Dose Escalation Intensity Modulated Radiotherapy treatment

Radiotherapy:

3DCRT treatment (sequential boost) 25 fractions fraction 1,8Gy by administering a total dose of 45 Gy on tumor and lymph nodes and lymph node chains more pelvic margin determined according to protocol.

3 fractions fraction 1,8Gy by sequentially administering an additional dose of tumor and lymph nodes 5,4Gy on more margin.

Chemotherapy:

According to routine clinical practice of the participating centers.

3DCRT treatment (sequential boost)

Radiotherapy:

IMRT treatment (concomitant boost technique) 25 fractions fraction 2,15Gy by administering a total dose of tumor and lymph nodes 53,75Gy on more margin. Simultaneously we will proceed to the irradiation of pelvic lymph node chains according to protocol, a division of 1,8Gy per session until a total dose of 45 Gy.

Chemotherapy:

According to routine clinical practice of the participating centers.

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.
