Evaluation of short-term effectiveness of eight targeted agents combined with chemotherapy for treating esophageal-gastric junction adenocarcinoma: A network meta-analysis.

This study aimed to evaluate the short-term effectiveness of eight targeted agents (ramucirumab, bevacizumab, rilotumumab, panitumumab, cetuximab, trebananib, trastuzumab, matuzumab) plus chemotherapy in esophageal-gastric junction adenocarcinoma (EGJA) by a network meta-analysis (NMA). PubMed, Embase, and Cochrane Library databases were systematically retrieved for randomized clinical trials (RCTs) concerning targeted agents plus chemotherapy in the treatment of EGJA. This NMA combined both direct and indirect evidence to evaluate odds ratio (OR) and to draw the surface under the cumulative ranking curve (SUCRA). In total 11 RCTs with 3649 EGJA patients (1907 patients treated with targeted agents plus chemotherapy were regarded as the case group, and 1742 patients with placebo plus chemotherapy were assigned into the control group) were enrolled in this study. Targeted agents in terms of stable disease (SD), partial response (PR), disease control rate (DCR), and overall response ratio (ORR) with the SUCRA values of 0.838, 0.807, 0.934, and 0.793, respectively. Cetuximab and trastuzumab, with the SUCRA values of 0.884 and 0.758, came on top as the best outcomes for treating EGJA in terms of progressive disease (PD) and complete response (CR). Cluster analysis results indicated that ramucirumab plus chemotherapy might be the optimal treatment for EGJA. Our findings indicated that ramucirumab plus chemotherapy might be the optimal treatment for EGJA amongst the nine treatment regimens, which provided clinical guidance for clinicians in the treatment of EGJA.
