    Notes: Abstract Between February 1982 and April 1995, 62 patients (37 male, 25 female) with acute myelogenous leukemia (AML) with a median age of 32 years (19–51 years) received allogeneic marrow grafts from an HLA-identical sibling (n=60) or an HLA-mismatched family member (n=2). At the time of transplant, 35 patients were in first complete remission (CR), five in second CR, eight were primary refractory, eight were in untreated relapse and six in refractory relapse. The FAB subtypes were as follows: M1 (n=17), M2 (n=13), M3 (n=6), M4 (n=19), M5 (n=6), M6 (n=1). For conditioning most patients were given total body irradiation combined with cyclophosphamide (CY,n=50) or CY and busulfan (n=9). For graft-versus-host disease prophylaxis patients received cyclosporin A (CSA) and methotrexate (MTX) (n=32), MTX alone (n=12), CSA and methylprednisone (n=5), or CSA alone (n=13). As of April 1995, probability of leukemia-free survival projected at 10 years after BMT was 60% for patients transplanted in first CR compared with 10% for patients transplanted beyond first CR. Transplant-related mortality was 11% after BMT in first CR and 39% after BMT beyond first CR. Probability of relapse projected at 10 years after BMT is 32% for patients who received transplants in first CR and 81% for patients who received transplants beyond first CR. Thus, high-dose chemo/radiotherapy followed by allogeneic marrow infusion has a high curative potential for patients with AML who receive transplants in first CR and offers the chance of long-term disease-free survival for some patients with advanced disease.

    Notes: Summary  Stereotactic radiosurgery (RS) and surgery have proved to be effective treatment modalities for brain metastasis. We followed 133 patients whose treatment for intracranial disease was either RS or a single surgical resection at the University of Vienna from August 1992 through October 1996. All patients who received additional Whole Brain Radiotherapy were included. This was a retrospective, case-control study comparing these treatment modalities.  Sixty-seven patients were treated by RS and 66 patients were treated by microsurgery. The median size of the treated lesions for RS patients was 7800 mm3, and 12500 mm3 for microsurgery patients, respectively. The median dose delivered to the tumour margin for RS patients was 17 gray.  The median survival for patients after RS was 12 months, and 9 months for patients after microsurgery. This difference was not statistically significant (p=0.19). Comparison of local tumour control, defined as absence of regrowth of a treated lesion, showed that tumours following RS had a preferred local control rate (p〈0.05). Univariate and multivariate analysis showed that this fact was due to a greater response rate of “radioresistant” metastasis to RS (p〈0.005). Postradiosurgical complications included the onset of peritumoural oedema (n=5) and radiation necrosis (n=1). Two patients after microsurgery experienced local wound infection. One postoperative death occurred due to pulmonary embolism in this group.  On the basis of our data we conclude that RS and microsurgery combined with Whole Brain Radiotherapy are comparable modalities in treating single brain metastasis. Concerning morbidity and local tumour control, in particular in cases of “radioresistant” primary tumours, RS is superior. Therefore we advocate RS except for cases of large tumours (〉3 cm in maximum diameter) and for those with mass effect.
