Radiotherapy (RT) is an integral cancer treatment and RT utilization rates for commonly occurring carcinoma include breast: 87%, cervical: 71%, head and neck: 84%, lung: 77%, and prostate: 58% [1]. Overall, 57.5% of global head and neck cancers occur in Asia especially in India [2]. Head and neck cancers in India accounted for 30% of all cancers. In India, 60 to 80% of patients present with advanced disease as compared to 40% in developed countries [3]. Inequitable radiotherapy availability in India leads to non-compliance in many cases, as patients need to travel long distances for treatment. The number of functional radiotherapy units in India is below the limit recommended by the World Health Organization [3]. This poses a serious barrier to radiotherapy access as well as timely delivery of multidisciplinary cancer care.~Post operative radiation treatment for head and neck patients requires 6 weeks of time and the patient has to travel to the radiotherapy department daily for 5 days a week. This long course of radiation can lead to significant side effects resulting in some people being unable to complete the course of treatment. The Accelerate trial has potential to provide a quick solution (by reducing 30 fractions of PORT to 5 fractions) and is particularly suitable for resource constraint and overburdened radiotherapy. Five fractions of radiotherapy has been proven to be equally efficacious to long courses at various cancer sites like rectal cancer, breast cancer [4,5]. With small volume disease and technological advances in delivery of radiotherapy it is possible to deliver 5 fractions of hypofractionated RT to prostate, lung and pancreatic cancer [6-8].~The present study is a non -randomised phase II study that will enroll 50 patients and test feasibility of 30 Gy in 5 fractions of the primary disease and ipsilateral level I-III disease.~References~Atun R, Jaffray DA, Barton MB, et al: Expanding global access to radiotherapy.

The purpose of this research study is to investigate a shorter radiation treatment schedule for head and neck cancers. The present study is a non -randomized phase II study that will enroll 50 patients and test feasibility of 30 Gy in 5 fractions of the primary disease and ipsilateral level I-III disease.
