Goshajinkigan for reducing chemotherapy-induced peripheral neuropathy: a systematic review and meta-analysis

Abstract

Background

Chemotherapy-induced peripheral neuropathy (CIPN) is common and presents with persistent and challenging symptoms for which there is no effective means of prevention. This systematic review assessed the efficacy and safety of Goshajinkigan in the prevention of CIPN.

Methods

A comprehensive literature search was conducted using Scopus, Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and ICHUSHI. Randomised controlled trials comparing Goshajinkigan with an alternative strategy for preventing CIPN were selected.

Results

Of five studies included in the review, Goshajinkigan did not reduce the risk of CIPN when the common terminology criteria for adverse events was used [risk ratio (RR) 0.94, 95% confidence interval (CI) 0.57–1.57 for grade ≥2 CIPN and RR 1.08, 95% CI 0.59–2.00 for grade ≥3 CIPN]. When the neurotoxicity criteria of Debiopharm was used, Goshajinkigan tended to decrease the risk of CIPN, but not significantly (RR 0.74, 95% CI 0.33–1.64 for grade ≥2 CIPN and RR 0.65, 95% CI 0.28–1.52 for grade ≥3 CIPN).

Conclusions

Goshajinkigan tended to prevent persistence but not severity of CIPN. Higher quality trials using multiple measures are needed in the future to clarify the preventive effect of Goshajinkigan and to assess the various aspects of CIPN.
