Identification of a tumor-reactive T-cell repertoire in the immune infiltrate of patients with resectable pancreatic ductal adenocarcinoma
The devastating prognosis of patients with resectable pancreatic ductal adenocarcinoma (PDA) presents an urgent need for the development of therapeutic strategies targeting disseminated tumor cells. Until now, T-cell therapy has been scarcely pursued in PDA, due to the prevailing view that it represents a poorly immunogenic tumor.We systematically analyzed T-cell infiltrates in tumor biopsies from 127 patients with resectable PDA by means of immunohistochemistry, flow cytometry, T-cell receptor (TCR) deep-sequencing and functional analysis ofProminent T-cell infiltrates, as well as tertiary lymphoid structures harboring proliferating T-cells, were detected in the vast majority of biopsies f…
Evolution of the immune landscape during progression of pancreatic intraductal papillary mucinous neoplasms to invasive cancer
ABSTRACT: Background: Intraductal papillary mucinous neoplasms (IPMNs) are precursor lesions of pancreatic cancer, which is characterized by an immunosuppressive microenvironment. Yet, the spatial distribution of the immune infiltrate and how it changes during IPMN progression is just beginning to be understood. Methods: We obtained tissue samples from patients who underwent pancreatic surgery for IPMN, and performed comprehensive immunohistochemical analyses to investigate the clinical significance, composition and spatial organization of the immune microenvironment during progression of IPMNs. Survival analysis of pancreatic cancer patients was stratified by tumour infiltrating immune cel…
Survival and recurrence after liver transplantation versus liver resection for hepatocellular carcinoma: a retrospective analysis.
Objective This study compares the results of liver transplantation (LTx) and liver resection (LR) for hepatocellular carcinoma (HCC) to test the widespread hypothesis that LTx is the preferable approach for small HCCs. Summary Background Data With respect to scarcity of donor organs and poor results, LTxs for large HCCs are obsolete. Small HCC transplantations have been reported to result in an excellent survival rate. However, the data of comparative studies are controversial. Methods Patients who were treated curatively by LTx (n = 50) or LR (n = 52) for HCC were included in this retrospective study. Survival and freedom from recurrence were analyzed. Patients were stratified according to…
