A novel approach to soft tissue sarcoma therapy:targeting tumor hypoxia
نویسندگان
چکیده
Single agent doxorubin was introduced for the treatment of soft tissue sarcoma beginning in the 1970’s. Since then, combination therapies with an anthracylcine backbone are commonly used, but have failed to show significant improvements in survival compared to single agent doxorubicin. TH-302, a pro-drug activated by tumor hypoxia, is a promising new therapeutic agent for soft tissue sarcomas. This novel agent has been shown to be safe in phase I and II clinical trials with minimal added toxicity. The data has suggested that TH-302 in addition to doxorubicin may have promising activity when compared to traditional combination therapy. A phase 3 study comparing TH-302 in addition to doxorubicin against doxorubicin alone has completed accrual. An improvement in outcomes would be proof of principal that targeting tumor hypoxia is an effective strategy for the treatment of soft tissue sarcoma.

Clear cell sarcoma of the hand: a case of malignant melanoma of soft parts
A case is reported with clear cell sarcoma (CCS) of the hand. Early diagnosis of clear cell sarcoma is always difficult due to its slow growing nature, benign clinical appearance, lack of pigmentation in most cases, and relatively young age of patients which make it to clinically appear as a benign soft tissue tumor. We report a case of clear cell sarcoma of hand in a 56 year old male with a no...

Multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. Herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. There was no family history and hereditary syndrome. The genetic analysis was completely normal. To best of our knowledge, t...
متن کاملPrimary Stromal Sarcoma of Breast: A Rare Entity
Primary soft tissue sarcomas of the breast constitute less than 5% of all soft tissue sarcomas and less than 1% of malignant breast cancers. The rarity of this tumor limits most studies to small retrospective case reviews and case reports. Primary breast sarcomas are locally aggressive tumors as evidenced by the high rate of local recurrence when excisional surgery is performed. A contemporary ...

Although rare, synovial sarcoma is the most common malignant non-rhabdomyosarcomatous soft tissue sarcoma in children and adolescents. Synovial sarcoma typically involves the soft tissues of the extremities, especially near large joints, but it can occur anywhere in the body in locations far from joint spaces. Although this tumor typically affects adults in their fourth decade of life, nearly h...
