Abstract
Background
Patients with unresectable pancreatic and biliary cancers sometimes need decompression due to obstruction of the gastrointestinal tract and/or biliary tract. The aim of this study was to determine the prognostic factors associated with an indication for palliative bypass surgery in patients with unresectable pancreatic and biliary cancers.
Methods
Between April 2005 and September 2011, 37 patients with unresectable pancreatic and biliary cancers underwent palliative bypass surgery. Prognostic factors were searched for among clinical characteristics, operation-related factors, and tumor-related factors using a prospective database.
Results
The median survival time (MST) of these patients was 4.6 months, with a 6-month survival rate of 40.5 %. A multivariate Cox proportional hazards regression analysis revealed that mGPS >2 was the only independent prognostic factor for bypass surgery. Patients with an mGPS of 2 had an MST of 1.7 months, and they had a significantly worse prognosis than mGPS 0–1 patients with an MST of 6.3 months.
Conclusions
The mGPS is useful for predicting survival after surgical decompression due to gastrointestinal obstruction in patients with unresectable pancreatic and biliary cancers. Patients with a poor mGPS may not be indicated for palliative bypass surgery.
