Patients with non‐resectable colorectal cancer receiving palliative chemotherapy has a 5‐year overall survival of about 10%. Liver transplantation provided Kaplan‐Meier estimated 5‐year overall survival of up to 83%. The objective of the study was to evaluate the ability of different scoring systems to warrant long term overall survival after liver transplantation. Colorectal cancer patients with non‐resectable liver only metastases determined by CT/MRI/PET‐CT scans from two prospective studies (SECA‐I and II) were included. All included patients had previously received chemotherapy. PET/CT was performed within 90 days of the liver transplantation. Overall survival, disease‐free survival and survival after relapse based on the following scoring systems; Fong Clinical Risk Score, total PET liver uptake (metabolic tumor volume) and Oslo Score were compared. At median follow‐up of 85 months of patients alive, Kaplan‐Meier overall survival at five years were 100%, 78% and 67%, in patients with Fong Clinical Risk Score 0‐2, metabolic tumor volume‐low group and Oslo Score 0‐2, respectively. Median overall survival was 101 months, 68 months and 65 months in Fong Clinical Risk Score 0‐2, metabolic tumor volume‐low and Oslo Score 0‐2. These selection criteria may be used to obtain 5‐year overall survival rates comparable to other indications for liver transplantation.

Importance: Liver transplant for colorectal cancer with liver metastases was abandoned in the 1990s due to poor overall survival. From 2006, liver transplant for in nonresectable colorectal liver metastases has been reexamined through different prospective trials.Objective: To determine predictive factors for transplant long-term survival and cure after liver transplant.Design, Setting, and Participants: This was a prospective, nonrandomized controlled cohort study derived from different clinical trials on liver transplant for colorectal liver metastases from 2006 to 2020 at Oslo University Hospital. The trials differed in prognostic inclusion criteria, but the design was otherwise identical regarding follow-up scheme to determine disease recurrence, overall survival, and survival after relapse. Final data analysis was performed on December 31, 2021. All patients with colorectal liver metastases from comparable prospective liver transplant studies were included.Exposure: Liver transplant.Main outcomes and measures: Disease-free survival, overall survival, and survival time after recurrence were determined in all participants.Results: A total of 61 patients (median [range] age, 57.8 [28.7-71.1] years; 35 male [57.4%]) underwent liver transplant at Oslo University Hospital. Posttransplant observation time ranged from 16 to 165 months, and no patient was lost to follow-up. Median disease-free period, overall survival, and survival after relapse were 11.8 (95% CI, 9.3-14.2) months, 60.3 (95% CI, 44.3-76.4) months, and 37.1 (95% CI, 4.6-69.5) months, respectively. Negative predictive factors for overall survival included the following: largest tumor size greater than 5.5 cm (median OS, 25.3 months; 95% CI, 15.8-34.8 months; P <.001), progressive disease while receiving chemotherapy (median OS, 39.8 months; 95% CI, 28.8-50.7 months; P = .02), plasma carcinoembryonic antigen values greater than 80 μg/L (median OS, 26.6 months; 95% CI, 22.7-30.6 months; P <.001), liver metabolic tumor volume on positron emission tomography of greater than 70 cm3 (26.6 months; 95% CI, 11.8-41.5 months; P <.001), primary tumor in the ascending colon (17.9 months; 95% CI, 0-37.5 months; P <.001), tumor burden score of 9 or higher (23.3 months; 95% CI, 19.2-27.4 months; P = .02), and 9 or more liver lesions (42.5 months; 95% CI, 17.2-67.8 months; P = .02). An Oslo score of 0 or Fong Clinical Risk Score of 1 yielded 10-year survival of 88.9% and 80.0%, respectively.Conclusions and relevance: Results of this nonrandomized controlled trial suggest that selected patients with liver-only metastases and favorable pretransplant prognostic scoring had long-term survival comparable with conventional indications for liver transplant, thus providing a potential curative treatment option in patients otherwise offered only palliative care.

Pancreatic cancer is the fourth leading cause of cancer-related death. While surgical resection remains the foundation for potentially curative treatment, survival benefit is achieved with adjuvant oncological treatment. Thus, completion of multimodality treatment (surgical resection and (neo)adjuvant chemotherapy) to all patients and early treatment of micrometastatic disease is the ideal goal. NorPACT–1 aims to test the hypothesis that overall mortality at one year after allocation of treatment can be reduced with neoadjuvant chemotherapy in surgically treated patients with resectable pancreatic cancer. The NorPACT– 1 is a multicentre, randomized controlled phase III trial organized by the Norwegian Gastrointestinal Cancer Group for Hepato-Pancreato-Biliary cancer. Patients with resectable adenocarcinoma of the pancreatic head are randomized to receive either surgery first (Group 1: SF/control) or neoadjuvant chemotherapy (Group 2: NT/intervention) with four cycles FOLFIRINOX followed by resection. Both groups receive adjuvant chemotherapy with gemicitabine and capecitabine (six cycles in Group 1, four cycles in Group 2). In total 90 patients will be randomized in all the five Norwegian university hospitals performing pancreatic surgery. Primary endpoint is overall mortality at one year following commencement of treatment for those who ultimately undergo resection. Secondary endpoints are overall survival after date of randomization (intention to treat), overall survival after resection, disease-free survival, histopathological response, complication rates after surgery, feasibility of neoadjuvant and adjuvant chemotherapy, completion rates of all parts of multimodal treatment, and quality-of-life. Bolt-on to the study is a translational research program that aims at identifying factors that are predictive of response to NT, the risk of distant cancer spread, and patient outcome. NorPACT– 1 is designed to investigate the additional benefit of NT compared to standard treatment only (surgery + adjuvant chemotherapy) for resectable cancer of the pancreatic head to decrease early mortality (within one year) in resected patients.

Background Patients with metastatic colorectal cancer receiving palliative chemotherapy have a 5‐year survival rate of approximately 10 per cent. Liver transplantation using strict selection criteria in patients with colorectal cancer and unresectable liver‐only disease will result in a 5‐year survival rate of 56–83 per cent. The aim of this study was to evaluate survival of patients with colorectal liver metastases (CRLM) after liver transplantation using extended criteria for both patients and donors. Methods This was a prospective single‐arm study. Patients with synchronous unresectable CRLM who were not suitable for arms A, B or C of the SEcondary CAncer (SECA) II study who had undergone radical resection of the primary tumour and received chemotherapy were included; they underwent liver transplantation with extended criteria donor grafts. Patients who had resectable pulmonary metastases were eligible for inclusion. The main exclusion criteria were BMI above 30 kg/m2 and liver metastases larger than 10 cm. Survival was estimated using Kaplan–Meier analysis. Results Ten patients (median age 54 years; 3 women) were included. They had an extensive liver tumour load with a median of 20 (range 1–45) lesions; the median size of the largest lesion was 59 (range 15–94) mm. Eight patients had (y)pN2 disease, six had poorly differentiated or signet ring cell‐differentiated primary tumours, and five had primary tumour in the ascending colon. The median Fong clinical risk score was 3 (range 2–5) and the median Oslo score was 1 (range 1–4). The median plasma carcinoembryonic antigen level was 4·3 (range 2–4346) μg/l. Median disease‐free and overall survival was 4 and 18 months respectively. Conclusion Patients with unresectable liver‐only CRLM undergoing liver transplantation with extended patient and donor criteria have relatively short overall survival.
