Abstract
Purpose: With relatively few direct comparisons among treatment options for previously treated advanced gastric cancer or gastroesophageal junction (GEJ) cancer, network meta-analysis (NMA) may inform evidence-based decision-making. Ramucirumab plus paclitaxel (RAM + PTX) is a preferred regimen in guideline recommendations. NMA of key outcomes may further characterize the relative clinical value of RAM + PTX.
Methods: A systematic literature review of randomized controlled trials of adult patients with previously treated advanced gastric/GEJ cancer informed a NMA which compared overall survival, progression-free survival, and discontinuations due to adverse events. Comparisons were reported relative to placebo/best supportive care (BSC) when possible, otherwise relative to RAM + PTX.
Results: The base-case NMA focused on second-line treatment only, from 19 of 28 studies identified. For overall survival, seven of 16 regimens were favorable relative to placebo/BSC, with RAM + PTX as the most favorable. For progression-free survival, five of 14 regimens were unfavorable relative to RAM + PTX. For discontinuations due to adverse events, two of 13 regimens were similar to placebo/BSC: ramucirumab monotherapy and fluorouracil; relative to RAM-PTX, all regimens were similar except ramucirumab monotherapy which was favorable and irinotecan + cisplatin which was unfavorable.
Conclusion: This NMA of trials of previously treated gastric/GEJ cancer suggests that RAM + PTX has one of the more favorable clinical profiles.
期刊介绍：
The Journal of Gastrointestinal Cancer is a multidisciplinary medium for the publication of novel research pertaining to cancers arising from the gastrointestinal tract.The journal is dedicated to the most rapid publication possible.The journal publishes papers in all relevant fields, emphasizing those studies that are helpful in understanding and treating cancers affecting the esophagus, stomach, liver, gallbladder and biliary tree, pancreas, small bowel, large bowel, rectum, and anus. In addition, the Journal of Gastrointestinal Cancer publishes basic and translational scientific information from studies providing insight into the etiology and progression of cancers affecting these organs. New insights are provided from diverse areas of research such as studies exploring pre-neoplastic states, risk factors, epidemiology, genetics, preclinical therapeutics, surgery, radiation therapy, novel medical therapeutics, clinical trials, and outcome studies.In addition to reports of original clinical and experimental studies, the journal also publishes: case reports, state-of-the-art reviews on topics of immediate interest or importance; invited articles analyzing particular areas of pancreatic research and knowledge; perspectives in which critical evaluation and conflicting opinions about current topics may be expressed; meeting highlights that summarize important points presented at recent meetings; abstracts of symposia and conferences; book reviews; hypotheses; Letters to the Editors; and other items of special interest, including:Complex Cases in GI Oncology: This is a new initiative to provide a forum to review and discuss the history and management of complex and involved gastrointestinal oncology cases. The format will be similar to a teaching case conference where a case vignette is presented and is followed by a series of questions and discussion points. A brief reference list supporting the points made in discussion would be expected.
