Bone Sarcoma

This study evaluates the effectiveness of intraoperative indocyanine green dye and fluoroscopic technology in confirming negative margins after tumor removal.

Survivors of bone and soft tissue sarcoma often face long-term health problems after their cancer treatment, such as muscle weakness, joint stiffness, and reduced heart and lung fitness. Because of this, many survivors are less physically active than their healthy peers, which can further increase their risk of heart disease and other late effects later in life. This study, called "Sport ist Herzenssache" ("Sports is a Matter of the Heart"), tests whether a personalized exercise program can help young survivors (aged 15-39) become more physically active. All participants receive a fitness tracker (smartwatch) to monitor their daily activity. Half of the participants are randomly assigned to also receive an individualized home exercise plan, including strength and endurance training, with some sessions guided online by an exercise specialist. Before and after an 8-week exercise period (with continuous activity tracking for about 13 weeks total), participants complete simple physical tests (such as walking and balance tests), a heart and fitness check-up, and questionnaires about their quality of life and energy levels. The main goal is to find out whether the personalized exercise plan helps participants become more active in daily life, measured in minutes of moderate-to-intense activity per day. The study also looks at effects on heart health, physical function, and overall well-being. The results will help determine whether structured exercise support should become a standard part of long-term follow-up care for young sarcoma survivors.

This study will evaluate strategies to improve physical function and promote exercise and physical activity in adolescents and young adults (AYAs) with sarcoma. The study will assess the feasibility of a standardized triage system for referring AYAs with sarcoma to appropriate exercise and rehabilitation services, and will also examine changes in physical function and health-related quality of life before and after a 12-week personalized exercise program.

This phase II trial tests how well zanzalintinib (XL092) works in treating patients with leiomyosarcoma that has spread from where it first started to other places in the body (metastatic) or that cannot be removed by surgery (unresectable). Leiomyosarcomas are a type sarcoma that can occur in any location in the body, such as the uterus or in the abdomen. Current standard treatment for leiomyosarcoma only shows a progression-free survival of 4-6 months. XL092, a tyrosine kinase inhibitor, interferes with cell communication and growth and may prevent tumor growth. Giving XL092 may kill more tumor cells in patients with metastatic or unresectable leiomyosarcoma. The trial has now been expanded to treat additional sarcoma types that are sensitive to tyrosine kinase inhibitors (TKIs) such as translocation-associated soft tissue sarcoma (such as synovial sarcoma), and bone sarcoma (including osteosarcoma and Ewing sarcoma).

This study will evaluate whether a short nutritional intervention before surgery can improve recovery in patients with bone and soft tissue sarcomas. Patients with these tumors often have a higher risk of poor nutrition and loss of muscle mass. These problems may increase the risk of complications after major orthopedic surgery. Participants will be randomly assigned to one of two groups. One group will receive a special oral nutritional supplement twice daily before surgery, in addition to standard care. The other group will receive standard care without the preoperative nutritional supplement. The main aim of the study is to compare the rate of clinically relevant postoperative complications within 30 days after surgery. The study will also evaluate changes in muscle mass on CT scans, blood markers of nutrition and inflammation, nutritional risk, functional status, length of hospital stay, and tolerance of the nutritional supplement.

The purpose of this study is to investigate the feasibility of early access to mental healthcare during sarcoma treatment as well as to assess the association between early access to psychiatric care and depression, anxiety, postoperative outcomes, and patient satisfaction in patients undergoing surgery for musculoskeletal sarcoma.

The purpose of this study is to look at the amount of function that returns in participants that have reconstruction with bone graft or artificial device and in participants who have tumor surgery plus regenerative osseous surgery. The study will look at the level of function for a period of 3 years after the surgery. Another purpose of this study is to look at how well the bone heals in participants undergoing regenerative surgery

Primary bone and soft tissue sarcomas are an exceptionally rare form of cancer, collectively accounting for only 1% of all malignancies diagnosed. Sarcomas often occur in the patients' extremities and treatment typically involves limb salvage surgery with bone and/or muscle resection. These surgeries often leave the patients with disfigurements, psychological trauma, and functional disabilities. Perhaps, the most difficult and life-altering decision that patients (and their parents) with primary bone sarcomas about the knee joint have to make, involves choosing the type of surgical procedure that will provide them with the outcome that meets their functional as well as aesthetic expectations. In literature, the quality of life for patients with osteosarcoma around the knee joint after three different surgical procedures, that is, amputation, endoprosthetic reconstruction and rotationplasty was evaluated. There was found that patients treated with rotationplasty showed significantly higher functional scores compared to the two other groups of patients. Also, researchers investigated the long-term quality of life after bone sarcoma surgery around the knee joint and found that, despite the functional disability, survivors were busy with work, study, relationships, and sometimes they have founded a family. Most published reports in the literature on assessment of gait in the lower-extremity sarcoma survivors were focused on bone sarcoma patients after wide resection and endoprosthetic reconstruction. To the knowledge of the investigator, there has been no published studies on gait analysis after resection of soft tissue sarcomas (STS) of the lower extremity. The rare and heterogeneous aspects of STS and the paucity of knowledge of movement strategies in these patients hinder the development of effective rehabilitation protocols for recovering movement after resection of STS in the lower limb.

