BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei and appendix tumours are widespread in the world. It is unclear what should be the attitude in elderly patients. METHODS: This retrospective multicenter study collected the database from ten Spanish centers from Spanish Group of Peritoneal Cancer Surgery. The study period was between November 2002 and March 2014. Seventeen patients with age greater than or equal to 75 years with peritoneal carcinomatosis from pseudomyxoma peritonei and appendix tumours met the selection criteria for the study...

Gastric cancer is the third most common cause of cancer death worldwide, although it is not in the top 10 causes of cancer death in Northern America. Due to clear differences in incidence, screening, risk factors, tumor biology, and treatment between gastric cancers from Eastern and Western countries, our treatment is primarily guided by trials from Western countries. Patients undergo an extensive staging evaluation including high-quality CT imaging, endoscopic ultrasound, and diagnostic laparoscopy with peritoneal washings for cytology...

Objective: To study the pathologic features of fallopian tubal epithelium in patients with pelvic high-grade serous carcinoma (HGSC), to investigate its role in pelvic serous carcinogenesis and to reclassify the primary site of HGSC based on recently proposed criteria. Methods: The fallopian tubes in 58 cases of pelvic HGSC (54 cases of ovarian primary, 3 cases of tubal primary, 1 case of peritoneum) and 25 cases of pelvic non-HGSC (5 cases of ovarian low-grade serous cancer, 9 cases of endometrioid cancer, and 11 cases of clear cell ovary carcinoma) were collected from June 2015 to December 2016, and serially examined under light microscope (SEE-FIM protocol)...

Intraperitoneal administration of chemotherapeutics is expected for the treatment of peritoneally disseminated gastric cancer, because of poor migration of the drugs from the systemic circulation to the peritoneal cavity. In this study, for intraperitoneal delivery of cisplatin (CDDP), we developed a hyaluronan (HA)-based hybrid system in which CDDP-loaded HA nanogels were either physically encapsulated in or chemically conjugated to injectable HA hydrogels. Physical encapsulation enabled sustained release of HA nanogels from the HA hydrogel matrix for over a week...

BACKGROUND: Peritoneal metastases (PM), corresponding to tumor implants into the peritoneal cavity, are associated with impaired prognosis and low responsiveness to systemic chemotherapy. A new therapeutic approach has dramatically changed the prognosis of patients with PM from colorectal cancer (CRC), consisting in the association of a complete cytoreductive surgery followed by intraperitoneal chemotherapy associated to hyperthermia (HIPEC). Many drugs have been administered intraperitoneally, but no clear consensus has been approved...

OBJECTIVE: The study's purpose was to assess safety and efficacy of escalating doses of weekly GEN-1 with pegylated liposomal doxorubicin (PLD) in patients with recurrent or persistent epithelial ovarian, fallopian tube or primary peritoneal cancers (EOC). METHODS: Patients had persistent or recurrent platinum-resistant EOC. The trial was a standard 3+3 phase I dose escalation design with patients receiving intravenous PLD 40mg/m(2) (dose level 1 and 2) or 50mg/m(2) (dose level 3) every 28days and intraperitoneal GEN-1 at 24mg/m(2) (dose level 1) or 36mg/m(2) (dose level 2 and 3) on days 1, 8, 15, and 22 of a 28day cycle...

OBJECTIVE: We evaluated the efficacy and safety of aggressive surgery for advanced ovarian cancer at a non-high-volume center. MATERIALS AND METHODS: We evaluated consecutive patients with stage III/IV ovarian, fallopian, and peritoneal cancer undergoing elective aggressive surgery from January 2008 to December 2012, which encompassed the first 5years after implementing an aggressive surgery protocol. After receiving appropriate training for 9months, a gynecological surgical team began performing multi-visceral resections...

