PFS was defined as the time from the date of randomization to the date of the first documentation of progressive disease (PD) or date of death, whichever occurs first. For target lesions (TL), PD was defined as at least a 20 percent (%) increase in the sum of the longest diameter (SLD) of TLs, taking as a reference the smallest SLD recorded since the treatment started, or the appearance of one or more lesions. For non-target lesions (NTL), PD was defined as an unequivocal progression of existing NTLs. Participants were censored at the last date of tumor measurement, the last date in the study drug log, or the date of last follow-up.

Clinical benefit was defined as stable disease (SD), CR, or PR for 6 weeks or longer as determined by RECIST. For TLs, SD was defined as neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for PD, taking as a reference the smallest SLD recorded since treatment had started. For NTLs, SD was defined as a persistence of one or more NTLs and/or maintenance of tumor marker levels above the normal limits.

EORTC QLQ-C30: included functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting) and single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea and financial difficulties). Most questions used 4 point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score equals (=) better level of functioning or greater degree of symptoms.

EORTC Quality of Life Questionnaire-Stomach Cancer Specific (QLQ STO22) Questionnaire Scores

The QLQ-STO22 is a gastric cancer quality of life questionnaire. There are 22 questions concerning disease, treatment related symptoms, side effects, dysphagia, nutritional aspects, and questions about the emotional problems of gastric cancer (dysphagia, pain, reflux, eating restrictions, anxiety, dry mouth, body image, and hair loss). The questions are grouped into five scales and 4 single items which are related to the symptoms of the disease. Most questions used 4-point scale (1 'Not at all' to 4 'Very much'; 1 question was a yes or no answer). A linear transformation was used to standardize all scores and single-items to a scale of 0 to 100; higher score=better level of functioning or greater degree of symptoms.

Change in body weight was categorized as an increase of greater than (>)5 percent (%), no change (plus or minus [±]5%), decrease of >5-10%, or a decrease of >10% from BL to the end of study. Time windows were applied in order to assign visits to weight measurements, and the lowest post-screening value recorded was used for the analysis. The percentage change in weight from screening was summarized over time.

Summary
Brief summary
This parallel, randomized, open-label, multi-centre study will evaluate the effect on overall
survival of trastuzumab (Herceptin) in combination with a chemotherapy compared to the
chemotherapy alone in patients with HER2-positive advanced gastric cancer. Trastuzumab
(Herceptin) will be administered as intravenous infusion of 6 mg/kg (loading dose 8 mg/kg)
every 3 weeks. The chemotherapy consists of a combination of 6 cycles of fluorouracil (800
mg/m2/day intravenous infusion every 3 weeks) and cisplatin (80 mg/m2 intravenous infusion
every 3 weeks), or capecitabine (Xeloda, 1000 mg/m2 po twice daily for 14 days every 3 weeks)
and cisplatin (80 mg/m2 intravenous infusion every 3 weeks). Treatment with trastuzumab
(Herceptin) will continue until disease progression. The target sample size is 300-600
patients.
