Physical activity, early first delivery and residence as parameters for breast cancer prevention: an observational study.

PURPOSE: To determine the impact of physical activity, obesity, history of maternity, residence and socioeconomic status on the prevention of breast cancer (BC). METHODS: We established a questionnaire in order to record several potential parameters associated with BC in women aged between 30 and 60 years. The parameters evaluated in the present study were physical activity (years and days per week), obesity, age of menarche, age of first delivery, breast feeding, family history of BC, vegetarian diet, residence and socioeconomic status. RESULTS: A total of 120 women who worked in administrative jobs in large hospitals in Athens entered the study. Eleven of them had a history of BC. The multivariate logistic regression analysis revealed as independent risk variables for BC the following: family history of BC (p<0.001), absence of physical activity (p<0.001), first delivery after 35 years (p=0.011) and residence in city center (p=0.036). CONCLUSION: According to our results, because women who have family history of BC, sedentary and delivery after 35 years have higher risk to develop BC, risk reduction methods for these groups may need to be identified and implemented. Further studies are needed for the confirmation of our results.

Third-line hormonal treatment with exemestane in postmenopausal patients with advanced breast cancer progressing on letrozole or anastrozole. A phase II trial conducted by the Hellenic Group of Oncology (HELGO).

AIMS AND BACKGROUND: The understanding of hormonal therapies in postmenopausal women with metastatic breast cancer has advanced greatly in the past several decades. With the introduction of orally active, potent and selective third-generation aromatase inhibitors (anastrozole, letrozole and exemestane), approaches to the treatment of hormone-sensitive advanced breast cancer are undergoing reevaluation. For treatment of advanced or metastatic disease that has progressed on tamoxifen, all three agents are active. The purpose of the study was to assess the antitumor efficacy and tolerance of exemestane administered as third-line hormonal therapy to postmenopausal women with metastatic breast cancer refractory to letrozole and anastrozole. STUDY DESIGN: Sixty postmenopausal women with stage IV hormone receptor-positive carcinoma of the breast were enrolled in the study. All patients had received two prior hormonal manipulations and had measurable or assessable disease. All adverse events were monitored. RESULTS: Objective tumor response was achieved in 12 (20%) patients (95% CI, 9.6-30.4). The overall clinical benefit was 38.3% (95% CI, 21.2-49.3), and the median duration of objective tumor response was 20 months (range, 9-26). The median time to death was 17.4 months (95% CI, 16.14-18.66). CONCLUSIONS: Exemestane represents an active and well-tolerated treatment option in pretreated patients with advanced breast cancer who have received standard first- and second line hormonal therapies. By extending the sequence of hormonal therapy, disease progression and the need for chemotherapy may be significantly delayed.

Phase I/II trial of external irradiation plus medium-dose brachytherapy given concurrently to liposomal doxorubicin and cisplatin for advanced uterine cervix carcinoma.

BACKGROUND AND PURPOSE: Although the standard of care for patients with locally advanced uterine cervix carcinoma is cisplatin-(CDDP-)based chemotherapy and irradiation (RT), the optimal regimen remains to be elucidated. A phase I/II study was conducted to evaluate the dose limiting toxicity (DLT) and the maximum tolerated dose (MTD) of liposomal doxorubicin (Caelyx) combined with CDDP and RT for cervical cancer. PATIENTS AND METHODS: 24 patients with stage IIB-IVA were enrolled (Table 1). They all received external RT (up to 50.4 Gy) and two medium-dose rate (MDR) brachytherapy implants (20 Gy each at point A). The Caelyx starting dose of 7 mg/m2/week was increased in 5-mg/m2 increments to two levels. The standard dose of CDDP was 20-25 mg/m2/week. RESULTS: Concurrent chemoradiation (CCRT) sequelae and the DLTs (grade 3 myelotoxicity and grade 3 proctitis in five patients treated at the 17 mg/m2/week Caelyx dose level) are shown in Tables 2, 3, 4, and 5. After a median follow-up time of 17.2 months (range 4-36 months), four patients had died, 15 showed no evidence of progressive disease, and five (20.8%, 95% confidence interval [CI]: 12.5-29.1%) were alive with relapse (Figure 1). There were seven complete (29.1%, 95% CI: 19.8-38.4%) and 17 partial clinical responses (95% CI: 61.1-80.1%). The median progression-free survival was 10.4 months. Causes of death were local regional failure with or without paraaortic node relapse combined with distant metastases (Table 6). CONCLUSION: The MTD of Caelyx given concurrently with CDDP and RT was determined at the 12 mg/m2/week dose level. The above CCRT schema is a well-tolerated regimen, easy to administer in ambulatory patients, and results appear promising.
