Abstract:
Several recent pharmacogenetic studies have investigated the variability in both outcome and toxicity in cisplatin-based therapies. These studies have focused on the genetic variability of therapeutic targets that could affect cisplatin response and toxicity in diverse type of cancer including lung, gastric, ovarian, testicular, and esophageal cancer. In this review, we seek to update the reader in this area of investigation, focusing primarily on DNA reparation enzymes and cisplatin metabolism through Glutathione S-Transferases (GSTs). Current evidence indicates a potential application of pharmacogenetics in therapeutic schemes in which cisplatin is the cornerstone of these treatments. Therefore, a collaborative effort is required to study these molecular characteristics in order to generate a genetic panel with clinical utility.
Insights
Pharmacogenetics can personalize cisplatin cancer therapy by examining genetic variations. Studying DNA repair enzymes and Glutathione S-Transferases (GSTs) may improve treatment outcomes and reduce toxicity.
Area of Science:
- Pharmacogenetics
- Cancer Therapy
- Molecular Biology
Background:
- Cisplatin is a cornerstone chemotherapy agent used across various cancers, including lung, gastric, ovarian, testicular, and esophageal.
- Significant variability exists in patient response and toxicity to cisplatin-based therapies.
- Pharmacogenetic studies investigate genetic factors influencing drug efficacy and side effects.
Purpose of the Study:
- To review current pharmacogenetic research on cisplatin therapy.
- To focus on genetic variability in DNA reparation enzymes and Glutathione S-Transferases (GSTs) affecting cisplatin metabolism and toxicity.
- To highlight the potential clinical utility of pharmacogenetics in cisplatin-based treatment regimens.
Main Methods:
- Literature review of recent pharmacogenetic studies.
- Analysis of research focusing on genetic polymorphisms in DNA repair pathways.
- Examination of studies investigating Glutathione S-Transferases (GSTs) in relation to cisplatin metabolism.
Main Results:
- Genetic variations in DNA repair enzymes and GSTs are linked to cisplatin response and toxicity.
- These genetic factors influence how patients metabolize and respond to cisplatin.
- Evidence suggests pharmacogenetics can optimize cisplatin treatment strategies.
Conclusions:
- Pharmacogenetics holds significant potential for tailoring cisplatin chemotherapy.
- Further collaborative research is needed to develop a clinical genetic panel for cisplatin therapy.
- Personalized medicine approaches using pharmacogenetics can improve cancer treatment outcomes.
