Cím:	Colorectal cancer risk in relation to genetic polymorphism of cytochrome P450 1A1, 2E1, and glutathione-S-transferase M1 enzymes / István Kiss, János Sándor, Gábor Pajkos, Barna Bogner, Géza Hegedűs, István Ember
Dátum:	2000
Megjegyzések:	Chemical carcinogens generally require metabolic activation in order to be able to bind to DNA and contribute to cancer causation. Most of the human metabolizing enzymes are genetically polymorphic, and these polymorphisms may affect the enzyme activity or inducibility. In our present study we investigated the connection between genetic polymorphism of cytochrome P450 1A1, 2E1 (phase I enzymes) and glutathione-S-transferase M1 (a phase II enzyme) and colorectal cancer occurrence in a Hungarian population. The CYP 2E1 c2 allele proved to be in significant association with colorectal cancer (OR: 1.91, 95% CI: 1.05-3.52), the CYP 1A1 Val allele was also overrepresented among colon cancer patients (OR: 1.57, 95% CI: 0.90-2.74), and the frequency of GSTM1 homozygous 0 genotype showed only minor difference (OR: 1.19, 95% CI: 0.75-1.35). Combined analysis of the polymorphisms showed that individuals carrying all the three "high-risk" alleles have a strikingly increased risk for sporadic colorectal cancer (OR: 4.62, 95% CI: 1.23-25.68).

Cím:	Prognostic factors in Hungarian breast cancer patients / Edit Nádasi, Béla Anga, János Sándor, Judit Megyesi, Dezső Kelemen, Marcella Mottolese, Pier Giorgio Natali, Géza Hegedűs, István Arany, István Ember
Dátum:	2007
Megjegyzések:	Breast cancer is the most common cancer among women, with variable outcomes, justifying a continuous search for new parameters to predict accurate prognosis and indicate suitable adjuvant therapy for patients. MATERIALS AND METHODS: Fourty-four stage I-III breast cancer specimens were investigated immunohistochemically for the expression of cyclooxygenase-2 enzyme (COX-2), hormone receptors, tumor suppressor gene p53, oncogene HER2 and proliferation marker Ki-67. Additionally, twelve specimens were also investigated for the presence of the phosphorylated extracellular signal-regulated kinase (pERK). RESULTS: It was demonstrated that expressions of biological markers were related to each other (ER to p53 and Ki-67, COX-2 to ER, PgR, Ki-67 and p53, Ki-67 to p53 and PgR, p53 to PgR). CONCLUSION: Our data indicate that concomitant immunohistochemical evaluation of cyclooxygenase-2, hormone receptors, p53 and Ki-67 may be of clinical value in determining an accurate prognosis.
