Active clinical trials for "Histiocytoma, Malignant Fibrous"

RATIONALE: Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving celecoxib together with radiation therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase I trial is studying the side effects and best dose of celecoxib when given together with radiation therapy in treating patients with stage II or stage III soft tissue sarcoma of the arm, hand, leg, or foot that has been removed by surgery.

This phase III trial is studying observation to see how well a risk based treatment strategy works in patients with soft tissue sarcoma. In the study, patients are assigned to receive surgery +/- radiotherapy +/- chemotherapy depending on their risk of recurrence. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have metastatic or unresectable locally advanced soft tissue sarcoma or bone sarcoma.

This is an open label, two-stratum, phase 2 clinical trial evaluating the efficacy of 9-ING-41 in combination with gemcitabine/docetaxel in patients ≥10 years of age with advanced sarcoma. 9-ING-41 in combination with gemcitabine and docetaxel will lead to sustained disease control and/or increase the rates of objective response in patients with unresectable or metastatic soft tissue and bone sarcomas.

9-ING-41 in combination with gemcitabine and docetaxel will lead to sustained disease control and/or increase the rates of objective response in patients with unresectable or metastatic soft tissue and bone sarcomas. This is an open label, two-stratum, phase 2 clinical trial evaluating the efficacy of 9-ING-41 in combination with gemcitabine/docetaxel in patients ≥10 years of age with advanced sarcoma. Stratum A: Patients with advanced soft tissue sarcoma previously treated with 0-3 prior lines of systemic therapy will receive 9-ING-41 twice weekly with gemcitabine on days 1 and 8 and docetaxel on day 8 of a 21-day cycle until disease progression or unacceptable toxicity. Stratum B: Patients with relapsed or refractory bone sarcoma previously treated with at least one line of systemic therapy will receive 9-ING-41 twice weekly with gemcitabine on days 1 and 8 and docetaxel on day 8 of a 21-day cycle until disease progression or unacceptable toxicity. Disease response assessment will be performed every 2 cycles (6 weeks) for the first 8 cycles (24 weeks), then every 12 weeks thereafter.

The investigators hypothesize that combination anlotinib with toripalimab will improve progression-free survival relative to historical controls in patients with Unresectable or Metastatic Undifferentiated Pleomorphic Sarcoma.

After a screening, which consists of biopsy, physical examination, initial diffusion-weighted magnetic resonance imaging (DWI-MRI), body computed tomography (CT) scan, blood tests and case analysis on Multidisciplinary Team (MDT) meeting, a patient will receive the first course of chemotherapy - doxorubicin 75 mg/sqm and ifosfamide 10 g/sqm (AI regimen) with prophylactic mesna. Then a patient will be irradiated 5x5 Gy and after radiotherapy he or she will receive two courses of AI within 4-6 weeks, depending on the tolerance. Then the response analysis in DWI-MRI and toxicity assessment and will be performed. On the second MDT meeting, a final decision about resectability of the tumor will be made. In case of resectability, a patient will be referred to surgery.

After a screening, which consists of biopsy, physical examination, initial diffusion-weighted magnetic resonance imaging (DWI-MRI) or body computed tomography (CT) scan, blood tests and case analysis on Multidisciplinary Team (MDT) meeting, a patient will receive the hypofractionated radiotherapy 10x 3.25 Gy with regional hyperthermia (twice a week) within two weeks. The response analysis in CT or DWI-MRI and toxicity assessment will be performed after at least 6 weeks. At the second MDT meeting, a final decision about resectability of the tumor will be made. In case of resectability or consent for amputation, if required, a patient will be referred to surgery. In case of unresectability or amputation refusal, the patient will receive the second part of the treatment which consists of 4x 4 Gy with hyperthermia (twice a week).

RATIONALE: Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy with or without radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase III trial is studying how well giving ifosfamide and doxorubicin, radiation therapy, and/or surgery works in treating young patients with localized soft tissue sarcoma.

RATIONALE: Glutamine may help prevent mucositis, or mouth sores, in patients receiving chemotherapy for sarcoma. It is not yet known whether glutamine is more effective than a placebo in preventing mucositis in patients receiving chemotherapy for sarcoma. PURPOSE: This randomized clinical trial is studying glutamine to see how well it works compared to a placebo in preventing oral mucositis in patients receiving chemotherapy for sarcoma.
