Capecitabine with radiation is an effective adjuvant therapy in gastric cancers

Table 4 Subgroup analysis for overall and recurrence-free survival

Subgroup	Variable	Categories/units	n	Overall survival		Recurrence-free survival
				HR (95% CI)	P-value	HR (95% CI)	P-value
Surgical margins = positive	Treatment	Chemo alone	21	1		1
		5FU-RT/XRT		0.47 (0.100–2.191)	0.3	1.58 (0.206-12.154)	0.7
Stage T3/4	Treatment	Chemo alone	66	1		1
		5FU-RT/XRT		0.65 (0.294–1.454)	0.3	0.78 (0.352-1.709)	0.5
Node positive	Treatment	Chemo alone	94	1		1
		5FU-RT/XRT		0.92 (0.404–2.081)	0.8	1.10 (0.489-2.482)	0.8

5FU-RT: 5-fluorouracil + radiation; XRT: Capecitabine + radiation; HR: Hazard ratio.
