Background: An increasing promising evidence and increasing long-term oncologic outcomes support the use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as locoregional treatment for peritoneal carcinosis (PC) especially from ovarian and gastrointestinal tumors, but also for others cancers. Methods: A prospective monocentric study was performed in Papa Giovanni XXIII Hospital, Bergamo (Italy). Patients and tumor characteristics were analyzed...

OBJECTIVE: We performed a phase I, single-arm, non-randomized, open-label, dose-escalation trial to determine the dose-limiting toxicity of intraperitoneal cisplatin and doxorubicin applied as pressurized intraperitoneal aerosol chemotherapy (PIPAC) in women with recurrent ovarian cancer. METHODS: We used a standard 3 + 3 dose-escalation design with doxorubicin 1.5 mg/m2 , cisplatin 7.5 mg/m2 q 4 to 6 weeks for 3 cycles and subsequent dose escalation steps (20% increment per step) in patients with recurrent ovarian cancer and peritoneal carcinomatosis...

Failure of currently used cytotoxic chemotherapy is one of the main reasons behind high mortality from metastatic high grade serous ovarian carcinoma. We found that high expression of a receptor for fractalkine (CX3 CR1) significantly correlated with shorter survival of patients with serous ovarian carcinoma treated with cytotoxic DNA damage chemotherapies, and reduction of CX3 CR1 expression resulted in sensitization to several DNA damaging modalities, including x-ray radiation and cisplatin. Here, we show that CX3 CR1 plays a role in double-strand DNA break response and repair by regulating expression of RAD50 by a MYC-dependent mechanism...

BACKGROUND: Treatment of peritoneal metastases has gained interest among oncologic communities around the world. Cytoreductive surgery (CRS) and hyperthermic intraoperative chemotherapy (HIPEC) have come to be the treatment of choice for selected patients with peritoneal carcinomatosis (PC) in recent years. Prior to HIPEC, patients were treated with palliative support and only guaranteed a few months to live. We reviewed our first 30 patients who underwent CRS and HIPEC. The aim of the study was assessment of the patients' survival, morbidity, and mortality rate and identifying prognostic factors of patients treated with CRS and HIPEC...

BACKGROUND: The cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has become the standard treatment in patients with carcinomatosis peritoneal from different origins. The use of a minimally invasive approach for this high complex procedure might be an alternative that provides them less morbidity and faster recovery with similar oncologic outcomes. METHODS: We describe the initial experience of CRS and HIPEC done via the laparoscopic route in patients with minimal peritoneal metastases in our Unit from March 2016 to January 2018...

We have developed the 16F12 mouse monoclonal antibody (mAb) that targets the MISRII receptor expressed by ovarian tumors. Here, we assessed in preclinical models the possibility to use radiolabeled 16F12 in a theranostic approach for small-volume ovarian peritoneal carcinomatosis, for instance after cytoreductive surgery. Methods: DOTA-, DTPA- or DFO-conjugated 16F12 mAb was radiolabeled with beta (177 Lu) or alpha (213 Bi) particle emitters for therapeutic use, and with 89 Zr for positron emission tomography (PET) imaging...

Understanding the biology and progression mechanisms of peritoneal metastases in ovarian epithelial cancers (EOC) is important because peritoneal carcinomatosis is present or will occur during surveillance of a majority of patients. Despite the clinical remission achieved after complete macroscopic cytoreductive surgery and platinum-based chemotherapy, 60% of patients will develop peritoneal recurrence. This suggests that microscopic lesions, which are not eradicated by surgery may be present and may participate in the mechanisms leading to peritoneal recurrence...

Interferon regulatory factor-4 binding protein (IBP) is as a type of ρ GTPase suggested to serve an important role in tumor occurrence and development through the effects of cytoskeletal remodeling, and cell conduction mechanism. IBP is widely expressed in the immune system and expressed in several types of tumors. However, its expression and prognostic value in epithelial ovarian carcinoma (EOC) remain unclear. The present study aimed to investigate the expression of IBP in EOC, and its effect on clinicopathological variables and prognosis...

Pseudomyxoma peritonei (PMP) and extragastrointestinal stromal tumors (E-GISTs) are both rare entities. Most of the time, PMP is associated with an appendiceal tumor. An ovarian mucinous tumor can mimic appendiceal metastases. E-GIST is a mesenchymal tumor that can arise from the omentum, retroperitoneum, mesentery, or pleura. We present a case of an 87-year-old woman with mucinous carcinomatosis and acute intestinal occlusion submitted to an emergency laparotomy. She has found to have a borderline mucinous tumor of the ovary from the intestinal type with several lesions of pseudomyxoma peritonei and an E-GIST from the epiploons retrocavity (intermediated risk)...

BACKGROUND: Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) represents a treatment option for peritoneal surface malignancies. Even if it has been reported that this new approach improved survival of selected patients, it's still associated with high morbidity and mortality rates. METHODS: From October 1995 to December 2017, over 450 patients patients affected by peritoneal carcinomatosis (PC) underwent in our Institute to CRS associated with HIPEC...

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 neuroendocrine tumors (SI-NETs) are generally considered resistant to systemic treatment. To date, predictive markers for drug activity are lacking. Tumor 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 clinicopathological 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)...
