title: [The association of obesity with case distribution and prognosis of breast cancer].
abstract: We analyzed the association of obesity with case distribution and prognosis of breast cancer. We obtained the following results by using 1,587 breast cancer cases mastectomized between 1965 and 1974 at the Cancer Institute Hospital, Tokyo. 1) Non-invasive ductal carcinoma was prominent in non-obese patients. 2) The ratio of obese group was increasing as the patients became older. 3) Obese patients had bigger size of tumor and more advanced lymph node metastasis than non-obese patients. 4) In premenopausal patients but not in postmenopausal ones, obese group showed poorer 5-year survival rate than non-obese group (p less than 0.01), and it was true even after equalizing the tumor size and lymph node metastasis.
