**5. Conclusions**

Oral cavity cancers are a diverse group of tumours which are known for its aggressive behaviour and higher chances of recurrences, which can lead to extremely difficult & cumbersome management decisions. This current review denotes the various available options for treatment for different categories of these tumours, to provide us a glimmer of hope to not only manage the disease well but also give good results in terms of locoregional control, long-term survival and at the same time ensuring cosmetically acceptable outcomes. As the primary focus of this chapter was on aspects of use of radiotherapy in oral cancers, the specific nuances on current evidence-based practice have been elaborated upon. Though most of the general details on use of external & internal radiation in oral cancers have been described, the detailed specific site-based & technique-based points have not been elaborated as they are beyond the scope of this chapter.

Available potential therapeutic options being currently investigated to ascertain possible benefit in oral cancers have also been described in this chapter. The future advances in use of radiation therapy should focus on recognising & refining the most appropriate indications for its application, strategic use of higher end technology like modulated arc therapy/stereotactic radiation & proton therapy, better amalgamation of radiation with newer concomitant systemic therapy agents as well as a well-rounded approach in inculcating genomic attributes of oral cancers in identifying the future standard of care for these tumours.
