肝脏罕见肿瘤的诊断和治疗
Diagnosis and treatment of rare hepatic tumors
目的 探讨肝脏罕见肿瘤的诊断和治疗方法.方法 回顾性分析我院2005年5月至2010年1月收治的25例肝脏罕见肿瘤患者的临床病理资料.结果 25例患者中肝局灶性结节性增生6例,肝血管平滑肌瘤、肝门部神经鞘瘤、肝左叶动脉瘤、肝胆管囊腺瘤、肝错构瘤、肝胆管绒毛状腺瘤、肝弥漫性大B细胞淋巴瘤各1例,肝血管平滑肌脂肪瘤2例,肝原发间质瘤2例,肝母细胞瘤5例,肝胚胎性肉瘤3例;术前行B超检查24例,CT检查22例,MRI检查6例,仅有3例(16.7%)检查和术后病理结果一致.术前诊断和术后病理符合5例(20%).25例均行手术切除治疗,包括半肝切除术7例,肝叶切除术7例,肝段切除术9例,肿瘤局部挖除2例.肝脏良性、低度恶性肿瘤及1例弥漫性大B细胞淋巴瘤术后无复发,5例恶性肿瘤随访中3例术后复发行再次手术切除,术后随访无复发;另2例死亡,平均术后生存期4个月.结论肝脏罕见肿瘤影像学诊断率低,手术切除是主要的治疗手段,对能切除的复发性肿瘤性病变应争取再次手术切除.
更多Objective To sum up our experience on the diagnosis and treatment of rare hepatic tumors. Methods The data of 25 patients with rare liver tumors admitted in our hospital from May 2005 to January 2010 were analyzed retrospectively. Results The final pathologic diagnosis of focal nodular hyperplasia was made in 6 cases, and the diagnosis of vascular leiomyoma, hilar neurilemoma, intrahepatic aneurysm, biliary cystadenoma, hepatic hamartoma, biliary villous adenoma, and hepatic diffuse large B-cell lymphoma was established in one each case, respectively. The diagnosis of angiomyolipoma in 2patients, primary liver gastroimestinal stromal tumor in 2 patients, hepatoblastoma in 5 patients and liver undifferentiated sarcoma in 3 patients was established. Preoperative ultrasonography, CT and MRI were performed in 24, 22 and 6 patients respectively. Preoperative tentative diagnosis was finally confirmed by pathology in only 3 (16.7%) cases, all by CT report. Preoperative diagnosis was consistent with postoperative pathology in 5 patients (20%); All patients underwent liver resection including hemihepatectomy in 7 patients, hepatic lobectomy in 7 patients, segmentectomy in 9 patients and tumor enucleation in 2 patients; There was no recurrence after resection of benign, low malignant tumors and hepatic diffuse large B-cell lymphoma; Postoperative follow-up was made for all the 5 cases of malignant tumours, and there was recurrence in 3 cases. These 3 eases underwent second resection and there were no recurrences after reoperation. The two recurrent patients died with a mean survival of 4 months.Conclusions The preoperative correct imaging diagnostic rate for rare hepatic tumors is low. Surgery is the most effective therapy and reoperation should always be attempted for tumor recurrence in order to prolong survival.
