Ibero-American Consensus for the Management of Peritoneal Sarcomatosis: Updated Review and Clinical Recommendations.

Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis.

Radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal sarcomatosis: Results from a reference center and considerations based on current evidence.

Introduction: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence.

Sarcoma European and Latin American Network (SELNET) Recommendations on Prioritization in Sarcoma Care During the COVID-19 Pandemic.

Background: The COVID-19 outbreak has resulted in collision between patients infected with SARS-CoV-2 and those with cancer on different fronts. Patients with cancer have been impacted by deferral, modification, and even cessation of therapy. Adaptive measures to minimize hospital exposure, following the precautionary principle, have been proposed for cancer care during COVID-19 era.

The aim of the present study was to analyze the outcomes obtained by the application of these procedures in a single center with extensive experience treating peritoneal carcinomatosis.

Patients And Methods: A series of 218 consecutive patients diagnosed with peritoneal carcinomatosis from primary or recurrent ovarian cancer (FIGO stage IIIC-IV) and treated with CRS + HIPEC between January 1996 and June 2012 were included in this observational study.

Prediction model to discard a priori liver allografts.

Background: The use of expanded criteria for donors to expand the donor pool has increased the number of discarded liver grafts in situ. The aim of our study was to elaborate a prediction model to reduce the percentage of liver grafts discarded before the procuring team is sent out.

Methods: We analyzed the donor factors of 244 evaluated candidates for liver donation.

Peritoneal metastases of colorectal origin treated by cytoreduction and HIPEC: An overview.

Colorectal peritoneal carcinomatosis was considered a terminal condition with a merely palliative treatment that included only supportive care, palliative surgery and the best systemic chemotherapy. Since the birth of a new approach, cytoreductive surgery with peritonectomy procedures together with hyperthermic intraperitoneal chemotherapy and/or early postoperative intraperitoneal chemotherapy to treat peritoneal carcinomatosis, many research groups contributed with promising results using this procedure being up to date this strategy the only one that has shown curative benefits on colorectal peritoneal carcinomatosis achieving reported overall survival rates up to 64 mo and five-year survival rates up to 51%. The aim of this paper is to expose an updated overview of the therapeutic possibilities of these procedures in colorectal peritoneal metastases in the same way that our Unit of Oncologic Surgery has performed since 1997 with more than four hundred procedures.

Postoperative time course and utility of inflammatory markers in patients with ovarian peritoneal carcinomatosis treated with neoadjuvant chemotherapy, cytoreductive surgery, and HIPEC.

Background: Inflammatory markers may help monitor postoperative evolution of surgical patients and detect complications. However, to date, the effect that neoadjuvant chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) may have in the postoperative kinetics of these parameters remains unknown.

Methods: Between July 2011 and June 2014, all patients who underwent neoadjuvant chemotherapy, cytoreductive surgery, and HIPEC for ovarian peritoneal carcinomatosis were studied.

LC-MS/MS quantitative analysis of paclitaxel and its major metabolites in serum, plasma and tissue from women with ovarian cancer after intraperitoneal chemotherapy.

A method for determination of the antineoplastic drug paclitaxel and its main metabolites (viz. 6α-hydroxypaclitaxel and p-3'-hydroxypaclitaxel) at the sub-ng/ml level is here presented. Sample preparation consisted of a liquid-liquid extraction step for cleanup and preconcentration of the target analytes prior to chromatographic analysis by tandem mass spectrometry detection (LC-ESI-MS/MS).

Outcome of patients with aggressive pseudomyxoma peritonei treated by cytoreductive surgery and intraperitoneal chemotherapy.

Background: Pseudomyxoma peritonei (PMP) is a rare disease with an incidence rate of approximately 1 per million a year. During the past few years, there has been a survival benefit for these patients treated by complete cytoreduction and perioperative chemotherapy. Better survival rates were found in the adenomucinosis group than the carcinomatosis group.

