Active clinical trials for "Soft Tissue Neoplasms"

To determine if MRI imaging can be used to accurately determine if a sarcoma is responding to the type of chemotherapy being used.

Registration of all sarcoma patients treated at a specialized sarcoma center in Switzerland.

Bone tumor near the articular cartilage is hard to remove sufficiently without damaging adjacent joint. The purpose of this study was to evaluate the feasibility of navigation-assisted surgery for saving joint in bone tumor resection or curettage. In this study, the investigators hypothesized that computer-assisted surgery is feasible method to get both enough margin and joint salvage. Each of them is important intermediate factor for either oncologic outcome or functional outcome respectively. The investigators designed this study to find what proportion of patients who underwent computer-assisted resection could get enough margins using some criteria obtained by overlapping preoperative and postoperative images. The investigators also evaluated whether computer-assisted surgery can be feasible for joint saving using some criteria including functional outcome.

The randomized, controlled trial is aiming at comparing local control rate between two surgical resections, barrier resection and local wide resection with 1cm or equivalent normal tissues. This is based on the fact that the goal of local surgical treatment is to remove the tumor with negative margin and best functional outcome, but there is a lack of standard principle of surgery. Some surgical oncologists recommended enlarging surgical field in which case the associated muscle was removed from origin to insertion, the previous surgical scar and radiation field were also grossly remove, though there would be extra trauma and unacceptable function impairment, they believe that patients would benefit from "big operations". Most other surgeons would perform a sarcoma resection through normal tissues, and reported a fair local control as long as a negative margin was obtained. As reported by various authors, recurrent STSs are associated with higher risk to develop further recurrence as compared to primary STSs, thus, efforts should focus on this category of STSs to improve outcome.

The aim of the study is to evaluate the benefit of the acupuncture as healing modalities in the therapy of acute toxicity of radiotherapy.

The aim of the present study is to investigate the incidence of chronic pain following breast cancer surgery in Cyprus, discover its associated risk factors and explore the impact of Pecs Blocks on the appearance of post mastectomy chronic pain symptoms

The aim of this study is to identify demographic & disease characteristics in pediatric oncology patients diagnosed with soft tissue & bone tumors involving the extremities & treatment outcomes in these patients.

The aim of this study is to identify demographic & disease characteristics in pediatric oncology patients diagnosed with Ewing Sarcoma Family of Tumors (ESFT) & treatment outcomes in these patients.

The purpose of this study is to determine whether 18F-Al labeled RGD is safety and effective for cancer diagnosis and therapy response.

Radiofrequency ablation is used to treat patients with many different conditions. It is used to treat heart arrhythmia and benign bone tumors, and to control bleeding during surgery. It has been approved by the Food and Drug Administration for soft tissue ablation (removal). The technique involves inserting a probe, guided by computed tomography or ultrasound, and sending radio waves through the probe. The radio waves generate heat, which both destroys adjacent tissue and cauterizes blood vessels. This study will enroll 15 adults (age 18 or older) with soft tissue metastases who suffer pain that is not well controlled by other means, such as drugs. The goal is to reduce their pain or their use of analgesics by partially destroying some of their tumors. Patients will be ineligible for the study if they change the class of pain medication they use within 2 weeks before or 2 weeks after the study treatment. Patients will fill out short questionnaires about pain and daily activities (Brief Pain Inventory) before treatment and 1 day, 1 week, 1 month, 3 months, and 12 months after treatment to ascertain whether their pain is better controlled with less pain medication. For the treatment, most patients will receive local anesthetic in the area where the probe is inserted. Some patients may require general anesthesia. The probe will remain in place typically for 10 to 30 minutes. For larger tumors, it may be inserted at different positions.
