterans diagnosed with migraine between January and May 2022. The participants' exposure to CGRP medications and the 30-day odds of hospitalization, as well as use of mechanical ventilation, were calculated. CGRP prescriptions were identified using outpatient pharmacy records for erenumab, fremanezumab (225 mg/1.5 mL), and galcanezumab (120 mg/mL), which were the only CGRP medications available at that point in the VA system. The primary outcome was cumulative incidence of SARS-CoV-2 infection; occurrences of SARS-CoV-2 infection were obtained from the VA COVID-19 Shared Data Resource. Secondary analysis of the clinical outcomes was performed among patients with a positive SARS-CoV-2 test result.

This analysis revealed that CGRP monoclonal antibody use was not associated with risk for COVID-19, and among participants who tested positive for COVID-19, there were no significant differences in hospitalization, oxygen supplementation, mechanical ventilation, or COVID-19–related death between those who were receiving CGRP medications and those who were not. Although another prior study implied that CGRP blockade may decrease the risk for severe disease related to a cytokine storm, those results were only in vitro, and no results from human or animal trials have replicated these data. There is, therefore, no contraindication to using CGRP antagonist medications in people at high risk for development of COVID-19.

Many patients with migraine are recommended specific treatments for the prevention of migraine attacks and for the acute treatment of their attacks. Very few studies have investigated specific combinations of acute and preventive treatments. Although logically, there should be no contraindication to most treatment combinations, there may be some additional synergistic benefit to the combination of specific classes of medications. We have previously discussed a synergy between the CGRP antagonist class and onabotulinumtoxinA (Botox) for the prevention of chronic migraine; Manack Adams and colleagues sought to quantify the efficacy of ubrogepant when the patients were also administered botulinum toxin.

The joint American Academy of Neurology/American Headache Society consensus statement recommends starting preventive medication for anyone with migraine who experiences > 4-5 days of headache per month. It also recommends a migraine-specific acute treatment for anyone who experiences migraine attacks. Botulinum toxin is approved by the US Food and Drug Administration for the prevention of chronic migraine at a dose of 155 units injected every 3 months; ubrogepant is a CGRP oral small-molecule antagonist that is approved for the acute treatment of migraine.

This study investigated the effectiveness of ubrogepant, with a primary endpoint of meaningful pain relief and return to normal function 2 and 4 hours after an initial dose of 50 or 100 mg. Meaningful pain relief was defined as answering "yes" to a question about whether the patient experienced meaningful pain relief. This has been a pre-reported endpoint in other acute migraine treatment trials. Return to normal function was defined as the time point where the patient could perform their daily activities on the basis of a functional disability scale. Achieving normal function was classified as either remaining free of disability or by reporting functional disability before taking ubrogepant and then indicating a return to normal function at 2 and 4 hours post-dose.

A total of 134 patients were enrolled, taking both ubrogepant and botulinum toxin; patients were included if they were treated with ubrogepant at least once. Meaningful pain relief was achieved in 53.3% of patients at 2 hours and in 76.2% of patients at 4 hours post-dose. Return to normal function was achieved by 30.1% of patients at 2 hours and by 52.1% of patients at 4 hours post-dose. Both meaningful pain relief and return to normal function were seen to be statistically significant and stable across up to 10 attacks per person.

Headache treatment providers typically need to consider different classes of medications for prevention and acute treatment. A growing body of evidence describes a synergy between the CGRP class of medications and botulinum toxin. This appears to be true both when CGRP antagonists are used preventively and, in this case, when they are used for acute events. This certainly would be a safe and effective choice in many instances for many patients.

The Diagnosis: Infantile Transient Smooth Muscle Contraction of the Skin

A diagnosis of infantile transient smooth muscle contraction of the skin (ITSMC) was made based on our patient’s clinical presentation and eliminating the diagnoses in the differential. No treatment ultimately was indicated, as episodes became less frequent over time.

The term infantile transient smooth muscle contraction of the skin was first proposed in 2013 by Torrelo et al,¹ who described 9 newborns with episodic skin rippling occasionally associated with exposure to cold or friction. The authors postulated that ITSMC was the result of a transient contraction of the arrector pili smooth muscle fibers of the skin, secondary to autonomic immaturity, primitive reflexes, or smooth muscle hypersensitivity.¹ Since this first description, ITSMC has remained a rarely reported and poorly understood phenomenon with rare identified cases in the literature.^2,3 Clinical history and examination of infants with intermittent transient skin rippling help to distinguish ITSMC from other diagnoses without the need for biopsy, which is particularly undesirable in the pediatric population.

