The objective of the study was to evaluate the long term results of the sentinel node (SN) biopsy technique in the management of the clinically negative (N0) neck in patients with early oral squamous cell carcinoma (T1–T2). Patients with positive SN underwent neck dissection. A sentinel lymph node (SLN) biopsy was performed on 31 consecutive patients. Six of the 31 patients were upstaged by the results of the SLN biopsy. The SLN biopsy allowed the identification of node metastasis in 100% of the cases with a sensitivity of 100%, specificity of 100%, and negative predictive value of 100%. There was a mean follow-up of 59 months. The neck control rate was 100% in the SLN negative group and two SLN positive patients developed subsequent neck disease (neck control rate of 88%). One SLN patient presented at the follow-up with a second primary tumor, 18 months later treated successfully by chemoradiotherapy. The overall survival rate was 100% in both groups. The promising reported short-term results have been sustained by long term follow-up. Patients with negative SLN achieved an excellent neck control rate. The neck control rate in SN negative patients was superior to that in SLN positive patients, but not statistically different.

In the present series, advanced laryngeal carcinoma was never associated with positive SM nodes, whereas advanced hypopharyngeal carcinoma showed a trend in favor of paratracheal lymph node involvement.

HNSCC is a serious disease that often necessitates aggressive treatment. All patients who are medically eligible should receive curative treatment, without age being an exclusion criterion. Taking comorbidity into account, on the other hand, enables treatment options to be optimized.

Total thyroidectomy or hemithyroidectomy together with a total laryngectomy (TL) or pharyngo laryngectomy (TPL) for (pharyngo) laryngeal cancer often renders the patient hypothyroid and commits them to life-long thyroid hormone replacement. To determine the incidence of thyroid gland invasion (TG) in patients undergoing TL or TPL with total thyroidectomy (TThy) or lobectomy (HThy) for advanced laryngeal or hypo pharyngeal cancer and to assess predicative factors. Retrospective analysis of 35 patients from 2007 to 2010. Specimens were examined to determine the incidence of TG invasion and relevant predicative factors such as histological grade and subglottic extension. Pre-operative imaging was reviewed to assess for radiological evidence of TG invasion. TL and TThy was performed in 13 patients. TL and HThy was performed in four patients and TPL and TThy was performed in 18 patients. Surgery was performed for primary and recurrent cancer in 29 and six patients, respectively. Histological evidence of invasion of the TG was found in three patients. Relationship was found between TG invasion and subsite of primary carcinoma and the presence of subglottic extension. No relationship was found between TG invasion and patient's sex, stage of primary disease at surgery, degree of differentiation. In addition, no significant relationship was found between the presence of TG invasion and recurrent disease. Invasion of the TG in patients undergoing a TL or TPL is a rare event and limits the need for a TTHy in most cases.
