Cancers of the oral cavity are one of the most common malignancies encountered
among cancer patients in India.1 There are different histological variants of oral
cavity cancers, and squamous cell carcinoma (SCC) is most common among them.
The main etiological factors implicated for development of oral cavity cancers are
tobacco chewing and alcohol use.2 In India, carcinoma of buccal mucosa has the
highest incidence among all the oral cavity cancers.3 The mean age of presentation
is 50 years.4 Incidence among males is three times that of females.5 Most of the
patients present in advanced stage (Stage III & IV) with majority in stage IV.6
Metastasis from oral cavity cancer takes place by detachment, invasion,
proliferation and evasion through lymphatic system and blood vessels. It is
regulated at various levels in the body.7 Most common sites of distant metastasis
from oral cavity cancers are lungs and liver. Sometimes vertebral bone metastasis
is also seen among patients. Metastasis to omentum and intra peritoneal organs
other than liver is very rare.
