Joint practice guidelines for radionuclide lymphoscintigraphy for sentinel node localization in oral/oropharyngeal squamous cell carcinoma

Involvement of the cervical lymph nodes is the most important prognostic factor for patients with oral/oropharyngeal squamous cell carcinoma (OSCC), and the decision whether to electively treat patients with clinically negative necks remains a controversial topic. Sentinel node biopsy (SNB) provides a minimally invasive method of determining the disease status of the cervical node basin, without the need for a formal neck dissection. This technique potentially improves the accuracy of histological nodal staging and avoids over-treating three-quarters of this patient population, minimizing associated morbidity. The technique has been validated for patients with OSCC, and larger-scale studies are in progress to determine its exact role in the management of this patient population. This article was designed to outline the current best practice guidelines for the provision of SNB in patients with early-stage OSCC, and to provide a framework for the currently evolving recommendations for its use. These guidelines were prepared by a multidisciplinary surgical/nuclear medicine/pathology expert panel under the joint auspices of the European Association of Nuclear Medicine (EANM) Oncology Committee and the Sentinel European Node Trial Committee

Efficacy of diagnostic upper node evaluation during (salvage) laryngectomy for supraglottic carcinoma.

Contains fulltext : 80816.pdf (publisher's version ) (Closed access)BACKGROUND: The effectiveness of selective upper node dissection or inspection during laryngectomy for supraglottic squamous cell carcinoma was evaluated. These diagnostic procedures aimed to cause less morbidity than elective neck dissection in patients with a clinically N0 neck. METHODS: In 93 patients, 166 clinically N0 necks (73 bilateral and 20 contralateral) were evaluated. Lymph nodes at levels II and III were inspected or dissected and directly sent in for frozen section histopathology. This way, occult neck metastases were identified and treated by neck dissection. RESULTS: Occult neck metastases were identified in 19% of the examined necks (31/166). Regional recurrence rate in the postoperative N0 necks was 0%, and 10% in the postoperative N+ necks. CONCLUSIONS: Selective upper node dissection and inspection during laryngectomy reduced the need for an elective neck dissection with its morbidity in the clinically N0 neck. In addition, it selects the patients who need such extensive treatment
