Active clinical trials for "Retroperitoneal Neoplasms"

This phase Ib trials studies the side effects and best dose of eribulin mesylate when given together with radiation therapy in treating patients with retroperitoneal liposarcoma that can be removed by surgery. Drugs used in chemotherapy, such as eribulin mesylate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells.

This phase Ib trial studies the side effects and best dose of nivolumab with or without ipilimumab in treating patients with female reproductive cancer that has come back (recurrent) or is high grade and has spread extensively throughout the peritoneal cavity (metastatic). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

The goal of this prospective phase 2 study is to assess the efficacy and safety of intestinal or multivisceral transplantation for participants with PMP not amenable to other curative-intent treatments. Participants will undergo intestinal/multivisceral transplantation. Participants will be followed for 12 months to assess efficacy and safety.

There has been no successful treatment of diffuse peritoneal metastasis or carcinomatosis, in childhood tumors. Once this advanced stage of disease is evident, survival is measured in weeks. The selective lethal effect of supranormal temperatures on neoplastic cells and the additive or synergistic effect of combining chemotherapy has been well established in adult clinical trials using continuous hyperthermic peritoneal perfusion (CHPP) for advanced peritoneal adenocarcinoma of gastrointestinal origin, ovarian carcinoma and mesothelioma. This phase I study will evaluate the safety of continuous hyperthermic peritoneal perfusion with escalating doses of intraperitoneal cisplatin in the treatment of children with refractory tumors limited to the abdominal cavity. If tumors are outside the abdominal cavity, the tumors must be able to be controlled. Since CHPP has potential to improve outcome of children with peritoneal and retroperitoneal metastases, this study will evaluate the safety of elevated temperature (40oC) with intraperitoneal cisplatin chemotherapy. Primary Objectives: To determine the MTD and dose-limiting toxicity of intraperitoneal cisplatin given in combination with CHPP as a 90 minute perfusion in children with advanced peritoneal and retroperitoneal solid tumors To determine the safe and tolerable dose of CHPP with cisplatin to be used in Phase II trials To determine the pharmacokinetics of intraperitoneal cisplatin platinum given with CHPP as a 90 minute abdominal perfusion (Optional)

Investigators will use Axumin PET/CT to help with the imaging modalities to determine the presence of occult retroperitoneal disease.

Background: Retroperitoneal tumors are typically large and inhomogeneous, with a variable amount of necrosis within the tumor mass which decreases the diagnostic yield of biopsy (false negative or inadequate). Rationale: Real-time contrast enhancement can highlight the viable tumoral tissue and avoid the necrotic area. Aims: To compare contrast-enhanced ultrasound (CEUS) guidance and conventional (B-mode) ultrasound (US) guidance in terms of diagnostic yield, need for repeat biopsy, and rate of adverse events. Methods: A consecutive series of patients with previously documented retroperitoneal tumors and indications for percutaneous biopsy were randomly assigned to benefit from the standard of practice B-mode US-guided biopsy or CEUS-guided biopsy. The diagnostic accuracy, need for repeat biopsy, and adverse events were noted.

No prospective data exist about long term morbidity and quality of life after multivisceral surgical resection for retroperitoneal soft tissue sarcoma (RSTS). In order to assess the safety of this surgical approach and the effect on the Quality of Life over the long period we propose a prospective observational study. The hypothesis is that the surgical treatment has no significant impact in determining a lower Quality of Life in the long term. Objectives Primary objective Estimate the difference between baseline and 4 and 12 months scores of the "global health status / QoL" scale in patients primarily treated for localized RSTS, as determined in QLQ-C30 version 3.0. Secondary objectives Evaluate the long term morbidity of aggressive surgical approach to RSTS in terms of renal failure. Evaluate the difference between baseline and 4 and 12 months scores of DN4 / LEFS / BPI questionnaires. Evaluate the difference between baseline and 4 and 12 months scores of the following scales from QLC-C30: PF2, RF2, EF, CF, SF, FA, FI. Evaluate the difference between baseline and 4 and 12 months scores of the following scales and single items from QLC-C29: Blood and mucus in stool, Stool frequency, Sexual interest, Impotence, Dyspareunia. To correlate the surgical resection pattern (number and type of organs resected) and the tumor features (size, grading and histological subtype) with the long-term morbidity and quality of life. Eligibility Inclusion criteria Adult patients (age > 18 years) with primary localized RSTS surgically treated at our institution Written, voluntary, informed consent Exclusion criteria - Recurrent disease
