Association between serum arsenic and oral cancer risk: A case-control study in southeast China.

Objectives: Evidence on serum arsenic and oral cancer risk was limited. We aimed to evaluate the association between serum arsenic and the risk of oral cancer in a southeast China population.

Methods: Serum arsenic was determined for 325 oral cancer patients and 648 controls using inductively coupled plasma-mass spectrometry (ICP-MS).

Erythrocyte ω-3 polyunsaturated fatty acids are inversely associated with the risk of oral cancer: a case-control study.

Objectives: Evidence about ω-3 polyunsaturated fatty acids (ω-3 PUFAs) and oral cancer risk were limited. We aimed to evaluate the association of erythrocyte ω-3 PUFAs with the risk of oral cancer in a population from China.

Methods: Erythrocyte ω-3 PUFAs of 236 oral cancer patients and 300 controls were determined by gas chromatography.

Dietary patterns, BCMO1 polymorphisms, and primary lung cancer risk in a Han Chinese population: a case-control study in Southeast China.

Background: We investigated whether BCMO1 variants and dietary patterns are associated with lung cancer risk.

Methods: Case-control study including 1166 lung cancer cases and 1179 frequency matched controls was conducted for three BCMO1 variants (rs6564851, rs12934922, and rs7501331) and four dietary patterns were investigated. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs).

Single nucleotide polymorphisms of the NF-κB and STAT3 signaling pathway genes predict lung cancer prognosis in a Chinese Han population.

Inflammation contributes to human carcinogenesis and cancer progression. This study selected and analyzed single nucleotide polymorphisms (SNPs) of the NF-κB and STAT3 signaling pathway genes for associations with prognosis in 1,165 lung cancer patients from a Chinese Han population. The data showed that eight SNPs (i.
