2-year survival	Number of patients	Median (interquartile range)	Difference	95%CI	P value
CA 19-9 serum
Alive	8	98.6 (4.4-230.9)	135.9	-24.8 to 528.0	0.14
Dead	9	233.2 (114.4-890.4)	135.9	-24.8 to 528.0	0.14
CA 19-9 juice
Alive	8	24259.5 (884.2-91454.0)	275.7	-54112.8 to 63488.0	0.96
Dead	9	9932.0 (2073.6-88369.0)	275.7	-54112.8 to 63488.0	0.96
CEA serum
Alive	8	5.05 (2.1-11.2)	-2.2	-6.9 to 7.6	> 0.99
Dead	9	4.4 (1.9-10.5)	-2.2	-6.9 to 7.6	> 0.99
CEA juice
Alive	8	82.3 (71.2-230.6)	14.8	-175.04 to 124.5	0.92
