摘要
目的探讨骶尾部畸胎瘤(SCT)复发原因及降低SCT复发率的合理治疗方案。方法回顾性分析12例复发性骶尾部畸胎瘤(RSCT)疗效。结果12例RSCT,其中良性7例,恶性5例,施行骶尾路手术切除9例,腹骶尾联合切除3例。5例行化疗。随访1～20年,存活9例,恶性SCT复发转移于术后10月内死亡3例。结论良性SCT复发主要原因是肿瘤和尾骨残留。恶性复发为瘤组织局部侵蚀,以及淋巴、血道转移。化疗可降低复发和死亡率。
Objective to study the cause of recurrent sacro coccygeal teratoma (RSCT)recurrence and to find an optimal therapy method,in order to decrease relapse rate of RSCT.Methods Efficacy of RSCT operation was retrospectively reviewed.Results7of the12cases RSCT Were benign,others weve malignant.9cases of RSCT weve resected by sacrococcygeal approach,3cases weve resected by abdomino sacroccygeal joint approach,5cases of malignant RSCT underwent chemotherapy.Follow-up for1～20years,9cases were survival.3case malignant were died from recurrence and mentastasis after10month.Conclusions The recurrent factors of benign RSCT were tumor and sacrum residual.Malignant RSCT recurrence were tumor mass infiltratio n and metastases via blood and lymph nodes Modern chemotherapy can decrease mortality and relapse rate.
