Injectable estrogens are options for gender-affirming hormone therapy per guidelines, which suggest intramuscular dosages of 5–30 mg every 2 weeks or 2–10 mg weekly with estradiol cypionate or valerate interchangeably. Data among transgender and gender-diverse patients are limited due to local unavailability and concerns around laboratory assay variability and estradiol (E2) level fluctuation. We note a concerning trend where patients are prescribed high-dose injections based on the guidelines leading to serum E2 levels well above the range recommended in the same guidelines. Our review indicates that 5 mg weekly or lower should be prescribed when initiating injectable estrogens to avoid supraphysiologic E2 levels.

Abstract Transgender and gender diverse (TGD) individuals face significant barriers to accessing health care. Recent introductions of regulatory policies at state and federal levels raise concerns over the politicization of gender-affirming health care, the risks of further restricting access to quality care, and the potential criminalization of healthcare professionals who care for TGD patients. The Endocrine Society and the Pediatric Endocrine Society have published several news articles and comments in the last couple of years supporting safe and effective gender-affirming interventions as outlined in the 2017 Endocrine Society’s Clinical Practice Guidelines. The Endocrine Society Position Statement on Transgender Health also acknowledges the rapid expansion in understanding the biological underpinning of gender identity and the need for increased funding to help close gaps in knowledge about the optimal care of TGD individuals. This Policy Perspective affirms these principles in the context of pending and future legislation attempting to discriminate against TGD patients while also stressing the need for science and health care experts to inform health policies.

PURPOSE To develop recommendations concerning the management of male breast cancer. METHODS ASCO convened an Expert Panel to develop recommendations based on a systematic review and a formal consensus process. RESULTS Twenty-six descriptive reports or observational studies met eligibility criteria and formed the evidentiary basis for the recommendations. RECOMMENDATIONS Many of the management approaches used for men with breast cancer are like those used for women. Men with hormone receptor–positive breast cancer who are candidates for adjuvant endocrine therapy should be offered tamoxifen for an initial duration of five years; those with a contraindication to tamoxifen may be offered a gonadotropin-releasing hormone agonist/antagonist plus aromatase inhibitor. Men who have completed five years of tamoxifen, have tolerated therapy, and still have a high risk of recurrence may be offered an additional five years of therapy. Men with early-stage disease should not be treated with bone-modifying agents to prevent recurrence, but could still receive these agents to prevent or treat osteoporosis. Men with advanced or metastatic disease should be offered endocrine therapy as first-line therapy, except in cases of visceral crisis or rapidly progressive disease. Targeted systemic therapy may be used to treat advanced or metastatic cancer using the same indications and combinations offered to women. Ipsilateral annual mammogram should be offered to men with a history of breast cancer treated with lumpectomy regardless of genetic predisposition; contralateral annual mammogram may be offered to men with a history of breast cancer and a genetic predisposing mutation. Breast magnetic resonance imaging is not recommended routinely. Genetic counseling and germline genetic testing of cancer predisposition genes should be offered to all men with breast cancer.
