76例胰腺导管内乳头状黏液性肿瘤的外科治疗及预后分析

Surgical treatment of intraductal papillary mucinous neoplasms of the pancreas

目的 分析胰腺导管内乳头状黏液性肿瘤患者的临床特征及手术疗效.方法 收集1999年1月至2008年12月复旦大学附属中山医院手术切除的76例胰腺导管内乳头状黏液性肿瘤的病史资料,并进行随访,分析其临床特征及手术疗效.结果 76例患者中,男性49例,女性27例;肿瘤位于胰头者63例,胰体尾10例,全胰3例;32例为非浸润性肿瘤（腺瘤16例,交界性肿瘤6例,原位癌10例）,44例为浸润癌,两者在发病年龄及黄疸、消瘦、无症状患者、CA199升高等方面差异有统计学意义（P＜0.05）;胰十二指肠切除59例,联合门静脉切除重建4例,胰体尾切除6例,局部切除2例,节段性胰腺切除2例,全胰切除3例;总体并发症发生率为28.9%,无手术相关死亡病例;非浸润性及浸润性肿瘤患者5年生存率分别为100%及35%;非浸润性肿瘤患者7例切缘阳性,其中1例术后67个月复发转移;多因素分析显示肿瘤直径及淋巴结状况是影响浸润性癌患者预后的独立因素.结论 非浸润性胰腺导管内乳头状黏液性肿瘤手术疗效极佳,而浸润癌患者的预后较差;及早手术是防止病变进展及改善预后的关键;术后必须进行长期随访.

Objective To investigate the outcome of intraductual papillary mucious neoplasms （IPMN） of the pancreas after surgical resection. Method Clinical data of 76 patients with intraductal papillary neoplasms of the pancreas undergoing surgical resection at Zhongshan Hospital, Fudan University between January 1999 and December 2008 were retrospectively analyzed. Results Among the 76 patients,49 were male, 37 were female. 32 had noninvasive IPMNs, including adenomas（ n = 16）, borderline tumors （n =6 ）, carcinomas in situ （n = 10 ）. 44 had invasive IPMNs. Lesions were present in the head in 63 cases, in the body or tail in 10, in the whole pancreas in 3. There were significant difference in age,jaundice, weight loss, asymptomatic cases and CA199 value between noninvasive and invasive IPMNs.Three patients underwent total pancreatectomy, 59 patients underwent pancreaticoduodenectomy, 4 patients underwent pancreaticoduodenectomy with portal vein resection and reconstruction, six patients underwent distal pancreatectomy, two patients each underwent central pancreatectomy or enucleation. The overall postoperative morbidity rate were 28.9%, there was no operative mortality. Positive pancreatic margin was identified in seven patients of noninvasive neoplasms, among thoee one developed recurrence after 67 months. The five-year survival rate for patients with noninvasive and invasive neolpasms was 100% and 35% ,respectively. Size and lymph node metastasis were significant prognostic factors after surgical resection of the invasive IPMNs. Conclusions Surgical resection provides a favorable outcome for patients with noninvasive IPMNs. In contrast, invasive IPMNs was associated with a poor survival. Early resection is essential for improving survival. Long-term follow-up is necessary for all patients with IPMNs after resection.
