OBJECTIVE Resection of a primary colorectal carcinoma (CRC) can be accompanied by rapid outgrowth of liver metastases, suggesting a role for angiogenesis. The aim of this study is to investigate whether the presence of a primary CRC is associated with changes in angiogenic status and proliferation/apoptotic rate in synchronous liver metastases and/or adjacent liver parenchyma. METHODS Gene ex...
Approximately 50% of patients with primary colorectal carcinoma develop liver metastases. This study investigates the possible molecular discrepancies between cancer (pCRC) and their respective
Consistent liver metastases in animal models is generally observed only with certain cancer cell lines. With the aim of improving on existing animal models of liver metastases, we hypothesized that cancer cells encased in 300 Mm microcapsules, mimicking micrometastatic foci, might be effective seeds of liver metastases. A total of 3,000 microcapsules, containing 700 to 1,500 viable cells/capsul...
PURPOSE Reports have suggested that metastatic site is an important predictor of overall survival (OS) in men with metastatic castration-resistant prostate cancer (mCRPC), but these were based on a limited number of patients. We investigate the impact of site of metastases on OS of a substantial sample of men with mCRPC who received docetaxel chemotherapy in nine phase III trials. PATIENTS AN...
AIMS AND BACKGROUND We demonstrated that colorectal liver metastases considered in complete response after intra-arterial floxuridine-based chemotherapy had recurred in situ. METHODS AND STUDY DESIGN One hundred and six colorectal liver metastases disappeared after intra-arterial chemotherapy. Persistent macroscopic disease was observed at surgery at the site of 52 of 106 liver metastases, ev...
Colorectal cancer (CRC) is one of the most common cancer diseases worldwide. One in 4 patients with CRC will have a disseminated disease at the time of diagnosis and often in the form of synchronous liver metastases. Studies suggest that up to 30% of patients have non-recognized hepatic metastases during primary surgery for CRC. Intraoperative ultrasonography examination (IOUS) of the liver to ...
BACKGROUND The role of liver resection for non-colorectal, non-neuroendocrine, non-sarcoma (NCNNNS) metastases is ill-defined. This study aimed to examine the oncologic outcomes of liver resection in such patients. METHODS A retrospective analysis of liver resection for NCNNNS metastases was performed at two large centers. Liver resection was offered selectively in patients with stable diseas...
BACKGROUND Colorectal carcinomas were studied regarding early proof of liver metastases through determination of K-ras mutations. PATIENTS AND METHODS Seventy-seven colorectal carcinomas were investigated for the presence of point mutations in codon 12 and 13 of the K-ras gene, using single-strand conformation polymorphism (SSCP) analysis and direct sequencing. RESULTS Twenty-six carcinomas...
gastrointestinal stromal tumors are mesenchymal neoplasms of the gastrointesti- nal tract that originate from all areas of the gastrointestinal tract. metastases to the liver, peritoneum, bones, lungs and soft tissues have been reported. we present the case of a 47- year-old woman with rectal gastrointestinal stromal tumor that underwent wide local excision. she was treated with imatinib for a ...
Prostate cancer metastases are a major cause of death among men. Almost all men who died from prostate previously had to the bones or other sites, including lymph nodes, lung, and liver. Urethral one rarest locations metastases. In this clinical case, we present case man recurrence prostatic adenocarcinoma 36 months after radical prostatectomy; diagnosis treatment patient described.
