Öğe Anticancer Activity of Calcium Channel Blockers in Colon Cancer Cell Culture(Sivas Cumhuriyet University, 2022) Alandağ, Celal; Öztürk, AyşegülObjective: Repurposing non-cancer drugs for cancer treatment has many advantages. We can access to a new cancer drug easily, quickly and cheaply. In addition, we generally know safety prifile of repurped drugs. There are few studies in the literature investige the anticancer effects of Calcium channel blockers (CCBs). We planned to investigate the anticancer effects of CCBs on colon cancer cell line.Material and Method: We adminestered different doses of T-type CCB NNC-55-0396 and L-type CCB amlodipine on colon cancer cell line HT-29. MTT analysis was performed at 48 hours to measure cell viability. The dose-response curve was constructed using GraphPad Prism.8 programme.Results: Amlodipine caused more than 90% cytotoxicity at all concentrations of 500, 250, 100, 50, 10 µg/ml in MTT analysis at 48 hours. Similarly, NNC-55-0396 caused more than 90% cytotoxicity at all 80, 40, 20, 10.5 µM concentrations.Discussion: In our study, NNC-55-0396 and amlodipine molecules showed severe cytotoxicity on HT-29 cells. There are publications indicating that it may have other anticancer effects other than cytotoxicity. They are promising molecules as anti-cancer drugs. They should be investigated in clinical studies alone or in combination with other cancer drugs.Öğe Özel Tip Meme Karsinomları: Klinik, Histolojik Özellikleri ve Sağkalım Sonuçları(Sivas Cumhuriyet Üniversitesi, 2024) Erdiş, Eda; Yılmaz, Mukaddes; Uçar, Mahmut; Demir, Necla; Alandağ, Celal; Yücel, BirsenAmaç: Bu çalışmada kliniğimize başvuran özel tip meme kanseri tanılı hastaların klinik özelliklerini ve sağkalım sonuçlarını araştırdık. Materyal-Metod: Cumhuriyet Üniversitesi Onkoloji Merkezi’ne 2010-2020 yılları arasında başvuran meme kanserli tüm nadir, histolojik olarak özel alt tip hastalarının demografik, klinikopatolojik ve sağkalım özellikleri retrospektif olarak incelenmiştir. Bulgular: Çalışmada 1198 invaziv meme kanserli hastaların dosyaları incelenmiş ve bunlardan 104’ünün (8%) diğer histolojik özel alt tipinde olduğu tespit edilmiştir. Apokrin kanser 19 (8%), musinöz tip 19 (8%), invaziv kribriform 17 (%7), invaziv papiller 15 (%6), metaplastik tip 11 (%4), invaziv mikropapiller 9 (%4), nöroendokrin 6 (%2), tubuler tip 3 (%1), mikroinvaziv 3 (%1), undifferansiye 2 (%1) hastada saptanmıştır. Bu hastaların büyük bir kısmı 102 (98%)’ si kadın olup median yaşı 52 (26-82) bulunmuştur. Kadınların 60 (%59)’u postmenopozal, 42 (41%)’isi de premenopozaldir. 79 (76%) hastanın ECOG Performans skoru (PS) 0, 17 (16%)’sinin ECOG PS 1, 8 (8%)’inin ECOG PS 2 olarak izlenmiştir. Hastalar sorgulandığında 50’sinde (48%) komorbid hastalıklar olduğu, 26’sinde (25%) ailede meme kanseri öyküsü olduğu görülmüştür. Tanıda 25 (24%) hastanın evre I, 50 (48%) hastanın evre II ve 26 (25%) hastanın evre III, 3 (%3) hastanın evre IV olduğu tespit edilmiştir. Histopatolojik değerlendirmelere göre hastaların 75’inde (72%) estrogen reseptörü (ER) pozitif, 69’ünde (66%) progesterone reseptörü (PR) pozitif, 26’sında (25%) HER2-pozitif olarak bulunmuştur. İntraduktal component 54 (60%) hastada tespit edilmiştir. Multisentrisite 15 (16%) hastada izlenmiştir. 56 (54%) hastaya modifiye radikal mastektomi, 45 (43%) hastaya meme koruyucu cerrahi uygulanmıştır. 