Congenital smooth muscle hamartoma is a benign proliferation of mature smooth muscle that also can arise from the arrector pili muscles.⁴ In contrast to ITSMC, a hamartoma does not clear; rather, it persists and grows proportionally with the child and is associated with overlying hyperpigmentation and hypertrichosis. The transient nature of ITSMC may be worrisome for mastocytoma; however, this condition presents as erythematous, yellow, red, or brown macules, papules, plaques, or nodules with a positive Darier sign.⁵ Although the differential diagnosis includes the shagreen patch characteristic of tuberous sclerosis, this irregular plaque typically is located on the lower back with overlying peau d’orange skin changes, and our patient lacked other features indicative of this condition.⁶ Becker nevus also remains a consideration in patients with rippled skin, but this entity typically becomes more notable at puberty and is associated with hyperpigmentation and hypertrichosis and is a type of smooth muscle hamartoma.⁴

Our case highlighted the unusual presentation of ITSMC, a condition that can easily go unrecognized, leading to unnecessary referrals and concern. Familiarity with this benign diagnosis is essential to inform prognosis and guide management.

THE CASE

A 24-year-old woman with a history of type 1 diabetes, seizure disorder, and migraines presented to a rural Federally Qualified Health Center (FQHC) with progressive and severe symmetric large joint arthralgias of several weeks’ duration. The patient’s existing medications included etonogestrel 68 mg subdermal implant, levetiracetam 1500 mg bid, insulin glargine 26 units subcutaneously nightly, and insulin lispro 20 units subcutaneously tid (before meals).

An examination revealed symmetrically edematous elbows, wrists, and fingers. Subsequent serologic analyses and a telemedicine consultation with a rheumatologist confirmed a diagnosis of rheumatoid arthritis (RA). The patient’s lab work was positive for antinuclear antibody titers (1:40), rheumatoid factor (513 IU/mL), and anticyclic citrullinated peptide antibodies (248 units/mL). Treatment was started with prednisone 60 mg PO daily, methotrexate 20 mg PO weekly, and hydroxychloroquine 400 mg PO daily. (The benefits of prednisone in treating this patient’s severe arthralgias outweighed concerns over its use in a patient with diabetes.)

After 2 months of receiving RA therapy, the patient underwent further work-up to assess its effectiveness. Liver function testing was performed, and she tested positive for hepatitis C virus (HCV) antibodies. Viral polymerase chain reaction confirmed active HCV infection. Lab work revealed a viral load of 15,000,000 IU/mL; transaminase, 173 U/L (normal range, 4-36 U/L); and aspartate aminotransferase, 246 U/L (normal range, 8-33 U/L). A liver sonogram demonstrated no findings of cirrhosis or fibrosis.

Upon receiving a diagnosis of active hepatitis C, the patient acknowledged that she’d had unprotected heterosexual intercourse and shared used insulin syringes with friends.

THE DIAGNOSIS

Consideration was given to a diagnosis of HCV arthropathy, which can present as an RA-like arthritis in HCV-infected individuals, in the differential diagnosis.¹ A cohort study found HCV-associated arthropathy occurred in 6.8% of those with chronic HCV infection.²

However, the symmetrical involvement of shoulders and knees as the patient’s primary arthralgias, and a rheumatologic work-up showing the presence of anticyclic citrullinated peptide antibody levels, confirmed the diagnosis of RA with coexisting HCV.

DISCUSSION

Delivering interdisciplinary care in a rural area

Although evidence-based guidelines and online HCV Treatment Path programs guided the initial evaluation of potential treatments for this patient, her multiple comorbidities prompted us to seek out additional, interdisciplinary advice through a resource for underserved communities called Project Extension for Community Healthcare Outcomes (ECHO; see “What is Project ECHO?^3,4”). The patient’s case was presented virtually, without identifying information, to a multidisciplinary HCV team. Two treatment options were suggested:

• sofosbuvir/velpatasvir (400 mg/100 mg) for 12 weeks or
• glecaprevir/pibrentasvir (100 mg/40 mg) for 8 weeks.

Both are evidence-based and recommended treatment options according to the HCV treatment guidelines issued jointly by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America.⁵

In most patients with HCV, treatment is guided by a number of factors, including pill burden, access to care, duration of therapy, drug interactions, and patient-specific needs. After analyzing all aspects of this patient’s case, 2 major concerns guided our shared decision-making process on treatment.

The best treatment is what works for the patient

Owing to the patient’s multiple comorbidities and prescribed medications for chronic diseases, concerns about possible medication interactions with the HCV treatment options were a factor in her HCV treatment plan. Additionally, the patient had significant social determinants of health barriers that made continued treatment and follow-up challenging.

