Minimizing Narcotic Analgesics After Endocrine Surgery

Thyroid CancerThyroid Nodule6 more

This research is being done to better understand and test if the investigators can minimize narcotic medication for controlling pain after thyroid or parathyroid surgery. This research will be performed at Doctors Hospital At Renaissance in the investigators clinic and the perioperative area. Participants will be randomly chosen to receive one of two options for pain management that the investigators are already using in the care of patients after surgery. One option includes a narcotic medication and one option includes a non-narcotic and a narcotic as needed. Participants will be asked to complete a form about the level of pain and how much pain medication was needed after surgery in the hospital and while at home. Participants will not have to do any additional visits to participate in this study. The investigators will obtain the research materials at the same time as the usual care visits around the participants' surgery.

Effect of Thyrotropin Level on Iodine Uptake in Metastatic Differentiated Thyroid Cancer

Differentiated Thyroid Cancer

Distant metastases is the leading cause of differentiated thyroid cancer-related death. Radioactive iodine (RAI) treatment is the most effective therapy for RAI-avid metastatic differentiated thyroid cancer (DTC). It is well known that the efficacy of RAI therapy is depend on the sodium-iodide symporter protein, which can be synthesized by elevated thyrotropin stimulation. Therefore, thyrotropin stimulation before RAI treatment to ensure sufficient uptake of RAI has been a long-established procedure. According to some observational studies, thyrotropin of 25-30 μIU/mL has been adopted as the standard care protocol. However, whether thyrotropin of 25-30 μIU/mL is enough to stimulate iodine uptake in metastatic lesions remains unknown. In this study, the investigators aim to address the effect of thyrotropin on iodine uptake in metastatic DTC during levothyroxine withdrawal by two times 124I PET/CT scans on different endogenous thyrotropin levels.

Fascial Versus Standard Neck Dissection in Patients With N1b Papillary Thyroid Carcinoma

Patients With Papillary Thyroid Cancer and N1b Status

Optimal surgical technique for neck dissection (LND) in thyroid carcinoma remains a subject of debate. Fascial ND (FND) implies the removal of the superficial and middle layers of the deep cervical fascia en bloc with lymph-nodes containing fibro-fatty tissue (levels IIa-Vb and VI-VII for cN1b patients). This retrospective cohort study was designed to compare FND with standard, non-fascial, selective ND (SND).

Study of Molecular Pathways in Medullary Thyroid Carcinoma and Correlation of Molecular Data With...

Medullary Thyroid CarcinomaMultiple Endocrine Neoplasia Type 2

Background: Medullary thyroid carcinoma (MTC) is a rare malignancy, occurring either as a sporadic disease (75% of cases), or in a hereditary pattern as multiple endocrine neoplasia (MEN) type 2 (MEN2A or MEN2B) or familial medullary thyroid carcinoma (FMTC). The MTC arises from the neural crest C-cells and in hereditary cases the first pathological disorder is C-cell hyperplasia (CCH) Most patients with MTC have advanced disease at the time of diagnosis. Chemotherapy and external beam radiotherapy have been minimally effective. Molecular targeted therapeutics (MTTs) and other receptor kinases in patients with advanced MTC have demonstrated activity. Despite some clinical responses, the collection of tumor tissues and autologous normal tissues has been virtually non-existent. Thus, laboratory studies defining affected molecular targets and downstream pathways, and molecular data providing direction for future clinical trials has yet to occur. Data from molecular studies of tumor tissue of hereditary or sporadic MTC patients will assist in predicting clinical behavior and the biology of MTC in predicting response to a given MTT, and in designing combination clinical trials. Objectives: Clarify how normal molecular pathways are altered by mutations in the RET protooncogene. Including additional genetic mutations and unidentified chromosomal translocations. Correlate results from molecular analyses of MTC tissue with patient s clinical course. Define how the molecular and clinical data will be useful in designing targeted therapy for patients with MTC. Eligibility: Patients must have confirmed diagnosis of C-cell hyperplasia, primary MTC, or metastatic MTC with archived pathology specimens available at Washington University. Design: Paraffin blocks of MTC tissues from archival samples at Washington University Department of Pathology will be selected. H&E slide from selected tissue blocks will be examined for molecular study suitability. Necessary tissue samples from blocks will have molecular studies, including, gene arrays, array comparative genomic hybridization, immunohistochemistry, and sequencing. Retrospective chart review will occur to obtain relevant clinical information.

Comparative Study of Surgical Completeness After Robotic Thyroidectomy Versus Conventional Open...

Papillary Thyroid Carcinoma

The robotic thyroidectomy (RT) has excellent cosmetic and several functional results. But there were no definite evidence of oncological safety of robotic thyroidectomy yet. To assure the surgical completeness of robotic thyroidectomy, the investigators compared robotic thyroidectomy and conventional open thyroidectomy (OT) by means of the postoperative radioactive iodine (RAI) uptake of possible remnant thyroid tissue and stimulated TG level.

Subcuticular Suture Versus Synthetic Glue in Thyroidectomy Incision

GoiterThyroid Neoplasms1 more

The aim of this study is to compare aesthetic results of two different type of sutures (subcuticular versus synthetic glue) in post-thyroidectomy incisions. It is a randomized clinical trial (single blinded) designed as a superiority study, since in the authors' hypotheses glue can give better results compared with subcuticular suture in this particular district. Secondary objective is to investigate if other factors (like the use of cold/warm blade, the sex, the presence of diabetes, the lenght of incision) can influence aesthetic results.

OnT4-Thyroglobulin Assay Before rhTSH-Aided Radioiodine Ablation

Differentiated Thyroid Carcinoma

Thyroidectomy followed by administration of large activities of 131-iodine (131I) is the treatment of choice for differentiated thyroid carcinoma (DTC). The serum thyroglobulin (Tg) measurement during hypothyroidism (offT4-Tg), just before radioiodine thyroid ablation, has proved to be effective for predicting persistent/recurrent disease. However, the Tg measurement cannot be used as a corresponding value for preablative offT4-Tg when rhTSH is used as stimulous before treatment. The present study was undertaken to evaluate if post-thyroidectomy Tg values, measured before rhTSH-stimulation and radioiodine administration, is of prognostic value in patients affected by DTC. We enrolled 28 patients with DTC and submitted to total thyroidectomy. Thyroxine (T4) treatment was started just after surgery to suppress TSH levels. Six to nine weeks later Tg levels were measured both basally (onT4-Tg) and after rhTSH (rhTSH-Tg) stimulation. Subsequently, T4 was stopped and serum Tg measured (offT4-Tg) just before 3700 MBq of 131I-iodide administration. A post-treatment whole body scan (PT-WBS) was performed and neck radioiodine uptake (RAIU) measured. A significant relationship was found between onT4-Tg and both rhTSH-Tg and offT4-Tg. The onT4-Tg levels of 0.2 ng/mL or higher predicted PT-WBS results with a 100% negative and 43% positive predictive values, respectively. Additionally onT4-Tg levels of 0.9 ng/mL or more predicts 12-months recurrences with 100% negative and 60% positive predictive value. In comparison, 1.0 ng/mL or higher offT4-Tg values predicted PT-WBS results and 12-months restaging with 94% and 100% negative and 45% and 27% positive predictive value, respectively. Basing on our data we conclude that preablative onT4-Tg may be of value as prognostic marker when rhTSH-aided radioiodine ablation is done. Additionally, the role of preblative onT4-Tg measurement as a yard-stick for radioiodine ablation should be further evaluate.
