Quantified MRI and 25OH-VitD3 can be used as effective biomarkers for patients with neoadjuvant chemotherapy-induced liver injury in CRCLM?

Abstract

Background: To evaluate proton-density fat-fraction (PDFF) and intravoxel incoherent motion (IVIM) techniques, and human 25-hydroxyvitamin D3 (25OH-VitD3) levels, as potential biomarkers in patients with colorectal cancer with liver metastasis (CRCLM). Changes were compared with those related to chemotherapy-associated steatohepatitis (CASH) and sinusoidal obstruction syndrome (SOS). Methods: 63 patients with pathologically confirmed colorectal adenocarcinoma received 4-6 courses of NC before liver resection and underwent magnetic resonance imaging (MRI) with iterative decomposition of water and fat with echo asymmetry and least-squares estimation quantification and IVIM sequences. Blood samples were analyzed using CTCAE. Pathological changes of liver tissues outside the metastases were assessed as the gold standard, and receiver operating characteristic (ROC) curves were analyzed. Results: 16 cases had CASH liver injury, 14 cases had SOS changes, and 4 cases had CASH and SOS, and 7 showed no significant changes. Consistency between biochemical indices and pathological findings was poor (kappa = 0.246, p = 0.005). The areas under the ROC curve (AUCs) of ALT, AST, ALP, GGT, and TBIL were 0.571-0.691. AUCs of D, FF, and 25OH-VitD3 exceeded 0.8; when considering these markers together, sensitivity was 85.29% and specificity was 93.13%. ANOVA showed statistically significant differences among D, FF, and 25OH-VitD3 for different grades of liver injury (F = 4.64-26.5, p = 0.000-0.016). Conclusions: D, FF, and 25OH-VitD3 are biomarkers for accurate prediction of NC-induced liver injury in patients with CRCLM, while FF and 25OH-VitD3 might be beneficial to distinguish liver injury grades. Trial registration: Current Trials was retrospectively registered as ChiCTR1800015242 at Chinese Clinical Trial Registry on March 16, 2018.

Noninvasive Assessment of APAP (N‐acetyl‐p‐aminophenol)‐Induced Hepatotoxicity Using Multiple MRI Parameters in an Experimental Rat Model

“…9, 10 Yang et al 7 found that the reduction rate of T1 relaxation time on hepatobiliary phase (HBP) strongly correlated with the severity of oxaliplatin-induced liver injury. In addition, intravoxel incoherent motion (IVIM) has been used to assess liver injury caused by hepatitis B virus, 11 chemotherapy, 12 or intestinal ischemia-reperfusion. 13 Both studies showed that diffusion or perfusion parameters had potential in evaluating the severity of liver injury.…”
