Multivariate survival analysis¹

Factors	HR	p value	95% CI
Performance status 2	4.8	< .001	2.55–10.2
Pathologic por	3.50	.002	1.60–7.96
Peritoneal met	2.10	.009	1.20–3.68
LDH ≥ 400 (IU/L)	2.05	.019	1.13–3.74
PFS < 6 months	1.80	.040	1.08–3.01

¹Adjusted by gender, liver metastasis, metastatic sites, response to FOLFOX, cause of oxaliplatin discontinuation, leukocyte count, ALP, and CEA.

Abbreviations: CI = confidence interval; HR = hazard ratio; LDH = lactate dehydrogenase; met = metastasis; PFS = progression-free survival; por = poorly differentiated adenocarcinoma.
