Objective The aim of this study was to evaluate outcomes of the recurrent and non-recurrent groups including disease-specific mortality of patients with well-differentiated thyroid carcinoma after multimodality treatment. In addition, prognostic factors for disease-specific mortality were analyzed. Summary of Background Data Among 2,844, there were 166 patients with recurrent disease. Recurrent disease was defined as the presence of papillary or follicular thyroid cancer 6 months after the initial thyroidectomy, including locoregional or distant metastasis, diagnosed using diagnostic or therapeutic 131I scans or other imaging techniques. Methods The study was a retrospective analysis of prospectively collected data for a long-term follow-up result of well-differentiated thyroid carcinoma patients. Results The mean age of 166 patients was 45.8 ± 1.2 years, 116 (69.9%) were women, 111 (66.9%) had locoregional neck recurrence, and 55 (33.1%) had metastatic recurrence in distant organs. We found that when recurrences were observed, more than half were detected within the first 5 years following the initial therapy. The longest period of time before relapse was 29.8 years. After a mean follow-up period of 12.7 ± 0.5 years, 37 (22.3%) patients experienced disease-specific mortality. Multivariable analysis revealed that older age, male sex, and development of a second primary malignancy were associated with disease-specific mortality. Higher post-operative levels of thyroglobulin predicted a shorter time to relapse. Conclusions These data indicate that among the recurrent cases over 50% of recurrent well-differentiated thyroid carcinomas were diagnosed within 5 years after initial thyroidectomy. Additionally, more than 20% of the patients died of thyroid cancer.

Abstract Context Modern management of differentiated thyroid cancer requires individualized care plans that tailor the intensity of therapy and follow-up to the estimated risks of recurrence and disease-specific mortality. Design This summary is based on the authors’ knowledge and extensive clinical experience, supplemented by review of published review articles, thyroid cancer management guidelines, published staging systems, and original articles identified through a PubMed search, which included terms such as risk stratification, staging, clinical outcomes, and differentiated thyroid cancer. Main Outcome Measures In the past, risk stratification in differentiated thyroid cancer usually referred to a static estimate of disease-specific mortality that was based on a small set of clinicopathological features available within a few weeks of completing initial therapy (thyroidectomy, with or without radioactive iodine). Today, risk stratification is a dynamic, active process used to predict the appropriateness for minimalistic initial therapy, disease-specific mortality, risk of recurrence, and the most likely response to initial therapy. Rather than being a static prediction available only after initial therapy, modern risk stratification is a dynamic, iterative process that begins as soon as a suspicious nodule is detected and continues through final follow-up. Conclusions Dynamic risk assessment should be used to guide all aspects of thyroid cancer management, beginning before a definitive diagnosis is made and continuing through the final follow-up visit.

Most data on differentiated thyroid cancer (DTC) came from the Western world. We describe its salient characteristics and outcome from a Middle Eastern country.Patients and Methods. We studied all cases of TC seen during a 2-year period (2004-2005) seen at our institution.Results. A total of 600 consecutive cases of DTC with a median age at diagnosis of 39 years (5–85) and the female : male ratio of 459 : 141 (76.5% : 23.5%). The cases included classical papillary thyroid cancer (PTC) in 77%, follicular variant PTC in 13.3%, follicular thyroid cancer in 3.2%, and other rare subtypes 6.5%. Total or near-total thyroidectomy was performed in 93%, central and/or lateral neck dissection in 64.5% of cases, and radioactive iodine ablation in 82% of cases. Additional therapies were administered to 154 patients (25.7%). At a median follow-up period of 7.63 years (0.22–13.1), 318 patients (53.3%) were in excellent response, 147 (24.5%) having an indeterminate response, 55 (9.2%) biochemically incomplete, 33 (5.5%) structurally incomplete, and 27 (4.5%) unclassifiable. Twenty cases died secondary to DTC (disease-specific mortality 3.3%).Conclusions. In Saudi Arabia, DTC is common and occurs at young age and predominantly in females. Although remission is common, persistent disease is also common but disease-specific mortality is low.

Abstract Background Parathyroid carcinoma is a rare endocrine malignancy, rarer when synchronous with a non medullary well differentiated thyroid carcinoma. Parathyroid carcinoma accounts of 0.005% of all malignant tumors and it is responsible for less than 1% of primary hyperparathyroidism. The intrathyroidal localization of a parathyroid gland is not frequent with a reported prevalence of 0.2%. Carcinoma of parathyroids with intrathyroidal localization represents an even rarer finding, reported in only 16 cases described in literature. The rare constellation of synchronous parathyroid and thyroid carcinomas has prompted us to report our experience and perform literature review. Case presentation We herein report a case of a 63-years-old man with multinodular goiter and biochemical diagnosis of hyperparathyroidism. Total thyroidectomy with radio-guide technique using gamma probe after intraoperative sesta-MIBI administration and intraoperative PTH level was performed. The high radiation levels in the posterior thyroid lobe discovered an intrathyroidal parathyroid. Microscopic examination revealed a parathyroid main cell carcinoma at the posterior thyroidal left basal lobe, a classic papillary carcinoma at the same lobe and follicular variant of papillary carcinoma at the thyroidal right lobe. To the best of our knowledge, this is the first case documenting a synchronous multicentric non medullary thyroid carcinomas and intrathyroidal parathyroid carcinoma. Conclusions Our experience was reported and literature review underlining challenging difficulties in diagnostic workup and surgical management was carried out.

