RATIONALE: Hyperthermia therapy kills tumor cells by heating them to several degrees above body temperature. Using MRI to measure heat may help to determine the effectiveness of hyperthermia therapy. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining hyperthermia with radiation therapy and chemotherapy before surgery may kill more tumor cells and shrink the tumor so that it can be removed.
PURPOSE: This phase I/II trial is studying the side effects of hyperthermia when given together with radiation therapy and optional chemotherapy and to see how well they work in treating patients who are undergoing surgery for soft tissue sarcoma of the limbs.
- Determine the feasability and accuracy of real time magnetic resonance-based non-invasive thermometry in patients with grade 2 or 3 soft tissue sarcoma of the extremity receiving combination hyperthermia, radiotherapy, surgery, and optional high-dose ifosfamide and doxorubicin.
- Determine the local control, disease-free survival, and overall survival of patients treated with this regimen.
- Determine acute and late toxic effects of this regimen in these patients.
- Correlate measurements of tumor physiology, defined by gadolinium-enhanced magnetic resonance imaging, magnetic resonance spectroscopy, and tumor oxygenation, with clinical and/or pathological response and/or metastatic potential in patients treated with this regimen.
OUTLINE: Patients may receive high-dose ifosfamide IV continuously over 6 days (144 hours). Beginning 3 weeks after the completion of ifosfamide, patients undergo radiotherapy once daily, 5 days a week, for 5 weeks. Beginning 1 hour after radiotherapy, patients also undergo hyperthermia (with heat measured by conventional and magnetic resonance-based thermometry) over 1-2 hours once weekly for 5 weeks. Approximately 4 weeks after the completion of radiotherapy and hyperthermia, patients undergo surgery. Approximately 1 month after surgery, patients may then receive high-dose doxorubicin IV once every 4 weeks for 4 courses.
PROJECTED ACCRUAL: A total of 10-30 patients will be accrued for this study within 2-6 years.

Radiation Therapy With or Without Combination Chemotherapy or Pazopanib Hydrochloride Before Surgery in Treating Patients With Newly Diagnosed Non-Rhabdomyosarcoma Soft Tissue Sarcomas That Can be Removed by Surgery
This randomized phase II/III trial studies how well pazopanib hydrochloride, combination chemotherapy, and radiation therapy work and compares it to radiation therapy alone or in combinati...
Patients with large, high-grade extremity soft tissue sarcoma (STS) are at high risk for both local and distant recurrence. RTOG 95-14, using a regimen of neoadjuvant interdigitated chemoradiotherapy ...
Surgery (+ radiation therapy in selected cases) is standard treatment for adult-type localized soft tissue sarcoma (STS). Accumulating randomized clinical evidence also supports adjuvant chemotherapy ...
Surgery remains an integral part of the treatment of medulloblastoma. We present our experience with repeat surgery for this tumor before initiation of adjuvant therapy.
Current treatment of high-grade osteosarcoma consists of preoperative chemotherapy, typically using some combination of doxorubicin, cisplatin, ifosfamide, and/or high-dose methotrexate followed by su...

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Combined chemotherapy and radiotherapy given to augment some other form of treatment such as surgery. It is commonly used in the therapy of cancer.
Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
