Background Malignant mesothelioma (MM) is an asbestos related aggressive tumor with poor prognosis. The aim of this study was to investigate if aquaporin 1 (AQP1) genetic polymorphisms influence the risk of MM and the response to cisplatin based MM treatment. Patients and methods The case-control study included 231 patients with MM and a control group of 316 healthy blood donors. All subjects were genotyped for three AQP1polymorphisms (rs1049305, rs1476597 and rs28362731). Logistic and Cox regression were used in statistical analysis. Results AQP1 rs1049305 polymorphism was significantly associated with MM risk in dominant model adjusted for gender and age (OR = 0.60, 95% CI = 0.37-0.96, Padj = 0.033). This polymorphism was also significantly associated with cisplatin based treatment related anaemia (unadjusted: OR = 0.49, 95% CI = 0.27-0.90, P = 0.021; adjusted: for CRP: OR = 0.52, 95% CI = 0.27-0.99, P = 0.046), with leukopenia (OR = 2.09, 95% CI = 1.00-4.35, P = 0.049) in dominant model and with thrombocytopenia (OR = 3.06, 95% CI = 1.01-9.28, P = 0.048) and alopecia (OR = 2.92, 95% CI = 1.00-8.46, P = 0.049) in additive model. AQP1 rs28362731 was significantly associated with thrombocytopenia (unadjusted: OR = 3.73, 95% CI = 1.00-13.84, P = 0.049; adjusted for pain: OR = 4.63, 95% CI = 1.13-19.05, P = 0.034) in additive model. Conclusions AQP1 may play a role in the risk of MM. Furthermore, AQP1 genotype information could improve the prediction of MM patients at increased risk for cisplatin toxicity.
