Background: Endometriosis is a chronic hormone-dependent inflammatory disease determined by the presence of foci endometrial tissue outside uterine cavity. Genetic factors occupy leading position in etiopathogenesis this disease. With endometriosis, there pronounced hormonal imbalance sex hormones both lesion and body sick woman as whole. The aim study:To study associations polymorphism hormone...

Results On univariate analysis, hypertension was strongly associated with a decreased risk of late urinary toxicities (OR= 0,048, 95% CI 0,004 0,620; p= 0,022). Patients receiving hormone therapy had a significantly higher incidence of acute skin toxicity (OR= 27,667 95%CI:1,203-636,11; p = 0,029). The exchange C>T in the position 11322 (intron 3) of the TP53 gene (rs35117667) was significantly...

Soft tissue sarcomas (STS) are tumors of mesodermal origin, comprising about 1% of all adult neoplasms. Management of such tumors is an important medical challenge. TP53 codon 72 polymorphism results in either the arginine or proline form of the p53 protein; several studies have investigated whether codon 72 polymorphisms are risk and prognostic factors for cancer. We investigated p53 codon 72 ...

Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome frequently associated with germ line TP53 mutations. Unpredictable and disparate age of cancer onset is a major challenge in the management of LFS. Genetic modifiers, including the MDM2-SNP309 polymorphism, and genetic anticipation have been suggested as plausible explanations for young age of tumor onset, but the molecular mechanis...

objective: to review her-2/neu and tp53 status and their correlation with all other prognostic clinicopathologic features of infiltrative ductal breast carcinomas. materials and methods: this cross sectional study was performed on 139 patients with infiltrative ductal breast carcinoma who were diagnosed between may 2000 and march 2006 at the surgery and pathology departments of alzahra hospital...

The p53 tumor suppressor pathway is central both in reducing cancer frequency in vertebrates and in mediating the response of commonly used cancer therapies. This article aims to summarize and discuss a large body of evidence suggesting that the p53 pathway harbors functional inherited single-nucleotide polymorphisms (SNPs) that affect p53 signaling in cells, resulting in differences in cancer ...

Advances in understanding the molecular basis of primitive neuroectodermal tumors of the central nervous system (CNS-PNET) biology are critical to improve patient outcome. Recently, new data on their molecular features have been reported, suggesting that supratentorial PNET (s-PNET) in adult patients may represent a specific tumor entity among CNS-PNETs. In this study, we analyzed the clinicopa...

Recent studies indicated that the Arg allele is preferentially mutated and retained in various human cancers arising in Pro/Arg heterozygotes and it may be an important biomarker in colon cancer prognosis. In this study, DNA was isolated from paraffine-embedded colon tumor tissue samples of 35 cases diagnosed as colon carcinoma. We have observed PCR-RFLP genotyping for the codon 72 exon 4 polym...

DNA repair enzymes function in major pathways to reverse DNA damage, including base excision repair (BER). Missense polymorphisms in BER repair genes may contribute to differences in DNA repair capacity, specific mutations, and susceptibility to cancer in the presence of exposure to carcinogens such as cigarette smoking. In a study of 1,604 incident colon cancer cases and 1,969 matched populati...
