To study the activity and toxicity of a neoadjuvant regimen including high-dose ifosfamide in combination with radiotherapy, and subsequent surgery, in high-risk soft tissue sarcomas.
This is a phase II multicenter study designed in two phases. A total of 32 patients will be included in 10 hospitals belonging to the Spanish Group for Research in Sarcomas (GEIS). Selection criteria are: patients with localized soft tissue sarcoma from the extremities or trunk with high-risk features (>5 cm and grade 2-3), or recurrences after prior inadequate surgery. The treatment schedule will be: initial biopsy, 3 cycles of high-dose Ifosfamide, 12 gr/m2 in 5 days, concurrent with Radiotherapy 50 Gy, and subsequent wide surgery. To assess the predictive factors of response to the combination therapy, DNA and RNA extraction will be performed on the pretreatment biopsies. DNA will be used to hybridize Affymetrix GeneChip® Human Mapping 500K Array, which allows for the study of 500000 SNPs throughout the genome. The expression of 39000 RNA transcripts will be evaluated employing the Affymetrix Genechip Human Genome HG-U133 Plus 2.0, and validated by real-time RT-PCR.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether ifosfamide or doxorubicin is more effect...
SSG XX is a phase II trial for high-risk soft tissue sarcomas (STS) of the extremities and trunk wall. Prognostic factors (histopathological markers) are used to identify high-risk tumors....
The purpose of this study is to determine the maximum tolerated dose of the TLC D-99 combined with ifosfamide and then the efficacy of this combination in terms of overall response rate, t...
The purpose of this study is to evaluate the safety of ifosfamide when added to the combination regimen of olaratumab and doxorubicin in participants with advanced or metastatic soft tissu...
Complete resection is still the only curative treatment option in patients with soft tissue sarcoma (STS). Patients with a non-resectable STS have a dismal prognosis even without evidence ...
The objective of this study was to analyze outcomes for patients with soft tissue sarcoma of the extremities using neoadjuvant ifosfamide-based chemotherapy and hypofractionated reduced dose radiother...
Clinically, understanding how the soft tissue envelope adapts to various forms of hip dysfunction could enhance both surgical and nonsurgical management. Very few studies have looked at soft tissue st...
This study using three-dimensional cone beam computed tomography (CBCT) images of children determined relationships between nasal skeletal and soft tissue measurements and assessed the association wit...
Gustilo-Anderson IIIB tibial fractures and infected tibial nonunions represent particular challenges for the orthopaedic trauma surgeon. Debridement of dysvascular bone and soft tissues can create com...
Endemic fungal infections can present atypically and should be considered in the differential diagnosis of any soft tissue infection not responding appropriately to antibiotic therapy. Diagnosis can b...
Injuries of tissue other than bone. The concept is usually general and does not customarily refer to internal organs or viscera. It is meaningful with reference to regions or organs where soft tissue (muscle, fat, skin) should be differentiated from bones or bone tissue, as "soft tissue injuries of the hand".
The assessment, treatment, and management of soft tissue injury or dysfunction. Therapy is designed to reduce tension and irritation in affected tissues and may include MASSAGE; muscle stretching, or direct pressure on muscles, connective tissue, and TRIGGER POINTS.
Infections of non-skeletal tissue, i.e., exclusive of bone, ligaments, cartilage, and fibrous tissue. The concept is usually referred to as skin and soft tissue infections and usually subcutaneous and muscle tissue are involved. The predisposing factors in anaerobic infections are trauma, ischemia, and surgery. The organisms often derive from the fecal or oral flora, particularly in wounds associated with intestinal surgery, decubitus ulcer, and human bites. (From Cecil Textbook of Medicine, 19th ed, p1688)
Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue.
A sarcoma containing large spindle cells of smooth muscle. Although it rarely occurs in soft tissue, it is common in the viscera. It is the most common soft tissue sarcoma of the gastrointestinal tract and uterus. The median age of patients is 60 years. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1865)
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
