\n\nMethods: We conducted a large-scale, case-control study involving 3938 patients with newly diagnosed lung cancer and 1700 healthy controls. Genotyping was performed
with peripheral blood DNA for MTHFR C677T polymorphisms. Statistical significance was estimated by logistic regression analysis.\n\nResults: The MTHFR C677T frequencies of CC, CT, and TT genotypes were 34.5%, 48.5%, and 17% among lung cancer patients, and 31.8%, 50.7%, and 17.5% in the controls, respectively. The SC79 MTHFR 677CT and TT genotype showed a weak protection against lung cancer compared with the homozygous CC genotype, although the results did not reach statistical significance. The age-and gender-adjusted odds ratio (OR) of overall lung cancer was 0.90 (95% confidence
interval (CI), 0.77-1.04) for MTHFR 677 CT and 0.88 (95% CI, 0.71-1.07) for MTHFR 677TT. However, after stratification analysis by histological type, the MTHFR 677CT genotype showed a significantly decreased risk for squamous cell carcinoma (age-and gender-adjusted OR, 0.78; see more 95% CI, 0.64-0.96). The combination of 677 TT homozygous with 677 CT heterozygous also appeared to have a protection effect on the risk of squamous cell carcinoma. We observed no significant interaction between the MTHFR C677T polymorphism and age and gender or smoking habit.\n\nConclusions: This is the first reported study focusing on the association between MTHFR C677T polymorphisms and the risk of lung cancer in a Korean population. The T allele was found to provide a weak protective association with lung squamous cell
“Pyrimidine analogues such as 5-fluorouracil (5-FU) are widely used in adjuvant and palliative treatment of various solid tumours. However, their administration may be associated with severe adverse events such as myelosuppression, mucositis find more or cardiotoxicity. Cardiotoxicity is a relatively rare event but its fatal outcomes occur at a rate of 2.2-13.3%. Since 5-fluorouracil is widely used in medical oncology, cardiotoxicity associated with its administration may significantly impair treatment of patients with cancers sensitive to pyrimidine analogues. This article reviews fluoropyrimidine-associated cardiotoxicity and presents a case report of a young woman who experienced this complication during 5-fluorouracil treatment.”
“Chronic inflammation is a hallmark of HIV infection. Eicosanoids reflect inflammation, oxidant stress, and vascular health and vary by sex and metabolic parameters. Raltegravir (RAL) is an HIV-1 integrase inhibitor that may have limited metabolic effects. We assessed urinary F-2-isoprostanes (F-2 -IsoPs), prostaglandin E-2 (PGE-M), prostacyclin (PGI-M), and thromboxane B-2 (TxB(2)) in HIV-infected women switching to RAL-containing antiretroviral therapy (ART).
