ABSTRACT
PURPOSE: Because the currently available questionnaires to evaluate sexual changes on breast cancer women only address the sexual sphere with a few questions our purpose was to develop a questionnaire that assesses changes in sexual dysfunction and satisfaction in women treated for breast cancer. METHODS: A sample was selected of women aged between 18 and 65 who had had surgery for breast cancer, completed neoadjuvant/adjuvant chemotherapy treatment and could be receiving adjuvant hormonal treatment, with an active sex life at least 3 months before starting treatment. Metastatic disease was excluded. A questionnaire structured in 4 dimensions was developed. The MOS SF-12 and QLQ-BR23 questionnaires were also provided. The following metric properties were evaluated: item analysis; internal consistency; temporal stability; construct validity; concurrent, convergent and divergent validity; and feasibility. RESULTS: Three samples were recruited: a pilot sample of 20; a reduction sample of 152; and a validation sample of 148. The presence of 6 dimensions was confirmed: 1) Loss of sex drive; 2) worsening of body image; 3) psychological coping; 4) discomfort during intercourse; 5) satisfaction with sexual relations; and 6) satisfaction with breast reconstruction. Good goodness-of-fit statistics were obtained (χ2/df = 1.5, GFI = 0.9, AGFI = 0.84, CFI = 0.959, RMSEA = 0.062). Reliability was good (α = 0.855), as was test-retest stability (r = 0.838). The correlation with the convergent questionnaires proved to be higher than that obtained with generic measurements. CONCLUSIONS: We were able to develop a short questionnaire (17 items) capable of measuring sexual satisfaction in women with breast cancer with good metric properties.

BACKGROUND: Metastatic breast cancer remains largely incurable. Strategies involving the combination of the selective estrogen receptor modulator tamoxifen and chemotherapy have been abandoned in view of unacceptable toxicity because of thromboembolic events. The aim of this study was to investigate the safety and efficacy of the third-generation steroidal aromatase inhibitor exemestane plus chemotherapy. PATIENTS AND METHODS: Postmenopausal women with advanced breast cancer received 6 cycles of intravenous chemotherapy (5-fluorouracil [5-FU], epirubicin, and cyclophosphamide) and exemestane 25 mg/day that was continued after chemotherapy was completed. The primary efficacy endpoint was time to progression (TTP), and response rates were also assessed. Safety was assessed from adverse events. RESULTS: Twenty-three patients (median age, 62 years) were included in this study. Twenty patients completed 6 chemotherapy cycles. Median TTP was 13.7 months. Overall response was achieved by 20 patients (73.9%), and the clinical benefit rate was 87%. During the chemotherapy plus exemestane treatments, 50 adverse events were reported in 14 of the 23 patients (60.9%). As expected, the incidence of adverse events decreased during the phase of exemestane treatment alone (19 adverse events in 10 of 20 patients [50%]). There were 2 grade 4 events reported, pulmonary embolism and pneumonia, although pneumonia was not considered to be related. CONCLUSION: Although a small number of patients were included, the combination of exemestane and chemotherapy was well tolerated and only 1 thromboembolic event was reported. Response rates were similar to other comparable series and may encourage further studies to confirm the efficacy of chemotherapy in combination with an aromatase inhibitor.
