Widely used anti-nausea drug may interfere with cancer chemotherapy

A widely used anti-nausea drug, dexamethasone, may interfere with cancer chemotherapy. Pretreatment with dexamethasone reduces the ability of paclitaxel and doxorubicin to kill cancer cells by upregulating genes that protect breast cancer cells from cell death.

Study examines role of helicobacter pylori in esophageal cancer development

Researchers found a significant association between H. pylori infection and reduced risk of esophageal adenocarcinoma, but a two-fold increased risk of squamous-cell carcinoma. Gastric atrophy was not linked to disease risk, suggesting an alternative pathway from H. pylori to cancer.

Other highlights in the March 3 issue of JNCI

Researchers found that retinoblastoma survivors are at higher risk of epithelial cancers such as esophagus, stomach, colon, lung, breast, cervix, or prostate, despite low radiation therapy. High folate intake is associated with a lower risk of ovarian cancer, especially among women who consume alcohol.
