Soft tissue sarcomas (STS) is generally treated by surgery, followed or preceded by radiotherapy and chemotherapy. Preoperative irradiation has been shown to be effective in a randomized trial, and is often indicated in locally advanced Soft tissue sarcomas of the limbs, in order to reach R0 resection, or in case of rapid tumor growth despite first chemotherapy. For inoperable sarcomas, radiotherapy is an efficient palliative treatment, increasing local control. Adaptive radiotherapy is defined as the set of procedures leading to the modification of a treatment plan based on the individual variations observed during irradiation. The place of this technique is increasing since the development of image-guided-radiotherapy allowing the visualization of daily variations in position, shape or volume of the tumor and organs at risk. Its implementation in current practice however remains limited because of the cumbersome processes involved (new delineation, new dose calculation, or even re-optimization) and resources to commit, especially in human time. Irradiation of soft tissue sarcomas always begins with a planning CT scan, where the target-volumes and organ at risk are delineated, and dosimetric calculations are performed prior to radiotherapy initiation. During the radiotherapy, the variations leading to a mismatch between the planned dose and the dose delivered are multiple. These may be due to positioning errors or morphological changes in the patient (weight loss), or in the tumor or organs at risk (modifications in shape, size or position). The volume of soft tissue sarcomas changes also during radiotherapy (response, progression or pseudo- progression of the tumor). However, to date, few data are available in the literature both on the volume variation of soft tissue sarcomas during preoperative radiotherapy, and on the interest of adaptive radiotherapy in the management of these tumors. It is therefore necessary to evaluate whether modifications of growth or macroscopic tumor volume are observed during the treatment, and to evaluate dosimetric impact on the target volume coverage that could impact the results of the treatment. This a prospective multicentric phase II trial conducted to evaluate the interest of adaptive radiotherapy in the preoperative or exclusive management of limb sarcomas Patients will be treated by preoperative or definitive radiotherapy for a limb soft tissue sarcomas, using an intensity-modulated conformal irradiation (with a static or dynamic technic), over 5 to 7 consecutive weeks. The total dose delivered will be of 50 Gray (preoperative radiation therapy), or 60 to 70 Gray (exclusive radiation therapy). The delineation of growth or macroscopic tumor volume,clinical target volume, and planning target volume, as well as healthy surrounding tissues will be carried out in each of the centers, and under the responsibility of the radiotherapist, on The simulation CT-scan, used for dosimetry, and 3 CT scan performed on day 1 of radiotherapy (d1), at a dose of 30Gy (d30Gy) and 50Gy (d50GY). The dosimetric re-planning according to the variations of the volume of the planning target volume will be done in case of significant variation of the target volume according to de definition mentionned in the main and secondary objectives. Main objective: The aim of this study is to evaluate the interest of adaptive radiotherapy in the preoperative or exclusive management of limb sarcomas. This is the first prospective trial focused on the evaluation of the volume variation of soft tissue sarcomas during preoperative radiotherapy, and also on the interest of adaptive radiotherapy in the management of these tumors, whereas indications of preoperative and/or exclusive radiation therapy are very frequent.
GSK-3β is a potentially important therapeutic target in human malignancies. The Actuate 1801 Phase 1/2 study is designed to evaluate the safety and efficacy of 9-ING-41, a potent GSK-3β inhibitor, as a single agent and in combination with cytotoxic agents, in patients with refractory cancers.
