BACKGROUND

While the MISSION Act for community care has increased Veteran access to specialty services, this has caused considerable fragmentation of care and financial cost to U.S. taxpayers. The VA Salt Lake City Health Care System (VA SLCHCS) referral area spans 125,000 square miles, one of the largest geographic regions in the VA health care system. Numerous VA Community- Based Outpatient Clinics (CBOCs) have been established in central and southern Utah, eastern Nevada, and southern Idaho; however, these clinics do not currently provide specialty services.

DISCUSSION

In conjunction with the National Oncology Program’s Close to Me project team, we conducted a cost analysis to determine financial feasibility of providing low-risk oncology parenteral therapies at rural CBOCs. Based on FY22 DO Paid Claim PowerBI and Pyramid Analytics Reports, VA SLCHCS paid claims for Community Care Hematology/Oncology community services in excess of $5.7 million for 380 unique Veterans (approximately $15,060 per unique Veteran). Comparatively, Veterans received high quality oncology care through VA SLCHCS with an estimated average cost of care of $5,424 per unique Veteran. Cost of parenteral therapies was estimated via review of Community Care Paid Claims Reports for individual drug claim costs (based on Jcode), VA drug pricing data from the VA National Acquisition Center Catalog, and drug unit claims data. The unit price of VA-care and community care costs were calculated and drug cost at the VA versus non- VA was compared. By retaining or re-establishing Hematology/Oncology Veteran care within VA, we estimate cost savings of approximately $9,636 per unique Veteran.

CONCLUSIONS

By re-establishing oncology care within VA SLCHCS the facility could net a substantial cost savings while simultaneously making Veterans lives easier, reduce need for transportation to/from the main SLC VA site, decrease costs due to VA pricing contracts, lessen Veteran out-of-pocket costs, improve care coordination through use of one electronic medical record, and maintain Veteran care within VA SLCHCS. Additionally, VA SLCHCS oncology will help lead the effort to launch a system within the CBOC’s to deliver high-cost parental therapies that could benefit other medical specialties such as gastroenterology, dermatology, and rheumatology.

PURPOSE

To evaluate if low molecular weight iron dextran (LMWID) is a safe and effective alternative to iron sucrose for intravenous iron administration.

BACKGROUND

In recent years, intravenous iron administration has increased due to clinical indications and rapid iron repletion. Early IV iron formulations had safety concerns that precluded widespread use. High molecular weight iron dextran was removed from the US market in 2009 due to safety concerns. Since then, several new IV formulations including LMWID and iron sucrose have been approved with a favorable benefit risk profile. While recent evidence and guidelines indicate that LMWID and other iron formulations have comparable safety profiles, no head-to-head comparisons exist. Both iron sucrose and LMWID are used for the treatment of IDA in Veterans Affairs hospitals. Iron sucrose is given 200 mg weekly for 5 weeks, while LMWID is given as a single 1-gram dose over 3 hours. We conducted a retrospective crosssectional analysis to compare the safety and efficacy of IV LMWID to IV iron sucrose.

METHODS

We identified 129 patients (LMWID: n=29, iron sucrose: n=100) who received intravenous iron from 01/01/2022 to 03/03/2023. To match the sample size, we selected every 3rd patient from the iron sucrose group (n=33). We captured data on infusion-related reactions, history of asthma/inflammatory bowel disease/> 2 drug allergies, overall and ≥ 2 g/dL hemoglobin increase, and treatment cost. Descriptive statistics were used to describe the safety and efficacy parameters. An unpaired t-test was used to calculate statistical significance of the cost.

RESULTS

We found that 82.7% of the patients who received LMWID had an increase in hemoglobin vs. 60.6% in the iron sucrose group. 48.3% of patients in LMWID had ≥ 2 hemoglobin increases vs. 27.3% in the iron sucrose group. The cost for LMWID administration was $2016.10, compared to $2315.40 for administration of IV iron sucrose cost. Two-tailed p value < 0.0001 indicating the observed difference to be statistically significant. No infusion reactions were observed in both groups.

CONCLUSIONS

In this single center analysis, IV LMWID administered provided comparable safety, and improved effectiveness, and cost-effectiveness to iron sucrose.

