Abstract

Purpose

. The transoral robotic surgery is a newer modality being used in surgical treatment of early oropharyngeal cancer. The aim of this study is to assess the outcome of these cases in terms of two year disease free survival and overall survival.

Methods

Between July 2016 and September 2018, 58 patients suffering from early oropharyngeal cancer underwent transoral robotic surgery with neck dissection at a tertiary referral centre. 43 of them have completed two years follow up and were analyzed for disease free survival and overall survival. 41 patients had HPV analysis done .

Results

The surgical margins were positive in 9/43 patients ( 6 in upfront surgery and 3 in the salvage cohort). Adjuvant therapy was administered to 16/34 patients on account of either positive margins or multiple nodal metastasis. 88% patients were found to be HPV negative. The two year disease free survival for the upfront cohort was 88.2% and salvage cohort was 55.5%. The overall survival was 86.05%.

Conclusions

The study highlights good locoregional control and two year disease free survival in HPV negative oropharyngeal cancer undergoing robotic surgery. Additionally, a positive surgical margin and recurrence were the statistically significant variables influencing 2 year disease free survival. Trans oral robotic surgery is an excellent tool for early tumors of the oropharynx. The presence of a positive surgical margin is a grim sign for survival and has a significant impact on positive outcome.
