Who’s at higher risk for breast cancer recurrence?
New research shows that patients with ER-negative disease have a higher risk of a second breast cancer within a 5-year window post diagnosis, compared with patients with ER-positive disease.
“Our findings suggest that primary breast cancer ER status could be used to identify women at highest risk of second breast cancer events during the early post-treatment period and should be a consideration for guidelines and decision-making regarding surveillance imaging regimens for breast cancer survivors,” the study authors, led by Kathryn P. Lowry, MD, of Fred Hutchinson Cancer Center in Seattle, concluded.
The study was published online in Cancer.
Breast cancer survivors are at risk for a second breast cancer, making ongoing surveillance essential. Surveillance could be informed by better understanding an individual’s recurrence risk, but whether differences exist for women with ER‐positive vs. ER‐negative cancers remains unclear.
Dr. Lowry and colleagues analyzed women diagnosed with stage I-III breast cancer between 2000 and 2017, drawing from six Breast Cancer Surveillance Consortium registries. The team collected information on patients’ ER status as well as second breast cancer events detectable by surveillance imaging. Second breast cancer rates were assessed 1-5 years and 6-10 years after diagnosis. The final study cohort included 23,139 women with ER-positive disease and 4,605 with ER-negative disease.
The researchers found that, at the 5-year mark, the cumulative breast cancer incidence was 7.1% for ER‐negative disease and 3.6% for ER‐positive disease. At the 10-year mark, the cumulative breast cancer incidence was still higher for women with ER-negative disease – 11.8% vs. 7.5% among those with ER-positive disease.
Patients with ER-negative disease also had higher rates of second breast cancers within the first 5 years of follow-ups – 16.0 per 1,000 person‐years vs. 7.8 per 1,000 person‐years for those with ER‐positive breast cancer – though after 5 years, the rates by ER status were similar among the two groups (12.1 per 1,000 vs. 9.3 per 1,000 person‐years, respectively).
Overall, the findings indicate that the “ER status of the primary invasive cancer was an important prognostic factor for both the magnitude and the timing of second breast cancer events,” the authors concluded.
The team noted several limitations to their study, including that information on the presence of pathogenic variants, such as BRCA1 and BRCA2, were not available. Given that these variants tend to be more common among women with ER-negative breast cancers, this could represent a confounder.
Marisa C. Weiss, MD, chief medical officer and founder of Breastcancer.org, who was not involved in the research, highlighted two important details to keep in mind.
“We do know that triple negative breast cancers are associated with a higher risk of having an inherited genetic abnormality like BRCA1, which predicts a higher risk of second malignancies,” said Dr. Weiss, a breast oncologist at Lankenau Medical Center in Wynnewood, Pa. “Also, it should be noted that patients with HR-positive breast cancer have a higher incidence of local recurrence spread out over 10-plus years.”
What might these results mean for practice and following patients over the long term?
According to the researchers, “further study is needed to evaluate whether women with ER‐negative primary cancers may potentially benefit from more intensive surveillance in the early postdiagnosis period.”
Dr. Weiss noted as well that “each person’s situation is unique,” and it is “very important to develop a customized survivorship care plan with close surveillance,” which includes genetic testing.
Dr. Lowry reported grants from the American Cancer Society and personal fees from the Radiological Society of North America outside the submitted work. Several coauthors also reported disclosures. Dr. Weiss reported no relevant financial relationships.

Best estimates made for hydroxychloroquine retinopathy risk
A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.
HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.
Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.
The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.
The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.
Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”
A 2021 joint position statement from the American College of Rheumatology, American Academy of Dermatology, the Rheumatologic Dermatology Society, and the American Academy of Ophthalmology recommends a baseline eye exam within a few months after starting therapy, then additional screening at 5 years on HCQ and annually thereafter.
“Early detection of retinopathy is important in overall visual prognosis, because toxicity can continue even after discontinuation of the medication,” said Rukhsana G. Mirza, MD, professor of ophthalmology and medical education at Northwestern University in Chicago.
“Examination alone is not sufficient to evaluate early changes, and specialized testing must be done. These include color photos, visual field tests, optical coherence tomography, fundus autofluorescence and in some cases, multifocal electroretinogram. Also, the AAO [American Academy of Ophthalmology] has specific recommendations related to Asian patients as they may have a different pattern of retinopathy that must also be considered.”
