Comparing national practice versus standard guidelines for the use of adjuvant treatment following robotic surgery for oropharyngeal squamous cell carcinoma

摘要

BACKGROUND: Recent historical management of oropharyngeal squamous cell carcinoma typically includes radiotherapy with/without chemotherapy. Novel surgical techniques such as robotic surgery have made primary surgery more frequent; however, postoperative radiotherapy may be recommended. We aimed to assess adherence to guidelines for postoperative therapy following robotic surgery. METHODS: Using the National Cancer Database, we analyzed the frequency of radiotherapy following robotic surgery for cT1-3cN0-2cM0 squamous cell carcinoma of the oropharynx, specifically in the presence of widely accepted indications for postoperative radiotherapy and/or chemotherapy. RESULTS: Approximately two-thirds of patients received radiotherapy after robotic surgery for early-intermediate stage oropharyngeal cancer. One in five patients with an indication for adjuvant radiotherapy and 1/3 with an indication for adjuvant chemotherapy did not receive recommended adjuvant therapy. CONCLUSIONS: A high proportion of patients require radiotherapy after robotic surgery for early-intermediate stage oropharyngeal cancer. Patients with an indication for further adjuvant therapy commonly do not receive it.
