PURPOSE Soft tissue sarcoma of the hand is rare, and one of the most common histological diagnosis is synovial sarcoma. We report the clinical outcomes of patients with synovial sarcoma of the hand and discuss treatment strategies. METHODS We reviewed five patients with synovial sarcoma of the hand treated at our institutions from 1983 to 2013. The mean patient age at the time of diagnosis wa...
We identified eight patients of 2900 with a primary malignant bone tumour who had coexisting neurofibromatosis type 1. This was a much higher incidence than would be expected by chance. The patients had a mean age of 22.4 years (9 to 54): five were male. Two patients subsequently developed a second bone sarcoma, one of which was radiation induced. Four of the primary tumours were osteosarcomas,...
a 14 years old girl, with documented ewing's sarcoma, was treated by both chemotherapy and surgery. an initial bone scan (tc-99m-mi)i*) did not reveal a renal lesion. however, following therapeutic irradiation, there was retention of the bone imaging agent in a portion of the kidney that had been included in the radiation field. this reflected the effects of radiation related parenchymal altera...
Rhabdomyosarcoma is a malignant neoplasm and the most common soft tissue sarcoma in children. The current frontline treatment for rhabdomyosarcoma is a multi-modal approach, comprising chemotherapy, surgical resection, and/or radiation therapy. Radiation therapy during odontogenesis can lead to delayed sequel such as hypodontia, microdontia, and dwarfed teeth with underdeveloped roots. This cas...
Cell-mediated immunity to Moloney murine leukemia virus (M-MuLV) and to tumor-associated surface antigens of leukemia cells induced by the virus was studied with an in vitro migration inhibition factor assay. Spleen cells of C57BL/6N mice at Day 14 following inoculation with Moloney murine sarcoma virus, produced migration inhibition factor in response to M-MuLV. The Moloney murine sarcoma viru...
Giant cell tumour (GCT) of bone is a locally aggressive benign tumour. It can, however, undergo dedifferentiation, either de novo or secondarily after local recurrence or radiation. Whether spontaneously occurring or induced by previous irradiation, this malignant transformation is typically defined as a high-grade anaplastic sarcoma devoid of giant cells. Dedifferentiation of GCT into low-grad...
Clear cell sarcoma is an aggressive soft tissue sarcoma and highly resistant to conventional chemotherapy and radiation therapy. This devastating disease is defined by EWSR1-ATF1 fusion gene resulting from chromosomal translocation t(12;22)(q13;q12) and characterized by melanocytic differentiation. A marine-derived antineoplastic agent, trabectedin, inhibits the growth of myxoid liposarcoma and...
BACKGROUND Apoptosis is a major mode of hematological tumor death after radiation. Early detection of apoptosis may be beneficial for cancer adaptive treatment. 99mTc-HYNIC-annexinV has been reported as a promising agent for in vivo apoptosis imaging. The purpose of this study is to evaluate the feasibility of in vivo99mTc-HYNIC-annexinV imaging of radiation- induced apoptosis, and to investiga...
A 14 years old girl, with documented Ewing's sarcoma, was treated by both chemotherapy and surgery. An initial bone scan (TC-99m-MI)I*) did not reveal a renal lesion. However, following therapeutic irradiation, there was retention of the bone imaging agent in a portion of the kidney that had been included in the radiation field. This reflected the effects of radiation related parenchymal ...
