Postoperative VEGF and Recurrence After Colon Cancer Surgery

Postoperative Serum VEGF Concentration as an Independent Prognostic Factor for Recurrence After Curative Colon Cancer Surgery. Multicentric Study.

The purpose of this trial is to study the relationship between the angiogenic response to surgical aggression, determined through the serum levels of vascular endothelial growth factor (VEGF) on postoperative day four, and the tumor recurrence in patients with colon cancer operated with a curative intention.

DESIGN: Prospective multicentric study.

PARTICIPATION: Colorectal Surgery Units of Hospital del Mar, Barcelona; Hospital Universitari Joan XXIII, Tarragona; Hospital Universitari La Fe, Valencia; Hospital Clínico San Carlos, Madrid; Hospital General de Granollers, Granollers; Hospital Germans Trias i Pujol, Badalona; Athalaia, Xarxa Assistencial Universitària de Manresa, Manresa

STUDY SUBJECTS: 280 consecutive patients with non-metastatic colon cancer in whom a curative intent resection is performed.

DETERMINATIONS: Determination of the proangiogenic cytokine VEGF in serum on the postoperative day four to assess its relationship with oncological results on long-term follow-up.

Inclusion Criteria:

• Patients with colon cancer admitted to the Colorectal Surgery Unit of the centers participating in the study,
• Patients who will undergo elective surgical resection with potentially curative intention

Exclusion Criteria:

• Patients with metastatic disease
• Patients with synchronous colon neoplasia or in the previous five years
• Patients undergoing emergency surgery
• Patients who do not sign the informed consent.