More accurate risk measurements
This news organization asked study coauthor April Jorge, MD, assistant professor of medicine in the division of rheumatology, allergy, and immunology at Massachusetts General Hospital and Harvard Medical School, Boston, to discuss the study, how it correlates to past research, and what it adds that’s new and useful to rheumatologists and ophthalmologists:
Question: Your research found that a higher dose of HCQ in the first 5 years of treatment led to a greater risk of retinopathy. Is there any indication that a lower dose given more frequently, either within that 5-year period or longer, would pose a similar risk?
Answer: In our study, we assessed the HCQ dose in the first 5 years of use but followed patients who continued the medication longer than 5 years, through up to 15 years of use. Therefore, we compared the risk of HCQ retinopathy associated with different HCQ dosages but for the same duration of use. We found that for any dose of HCQ, the risk of retinopathy increases the longer the medication is used. However, patients who used a higher dose of HCQ had a higher risk of developing retinopathy over time.
Although current guidelines recommend avoiding any HCQ dose over 5 mg/kg per day to reduce the risk of retinopathy, we found a higher risk of retinopathy associated with dosing over 6 mg/kg per day than between 5 and 6 mg/kg per day and the lowest risk with dosing under 5 mg/kg per day.
Q: How does your study align with and/or expand upon previous research regarding HCQ risk?
A: An important prior study of hydroxychloroquine retinopathy was the 2014 study by Ronald B. Melles, MD, and Michael F. Marmor, MD, published in JAMA Ophthalmology. Prior to our present study, that was the largest study to use the modern screening method (optical coherence tomography) to detect HCQ retinopathy. That screening tool is more sensitive than older methods, so it can detect early/mild cases of retinopathy that are typically asymptomatic. Compared to older studies, that 2014 study found a much higher risk of HCQ retinopathy than was previously appreciated.
However, that 2014 study did have some key limitations that could affect the risk estimates, such as using prevalent cases. A key feature of our present study is that we took several important steps to generate more accurate risk estimates. This included using an incident user cohort and detecting incident retinopathy cases through serial review of optical coherence tomography (screening) studies.
To achieve a high degree of methodologic rigor in correctly identifying retinopathy outcomes, we had expert ophthalmologists perform masked adjudication of all screening studies, and we assessed the intra-rater reliability of these study interpretations. Therefore, our study adds to the literature more accurate estimates of retinopathy risk. We found a lower cumulative incidence of retinopathy than was identified in the 2014 study, but the risk is still noteworthy.
Also unique to our study, we graded the severity of HCQ retinopathy outcomes. This was important, as we found that the majority of retinopathy cases detected through routine screening are mild and presumed to be asymptomatic. This will likely be reassuring news for patients that we can screen for this adverse event to detect it early and prevent vision loss.
Another important difference was that we assessed the risk of retinopathy associated with using over 6 mg/kg per day, between 5 and 6 mg/kg per day, and less than 5 mg/kg per day, whereas the highest dosing group assessed in the 2014 study included all patients using over 5 mg/kg per day. The risk was considerably higher in the > 6 mg/kg per day group than in the 5-6 mg/kg per day group.
Q: How can rheumatologists and ophthalmologists use this new information specifically to better treat their patients?
A: Our study provides more accurate estimates of the risk of HCQ retinopathy than in prior studies. These risk estimates can be used when rheumatologists (and other clinicians who prescribe HCQ) consider the risks and benefits of this otherwise important and well-tolerated medication. The risk associated with different dose ranges could also inform dosing decisions, since dosing over 6 mg/kg per day may be more of a concern than using doses in the 5-6 mg/kg range. Ophthalmologists can also use these new risk estimates to counsel patients of the importance of HCQ retinopathy screening and can also hopefully provide some reassurance to patients that the risk of severe retinopathy is low as long as they are being monitored.

Inflation and health care: The prognosis for doctors
Rampant inflation doesn’t just mean a spike in everyday expenses like gas and groceries. It’s also bound to have a significant impact on the cost of health care – and on your practice. A recent report from McKinsey & Company predicts that the current inflationary spiral will force health care providers to charge higher reimbursement rates, and those costs inevitably will be passed along to both employers and consumers. Bottom line: Your patients will likely have to pay more out of pocket.
How, precisely, will inflation affect your practice, and what’s the best way to minimize the damage?
