Head and neck cancers, Version 2.2014. Clinical practice guidelines in oncology.

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers focuses on glottic laryngeal cancer, which is the most common type of laryngeal cancer and has an excellent cure rate. The lymphatic drainage of the glottis is sparse, and early stage primaries rarely spread to regional nodes. Because hoarseness is an early symptom, most glottic laryngeal cancer is early stage at diagnosis. Updates to these guidelines for 2014 include revisions to "Principles of Radiation Therapy" for each site and "Principles of Surgery," and the addition of a new section on "Principles of Dental Evaluation and Management."

Mandibular Lytic Lesion in Familial Paraganglioma Syndrome Type I: A Clinical Conundrum.

OBJECTIVE: The entity of primary mandibular paraganglioma (PGL) is not well accepted within the head and neck. Mandibular PGLs hitherto reported in literature are malignant metastatic lesions, mostly from a pheochromocytoma. METHODS: We report a case of mandibular lytic lesion in a young female with multifocal PGLs but no family history of PGLs. We also performed a literature search to identify published cases of mandibular PGL. RESULTS: Lack of established criteria for malignancy in a PGL made diagnosis and treatment challenging. Testing was negative for a pheochromocytoma and positive for mutation of succinate dehydrogenase gene encoding subunit D (SDHD), thus rendering a diagnosis of familial PGL syndrome type I. Due to the absence of prior published reports of nonmalignant, primary mandibular PGL, patient was treated with surgery and postoperative radiotherapy. Our literature search revealed 4 published cases of mandibular PGL, all of which had an osteoblastic appearance and were malignant. CONCLUSIONS: Isolated mandibular PGL does not always indicate a malignant metastatic lesion. Genetic testing is recommended in patients with early onset of PGL and/or multifocality even without a positive family history. Surgical resection alone with surveillance can be offered for such isolated lesions in the presence of familial PGL syndrome type I.

Fasciocutaneous flap reconstruction of the tongue and floor of mouth: outcomes and techniques.

OBJECTIVES: To quantify functional and other outcomes after major resection and fasciocutaneous free-flap reconstruction of the tongue and floor of mouth, and to describe reconstructive technique. DESIGN: A hypothesis-generating, retrospective cohort study of 43 patients who underwent, at minimum, a hemiglossectomy and resection of the floor of the mouth for oral cancer followed by fasciocutaneous free-flap reconstruction. SETTING: A tertiary academic medical center in the midwestern United States. MAIN OUTCOME MEASURES: Speech intelligibility, swallowing, interval to decannulation, length of stay, free-flap success rates, patient survival, and complications. RESULTS: Thirty patients underwent oral tongue reconstructions, and 13, tongue base reconstructions. Median intelligibility scores were greater among patients in the tongue base group (98% intelligibility) than in the oral-tongue group (76% intelligibility) (P<.001). Of the 38 patients undergoing swallowing evaluation, 32 (85%) were able to feed entirely by mouth, most with mild to moderate dysphagia. All patients underwent decannulation (mean interval, 13.7 days). The mean length of hospital stay was 11 days, and free flaps in 42 patients (98%) survived. Twenty-eight patients (65%) were still alive by the end of the study, yielding a mean survival time of 27.4 months. Seven patients (16%) had severe medical and 3 (7%) had major surgical complications. CONCLUSION: The folding techniques used in this study for reconstruction of the tongue with fasciocutaneous free flaps were associated with recovery of adequate speech and swallowing in most patients.

Transoral resection of pharyngeal cancer: summary of a National Cancer Institute Head and Neck Cancer Steering Committee Clinical Trials Planning Meeting, November 6-7, 2011, Arlington, Virginia.

Recent advances now permit resection of many pharyngeal tumors through the open mouth, an approach that can greatly reduce the morbidity of surgical exposure. These transoral techniques are being rapidly adopted by the surgical community and hold considerable promise. On November 6-7, 2011, the National Cancer Institute sponsored a Clinical Trials Planning Meeting to address how to further investigate the use of transoral surgery, both in the good prognosis human papillomavirus (HPV)-initiated oropharyngeal cancers, and in those with HPV-unrelated disease. The proceedings of this meeting are summarized.
