- To assess more precisely the relative risks associated with established risk factors for breast cancer, and whether the association between dietary fat and breast cancer risk varies according to levels of these risk factors, we pooled primary data from six prospective studies in North America and Western Europe in which individual estimates of dietary fat intake had been obtained by validated food-frequency questionnaires. Based on information from 322,647 women among whom 4,827 cases occurred during follow-up: the multivariate-adjusted risk of late menarche (age 15 years or more compared with under 12) was 0.72 (95 percent confidence interval [CI] = 0.62-0.82); of being postmenopausal was 0.82 (CI = 0.69-0.97); of high parity (three or more births compared with none) was 0.72 (CI = 0.61-0.86); of late age at first birth (over 30 years of age compared with 20 or under) was 1.46 (CI = 1.22-1.75); of benign breast disease was 1.53 (CI = 1.41-1.65); of maternal history of breast cancer was 1.38 (CI = 1.14-1.67); and history of a sister with breast cancer was 1.47 (CI = 1.27-1.70). Greater duration of schooling (more than high-school graduation compared with less than high-school graduation) was associated significantly with higher risk in age-adjusted analyses, but was attenuated after controlling for other risk factors. Total fat intake (adjusted for energy consumption) was not associated significantly with breast cancer risk in any strata of these non-dietary risk factors. We observed a marginally significant interaction between total fat intake and risk of breast cancer according to history of benign breast disease; with fat intake being associated nonsignificantly positively with risk among women with a previous history of benign breast disease; no other significant interactions were observed. Risks for reproductive factors were similar to those observed in case-control studies; relative risks for family history of breast cancer were lower. We found no clear evidence in any subgroups of a major relation between total energy-adjusted fat intake and breast cancer risk.

- ✓ A study of the overall management of ruptured posterior fossa aneurysms was conducted over a 1-year period (1993) in five neurosurgical centers in Sweden, serving a population of 6.93 million people. Forty-nine cases were identified and treated. One-third of the patients were in the seventh or eighth decade of life. Good overall management outcomes at 6 months were achieved in 30 cases (61%). The overall mortality rate was 27%. Patients with Hunt and Hess Grades I and II had a good overall recovery rate of 87%. On admission, 69% of the patients were assigned Hunt and Hess Grades III to V. The impact on patient outcomes of the intraoperative difficulties encountered, especially in the basilar tip area, is stressed. The authors found that delayed operation is not warranted in most cases. Frequent devastating rebleeding was observed among patients not offered early aneurysm clipping and the operative results were not at significant variance between the early and late surgical groups. Only 50% of the patients scheduled for delayed surgery ultimately made a good recovery, whereas 72% of patients scheduled for early operation did so. The data demonstrate that overall management results with posterior fossa aneurysms, comparable to achievements with supratentorial lesions, are within the reach of modern strategies, even in centers not specializing in these problems.
