No increase in cancer risk for most patients with reflux diseaseReflux disease manifests as acid regurgitation and heartburn and is a known risk factor for oesophageal cancer. However, a new study published in The BMJ by researchers at Karolinska Institutet now reports that the majority of patients do not have a higher risk of cancer. A large-scale study from three Nordic countries shows that the cancer risk is only elevated in patients whom gastroscopy reveals to have changes in the oesophageal mucosa.

Immunotherapy is an effective form of therapy for different types of cancer. However, for pancreatic cancer, its effect is limited and differs between men and women. Researchers at Karolinska Institutet have now found a possible explanation for this sex difference. The study, which is published in Cancer Research, reveals the presence of an immune cell in women with pancreatic cancer that obstructs the body’s immune response. The results can pave the way for a more sex-specific treatment.

Cool room temperature inhibited cancer growth in miceTurning down the thermostat seems to make it harder for cancer cells to grow, according to a study in mice by researchers at Karolinska Institutet. The study, published in the journal Nature, found that chilly temperatures activate heat-producing brown fat that consumes the sugars the tumors need to thrive. Similar metabolic mechanisms were found in a cancer patient exposed to a lowered room temperature.
