Anaplastic thyroid cancer is an uncommon malignancy with a poor prognosis. Elderly patients are most commonly afflicted and survival past 3 years occurs in less than 5% of patients. Management of these patients is challenging, and the importance of palliation, airway protection, and aggressive resection is debated. In this report, we describe a patient with anaplastic thyroid carcinoma who pres...

OBJECTIVES To ascertain if there has been a change in the pattern of thyroid cancer in Sri Lanka. If so, whether there is a correlation to the implementation of the programme of iodination. DESIGN Retrospective (1974-1986) and prospective (1987-2001). SETTING Kandy Hospital (1974-1982), Peradeniya Hospital (1982-2001) and private hospitals in Kandy (1979-2001). METHOD Three hundred consec...

Anaplastic thyroid carcinomas (ATC) are very aggressive cancers. The median survival is 4 to 5 months and the long survival is rare. Fifteen to 50 percent of the patients with anaplastic carcinoma have extensive local invasion and distant metastases at initial presentation of the disease (1). In 90% of the cases, lungs and pleura are sites of distant metastasis. Other metastatic sites are bone,...

Thyroid carcinoma is the most common malignant endocrine neoplasia. Differentiated thyroid carcinomas (DTCs) represent more than 90% of all thyroid carcinomas and comprise the papillary and follicular thyroid carcinoma subtypes. Anaplastic thyroid carcinomas correspond to less than 1% of all thyroid tumors and can arise de novo or by dedifferentiation of a differentiated tumor. The etiology of ...

Undifferentiated thyroid carcinoma is one of the most aggressive human cancers with frequent RAS mutations. How mutations of the RAS gene contribute to undifferentiated thyroid cancer remains largely unknown. Mice harboring a potent dominant negative mutant thyroid hormone receptor β, TRβPV (Thrb(PV/PV)), spontaneously develop well-differentiated follicular thyroid cancer similar to human cance...

Anaplastic thyroid carcinoma (ATC) is a poorly differentiated thyroid cancer. It cannot uptake iodine or synthesis thyroglobulin. The incidence is low; about 2% 5% of thyroid cancer. The peak age incidence is 60 70 years and it is more common in females (55% 77% of all patients). In recent years, the incidence has declined; however, it may be higher in areas of endemic goiter. ATC may occur wit...

Even though management of thyroid cancer is generally standardized and has an overall excellent long-term outcome, anaplastic thyroid cancer (ATC) continues to be a major diagnostic and therapeutic challenge. ATC is an uncommon thyroid malignancy with a poor prognosis. American Thyroid Association guidelines acknowledge the complexity of airway management in these patients. We studied the liter...

Thyroid squamous cell carcinoma is very rare. At present, it limited to case reports. Since the thyroid follicular epithelium non-squamous epithelium, how primary (SCC) of occurs still a controversial issue. Hashimoto’s thyroiditis (HT) considered be an independent risk factor for cancer, under basis HT, tumor cells evolve and develop papillary (PTC), particularly de-differentiate into SCC elus...

PURPOSE Anaplastic thyroid cancer is known to have a poor prognosis due to its aggressive and rapid metastasis with median survival of less than 6 months. Multimodal treatment involving surgery and chemoradiotherapy has been used to improve the survival of patients. Here, we retrospectively review of treatment outcome of 13 consecutive patients who were treated at a single center. MATERIALS A...

Fine-needle aspiration (FNA) is the most commonly used pre-operative technique for diagnosis of malignant thyroid tumor. However, many benign lesions, with indeterminate diagnosis following FNA, are referred to surgery. Based on multifunctionality of the endogenous galectin-1, we aimed to assess its status for early diagnosis of thyroid cancer. Immunohistochemistry for galectin-1 and -3 was per...
