Suboptimal Use of Effective Contraceptive Methods in Young Mexican Women With Breast Cancer.

PURPOSE: Contraceptive counseling and adherence in young women with breast cancer (BC) is a relevant issue because chemotherapy and hormonal treatment resulting in amenorrhea do not preclude unintended pregnancies. Currently, there is limited evidence from high-income countries; however, there are no studies regarding use of contraceptives in patients with BC in Mexico. This study aimed to determine the rate of contraceptive use in young Mexican women with BC during cancer treatment, characterize their contraceptive preferences, and assess contraceptive counseling by Mexican physicians. PATIENTS AND METHODS: A cross-sectional survey was conducted regarding contraceptive use and counseling among women age 40 years or younger at BC diagnosis who had completed chemotherapy in the previous 5 years or who were currently receiving long-term treatment with hormonal therapy and/or trastuzumab at a large tertiary health care facility in Mexico. RESULTS: Of a total of 104 eligible women with median age at diagnosis of 34 years, 51.1% reported using a contraceptive during chemotherapy and 45.7% reported using a contraceptive during other types of cancer treatment (hormonal therapy and trastuzumab). Of the 51 patients (49%) who were sexually active during chemotherapy, 76.5% used contraception, but only 29.4% used an effective contraceptive method. When asked about contraceptive counseling, only 16.7% recalled being advised by their health care provider. Sexually active women who received contraceptive counseling used contraceptives more often than women who were not counseled (83.3% v 22.2%). CONCLUSION: A minority of young women with BC in Mexico use effective contraception methods during cancer treatment and receive contraceptive counseling. Informing all premenopausal patients with BC about effective use of contraception methods during treatment should be an essential aspect of the supportive care of young women.

Neoadjuvant Chemotherapy Increases R0 Cytoreduction Rate But Does Not Improve Final Outcome in Advanced Epithelial Ovarian Cancer.

BACKGROUND: Most epithelial ovarian cancers present in advanced stages. Traditional management is maximum cytoreductive effort followed by platinum-taxane-based chemotherapy. We hypothesized that providing all chemotherapy before surgery will increase the R0 cytoreductive rate and improve prognosis. METHODS: Patients with advanced epithelial ovarian carcinoma [International Federation of Gynecology and Obstetrics (FIGO) stages IIIC and IV without parenchymal metastasis] were included in a comparative study. Group A underwent cytoreductive surgery followed by six cycles of chemotherapy, and group B completed six cycles of preoperative systemic therapy followed by cytoreduction. Demographic, clinical, surgical and pathologic variables were recorded and analyzed. Main outcome end points were progression-free survival (PFS) and overall survival (OS). Complete cytoreduction (R0) was defined as absence of macroscopic disease. Kaplan-Meier curves were constructed for survival analysis and univariate and multivariate analysis was performed. Significance was considered at p < 0.05. RESULTS: One hundred five patients were included: 42 in group A and 63 in group B. Mean patient age was 56 years (range 32-85 years). There were no significant differences between groups regarding demographic, clinical, surgical or pathologic variables. Surgical morbidity was low and not different between groups and there was no surgical mortality. R0 cytoreduction was obtained in 35.5 versus 64.5% in groups A and B, respectively. Median PFS and OS for the entire cohort were 16.17 and 38 months, respectively. Median PFS were 14.71 and 17.52 months for groups A and B, respectively (p = NS), and OS were 33.59 and 56.4 months for groups A and B, respectively (p = 0.08). Factors significantly associated with decreased survival on multivariate analysis were non-R0 resection (p < 0.001), anemia (Hb < 12 g/dL; p = 0.004) and comorbidities (Charlson score > 2; p = 0.007). CONCLUSIONS: In spite of nearly doubling the rate of complete cytoreduction and reduce severe surgical complications, preoperative chemotherapy does not improve long-term outcome in advanced epithelial ovarian carcinoma.
