Association between primary tumor characteristics and histopathological growth pattern of liver metastases in colorectal cancer

Histopathological Growth Pattern, Proteolysis and Angiogenesis in Chemonaive Patients Resected for Multiple Colorectal Liver Metastases

The purpose of this study was to characterise growth patterns, proteolysis, and angiogenesis in colorectal liver metastases from chemonaive patients with multiple liver metastases. Twenty-four patients were included in the study, resected for a median of 2.6 metastases. The growth pattern distribution was 25.8% desmoplastic, 33.9% pushing, and 21% replacement. In 20 patients, identical growth p...

Colorectal cancer liver metastases organoids retain characteristics of original tumor and acquire chemotherapy resistance

BACKGROUND Colorectal cancer (CRC) liver metastasis is highly unfavorable for patient outcome and is a leading cause of cancer-related death. Pre-clinical research of CRC liver metastasis predominately utilizes CRC cell lines grown in tissue culture. Here, we demonstrate that CRC liver metastases organoids derived from human specimens recapitulate some aspects of human disease. METHODS Human ...

Association of CD166 expression with clinicopathologic characteristics of colorectal cancer

Histopathological findings in colorectal liver metastases after electrochemotherapy

Electrochemotherapy of colorectal liver metastases has been proven to be feasible, safe and effective in a phase I/II study. In that study, a specific group of patients underwent two-stage operation, and the detailed histopathological evaluation of the resected tumors is presented here. Regressive changes in electrochemotherapy-treated liver metastases were evaluated after the second operation ...

Laparoscopic combined colorectal and liver resections for primary colorectal cancer with synchronous liver metastases

BACKGROUNDS/AIMS Synchronous liver metastases (SLMs) are found in 15-25% of patients at the time of diagnosis with colorectal cancer, which is limited to the liver in 30% of patients. Surgical resection is the most effective and potentially curative therapy for metastatic colorectal carcinoma (CRC) of the liver. The comparison of simultaneous resection of primary CRC and synchronous liver metas...
