Table 5 Characteristics of GBC cancer
Category | Characteristic |
|---|---|
Epidemiological | High incidence in Southeast Asia, South-central China，Africa (high consumption area of betel nut) |
Clinical manifestation | (1) Large range of lesions (2) Patients with a history of mucosal disease: the depth of tumor invasion is shallow; patients with a history of betel nut chewing: the depth of lesion invasion is deeper |
Surgical features | (1) The concept of bone resection is consistent with gingival cancer (2) The concept of the buccal resection is the same as that of buccal cancer (3) The marginal mandibular branch of facial nerve is not considered to preserve for GBC cancer involving the mandible |
Prognosis | High recurrence and metastasis rate, poor prognosis |
Complication | Due to the insufficient thickness of the soft tissue covering the buccal, post-radiotherapy complications and hardware related complications are high, especially abnormal sensation and titanium plates exposure |
