Background Paclitaxel is wildly used in chemotherapy, however, the adverse drug reactions (ADRs) occurred frequently. Various novel nano-based paclitaxel delivery systems were developed. The aim performed systemically review and meta-analyses to evaluate the effect adverse drug reactions (ADRs) of paclitaxel and its nano-based delivery systems. Methods Systematically searched PubMed, Embase, Web of Science, Cochrane, Clinicalkey, Clinicaltrial.com, ASCO and ESMO. Data of adverse effect were analyzed to odds ratio (ORs) with 95% confidence interval (CI). The quality of studies was assessed with CASP Randomised Controlled Trial Checklist. Statistical analysis was used WinBUGS software (version 1.4.3) with the NetMetaXL interface (version 1.6.1). Results Twenty-one studies, including 7011 patients and 6 paclitaxel formulations fulfilled the inclusion criteria. In all grade hypersensitivity reactions, comparing to SB-P, people with Lip-P had 0.19 times (95% CI= 0.02, 1.3) of chance, with Nab-P had 0.47 times (95% CI= 0.11, 1.40) of chance, with PPX had 0.44 times (95% CI= 0.03, 5.7) of chance for all grade adverse effect. In All grad neutropenia, comparing to Lip-P, people with SB-P had 0.83 times (95% CI= 0.15, 4.81) of chance for all grade adverse effect; comparing to PM-P, people with SB-P had 0.73 times (95% CI= 0.22, 2.42) of chance for all grade adverse effect. In leucopenia, comparing to Nab-P, people with SB-P had 0.66 times (95% CI= 0.50, 0.87) of chance for all grade adverse effect; comparing to PM-P, people with SB-P had 0.64 times (95% CI= 0.32, 1.16) of chance for all grade adverse effect. The rate of incidence in peripheral sensory neuropathy, myalgias and arthralgias tend to no significant differences between different formulations. Conclusion Nano-based paclitaxel delivery resulted in fewer hypersensitivity reactions than solvent-based delivery. However, the incidence of neutropenia and leucopenia was higher in nano-based than solvent-based paclitaxel delivery. Dose-dependent ADRs were more frequent in paclitaxel anticancer treatment.
