Oxaliplatin‑induced changes in splenic volume and liver fibrosis indices: retrospective analyses of colon cancer patients receiving adjuvant chemotherapy.

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%,
