Abstract
Introduction
Thyroid cancer is an important endocrine malignancy worldwide, including papillary carcinoma, which is responsible for more than 90 % of thyroid malignancies. Human epidermal growth factor receptor 2 (Her-2/neu) overexpression plays a significant act in the development, progression, and invasion of various tumors through effects on the cell cycle, angiogenesis, cell movement, and apoptosis.
Objective and methods
The study was conducted as a cross-sectional study, using tissue samples from 53 patients who underwent lobectomy or total thyroidectomy between 2020 and 2022. For histopathological examination and to determine the pathological features of the tumor, tumor specimens were stained for immunohistochemistry using a monoclonal antibody against Her-2/neu.
Results
In this study, Her-2/neu was expressed in 13.2 % of PTC patients and not expressed in normal thyroid tissue. No significant relationship was established between Her-2/neu expression and tumor histological subtype, as well as tumor size, sex, or tumor focality. Furthermore, there was no significant association between Her-2/neu expression and vascular invasion or extrathyroidal extension of the tumor.
Conclusion
No significant Her-2/neu expression was observed in the malignant thyroid tissue. These findings raise questions about the value of Her-2/neu as a potential prognostic factor or target of a specific anticancer treatment for thyroid cancer.
期刊介绍：
Cancer Treatment and Research Communications is an international peer-reviewed publication dedicated to providing comprehensive basic, translational, and clinical oncology research. The journal is devoted to articles on detection, diagnosis, prevention, policy, and treatment of cancer and provides a global forum for the nurturing and development of future generations of oncology scientists. Cancer Treatment and Research Communications publishes comprehensive reviews and original studies describing various aspects of basic through clinical research of all tumor types. The journal also accepts clinical studies in oncology, with an emphasis on prospective early phase clinical trials. Specific areas of interest include basic, translational, and clinical research and mechanistic approaches; cancer biology; molecular carcinogenesis; genetics and genomics; stem cell and developmental biology; immunology; molecular and cellular oncology; systems biology; drug sensitivity and resistance; gene and antisense therapy; pathology, markers, and prognostic indicators; chemoprevention strategies; multimodality therapy; cancer policy; and integration of various approaches. Our mission is to be the premier source of relevant information through promoting excellence in research and facilitating the timely translation of that science to health care and clinical practice.
