Surgical resection is the only curative modality for colorectal liver metastases (CLM), and the pattern of recurrences after resection affects survival. In a prospective study of liver transplantation (Lt) for nonresectable CLM we have shown a 5-year overall survival rate of 60 %, but 19 of 21 experienced recurrence. This study reports the pattern of(More)
Naturally occurring regulatory T cells (Tregs) maintain self tolerance by dominant suppression of potentially self-reactive T cells in peripheral tissues. However, the activation requirements, the temporal aspects of the suppressive activity, and mode of action of human Tregs are subjects of controversy. In this study, we show that Tregs display significant(More)
OBJECTIVE The objective of this pilot study was to investigate the potential for long-term overall survival (OS) after liver transplantation for colorectal liver metastases (CLMs). BACKGROUND Patients with nonresectable CLMs have poor prognosis, and few survive beyond 5 years. CLMs are currently considered an absolute contraindication for liver(More)
OBJECTIVE The primary objective was to compare overall survival (OS) in patients with colorectal cancer (CRC) with nonresectable liver-only metastases treated by liver transplantation or chemotherapy. BACKGROUND CRC is the third most common cancer worldwide. About 50% of patients will develop metastatic disease primarily to the liver and the lung. The(More)
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(More)
OBJECTIVE Selected patients with nonresectable colorectal liver metastases benefit from liver transplantation and have acceptable 5-year survival rates. However, allocating full-sized grafts to this group of patients is difficult due to the scarcity of grafts. This could be improved by utilizing small partial grafts, which mandates effective strategies to(More)
Most centers are reluctant to accept expanded criteria donors above 70 to 75 years of age. We accepted kidneys from a 90-year-old male and report the 1-year outcome. The kidneys were used as single transplants and both had immediate graft function. Recipient A was a 71-year-old male, with cold ischemia time of 4 hours 49 minutes. One rejection was(More)
PURPOSE To study quality of life (QoL) in patients with liver metastases from colorectal carcinoma (CRC) following liver transplantation (Ltx). METHODS Ten patients participated in a prospective explorative pilot study. Inclusion criteria were nonresectable liver-only metastases determined by CT/MRI-, PET/CT- scans and colonoscopy, and ECOG 0-1. Primary(More)
Pancreatic ductal adenocarcinoma (PDAC) is highly infiltrated by CD4(+)T cells that express RORγt and IL-17 (TH17). Compelling evidence from the tumor microenvironment suggest that regulatory T cells (Treg) contribute to TH17 mediated inflammation. Concurrently, PDAC patients have elevated levels of pro-inflammatory cytokines that may lead to TH17(More)
Human CD4(+)CD25(hi)FOXP3(+) regulatory T cells maintain immunologic tolerance and prevent autoimmune and inflammatory immune responses. Regulatory T cells undergo a similar activation cycle as conventional CD4(+) T cells upon antigen stimulation. Here, we demonstrate that T cell receptors and costimulation are required to activate the regulatory T cell(More)
