Scientists bring cancer care from genome sequencing 'one step closer'

Scientists have said they are "one step closer" to making whole-genome sequencing a part of direct patient care in cancer cases.

Researchers at Mayo Clinic and the Translational Genomics Research Institute revealed they have successfully completed the successful identification of a single patient's entire DNA genetic code for normal and cancerous cells.

The experts were able to compare DNA inside a tumour to normal strands, with mutations providing doctors with information on how best to approach treatment.

Mitesh Borad, assistant professor of medicine and oncology specialist at Mayo Clinic, said: "No one thought that this would be possible this soon and the key now is to combine all medical and scientific information together."

However, he admitted the developments are still in the "very early" stages.

Earlier this month, scientists at the University of Helsinki announced that photodynamic therapy using a light-activated cytotoxic drug may help prevent metastasis by eradicating tumour-associated lymphatic vessels and the cancerous cells they contain.
