Abstract
Modest survival rates are published for treatment of oral squamous cell carcinoma (OSCC) using conventional approaches. Few cohort studies are available for transoral resection of OSCC. Analysis for recurrence, survival, and prognosis of patients with OSCC treated with transoral laser microsurgery (TLM) ± neck dissection was obtained from a prospective database. Ninety-five patients (71 patients had stages T1-T2 and 24 had stages T3-T4 disease) with minimum follow-up of 24 months met criteria and demonstrated negative margins in 95%. Five-year local control (LC) and disease-specific survival (DSS) were 78% and 76%, respectively. Surgical salvage achieved an absolute final locoregional control of 92%. Immune compromise and final margins were prognostic for LC, whereas T classification, N classification, TNM stage, comorbidity, and perineural invasion were also significant for DSS. We document a large series of patients with OSCC treated with TLM, incorporating T1 to T4 primaries. A significant proportion of stage III/IV cases demonstrates feasibility of TLM in higher stages, with final margin positivity of 5%, LC greater than 90%, and comparable survival outcomes.
Highlights
Surgery performed with curative intent is a widely established treatment modality for oral cancer, with the addition of adjuvant therapy in advanced cases.[1]
One hundred fourteen cases of oral squamous cell carcinoma (OSCC) were identified in our transoral laser microsurgery (TLM) database
We document a series of OSCC treated with TLM and simultaneous neck dissection, when indicated
Summary
Surgery performed with curative intent is a widely established treatment modality for oral cancer, with the addition of adjuvant therapy in advanced cases.[1] within the gamut of head and neck cancer, surgical resection of oral squamous cell carcinoma (OSCC) poses unique therapeutic challenges because of the aggressive behavior of these tumors, and the potential for functional and esthetic deficits. These considerations promote a transition from the long-standing practice of transfacial or transcervical external composite resection to minimally invasive resections without compromising oncologic outcomes. A significant proportion of stage III/IV cases demonstrates feasibility of TLM in higher stages, with final margin positivity of 5%, LC greater than 90%, and comparable survival outcomes
