Some murine sarcoma virus (MSV)-transformed mouse 3T3 cells contain the MSV genome in the absence of infectious helper murine leukemia virus (MuLV) and MSV production. These cells, designated S+L- (sarcoma positive, leukemia negative), were analyzed for the presence of a possible MSV-determined membrane antigen by the mixed hemadsorption test and in vitro lymphocyte cytotoxicity assay. Two diff...

Background: The effect of race and ethnicity on some kind of malignant bone tumors including Ewing sarcomahas been proven in different studies. In order to evaluate the latter, national cancer registries may help to increaseunderstanding about potential cancer causes, prevention and control strategies, and apply these findings to controlhealth problems among populations with s...

For centuries, Aloe Vera has been used by many different cultures. The ancient Greeks, the Romans, the Babylonians, Indians and the Chinese have all used Aloe Vera as a medicinal plant. One of the common experimental cancer models is sarcoma-180. When Aloe was administered to mice bearing S-180 tumors, the tumor growth was inhibited. Aloe vera is a dietary supplement and not a regulated drug. T...

  Extra-skeletal Ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal Ewing’s sarcoma. The usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. Extra-skeletal Ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. The cytological features...

Sarcomas are rare tumors with devastating clinical consequences, often affecting children as well as adults. Brain metastasis in sarcoma is frequently preceded by lung metastasis. Common offenders include Ewing sarcoma, osteosarcoma and leiomyosarcoma. Although our understanding of sarcoma metastasis remains limited, several cellular factors and signaling pathways appear to play regulatory role...

s—Invited Speakers The past 25 years of EORTC soft tissue and bone sarcoma group A. VAN OOSTEROM (Department of Oncology, U.Z. Gasthuisberg, KU Leuven, Leuven) Preliminary meetings in April—to June 1976—between founding members led to the full development of a protocol in which CyVADic was compared with CyV-Adic in advanced soft tissue sarcoma. This protocol was approved by the EORTC Protocol R...

Alveolar soft part sarcoma is an extremely rare type of soft tissue malignancy, manifests in a variety of locations. We report a case of a 28-year-old Chinese woman presented with alveolar soft part sarcoma. To the best of our knowledge, this study is the first to report a case of alveolar soft part sarcoma with primary location in the pararectal space of the pelvic cavity. Histopathologically,...
