Abstract

We analysed glutathione S-transferase M1, T1, and P1 gene polymorphisms in a case control study to asses their susceptibility to prostate cancer in Turkish population. Polymorphisms were determined by PCR-based methods in 115 control subjects and 115 prostate cancer patients. The frequencies of polymorphisms were compared between patients and controls by logistic regression analysis. Possible associations of genetic profiles with respect to the Gleason score and patient age were also investigated. Besides GSTT1 null genotype has slightly increased prostate cancer risk (odds ratio(OR) = 1.50, 95% confidence interval (CI), 0.85-2.66), its association with prostate cancer risk was statistically significant among smokers (OR = 3.20, 95%CI, 1.06-9.70). GSTP1 Val/Val genotype was more common in cancer patients (OR = 1.63, 95%CI, 0.61-4.37). However, the combination of GSTP1 Ile/Ile and GSTT1 null genotype was associated with a higher risk (OR = 2.67, 95%CI, 1.00-7.10). Our results suggest that GSTT1 null genotype may modify prostate cancer risk among cigarette smokers seperately, and in combination with GSTP1 Ile/Ile genotype, irrespective of the smoking habit in Turkish population.

Özet

Türk toplumunda prostat kanseri riski üzerindeki etkilerini değerlendirmek amacı ile glutatyon S-transferaz M1, T1 ve P1 gen polimorfizmlerini bir vaka kontrol çalışması ile araştırdık. Polimorfizmler 115 kontrol ve 115 prostat kanseri hastasında polimeraz zincir reaksiyonuna dayalı yöntemler ile saptandı. Kontrol ve prostat kanseri gruplarında polimorfizmlerin sıklıkları lojistik regresyon analizi ile kar- şılaştırıldı. Ayrıca genetik profiller ile Gleason skoru ve hasta yaşları arasında bir ilişki varlığı araştırıldı. GSTT1 null genotipin prostat kanseri riskini hafif derecede artırdığı görülmekle birlikte (odds oranı (OR) = 1.50, %95 güven aralığı (CI), 0.85-2.66), sigara içenlerde prostat kanseri ile ilişkisinin istatistiksel olarak anlamlı olduğu saptandı (OR = 3.20, %95CI, 1.06-9.70). GSTP1 Val/Val genotipi vakalarda daha sıktı (OR = 1.63, 95%CI, 0.61-4.37). Ancak, GSTP1 Ile/Ile ve GSTT1 null genotip kombinasyonunda risk anlamlı derecede daha yüksek olarak bulundu (OR = 2.67, %95CI, 1.00-7.10). Bu sonuçlar, Türk toplumunda GSTT1 null genotipin sigara içen bireylerde prostat kanseri riskini artırdığını göstermiştir. Ayrıca GSTT1 null ve GSTP1 Ile/Ile genotip birlikteliğinin sigara kullanımından bağımsız olarak prostat kanseri riskini arttırdığını göstermiştir.
