摘要:Objective To investigate the clinical features,diagnosis and prognosis of solid pseudopapillary tumor of the pancreas(SPTP). Method The clinical data of SPTP cases that underwent surgical resection with a definitive histological diagnosis in Zhong Shan Hospital from 1999 to 2007 were retrospectively analyzed.Result There were 42 SPTP cases undergoing surgery in this period,including 37 females and 5 males:mean age was 37.6 years.Tumors located in the pancreatic head in 18 cases and in the body or tail in 24 cases.The most common symptom was abdominal discomfort(n=20),palpable mass (n=8).Preoperative diagnostic accuracy of MRI and CT were 93%and 31.8%,respectively.Ten cases underwent pancreaticoduodenectomy,20 cases received distal pancreatectomy,3 cases did spleen-preserving distal pancreatectomy.Tumors were simply enucleated in 8 cases.Average diameter of the tumors was 6.1 cm,34 lesions were solid,6 were solid-cystic,2 were cystic.The overall perioperative morbidity was 38.1%,10 cases developed postoperative pancreatic fistula.The mean follow-up time was 38.6 months.Except three cases that were lost to follow-up,all the other cases were alive.Four cases(2 cases had had tumor enucleation,2 had had distal pancreatectomy)developed hepatic metastases on 70、110、41、3 months after first surgery,respectively.A transarterial chemoembolization was employed in three cases,while right hemihepatectomy was performed in one case. Conclusion SPTP is an indolent tumor with low-grade biological aggressiveness.Patients had a favorable outcome after surgical treatment,but enucleation should be avoided.Patients with liver metastasis may benefit from chemoembolization and liver resection.%目的 总结胰腺实性假乳头状肿瘤的诊治及预后.方法 回顾性分析我院1999年1月至2008年4月手术切除的42例胰腺实性假乳头状肿瘤的临床特征、手术、病理情况及生存状况.结果 1999年1月至2008年4月我院共手术切除胰腺实性假乳头状肿瘤42例,其中,男性5例,女性37例;平均年龄37.6岁;胰头肿瘤18例,胰体尾24例;首发症状以腹痛最为多见(47.6%),28.6%患者无症状;MRI诊断正确率达93%(14/15);胰十二指肠切除10例,胰体尾加脾切除20例,肿瘤摘除术8例,保留脾胰体尾切除3例,节段胰腺切除1例;术后总并发症率38.1%,无再手术及围手术期死亡病例;肿瘤平均直径6.1 cm,34例实性肿瘤,6例为囊实性,2例为囊性;部分病例出现血管、神经侵犯;3例失访,其他均存活,平均随访时间38.6个月,其中4例术后出现肝转移,3例行介入栓塞治疗,1例行肝叶切除.结论 胰腺实性假乳头状肿瘤是一种好发于年青女性的低度恶性肿瘤,正规胰腺切除预后良好,应避免肿瘤摘除术;术后必须长期随访,如出现肝转移,采取介入栓塞或转移灶切除有较好的疗效.
