Aim: Pulmonary toxicity is a well-known adverse reaction of bleomycin. In this study, we investigated the influence of XPC, PMAIP1/Noxa and TLR4 genetic variants on the development of bleomycin-induced lung injury (BILI) in south Indian patients with Hodgkin lymphoma. Materials & methods: Hodgkin lymphoma patients receiving adriamycin, bleomycin, vinblastine and dacarbazine regimen were recruited for the study and BILI was diagnosed based on symptoms and/or radiological signs. DNA samples were genotyped using real-time PCR. Results: A total of 78 patients were recruited in the study and BILI was observed in 17 (21.8%) patients. Polymorphisms in XPC, PMAIP1/Noxa and TLR4 genes were not associated with the development of BILI. Conclusion: The selected genetic polymorphisms do not predict the risk of BILI in south Indian population.
