Peritoneal carcinomatosis (PC) from colorectal cancer (CRC) is a disease with a poor prognosis, often thought to be a terminal illness with no hope except for palliative treatment. New therapeutic modalities combining cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown favorable outcomes and may provide a significant survival benefit in a selected group of patients. The main rational for CRS is to remove all visible tumor burden to allow for the chemotherapeutic agent (HIPEC) to eradicate any microscopic residual disease...

BACKGROUND AND AIMS: During endoscopic full-thickness resection (EFTR) for cancers, whether exposure of the lumen to the abdominal cavity during the procedure is acceptable is controversial because of the potential risk of tumor cell seeding. To assess the possibility of transplantation due to contact with tumor cells during the procedure, we prospectively investigated the ability of cancer cells to be detached by touching the tumor surface. METHODS: In 48 patients with a single early gastric cancer resected by endoscopic submucosal dissection, stamp cytology was performed by touching the surface of the specimens to glass slides...

Transabdominal ultrasound not always allows to determine the nature of ascites based solely on its characteristics. AIM: The aim of the study was to present difficulties in determining the nature of ascites using transabdominal ultrasonography solely based on extra-organ lesions as well as, after the inclusion of the overall abdominal assessment and the clinical picture. MATERIALS AND METHODS: A total of 18 patients with non-neoplastic ascites and 62 patients with neoplastic ascites whose final diagnosis was based on cytological and histopathological findings were evaluated between 2005 and 2015...

The vermiform appendix is the primary site of several distinctive benign and malignant neoplasms. Some can produce the clinical syndrome of pseudomyxoma peritonei (PMP). A consensus on their terminology was reached by an international panel of pathologists and clinicians working under the auspices of the Peritoneal Surface Oncology Group International (PSOGI) and this review discusses the application of the PSOGI classification to routine reporting. We discuss diagnosis and differential diagnosis together with implications for patient management, covering low-grade appendiceal mucinous neoplasms, high-grade appendiceal mucinous neoplasms, serrated polyps, adenomas, and adenocarcinomas...

PURPOSE: To identify the role of systemic chemotherapy in the management of appendiceal malignancies. METHODS: Over a 10-year period (2005 -2014), 52 patients with appendiceal neoplasms were treated at our Peritoneal Surface Malignancy Unit [14 (26.9%) disseminated peritoneal adenomucinosis (DPAM), 30 (57.7%) peritoneal mucinous carcinomatosis of appendiceal origin (PMCA) and 8 (15.4%) PMCA-I]. All patients (100%) underwent cytoreductive surgery (CRS) & hyperthermic intraperitoneal chemotherapy (HIPEC), while 20 (38...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

OBJECTIVES: This study investigated the correlation between the peritoneal carcinomatosis index (PCI) and patient outcome depending on the tumour type. BACKGROUND: Peritoneal surface malignancy (PSM) treatment depends on tumour type. Mucinous PSM (m-PSM) is associated with a better prognosis than non-mucinous PSM (nm-PSM). The PCI's predictive ability has not yet been evaluated. METHODS: We analysed 123 patients with PSM treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) between 2008 and 2015...

BACKGROUND AND OBJECTIVES: Repeat cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for recurrence of peritoneal surface malignancies is safe and effective. Patient selection and factors associated with a favorable outcome are still evolving. METHODS: A prospectively maintained institutional database consisting of 1314 CRS/HIPEC procedures performed between February 1993 and December 2015 was reviewed. Clinicopathologic data from 103 patients and 112 (8...

Gastrointestinal and gynecological malignancies disseminate in the peritoneal cavity - a condition known as peritoneal carcinomatosis (PC). Intraperitoneal (IP) administration can be used to improve therapeutic index of anticancer drugs used for PC treatment. Activity of IP anticancer drugs can be further potentiated by encapsulation in nanocarriers and/or affinity targeting with tumor-specific affinity ligands, such as tumor homing peptides. Here we evaluated a novel tumor penetrating peptide, linTT1 (AKRGARSTA), as a PC targeting ligand for nanoparticles...

