Treatment of Buccal Mucosa Cancer at Stage III or Stage IV A

Locally advanced buccal mucosa cancer — Stage III or Stage IV A — presents a clinical situation where the choice and sequence of treatment modalities is critical and depends on the patient's response to initial therapy.

Clinical Scenario

At Stage III and Stage IV A, buccal mucosa cancer is considered locally advanced. Multiple treatment strategies are recognised for this stage, including surgical approaches, radiotherapy, concurrent chemo-radiotherapy, altered fractionation schedules, and induction chemotherapy followed by further definitive therapy. The appropriate path depends on disease response and clinical assessment.

Treatment Approach — Partial Overview

When disease progresses through an initial course of induction chemotherapy, the appropriate treatment direction shifts decisively. The complete structured regimen — including all applicable options, selection criteria, and clinical sequencing — is set out in the full protocol.

For locally advanced Stage (III–IV A), surgery followed by RT with or without chemotherapy, concurrent chemo-RT, altered fractionation RT schedules, induction chemotherapy, followed by surgery with or without RT are valid treatment options.

Patients who have progressive disease after 3-4 cycles of induction chemotherapy should be considered for palliative treatment only.
