The aim of this study is to evaluate the increase of radiation dose administered in patients diagnosed with locally advanced rectal cancer in terms of ypRC with tolerable toxicity, using IMRT (concomitant boost technique).
The hypothesis that arises is an improvement in the proportion of pathological complete responses, resulting therapeutic gain, as a result of a higher dose of radiation delivered to the tumor volume without incurring a higher gastrointestinal toxicity to the patient or surgical complications later, thanks to the use of intensity modulated radiotherapy (concomitant boost technique) that allows us to significantly reduce the administered dose organs at risk.

The highest dose of a biologically active agent given during a chronic study that will not reduce longevity from effects other than carcinogenicity. (from Lewis Dictionary of Toxicology, 1st ed)
Initial drug treatment designed to bring about REMISSION INDUCTION. It is typically a short-term and high-dose drug treatment that is followed by CONSOLIDATION CHEMOTHERAPY and then MAINTENANCE CHEMOTHERAPY.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
