  Reversibility of chemotherapy-related liver injury

Chemotherapy-associated liver injury (CALI) increases the risk of liver resection and may prejudice further surgery and chemotherapy. The reversibility of CALI is therefore important; however, no data concerning this are available. This study aimed to retrospectively analyze the reversibility of CALI in patients undergoing liver resection for colorectal metastases.


All resections of colorectal liver metastases after oxaliplatin and/or irinotecan-based chemotherapy were included. First, liver resections were stratified by time between end of chemotherapy and hepatectomy and several possible cut-off values tested. CALI prevalence in various groups was compared. Second, CALI in the two specimens from each patient who had undergone repeat liver resections without interval chemotherapy were compared.


Overall, 524 liver resections in 429 patients were analyzed. The median interval chemotherapy-surgery was 56days (15-1264). CALI prevalence did not differ significantly between groups with a chemotherapy-surgery interval <270days. Grade 2-3 sinusoidal dilatation (SOS, 19.4% vs. 40.0%, p=0.022) and nodular regenerative hyperplasia (NRH, 6.5% vs. 20.1%, p=0.063) occurred less frequently in patients with an interval >270days (n=31); prevalence of steatosis and steatohepatitis was similar in all groups. A chemotherapy-surgery interval >270days was an independent protector against Grade 2-3 SOS (p=0.009). Forty-seven patients had repeat liver resection without interval chemotherapy. CALI differed between surgeries only for a chemotherapy-surgery interval >270days (n=15), Grade 2-3 SOS having regressed in 4/5 patients and NRH in 7/8; whereas steatosis and steatohepatitis had persisted.


CALI persists for a long time after chemotherapy. SOS and NRH regress only after nine months without chemotherapy, whereas steatosis and steatohepatitis persist.


The patients affected by colorectal liver metastases often receive chemotherapy before liver resection, but chemotherapy causes liver injuries that may increase operative risks and reduce tolerance to further chemotherapy. The authors analyzed the reversibility of the liver injuries after the chemotherapy interruption. Liver injuries persist for a long time after chemotherapy. Sinusoidal dilatation and nodular regenerative hyperplasia regress only nine months after the end of chemotherapy, whereas steatosis and steatohepatitis persist even after this long interval.
