PREDICTIVE VALUE OF SOMATIC MUTATIONS FOR THE DEVELOPMENT OF MALIGNANCY IN THYROID NODULES BY CYTOPATHOLOGY.

Objective: The purpose of our prospective longitudinal study was to evaluate the predictive efficacy of genetic testing for malignancies in fine-needle aspiration biopsy samples that are cytologically benign at the time of biopsy.

Methods: A total of 779 aspirated cytological samples collected from thyroid nodules of 626 patients were included in a 3-year follow-up study. Consecutive patients with cytologically benign thyroid nodules by the Bethesda System for Reporting Thyroid Cytopathology were enrolled in the study.

Genetic Alterations in Hungarian Patients with Papillary Thyroid Cancer.

The incidence of thyroid cancers is increasing worldwide. Some somatic oncogene mutations (BRAF, NRAS, HRAS, KRAS) as well as gene translocations (RET/PTC, PAX8/PPAR-gamma) have been associated with the development of thyroid cancer. In our study, we analyzed these genetic alterations in 394 thyroid tissue samples (197 papillary carcinomas and 197 healthy).

[Diabetes in patients with malignant tumors].

Disturbances of the carbohydrate metabolism are fairly common is patients with malignancy. On the other hand, diabetes appears to have an effect on the development and progression of various tumors. Malignant diseases and the therapies used in their treatment often have an impact on carbohydrate metabolism, while diabetes may hinder specific oncotherapy or influence oncological therapeutic decisions.

Novel genetic mutation in the background of Carney complex.

Carney complex is a rare disease inherited in an autosomal dominant manner. It is mostly caused by inactivating mutations of the subunit of protein kinase A. Carney complex is associated with atrial myxoma, nevi or myxomas of the skin, breast tumor and endocrine overactivity.

[Comparative study of somatic oncogene mutations in normal thyroid tissues and thyroid neoplasms].

It is established that numerous somatic oncogene mutation (BRAF, NRAS, HRAS, KRAS) and gene translocations (RET/PTC, PAX8/PPAR-gamma) are associated with the development of thyroid cancer. In this study 22 intraoperative thyroid tissue samples (11 pathologic and 11 normal) were examined. Somatic single nucleotide polymorphisms were analyzed by LigthCycler melting method, while translocations were identified by real-time polymerase chain reaction technique.

[Verner-Morrison syndrome: a case study].

Verner and Morrison described a syndrome of watery diarrhea, hypokalemia, and achlorhydria (WDHA) in 1958. VIPomas producing high amounts of vasoactive intestinal peptide (VIP) commonly originate from the pancreas. Typical symptoms play a momentous role in the diagnosis of VIPoma.
