A new study in mice suggests that a type of lung cancer could be split into two different diseases based on cells’ molecular fingerprints. The findings suggest that the two types of small cell lung cancer could each be treated differently, according to the researchers from the Huntsman Cancer Institute (HCI) at the University of Utah in the US. Lung cancers are usually defined as either small cell or non-small cell. But these latest results, published in the journal Cancer Cell, suggest there may be further differences among the small cell tumours. Experts believe that the discovery could lead to new forms of treatment that target each specific tumour type. “Survival for small cell lung cancer is low and how we treat the disease hasn’t really changed over the last 20 years. We urgently need new drugs for this hard to treat cancer,” said Dr Alastair Greystoke from the Cancer Research UK Newcastle Cancer Center. “The drugs used in this study have shown some promise in this disease. So these latest findings will help us work out how best to target them in small cell lung cancer.”
