Pacientes con cáncer de recto localmente avanzado en tratamiento neoadyuvante con quimiorradioterapia en el Instituto Nacional de Cancerología durante 2010

The patients with locally advanced rectal cancer who received neoadjuvant treatment with chemo-radiotherapy in the Instituto Nacional de Cancerología during the year 2010 were, mainly males with a good functional state. The principal chemotherapy scheme employed was 5-fluorouracil and leucovorin in boluses, due to which resectability of the tumour, preservation of the sphincter, and a pathological response in approximately half of the patients, was achieved.