PURPOSE

To construct a composite score representing modifiable lifestyle and environmental risk (e-score) and test for associations with colonoscopy findings among US Veteran participants of CSP #380.

BACKGROUND

Understanding environmental and genetic risks beyond self-reported family history is a way to develop personalized colorectal cancer (CRC) screening. The Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO) study examined CRC risk stratified by sex and included an e-score along with genetic risk scores, where higher scores indicated higher risk. Both e-scores and genetic risk scores were significantly associated with CRC risk and models that included these were more robust than models that only included family history.

METHODS

CSP #380 is a prospective study of outcomes during colonoscopy screening (1994-97) and follow- up (1994-2009) for 3,121 asymptomatic Veterans aged 50-75. The dichotomous outcome of interest was most significant colonoscopy findings (MSCF) of i) advanced neoplasia (AN: ≥10mm adenomas or advanced histology, or invasive CRC) vs. ii) non-advanced adenomas (<10mm with tubular histology) or no neoplasia. The independent variable, e-score, was weighted according to the GECCO male sample and comprised BMI, height, diabetes, NSAID use, education, alcohol intake, smoking, exercise, and diet.

DATA ANALYSIS

Logistic regression was used to test associations between MSCF and e-scores, controlling for age, family history and number of colonoscopies.

RESULTS

Among 2,846 participants with complete data, 33.3% were aged 50-59 at baseline, 97% were male, and 83.8% were White. Those with AN (n=405, 14.2%) compared to those without AN (n=2,441, 85.8%) had higher median e-scores (29.5, range:0-99.8 vs. 29.0, range:5.2-100), suggesting a difference. The logistic regression models showed older participants (aOR: 1.04, 95% CI: 1.03-1.06) and those with more colonoscopies (aOR: 1.19, 95% CI: 1.06-1.33) had higher odds for AN. However, e-scores and family history were not significantly associated with MCSF.

IMPLICATIONS

E-scores were not significantly associated with MSCF in this preliminary study. Developing escores among a larger, diverse sample (N~381,695) of US veterans in the Million Veterans Program study will allow for stratified models in investigations of environmental and genetic risk for CRC. Outcomes from those analyses will support advances in screening guidelines with tailored programs for long-term CRC prevention.

BACKGROUND

Tobacco use is a known factor in oncologic outcomes in Veterans. Lung cancer is not only the leading cause of cancer death in the U.S., but it is also more prevalent among Veterans. Tobacco use is underassessed and undertreated in healthcare settings. Newly diagnosed cancer patients seen at the Day-Treatment Center of Edward Hines Jr. VA Hospital were not consistently screened for tobacco use or appropriately referred to the hospital-based Tobacco Cessation Program.

PURPOSE

This quality improvement project was created to use existing resources to increase the percentage of newly diagnosed cancer patients screened for tobacco use based off the CoC Just ASK Quality Improvement Project and Clinical Study.

METHODS/DATA ANALYSIS

Using Plan-Do-Study- Act (PDSA) quality improvement methodology, a multidisciplinary team led by Oncology Nursing, Oncologists, Pharmacy, Social Work and Behavioral Health, to standardize processes to increase the percentage of tobacco use screening. The primary intervention was designating nurse educators to standardize the cancer treatment education process to include an assessment for tobacco by using the Just ASK criteria. The primary study goal was to increase tobacco use screening from 54.8% (Baseline Data) to 85% (Target State Goal).

RESULTS

Baseline number of tobacco screening in 2021 was 54.8%. From 1/1/22-6/30/22, 52.8% were screened using the Just ASK criteria. After the first PDSA cycle, from 7/1/22-12/31/22, tobacco screenings increased to 95.1%. PDSA cycle two revealed a 25% increase in Q1 accepting referrals. 62.5% of positive tobacco users agreed to accept care compared to 25% in PDSA cycle one.

