CANCER RESEARCH AND TREATMENT (CRT)
Abstract Purpose The aim of this study was to verify prognostic factors including sarcopenia in patients with recurrent or metastatic pancreatic cancer receiving gemcitabine based chemotherapy. Materials and Methods
le
Medical records and computed tomography scan of consecutive patients treated with palliative gemcitabine based chemotherapy from 2008 to 2014 were reviewed. The lumbar
tic
skeletal muscle index at 3rd lumbar spine level was computed, and together with clinicolaboratory factors, univariate and multivariable analyses for overall survival (OS) were performed.

Results
A total of 88 patients were found. Median age was 65 years, and male patients were predominant (67.0%). Most patients had initially metastatic disease (72.7%), and gemcitabine

monotherapy was administered in 29 patients (33.0%) while gemcitabine plus erlotinib was administered in 59 patients (67.0%). Seventy six patients (86.3%) had sarcopenia. With a median follow-up period of 44.32 months (range 0.6-44.3 months), median OS was 5.35
