背景胰腺导管内乳头状粘液性囊性肿瘤(IPMN)根据术后病理一般分为轻度异型性增生`、中度异型性增生、重度异型性增生、浸润性癌。非浸润性IPMN因有向浸润性癌发展的可能性,一般根据患者情况需手术切除治疗,但术后病理学常常提示切缘存在不同程度的异形性增生,关于切缘的阳性病理是否存在复发的危险目前仍有争议。此研究的目的是探索手术切缘异型性增生与复发率之间的关系。方法从MSKCC中心搜集行胰腺切除手术的病人,根据纳入
Background Pancreatic ductal papillary mucinous cystic neoplasms (IPMN) are generally classified as mild atypical hyperplasia, moderate atypical hyperplasia, severe atypical hyperplasia, and invasive carcinoma according to postoperative pathology. Non-invasive IPMN due to the possibility of invasive cancer development, the general situation of patients undergoing surgical resection, but postoperative pathology often prompted the existence of varying degrees of marginal heterotrophic hyperplasia, resection of the positive pathology of the existence of recurrence The danger is still controversial. The purpose of this study was to explore the relationship between atopic margin hyperplasia and recurrence rate. Methods Patients undergoing pancreatectomy were collected from the MSKCC center, according to inclusion