The potential interaction of HCV infection treatment with the patient’s current methotrexate therapy for her RA was a primary concern. To determine the risk for interactions, the team used the University of Liverpool HEP/HIV Drug Interactions Checker, which helps identify possible interactions with these disease-specific medication therapies.⁶

Both sofosbuvir/velpatasvir and glecaprevir/­pibrentasvir have a potential interaction with methotrexate and are driven by a similar mechanism. Methotrexate is a substrate of the Breast Cancer Resistance Protein efflux transporter (BCRP), and the components of both sofosbuvir/velpatasvir and glecaprevir/pibrentasvir are inhibitors of BCRP.⁷ The inhibition of this efflux transporter can lead to an increased concentration of methotrexate, increasing the risk for methotrexate toxicity.⁷

Since no quantitative data exist regarding the degree of inhibition that these HCV drugs exert on BCRP, the team considered ­sofosbuvir/velpatasvir and glecaprevir/­pibrentasvir to have equal risk with regard to potential for drug interactions.

The patient’s barriers to treatment were another area of concern that directed our therapy decision. The patient had multiple barriers, including poor access to health care because of transportation issues, multiple children requiring care, a variety of chronic diseases, and other life stressors. Shared decision­-making ensured our patient’s autonomy in choosing a specific treatment.

This case shines a light on the multiple challenges that could have come between our patient and proper treatment—but ultimately, did not.

The patient’s social situation and preference narrowed the team’s basis for medication choice primarily down to the duration of therapy: 8 weeks of glecaprevir/pibrentasvir vs 12 weeks of sofosbuvir/velpatasvir. The patient mentioned multiple transportation challenges for follow-up visits to the clinic and therefore wanted to utilize the shorter treatment duration. Follow-up is needed every 4 weeks, so the patient was able to go from 3 to 2 visits.

For problems, there are solutions. Following careful consideration of these patient-specific factors and preferences, the team decided to begin therapy with glecaprevir/pibrentasvir. The patient worked with an outreach specialist at the FQHC to coordinate care and complete paperwork for the Project ECHO consultation. The outreach specialist also assisted the patient in completing paperwork for the Patient Assistance Program for HCV treatment. Because the patient is being cared for at an FQHC, the clinic’s in-house pharmacy was able to utilize the 340B Federal Drug Pricing Program, which makes otherwise out-of-reach medicines affordable for patients such as ours.

Our patient has had no issues with treatment adherence, adverse effects, or follow­-up appointments. The patient’s RA symptoms have improved significantly without any discernable worsening of her HCV infection.

THE TAKEAWAY

This case shines a light on the multiple challenges (clinical, geographic, and financial) that could have come between our patient and proper treatment—but ultimately, did not. The Project ECHO model of care remains a viable way to provide patients who live in rural and underserved communities and who have active HCV and other underlying chronic conditions with interdisciplinary care that can improve health outcomes.

THE CASE

A 24-year-old woman with a history of type 1 diabetes, seizure disorder, and migraines presented to a rural Federally Qualified Health Center (FQHC) with progressive and severe symmetric large joint arthralgias of several weeks’ duration. The patient’s existing medications included etonogestrel 68 mg subdermal implant, levetiracetam 1500 mg bid, insulin glargine 26 units subcutaneously nightly, and insulin lispro 20 units subcutaneously tid (before meals).

An examination revealed symmetrically edematous elbows, wrists, and fingers. Subsequent serologic analyses and a telemedicine consultation with a rheumatologist confirmed a diagnosis of rheumatoid arthritis (RA). The patient’s lab work was positive for antinuclear antibody titers (1:40), rheumatoid factor (513 IU/mL), and anticyclic citrullinated peptide antibodies (248 units/mL). Treatment was started with prednisone 60 mg PO daily, methotrexate 20 mg PO weekly, and hydroxychloroquine 400 mg PO daily. (The benefits of prednisone in treating this patient’s severe arthralgias outweighed concerns over its use in a patient with diabetes.)

After 2 months of receiving RA therapy, the patient underwent further work-up to assess its effectiveness. Liver function testing was performed, and she tested positive for hepatitis C virus (HCV) antibodies. Viral polymerase chain reaction confirmed active HCV infection. Lab work revealed a viral load of 15,000,000 IU/mL; transaminase, 173 U/L (normal range, 4-36 U/L); and aspartate aminotransferase, 246 U/L (normal range, 8-33 U/L). A liver sonogram demonstrated no findings of cirrhosis or fibrosis.

