Since it is common practice to combine irradiation of tumours in humans with drug treatment we have developed procedures that works on nude mice xenotransplanted with human tumour cells. The figure below shows an example in which HCT116/GFP tumours responded to Fluorouracil (5-FU) and the combination of 5-FU and 6 Gy irradiation.
