Composite resections for oral cancers--experience with 97 consecutive cases.

Area of Science:

• Oncology
• Surgical Oncology
• Oral Cancer Research

Background:

• Oral cancers are frequently diagnosed at advanced stages (T3/T4).
• Tobacco addiction is a significant risk factor, present in all documented patients.
• Composite resections are a common surgical approach for these advanced oral cancers.

Purpose of the Study:

• To evaluate the effectiveness and value of radical ablation in treating oral cancers.
• To analyze prognostic factors influencing patient outcomes after surgery.
• To review the outcomes of various reconstructive techniques used in composite resections.

Main Methods:

• Retrospective analysis of 97 patients who underwent composite resections for oral cancer.
• Data collected from 1980-1982 at Tata Memorial Hospital's Head & Neck Unit 'C'.
• Review of patient records, including surgical procedures, histology, clinical and pathological nodal findings, and recurrence patterns.

Main Results:

• Squamous carcinoma was the predominant histologic type.
• Buccal mucosa and lower alveolus were the most common sites for lesions.
• A significant discrepancy was noted between clinical and pathological nodal staging.
• The final pathological 'N' status emerged as the most critical prognostic determinant.
• Most recurrences (local) occurred within 12 months of surgery.

Conclusions:

• Radical ablation remains a valuable treatment modality for advanced oral cancers.
• Accurate pathological nodal staging is crucial for predicting patient prognosis.
• Close follow-up is essential in the first year post-surgery due to the high rate of early recurrence.
