Identifying genetic markers for chemotherapy-induced peripheral neurotoxicity (CIPN) remains challenging due to inconsistent study findings. This review updates pharmacogenetic research on CIPN and suggests methods to improve future study reliability.
Area of Science:
- Pharmacogenetics
- Oncology
- Neuroscience
Background:
- Genetic variation influences drug response and adverse effects, including chemotherapy-induced peripheral neurotoxicity (CIPN).
- CIPN is a severe non-haematological adverse effect of cancer treatment, necessitating risk prediction strategies.
- Despite two decades of research, a reliable genetic profile for identifying high-risk CIPN patients is still lacking.
Purpose of the Study:
- To provide a critical update on the pharmacogenetics of CIPN, focusing on studies published since 2011.
- To highlight inconsistencies in current pharmacogenetic findings for CIPN.
- To discuss strategies for enhancing the reliability of future CIPN pharmacogenetic studies.
Main Methods:
- Literature review of pharmacogenetic studies on CIPN published since 2011.
- Critical analysis of methodological flaws and assessment tool reliability in existing studies.
- Synthesis of current knowledge and identification of research gaps.
Main Results:
- Existing pharmacogenetic data for CIPN is inconsistent, hindering the identification of high-risk patients.
- Methodological limitations and unreliable assessment tools contribute significantly to study inconsistencies.
- Recent research continues to explore genetic associations with CIPN, but definitive profiles are elusive.
Conclusions:
- A reliable genetic profile for predicting CIPN risk is an unmet clinical need.
- Improving study methodologies, including objective CIPN assessment, is crucial for advancing CIPN pharmacogenetics.
- Future research should focus on robust study designs to overcome current inconsistencies and establish predictive genetic markers.
