- BACKGROUND: Surgical strategy in patients with thyroid cancer (TC) infiltrating the aerodigestive system is controversial. This study was undertaken to examine the long-term results of cervical evisceration (CE).PATIENTS AND METHODS: Since 1995, 14 consecutive patients with advanced TC underwent total laryngectomy (LE, n = 6) or esophagolaryngectomy (ELR, n = 8). Patients with unusual thyroid neoplasms or metastases to the thyroid (n = 3) were excluded. For esophageal reconstruction, free jejunal grafts (n = 6) and gastric tubes (n = 2) were used.RESULTS: Procedure-related morbidity and mortality were 42% and 14%, respectively. ELR was associated with a significant higher frequency of complications and reoperations compared with LE. Twelve-month and 30-month survival rates were 73% and 55%, respectively; 85% of the patients were satisfied with the surgical results. There were no long-term problems concerning food intake in the ELR patients. Two ELR patients were able to learn a substitutive voice.CONCLUSIONS: Cervical evisceration in patients with TC is associated with significant perioperative morbidity and mortality requiring careful patient selection. Regarding long-term survival, local tumor control, and patient's satisfaction, however, CE should be taken into account in suitable patients with advanced TC.

- Background. More than 90% of M918T carriers with multiple endocrine neoplasia type 2B (MEN 2B) harbor de novo mutations in the REarranged during Transfection (RET) protooncogene. DNA-based screening for RET germline mutations is rarely useful for early diagnosis, which thus is contingent on the clinical ascertainment of MEN 2B-specifitc symptoms as soon as they emerge. Little information exists about the presence of these symptoms in infancy.Methods. Detailed information was gathered regarding the development of MEN 2B-associated symptoms from the parents of 25 M918T RET carriers and 50 age- and sex-matched, controls with the use of a disease-specific questionnaire.Results. Until the end of the study, at a median age of 16 2 (range, 0.5-34.9 years), all 25 M918T RET carriers had developed medullary thyroid cancer. By that time, 96%, 91%, 71%, 75%, and 28% Of carriers displayed oral manifestations, ocular abnormalities, intestinal symptoms, musculoskeletal malformations, and pheochromocytoma, respectively. During the first year of life, fewer than 20% of carriers were found to express the typical MEN 2B phenotype, whereas 86% and 61% of these children, but none of the controls, were noted for their inability to cry tears and for constipation.Conclusion. Because the classic MEW 2B phenotype is rare during the first year of life, more emphasis should be placed on the more subtle features of the syndrome. Additional studies are needed to validate the usefulness of the symptoms "inability to cry" and "constipation" for earlier diagnosis of MEAT 2B.

- BACKGROUND: Hepatic metastases from medullary thyroid carcinoma (MTC) may impair quality of life by hypercalcitonemia-associated diarrhea and pain. In this prospective study, the effect of selective arterial chemoembolization (SACE) was evaluated.METHODS: Eleven patients with hepatic metastases from MTC received 1 to 9 courses of SACE using epirubicine. Symptomatic, biochemical, and morphologic responses on SACE were recorded.RESULTS: Symptomatic response was observed in all symptomatic patients. However, biochemical and radiologic response occurred only in 6 patients. Liver function was not affected by SACE. One patient with unexpected concurrent pheochromocytoma metastases died after the first course. Development of side effects in the course was observed in 8 patients but were only World Health Organization grade 1. Patients' satisfaction with SACE was excellent. Long-term follow-up found 7 patients alive (1-72 months). Three patients died with tumor 6, 12, and 24 months after SACE, respectively.CONCLUSION: SACE provided good symptom palliation for the majority of patients with hepatic metastases from MTC. However, transient remission or stabilization of hepatic metastases resulted in only 60%. Further studies using a randomized protocol are required.

- BACKGROUND: Techniques for autofluorescence have been introduced to visualize the parathyroid glands during surgery and to reduce hypoparathyroidism after thyroidectomy. METHODS: This parallel multicentre RCT investigated the use of Fluobeam® LX to visualize the parathyroid glands by autofluorescence during total thyroidectomy compared with no use. There was no restriction on the indication for surgery. Patients were randomized 1 : 1 and were blinded to the group allocation. The hypothesis was that autofluorescence enables identification and protection of the parathyroid glands during thyroidectomy. The primary endpoint was the rate of low parathyroid hormone (PTH) levels the day after surgery. RESULTS: Some 535 patients were randomized, and 486 patients received an intervention according to the study protocol, 246 in the Fluobeam® LX group and 240 in the control group. Some 64 patients (26.0 per cent) in the Fluobeam® LX group and 77 (32.1 per cent) in the control group had low levels of PTH after thyroidectomy (P = 0.141; relative risk (RR) 0.81, 95 per cent c.i. 0.61 to 1.07). Subanalysis of 174 patients undergoing central lymph node clearance showed that 15 of 82 (18 per cent) in the Fluobeam® LX group and 31 of 92 (33 per cent) in the control group had low levels of PTH on postoperative day 1 (P = 0.021; RR 0.54, 0.31 to 0.93). More parathyroid glands were identified during operation in patients who had surgery with Fluobeam® LX, and fewer parathyroid glands in the surgical specimen on definitive histopathology. No specific harm related to the use of Fluobeam® LX was reported. CONCLUSION: The use of autofluorescence during thyroidectomy did not reduce the rate of low PTH levels on postoperative day 1 in the whole group of patients. It did, however, reduce the rate in a subgroup of patients.
