Background: Cisplatin is widely used as radio sensitizer in head and neck cancer (HNC) and carcinoma cervix (CaCx). This study aims to see comparative nephrotoxicity of cisplatin in HNC and in CaCx without obstructive uropathy treated by concurrent chemoradiotherapy (CCRT). Materials and Methods: Fifty patients of HNC and 50 patients of CaCx stage II/III without obstructive uropathy were included in this study. Cisplatin 50 mg intravenous weekly was given before EBRT with adequate hydration and premedication in both groups. Before chemotherapy; blood urea, serum creatinine, and glomerular filtration rate (GFR) were measured. GFR was measured using 99m Tc diethylene triamine pentacaetic acid (DTPA) renogram study. Results: At the end of 4 th week, blood urea level 41-45 mg% was in 40 and 4% in HNC and CaCx, respectively (P = 0.018). At the end of 3 rd and 4 th week, blood urea level >45 mg% was 10 and 6% in HNC cases, respectively. At the end of 4 th week, serum creatinine level 1.1-1.5 mg% was 50 and 8% in HNC and CaCx, respectively (P = 0.047). Serum creatinine level >1.5 mg% was 6, 8, and 22% in HNC at the end of 2 nd , 3 rd , and 4 th week, respectively. GFR <80 ml/min at the end of 4 th week was 14% in HNC and only 2% in CaCx. GFR <100ml/min was significant at the end of 4 th week (P = 0.04). Univariate analysis showed significant relation between reduced oral fluid intake and reduced GFR (P < 0.001). Conclusion: In HNC, during concurrent chemoradiation, as the 3 rd -4 th week is reached, oral mucosal reactions increase and affect oral intake which further add to the cisplatin-induced nephrotoxicity. In CaCx without obstructive uropathy, renal function impairment is less severe as oral intake of water and liquid is not much impaired.
