Malignant neoplasm of commissure of lip
ICD-10 C00.6 · ICD-11 2B6B.0.1

Treatment of Advanced-Stage (T3/T4) Lip Cancer at the Commissure

This protocol addresses larger, advanced-stage malignant neoplasms of the commissure of lip — tumours exceeding 4 cm in greatest dimension (T3 or T4) that require reconstruction.

Larger lesions of the lip require more consideration with regard to reconstruction techniques. Five-year crude survival rates for surgical treatment drop substantially at T3 and T4 staging compared with earlier-stage disease.

Post-Surgical Management

Following resection, adjuvant therapy directed at the operative site may be indicated. The full structured protocol specifies the criteria and approach for post-operative adjuvant treatment in the presence of unfavourable disease factors.

Full regimen details, sequencing, and decision criteria available via the protocol below.

Larger lesions of the lip require more consideration with regard to reconstruction techniques.

The five-year crude survival rates for surgical treatment are about 75–80 per cent for T1 to T2 tumours, dropping to 40–50 per cent for T3 and T4 tumours.

Post-operative adjuvant radiation or radiochemotherapy should be considered in the presence of unfavourable disease factors.
