To evaluate the efficacy and safety of trastuzumab combined with chemotherapy in the treatment for HER-2-positive chemo-refractory advanced gastric or gastro-esophageal junction adenocarcinoma.
Twenty consecutive cases of chemo-refractory advanced gastric or gastro-esophageal junction adenocarcinoma treated in Peking University Cancer Hospital between 2009 June and 2013 August were included in this study. The patients with adenocarcinoma were previously confirmed and were eligible if their tumor showed overexpression of HER-2+++ by immunohistochemistry or HER-2 gene amplification-positive by FISH, and if they failed to at least one previous chemotherapy. Response and toxicities were evaluated with RECIST 1.0 and CTC AE 3.0 criteria.
The twenty patients received trastuzumab plus second- or later-line chemotherapy, consisting of nine platinum with fluoropyrimidines, five paclitaxel with fluoropyrimidines, three fluoropyrimidines monotherapy, two irinotecan monotherapy, and one docetaxel monotherapy. In these 20
