Clinical impact of postoperative prognostic nutritional index in colorectal cancer patients undergoing adjuvant chemotherapy.

ABSTRACT: Preoperative Prognostic Nutritional Index (PNI) could be a crucial factor for the prognosis of colorectal cancer (CRC). However, the clinical impact of postoperative PNI is still unclear, and there have been no reports on the significance of postoperative PNI in patients undergoing adjuvant chemotherapy (AC). We retrospectively analysed 227 consecutive patients who underwent AC after radical surgery for high-risk stage II or stage III CRC. PNI value was calculated before radical surgery and before the introduction of AC. In our study, patients with a low PNI value before surgery showed significantly poorer long-term outcomes than those with a high PNI value. Next, we divided the patients into four groups: patients with a high PNI value before surgery and remained after surgery (Group High-
