Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) negatively regulates the phosphoinositide-3-kinase (PI3K) signaling pathway. In colorectal cancer (CRC), observed frequencies of loss of PTEN expression, concordant expression in primary tumors and metastases, and the association of PTEN status with outcome vary markedly by detection method. We determined the degree to which PTEN ...

We describe a simple, rapid, and reproducible ion exchange mini-column chromatographic method for the quantitative measurement of biliary alkaline phosphatase in plasma. We have used this method to evaluate a cellulose acetate electrophoretic method, which was used to assess the value of measuring biliary alkaline phosphatase in 85 patients with breast cancer investigated for possible hepatic m...

UNLABELLED The aim of the present study was to evaluate the effectiveness and safety of hepatic re-resection for breast cancer liver metastases. PATIENTS AND METHODS Between January 2004 and December 2014 seven patients were submitted to liver re-resection for breast cancer liver metastases at our Center. The main inclusion criteria were presence of isolated liver metastases and absence of sy...

PURPOSE To correlate TP53 mutations with angiogenic status of the tumor and prognosis after liver surgery in patients with colorectal liver metastases and to correlate immunohistochemical staining of p53 protein with TP53 gene mutations. EXPERIMENTAL DESIGN Tumors of 44 patients with surgically treated colorectal liver metastases were analyzed for (a) TP53 mutations using denaturing gradient ...

INTRODUCTION Hepatic metastases are diagnosed synchronously in 3-14% of patients with gastric cancer, and metachronously in up to 37% of patients following ''curative" gastrectomy. Most patients who have gastric cancer and hepatic metastasis are traditionally treated with palliative chemotherapy. The impact of liver resection is still controversial. We attempted to assess whether liver resectio...

The prognosis of metastatic pancreatic ductal adenocarcinoma (PDAC) is grim, with a median overall survival of under 1 year. In our clinical practice, we observed a few cases of isolated lung metastases from PDAC with unusually long outcomes. We compared these cases in a case-control study of lung-only vs. liver-only metastases from PDAC.From our database, we found 37 cases of lung-only metasta...

INTRODUCTION Adenoid cystic carcinoma (ACC) of the lacrimal gland is rare but with high recurrence rates and late metastases. They occasionally metastasise via haematogenous spread to lungs, brain and bone. Liver is a rare site of metastasis and is usually present with disseminated disease. PRESENTATION OF CASE A 42 year old lady, a known case of adenoid cystic carcinoma of the lacrimal gland...

Morphological features of lesions conforming to the description of solitary necrotic nodules of the liver were compared with liver haemangiomata and necrotic tumour metastases in the liver. An origin in haemangiomata is confirmed for most of the lesions studied, although the necrotic nodule may represent the end stage of a variety of lesions. These lesions are usually benign, although necrotic ...

Purpose: 1) to compare the survival of patients with colorectal liver metastases who underwent resection as the primary treatment against patients who had chemotherapy as the primary treatment; 2) to compare the survival in patients with recurrent inoperable liver metastases (after resection) treated with Oxaliplatin or Irinotecan against those patients with inoperable recurrence who were treat...

Liver metastases occur in 46-93% of patients with neuroendocrine neoplasms (NENs). Presence and extension of liver metastases are considered important prognostic factors, as they may significantly impair the patient's quality of life, because of either tumor bulk or hormonal hypersecretion. Therapies for NEN liver metastases include surgical resection, liver transplantation, chemotherapy and bi...
