The relation between body size and breast cancer remains uncertain, particularly with regard to differences between pre- and postmenopausal women. The authors examined whether height, weight, body mass index, and weight change were associated with breast cancer risk among pre- and postmenopausal women. This population-based case-control study included women aged 20-74 years (n = 6,548) who were diagnosed with invasive breast cancer during 1988-1991 in Maine, Massachusetts, New Hampshire, and Wisconsin. Similarly aged control women (n = 9,057) were selected at random from driver's license files and Health Care Financing Administration files. Height, weight, and information on other breast cancer risk factors were ascertained by telephone interview, and logistic regression was used to estimate multivariate-adjusted odds ratios and 95% confidence intervals. Among premenopausal women, the adjusted odds ratio for the upper quintile group of height relative to the lowest was 1.36 (95% confidence interval (CI) 1.05-1.76). The heaviest premenopausal women had a lower risk (odds ratio (OR) = 0.87, 95% CI 0.70-1.10). Among postmenopausal women, the adjusted odds ratios were higher for the upper quintile categories of both height (OR = 1.27, 95% CI 1.11-1.45) and weight (OR = 1.57, 95% CI 1.37-1.79). Weight gain since ages 18 and 35 years was associated with increased postmenopausal breast cancer risk, and risk was lower in women who had lost weight. These findings suggest that programs to avoid weight gain merit study as a means to reduce risk of postmenopausal breast cancer.
The maximum dose of Taxol recommended for phase II and III studies, when administered as a 3-hour infusion alone and with G-CSF support, is 210 mg/m2 and 250 mg/m2, respectively. No increased incidence of hypersensitivity reactions or other side effects were observed, with the possible exception of arthralgias and myalgias. If ongoing trials demonstrate that a 3-hour infusion is as efficacious as a 24-hour infusion, we conclude that with proper monitoring and premedication, high-dose Taxol can be safely administered in the outpatient setting.
A review of almost 1,200 children participating in the first and second National Wilms' Tumor Study (NWTS-1 and -2) has demonstrated a number of significant differences in the clinical presentation and response to therapy of anaplastic and nonanaplastic Wilms' tumor. Compared to their counterparts, children with anaplastic Wilms' tumor were generally one to two years older at diagnosis, more were non-white, and more had lymph node metastases at diagnosis. Consistent with previous studies, children with anaplastic Wilms' tumor survived for a significantly shorter time than those with non-anaplastic Wilms' tumor. A hopeful outlook, however, was suggested by the NWTS-2 experience since the more aggressive chemotherapies used in this study appear to have substantially improved the survival of patients with diffusely anaplastic tumors. Also, the survival of NWTS-2 patients with anaplastic Wilms' tumor was determined in part by clinicopathologic stage. It may be possible therefore to refine therapy according to stage so as to provide children with localized disease a chance for cure with fewer untoward treatment-related sequelae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
