Abstract

Background: Angiogenesis is essential for tumor progression, with vascular endothelial growth factor (VEGF) as a key regulator. A prior single-center study identified VEGF >370 pg/mL on postoperative day 4 (POD4) as a predictor of recurrence in colon cancer (CC). Methods: We conducted a prospective study including 255 patients undergoing curative-intent CC surgery across seven Spanish institutions (NTC04851054). Serum VEGF was measured via ELISA on POD4. Results: After a median follow-up of 34 months, recurrence occurred in 15.7 % of patients. The previously proposed VEGF cutoff was not validated. No significant differences in VEGF were observed between patients with and without recurrence. However, higher VEGF levels were associated with open surgery (p = 0.013) postoperative complications (p < 0.001), with a trend in anastomotic leakage (p = 0.062). Conclusions: VEGF was not predictive of recurrence in this setting but remains a relevant marker of perioperative angiogenic activity, warranting further investigation.
