Abstract:
Objective To investigate the relationship between prognostic nutritional index (PNI) and neutropenia after adjuvant chemotherapy in patients with colorectal cancer. Methods The clinical data of 44 patients with colorectal cancer performed adjuvant chemotherapy in Shunyi District Hospital from December 2014 to January 2018 were retrospectively analyzed, and the patients were divided into group A (grade 0-2 neutropenia) and group B (grade3-4 neutropenia) according to the degree of neutropenia. The serum albumin, peripheral lymphocyte counts, and neutrophil counts within 1 week before chemotherapy were collected, and the PNI was calculated. The chi-square test and rank sum test were used to compare the clinical data, body mass index (BMI), baseline neutrophil count, and PNI between the two groups. Logistic regression analysis was used to analyze the risk factors for neutropenia after chemotherapy. Results The baseline median neutrophil counts and median PNI in group A were 3.17×109/L [(1.38-7.79)×109/L] and 50.40 (37.40-57.05), and in group B were 2.54 ×109/L [(1.22-3.87) ×109/L] and 45.50 (37.95-50.95). The baseline neutrophil counts and PNI in group A were significantly higher than those in group B, the differences between the two groups were statistically significant (Z= -2.085, P= 0.037; Z= -2.615, P= 0.009). Logistic regression analysis showed that PNI was an independent risk factor for neutropenia after chemotherapy (HR=0.803, 95％CI 0.646-0.998, P= 0.048). Conclusion PNI has a certain role in predicting neutropenia after adjuvant chemotherapy in patients with colorectal cancer.