Step 1: Maintain operational standards
“Based on the conversations we’ve had with our physician clients that own practices, we see the potential for cost inflation to outrun revenue inflation over the next year,” said Michael Ashley Schulman, CFA, partner and chief investment officer at Running Point Capital, El Segundo, Calif. “Staff wages, as well as office equipment and medical supply costs, are increasing faster than insurance and Medicare/Medicaid reimbursement amounts.” Even so, topflight employees are essential to keep your practice running smoothly. Prioritize excellent nursing. Instead of adding a new hire, compensate your best nurse as well as possible. The same goes for an efficient office manager: On that front, too, you should go the extra mile, even if it means trimming expenses elsewhere.
Step 2: Plan ahead for insurance challenges
Many insurers, including Medicare, set health care costs a year in advance, based on projected growth. This means insurance payouts will stay largely the same for the time being. “Almost all physicians employed by large groups won’t see costs due to inflation rise until next year,” said Mark V. Pauly, PhD, Bendheim Professor in the department of health care management at the University of Pennsylvania, Philadelphia. “For self-employed physicians, there will also be a cushion.”
“The big issue with inflation is that more patients will likely be underinsured,” said Tiffany Johnson, MBA, CFP, co-CEO and financial advisor at Piece of Wealth Planning in Atlanta. “With more out-of-pocket costs ... these patients may not seek out medical treatment or go to see a specialist if they do not believe it is necessary.” A new study from Johns Hopkins found that patients under financial pressure often delay or forgo medical treatment because of food insecurity. Compassionate care is the solution: Direct these patients to financial aid and other resources they may qualify for. That way, they can continue to receive the care they need from you, and your need to pass on costs may be lower.
Step 3: Rely on your affiliated health care organization
These are tough times when it comes to expansion. “Since we are in an environment where inflation and interest rates are both high, it will be much harder for physicians to have the capital to invest in new technology to grow or advance their practice,” Ms. Johnson said. With that in mind, keep the lines of communication between you and your affiliated hospital/health care organization more open than ever. Combining practices with another doctor is one way to increase revenue; you might ask if any affiliated doctors are seeking to team up. It’s also vital to attend meetings and pay close attention to budget cuts your organization may be making. And don’t be shy about asking your administrator for profit-boosting recommendations.
Step 4: Revisit vendor relationships
Find out if your vendors will continue to supply you with the goods you need at reasonable rates, and switch now if they won’t. Be proactive. “Test new medical suppliers,” Mr. Schulman advised. “Reread equipment leasing contracts to check if the interest rates have increased. See if buyout, prepay, or refinancing options are more economical. Also, investigate [bringing down] your rental expense by reducing square footage or moving to a lower-cost location.” In light of ongoing supply chain issues, it’s wise to consider alternative products. But stay focused on quality – you don’t want to be stuck with cheap, possibly defective equipment. Spend where it’s essential and cut the fat somewhere else.
Step 5: Don’t waste your assets
Analyze your budget in minute detail. “Now is the time to review your current inventory and overhead costs,” Ms. Johnson said. “Many physicians let their office staff handle the restocking of inventory and office supplies. While this can be efficient for their practice, it also leaves room for unnecessary business expenses.” Take a cold, hard look at your supply closet – what’s in there that you can live without? Don’t reorder it. Then seek out any revenue stream you may be overlooking. “It’s important to review billing to make sure all the services are reimbursable,” Ms. Johnson added. Small mistakes can yield dividends if you find them.
Step 6: Be poised to pivot
Get creative. “To minimize a profit decline, use video consulting – it’s more efficient and less equipment intensive,” Mr. Schulman said. “Look at how remote work and flexible hours can maximize the work your practice accomplishes while cutting office costs.”
Ms. Johnson suggests adding concierge services, noting that “concierge doctors offer personalized care and direct access for an up-front fee.” With this approach, you may see fewer patients, but your payout paperwork will decrease, and that up-front fee can be profitable. Another outside-the-box idea: Start making house calls. A Scripps study found that home health visits requested via app can result in patient care delivered by a doctor and medical assistant in less than 2 hours. House calls can be an effective and profitable solution when it comes to providing nonemergency care and preventive treatment to patients who aren’t mobile, not to mention patients who just appreciate the convenience.
Step 7: Maintain transparency
Any economic changes your practice will implement must be communicated to your staff and patients clearly and directly. Keep everyone in the loop and be ready to answer questions immediately. Show those you work with and care for that, regardless of the economy, it’s they who matter to you most. That simple reassurance will prove invaluable.
