Results
The median second progression-free survival was 24.2 months (95% confidence interval [CI] 17.7  35.2). The response rate after first- and second-line chemotherapy was 46.7% and 20%, respectively. The median overall survival was 35.2 months (95% CI: 27.8 to not reached). The main grade 3,4 adverse events were sensory neuropathy (18%), fatigue (10%), and anorexia (8%). There were no treatment-related deaths among patients administered the first-line and second-line regimens.

Participant flow
From May 2010 through March 2013, 52 patients from 10 institutions in the HCCSG were enrolled. Two patients, 1 who withdrew consent and 1 with no measurable lesion, were excluded from analysis. This, 50 patients were included in the efficacy analysis. All these 50 patients received first-line chemotherapy (SOX + Bmab). Second-line therapy (IRIS + Cmab, IRIS + Bmab, or IRIS) was administered to 20 patients (20%). Among the 20 patients, 12 patients received IRIS + Cmab and 8 patients received IRIS + Bmab. 
Adverse events
The main grade 3,4 adverse events were sensory neuropathy (18%), fatigue (10%), and anorexia (8%). There were no treatment-related deaths among patients administered the first-line and second-line regimens.
Outcome measures
The primary end-point of this study was the second progression-free survival (PFS), defined as the period from the date of enrollment to the date of either disease progression or death from any cause after second-line chemotherapy whichever came first. Secondary end-points were overall survival (OS), response rate (RR) after first- and second-line chemotherapy, the R0 resection rate (R0-rate), and adverse events.
