Filter by:Soft tissue sarcomas are rare malignant tumors. Liposarcoma constitute the most frequent histological subtype of retroperitoneal sarcoma. The prognosis of soft tissue sarcomas depend on clinical and histologic characteristics. Objective: Evaluate variables that may be related to overall survival and local recurrence free survival in patients with retroperitoneal liposarcoma. Methods: retrospective analysis of medical records of 60 patients attended from 1997 to 2017, who underwent surgical resection of retroperitoneal liposarcoma.
The eribulin, a microtubule-dynamics inhibitor was approved for specific subtypes of STS. Eribulin demonstrated significantly better OS compared to dacarbazine in previously treated patients with liposarcoma and leiomyosarcoma and approved as standard treatment. However, the median progression free survival (PFS) and response rate (RR) was similar for both groups which remains modest outcome of 2.6 months of PFS and 4% of RR. Therefore, to improve antitumor activity, further combination strategy is strongly warranted. Based on the previous studies, investigators suggest phase II trial of eribulin and gemcitabine combination in previously treated patients with unresectable, advanced, or metastatic leiomyosarcoma or liposarcoma.
This phase I trial studies how well autologous NY-ESO-1-specific CD8-positive T lymphocytes (modified T lymphocytes [T cells]), chemotherapy, and aldesleukin with or without dendritic cell-targeting lentiviral vector ID-LV305 (LV305) and immunotherapeutic combination product CMB305 (CMB305) work in treating participants with sarcoma that has spread to other places in the body (advanced) or that has come back (recurrent). Modified T cells used in this study are taken from participants, are changed in a laboratory, and may "kill" some types of tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, 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. Cyclophosphamide may help the body get ready to receive the modified T cells. Interleukins, such as aldesleukin, are proteins made by white blood cells and other cells in the body and may help regulate immune response. LV305 and CMB305 may help stimulate the immune system. Giving modified T cells, chemotherapy, aldesleukin, LV305, and CMB305 may work better in treating participants with sarcoma.
Liposarcomas are the most common type of soft tissue sarcomas (STS). Among liposarcomas, well-differentiated liposarcoma (WDLPS)/dedifferentiated liposarcoma (DDLPS) are the most frequent types. WDLPS are composed mostly of mature fat whereas DDLPS contain both a WDLPS component and a non-lipomatous sarcoma component mostly of high grade. More than 50% of DDLPS will relapse locally. A significant proportion of patients will remain with a non-resectable disease that will metastasize in 20% of cases. Standard chemotherapy is poorly efficient and alternative options are so far limited. Identification of new therapeutic targets is urgent and mandatory. the recent preliminary results as well as data from the literature led us to hypothesize that the FGF (Fibroblast Growth factor)/FGFR pathway is involved in liposarcomagenesis and might therefore be a novel relevant therapeutic target in WDLPS/DDLPS. Description of the project The project associates 4 teams with a longstanding collaboration : 3 teams fom Nice (Nice University Hospital/IRCAN, Nice University Hospital, Comprehensive Cancer Center Centre Antoine Lacassagne and one team from Bordeaux (Comprehensive Cancer Center Institut Bergonié). These 4 teams are experts in the clinics, pathology and molecular genetics of sarcomas as well as in biostatistics. 1. Expression studies on the role of the syndecan-1 (SDC1)/FGFR pathway in WDLPS/DDLPS tumorigenesis The recent studies provide original results that may have a direct application in treatments of liposarcomas. They suggest that SDC1 -an effector of the FGF/FGFR pathway- might be involved in DDLPS tumorigenesis. Staff will analyse: - The pattern of expression and localisation of syndecans, FGFs and FGFRs in WDLPS/DDLPS both in a large collection of 249 primary tumors and in our in-house panel of high quality and validated human WDLPS/DDLPS cell lines. - The prognostic value of SDC1, FGF2 and FGF18 expression by correlation to the patient clinical outcomes 2. Fonctional studies of the role of the SDC1/FGFR pathway in WDLPS/DDLPS tumorigenesis. We will analyse: - The effects of modulating SDC1, FGFR expression in WDLPS and DDLPS cells on cell proliferation, cell cycle, apoptosis and on their capacity to differentiate in adipocytes. - The sensitivity of WDLPS and DDLPS cells to the FGFR inhibitor JNJ-427556493 as a single agent or in combination with other antagonists. - The mechanisms of sensitivity and resistance to JNJ-427556493 by phosphoproteomic analysis of WDLPS and DDLPS cells before and after JNJ-427556493 treatment. - The involvement of SDC1 in the dedifferentiation process of liposarcoma. Expected results staff expect to demonstrate the relevance of the SDC1/FGFR pathway in liposarcomas. We also expect to link drug activity to genomics and proteomics data. This will allow the characterization of the activity of FGFR inhibitors and the identification of powerful preclinical biomarkers of drug activity and mechanisms of resistance in DDLPS. The availability of xenograft models will allow us to validate our in vitro findings in the in vivo setting with the ultimate goal to improve patient management. The availability of an early clinical trial unit in Institut Bergonié, managed by A. Italiano, will give the immediate opportunity to transfer our data to the management of metastatic liposarcoma patients.
This phase II trial studies how well pembrolizumab and interferon gamma-1b work in treating patients with stage IB-IVB mycosis fungoides and Sezary syndrome that has come back (relapsed) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Interferon gamma-1b may boost the immune system activity. Giving pembrolizumab and interferon gamma-1b together may work better in treating patients with stage IB-IVB mycosis fungoides and Sezary syndrome.
Retrospective Evaluation of Survival after Liposarcoma
This phase Ib trial studies the side effects and best dose of ribociclib when giving together with doxorubicin hydrochloride in treating patients with soft tissue sarcomas that has spread to other places or that cannot be removed by surgery (advanced). Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as doxorubicin hydrochloride, 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. Giving ribociclib and doxorubicin hydrochloride may work better in treating patients with soft tissue sarcoma.
This trial will evaluate safety and efficacy of Letetresgene autoleucel (GSK3377794) in participants with advanced myxoid/round cell liposarcoma or high-grade myxoid liposarcoma.
Chondrosarcoma and liposarcoma consists of different subtypes with a wide range of patient survival. Current treatment options consist of wide surgical resection, however for patients with a local recurrence or metastatic disease the outcome is poor. New treatment options being evaluated and mouse models show in vivo that mammilian target of rapamycin (mTOR) inhibition can prevent tumour growth. mTOR is an kinase that is present in two complexes and thereby activates multiple pathways. Aberrant mTOR signalling is known to be involved in cancer cell survival. Several clinical studies for patients with bone or soft tissue sarcoma treated with mTOR inhibitors have been conducted and they show promising results. From these studies the investigators can conclude that the combination of an mTOR inhibitor with cyclophosphamide shows promising results in chondrosarcoma. With the lack of other treatment options for unresectable and metastatic chondrosarcoma or myxoid liposarcoma the Eurosarc consortium (www.eurosarc.eu) decided to treat these patients in a standardised way according to a common protocol with the combination of sirolimus and cyclophosphamide using the growth modulation index for evaluation in the current clinical study protocol.
This is a randomized, multicenter, double-blind, placebo-controlled, Phase 2-3 study of patients diagnosed with advanced unresectable dedifferentiated liposarcoma. Approximately 342 total patients will be randomized to study treatment (selinexor or placebo).
