Objective: Head and Neck Squamous Cell Carcinoma (HNSCC) is one of the most frequent cancer sites around the globe. Within the heterogeneous group of HNSCC, Oral Squamous Cell Carcinoma (OSCC) deserves the utmost attention as an important subsite. Despite multimodality management, recurrence of OSCC is not uncommon. RT may play an integral role as part of initial management or as adjunctive therapy, or for treatment of recurrent disease. In this study, we evaluate multimodality imaging-based RT treatment volume definition for irradiation of recurrent OSCC.

Materials and methods: Multimodality imaging-based RT treatment volume definition for radiotherapeutic management of recurrent OSCC was assessed. RT target volume determination by incorporation of Magnetic Resonance Imaging (MRI) or by Computed Tomography (CT)-simulation images only has been evaluated and comparative analysis has been performed for patients receiving salvage RT for recurrent OSCC.

Results: Ground truth target volume has been found to be identical with treatment volume definition by CT-MR fusion-based imaging. 

Conclusion: Incorporation of MRI in target and treatment volume definition may improve target and treatment volume definition for recurrent OSCC.