Upon receiving a diagnosis of active hepatitis C, the patient acknowledged that she’d had unprotected heterosexual intercourse and shared used insulin syringes with friends.

THE DIAGNOSIS

Consideration was given to a diagnosis of HCV arthropathy, which can present as an RA-like arthritis in HCV-infected individuals, in the differential diagnosis.¹ A cohort study found HCV-associated arthropathy occurred in 6.8% of those with chronic HCV infection.²

However, the symmetrical involvement of shoulders and knees as the patient’s primary arthralgias, and a rheumatologic work-up showing the presence of anticyclic citrullinated peptide antibody levels, confirmed the diagnosis of RA with coexisting HCV.

DISCUSSION

Delivering interdisciplinary care in a rural area

Although evidence-based guidelines and online HCV Treatment Path programs guided the initial evaluation of potential treatments for this patient, her multiple comorbidities prompted us to seek out additional, interdisciplinary advice through a resource for underserved communities called Project Extension for Community Healthcare Outcomes (ECHO; see “What is Project ECHO?^3,4”). The patient’s case was presented virtually, without identifying information, to a multidisciplinary HCV team. Two treatment options were suggested:

• sofosbuvir/velpatasvir (400 mg/100 mg) for 12 weeks or
• glecaprevir/pibrentasvir (100 mg/40 mg) for 8 weeks.

Both are evidence-based and recommended treatment options according to the HCV treatment guidelines issued jointly by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America.⁵

In most patients with HCV, treatment is guided by a number of factors, including pill burden, access to care, duration of therapy, drug interactions, and patient-specific needs. After analyzing all aspects of this patient’s case, 2 major concerns guided our shared decision-making process on treatment.

The best treatment is what works for the patient

Owing to the patient’s multiple comorbidities and prescribed medications for chronic diseases, concerns about possible medication interactions with the HCV treatment options were a factor in her HCV treatment plan. Additionally, the patient had significant social determinants of health barriers that made continued treatment and follow-up challenging.

The potential interaction of HCV infection treatment with the patient’s current methotrexate therapy for her RA was a primary concern. To determine the risk for interactions, the team used the University of Liverpool HEP/HIV Drug Interactions Checker, which helps identify possible interactions with these disease-specific medication therapies.⁶

Both sofosbuvir/velpatasvir and glecaprevir/­pibrentasvir have a potential interaction with methotrexate and are driven by a similar mechanism. Methotrexate is a substrate of the Breast Cancer Resistance Protein efflux transporter (BCRP), and the components of both sofosbuvir/velpatasvir and glecaprevir/pibrentasvir are inhibitors of BCRP.⁷ The inhibition of this efflux transporter can lead to an increased concentration of methotrexate, increasing the risk for methotrexate toxicity.⁷

Since no quantitative data exist regarding the degree of inhibition that these HCV drugs exert on BCRP, the team considered ­sofosbuvir/velpatasvir and glecaprevir/­pibrentasvir to have equal risk with regard to potential for drug interactions.

The patient’s barriers to treatment were another area of concern that directed our therapy decision. The patient had multiple barriers, including poor access to health care because of transportation issues, multiple children requiring care, a variety of chronic diseases, and other life stressors. Shared decision­-making ensured our patient’s autonomy in choosing a specific treatment.

This case shines a light on the multiple challenges that could have come between our patient and proper treatment—but ultimately, did not.

The patient’s social situation and preference narrowed the team’s basis for medication choice primarily down to the duration of therapy: 8 weeks of glecaprevir/pibrentasvir vs 12 weeks of sofosbuvir/velpatasvir. The patient mentioned multiple transportation challenges for follow-up visits to the clinic and therefore wanted to utilize the shorter treatment duration. Follow-up is needed every 4 weeks, so the patient was able to go from 3 to 2 visits.

For problems, there are solutions. Following careful consideration of these patient-specific factors and preferences, the team decided to begin therapy with glecaprevir/pibrentasvir. The patient worked with an outreach specialist at the FQHC to coordinate care and complete paperwork for the Project ECHO consultation. The outreach specialist also assisted the patient in completing paperwork for the Patient Assistance Program for HCV treatment. Because the patient is being cared for at an FQHC, the clinic’s in-house pharmacy was able to utilize the 340B Federal Drug Pricing Program, which makes otherwise out-of-reach medicines affordable for patients such as ours.

Our patient has had no issues with treatment adherence, adverse effects, or follow­-up appointments. The patient’s RA symptoms have improved significantly without any discernable worsening of her HCV infection.
