Patients and methods
Patients with squamous cell carcinoma of oral tongue who had glossectomy treatment from 1987 to 1998 were recruited in the present prospective study. Patients with carcinoma of tongue base, other sites of oral cavity, or T4 stage were all excluded. Patients with excision biopsy prior to glossectomy were excluded because the tumor size could not be measured in the glossectomy specimen. One patient who died of the postoperative immediate complication of chest infection was also excluded because
Results
Nodal metastasis was present in 43 (51%) patients including 30 patients who had pathological evidence of nodal metastasis in the neck dissection specimens (9 therapeutic neck dissections for clinically N+ neck and 21 neck dissections for cN0 neck, 6 of them also had regional recurrences after neck dissections) and 13 patients who had nodal recurrences not associated with local recurrence (11 cN0 without elective neck dissection and 2 contralateral neck of pN0 patients after elective ipsilateral
Comments
Carcinoma of oral tongue is known to have high incidence of nodal metastasis even in the early T1 and T2 stages.12, 13 Nodal metastasis is in fact the most common site of recurrence and treatment failure of tongue carcinoma. The prognostic significance of tumor thickness in head and neck carcinomas had been reported consistently in the literature.3, 4, 5, 6, 7, 8, 9 Tumor diameter and T-staging were consistently found to be not significant prognostic factors in most reports.3, 4, 5, 6, 7, 8, 9

2022, International Journal of Oral and Maxillofacial SurgeryTransoral resection with buccinator flap reconstruction vs. pull-through resection and free flap reconstruction for the management of T1/T2 cancer of the tongue and floor of the mouth
2020, Journal of Cranio-Maxillofacial SurgeryCitation Excerpt :Even if pull-through surgery with free flap reconstruction and transoral surgery with buccinator flap reconstruction have the same oncological safety and transoral surgery has largely better functional results, it is important to underline that the small number of patients enrolled may bias our conclusions. Furthermore, good oncological results in transoral resection can be obtained only if resection is performed by expert surgical teams, and after careful clinical and, most importantly, radiological evaluation (Tagliabue et al., 2019; Yuen et al., 2000). This study reinforces the oncological comparability of the two techniques analyzed when “low risk” tumors staged as T1-T2 N0 involving the tongue and FOM are treated.
