INTRODUCTION: The treatment of advanced primary or recurrent ephitelial ovarian cancer still remains an open and a critical question. The addition of HIPEC to cytoreductive surgery has showed improving overall survival rates. The aim of our study is to describe the progress in its management in our Unit and what we have learned after more than 350 HIPEC procedures. METHODS: From 1997 to 2016 we conducted a retrospective analysis from a prospective database. We described and analyzed 4 cut-points, 1997-2004, 2009, 2012 and 2016...

BACKGROUND: Cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS-HIPEC) prolongs survival in patients with metastatic peritoneal disease. We look at the incidence of acute kidney injury (AKI) in patients who have received cisplatin during CRS-HIPEC in the treatment of peritoneal carcinomatosis from an ovarian primary, and identify possible peri-operative risk factors. METHODS: Between 2005 and 2013, we performed CRS-HIPEC on 47 patients with ovarian primaries and peritoneal metastasis...

Ovarian cancer, a leading cause of death in women, typically spreads locally and rarely metastasizes to the brain or seeds the leptomeninges. We present a case of a 62-year-old woman with a history of treated ovarian cell carcinoma who developed bilateral sensorineural deafness and right-sided facial weakness and on imaging was found to have bilateral internal auditory canal (IAC) masses and leptomeningeal carcinomatosis, pathologically proven by cerebrospinal fluid cytology. We discuss her magnetic resonance imaging and positron emission tomography-computed tomography findings and review the imaging characteristics of IAC metastases...

A 3-year-old Weimaraner dog was presented with bilateral papillary ovarian carcinoma and abdominal carcinomatosis. Treatment included ovariectomy, intraperitoneal cisplatin, and systemic carboplatin. Pleural carcinomatosis 473 days following surgery was treated with intrapleural cisplatin through indwelling pleural access ports. Euthanasia occurred 1154 days following surgery due to malignant pleural effusion without peritoneal effusion.

OBJECTIVES: Ovarian cancer leads to abdominal carcinomatosis and late stage (III/IV) diagnosis in 75% of patients. Three randomized phase III trials have demonstrated that intraperitoneal (IP) chemotherapy improves outcomes in epithelial ovarian cancer. While IP treatment is validated by clinical trials, there is a poor understanding of the mechanism(s) leading to the survival advantage other than the increased concentration of cytotoxic drugs within the tumor microenvironment. A better understanding of this process through analysis of dynamic biomarkers should promote novel approaches that may enhance tumor clearance...

Waldenström's macroglobulinemia is a rare hematology malignancy which often presents with "B symptoms," anemia, and thrombocytopenia. A 46-year-old woman presented with 2 months of abdominal distension accompanied by an unintentional 20-lb weight loss. Her abdominal CT scan demonstrated diffuse carcinomatosis with bilateral ovarian lesions and screening labs revealed a markedly elevated CA-125, suggesting a diagnosis of ovarian cancer. Upon admission for workup, patient was found to have a significant protein gap, later attributed to a markedly elevated IgM...

OBJECTIVE: Epithelial ovarian cancer (EOC) management remains association of debulking surgery in combination with platinum-based chemotherapy. Sixty percent of women with EOC considered in remission will develop recurrent disease. An option to improve the completion of cytoreductive surgery may be the use of photodynamic therapy to induce necrosis of peritoneal metastases. A limit of this technique was the toxicity induced by the lack of specificity of old-generation photosensitizer (PS) for tumor tissue if the light could not be specifically applied...

Effective therapeutics for ovarian cancer continue to be urgently needed, particularly for chemotherapy-resistant cases. Here we present both a 3D-Matrigel culture-based expansion of our directed evolution method for generation of oncolytic virotherapies and two promising ovarian-cancer targeted oncolytic viruses, OvAd1 and OvAd2. OvAd1 was developed using Matrigel cell cultures, whereas OvAd2 was developed in parallel using traditional monolayer tissue culture methods. Both viruses are potent against a panel of platinum-resistant ovarian cancer cell lines and are attenuated on normal cells in vitro, resulting in therapeutic windows of ∼200-fold...

Given the unique intra-peritoneal anatomic location of the adnexa, tubo-ovarian diseases can commonly spread into the peritoneal cavity. Peritoneal seeding may occur in a spectrum of adnexal conditions including infectious diseases, endometriosis, and benign or malignant primary or secondary ovarian tumors. CT is usually the imaging modality on which the concomitant involvement of the peritoneum and the ovary is depicted. The first diagnosis to be considered by the radiologist is generally peritoneal carcinomatosis from ovarian cancer but other conditions cited above have also to be borne in mind and may be suggested on the basis of careful assessment of CT findings or on further MR findings...

Peritoneal dissemination is the primary metastatic route of ovarian cancer (OvCa), and is often accompanied by the accumulation of ascitic fluid. The peritoneal cavity is lined by mesothelial cells (MCs), which can be converted into carcinoma-associated fibroblasts (CAFs) through mesothelial-to-mesenchymal transition (MMT). Here, we demonstrate that MCs isolated from ascitic fluid (AFMCs) of OvCa patients with peritoneal implants also undergo MMT and promote subcutaneous tumour growth in mice. RNA sequencing of AFMCs revealed that MMT-related pathways - including transforming growth factor (TGF)-β signalling - are differentially regulated, and a gene signature was verified in peritoneal implants from OvCa patients...

The treatment of peritoneal carcinomatosis (PC) of colorectal origin with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has a 5-year recurrence-free or cure rate of at least 16%, so it is no longer labeled as a fatal disease, and offers prolonged survival for patients with a low peritoneal carcinomatosis index. Metachronous PC of colorectal origin is so predictable that there is a model which has been used to successfully determine the individual risk of each patient. Patients at risk are clearly identified; those with the highest risk have small peritoneal nodules present in the first surgery (70% probability of developing PC), ovarian metastases (60%), perforated tumor onset or intraoperative tumor rupture (50%)...

We report a case of a 72-year-old woman who was initially diagnosed with ovarian cancer with peritoneal carcinomatosis. Systemic chemotherapy consisting of paclitaxel and carboplatin(TC)was administered. Although a partial response(PR)was achieved after the 4 courses of TC, this regimen was discontinued due to severe adverse events. Ten months after discontinuation of TC, because abdominal CT and colonoscopy showed an intra-tumoral abscess caused by invasion of the tumor to the sigmoid colon, abdominal total hysterectomy, bilateral salpingo-oophorectomy, and a Hartmann's operation were performed to control the disease symptoms...

A current challenge in the treatment of peritoneal carcinomatosis is the inability to detect, visualize, and resect small or microscopic tumors of pancreatic, ovarian, or mesothelial origin. In these diseases, the completeness of primary tumor resection is directly correlated with patient survival, and hence, identifying small sub-millimeter tumors (i.e., disseminated disease) is critical. Thus, new imaging techniques and probes are needed to improve cytoreductive surgery and patient outcomes. Highly fluorescent rhodamine-labeled expansile nanoparticles (HFR-eNPs) are described for use as a visual aid during cytoreductive surgery of pancreatic carcinomatosis...
