Abstract Background. We report on the activity of the combination of epirubicin and docetaxel given in neoadjuvant setting for 4 and 8 cycles respectively in 2 successive series of patients with large operable or locally advanced, hormone receptor positive, HER-2 negative breast cancer. Patients and methods. Patients were treated from 2002 to 2006 with epirubicin 90 mg/m2 and docetaxel 75 mg/ m2 intravenously, every 3 weeks for 4 cycles before and 4 cycles after surgery (Series I - 13 patients), and from 2006 to 2010 with the same regimen administered for 8 cycles preoperatively (Series II - 37 patients), plus hormonal therapy for 5 years and radiation therapy if indicated. All Series I and 32 Series II patients were able to complete the preoperative chemotherapy. Results. A complete response was found in 1 patient from Series I and 13 patients from Series II and the partial remission in 10 patients from Series I and 21 patients from Series II. Two Series I and 3 Series II patients did not respond clinically. Response rate (Series I/Series II) was 84/92%. All 50 patients underwent surgery. In Series I patients, 3 pCR occurred in the breast and the axilla was histologically negative in 2 cases. No evidence of disease both in the breast and in the axilla was achieved in 7.6% (1/13) of patients. In Series II patients, 8 pCR occurred in the breast and axilla was histologically negative in 15 patients. No evidence of disease both in the breast and in the axilla occurred in 10.8% (4/37) of patients. G3-G4 toxicity included myelosuppression in 3 patients from Series I and all patients from Series II, and mucositis in 1 patient from Series I and 4 patients from series II. No other G3-4 toxicities or toxic deaths occurred. Five-year progression free survival was 38% and 90% in Series I and Series II patients respectively. Conclusions. The incidence of pathologic complete remissions was lower in our patient population, compared to reported data. A longer duration of the preoperative treatment might be associated with a longer progression-free survival.

AbstractThe article gives an overview of current treatment options for metastatic hormone receptor-positive and HER2-negative breast cancer. The focus is on combined therapies, e.g., with CDK4/6 inhibition compared with purely endocrine-based therapies in the pre- and postmenopause, presenting the latest study results. The addition of a CDK4/6 inhibitor to endocrine-based therapy with an aromatase inhibitor or fulvestrant leads to a marked improvement in progression-free survival and is independently beneficial whether palbociclib, ribociclib or abemaciclib is involved. The particular clinical status of inhibition of cyclin-dependent kinases argues for its use in the first-line treatment of women with metastatic, hormone receptor-positive and HER2-negative breast cancer compared with the available purely endocrine-based therapies.

Background: Locoregional recurrence of breast cancer has significantly decreased over the last decades, particularly due to effective systemic therapy. While there is little controversy regarding local management of locoregional recurrences, in light of previous systemic treatment, additional chemotherapy regimens and their benefit to the patient are still subject to debate in tumors boards.Case Presentation: A 45-year-old woman was referred to our tertiary care center with a local recurrence of breast cancer 9 years after modified radical mastectomy for a ypT2N2a invasive ductal carcinoma. She received neoadjuvant treatment consisting of FEC-D (5-FU-epirubicin-cyclophosphamide, followed by docetaxel) for hormone receptor positive, HER-2-neu negative cancer in 2009, as well as adjuvant radiotherapy and tamoxifen for 9 years. After R0 resection of the hormone receptor positive, HER-2-neu negative recurrence in 2019, adjuvant therapy with ovarian suppression and an aromatase inhibitor was undertaken. A multigene assay identified a recurrence score at 37 and benefit from chemotherapy > 15%.Question: What would the ideal chemotherapy regimen consist of for this patient with an R0 resection of late recurrence of breast cancer?Conclusion: After reviewing history, imaging and pathology, members of the multidisciplinary team recommended treatment with Taxotere and cyclophosphamide (TC) x 4 for our patient.

1040 Background: Metaanalyses have demonstrated that 5% of initially HER2 negative breast cancer patients switch to HER2 positive during the course of the disease. Whether there is a difference in benefit from standard HER2 targeted therapies between patients initially HER2 positive and patients switching from negative to positive is unclear. We used data from the PRAEGNANT registry to compare the outcome of those patients. Methods: PRAEGNANT is a prospective advanced breast cancer registry (NCT02338167) focusing on molecular biomarkers. Patients in all therapy lines receiving any kind of treatment are eligible. This analysis compared progression-free survival (PFS) with standard HER2 targeted therapies between patients with tumors initially HER2 negative and switched to HER2 positive and patients with tumors that were initially HER2 positive adjusted for age and hormone receptor status. Results: At the time of this analysis 4061 patients with MBC were included in the PRAEGNANT registry, 49 of which met the requirements for this analysis. Median age was 56 (IQR 48-64) years and 87.8% of the patients were hormone receptor positive. At first diagnosis 15 patients were HER2 negative and 34 patients were HER2 positive. Within a median observation time of 9 months (95%CI: 3.8, 23.7) 35 PFS events occurred. Median observation time was 9 months (95% CI: 3.8, 23.7). Initially HER2 positive patients had a longer progression-free survival (HR = 0.49, 95% CI (0.24, 1.03), p = 0.07) as compared to initially HER2 negative patients switched to HER2 positive. The 1- and 2-year-PFS rates were also higher for patients initially HER2 positive: 1-year-PFS: 52% (95% CI: 36%, 73%) versus 26 % (95% CI: 12%, 52%); 2-year-PFS: 44% (95% CI: 29%, 67%) versus 19% (95% CI: 7%, 50%). Conclusions: Median PFS and 1- and 2-year PFS rate seem to be better in patients HER2 positive at initial diagnosis receiving standard HER2 directed therapies. Although our result has to be interpreted with caution because of the small cohort and the retrospective nature of our analysis, it justifies prospective research including the group of initially HER2 negative patients switched to HER2 positive as a distinct entity.
