Associations of type 2 diabetes and diabetes treatment with breast cancer risk and mortality: a population-based cohort study among British women.

Purpose: There is great interest in whether type 2 diabetes and its treatments alter breast cancer risk and prognosis, but previous studies are inconclusive. We conducted a cohort study within the UK General Practice Research Database to investigate associations of type 2 diabetes and patterns of diabetes treatment with breast cancer risk and all-cause mortality.

Methods: We identified 52,657 women with type 2 diabetes, diagnosed between 1987 and 2007, and 30,210 randomly selected women without diabetes.

Ovarian cancer survival population differences: a "high resolution study" comparing Philippine residents, and Filipino-Americans and Caucasians living in the US.

Background: In contrast to most other forms of cancer, data from some developing and developed countries show surprisingly similar survival rates for ovarian cancer. We aimed to compare ovarian cancer survival in Philippine residents, Filipino-Americans and Caucasians living in the US, using a high resolution approach, taking potential differences in prognostic factors into account.

Methods: Using databases from the SEER 13 and from the Manila and Rizal Cancer Registries, age-adjusted five-year absolute and relative survival estimates were computed using the period analysis method and compared between Filipino-American ovarian cancer patients with cancer patients from the Philippines and Caucasians in the US.

Epidemiology and clinicopathology of breast cancer in metro Manila and Rizal Province, Philippines.

The breast cancer incidence in the Philippines is among the highest in Asia. Age-standardized incidence rates (ASR) in Metro Manila and Rizal Province derived from the Philippine Cancer Society-Manila Cancer Registry and the Department of Health-Rizal Cancer Registry showed increase from 1980 to 2002, and were significantly higher in 7 cities in Metro Manila and significantly lower in 14 cities/municipalities mostly in Rizal Province. The AJCC Clinical Stage did not change from 1993 to 2002 among incident cases, the average distribution being: I= 5%, IIA= 20%, IIB= 18%, IIIA= 9%, IIIB= 10%, IV= 11%, Unknown= 28%.
