Relationships of Selected Patient Characteristics with Overall Survival

		Univariate		Multivariate (n=86)
		HR (95% CI)	P-Value	HR (95% CI)	P-Value
BMI	Overweight/Obese vs. Normal/Underweight	1.18 (0.75, 1.86)	0.47	0.89 (0.53, 1.51)	0.67
Lost Weight	Yes vs No	1.43 (0.89, 2.29)	0.14	1.36 (0.77, 2.39)	0.29
Adjusted SKM Difference	Unit=1	0.95 (0.88, 1.03)	0.22	1.00 (0.93, 1.08)	0.94
Adjusted VAT Difference	Unit=1	0.97 (0.95, 0.99)	0.001	0.99 (0.97, 1.01)	0.46
Months on Treatment	Unit=1	0.90 (0.74, 1.09)	0.28	0.85 (0.68, 1.07)	0.17
Successful Resection*	Yes vs No	0.09 (0.05, 0.17)	<0.001	0.08 (0.04, 0.18)	<0.001

^*Only 55 patients had non-missing values for all specific surgery variables since patients had to have successful resection for tumor size or nodal status to be recorded. Therefore the models omit the specific surgical features in order to test the effect of surgery. Univariate and multivariate analyses which included tumor size, LN positivity, and surgical margin were performed for the 55 patients with complete data and none of these factors was significant (data not shown).
