Besides the lymphatic and haematogenous routes of dissemination,CRC frequently gives rise to transcoelomic spread of tumor cells in the peritoneal cavity,which ultimately leads to peritoneal carcinomatosis(PC). PC is associated with a poor prognosis and bad quality of life for these patients in their terminal stages of disease. A loco-regional treatment modality for PC combining cytoreductive surgery and hyperthermic intraperitoneal peroperative chemotherapy has resulted in promising clinical results. However,this novel approach is associated with significant morbidity and mortality. A comprehensive understanding of the molecular events involved in peritoneal disease spread is paramount in avoiding unnecessary toxicity. The emergence of PC is the result of a molecular crosstalk between cancer cells and host elements,involving several well-defined steps,together known as the peritoneal metastatic cascade. Individual or clumps of tumor cells detach from the primary tumor,gain access to the peritoneal cavity and become susceptible to the regular peritoneal transport. They attach to the distant peritoneum,subsequently invade the subperitoneal space,where angiogenesis sustains proliferation and enables further metastatic growth. These molecular events are not isolated events but rather a continuous and interdependent process. In this manuscript,we review current data regarding the molecular mechanisms underlying the development of colorectal PC,with a special focus on the peritoneum and the role of the surgeon in peritoneal disease spread.展开更多

It is uncommonly arises primarily from the intra-peritoneal cavity. Primary peritoneal MFH with tumor bleeding and rupture is rare. We describe the imaging features of a 70-year-old patient presenting with ruptured hemorrhagic peritoneal MFH at subhepatic area,accompanied by massive hemoperitoneum,mimicking a ruptured pedunculated hepatocellular carcinoma. Computed tomography (CT) revealed a large heterogeneous enhanced subhepatic mass with adjacent liver,gallbladder and colon invasion. Tumor hemorrhage and rupture complicated with peritoneal seeding and massive bloody ascites were also detected. Angiography showed a hypervascular tumor fed by enlarged right hepatic arteries,cystic artery and omental branches of gastroepiploic artery. The patient underwent laparotomy for tumor resection,but the tumor recurred one month after operation. To our knowledge,the CT appearance of ruptured intraperitoneal MFH complicated by hemoperitoneum has not been previously described.展开更多

The genistein treatment was performed for 14 d. The expressions of NF-κB , MMP-2 and MMP-9 on the endometriosis lesions were analyzed by the immunohistochemical technique.Results: The activity of NF-κB in the endometriosis group increased significantly than that of the control group (P<0.05). The expression of MMP-2 or MMP-9 in the endometriosis group increased significantly than that of the control group (P<0.05). Administration of genistein at different doses was capable of significantly reducing the activity of NF-κB compared to that of the endometriosis group (P<0.05), reaching the level comparable to that of the control group at the third highest dose (P>0.05). The four doses of genistein administration were capable of significantly reducing the expression of MMP-2 compared to that of the endometriosis group (P<0.05), reaching an expression comparable to that of the control group for the highest dose (P>0.05). Administration of genistein at different doses was capable of significantly reducing the expression of MMP-9 compared to that of the endometriosis group (P<0.05), reaching the level comparable to that of the control group at the highest dose (P>0.05). Conclusions:Genistein suppresses the expression of MMP-2 and MMP-9 through suppressing NF-κB activity in the peritoneum of murine model of endometriosis.展开更多

The evolution of this thrombosis into a septic thrombophlebitis responsible for persistent septicaemia after a hepatectomy has not been reported to date in the literature. We here report the management of a 54-year-old woman operated for a peripheral cholangiocarcinoma who developed a suppurated thrombophlebitis of the vena cava following a hepatectomy.CASE SUMMARY This patient was operated by left lobectomy extended to segment V with bile duct resection and Roux-en-Y hepaticojejunostomy. After the surgery, she developed Streptococcus anginosus, Escherichia coli, and Enterococcus faecium bacteraemias, as well as Candida albicans fungemia. A computed tomography scan revealed a bilioma which was percutaneously drained. Despite adequate antibiotic therapy,the patient's condition remained septic. A diagnosis of septic thrombophlebitis of the vena cava was made on post-operative day 25. The patient was then operated again for a surgical thrombectomy and complete caval reconstruction with a parietal peritoneum tube graft. Use of the peritoneum as a vascular graft is an inexpensive technique, it is readily and rapidly available, and it allows caval replacement in a septic area. Septic thrombophlebitis of the vena cava after hepatectomy has not been described previously and it warrants being added to the spectrum of potential complications of this procedure.CONCLUSION Septic thrombophlebitis of the vena cava was successfully treated with antibiotic and anticoagulation treatments, prompt surgical thrombectomy and caval reconstruction.展开更多

This is a rare description of tuberculosis in the setting of PSCP.This report illustrates the potential complex nature of malignancies,and emphasizes the need to consider coexistence of malignancy and infection in patients, especially in those with risk factors for malignancy who fail with antibiotic therapy.展开更多
