Evidence mapping and quality assessment of systematic reviews on therapeutic interventions for oral cancer

Abstract

There is limited available evidence on treatments for oral cancer. The methodological quality of most included SRs scored "Critically low". The main beneficial treatment reported by authors for patients with resectable oral cancer is surgery alone or in combination with radiotherapy or chemotherapy. Evidence about the benefits of the treatments for unresectable oral cancer is lacking. These findings highlight the need to address future research focused on new treatments and knowledge gaps in this field, and increased efforts are required to improve the methodology quality and reporting process of SRs on treatments for oral cancer.
