Patients underwent curative surgical resection(C, 59%), non-curative surgery (NC, 12%), or nonsurgical treatment (NS, 28%). Median OS was 7.1, 1.4 and 1.9 years respectively(C vs. NC: p<0.001; C vs. NS: p=0.006; NC vs. NS: p=0.261). The physical well-being QOL differed over time (p=0.042) with greatest difference between C and NC surgery patients (p=0.049). The remaining QOL domain scores and pain scores demonstrated no significant time or treatment effect. For the 54 patients assessed from diagnosis, median OS was independently predicted by treatment group (C, NC, NS: 4.3, 1.7, vs. 2.4 years; p<0.001) and pain intensity (score ≤ 4vs. >4: 3.8vs. 2.0 years; p=0.001).