INTRODUCTION: Peritoneal dissemination of hepatocellular carcinoma (HCC) is a rare presentation with an incidence of 2-6%. The most common cause of peritoneal deposits is a ruptured HCC that results in tumor spillage into the peritoneal cavity. The overall incidence of spontaneous ruptures of HCC ranges from 5 to 15% and carries a high mortality rate of up to 50%. Other factors influencing peritoneal dissemination are the lymph node metastasis and the direct diaphragmatic invasion and there is no significant association with past history of FNAB, or percutaneous RFA or ethanol injection and lung or adrenal metastasis...

Peritoneal dialysis (PD) therapy substantially requires biomarkers as tools to identify patients who are at the highest risk for PD-related complications and to guide personalized interventions that may improve clinical outcome in the individual patient. In this consensus article, members of the European Training and Research in Peritoneal Dialysis Network (EuTRiPD) review the current status of biomarker research in PD and suggest a selection of biomarkers that can be relevant to the care of PD patients and that are directly accessible in PD effluents...

BACKGROUND: Laparoscopic peritoneal lavage is an alternative to sigmoid resection in Hinchey III diverticulitis (generalized purulent peritonitis). The main limitation of laparoscopic peritoneal lavage is the higher rate of reoperation for persistent sepsis in comparison with sigmoid resection. OBJECTIVE: The purpose of the current study was to identify risk factors for laparoscopic peritoneal lavage failure in patients who have Hinchey III diverticulitis. DESIGN: This was a retrospective multicenter study...

BACKGROUND: Residual disease (RD) after primary debulking surgery (PDS) is one of the main factors driving ovarian cancer prognosis. The primary end point of this study was assessment of the impact that surgery had on survival outcomes for patients with advanced ovarian cancer. METHODS: Data on the effect of newly diagnosed advanced-stage ovarian, tubal, and peritoneal cancers were analyzed during two study periods (T1: 2001-2006 and T2: 2007-2012), in which the concepts of optimal and complete cytoreduction were introduced and implemented...

Unlike most epithelial malignancies which metastasize hematogenously, metastasis of epithelial ovarian cancer (EOC) occurs primarily via transcoelomic dissemination, characterized by exfoliation of cells from the primary tumor, avoidance of detachment-induced cell death (anoikis), movement throughout the peritoneal cavity as individual cells and multi-cellular aggregates (MCAs), adhesion to and disruption of the mesothelial lining of the peritoneum, and submesothelial matrix anchoring and proliferation to generate widely disseminated metastases...

Ovarian cancer is the leading cause of death from gynecological malignancies worldwide, and innate or acquired chemoresistance of ovarian cancer cells is the major cause of therapeutic failure. It has been demonstrated that the concomitant inhibition of Bcl-xL and Mcl-1 anti-apoptotic activities is able to trigger apoptosis in chemoresistant ovarian cancer cells. In this context, siRNA-mediated Bcl‑xL and Mcl-1 inhibition constitutes an appealing strategy by which to eliminate chemoresistant cancer cells...

OBJECTIVE: Asbestos is a known human carcinogen, with evidence for malignant mesothelioma (MM), cancers of lung, ovary, larynx and possibly other organs. MM rates are predicted to increase with a power of time since first exposure (TSFE), but the possible long-term attenuation of the trend is debated. The asbestos ban enforced in Italy in 1992 gives an opportunity to measure long-term cancer risk in formerly exposed workers. METHODS: Pool of 43 previously studied Italian asbestos cohorts (asbestos cement, rolling stock, shipbuilding), with mortality follow-up updated to 2010...

INTRODUCTION: Krukenberg tumour (KT), which represents carcinoma in the ovary, is an uncommon manifestation of metastatic colorectal cancer. It is associated with poor prognosis and a high incidence of peritoneal metastatic disease.

PURPOSE OF REVIEW: Gastric outlet obstruction (GOO) can result from benign and malignant causes. Until recently, surgical gastrojejunostomy was the treatment of choice for patient with benign and malignant GOO with a good functional status. Endoscopic placement of luminal self-expandable metal stents is currently widely accepted as the first line of treatment for malignant GOO because of its effectiveness and minimally invasive nature. The main shortcoming of luminal stents is the high incidence of recurrent GOO most commonly because of tumor ingrowth/overgrowth...
