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.
This study evaluates the effectiveness of intraoperative indocyanine green dye and fluoroscopic technology in confirming negative margins after tumor removal.
Epithelioid hemangioendothelioma (EHE) is an ultra-rare sarcoma, marked by distinctive molecular and pathological features and with a variable clinical behavior. Its natural history is still partially understood, reliable prognostic and predictive factors are lacking and many questions are still open on the optimal management. In the context of EURACAN, a prospective registry specifically dedicated to EHE was developed and launched with the aim of providing, through high-quality prospective data collection, a better understanding of this disease. The study design is a registry-based cohort study including only new cases of patients with a pathological and molecularly confirmed diagnosis of EHE. The objectives are to improve the understanding of EHE natural history, validate and identify new prognostic and predictive factors, clarify the activity and efficacy of currently available treatment options, describe treatment pattern. It is an hospital-based registry established in centres with expertise in EHE including adult patients with a new pathological and molecularly confirmed diagnosis of EHE starting from the 1st December 2023. The characteristics of each patient in the facility who meets the above-mentioned inclusion criteria will be collected prospectively and longitudinally with follow-up at cancer progression and / or cancer relapse or patient death. The data analyses will include descriptive statistics and analytical analyses. Multivariable Cox's proportional hazards model and Hazard ratios (HR) for all-cause or cause-specific mortality will be used to determine independent predictors of overall survival, recurrence and progression. The registry has been joined by 21 sarcoma reference centers across EU and UK, covering 10 countries. Patients' recruitment started in December 2023. The estimated completion date is December 2033 upon agreement on the achievement of all the registry objectives. The already established collaboration and participation of EHE patient's associations involved in the project will help in promoting the registry and fostering accrual. This registry has been developed with the support of EHE Rare Cancer Charity UK, STATER (Grant Agreement number: 947604, HP-PJ-2019) and EURACAN 2022 (Grant Agreement number: 101085486, EU4H-2022-ERN-IBA) European Health and Digital Executive Agency (HaDEA)
"Blood and Tissue Extraction for Immunological Examinations During Neoadjuvant Therapy of Soft Tissue Sarcoma" is a prospective study with additional translational research using preoperative and postoperative tissue, blood sampling and advanced imaging.
Background: Kaposi sarcoma (KS) is a type of tumor caused by the Kaposi sarcoma herpesvirus. KS usually affects the skin, but lesions can also appear in the lymph nodes, lungs and digestive tract. KS is most common in people with compromised immunity, but it also appears in otherwise healthy people. Researchers want to understand more about how KS develops, why it may recur, and how it affects the immune system and organs. Objective: To learn more about the natural history of KS. Eligibility: People aged 18 years and older with KS. Design: Participants will be screened. They will have a physical exam with blood tests. They will have an imaging scan. They may need a new biopsy: Tissue samples may be cut from their tumor. Their ability to perform normal activities will be assessed. Participants will visit the clinic to have their KS evaluated. In addition to the imaging scans and other tests performed during screening, procedures may include: Eye exam. Ultrasound exam of the heart (electrocardiogram). Collection of saliva and urine samples. Biopsies of the skin or lymph nodes. Swabs of the anus and cervix. Photographs of skin lesions. Removal of fluid samples from the space around the lungs, intestine, or heart. The evaluation visit will be repeated 5 more times over 18 months and then yearly for up to 10 years. Participants will follow their standard treatment for KS during the study.
The investigators explored the safety and activity of weekly irinotecan liposomes in patients with relapsed and metastatic Ewing Sarcoma.
This phase I/II trial studies the side effects and best dose of proton-spatially fractionated radiotherapy (P-SFRT) and to see how well it works with standard radiation therapy in treating patients with newly diagnosed retroperitoneal soft tissue sarcoma. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Standard spatially fractionated radiotherapy (SFRT) refers to how the radiation is delivered to the tumor. SFRT means that different parts of the tumor are receiving different doses of radiation (fractionation) through beams that allow areas of higher and lower (peaks and valleys) of doses of the radiation. This spatial fractionation allows an overall high-dose radiation to be given in the peaks and those areas of the tumor may release cells and substances that may help with killing tumor cells, reducing tumor symptoms and shrinking tumors. Proton therapy is a type of radiation therapy that can overcome some of the barriers of standard SFRT. Protons are tiny radioactive particles that can be controlled in a beam to travel up to the tumor and, compared to the particles used in standard radiotherapy, proton therapy can deliver higher doses to the tumor because smaller doses of radiation are delivered to tissues away from the tumor. This allows radiation therapy dose-escalated (continuously increasing the dose of radiation) treatment to tumors even though the tumor is near radiation sensitive organs like the colon. Giving P-SFRT with standard radiation therapy may work better in treating patients with newly diagnosed retroperitoneal soft tissue sarcoma.
Technologies 3D are demonstrating enormous potential for innovation in the field of surgery,introducing the concept of "treatment customization" (from planning surgery to implant design and manufacturing) on the patient's anatomy, simply by taking advantage of the patient's own common diagnostic images and the flexibility of 3D printing. In fact, this new construction technology allows the construction of the complex anatomical geometries with economy, simplicity and on scales of production unattainable by other traditional technologies.

The main aim of the study is evaluate quality of life and motor performance of patients with soft tissue sarcomas undergoing surgical treatment and post-operative rehabilitation treatment. Primary objectives: - Identification of clinical characteristics and motor damage after surgery for soft tissue sarcomas; - Impact of perioperative treatments and surgery on the quality of life of patients with soft tissue sarcomas; - Impact of post-operative rehabilitation treatment on quality of life and recovery of motor activity The primary endpoint will be the improvement in the Toronto Extremity Salvage Score (TESS) between T1 (post-surgery) and T3 (at the end of rehabilitation treatment). Secondary endpoints will be: 1. the evolution over the various timepoints of the selected rating scales (Toronto Extremity Salvage Score, Musculoskeletal Tumor Society Rating Scale, Numerical Rating Scale, Brief Pain Questionnaire, Douleur Neuropathique en 4 Questions, Leeds Assessment of Neuropathic Symptoms and Signs Scale, European Organization for Research and Treatment of Cancer, Quality-of-Life Questionnaire (QLQ)-C30, Short Form Health Survey 36); • The change in walking performance before and after the rehabilitation treatment.
This is a multi-center, single arm, open-label, localized pharmacodynamic biomarker Phase 0 trial designed to study the biological effects within the tumor microenvironment of PBA-0405 when administered intratumorally in microdose quantities via the CIVO device.
