Liver transplantation (Ltx) in patients with nonresectable liver metastases from colorectal carcinoma.
577 Background: Liver resection is considered the only curative treatment of liver metastases (mets) from colo-rectal (CRC) tumors. Ltx is standard of care in selected patients with hepatocellular carcinoma, cholangiocarcinoma and neuroendocrine tumors. Patients with non-resectable liver metastases (mets) from colo-rectal cancer (CRC) receiving palliative chemotherapy have a median survival of about 2 and 1 year from start of 1. and 2. line chemotherapy, respectively. Overall 5 years survival in CRC patients after start of palliative chemotherapy is about 5-10%. In this study we examined overall survival after Ltx in selected CRC patients. The primary endpoint of the study was overall survival at 2 years after Ltx Methods: Major inclusion criteria were: non-resectable liver mets, no extra hepatic disease or local relapse determined by PET/CT scan, CT- or MRI scan and colonoscopy. No mets. on frozen section biopsies at time of surgery, ECOG 0-1, at least one line of chemotherapy for metastatic disease. Postoperative immunosuppresion: mTOR inhibitor (Rapamune), mycofpenolmofetil and tapering doses of prednisolon. Quality of life questionnaire (EORTC-C30) pre Ltx, 3, 6 and 12 months post Ltx. Results: Thirteen men and 8 women with non-resectable liver only CRC liver mets received Ltx in the period of Nov 2006 to March 2011. Median age was 56 years (range 45-65 years). Thirteen patients had colon cancer and 8 patients had rectal cancer. The T-stage of the primary tumor was T2,T3 and T4 in 2, 16 and 3 patients, respectively. N status of the primary tumor was: pN0, pN1 and pN2 all 7 patients. Nine patients had received 1.line chemotherapy and 12 patients had received 2. or 3.line therapy. The median number of liver mets was 8 (range 2-40) and the median size of the largest lesion was 4.5cm (range 2.8-13cm). The patients had good, stabile or increased Global Health Score and Physical Function at all time points after Ltx. Fifteen patients with follow-up of 2 years or more or death within 2 years of Ltx had 2 years overall survival of 87%. Conclusions: Long term survival is obtained after Ltx in selected patients with non-resectable liver mets from CRC. The patients reported good quality of life and physical function after Ltx.
