Continuous hyperfractionated accelerated radiotherapy in advanced head and neck malignancies.
58 patients of advanced head and neck cancer were treated by continuous hyperfractionated accelerated radiotherapy (study group) or conventional radiotherapy (control group). The study group of 29 patients had 26/29 (89%) of patients of stage T3 and T4 with 12/29 (41% 0) > N2 disease. The schedule employed was 1.5 Gy 3 times a day in 36 fractions on 12 treatment days without stopping for weekends. The spinal dose has been kept at 40.5 Gy and interfraction interval has been strictly kept at 6 hrs. Clinical, as well as radiological assessment has been encouraging with 23/29 (79.13%) of patients achieving complete regression of the primary tumor and nodal disease. Compared to the conventionally treated controls this value has been significant (P value < 0.001). In stage III disease tumor control has been in 9/10 (90%) cases, while in stage IV disease in 14/19 (73.68%) cases. The acute mucosal reactions have been found to be severe in these cases with 18/29 i.e. 62.06% suffering from grade III reactions. Nasogastric feeding was required in 25.92% of patients.
