BACKGROUND
During follow-up for patients with medullary thyroid cancer (MTC), the levels of serum calcitonin and carcinoembryonic antigen are important, and the doubling time of these biomarkers significantly correlates with disease progression. Other antigens are present in tumor tissue and the
An immunohistochemical study using a panel of monoclonal antibodies (mAbs) against blood group A, B, H and Lewis antigens Le(a), Le(b), Le(x) and Le(y) and lectins, such as PNA, VVA-B4 and UEA -1, was carried out to investigate the aberrant expression of carbohydrate antigens in formalin-fixed,
Conflicting data concerning the association between obesity and differentiated thyroid cancer (DTC) may be attributed to the lack of records showing dietary intake and inadequate evaluation of nutrient composition. We evaluated 115 DTC patients carefully paired with 103 healthy control individuals
BACKGROUND
Medullary thyroid cancer (MTC) is capable of secreting several proteins, such as calcitonin (Ct), carcinoembryonic antigen (CEA), chromogranin and others. Recently, we observed an aggressive MTC with high levels of serum carbohydrate antigen 19.9 (Ca 19.9) and a rapid evolution to
The reactivity of monoclonal antibody FB21, which recognizes a sialic acid-dependent carbohydrate epitope, was tested with 94 non-neoplastic and neoplastic thyroid tissue specimens using immunohistochemical methods on formalin-fixed, paraffin-embedded tissue sections. These specimens included 11
OBJECTIVE
Presently, no clinical tools are available to diagnose the metastatic potential of medullary thyroid cancer (MTC) at disease presentation. Surveillance with calcitonin (Ct) and carcinoembryonic antigen (CEA) is currently recommended for the observation and diagnosis of metastatic disease
A 77-year-old man was admitted to the hospital with a thyroid nodule. The levels of serum tumor-associated carbohydrate antigens (CA 50, CA 19-9) and thyroglobulin (HTG) were markedly increased. We performed total thyroidectomy and right neck lymph node dissection. After treatment, the serum CA 50,
OBJECTIVE
In 2016, there were an estimated 56 870 new cases of thyroid cancer (TC) in the USA. Fine needle aspiration cytology (FNAC) is the most safe, accurate and cost-effective method for the initial investigation of thyroid nodules. FNAC is limited by the inability to diagnose malignancy in
Thyrogen (thyrotropin alfa for injection), recombinant human TSH (rhTSH), has been successfully used to enhance diagnostic radioiodine scanning and thyroglobulin testing in the follow-up of patients with thyroid cancer and as an adjunctive treatment for radioiodine thyroid remnant ablation. However,
The aim of the study is to explore the possibility of detecting metastatic lymph nodes by FTIR spectra during the surgery of thyroid cancer. The FTIR spectra of 20 metastatic lymph nodes and 69 non-metastatic ones were collected via an ATR (attenuated total reflectance) probe. For each spectrum, 28
Forty primary carcinomas of the thyroid of different histological types were reviewed and studied histochemically, with the aim of identifying and assessing "mucin secretion". The patterns of extracellular "pure alcianophilia" and "mixed alcianophilia" were noted in 7.5% and about 50% of these
Affinity chromatography on a concanavalin A (con A)-Sepharose column is a potentially useful for the isolation of whole thyroglobulin (Tg) at least from normal thyroid tissue. In addition to being a simple procedure for the isolation of Tg, large amounts of Tg can be applied to the column and
The chemical and immunological properties of thyroglobulin (Tg) in tissue obtained from a patient co-existed with two types of thyroid tumors, i.e., functioning and non-functioning, and were compared with the properties of Tg that was isolated from adjacent peripheral tissue. In the present
The incidence of papillary thyroid cancer has increased these last decades due to a better detection. High prevalence of nodules combined with the low incidence of thyroid cancers constitutes an important diagnostic challenge. We propose to develop an alternative diagnostic method to reduce the