76 (73%) hastaya adjuvant kemoterapi, 73 (70%) hastaya hormonterapi ve 72 (68%) hastaya radyoterapi verilmiştir. Medyan takip 54 (1-201) ay olup takipte 13 (13%) hastada metastaz, 7 (7%) hastada nüks tespit edilmiş. Hastaların 5 ve 10 yıllık overall survival sırasıyla 86% ve 77% olup, 5 ve 10 yıllık event-free survival sırasıyla %79 ve %70 olarak bulunmuştur. Sonuç: Çalışmamızda özel tip meme karsinomlu hastaların tamamına yakını nonmetastatik olup histopatolojik olarak hormon reseptörü pozitif ve düşük gradelidir. Özel tipler arasında, 5 ve 10 yıllık overall survival/ event-free survival istatistiki olarak anlamlı bulunmamıştır.Öğe Prognostic Significance of HALP Score in Early Stage Triple-Negative Breast Cancer(2022) Alandağ, Celal; Yılmaz, Mukaddes; Uçar, Mahmut; Demır, Necla; Erdiş, Eda; Yücel, BirsenObjectives: Triple-negative breast cancer (TNBC) is an aggressive and poor prognostic subtype of breast cancer. This study aims to evaluate the prognostic value of clinicopathological factors and novel inflammatory marker HALP (hemoglobin, albümin, lymphocyte, platelet) score in early-stage TNBC patients. Methods: It was one center, retrospective study. We analyzed some parameters of TNBC patients and the effects of these parameters on overall survival (OS) and disease-free survival (DFS). The cut-off value of the HALP score was accepted as 32,4, which was calculated with the X-tile program. Chi-square test was used to compare 5 and 10 years survival rates, Kaplan-Meier and Cox regressions tests were used to estimate median survivals. Results: There were 166 patients, the median age was 50, median follow-up time was 64 (range, 2-262) months, median OS was not reached, median DFS was 185 months. In multivariate analysis, HALP score was found not a prognostic factor, stage, tumor necrosis, lymph node extracapsular extension was found a negative prognostic factor for both OS and DFS. Conclusion: Although, in other studies, HALP score was reported prognostic factor in some cancer types, in our study not found a prognostic factor in early-stage TNBC. But future studies should be done about HALP score in metastatic breast cancer.Öğe Relationship Between Interleukin-28B Gene Polymorphism and Chronic Hepatitis B Infection(Tıbbi Kayıtlar Derneği, 2022) Alandağ, Celal; Demirel, Ulvi; Kargün, KürşatAim: Interleukin 28B (IL28B) gene polymorphism may play a role in hepatitis B virus (HBV) infection prognosis. We investigated the effects of IL28B gene polymorphism on viral clearance and viral load in chronic hepatitis B (CHB) patients.Material and Methods: We included 146 individuals who applied to our center between October 2011 and October 2012. CHB (N=117) and control (N=29) groups were compared in terms of IL28B gene rs12979860, rs12980275 gene region polymorphisms, and IL28B gene expression (mRNA) levels.Results: There was no statistically significant difference between groups in terms of rs12979860 gene region polymorphism rates (χ2=0.36, p=0.835). But there was a significant association between groups in terms of rs12980275. In the CHB group, the A/A genotype was much more, (χ2=55.2, p<0.001), G/A and G/G genotypes were less frequent. There was no statistically significant difference between the groups in terms of IL28B expression levels.Conclusion: This study revealed the genotype profile of the IL28B gene of our region. It is the first study on this subject in our region. The association between CHB and rs12980275 polymorphism may be important. Our results will contribute to future studies.
