Studies this quarter on coffee and cancer included:
A literature review and meta-analysis of observational studies by S Caini et al. investigated the association between coffee and tea intake and non-melanoma skin cancer risk. Findings suggest that coffee intake exerts a moderate protective effect against basal cell cancer development, probably through the biological effect of caffeine; however the authors suggest reviewing these results with caution and that they should be verified in randomised clinical trials.

Y Xie et al. conducted a systematic analysis of relevant population studies to derive a more precise estimation of the association between coffee consumption and gastric cancer. The meta-analysis indicated that an increase in coffee consumption, up to 4 cups per day, might be associated with a decreased risk of gastric cancer.

A meta-analysis of 11 relevant studies performed by K Bai et al. considered the growing evidence that coffee consumption is inversely i.e. favourably associated with a reduced risk of hepatocellular carcinoma. The findings confirmed the suggested association, detecting the protective effect among a healthy population and patients with chronic liver diseases, suggesting that coffee consumption may also prevent the development of liver cirrhosis.

S F Peisch et al. conducted a review and summary of evidence on the role of diet and lifestyle factors and prostate cancer progression, with a specific focus on habits after diagnosis and the risk of subsequent disease recurrence, progression, or death. The study found that a variety of dietary and lifestyle factors appear to affect prostate cancer progression. In particular, exercise and smoking cessation may reduce the risk of prostate cancer progression and death, although further investigation is required.

A cohort study by T Ogawa et al. in a Japanese population evaluated the association between coffee and green tea intake, and brain tumour risk. Results suggest that coffee consumption may reduce the risk of brain tumour, including that of glioma, a malignant tumour of the glial tissue of the nervous system.

Further studies to note from this quarter include:
A C Purdue-Smithe et al. evaluated the association between total caffeine, coffee, and tea intake and the development of PMS in a case-control study nested within the prospective Nurses’ Health Study II. Findings suggest that caffeine intake is not associated with PMS, and that current recommendations for women to reduce caffeine intake may not help prevent the development of PMS.

M C Tollanes et al. investigated the association between caffeine intake by pregnant women and risk of cerebral palsy (CP) in vulnerable low-birth-weight neonates. The study was based on The Norwegian Mother and Child Cohort Study, comprising more than 100,000 live-born children, of whom 222 were subsequently diagnosed with CP. Results suggested maternal total daily caffeine consumption before and during pregnancy was not associated with CP risk in children, but that an increased risk observed with caffeinated soft drinks warrants further investigation.