CONCLUSIONS/IMPLICATIONS

The quality study met the primary goal of screening newly diagnosed cancer patients. The success of this project supported the use of existing VA hospital-based program resources such as educational materials, supportive medication, and behavioral counseling. Interventions directed at standardization of clinical workflow processes through nursing education and linkage to resources increased tobacco screening among newly diagnosed Veterans with cancer. Planned PDSA cycle two will spread standardized processes in the Rad/Onc Department and build capacity to offer smoking cessation assistance to newly diagnosed cancer patients who report as a current smoker. Annual VHA clinical reminders will be built in and satisfied by using an EMR tobacco screen template.

INTRODUCTION

Medulloblastoma (MB) is rarely seen in adulthood. Treatment guidelines are derived from studies of the pediatric population, results favoring the Packer regimen (cisplatin plus cyclophosphamide or lomustine plus vincristine). MB rarely has extraneural metastases, especially the bone marrow.

CASE PRESENTATION

A 32-year-old female with a past medical history of cerebellar MB confirmed on surgical pathology status post resection, weekly radiation and vincristine treatment presented to us in clinic to re-establish care. She was lost to follow-up 9 months after initial diagnosis and wished to continue treatment. She was started on Lomustine, Cisplatin and Vincristine after discussion with our colleagues at MSKCC, where she had received her initial treatment. After cycle three, she developed intractable bone pain and pancytopenia. Bone marrow biopsy revealed metastasis of Sonic Hedgehog Desmoplastic/nodular variant MB. PET and CT imaging confirmed metastatic disease in the bone marrow and repeat MRI brain showed abnormal nodular enhancement. CSF analysis to assess for spinal metastasis was negative. The patient was started on Temozolomide, Irinotecan and Bevacizumab with significant improvement in bone pain and radiological improvement noted on PET and CT scans. After cycle six, the patient had increased bone pain and repeat FDG-PET showed increased uptake, however, she continued to receive treatment and her pain has improved off narcotics.

DISCUSSION

We highlight a case of adult MB in the bone marrow responsive to temozolomide, irinotecan and bevacizumab. We conducted a literature search using PubMed, Medline and Web of Science between 1990 to 2022. In 2021, COG Phase 2 screening trial showed bevacizumab, temozolamide/irinotecan therapy significantly reduced the risk of death with recurrent MBs, two studies included patients up to 21 and 23 years of age. Other modalities showing some response include Vincristine plus cyclophosphamide as well as high dose carboplatin, thiotepa and etoposide alongside autologous SCT. Vismodegib has also shown varied response of 15 months in two adults with extraneural MB metastasis. Given the unique entity of adult MB and extraneural metastasis, limitations include small sample and lack of generalizability.

CONCLUSIONS

Extraneural metastasis of MB yields a poor prognosis. Future considerations include randomized trials to establish efficacy of Temozolomide, Irinotecan plus Bevacizumab in this population.

DISCUSSION

We highlight a case of adult MB in the bone marrow responsive to temozolomide, irinotecan and bevacizumab. We conducted a literature search using PubMed, Medline and Web of Science between 1990 to 2022. In 2021, COG Phase 2 screening trial showed bevacizumab, temozolamide/irinotecan therapy significantly reduced the risk of death with recurrent MBs, two studies included patients up to 21 and 23 years of age. Other modalities showing some response include Vincristine plus cyclophosphamide as well as high dose carboplatin, thiotepa and etoposide alongside autologous SCT. Vismodegib has also shown varied response of 15 months in two adults with extraneural MB metastasis. Given the unique entity of adult MB and extraneural metastasis, limitations include small sample and lack of generalizability.

CONCLUSIONS

Extraneural metastasis of MB yields a poor prognosis. Future considerations include randomized trials to establish efficacy of Temozolomide, Irinotecan plus Bevacizumab in this population.

BACKGROUND/PURPOSE

Tumor lysis syndrome (TLS) occurs when malignant cells rapidly break down. This may lead to hyperuricemia, hyperkalemia, hyperphosphatemia, and/or hypocalcemia. Rasburicase reduces uric acid in cancer patients undergoing anti-cancer therapy. However, caution is required as rasburicase is contraindicated for patients with glucose- 6-phosphate dehydrogenase (G6PD) deficiency due to the increased risk of hemolysis. G6PD deficiency is more prevalent among African Americans (AA), affecting approximately 12% of this population. The FDA recommends testing for G6PD deficiency in higher risk groups before administering rasburicase.

