目的:分析乳腺叶状肿瘤的临床表现和病理特征,探讨乳腺叶状肿瘤合理术式及手术技巧。方法:回顾分析12 a间手术治疗的乳腺叶状肿瘤32例的临床资料。结果:32例术前无确诊病例,均未行穿刺活检。行局部扩大切除30例,全乳切除2例,其中行局部扩大切除术的良性、交界性各1例在术后0.5 a、3个月复发,再行局部扩大切除,至今未再复发。随访2~10 a,局部复发率8.25%。结论:乳腺肿块是该病常见的首发症状,术前诊断困难,明确诊断主要依靠术中冷冻切片检查。直径<10 cm的良性、交界性的乳腺叶状肿瘤局部扩大切除术是可行的,预后良好。 Objective: To analyze the clinical manifestations and pathological features of breast phyllodes tumor and to explore the reasonable surgical procedures and surgical skills of breast phyllodes tumor. Methods: The clinical data of 32 cases of breast phyllodes tumor treated by surgery were retrospectively analyzed. Results: There were no confirmed biopsy cases in 32 cases before operation. Thirty cases underwent partial enlarging resection and two cases undergoing partial mastectomy. Among them, benign and borderline cases underwent partial enlarging resection in 0.5 and 3 months after operation, respectively. Follow-up 2 ~ 10 a, the local recurrence rate was 8.25%. Conclusion: The breast lump is the common first symptom of the disease. It is difficult to diagnose preoperatively. The diagnosis depends on the intraoperative frozen section examination. A benign, borderline lobular tumor of the breast with a diameter less than 10 cm is feasible and has a good prognosis.
