OBJECTIVE: Circulating tumor cells (CTCs) may represent a chronic stimulus for the immune system. In the present study we investigated the potential association of CTCs, the immune activation marker neopterin, and the ratio of kynurenine to tryptophan (Kyn/Trp) as a measure for tryptophan breakdown. METHODS: Neopterin, tryptophan and kynurenine levels were measured in plasma samples from patients with benign gynecological diseases (n=65) and with primary advanced epithelial ovarian cancer (EOC) at diagnosis (n=216) and six months after adjuvant platinum-based chemotherapy (n=45) by an enzyme-linked immunosorbent assay and high performance liquid chromatography...

BACKGROUND: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new drug delivery method offered in selected patients suffering from non-resectable peritoneal carcinomatosis (PC). As reported experience is still limited, we conducted a survey among active PIPAC centers aiming to report their technical approach and clinical findings. METHODS: An online survey was sent to active PIPAC centers worldwide. The questionnaire consisted of 34 closed questions and was conducted over a period of 3 months beginning in March 2017...

In order to reach cytoreduction in advanced ovarian cancer, peritonectomy and diaphragmatic stripping are procedures required to remove the disease in the upper abdomen. Diaphragm involvement is estimated in up to 40% of cases. Nevertheless, in some of these patients, the tumour volume may constitute a limitation of the technique due to the association with abdominal wall involvement, bulky tumour at the Morrison's pouch or liver infiltration. Extensive upper abdominal procedures should represent a basic resource for the gynaecologic oncologist in order to reach an optimal cytoreduction...

BACKGROUND: The peritoneal carcinomatosis index (PCI) can be used to quantify the tumor burden in patients with advanced ovarian cancer. The aim of the present study was to establish a predictive model for suboptimal cytoreductive surgery (SCS) (residual tumor of > 1 cm) using preoperative and intraoperative determination of the PCI. METHODS: In total, 110 consecutive patients treated for advanced ovarian cancer during a 4-year period in our institution were assessed...

Small intestinal endocrine tumours (SI-NETs) are generally considered resistant to systemic treatment. To date, predictive markers for drug activity are lacking. Tumour samples from 27 patients with SI-NETs were analyzed ex vivo for sensitivity to a panel of cytotoxic drugs and targeted agents using a short-term total cell kill assay. Samples of renal cancer, colorectal cancer (CRC), ovarian cancer, and chronic lymphocytic leukemia (CLL) were included for comparison. For the SI-NET subset, drug sensitivity was analyzed in relation to clinico-pathological variables and pre-treatment biomarkers...

BACKGROUND: Ovarian, tubal, and peritoneal carcinomas primarily affect the peritoneal cavity, and they are typically diagnosed at an advanced tumor stage (Foley, Rauh-Hain, del Carmen in Oncology (Williston Park) 27:288-294, 2013). In the course of primary surgery, postoperative tumor residuals are, apart from the tumor stage, the strongest independent factors of prognosis (du Bois, Reuss, Pujade-Lauraine, Harter, Ray-Coquard, Pfisterer in Cancer 115:1234-1244, 2009). Due to improved surgical techniques, including the use of multi-visceral procedures, macroscopic tumor clearance can be achieved in oncological centers, in most cases (Harter, Muallem, Buhrmann et al in Gynecol Oncol 121:615-619, 2011)...

BACKGROUND: Risk-reducing salpingo-oophorectomy (RRSO) is recommended for BRCA1/2 mutation carriers because of their increased risk of ovarian carcinoma. Despite RRSO, metachronous peritoneal carcinomatosis occasionally is diagnosed. METHODS: The literature was searched for BRCA1/2 mutation carriers with peritoneal carcinomatosis after risk-reducing surgery. The authors were asked for additional data. Clinical and histopathological data were descriptively analyzed...

Surgery is often the first treatment option for patients with cancer. Patient survival essentially depends on the completeness of tumor resection. This is a major challenge, particularly in cases of peritoneal carcinomatosis, where tumors are widely disseminated in the large peritoneal cavity. Any development to help surgeons visualize these residual cells would improve the completeness of the surgery. For non-disseminated tumors, imaging could be used to ensure that the tumor margins and the draining lymph nodes are free of tumor deposits...