METHODS

A retrospective analysis was conducted at the Louis Stokes Cleveland VAMC from February 1, 2018, to January 31, 2023 addressing appropriate use of rasburicase and incidence of G6PD deficiency and hemolysis. Appropriate use was defined by: TLS (2 or more: uric acid ≥ 8 or 25% increase; K+ ≥ 6.0 or 25% increase; Phos > 4.5mg/dL, or 25% increase; or calcium < 7, or 25% decrease, from baseline) or at high risk for TLS (CLL: venetoclax use w/lymph node > 10cm or WBC > 25k and elevated uric acid; AML: WBC > 100k; ALL: WBC > 100k and LDH 2x ULN; Burkitt lymphoma: LDH 2x ULN).

RESULTS

50 patients were identified who received rasburicase. 21/50 (42%) did not meet criteria for appropriate use. 44/50 (88%) underwent G6PD testing. The average time from G6PD testing order to obtaining the results was 3.4 days; 18/50 patients (36%) had G6PD resulted prior to rasburicase administration, and 26 patients (52%) received rasburicase prior to G6PD results. Overall, 13/50 (26%) were AA. Of the AA pts, 12/13 (92%) were tested for G6PD. Of these 12, 1/12 was found to be G6PD deficient and this patient experienced G6PD deficiency-induced hemolysis after rasburicase. None of the non-AA pts (0/31) tested were found to be G6PD deficient.

IMPLICATIONS

There was a high (42%) level of inappropriate use of rasburicase. G6PD deficiency was uncommon and only found in the AA population. To reduce inappropriate use, rasburicase orders will be restricted to medical oncology. G6PD testing will be limited to AA pts, with pathology to develop a rapid turnaround time for results prior to rasburicase administration to prevent hemolysis.

BACKGROUND

Minimal residual disease (MRD) testing in myeloma has been shown to be a strong prognostic marker for progression-free and overall survival. Limited data suggest MRD results may also be useful for therapy discontinuation decisions. The clonoSEQ Assay utilizes next generation sequencing involving a bone marrow sample, obtained at the time of diagnosis, to identify patient-specific sequence(s).

DISCUSSION

The same methodology is then applied later to assess for MRD. Although widely adopted at most US academic centers, there has been limited use of MRD across VA centers. In 2022 the Cleveland Louis Stokes VAMC partnered with Adaptive Biotechnologies to develop a process for MRD/clonoSEQ testing in myeloma pts. Hematology, Pathology, Medicine, Administration and Adaptive Biotechnologies representatives met to develop a streamlined process for ordering, sample procurement, billing and result documentation. In 5/2022 the 1st specimen was sent. EQUATE is a national cooperative group trial requiring baseline clono- SEQ testing with a positive sequence ID. Daratumumab hyaluronidase (part of standard treatment) is provided to the institution at no cost on the trial but otherwise would cost the VA $5,797.38/dose. clonoSEQ costs VA $1950/test. There have been 14 specimens sent involving 12 pts: 12 baseline marrow and 2 for MRD (posttransplant). All of the baseline specimens were found to have an identifiable sequence. Both of the MRD tracking specimens were positive. The average turnaround time for clonoSEQ results was 13.2 days (range 7 to 18 days). 4 of the 12 pts with a positive initial clonoSEQ ID qualified for the EQUATE trial but would not have been deemed eligible without the baseline clonoSEQ results. 2 of these pts have enrolled on the trial and started treatment. Costs for 14 clonoSEQ tests: $27,300. Estimated cost savings for the 2 pts enrolled onto EQUATE: $127, 542.36/pt/year= $255,084.72/year. Overall cost savings: $227,784.72.

CONCLUSIONS

An efficient process for baseline and post-treatment (MRD) clonoSEQ testing in myeloma pts was developed. Although expensive, use of this test resulted in significant overall cost savings by allowing enrollment onto a clinical trial. In addition, if studies determine that negative MRD results can guide therapeutic decisions, use of clonoSEQ testing may result in further benefits.

