Oncological outcome following de-intensification of treatment for stage I and II HPV negative oropharyngeal cancers with transoral robotic surgery (TORS): A prospective trial

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing in India. There were estimated 38,691 new cases of oropharyngeal cancers in India in 2012 [1]. As compared to the developed countries, where the increase in the incidence of OPSCC is mainly attributed to the epidemic increase in the incidence of HPV infection, the leading cause of OPSCC in India is still caused due to exposure to tobacco and alcohol. The prevalence of HPV positivity in newly diagnosed cases of OPSCC in developed countries like USA is>60% [2,3].