Introduction: Sarcomas are rare tumors of connective tissue. The exact overall incidence of sarcomas is unknown due to diagnostic difficulties and the various histological subtypes (over 80 subtypes). However, the apparent increasing incidence of sarcomas suggests environmental causes such as pesticides. Except for some specific factors (i.e. ionizing radiation, vinyl chloride, dioxin, and genetic predispositions) the scientific knowledge on the aetiology of sarcomas is sparse and inconsistent. France is a particularly appropriate country to set up a study investigating the causes of sarcoma occurrence due to the French organization in treatment and care of sarcoma patients, which is highly structured and revolved around national expert networks. The main objective of the ETIOSARC project is to study the role of lifestyle, environmental and occupational factors in the occurrence of sarcomas among adults from a multicentric population-based case-control study. Methods and analysis: Cases will be all incident cases (older than 18 years old) identified in 15 districts of France covered by a cancer registry and/or a reference center in sarcoma's patient care over a three-year period with an inclusion start date ranging from the 1st October 2018 to the 1st January 2020 and histologically confirmed by a second review of the diagnosis. Two controls will be individually-matched by sex, age (5-years group), and districts of residence and randomly selected from electoral list. A standardized questionnaire will be administered by a trained interviewer in order to gather information about occupational and residential history, demographic and socioeconomic characteristics and lifestyle factors. At the end of the interview, a saliva sample will be systematically proposed. This study will permit to validate or not already suspected risk factors for sarcomas such as phenoxyherbicides, chlorophenol and to generate new hypothesis to increase our understanding about the genetic and environmental contributions in the carcinogenicity process.
This pilot phase I trial studies how well itacitinib works in treating patients with sarcomas that do not respond to treatment (refractory) and have spread to other parts of the body (advanced/metastatic). Itacitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This phase I/II trial studies the side effects and best dose of nab-sirolimus and how well it works when given together with pazopanib hydrochloride in treating participants with nonadipocytic soft tissue sarcomas that has spread to other places in the body (advanced). Nab-sirolimus and pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This project aims to evaluate an implementable screening tool and nutritional interventions that will lead to improved quality and patient safety. The aims of this pilot study are twofold: Purpose 1: assess the prognostic value of malnutrition and sarcopenia for identifying patients at increased risk of adverse postoperative outcomes following elective or semi-elective orthopedic procedures. Purpose 2: assess the clinical benefit of postoperative oral supplementation with a commercially-available nutritional supplement that includes conditionally-essential branched chain amino acids.
T2* imaging is a method to identify labile iron pools in tumor cells. These iron pools may be linked to better treatment outcomes for specific types of therapy. This is a small pilot study to see if radiation therapy changes the amount of iron in a sarcoma tumor.
After a screening, which consists of biopsy, physical examination, initial diffusion-weighted magnetic resonance imaging (DWI-MRI), body computed tomography (CT) scan, blood tests and case analysis on Multidisciplinary Team (MDT) meeting, a patient will receive the first course of chemotherapy - doxorubicin 75 mg/sqm and ifosfamide 10 g/sqm (AI regimen) with prophylactic mesna. Then a patient will be irradiated 5x5 Gy and after radiotherapy he or she will receive two courses of AI within 4-6 weeks, depending on the tolerance. Then the response analysis in DWI-MRI and toxicity assessment and will be performed. On the second MDT meeting, a final decision about resectability of the tumor will be made. In case of resectability, a patient will be referred to surgery.
Background: A sarcoma is a rare cancer. It grows in the body's connective tissue. Sarcomas in the brain and central nervous system are especially rare. The drug Sunitinib has been approved in many countries for treating other types of rare or advanced cancers. These include kidney, pancreas, and bowel cancer. Researchers want to see if it can help people with sarcomas of the central nervous system. Objective: To study the effects of Sunitinib on gliosarcomas or sarcomas of the central nervous system. Eligibility: Adults ages 18 and older with a gliosarcoma or sarcoma of the central nervous system Design: Participants will be screened with the following tests. Some may be done as part of their regular cancer care: Medical history Medication review Physical exam Blood, heart, and pregnancy tests Cranial scans to locate and measure their tumor Participants will take Sunitinib by mouth every day for 2 weeks and then take none of the drug for 1 week. These 3 weeks equal 1 cycle. Participants will have 2 study visits in cycle 1. They will have 1 visit in all other cycles. They will answer questions about quality of life and repeat some screening tests. Participants will take their blood pressure at home weekly. They keep a diary of each dose of Sunitinib and blood pressure reading. Participants can choose to share data about their physical activity levels and quality of sleep. These participants will wear a small, portable watch-sized accelerometer device on the wrist for 6 cycles. About 1 month after their last study drug dose, participants will have a final study visit. They will have a physical exam, blood tests, and scans.
