摘要
1986年5月~2000年11月间,天津医科大学肿瘤医院对原发女性乳腺癌行保乳治疗174例,复习全部病历、钼靶X光片及病理切片,回顾性研究术后局部及远处失败的相关因素。随访12~196个月,随访率97.13%(169/174)。结果:1.局部复发9例,3年复发率3.79%(5/132):远处转移14例,5年转移率10.99%(10/91);5年生存率92.31%(84/91)。2.保乳手术无放疗组3年复发率(12.12%)显著高于手术加放疗组(1.01%),P<0.025。3.腋淋巴结阳性患者中保乳手术未化疗组5年远处转移率(44.44%)高于手术加化疗组(6.67%),P<0.05。4.切缘阳性与局部复发有关(P=0.0013)。5.乳腺癌诊断时年龄≤40岁、淋巴结阳性、组织学Ⅲ级与远处转移有关(P<0.05)。通过研究表明,保乳术后应放疗:切缘阳性者应再切除至阴性或全乳切除术;年轻、淋巴结阳性、组织学分级Ⅲ级者应辅助化疗。
Between May in 1986 and November in 2000, 174 patients with primary breast cancer were treated by breast-conserving therapy (BCT) in Tianjin Medical University Cancer Hospital. Their records, mammograms and pathological sections were reviewed. The purpose was to study the relative factors of local and distant failures after BCT retrospectively. The period of follow up was 12 to 196 months. The rate of follow up was 97.13%(169/174). Results: 1. There were 9 patients with local recurrence and 14 patients with distant metastasis. And 3-year recurrence rate was 3.79% (5/132);5-year metastasis rate was 10.99% (10/91); and 5-year survival rate was 92.31% (84/91). 2. 3-year recurrence rate for patients without radiotherapy (12.12%) was significantly higher than that with radiotherapy (1.01%), P<0.025. 3. In the group of patients with node-positive, 5 -year metastasis rate for patients without chemotherapy (44.44%) was higher than that with chemotherapy (6.67%), P<0.05. 4. Positive margin status was associated with
    local recurrence (P=0.0013). 5. Age at diagnosis of Patient with breast cancer (<40 years ), node-positive , grade 3
    
    
    histology were all highly significant factors of metastasis (p<0.05). The results showed that radiotherapy must be given after BCT; the patients with positive margin should be treated by reexcision or by mastectomy; the patients with young age,node-positive and grade 3 should receive adjuvant chemotherapy.