Neoadjuvant intraperitoneal chemotherapy with paclitaxel for the radical surgical treatment of peritoneal carcinomatosis in ovarian cancer: a prospective pilot study.

Purpose: The admitted benefits of intraperitoneal chemotherapy during postoperative administration for the treatment of peritoneal carcinomatosis from ovarian origin are limited by their associated morbidity and restricted diffusion by the presence of multiple intra-abdominal adherences. The purpose of the study was to evaluate the security, effectiveness, and cytoreduction optimization of intraperitoneal paclitaxel administration previously to radical surgery/peritonectomy/HIPEC (hyperthermic intraoperative intraperitoneal chemotherapy) either in monotherapy or combined with intravenous carboplatin.

Methods: Prospective pilot study of 10 patients with ovarian peritoneal carcinomatosis in stage IIIc-FIGO without previous treatment.

Pseudomyxoma peritonei treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: results from a single centre.

Background: Pseudomyxoma peritonei (PMP) is a rare, slowly progressive disease whose prognosis depends primarily on the completeness of cytoreduction. The value of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) and of additional factors predicting long-term outcome and disease-free survival (DFS) remains poorly understood. This study aims to analyse survival rates and prognostic factors in patients undergoing maximal cytoreduction and HIPEC.

Consolidation of enteric drainage for exocrine secretions in simultaneous pancreas-kidney transplant.

Introduction: Management of the exocrine drainage of the pancreatic graft in simultaneous pancreas kidney (SPK) transplantation has been a matter of debate for years. There is currently a trend toward a more physiological enteric drainage (ED). This study compared short- and long-term complications and graft survival in patients with enteric versus bladder exocrine secretion drainage.

Objective: To analyze the different factors predictive of survival associated with optimal R0-cytoreduction in c-kit-positive gastrointestinal stromal tumors.

Methods: Thirty-five patients were operated on in our Oncological Surgery Department from January 2002 to February 2007 because of CD117/c-kit-positive gastrointestinal stromal tumors, and an optimal surgical cytoreduction was obtained without macroscopical residual disease. Demographic, anatomical, clinical, pathological, and immunohistochemical variables were analyzed from a specific database.

Treatment of peritoneal carcinomatosis from ovarian cancer. Present, future directions and proposals.

Peritoneal carcinomatosis, considered years ago as a final stage of unresectable cancer, can now be managed with curative intention by means of a radical cytoreductive surgical procedure with associated peritonectomy and intraperitoneal chemotherapy, as described by Sugarbaker. Malignant neoplasms such as mesothelioma and pseudomyxoma peritonei, ovarian and colon cancer nowadays are experiencing some new therapeutical approaches. Higher survival rates can be reached in ovarian cancer, which is commonly diagnosed in the presence of peritoneal carcinomatosis, using an optimal cytoreductive radical surgery with intraperitoneal chemotherapy.

Radical surgery-peritonectomy and intraoperative intraperitoneal chemotherapy for the treatment of peritoneal carcinomatosis in recurrent or primary ovarian cancer.

Background And Objectives: Advanced ovarian cancer typically spreads in a diffuse intra-abdominal fashion. This characteristic suggests that combined radical surgery and intraperitoneal chemotherapy may be a useful treatment procedure. The purpose of this study was to review patients submitted to surgical debulking and hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) and to evaluate the potential prognostic survival factors for advanced epithelial ovarian cancer in our center.

Melatonin reduces apoptosis and necrosis induced by ischemia/reperfusion injury of the pancreas.

The pancreas is highly susceptible to the oxidative stress induced by ischemia/reperfusion (IR) injury leading to the generation of acute pancreatitis. Melatonin has been shown to be useful in the prevention of the damage by ischemia-reperfusion in liver, brain, myocardium, gut and kidney. The aim of the study was to evaluate the cytoprotective properties of melatonin against injury induced by IR in pancreas.
