青年乳腺癌临床病理特点分子分型及预后分析

Clinico pathologic characteristics and molecular phenotypes of young breast cancer patients and their clinical significance

摘要

摘要:
目的探讨青年乳腺癌的临床病理特征、分子分型及预后情况。
方法收集天津医科大学肿瘤医院2002年1月至2009年12月经手术切除、病理证实的133例年龄≤30岁低龄青年乳腺癌病例，及同期117例年龄为31~35岁青年乳腺癌病例，并随机抽取同期年龄>35岁的中老年乳腺癌214例作为对照，回顾性分析其临床病理资料、分子分型及预后情况。
结果低龄青年乳腺癌、31~35岁青年乳腺癌与中老年乳腺癌在肿瘤大小、淋巴结转移、组织学分级、分子分型和肿瘤复发方面差异有统计学意义P < 0.05）。低龄青年乳腺癌更易出现三阴性乳腺癌、复发及远处转移P < 0.001），并且低龄青年乳腺癌与31~35岁青年乳腺癌、中老年乳腺癌相比，有较低的总生存率和无病生存率P < 0.05）。
结论年龄≤35岁青年乳腺癌症状隐匿，预后不佳，与中老年乳腺癌有不同的临床病理特征、分子分型及预后，应重视早期筛查与治疗。

Abstract:
Objective To study the clinico-pathologic characteristics, molecular phenotypes, and prognosis of young breast cancer patients.
Methods Data from 133 low-age (age≤30 years) young breast cancer patients and 117 young (31 years≤age≤35 years) breast cancer patients who underwent surgery between January 2002 and December 2009 were reviewed. Cases of the middle and old-age elderly (age >35 years) breast cancer patients during the corresponding period were randomly selected as matched controls. The clinico-pathologic characteristics, molecular phenotypes, and prognosis were retrospectively analyzed.
Results The low-age young and young breast cancer patients significantly differed from the elderly patients in terms of tumor size, lymph node metastasis, histological grading, molecular phenotype, and relapse (P < 0.05). The low-age young patients are more vulnerable to have triple-negative breast cancer, recurrence, and distant metastasis (P < 0.001). Moreover, the low-age young patients have lower overall survival and disease-free survival than the other groups (P < 0.05).
Conclusion Young breast cancer patients have poor prognosis compared with the elderly. Early screening and prompt treatment are necessary for young breast cancer patients.
