RESUMEN
Context: As the number of head-and-neck cancer (HNC) patients are high in our subcontinent, the study was designed to reduce the treatment time and increase efficacy. Aims: Comparative evaluation of the efficacy, toxicity, local control, and survival of concomitant boost radiotherapy (CBRT), CBRT with concurrent chemoradiation (CBRT + CCT) and conventionally fractionated radiotherapy with concomitant chemotherapy (CFRT + CCT) in locally advanced HNC (LAHNC). Materials and Methods: Patients with LAHNC were randomly assigned to 3-groups of 30-patients each. Group I (CBRT) received, 45 Gy/25#/5-weeks and 18 Gy/10# concomitant boost in the last 2-week of treatment, receiving a total dose of 63 Gy. Group II (CBRT + CCT) received CBRT with concomitant cisplatin 75 mg/m 2 on day 1, 17, and 34. Group III (CFRT + CCT) received 64 Gy/32#/6.2 weeks, concurrent with injection cisplatin 75 mg/m 2 on day 1, 22, and 42. Statistical Analysis Used: Stata 9.0 SPSS and Chi-square test were used for analysis and disease-free survival (DFS) rates were calculated using the Kaplan–Meier method. Results: The median follow-up period was 8.2 months. At last follow-up, locoregional control was 36%, 57%, and 40% and DFS was seen in 33%, 53%, and 40% of patients in Group I, II, and III, respectively. Grade-3 cutaneous reactions were significantly higher in Group-II as compared to that of Group-III (P = 0.033) and Group-I (P = 0.715). Conclusion: All three groups have similar response rates and DFS with manageable toxicity