The cytoreductive surgery (CRS) and HIPEC has showed promising results for the survival in patients with recurrent ovarian carcinomatosis, however, some of them will recur within the first year. The aim of this study is focused on identifying the risk factors to develop the recurrence within the first year after an optimal CRS-HIPEC in patients with recurrent ovarian carcinomatosis. METHODS: A total of 100 patients with peritoneal carcinomatosis from recurrent ovarian cancer treated by CRS+HIPEC were selected for analysis...

Gastric cancer remains one of the most aggressive malignancies, being associated with very poor therapeutic outcomes, especially in the advanced disease patients. Due to this evidence, finding a better treatment, a better control and higher survival rates is the current scientific focus of the medical community. Once the benefits of cytoreductive surgery in association with intraperitoneal hyperthermy (HIPEC) have been widely demonstrated in patients presenting peritoneal carcinomatosis from colorectal or ovarian origin,attention was focused on the possible benefit of this method in patients diagnosed with peritoneal carcinomatosis with gastric origin...

Mechanism-inspired drug repurposing that augments standard treatments offers a cost-effective and rapid route toward addressing the burgeoning problem of plateauing of effective therapeutics for drug-resistant micrometastases. We show that the antibiotic minocycline, by its ability to minimize DNA repair via reduced expression of tyrosyl-DNA phosphodiesterase-1 (Tdp1), removes a key process attenuating the efficacy of irinotecan, a frequently used chemotherapeutic against metastatic disease. Moreover, minocycline and irinotecan cooperatively mitigate each other's undesired cytokine inductions of VEGF and IL8, respectively, thereby reinforcing the benefits of each modality...

Epithelial ovarian cancer (EOC) metastasizes intra-abdominally with often numerous, superficial, small-sized lesions. This so-called peritoneal carcinomatosis is difficult to treat, and peritoneal recurrences are frequently observed, leading to a poor prognosis. Underlying mechanisms of interactions between EOC and peritoneal cells are incompletely understood. This review summarizes and discusses the development of peritoneal carcinomatosis from a cell-biological perspective, focusing on characteristics of EOC and peritoneal cells...

Background: Gastric cancer patient with ovarian metastasis is common in clinical practice, but it is still uncertain whether surgical resection of ovarian metastasis could improve the outcome. This study aimed to explore the survival benefit of metastasectomy plus chemotherapy over chemotherapy alone in the treatment of Krukenberg tumors arising from gastric cancer and to identify prognostic factors. Results: A total of 152 patients were identified, including 93 patients with synchronous ovarian metastasis and 59 patients with metachronous ovarian metastasis...

Image-guided surgery is a relevant way to reduce surgical morbidity and maximize cytoreductive surgery approach especially in ovarian cancer. Sentinel lymph node detection is a promising approach to avoid radical lymph node dissection and is slightly becoming standard in daily practice in endometrial and cervical cancer surgery even if it needs to be evaluated more precisely. Regarding carcinomatosis of ovarian origin, detection and treatment of microscopic disease could be appropriate to avoid local recurrences...

OBJECTIVE: Postoperative residual tumor is the major prognostic factor in ovarian cancer. The feasibility of complete cytoreductive surgery is assessed by laparoscopy. Our goal was to develop a predictive score prior to laparoscopy to evaluate the feasibility of complete cytoreductive surgery in patients with epithelial ovarian cancer. METHODS: We developed a score to predict incomplete cytoreductive surgery by performing multiple logistic regressions after bootstrap procedures on data from a retrospective cohort of 247 patients with advanced ovarian cancer...

AIM OF THE STUDY: We set out to develop and evaluate the morbidity of a non-invasive hyperthermic intraperitoneal chemotherapy (HIPEC) procedure in mice. HIPEC has been shown to improve overall survival in treating ovarian cancer with peritoneal carcinomatosis. However, related complications, toxicity and the lack of randomized trials limits its widespread use. To improve the surgical technique, there is a need for animal models that allow teams to work on large groups without burdensome logistics...

Recently, we reported 2 mixed endometrioid endometrial carcinomas with a low-grade serous-like component which doesn't fit into any of the 4 molecular groups described by The Cancer Genome Atlas (TCGA). In order to understand the nature of these tumors, we have done an immunohistochemical and molecular genetic study of these two cases and added a third case. Immunoreactivity for p53, ER, Ki67, WT1, MLH1, PMS2, MSH2, and MSH6 were assessed. Targeted next-generation sequencing for somatic mutations, including genes commonly implicated in carcinogenesis including TP53, KRAS, and PIK3CA, and Sanger sequencing for PTEN and POLE were also performed...
