Peritoneal lymphomatosis is an extremely rare presentation of lymphoma. Due to its relative low frequency, it receives much less attention than peritoneal carcinomatosis. The challenge is to differentiate between lymphomatosis and carcinomatosis, as well as peritoneal tuberculosis or other pathologic entities within the peritoneal cavity based essentially on radiologic features. 18</...

BACKGROUND Clinical significance of microscopic peritoneal carcinomatosis remained unclear. The aim of this study was to evaluate the prognostic value of microscopic peritoneal carcinomatosis in gastric cancer. METHODS From 1996 to 2007, 4426 patients underwent gastrectomy for gastric cancer at Fudan University Shanghai Cancer Center. The clinical and pathological data were reviewed to identi...

Scirrhous gastric cancer is associated with abundant stroma and frequently develops into peritoneal carcinomatosis with malignant ascites. Although malignant ascites is among the most deadly diseases worldwide, its molecular pathogenesis is poorly understood. We investigated the role of hepatocyte growth factor (HGF) in the production of peritoneal carcinomatosis with malignant ascites. We exam...

BACKGROUND The standard of care for colorectal peritoneal carcinomatosis is evolving from chemotherapy to cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with disease limited to the peritoneum. Peritoneal carcinomatosis from colorectal cancer treated with chemotherapy alone results in median survival of 5 to 13 months, whereas CRS with HIPEC for e...

After liver metastases, Peritoneal Carcinomatosis (PC) is the second most frequent cause of death in patients with Colorectal Cancer (CRC), although the precise incidence of Colorectal Cancer Peritoneal Carcinomatosis is not known, as the majority of the diagnostic studies cannot detect the disease in its initial stages, nowadays, the diagnosis of peritoneal carcinomatosis remains a challenge. ...

Peritoneal carcinomatosis is a frequent cause of death in patients with advanced gastric carcinoma. Because chemokines are now considered to play an important role in the metastasis of various malignancies, we hypothesized that they may be involved in the development of peritoneal carcinomatosis by gastric carcinoma. Human gastric carcinoma cell lines, which were all highly efficient in generat...

BACKGROUND Clinical studies of intraperitoneal chemotherapy with paclitaxel in patients of gastric cancer with peritoneal carcinomatosis is well tolerated and effective, and rare cases of metastasis and recurrence have experienced during the treatment. Disseminated carcinomatosis of the bone marrow is highly rare in gastric cancer and associated with a poor prognosis. CASE PRESENTATION A 59-y...

PURPOSE Peritoneal carcinomatosis, often associated with malignant ascites, is the most frequent cause of death in patients with advanced gastric cancer. We previously showed that the CXCR4/CXCL12 axis is involved in the development of peritoneal carcinomatosis from gastric cancer. Here, we investigated whether epidermal growth factor receptor (EGFR) ligands are also involved in the development...
