Introduction: The research objective was to systematically review evidence on neurotrophic tyrosine receptor kinase () gene fusion frequency in solid tumors.
Methods: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature review (SLR) was conducted of studies published from January 1987 to 2 January 2020. Selected studies were appraised for use in meta-analysis, with frequency reported as a point estimate with confidence intervals, to estimate gene fusion tumor incidence and prevalence.
