Chemotherapy resistant ovarian tumour cells "re-grow" cancer - media UK

"Shielded" ovarian cancer cells may survive chemotherapy. "The researchers compared the characteristics of cell lines from the tumour at the time of diagnosis to cell lines from the same patients once the disease had been treated and become resistant." ""By examining the characteristics of ovarian tumours we now think that cells resistant to chemotherapy grow as part of the tumour. This means that when patients have treatment, cells that respond to chemotherapy are destroyed but this leaves behind resistant cells which then form another tumour of completely resistant cells. This seems to explain why successful treatment for relapsed patients is difficult. What needs to be developed now is a therapy designed to target the resistant cells.""
