Summary
Marginal mandibulectomy is a safe and effective surgical option for oral cavity cancers, particularly those affecting the gingival buccal complex. This procedure offers good local control and disease-free survival rates in carefully selected patients.
Area of Science:
- Oncology
- Surgical Oncology
- Oral and Maxillofacial Surgery
Background:
- Oral cavity cancers, especially squamous cell carcinomas of the gingival buccal complex, pose significant treatment challenges.
- Surgical resection remains a cornerstone of treatment for these malignancies.
- Marginal mandibulectomy is a surgical technique involving the removal of a portion of the mandible.
Purpose of the Study:
- To evaluate the oncological outcomes of marginal mandibulectomy for oral cavity cancers.
- To specifically assess the efficacy of this procedure for squamous cell cancers of the gingival buccal complex.
Main Methods:
- A retrospective review of 107 patients who underwent marginal mandibulectomy between 1994 and 2001 was conducted.
- Data analysis focused on local failure rates, disease-free survival, and local recurrence-free survival.
Main Results:
- Eighty-three procedures were performed for gingivo-buccal complex cancers.
- The local failure rate was 16%.
- Two-year and five-year disease-free survival rates were 69% and 60%, respectively, with local recurrence-free survival rates of 79% and 70% at 2 and 5 years, respectively.
Conclusions:
- Marginal mandibulectomy can be an oncologically safe procedure when applied to carefully selected patients.
- The technique facilitates effective local control for oral cavity cancers.
