A consecutive series from two university hospitals of 50 patients with giant cell tumors was reviewed and histologically reconfirmed. The patients treated with curettage and acrylic cement were re-examined concerning function. Two of 14 cemented tumors had recurred but could be treated by additional cementation, so that no final failure of this method had occurred, compared to one of 19 radically resected and 12 of 22 with bone-graft after curettage. Joint function was normal in 11 and radiographic arthrosis of low grade was found in only two of 14 patients. It is concluded that this method gives a minimum of recurrence and a maximum of function. It is suggested that the old name of "giant cell sarcoma" should be reintroduced, bringing the tumor into the group of low-grade sarcomas where it belongs.

MR investigation was superior to the other imaging techniques in the evaluation of mycetoma and the assessment of therapy.

Early chest CT in neutropenic patients at risk for IPA is an important diagnostic and management tool and should be included in the investigative protocol even when chest radiographs are normal or non-specific.

Twenty rats with implanted liver tumor were studied. Following baseline angiography, the hepatic artery was embolized with Gelfoam powder or ethanol (n = 12) while the controls (n = 8) did not undergo embolization. Postmortem Microfil perfusion was performed in all livers. Filling of tumor lakes from the portal vein was seen more often in embolized animals than in controls, indicating the potential role of the portal venous system in the supply of dearterialized hepatic tumors. We discuss the possible clinical implication of our results.
