双侧乳腺癌（附14例报告）

自１９７２年至１９８９年，共收治乳腺癌９８４例。其中双侧性乳腺癌１４例（１．４％），均为女性。同时性５例（０．５％），异时性９例（０．９％），间隔时间为１０个月至１５年８个月，平均为５年８个月。年龄在３０～６４岁，平均４３．４岁。全部病例两侧乳癌病灶均经病理证实。作者认为对单侧乳癌治疗后患者应长期密切随访，对高危患者在对侧乳腺出现可疑病灶时应及时做活检。双侧乳腺癌的预后与肿瘤大小、腋窝淋巴结受累情况、治疗是否及时、正确，两侧病灶同时或异时发生及间隔时间的长短等因素有关。双侧乳腺癌经及时、积极、合理治疗后，预后并不差于单侧乳腺癌。

Bilateral Breast Cancer (A Report of 14 Cases)

From 1971 to 1989, 984 patients with primary breast carcinoma were treated in our hospital,Of them,14 cases (1.4% ) with bilateral breast cancer,there were 5 cases.of bilateralprimary synchronous breast cancer (0.5%) and 9 cases of bilateral primary metachronousbreast cancer (0.9%). The average age at first primary tumor is 43.4 years old for bilateralbreast cancer,the duration between the two kinds of cancer is 10 months to 15 years and 8months with a median of 5 years and & months. All patients undergoing pathological sectionof breast cancer should be followed closely,with particular emphasis on the opposite breast,and perioic physical examinations should be done. If there are any abnormal physical findingsin the opposite breast, a biopsy should be considered, especially for high-Risk group, and aprompt adequate treatment should be given. It is expected that the survival from bilateralbreast cancer should improve. The major prognostic factors still are the size of the tumor,themumber of axillary nodes involved,the level of involvement,the adequacy of the initial treatment,synchronous or metachronous bilaterality,the interval etc.
