肺叶切除术治疗妊娠滋养细胞肿瘤肺转移的疗效分析

目的 评价肺叶切除术治疗妊娠滋养细胞肿瘤(GTN)肺转移的疗效.方法 对1995年1月-2005年12月间北京协和医院收治的62例凶GTN肺转移行肺叶切除术患者的临床病理资料进行回顾性分析.根据术前临床治疗情况将上述患者分为复发性GTN(A组,10例)、耐药性GTN(B组,28例)和化疗过程中血清人绒毛膜促件腺激素β亚单位(β-hCG)水平呈对数下降、化疗效果满意但肺部病灶持续存在者(C组,25例),其中1例患者分别因耐药与复发两次接受肺叶切除术治疗,放同时进入A组和B组.结果 62例患者总的完伞缓解率为89%(55/62),其中A、B、C组完全缓解率分别为90%(9/10)、79%(22/28)和100%(25/25),B组明显低于C组(P=0.024),其他组间比较,差异则均无统计学意义(P>0.05).3组患者的复发率分别为2/8、15%(3/20)和0.3组高危[即国际妇产科联盟(FIGO)GTN评分≥7分]患者比例分别为90%(9/10)、82%(23/28)和44%(11/25),C组明显低于A、B组(P<0.05);B组患者术前化疗疗程数(7个疗程)明显多于A、C组(分别为3和5个疗程;P<0.05);A、B组患者术前血清β-hCG水平未达正常所占百分比[分别为50%(5/10)61%(17/28)]明显高于C组[为12%(3/25);P<0.05];而3组术后病理阳性率分别为60%(6/10)、36%(10/28)和12%(3/25),C组明显低于A、B组(P<0.05).结论 肺叶切除术对于GTN肺转移是一种有效的治疗方法 .对于肺部病灶相对局限的耐药和复发患者,建议在化疗后适时行肺叶切除术;而对于化疗过程中血清β-hCG水平呈对数下降、化疗效果满意而肺部病灶持续存在的初治患者,町严密随诊,暂不必选择手术治疗.

Pulmonary resection in the management of gestational trophoblastic neoplasia:a clinical study

Objective To investigate the effect of sumical resection in the management of gestafional trophoblastic neoplasia(GTN)patients with pulmonary metastases.Methods A retrospective review of the medical records of 62 GTN patients who underwent pulmonary resection was carried out.The cases were divided into recurrent group(group A,,l=10),drug-resistant group(group B,n=28),and the group with satisfactory response to chemotherapy but residual pulmonary lesion(s)(group C,n=25).One patient underwent lobectomy twice,and she was allocated simultaneously to groups A and B.The patients'median age,antecedent pregnancy,International Federation of Gynecology and Obstetrics(NGO)risk score,number of preoperative chemotherapy courses,preoperative β-human chorionic gonadotrophin (β-hCG)titer,lesion size,number of lobes affected,positive rate of histology,follow-ups and prognosis were compared between the three groups.Results The proportion of hish-risk patients in the three groups wag 90%,82%and 44%,respectively.The complete remission rates of the three groups were 90%,79%and 100%,with relapse mtes of 2/8,15%and zero,respectively.Positive histology of the resected specimen wasmore frequently recognized in recurrent and drug-resistant groups(A 60%,B 36%,C 12%).In the drug-resistant group there were more preoperative chemotherapy 8essiorls(A 3,B 7,C 5)and more patients with abnormal preoperative B-hCG titer(A 50%,B 61%,C 12%).Conclusions Surgical resection is effective in the treatment of pulmonary metastases of GTN.Surgery is indicated when clinical evidence suggests that pulmonary metastatic disease causes relapse or drug—resistance and the lesions arerelatively localized.Surgical resection is not recommended for patients with satisfactory response to chemotherapy but residual pulmonary lesions.