Purpose/Aim: Colorectal malignity is one of the most common forms of cancer. The finding of free intraperitoneal colorectal cancer cells during surgery has been shown to be associated with poor outcome. The aim of this study was to develop an experimental model designed to investigate adhesion of colorectal cancer cells to the peritoneal surface. MATERIALS AND METHODS: Two human experimental models were developed, the first using cultured mesothelial cells and the second consisting of an ex vivo model of peritoneal tissue...

AIM: The treatment of peritoneal surface malignancies ranges from palliative care to full cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy, HIPEC. Ongoing monitoring of patient recruitment and volume is usually carried out through dedicated registries. With multiple registries available worldwide, we sought to investigate the nature, extent and value of existing worldwide CRS and HIPEC registries. METHODS: A questionnaire was sent out to all known major treatment centres...

BACKGROUND: During the Fifth International Workshop on Peritoneal Surface Malignancy in Milan in 2008, a consensus was reached that contrast-enhanced CT (ceCT) was the principal imaging modality for patients being evaluated for treatment of peritoneal metastases. This fact being accepted, the radiologic criteria for that may exclude patients from a high value cytoreductive surgery (CRS) plus hyperthermic perioperative chemotherapy (HIPEC) have not been reliably determined. METHODS: From a consensus of surgeons and radiologists, radiologic images were selected and their determinant radiologic characteristics described...

Pseudomyxoma peritonei (PMP) is an uncommon disease characterized by mucinous ascites, classically originating from a ruptured low grade mucinous neoplasm of the appendix. The natural history of PMP revolves around the "redistribution phenomenon", whereby mucinous tumour cells accumulate at specific sites with relative sparing of the motile small bowel and to a lesser extent other parts of the gastrointestinal tract. Peritoneal tumour accumulates due to gravity and at the sites of peritoneal fluid absorption, namely, the greater and lesser omentum and the under-surface of the diaphragm, particularly on the right...

Peritoneal surface malignancy (PSM) is a common manifestation of digestive and gynaecologic malignancies alike. At present, patients with isolated PSM are treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic peroperative intraperitoneal chemotherapy (HIPEC). The combination of CRS and intraperitoneal (IP) chemotherapy should now be considered standard of care for PSM from appendiceal epithelial cancers, colorectal cancer and peritoneal mesothelioma. Although there is a near universal standardisation regarding the CRS, we are still lacking a much-needed standardisation amongst the various IP chemotherapy treatment modalities used today in clinical practice...

Peritoneal Carcinomatosis (PC) is a late stage manifestation of several gastrointestinal malignancies including appendiceal, colorectal, and gastric cancer. In PC, tumors metastasize to and deposit on the peritoneal surface and often leave patients with only palliative treatment options. For colorectal PC, median survival is approximately five months, and palliative systemic therapy is able to extend this to approximately 12 months. However, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) with a curative intent is possible in some patients with limited tumor burden...

Epithelial ovarian cancer (EOC) is one of the deadly gynecological malignancies. The function of protein kinase CK2α (CK2α) in EOC is still unknown. Our study aimed to investigate the relationship between the protein expression of CK2α and the tumor progression, the prognosis of human EOC. In this study, we analyzed the expression levels of CK2α through Western blot, using EOC cell lines like A2780, HO8910, COV644, OVCAR3, SKOV3, and the primary normal ovarian surface epithelial (NOSE) cells. Furthermore, OVCAR3 and SKOV3 EOC cells were employed as a cellular model to study the role of CK2α on cell growth, migration, invasion, apoptosis, and cell cycle distribution...

BACKGROUND: Only approximately one in ten pancreas cancer patients is a candidate for potentially curative resection of this disease. Even this small fraction of patients has a poor prognosis following pancreatico-duodenectomy. The disease has an anatomic location that makes it difficult for the surgeon to maintain adequate margins of resection and prevent tumor spillage at the time of resection. Also, the disease is biologically aggressive and even with a complete visible resection of the disease, micrometastases are likely to remain behind...
