Purpose To explore the antitumor activity of the aromatase inhibitor, anastrozole, in the treatment of premenopausal women with hormone receptor–positive, metastatic breast cancer who have been rendered functionally postmenopausal with the use of the luteinizing hormone-releasing hormone agonist, goserelin. Patients and Methods Premenopausal women with estrogen and/or progesterone receptor–positive, metastatic or recurrent breast cancer were enrolled in this prospective, single-arm, multicenter phase II trial. Patients were treated with goserelin 3.6 mg subcutaneous monthly and began anastrozole 1-mg daily 21 days after the first injection of goserelin. Patients continued on treatment until disease progression or unacceptable toxicity. Results Thirty-five patients were enrolled of which 32 were evaluable for response and toxicity. Estradiol suppression was assessed, with mean estradiol levels of 18.7 pg/mL at 3 months and 14.8 pg/mL at 6 months. One participant (3.1%) experienced a complete response, 11 (34.4%) experienced partial response, and 11 (34.4%) experienced stable disease for 6 months or longer for a clinical benefit rate of 71.9%. Median time to progression was 8.3 months (range, 2.1 to 63+) and median survival was not been reached (range, 11.1 to 63+). The most common adverse events were fatigue (50%), arthralgias (53%), and hot flashes (59%). There were no grade 4 to 5 toxicities. Conclusion The combination of goserelin plus anastrozole has substantial antitumor activity in the treatment of premenopausal women with hormone receptor–positive metastatic breast cancer.

BackgroundResponse rates to single agent immune checkpoint blockade in unselected pretreated HER2−negative metastatic breast cancer (MBC) are low. However, they may be augmented when combined with chemotherapy.MethodsWe conducted a single-arm, phase II study of patients with triple negative (TN) or hormone receptor-positive endocrine-refractory (HR+) MBC who were candidates for capecitabine. Patients were treated with pembrolizumab 200 mg intravenously day 1 and capecitabine 1000 mg/m2by mouth twice daily on days 1–14 of a 21-day cycle. The primary end point was median progression-free survival (mPFS) compared with historic controls and secondary end points were overall response rate (ORR), safety and tolerability. The study had 80% power to detect a 2-month improvement in mPFS with the addition of pembrolizumab over historic controls treated with capecitabine alone.ResultsThirty patients, 16 TN and 14 HR+ MBC, were enrolled from 2017 to 2018. Patients had a median age of 51 years and received a median of 1 (range 0–6) prior lines of therapy for MBC. Of 29 evaluable patients, the mPFS was 4.0 (95% CI 2.0 to 6.4) months and was not significantly longer than historic controls of 3 months. The median overall survival was 15.4 (95% CI 8.2 to 20.3) months. The ORR was 14% (n=4), stable disease (SD) was 41% (n=12) and clinical benefit rate (CBR=partial response+SD>6 months) was 28% (n=8). The ORR and CBR were not significantly different between disease subtypes (ORR 13% and 14%, CBR 25% and 29% for TN and HR+, respectively). The 1-year PFS rate was 20.7% and three patients have ongoing responses. The most common adverse events were low grade and consistent with those seen in MBC patients receiving capecitabine, including hand-foot syndrome, gastrointestinal symptoms, fatigue and cytopenias. Toxicities at least possibly from pembrolizumab included grade 3 or 4 liver test abnormalities (7%), rash (7%) and diarrhea (3%), as well as grade 5 hepatic failure in a patient with liver metastases.ConclusionsCompared with historical controls, pembrolizumab with capecitabine did not improve PFS in this biomarker unselected, pretreated cohort. However, some patients had prolonged disease control.Trial registration numberNCT03044730.
