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.

Postoperative dynamic survival of gastric cancer patients: A multi-institutional, international analysis of 22 265 patients.

Background: How to best evaluate the disease-specific survival (DSS) of gastric cancer (GC) survivors over time is unclear.

Methods: Clinicopathological data from 22 265 patients who underwent curative intend resection for GC were retrospectively analyzed. Changes in the patients' 3-year conditional disease-specific survival (CS3) were analyzed.

Association between mir-24 and mir-378 in formalin-fixed paraffin-embedded tissues of breast cancer.

Background: MiR-24/378 is thought to be onco-miRNAs for their ability of enhancing tumor growth. The objective of this study was to evaluate the potential predictive value of miR-24/378 expression in formalin-fixed paraffin-embedded tissues of breast cancer patients.

Methods: The expression of miR-24/378 was examined in 101 breast cancer patients and 40 controls using real-time quantitative PCR.

Over-expression of miR-98 in FFPE tissues might serve as a valuable source for biomarker discovery in breast cancer patients.

The miR-98 is thought to be associated with various cancers. This study was to evaluate the potential predictive value of miR-98 expression in formalin-fixed paraffin-embedded tissue of breast cancer patients. The expression levels of miR-98 were examined in 98 breast cancer patients and 40 cancer-free controls using real-time quantitative PCR.

Expression level of miR-93 in formalin-fixed paraffin-embedded tissues of breast cancer patients.

MiR-93 is thought to be an onco-miRNA for its capabilities of enhancing tumor growth. The objective of this study was to evaluate the potential predictive value of miR-93 expression in formalin-fixed paraffin-embedded (FFPE) tissues of breast cancer patients. The expression of miR-93 was examined in 101 breast cancer patients and 40 controls using real-time quantitative PCR.
