Oral cancers: Current status.

Oral cancer is a global disease. Despite a well elucidated tumour progression model, these cancers present late. Attempts at early detection by way of adjunctive diagnostic technologies and screening have not lived up to expectations in spite initial promise. Surgery is the mainstay of treatment. Treatment intensification by way of adjuvant radiation/chemo radiation is warranted for those with high risk features. Recent studies have explored intensification in those with intermediate risk factors in an attempt to improve outcomes. There has been generation of recent robust evidence that has influenced the need and extent of neck dissection. Neoadjuvant chemotherapy (NACT) may have a potential role in organ preservation and borderline resectable oral cancers. Recurrent tumours should be offered surgery whenever feasible while the addition of biological agents to chemotherapy gives best results in the palliative settings. [ABSTRACT FROM AUTHOR]
