Breakthrough in understanding lung cancer vulnerabilities points the way to new targeted therapy
04 Oct 2012
More effective treatments for one of the deadliest forms of cancer are one step closer thanks to groundbreaking research from an international collaborative study.
Scientists from the Universities of Sheffield and Cologne have identified the dependencies of multiple Small Cell Lung Cancer (SCLC) types – paving the way for clinical trials of new targeted treatments which could revolutionise the current approach.
Around 40,000 people are diagnosed annually with lung cancer in the UK, and SCLC accounts for nearly one in five of all these cases.
Unfortunately, the prognosis for SCLC patients is very bleak – two thirds of people are diagnosed in the late stages of the disease when the five year survival rate with current treatments is less than five per cent.
But now researchers have discovered that survival of SCLC cells grown from human tumours relies upon a protein called Aurora kinase.
This finding, published on Monday in the journal, Proceeding of the National Academy of Sciences of the United States of America (PNAS), suggests that 'targetted' therapeutic strategies should focus on testing Aurora kinase inhibitors, several of which have already been developed by pharmaceutical companies.
