Study paves the way for cancer treatments that might prevent relapses after radiotherapy

(Fundação de Amparo Pesquisa do Estado de São Paulo) Brazilian researchers suggest that the combination of drugs that block a protein called PAF-R may increase radiotherapy's killing of tumor cells by one third. The experiments that proved the involvement of PAF-R in tumor repopulation were performed with human oral cancer cells and murine cervical cancer cells, in which radiotherapy is usually preferred.
