Abstract Purpose Prevalence of papillary thyroid cancer (PTC) is increased in patients with acromegaly. We aimed to determine the protein expression of BRAF, RAS, RET, insulin like growth factor 1(IGF1), Galectine 3, CD56 in patients with PTC related acromegaly and to compare the extensity of these expressions with normal PTC patients and benign thyroid nodules. Methods We studied 313 patients with acromegaly followed in Cerrahpasa Medical Faculty, Endocrinology and Metabolism Clinic between 1998 and 2015. On the basis of availability of pathological specimen of thyroid tissues, thyroid samples of 13 patients from 19 with acromegaly related PTC (APTC), 20 normal PTC and 20 patients with multinodulary goiter (MNG) were histopathologically evaluated. Protein expressions were determined via immunohistochemical staining in ex-vivo tumor samples and benign nodules. Results The incidence of PTC in acromegaly patients were 6% (n=19). Among patients with PTC, APTC and MNG, all the immunohistochemical protein expressions we have studied were higher in papillary thyroid cancer groups (p<0.01, for all). Between PTC group without acromegaly and APTC, galectin 3 and IGF1 expression was significantly higher in acromegalic patients (p<0.01 for all) while RAS was predominantly higher in PTC patients without acromegaly (p<0.01). Conclusion BRAF expression was not higher in PTC with acromegaly patients compared to PTC patients without acromegaly. Galectine 3 and IGF1 were expressed more intensively in APTC. These positive protein expressions may have more influence on determining malign nodules among acromegaly patients.

The Relationship

Background: Thyroid cancer is more common in women at reproductive age, suggesting the relationship between its high-incidence and therapeutic use of hormonal medications, such as oral contraceptives (OCPs). The aim of this study was to identify the effect of low-dose combined OCP (LD-COC) on proliferation, apoptosis, and migration of human papillary thyroid cancer (PTC) BCPAP cell line. Materials and Methods: BCPAP cells were cultured and treated with the combination of 90nM levonorgestrel (LNG) and 20nM ethinylestradiol (EE) for 48 hours. Afterward, using 3-(4, 5-dimethylthiazol-2-yl) -2, 5-diphenyltetrazolium bromide (MTT) assay, the proliferation of the cells was measured. Apoptosis was determined by using a Caspase-3 ELISA kit. Migratory properties of combined LNG and EE were studied through wound scratch assay. The expression levels of pro-apoptotic factor BAX, anti-apoptotic factor Bcl2, and proliferation marker Ki67 were analyzed by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and western blotting. Results: Upon treatment with the combination of LNG and EE, proliferation and migration of BCPAP cells were significantly enhanced. However, LNG and EE remarkably inhibited apoptosis of these cells. Furthermore, treating PTC cells with combined LNG and EE caused a marked increase in the expression of Bcl2 and Ki67 and a considerable decrease in BAX levels (P˂ 0.05). Conclusion: Our data linked the use of COCs and the progression and aggressiveness of PTC, suggesting the role of these hormonal compounds as promoting factors for PTC tumors. Despite these observations, further investigations will be required to fully establish the pathogenic impact of these medications on PTC. [GMJ.2020;9:e1648]
