title: [Clinical features and prognosis of intraductal papillary mucinous neoplasms of pancreas: analysis of 38 cases].
abstract: OBJECTIVE
  To explore the diagnosis, clinical manifestation, treatment, and prognosis of intraductal papillary mucinous neoplasms (IPMNs) of pancreas.
  
  
  METHODS
  The clinical data of 38 patients with IPMNs, 23 males and 15 females, aged 64.1 +/- 10.7 (41 - 81), were analyzed respectively.
  
  
  RESULTS
  The main symptoms included abdominal pain and jaundice. Pancreaticoduodenectomy was performed on 32 patients, total pancreatectomy on 1 patient, distal pancreatectomy on 3 patients; and pancreatic biopsy on 2 patients. One patient died during the peri-operational period. Pathology showed 15 cases of main-duct type, 14 cases of branch-duct type, 1 case of mixed type, and 8 cases being un-differentiated, all with dilatation of pancreatic duct at different degrees 4.6 mm in diameter on average. There were 30 cases of invasive IPMNs, with significantly higher level of carbohydrate antigen 19-9 (CA19-9), and 8 non-invasive. The median survival time was 18.5 months in general. In the invasive IPMN group the general median survival time was 16.1 months, and the 1, 2, and 5-year survival times were 54%, 31%, and 21% respectively; and in the non-invasive IPMN group the median survival time was 24.3 months, and the 1, 2, and 5-year survival times were 58% and 38% respectively; without significant differences in the survival times between these 2 groups. TMN staging showed 6 cases of stage 0, 15 cases of stage I, 9 cases of stage II, and 4 cases of stage III among the 34 patients of malignant IPMNs. The median survival times of the patients of the stages 0, I, II, and III were 31.3, 27, 9.1, and 8.9 months respectively with significant differences among them (P = 0.0124).
  
  
  CONCLUSIONS
  IPMN of pancreas has no specific clinical manifestation. Dilatation of pancreatic duct is a manifestation in imaging examination characteristic of IPMN. The serum CA19-9 level is significantly higher in the patients with invasive IPMN. There are significant differences in survival rate among different groups according to TMN staging.