PURPOSE

To analyze associations between colorectal cancer progression and diet scores calculated using published scoring approaches for three dietary patterns: Healthy Eating Index (HEI), Mediterranean Diet (Mediterranean), and Dietary Approaches to Stop Hypertension Diet (DASH).

BACKGROUND

Little is known about whether longterm risk for progression to colorectal cancer is associated with recommended healthy dietary patterns among US veterans. Previous studies of veterans have shown higher intake of fiber and vitamin D reduced risk, and red meat increased risk for finding colorectal cancer precursors during colonoscopy. However, studying dietary patterns in aggregate may be more clinically relevant for longitudinal studies of colorectal cancer prevention.

METHODS

3,121 asymptomatic US veterans aged 50-75 received colonoscopy between 1994-97 and were followed through 2009. Most significant colonoscopy findings (MSCF) across the study period were: (i) no neoplasia (NN), (ii) non-advanced adenomas (NAAs) or (iii) advanced neoplasia (AN). Baseline dietary questionnaire data were used to calculate three dietary pattern (HEI, Mediterranean, and DASH) scores.

DATA ANALYSIS

Multinomial logistic regression models were used in a cross-sectional analysis to test for associations represented by adjusted odds ratios (aOR) between MSCF and dietary pattern scores, controlling for demographics and clinical risk factors.

RESULTS

Among 3,023 participants with complete data, 97% were male, and 83.8% were White. Increasing scores, representing healthier diets, for each dietary pattern had similar or lower odds for NAAs and AN, respectively, versus NN. They were HEI: aOR: 1.00, 95% CI: 0.99-1.01 and aOR 0.97, 95% CI: 0.99-1.01; Mediterranean: aOR: 0.98, 95% CI: 0.95-1.02 and aOR 0.95, 95% CI: 0.90-0.999; DASH: aOR: 0.99, 95% CI: 0.99- 1.00 and aOR 0.99, 95% CI: 0.98-0.999. Across each dietary pattern, higher whole grain and fiber category scores generally had lower odds for NAAs and AN.

CONCLUSIONS

Study results revealed that overall higher dietary quality and specific dietary components of whole grain or fiber intake, based on three different dietary patterns suggest lower odds for CRC precursors. Findings indicate potential differences in dietary intake patterns and more research is needed to determine the benefit of developing tailored CRC screening and surveillance clinical guidelines.

PURPOSE

Assess the clinical impact (CI) of UV-related DNA damage signatures (UVsig) in Veterans with cancer of unknown primary (CUP) and cancer of extracutaneous origin (CEO).

BACKGROUND

UVsig have been reported in CUP and CEO (i.e. head and neck cancer and lung cancer). The presence of UVsig suggests a cutaneous origin and potential misclassification of CEO using conventional histopathologic evaluation. Literature on the association of UVsig in pan-cancer genomics is limited.

METHODS

This is a retrospective study of Veterans who underwent comprehensive genomic profiling with FoundationOne CDx during 2/1/2019 to 9/30/2022 through the VA National Precision Oncology Program. The outcome was the CI of UVsig (high, medium, and low) determined by blinded chart reviews: (1) high: UVsig leading to change in diagnoses (CID) and a different first-line therapy (FLT) would have been offered; (2) medium: UVsig leading to CID, but appropriate FLT offered; (3) low: diagnoses modified by clinicians and treated as cutaneous cancers. NCCN Guidelines were referenced for FLT.

DATA ANALYSIS

Descriptive statistics and chi-square tests were utilized to evaluate the UVsig CI.

RESULTS

Among 5,565 cases with 10 or more assessable alterations for UVsig analysis, 650 (11.7%) were positive for UVsig. CUP and CEO cohorts each had 41 cases analyzed. In the CUP cases, 20 (48.8%), 9 (21.9%), and 12 (29.3%) were categorized as having high, medium, and low CI, respectively; and in the CEO cases, it was 22 (53.7%), 15 (36.6%), and 4 (9.8%). There was no difference statistically between the CUP and CEO groups on the percentage distribution of CI (p=0.06). Among the 42 out of 82 cases having high CI, 37 (88.1%) received cytotoxic chemotherapy without any indication, and 5 (11.9%) were not offered immunotherapy (IO) as FLT. More than half of the 82 cases had high CI; more than 90% of the CEO cases had high and medium CI.