This study compares carbon ion therapy, surgery, and proton therapy to determine if one has better disease control and fewer side effects. There are three types of radiation treatment used for pelvic bone sarcomas: surgery with or without photon/proton therapy, proton therapy alone, and carbon ion therapy alone. The purpose of this study is to compare quality of life among patients treated for pelvic bone sarcomas across the world, and to determine if carbon ion therapy improves quality of life compared to surgery and disease control compared with proton therapy.

This is a multicenter phase II study concerning patients with high-grade bone sarcoma (HGBS) without complete remission after standard treatment at diagnosis or at relapse. Patients will be treated with regorafenib + best supportive care (BSC) for a maximum of 12 months as maintenance therapy after standard line therapy completion. Progression free rate (PFR) data will be collected and analysed for all included patients to evaluate if regorafenib + BSC can be considered as an interesting treatment for further investigations in this indication.

Randomized, non-comparative, multicentre exploratory phase II study. Two arms concerning patients with bone sarcoma after the first line therapy: in the first arm, patients will be treated with Regorafenib for a maximum of 12 months as maintenance therapy after first line therapy, whereas in the second arm, patients will be kept under surveillance (standard of care). Regardless of their study arm, all the patients will be followed up until end of the study. The comparison between these two arms will allow to determine whether or not regorafenib is efficient for disease control, in terms of Relapse-Free Survival improvement.

Sarcoma which has spread to the lungs is most often treated with surgery. Even with surgery, most patients will not be cured and will die from their disease, probably because of small cancer cells that are present in the lungs at the time of surgery, but cannot be seen or detected. It is for this reason that we are looking for a better treatment. Giving chemotherapy after surgery is generally not recommended because it has significant side effects and no benefit has been proven. This study is investigating a new technique for delivering chemotherapy directly into the lungs at the time of surgery. Delivering chemotherapy directly to the lungs could potentially kill any microscopic cancer cells that are present in the lungs at the time of surgery, while sparing other major organs in the body from the side effects of chemotherapy. This technique is called In Vivo Lung Perfusion (IVLP). This is a Phase I, non-randomized, dose escalation study that will act as a pilot study for a larger prospective, multicenter, controlled clinical trial. Patients who have bilateral disease will have one lung undergo IVLP and the other lung will remain untreated with the IVLP (the other lung will be treated as current standard of care - either surgery or radiation) as a control lung. The patients will undergo a posterolateral thoracotomy. Lung metastases will be identified by visualization or palpation. After surgical isolation of the lung by proximal control of pulmonary artery and veins, IVLP will be initiated. After 3 hours of IVLP, the lung metastases will be removed in the usual fashion. Patients will be cared for post-surgery according to institutional standards. The patients will be followed for up to 2 years. The primary endpoint is safety. Secondary endpoints include additional safety endpoints and efficacy.

Post-authorisation, multicentric, observational, retrospective and prospective study to assess quality of care of sarcoma patients in expert and non-expert centers by analysing correlation of quality items and outcomes such as relapse free survival, overall survival, percentage of amputation, etc. Expert pathology peer review will be performed to detect differences between expert and non-expert centers as well as differences in treatment and patient prognosis. Tumor samples of 4 types of sarcoma would also be included in translational research to detect biomarkers and produce preclinical models.

Data from 40 patients are planned to be included in the study to randomize approximately 10 patients. This study involves patients with advanced/metastatic GD2-positive rhabdomyosarcoma after progression on 1st line of chemotherapy, advanced/metastatic GD2-positive Ewing sarcoma after progression on 1st line of chemotherapy and advanced/metastatic GD2-positive osteosarcoma after progression on 1st line of chemotherapy. All patients will receive therapy until disease progression (a total of 6 courses of immunotherapy). The primary objective of the study is to determine the efficacy and safety of dinutuximab beta with investigator's choice of chemotherapy.

The Registry For Children, Adolescents And Adults With Osteosarcoma And Biologically Related Bone Sarcomas (COSS-Registry) is a non-interventional, multicentric, international, clinical and epidemiologic patient registry. The COSS-Registry collects key data on osteosarcomas or biologically related bone sarcomas. With that data collection we want to gain new scientific insights and results about this tumor disease, prognosis, surveillance and long-term effects. Besides the data collection we would also like to foster the collection of biomaterial (tumor specimen and blood samples) for scientific research. The stored material will be used to perform cell and molecular biological analyses to identify the causes of osteosarcoma, the prognosis and possible new treatment options. As a starting point the donated biomaterial of registered patients will be analyzed firstly for the presence of a tumor predisposition by germline mutations. In case of detected genetic variations that are related to the tumor disease and which may affect the patient's health and follow-up care (because of the potentially increased risk of developing other malignant tumors), affected patients will be informed and referred to genetic counseling. Registry patients will be asked at the time of diagnosis if they wish to be informed about germline variants detected as part of the study procedures.
