Cholesterol and obesity as prognostic factors in breast cancer
摘要：
Analysis of disease-free survival rates in 374 women with operable breast cancer revealed that preoperative weight, particularly in combination with serum cholesterol, is a significant prognostic determinant. Overall, women weighing under 150 pounds had a significantly higher cumulative five-year disease-free survival rate (67%) compared with women weighing more (49%) ( z = 2.2298, P = 0.026). Women with low serum cholesterol levels had better cumulative five-year disease-free survival (67%) than women with high serum cholesterol levels (58%) ( z = 1.1008, P = 0.27). The combination of high weight and high serum cholesterol levels was associated with an extremely poor cumulative five-year disease-free survival (32%) compared with that observed for women in whom values of either, or both, variables were low (68%) ( z = 3.7843, P = 0.0004). These patterns in disease-free survival persisted even after controlling for tumor stage. The findings indicate that weight and cholesterol, in addition to their previously reported effect on the risk of breast cancer development, influence significantly the subsequent course of the disease.
