Management of Recurrent Well-Differentiated Thyroid Carcinoma in the Neck: A Comprehensive Review.

Surgery has been historically the preferred primary treatment for patients with well-differentiated thyroid carcinoma and for selected locoregional recurrences. Adjuvant therapy with radioactive iodine is typically recommended for patients with an intermediate to high risk of recurrence. Despite these treatments, locally advanced disease and locoregional relapses are not infrequent. These patients have a prolonged overall survival that may result in long periods of active disease and the possibility of requiring subsequent treatments. Recently, many new options have emerged as salvage therapies. This review offers a comprehensive discussion and considerations regarding surgery, active surveillance, radioactive iodine therapy, ultrasonography-guided percutaneous ablation, external beam radiotherapy, and systemic therapy for well-differentiated thyroid cancer based on relevant publications and current reference guidelines. We feel that the surgical member of the thyroid cancer management team is empowered by being aware and facile with all management options.

Facial nerve electrodiagnostics for patients with facial palsy: a clinical practice guideline.

PURPOSE: Facial nerve electrodiagnostics is a well-established and important tool for decision making in patients with facial nerve diseases. Nevertheless, many otorhinolaryngologist-head and neck surgeons do not routinely use facial nerve electrodiagnostics. This may be due to a current lack of agreement on methodology, interpretation, validity, and clinical application. Electrophysiological analyses of the facial nerve and the mimic muscles can assist in diagnosis, assess the lesion severity, and aid in decision making. With acute facial palsy, it is a valuable tool for predicting recovery. METHODS: This paper presents a guideline prepared by members of the International Head and Neck Scientific Group and of the Multidisciplinary Salivary Gland Society for use in cases of peripheral facial nerve disorders based on a systematic literature search. RESULTS: Required equipment, practical implementation, and interpretation of the results of facial nerve electrodiagnostics are presented. CONCLUSION: The aim of this guideline is to inform all involved parties (i.e. otorhinolaryngologist-head and neck surgeons and other medical specialists, therapeutic professionals and the affected persons) and to provide practical recommendations for the diagnostic use of facial nerve electrodiagnostics.

The surgical management of renal hyperparathyroidism.

Secondary and tertiary hyperparathyroidism (HPT) develop in patients with renal failure due to a variety of mechanisms including increased phosphorus and fibroblast growth factor 23 (FGF23), and decreased calcium and 1,25-dihydroxy vitamin D levels. Patients present with various bone disorders, cardiovascular disease, and typical laboratory abnormalities. Medical treatment consists of controlling hyperphosphatemia, vitamin D/analog and calcium administration, and calcimimetic agents. Improved medical therapies have led to a decrease in the use of parathyroidectomy (PTX). The surgical indications include parathyroid hormone (PTH) levels >800 pg/ml associated with hypercalcemia and/or hyperphosphatemia despite medical therapy. Other indications include calciphylaxis, fractures, bone pain or pruritis. Transplant recipients often show decreased PTH, calcium and phosphorus levels, but some will have persistent HPT. Evidence suggests that PTX may cause deterioration in renal graft function in the short-term calling into the question the indications for PTX in these patients. Pre-operative imaging is only occasionally helpful except in re-operative PTX. Operative approaches include subtotal PTX, total PTX with or without autotransplantation, and possible thymectomy. Each approach has its proponents, advantages and disadvantages which are discussed. Intraoperative PTH monitoring has a high positive predictive value of cure but a poor negative predictive value and therefore is of limited utility. Hypocalcemia is the most common complication requiring aggressive calcium administration. Benefits of surgery may include improved survival, bone mineral density and alleviation of symptoms.

Radiofrequency ablation of advanced head and neck cancer.

OBJECTIVE: To determine if the application of radiofrequency ablation to advanced head and neck cancer (HNC) would result in local control of the tumor. DESIGN: Radiofrequency ablation was applied to advanced head and neck malignant tumors in the participants of this nonrandomized controlled trial. SETTING: Academic tertiary care medical center. PARTICIPANTS: Twenty-one participants with recurrent and/or unresectable HNC who failed treatment with surgery, radiation, and/or chemotherapy were selected for the trial. Patients deemed appropriate for curative standard radiation or surgery were not accepted as participants. INTERVENTION: Radiofrequency ablation was applied to head and neck tumors under general anesthesia and computed tomographic scan guidance. MAIN OUTCOME MEASURES: The primary end point was local control. Computed tomographic scan tumor measurements were used to assess response by standard response evaluation criteria in solid tumors (RECIST) guidelines. Secondary outcome measures included survival and quality of life. RESULTS: Eight of 13 participants had stable disease after intervention. Median survival was 127 days, and an improvement in University of Washington quality-of-life scores was noted. Adverse outcomes included 1 death due to carotid hemorrhage and 2 strokes. CONCLUSION: Radiofrequency ablation is a palliative treatment alternative that shows promise in addressing the challenges of local control and quality of life in patients with incurable HNC who have failed standard curative treatment.
