Effectiveness analysis of neoadjuvant chemotherapy in the treatment of locally advanced colon cancer. ELECLA trial


Participants in this study selected patients according to homogeneous inclusion criteria and will be treated either with a uniform protocol of neoadjuvant chemotherapy, surgery and complementary chemotherapy (intervention group), or with the standard scheme of postoperative surgery and chemotherapy (control group ). All patients will be studied basally through clinical examinations and radiological and endoscopic tests usually used to reach the diagnosis of Locally Advanced Colon Cancer . In the group of patients receiving neoadjuvant treatment, the CT scan will be repeated after the completion of preoperative chemotherapy to restage the disease and quantify the degree of tumor response.

Finally, the project tries to determine whether the neoadjuvant treatment scheme increases disease-free survival (SLE) at 2 and 5 years and overall survival (OS) at 5 years. Likewise, the toxicity derived from chemotherapy treatment and perioperative morbidity and mortality will be analyzed to evaluate the feasibility and safety of the therapeutic procedure. The rate of completion of chemotherapy in both groups will also be compared.
