Patterns of Fertility Preservation and Pregnancy Outcome After Breast Cancer at a Large Comprehensive Cancer Center.

BACKGROUND: In the last decades, long-term outcomes of breast cancer (BC) patients have improved, raising new survivorship issues, including fertility preservation and safety of pregnancy after BC. This study assesses evolution in patterns of fertility discussion/preservation over time and reports pregnancy outcomes in a cohort of young BC patients. METHODS: A retrospective cohort of 590 BC patients aged ≤40 diagnosed between 2000 and 2016 at a large cancer center was identified. Fertility counseling and preservation patterns for patients receiving chemotherapy were analyzed and compared for two cohorts: 2004-2006 and 2014-2016 (total n = 161). Outcomes were reported for patients with documented pregnancy after BC. RESULTS: Significantly, more patients diagnosed in 2014-2016 had evidence of discussion on fertility issues and/or application of fertility preservation techniques versus patients diagnosed in 2004-2006 (82.9% vs. 66.0%, p = 0.017). In particular, there was a significant difference in rate of documented fertility issues discussion (67.6% vs. 34.0%, p < 0.001). Age >35 and parity were associated with lower rates of fertility discussion/preservation. However, rates significantly improved over time (77.6% in 2014-2016 vs. 58.1% in 2004-2006 for patients aged >35, p = 0.046; 80.7% in 2014-2016 vs. 57.6% in 2004-2006 for patients with children at diagnosis, p = 0.018). Twenty-six patients with pregnancy after BC were identified; eight delivered at the age of >40. No complications for women or newborns were reported. Only two patients experienced BC relapse. CONCLUSIONS: In this small retrospective cohort, no safety concerns were identified for pregnancy after BC. The importance attributed by clinicians to address fertility issues has increased over time.

Update of the Phase III trial 'GRETA' of surgery and tamoxifen versus tamoxifen alone for early breast cancer in elderly women.

BACKGROUND: In the Phase III 'GRETA' trial 474 women aged ≥70 years with early breast cancer were randomly assigned to surgery plus tamoxifen for 5 years or tamoxifen alone for 5 years. This is a long-term update. PATIENTS & METHODS: Focusing on patients still alive in 2003, outcome end points has been recalculated. RESULTS: Median distant metastases disease-free survival is longer with tamoxifen alone for 5 years; (48.8 vs 37.9 months; p = 0.009). No difference was found in distant metastases rate, disease-free survival, breast cancer and overall survival. CONCLUSION: Primary endocrine treatment until the the best response, followed by minimal surgery and prosecution endocrine treatment for 5-10 years is a suitable option for elderly breast cancer patients. Delayed surgery does not prejudice overall survival.

Nipple-sparing mastectomy for breast cancer and risk reduction: oncologic or technical problem?

BACKGROUND: We evaluated the risks and benefits of nipple-sparing mastectomy in a multiinstitutional experience in the settings of risk-reducing surgery and breast cancer treatment. STUDY DESIGN: We analyzed data on 123 patients who had undergone nipple-sparing mastectomy with breast reconstruction for prophylaxis (n=55), treatment of breast cancer (n=41), or both (n=27) at four large centers. RESULTS: Median patient age was 45 years (range 22 to 70 years). There were 192 procedures (69 bilateral, 54 unilateral). Forty-four patients had invasive cancer; 20 had ductal carcinoma in situ (DCIS); 4 had phyllodes tumor. In all of these patients, the nipple tissue was cancer free on pathologic review. Median followup was 24.6 months (range 2.0 to 570.4 months). Local recurrence developed in two patients: one had DCIS in the upper-outer quadrant, with 71.8 months of followup; the other's cancer was invasive, in the upper-outer quadrant, with 6 months of followup. Distant metastasis developed in a third patient, who died 50 months after the procedure. Breast cancer developed in two patients after prophylactic mastectomy: one in the upper-outer quadrant at 61.8 months; one in the axillary tail at 24.4 months. No patients had recurrences in the nipple-areolar complex. Necrosis of the nipple was reported in 22 of 192 patients (11%) and it was judged minimal (less than one-third total skin of nipple) in 13 of 22 patients (59%). Overall cosmesis was judged by the patient and surgeon as good to excellent in the majority of patients. Level of satisfaction with cosmetic results was similar between prophylactic and treatment patients. CONCLUSIONS: The risk of local relapse was very low in our series of nipple-sparing mastectomies performed for DCIS or invasive cancer. Nipple-sparing mastectomy in the risk-reducing and breast cancer-treatment settings may be feasible in selected patients and should be the subject of additional prospective clinical trials.