<p><strong><em>Background:</em></strong> Thyroid carcinoma is rare in childhood and adolescence. The presentation is more advanced in case of children as compared to adults. However, the prognosis for survival in children is reportedly excellent. The aim of the study was to see the outcome of patients with well differentiated thyroid carcinoma during childhood and adolescence treated at a single institute.</p><p><strong><em>Patients and methods:</em></strong> A retrospective study of 61 children and adolescent patients (age ≤18years) with well differentiated thyroid carcinoma (DTC) enrolled in the National Institute of Nuclear Medicine and Allied Sciences, Dhaka during the period of  January1986  up to December 2007 was carried out. To allow for a theoretical follow up of at least 5 years the last inclusion year was 2007 and follow up was carried on up to June 2013. All patients were treated by thyroidectomy followed by radioiodine ablation therapy. Whole body scans, Tg, anti Tg Ab and neck ultrasound findings were recorded six months to one year after initial therapy to classify patients into remission, persistent or recurrent disease. Status on last follow up was noted to estimate the survival rate.</p><p><strong><em>Results:</em></strong> A total of 40 patients had papillary carcinoma, 18 had follicular variant of papillary carcinoma (FVPCT) and three had follicular carcinoma. Age range at diagnosis was nine to 18 years with a mean of 15± 2 years. The number of patients ≤10 years were five and &gt; 10 years were 56. There were 12 males and 49 females giving a M: F ratio of about 1:4. Among the 61 patients 30 patients had lymph node metastases and two had both nodal and lung metastases at initial presentation. After one year follow up from the initial radioiodine therapy, 30 patients were in remission and 31 patients had persistent disease. Eventually recurrence occurred in five patients. Three patients died during the whole observation period and all of them were cancer related giving a cancer specific mortality ratio of 0.049%, 95% CI 0 to 0.105%. Cancer specific survival by Kaplan-Meier curve was 98.2%, 98.2% and 66% at 5, 10 and 15 years respectively.</p><p><strong><em>Conclusion:</em></strong> DTC in children and adolescent has a good prognosis in the presence of neck and distant metastases. Awareness of the patient and regular follow up with life long surveillance is essential to obtain a favorable outcome.</p><p>Bangladesh J. Nuclear Med. 20(2): 99-104, July 2017</p>

AbstractThe majority of well differentiated thyroid carcinoma are tumours of low grade malignancy. Laryngotracheal invasion by well differentiated thyroid carcinoma is an uncommon occurrence. The surgical management of patients with thyroid cancer invading the upper airway has primarily been by total laryngectomy. Other surgeons recommend in selected cases partial laryngeal and/or tracheal resection.A total of 122 patients with thyroid carcinoma were treated in our department between 1967 and 1982. Only seven patients with well differentiated tumours had airway invasion. In these seven patients we used a partial laryngeal and/or tracheal resection. In three of the patients with tracheal invasion a myoperichondrial flap was used for closing the tracheal defect. A partial resection of the larynx and trachea, and end to end anastomosis between the trachea and the remaining part of the larynx was performed in another four patients.

Purpose To identify nonmelanoma skin cancer patients with squamous cell carcinoma (SCC) who are at greatest risk of disease-specific mortality. Patients and Methods Prospectively enrolled patients with a minimum of one pathologically confirmed skin SCC lesion, definitive treatment of the SCC lesion(s) resulting in no evidence of disease, and at least 2 months of follow-up after definitive treatment were eligible for the present longitudinal analysis. They received comprehensive clinical, pathologic evaluations and follow-up for patterns of failure and mortality. Results We enrolled 210 patients (187 men and 23 women) with a total of 277 skin SCC lesions and a median enrollment age of 68 years (range, 34 to 95 years). Median follow-up of surviving patients was 22 months. Three-year overall and disease-specific survival (DSS) rates were 70% and 85%, respectively. In univariate analyses, the clinical-pathologic factors associated with adverse DSS were local recurrence at presentation (P = .05), invasion beyond subcutaneous tissues (P = .009), perineural invasion (P = .002), lesion size (P = .0003), and depth of invasion (P = .05). Statistical models identified a homogeneous high-risk group of patients with lesions ≥ 4 cm, perineural invasion, and deep invasion beyond subcutaneous structures. Three-year DSS was 100% for patients with no risk factors versus 70% for patients with at least one risk factor. Conclusion Lesion size ≥ 4 cm and histologic evidence of perineural invasion and deep invasion beyond subcutaneous structures were the clinical-pathologic factors most significantly associated with disease-specific mortality in skin SCC.
