自1972年～1990年，我院共收治乳腺病人1959例，其中，老年女性原发性乳腺癌117例，占同期收治病人的6．1％，非老年对照组病人595例，用Kaplan—Meier估计和log—rank检验及Breslow检验对四个有显著影响的预后因素进行单因素分析和调整分析，结果表明，老年乳腺癌死亡率显著高于非老年组病例。 From 1972 to 1990, 1959 cases of breast patients were treated in our hospital. Among them, 117 cases of primary breast cancer in elderly women accounted for 6.1% of patients admitted in the same period, and 595 cases of non-elderly controls were treated with Kaplan-Meier. Estimates, log-rank test, and Breslow test performed univariate analysis and adjustment analysis on four prognostic factors with significant effects. The results showed that the mortality rate of elderly breast cancer was significantly higher than that of the non-elderly group.
