Abstract

Objectives: CYP2D6 is highly polymorphic and a common variant CYP2D6*4 results in the generation of poor metabolizer enzyme. The CYP2D6*4 variant has been associated with altered susceptibility to several cancers. The aim of the present case-control study aims to investigate the association between CYP2D6*4 polymorphism and the risk of papillary thyroid carcinoma (PTC). Materials and methods: Astudy population of 97 caseswith PTC and 120 controls were included in the study. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method to detect the presence of CYP2D6*4. Results: The CYP2D6*4 was associated with significantly increased PTC risk when compared with controls (odds ratio [OR]=1.995, 95% confidence interval [CI]=1.060–3.752, p=0.031). Besides, CYP2D6*4 allele frequency was higher in PTC patients with age ≤50 years when compared to those with age >50 (OR=2.380, 95% CI=1.191–4.755, p=0.013). CYP2D6*4 allele frequency was higher in patients who had encapsulated tumors, but it was not statistically significant (p=0.111). No relationship was found between CYP2D6*4 and PTC variants or between early (I/II) and late (III/IV) tumor stages. Conclusions: Our findings indicate that the poor metabolizer CYP2D6*4 genotype may be a risk factor, especially in early PTC development. Further research with larger groups is required for the confirmation of our consequences.

Özet

Amaç: CYP2D6 oldukça polimorfiktir ve yaygın bir varyant olan CYP2D6*4, zayıf metabolizör enziminin üretilmesine neden olur. CYP2D6*4 varyantı birçok kansere yatkınlıkla ilişkilendirilmiştir. Bu vaka kontrol çalışmasında CYP2D6*4 polimorfizmi ile papiller tiroid karsinomu (PTK) arasındaki ilişkinin araştırılması amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya 97 PTK ve 120 kontrol olgusu dahil edildi. CYP2D6*4’ün varlığını saptamak için PCR-RFLP yöntemiyle genotiplendirme yapıldı. Bulgular: CYP2D6*4’ün kontrollerle karşılaştırıldığında anlamlı düzeyde artmış PTK riski ile ilişkili olduğu bulundu (OR=1.995, %95 CI=1.060–3.752, p=0.031). Ayrıca, CYP2D6*4 alel sıklığı yaşı ≤50 olan PTK hastalarında yaşı >50 olanlara göre daha yüksekti (OR=2.380,%95 CI=1.191–4.755, p=0.013). Kapsüllü tümörleri olan hastalarda CYP2D6*4 alel sıklığı daha yüksekti, ancak istatistiksel olarak anlamlı değildi (p=0.111). CYP2D6*4 ve PTK varyantları arasında veya erken (I/II) ve geç (III/IV) tümör evreleri arasında ilişki bulunmadı. Sonuç: Bulgularımız, zayıf metabolizör CYP2D6*4 genotipinin, özellikle erken yaş PTK gelişimi için bir risk faktörü olabileceğine işaret etmektedir. Sonuçlarımızın doğrulanması için daha büyük gruplarla araştırma yapılması gerekmektedir.
