BACKGROUND: Identification of a biomarker predicting chemotherapy efficacy in patients with advanced pancreatic cancer (APC) is urgently needed. This study aimed to determine the association between the neutrophil-to-apolipoprotein A1 ratio (NEAPO) and chemotherapy efficacy in APC patients.
METHODS: This retrospective study involved 236 APC patients who underwent first-line chemotherapy, including FOLFIRINOX (FFX), nab-paclitaxel plus gemcitabine (AG), or SOXIRI. Receiver operating characteristic curve analysis was performed to determine the optimal cutoff value of NEAPO, and patients were divided into low and high NEAPO groups. Kaplan-Meier curves and Cox regression analyses were used to evaluate the effect of NEAPO on overall survival (OS) and progression-free survival (PFS).
RESULTS: The optimal cutoff of NEAPO was 4.69. High NEAPO levels were associated with shorter OS (p = 0.046) and PFS (p = 0.001). In the NEAPO low subgroup, the median PFS of SOXIRI was longer than that in AG group (7.2 months vs. 5.5 months, p = 0.029), with no significant difference of PFS between SOXIRI and FFX (p = 0.691). There is a trend but not significant difference in PFS between AG and FFX (p = 0.096). The proportion of disease control rate (DCR) was higher in SOXIRI group. In the NEAPO high subgroup, there was no significant difference in PFS among the three regimens, while the DCR was higher in AG group.
CONCLUSIONS: NEAPO levels were significantly associated with OS, PFS and treatment response in APC patients who underwent chemotherapy and might be a useful biomarker for predicting chemotherapy efficacy.
