A randomized phase II study of continuous versus intermittent S-1 plus oxaliplatin in first-line treatment of patients with metastatic gastric carcinoma.
Journal of Clinical Oncology(2017)
Abstract
4028 Background: We conducted a randomized phase II study to compare continuous vs. intermittent S-1 + oxaliplatin (SOX) after induction of 6 cycles of SOX in patients (pts) with metastatic gastric cancer (MGC). Methods: Pts u003e18 yrs with chemo-naive MGC, normal organ function, ECOG PS 0-2, and measurable or evaluable lesion(s) were initially given an induction treatment of 6 cycles of SOX (S-1 40 mg/m2 bid on D1-14 + oxaliplatin 130 mg/m2 on D1 q 3 wks). Pts with CR/PR or SD were randomized to continue SOX (arm A) until progression/intolerable toxicity or discontinue until progression when SOX was re-administered (arm B). The primary endpoint was overall survival (OS), and secondary endpoints included progression-free survival (PFS), response rate, safety, quality of life, and biomarker correlative studies. Results: From July 2007 to Dec 2010, a total of 250 pts entered into the study. Median age was 53 yrs (range, 24-69); PS 0/1/2=13/219/18; M/F=162/88. Three pts did not receive treatment and 126 (50.4%)...
