Filter by:The protocol intends to explore the biology which may underlie recurrences of retroperitoneal liposarcoma. Surgery remains the only curative intent intervention for this disease. Often, tumors recur in locations within the retroperitoneum remote from the original primary tumor. This study hypothesizes that normal appearing retroperitoneal fat actually harbors underlying genetic changes which predispose to development of future liposarcoma. To accomplish this goal, retroperitoneal fat is sampled from quadrants within and remote from the primary tumor and is subsequently subjected to genetic analyses looking for such predisposing factors.
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.
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.
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.
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
Investigators will use Axumin PET/CT to help with the imaging modalities to determine the presence of occult retroperitoneal disease.
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.
Phase I/II multicenter and prospective trial of nilotinib and adriamycin as neoadjuvant treatment in liposarcomas and leiomyosarcomas of retroperitoneum. The main objective of this study is to improve relapse-free survival (RFS)and overall survival (OS) decreasing from 50% to 30% the relapse percentage at 5 years in patients with resected sarcoma of retroperitoneum. Secondary objectives include the analysis of antitumoral activity through response rate (RECIST and tissular changes), the assessment of positive correlation between biomarkers and clinical results, the study of long term overall survival, and the analysis of the safety profile of the nilotinib-adriamycin combination. The trial hypothesis is that the nilotinib-adriamycin combination is synergistic and therefore better response results are expected (from 20% as P0 to 40% as P1). The study seeks to find a positive correlation between biomarkers and clinical results in retroperitoneal liposarcoma and leiomyosarcoma treated with the mentioned combination. The study involves the participation of 20 hospitals of the Spanish Sarcoma Group (GEIS). The treatment consists of 4 neoadjuvant cycles of nilotinib-adriamycin on patients with resectable retroperitoneal sarcoma. The research comprises a robust translational study as well as histological and radiological reviews.
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: 1. 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 2. To determine the safe and tolerable dose of CHPP with cisplatin to be used in Phase II trials 3. To determine the pharmacokinetics of intraperitoneal cisplatin platinum given with CHPP as a 90 minute abdominal perfusion (Optional)
