Active clinical trials for "Sarcoma"

RATIONALE: Learning about the effect of nutritional supplements on quality of life in patients receiving chemotherapy for cancer may help doctors plan the best treatment. PURPOSE: This randomized phase II trial is studying nutritional supplements to see how well they work in improving quality of life during first-line chemotherapy in patients with metastatic gynecologic cancer.

Soft tissue sarcomas (STS) are a group of rare mesenchymal neoplasms affecting all ages. STS most commonly present as localised disease but despite surgery and adjuvant treatment more than half of patients will develop recurrent or metastatic disease. Leiomyosarcoma (LMS), a malignancy of smooth muscle, is one of the most common STS and undifferentiated pleomorphic sarcoma (UPS) is a common sarcoma sub-type with aggressive symptoms. Recent studies have demonstrated reasonable sensitivity of LMS to gemcitabine monotherapy with an objective response rate of 8-19%. However the overall survival is still only about 12 months which illustrates the critical clinical need for improved therapies for advanced STS and sarcoma in general. In this study the investigators propose to combine the immune synapse checkpoint inhibitor with the cytotoxic and immune modulating agent, gemcitabine. It is hoped that this dual immunomodulatory approach will enhance the effect of pembrolizumab on PD-L1 expressing LMS and UPS, leading to a safe treatment with patient outcomes. This is a two part, phase I, single centre dose escalation and dose expansion study in the total of 24 patients with newly diagnosed metastatic or inoperable LMS and UPS. There will be approximately 12 patients in the dose escalation cohort (part A) and the starting dose will be a fixed dose rate (FDR) gemcitabine of 800 mg/m2 on day 1 and 8 of 21 days cycles in combination of 200 mg of pembrolizumab given as an infusion on day 1 every 3 weeks. The MTD cohort (part B) will then be expanded to a total of 12 patients in order to further evaluate the safety and tolerability of that dose as well as to preliminarily assess response to therapy. The study is sponsored by Royal Marsden NHS Foundation trust and the funding for the study is provided by Merck Sharp & Dohme Limited.

In order to describe functional impact of surgery in elderly patients treated for lower-limb soft-tissue sarcoma, the investigators set up this project which aims to identify prognostic factors among geriatric and functional assessment.

RATIONALE: Radiation therapy can cause long-term adverse effects. Hyperbaric oxygen therapy may be effective in lessening gastrointestinal symptoms caused by radiation therapy given for pelvic cancer. It is not yet known whether high-pressure oxygen is effective in treating adverse effects caused by radiation therapy. PURPOSE: This randomized phase III trial is studying hyperbaric oxygen therapy to see how well it works in treating long-term gastrointestinal adverse effects caused by radiation therapy in patients with pelvic cancer.

This research trial studies the immune changes following trabectedin in patients with sarcoma that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Analyzing tumor tissue may help to understand the changes in immune cells in or around the tumor or if there is an increase in immune cells in the tumor after receiving trabectedin.

Anthracycline antibiotics are included in the chemotherapy regimens of approximately 82% of patients with bone cancer and 44% of those with soft tissue sarcoma diagnosed in childhood or adolescence. Impaired cardiac function occurs after treatment with anthracyclines. The frequency of impairment increases with increasing cumulative dose. There are inadequate data regarding the relationship between doxorubicin administration and changes in serum levels of cardiac troponin T (cTn-T) or I (cTn-I), N-terminal (NT) brain natriuretic peptide (BNP), or tissue Doppler imaging parameters. This non-therapeutic study proposes a prospective, single arm study of serial changes in tissue Doppler imaging parameters, cTn-T and NT-BNP in children and adolescents with malignant bone and soft tissue tumors whose planned chemotherapy includes treatment with ≥ 375 mg/m2 of doxorubicin. The proposed study will rigorously evaluate the usefulness of serial determinations of tissue Doppler imaging, cTn-T and NT-BNP for very early identification of anthracycline-related myocardial injury. Demonstration that one or more of these markers identifies subclinical myocardial damage and that biomarker or tissue Doppler imaging parameters exhibit a dose-response relationship with cumulative doxorubicin dose would facilitate intervention trials in patients at risk for anthracycline cardiomyopathy.

This perspective, mono institutional study is addressed to find potential serum and urine biomarkers predictive of the pharmacokinetic and pharmacodynamic profile of soft tissue sarcomas patients treated with trabectedin.

This is a prospective observational study in which patients with untreated retroperitoneal sarcoma will have Magnetic Resonance Imaging (MRI) prior to surgery. In addition, patients who will be undergoing pre-operative radiotherapy will have an additional MRI scan at two weeks post radiotherapy. For both groups, the magnetic resonance images will be correlated with tumour pathology. The study hypothesis is that Magnetic Resonance Imaging will provide a more accurate assessment of tumour volume and local staging than CT and will identify areas of altered oxygenation, cellularity and perfusion which change in response to radiotherapy before tumour shrinkage occurs.

The purpose of the study is to assess the functional outcome, quality of life and late sequelae in a representative sample of 600 long-term survivors of Ewing sarcoma and to build a unique clinical and functional data pool of the underlying cohort of 3000 Ewing sarcoma patients with a follow-up of 3 decades.

The purpose of this study is to assess the feasibility of conducting a large hospital based case control study of the role of dioxins and dioxinlike polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs).
