双侧原发性乳腺癌16例临床病理分析

目的 探讨双侧原发性乳腺癌的临床病理特征及其防治.方法 回顾性分析2001年1月至2009年12月江苏省肿瘤医院收治的确诊为双侧原发性乳腺癌16例的临床病理资料.结果 16例均为女性,占同期收治乳腺癌的0.47%,发病年龄41～69岁,中位年龄53岁.同时性双侧乳腺癌7例,发病年龄41～54岁,中位年龄47岁,5例为绝经前患者.异时性双侧乳腺癌9例,第2癌的发病年龄43～69岁,中位年龄58岁,1例为绝经前患者.异时性双侧乳腺癌第1癌与第2癌间隔14个月至196个月不等,中位间隔时间52个月.结论 同时性双侧原发性乳腺癌较异时性双侧乳腺癌发病年龄早,多见于绝经前.异时性双侧乳腺癌发生间隔时间不定,一侧发生乳腺癌后宜积极随访对侧乳腺,对雌激素受体阳性的患者应坚持内分泌治疗.

Diagnosis and treatment of bilateral primary breast cancer: a report of 16 cases

Objective To summarize our experience on diagnosis and treatment of bilateral primary breast cancer (BPBC). Methods Clinicopathologic records, including clinical manifestations, diagnosis and immunohistochemical expressions of 16 patients with BPBC, treated from 2001 to 2009 in Jiangsu Provincial Cancer Hospital, were analyzed retrospectively. Results The 16 patients with BPBC accounted for 0.47% of all patients diagnosed as malignant tumors of breast during the same period in our hospital. All of the 16 patients were women, with the median age of 53 years (ranged 41-69 years). 7 patients were in bilateral synchronous breast cancer (BSBC), with the median age 47 years (ranged 41-54 years), among whom 5 patients got BSBC just before menopause. 9 patients were in bilateral asynchronous breast cancer (BABC), with the median age 58 years (ranged 43-69 years), among whom 1 patient got BABC before menopause. The median interval between the first and second breast carcinoma of BABC was 52 months (ranged 14-196 months). Conclusions Compared with BABC, the occurrence age of the patients with BSBC was smaller. BABC was more common in premenopausal women. The interval time of BABC was irregular. The active follow-up after the occurrence of contralateral breast cancer and endocrine therapy for estrogen receptor-positive patients were recommended.
