Abstract
The aim of our study was to evaluate the association between increased splenic volume (SV) and liver fibrosis indices in colon cancer patients receiving oxaliplatin-based adjuvant chemotherapy. Patients who received adjuvant oxaliplatin-based regimens with the diagnosis of stage II and III colon cancer were evaluated. Splenic volume measurements, liver function tests, platelet count, and non-invasive liver fibrosis indices [NAFLD fibrosis score (NFS), AST to platelet ratio (APRI), and Fibrosis-4 (FIB-4)] were measured before and after treatment. A 30% increase in SV after chemotherapy compared to baseline was considered increased SV. The rate of increase in SV was 57.7% in the whole group. An increase in SV was shown at a higher rate in patients treated with capecitabine and oxaliplatin (CAPOX) than those treated with 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) (66.3% vs. 36.8%, p = 0.002). Furthermore, the CAPOX regimen (OR: 2.831, 95% CI: 1.125-7.121; p = 0.027), and higher post-treatment FIB-4 score (OR: 3.779; 95% CI:1.537- 9.294, p = 0.004) were determined as independent risk factors for the increased SV. Our study revealed that increased SV had a significant association with higher FIB-4 score in patients treated with oxaliplatin-based chemotherapy.
