目的 观察乳腺叶状肿瘤的临床病理特征以及其与预后的关系。方法 选择2015年1月—2018年1月接受诊治的乳腺叶状肿瘤患者50例,评估乳腺叶状肿瘤的2年内复发情况和预后的相关影响因素。结果 乳腺叶状肿瘤50例,术后2年复发13例（26.00%）,与肿瘤大小、年龄、肿瘤性质、手术方式、核分裂、间质生长等因素密切相关,差异有统计学意义（P<0.05）。结论 良性乳腺叶状肿瘤的浸润性较差、进展较慢,发病较早,乳腺叶状肿瘤预后与核分裂、间质生长、手术方式、肿瘤性质、直径、发病年龄等因素密切相关。
Objective To investigate the relationship between clinicopathologic features and prognosis of breast phyllodes tumor. Methods Fifty breast phyllodes tumor patients treated from January 2015 to January 2018 in our hospital were enrolled in the study and assessed for two-year recurrence rate and influencing factors of prognosis. Results Among the 50 cases, 13 cases （26.00%） recurred in two years; the recurrence was closely related to tumor size, age, tumor type, operation method, nuclear division, and mesenchyma （P<0.05）. Conclusion Benign breast phyllodes tumor has the clinicopathologic features of poor invasion, slow progression, and early onset. Its prognosis is closely related to nuclear division, mesenchyma, operation method, tumor type and diameter, age of disease onset, etc.
