Background. Chemotherapy-induced toxicities lead to therapy dose reduction or delay, affecting patient outcomes. This systematic review and meta-analysis evaluated the impact of relative dose intensity (RDI) on survival in adult patients with solid tumor cancer on nonadjuvant-based chemotherapy regimens. Methods. PubMed, Embase, and Web of Science databases were searched for peer-reviewed English journal articles or congress abstracts evaluating association between RDI and survival; observational studies, case series of [greater than or equal to] 20 patients, and clinical trials published between 2013 and 2020 were eligible. Meta-analyses were conducted to quantify the association between RDI levels and overall survival (OS) among studies reporting a hazard ratio (HR) for OS by similar tumor types, regimens, and RDI. Forest plots represented summary HR and 95% confidence interval (CI); Cochran's Q and [I.sup.2] tests evaluated study heterogeneity. Results. Overall, 919 articles were reviewed and 22 included; seven were eligible for meta-analysis. Significantly shorter OS at RDI Conclusion. The results suggested longer OS with RDI [greater than or equal to] 80% or [greater than or equal to] 85% for both regimens, indicating that management of toxicities across treatment modalities may contribute to maintenance of higher RDI and benefit survival for patients with advanced solid tumors.
