Background:
Gastric cancer can recur soon after treatment. We evaluated the prognostic nutritional index (PNI), a predictor of postoperative complications, and examined the association of PNI with progression and recurrence of gastric cancer.
Methods:
We retrospectively investigated data from 697 patients who had undergone surgery for gastric carcinoma (excluding those with stage IV disease) and analyzed associations of age, sex, performance status (PS), American Society of Anesthesiologists (ASA) classification, diabetes, depth of main tumor (T), lymph node metastasis, postoperative complications, recurrence, and survival with PNI. We also performed multivariate analysis to identify factors associated with survival.
Results:
PNI significantly decreased with age and was significantly lower in women. PNI was significantly positively correlated with PS. PNI was significantly lower for ≥T2 cancers and in patients with lymph node metastasis. There was no association between postoperative complications and PNI. PNI was significantly lower for patients who developed recurrence than for those who did not. The survival rate was examined for groups with a PNI of ≥45 (high PNI) and <45 (low PNI). Both 5-year overall survival (OS) and cancer-specific survival (CS) were significantly worse for the low PNI group. Multivariate analysis showed that PNI was an independent predictor of OS and CS.
Conclusions:
PNI was associated with progression and recurrence of gastric cancer.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
