A new study published in the New England Journal of Medicine, funded by Cancer Research UK, has found that the risk of breast cancer recurring persists undiminished for at least 20 years after diagnosis, suggesting that hormonal treatments should continue for even longer to reduce the risk of late recurrence.

The Early Breast Cancer Trialists’ Collaborative Group, an international team of investigators based at the University of Oxford, pooled data from over 60,000 women in 88 clinical trials who had been diagnosed with estrogen receptor positive breast cancer between 1976 and 2011, and prescribed anti-estrogen therapy, such as tamoxifen or an aromatase inhibitor, for 5 years. These women who had no recurrence in the first 5 years, then stopped treatment and their progress was followed for up to 15 further years.

New evidence for how our brains handle surprise

A new study from the Bruno Group is challenging our perceptions of how the different regions of the cerebral cortex function. A group of ‘quiet’ cells in the somatosensory cortex that rarely respond to touch have been found to react mainly to surprising circumstances. The results suggest their function is not necessarily driven by touch, but may indicate an important and previously unidentified role across all the major cortices.

Language learning difficulties in children linked to brain differences

A new study using MRI has revealed structural brain changes in children with developmental language disorder (DLD), a common but under-recognised difficulty in language learning. Children with DLD aged 10-15 showed reduced levels of myelin in areas of the brain associated with speaking and listening to others, and areas involved in learning new skills. This finding is a significant advance in our understanding of DLD and these brain differences may explain the poorer language outcomes in this group.
