Abstract
Background: We performed a systematic review and meta-analysis of the risk of oral and gastrointestinal (GI) mucosal injury associated with ramucirumab.
Patients and methods: Eligible studies included randomized Phase II and III trials of patients with solid tumors on ramucirumab: describing events of stomatitis, diarrhea, GI perforation and GI hemorrhage.
Results: Our search strategy yielded 167 potentially relevant citations from Pubmed/Medline, CENTRAL Cochrane registry, European society of medical oncology meeting abstracts and American Society of Clinical Oncology meeting library. After exclusion of ineligible studies, a total of 11 clinical trials were considered eligible for the meta-analysis. The RR of all-grade stomatitis, diarrhea, GI perforation and GI hemorrhage were 1.62 (95% CI 1.31 – 2.00; p < 0.00001), 1.15 (95% CI 1.07 – 1.24; p < 0.0001), 3.29 (95% CI 1.54 – 7.04; p = 0.002) and 1.92 (95% CI 1.03 – 3.57; p = 0.04), respectively. The RR of high-grade stomatitis, diarrhea, GI perforation and GI hemorrhage were 2.72 (95% CI 1.76 – 4.19; p < 0.00001), 1.28 (95% CI 0.96 – 1.71; p = 0.09), 3.37 (95% CI 1.51 – 7.54; p = 0.03) and 1.26 (95% CI 0.79 – 2.01; p = 0.34), respectively.
Conclusions: Our meta-analysis has demonstrated that ramucirumab-based combination treatment is associated with an increased risk of high-grade stomatitis and GI perforation compared to control treatment.
