OBJECTIVE: To investigate the effect of FOLFOX4 neoadjuvant chemotherapy on the non-tumoral liver in patients with metastatic colorectal carcinoma.
METHODS: A large series of surgically resected liver metastases(n=42) was selected and the morphological changes were examined by light and electron microscope. The mRNA and protein levels of connective tissue growth factor (CTGF) expression were detected by semi-quantitative RT-PCR and Western blotting analysis.
RESULTS: Twelve (63.2%) of the 19 post-chemotherapy liver resection specimens had sinusoidal dilatation and hemorrhage. In contrast, 23 livers treated by surgery alone remained normal. Neoadjuvant chemotherapy could significantly enhance the mRNA and protein levels of CTGF expression in hepatic stellate cells.
CONCLUSION: Systemic FOLFOX4 neoadjuvant chemotherapy in metastatic colorectal carcinoma frequently causes morphological injuries involving hepatic microvasculature and induces CTGF expression in hepatic stellate cells to participate in hepatic fibrosis.
