目的:探讨乳腺叶状肿瘤的预后因素。方法:对有随访结果的203例肿瘤的15个临床、病理学参数作统计学Log-Rank检验和Cox单及多因素分析。 结果和结论:术式、核分裂、瘤细胞异型性、肿瘤性坏死、瘤组织分化方向、瘤实质内薄壁血管数、单视野内核分裂增多、病理性核分裂、切除后复发、组织学等级和间质细胞密度11个参数为单风险因素,核分裂和肿瘤性坏死是独立的风险因素。
Objective: To investigate the prognostic factors of breast phyllodes tumor. Methods: The clinical and pathological parameters of 203 patients with follow-up results were analyzed by Log-Rank test and Cox single and multivariate analysis. RESULTS AND CONCLUSION: The operative procedure, mitosis, tumor atypia, neoplastic necrosis, tumor differentiation, the number of thin-walled vessels in the tumor parenchyma, increased single-field mitosis, pathologic mitosis, resection recurrence, histological grade and inter- Eleven parameters of stromal cell density were single risk factors, and mitotic and neoplastic necrosis were independent risk factors.