IMPLICATIONS

UVsig serves as a useful biomarker for cancers with cutaneous origin. About 1% of the 5,565 cases analyzed had high UVsig CI. Knowledge of UVsig could lead to omission of chemotherapy (hence avoiding toxicities) or addition of IO (for potential benefits).

BACKGROUND/PURPOSE

Febrile neutropenia (FN) is considered a life-threatening oncologic emergency that requires prompt recognition of the condition and expeditious administration of antibiotics. In 2021, a neutropenic workgroup in the VA Northeast Ohio Healthcare System (VANEOHS) began working on updating the neutropenic policy to match current neutropenic guidelines. In 2022, the policy was approved, and the following changes were implemented (1) timing of antibiotic administration changed from two hours to one hour of fever presentation (2) absolute neutrophil count (ANC) criteria changed from an ANC of ≤ 1.0 K/cmm to an ANC of ≤ 0.5 K/cmm or an ANC that is expected to decrease to ≤ 0.5 K/cmm during the next 48 hours.

SYNTHESIS OF LITERATURE

Each hour that antibiotics are delayed is associated with a decrease in survival and an increase in mortality of 7.6% (Koenig et al, 2019).

INTERVENTIONS

The existing neutropenic policy, order sets, and antibiogram were updated. The physicians, pharmacists, and nurses from the neutropenic workgroup conducted educational in-services with their respective groups. Badge backers were created for inpatient nursing staff to wear as a quick reference. Posters were hung in the medicine team workrooms. A protected health information (PHI) Outlook email was set up to automatically generate, notifying workgroup members when initial antibiotics are administered to a patient with neutropenic fever. This email allows “real time” tracking of initial antibiotic administration. A certificate of recognition was created to email to nurses who administer antibiotics within the 1-hour timeframe.

RESULTS

Monthly chart audits of timing from fever presentation to antibiotic administration are conducted. Data is reported monthly at the neutropenic workgroup meetings. The following data was gathered after implementation and shows gram negative antibiotic administration within one hour of fever presentation: September 2022, 100% (n = 1), October 2022, 100% (n = 1), November 2022, N/A (n = 0), December 2022, N/A (n = 0), January 2023, N/A (n = 0), February 2023, 100% (n = 1), March 2023, 100% (n = 1), and April 2023, N/A (n = 0).

IMPLICATIONS

Continue to monitor data to ensure targets are met and reevaluate process as needed.

BACKGROUND/PURPOSE

Febrile neutropenia (FN) is considered a life-threatening oncologic emergency that requires prompt recognition of the condition and expeditious administration of antibiotics. In 2021, a neutropenic workgroup in the VA Northeast Ohio Healthcare System (VANEOHS) began working on updating the neutropenic policy to match current neutropenic guidelines. In 2022, the policy was approved, and the following changes were implemented (1) timing of antibiotic administration changed from two hours to one hour of fever presentation (2) absolute neutrophil count (ANC) criteria changed from an ANC of ≤ 1.0 K/cmm to an ANC of ≤ 0.5 K/cmm or an ANC that is expected to decrease to ≤ 0.5 K/cmm during the next 48 hours.

SYNTHESIS OF LITERATURE

Each hour that antibiotics are delayed is associated with a decrease in survival and an increase in mortality of 7.6% (Koenig et al, 2019).

INTERVENTIONS

The existing neutropenic policy, order sets, and antibiogram were updated. The physicians, pharmacists, and nurses from the neutropenic workgroup conducted educational in-services with their respective groups. Badge backers were created for inpatient nursing staff to wear as a quick reference. Posters were hung in the medicine team workrooms. A protected health information (PHI) Outlook email was set up to automatically generate, notifying workgroup members when initial antibiotics are administered to a patient with neutropenic fever. This email allows “real time” tracking of initial antibiotic administration. A certificate of recognition was created to email to nurses who administer antibiotics within the 1-hour timeframe.
