[Chromosome aberrations in patients with papillary thyroid cancer and other neoplasms].
Cancer is essentially a genetic disease resulting from congenital or acquired alterations in some cells of the patient. Such changes may occur in particular oncogens and are responsible for the tumour phenotype of the affected population of cells. In contrast, unaltered tumour-suppressor genes are responsible for suppressing the neoplastic phenotype, and their inactivation by deletion or mutation permits cancerous development in the affected cells. The genetic model of carcinogenesis is based on the idea mutations at the DNA level, what creates a functional imbalance between the oncogenes and the tumour-suppressor genes, resulting in uncontrolled clonal proliferation. The ret/PTC oncogene is unique to papillary thyroid cancer. The paper presents a correlation analysis between chromosomal changes in papillary thyroid cancer and abnormalities of chromosomes in patients with breast cancer and chronic lymphocytic leukemia.
