Active clinical trials for "Fibromatosis, Aggressive"

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiation therapy in treating patients who have aggressive fibromatoses.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy with vinblastine and methotrexate in treating children who have desmoid tumors that are recurrent or untreatable with surgery or radiation therapy.

In this study Drug-eluting microbeads (DEB) loaded with Doxorubicin will be delivered into the target Desmoid Fibromatoses (DF) tissue via selective arterial embolization by angiographic technique. The objective of the study is to demonstrate the safety and efficacy of this treatment.

This randomized phase III trial compares the effects, good and/or bad, of sorafenib tosylate in treating patients with desmoid tumors or aggressive fibromatosis. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the proteins needed for cell growth. [Funding Source - FDA OOPD]

Desmoids tumors are benign soft tissues tumors characterized by aggressiveness and potential local recurrence. There is a female predominance with a sex ratio of 2/1 and median age at diagnosis is about 30 years. Only a complete surgical excision is recommended in desmoids tumors. Some forms of desmoid tumors are recurrent and/or symptomatic and are not accessible to a conservative surgical treatment. In these clinical situations, only a medical treatment may achieve tumor control and quality of life maintenance. Place of systemic treatments in the management of desmoids tumors is poorly evaluated. Regarding chemotherapy, methotrexate and vinblastine protocol is actually the best evaluated combination, which allowed observing objective response rate between 40 and 75%. Toxicity was mainly marked by the risk of haematological toxicity. Pazopanib is an inhibitor of multi-target tyrosine kinase, in oral form, with selective type receptors -1, -2 and -3 of VEGF receptors on the PDGFA and B, and c-Kit. It is currently under clinical development in humans in the treatment of several tumor types.

A two-cohort, fase II, open-label, non-randomized, multicenter clinical trial. 14 sites in Spain. Cohort 1: Subjects with desmoid tumor (DT) Cohort 2: Subjects with desmoplastic small round cell tumor or Ewing sarcoma (DSRCT and ES) Nab-paclitaxel (ABRAXANE) will be administered as follows: Age ≥ 21 and ≤ 80 years: 125 mg/m2 days 1, 8 and 15 in cycles of 28 days Age ≥ 6 months and ≤ 20 years: 240 mg/m2 days 1, 8 and 15 in cycles of 28 days Subjects in the DT cohort will receive a maximum of three cycles. Subjects in the DSRCT and ES cohort will receive unlimited cycles until disease progression, the subject begins a new anticancer treatment, withdrawal of parent/guardian/subject consent/assent, parent/guardian/subject refusal, physician decision, toxicity that cannot be managed by dose delay or dose reduction alone or the study ends for any reason. The main goal is to determine the objective response rate (ORR), using RECIST 1.1 criteria and to determine the clinical benefit rate (CBR), defined as CR+PR+SD for 3 months with improvement of pain with at least minimally important difference (MID) of 2 in subjects with desmoid tumors (DT cohort) and to determine the objective response rate (ORR) in subjects with desmoplastic small round cell tumor and Ewing sarcoma, using RECIST 1.1 criteria (DSRCT and ES cohort)

RATIONALE: Estrogen can stimulate the growth of cancer cells. Hormone therapy using toremifene may fight the growth of desmoid tumors by reducing the production of estrogen. PURPOSE: Phase II trial to study the effectiveness of toremifene in treating patients with desmoid tumors.

The purpose of this study is to determine whether Imatinib Mesylate is active in diseases - such as Desmoid Tumor and Chondrosarcoma - expressing the receptor for the platelet-derived growth factor (PDGF) both in its isoform alpha and beta

Desmoid tumors (DT) are rare tumors (2-4 cases/million/year) that originate from musculoaponeurotic structures. Although they are benign tumors with no metastatic potential, DT are considered as locally aggressive tumors, with local invasiveness and tissue destruction, leading to pain, and disability. Surgery remains the keystone of therapy, but is limited by the anatomical situation of extra-abdominal desmoid (EAD) tumors (chest wall, root members). In patients where surgery is considered, negative-margin resection (R0) is recommended, but this frequently results in cosmetic/functional impairment. Moreover, prognostic impact of R0 resections remains controversial. The outcome after initial surgery depends upon several factors such as age, tumor site, and tumor size as demonstrated by recent data from the French Sarcoma Group. Alternative therapies to DT surgery for front-line or recurrence include NSAID's, anti-estrogens alone or in combination, -interferon, chemotherapy, targeted therapies or radiation therapy. All of these medical approaches however may fail to achieve long-term disease control and a number of patients suffer from irreducible pain, and disability from tumor volume. Cryoablation is a promising technique that is suitable for patients experiencing extra-abdominal DT. The procedure is based on repeated cycles of freezing/passive thawing of the tumor, leading to cell death. The technique has many advantages, among which: the accurate control of iceball under real-time MRI or CT-scan monitoring (that is not possible with other techniques such as radiofrequency), the lack of mutilation, the possibility of repeating the procedure. The cryoablation procedure has proven to be beneficial for the treatment of various tumors (liver metastases, breast, kidney). Recently, percutaneous cryotherapy has been reported in the treatment of EAD tumors poorly suited to surgery, with promising results. In the light of these encouraging data, it is believed that patients with extra-abdominal DT not amenable to surgery unless unacceptable surgical sequel and progressing after at least two lines of adequate medical therapy (tamoxifen, NSAID or chemotherapy), could benefit from the cryoablation procedure. Tumor cryotherapy-induced regression should allow symptoms relief, prolonged progression-free survival and a better quality of life.

The purpose of this study is to examine the response rate of desmoid tumors to hydroxyurea. The investigators hypothesize that hydroxyurea will be a safe, non-toxic alternative to aggressive surgery or chemotherapy for this difficult to treat tumor.
