Abstract

Background/aims: Gastrointestinal cancers are frequent diseases of particular importance for surgeons with regard to their management and follow-up. Neoplastic diseases activate antioxidant defense systems. As a result, concentrations of redoxal enzymes and their co-factor elements appear to change. The levels of zinc (Zn), copper (Cu) and ceruloplasmin have been found to be critical parameters. In addition, it seems to be important to consider the Cu/Zn ratio in such cases. In this study, changes in the levels of Cu, Zn and ceruloplasmin in patients with gastrointestinal system cancers was evaluated, and the proportion of Cu to Zn (Cu/Zn) is discussed. Methods: In this clinical trial, levels of Cu and Zn were defined with calorimetric methods and ceruloplasmin levels were measured with immunohistochemical methods in a control group of 20 healthy individuals and in 25 patients who underwent surgery for gastrointestinal system cancer. The blood samples were taken preoperatively in gastrointestinal system cancer patients. Results: This study has shown that while the decrease in Zn levels and the increase in ceruloplasmin levels in patients with gastrointestinal system cancers were found to be significant (p<0. 001, p=0. 014) when compared to the control group, the increase in the level of Cu was also found to be significant (p=0. 019). In the patient group, the correlations between serum Cu and serum ceruloplasmin proved to be significant (r=991, p<0. 001). The Cu/Zn ratio, when compared with Zn, ceruloplasmin and Cu, showed significant results (r= 0. 562, r= 0. 500, r=0. 506, p<0. 001). Conclusions: This study shows that serum Cu, Zn and ceruloplasmin levels show changes in gastrointestinal system cancers, but further research is needed to demonstrate the importance and significance of these parameters and their relation with other contributing neoplastic factors.

Özet

Amaç: Gastrointestinal sistem kanserleri hem tedavi hem de takip açısından cerrahlar için önemli ve sık karşılaşılan bir hastalık grubudur. Neoplastik hastalıklar antioksidan defans mekanizmalarını aktive ederler, bunun sonucunda redoksan enzimler ve kofaktör elementler değişikliğe uğrarlar. Serum bakır, çinko ve seruloplazmin düzeyleri bu hastalarda değerli parametreler olabilir. Çalışmamızda gastrointestinal sistem kanserli hastalarda serum bakır, çinko, seruloplazmin değişikleri değerlendirilmiş ve Cu/Zn oranının önemi tartışılmıştır. Yöntem: Bu randomize klinik çalışmada serum Cu/Zn oranı kalorimetrik yöntemlerle, seruloplazmin düzeyleri ise imminokimyasal yöntemle değerlendirildi. Çalışma grubu 20 sağlıklı birey ve cerrahi planlanan 25 gastrointestinal sistem kanserli hastadan oluştu. Kan örnekleri preoperatif dönemde alındı. Bulgular: Çalışmamızda gastrointestinal sistem kanserli hastalarda kontrol grubuna göre serum Zn düzeylerinde azalma olurken, seruloplazmin düzeylerinde artış belirgin olarak görülmüştür. (p<0, 01, p=0, 019). İki grup karşılaştırıldığında serum bakır düzeylerindeki artışta, kanserli hasta grubunda istatistiksel olarak anlamlı idi (p=0, 019). Hastalıklı grupta; serum bakır ve seruloplazmin yükseklikleri belirgin olarak korelasyon gösterdi. (r=0, 991, p<0, 001). Hastalıklı grupta serum parametreleri Cu/Zn oranı ile karşılaştırıldığında daha anlamlı sonuçlar elde edildi. (r= 0, 562, r= 0, 500, r= 0, 506, p<0, 001). Sonuç: Çalışmamızda, gastrointestinal kanserli hastalarda serum bakır, çinko ve serüloplazmin düzeylerinde değişikliklerin olduğu görülmüştür. Ancak bu parametrelerdeki değişikliklerin, diğer neoplastik faktörlerle ilişkilerini gösterebilmek için daha kapsamlı çalışmalara ihtiyaç vardır.
