Dose-escalation Trial of Preoperative Radiotherapy and Concurrent Chemotherapy in Locally Advanced Rectal Cancer

2016-11-17 11:38:21 | BioPortfolio


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.

Medical and Biotech [MESH] Definitions

CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.

A treatment schedule in which the total dose of radiation is divided into large doses.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

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.
