    Description / Table of Contents: Summary Background: A slow growing indolent subcutaneous mass can be caused by a variety of benign and malignant soft tissue proliferations, however, it is often the first sign of soft tissue sarcomas. Radiological findings are unspecific and biopsy with histopathological analysis is needed. Method: Three female patients (age 9, 191/12 and 232/12 years) are presented with a slow growing subcutaneous mass, which was shown to be a malignant non-embryonal soft tissue sarcoma (alveolar soft part sarcoma). Results: Alveolar soft part sarcoma (ASPS) is a very rare malignancy. At diagnosis, 2 patients already had metastatic disease. One girl died before therapy, the other one suffers from slowly progressive pulmonary metastases 41/2 years after diagnosis, despite multi-modal treatment approaches. The third patient received polychemotherapy and local irradiation after complete tumor resection and is free of disease 8 months after diagnosis. Conclusion: ASPS is a rare slow growing malignancy with an extraordinary tendency to metastasize. The prognosis depends on wether the tumor is operable and whether there are metastases.
    Notes: Zusammenfassung Fragestellung: Langsam wachsende nicht schmerzhafte subkutane Knoten können durch unterschiedlichste gut- oder bösartige mesenchymale Proliferationen verursacht sein. Da sich hinter diesem Zeichen oft ein Malignom verbirgt und bildgebende Analysen nur selten den Weg zur Diagnose weisen, ist eine bioptische Klärung dringend erforderlich. Methode: Wir berichten über 3 Patientinnen (Alter 9, 191/12 und 231/6 Jahre) bei denen sich hinter einem langsam wachsenden subkutanen Knoten ein nicht embryonales Sarkom (Alveolar soft part sarcoma) verbarg. Ergebnisse: Das Alveolar soft part sarcoma (ASPS) ist ein ausgesprochenes seltenes Malignom. Zum Diagnosezeitpunkt lag bei 2 Patientinnen bereits eine Metastasierung vor. Eine Patientin verstarb noch vor Behandlungsbeginn. Bei der 2. sind Lungenmetastasen trotz multimodaler Therapie 41/2 Jahre nach Diagnosestellung langsam progredient. Die 3. Patientin erhielt nach Resektion eines lokalisierten ASPS am Oberarm postoperativ eine Polychemo- und lokale Strahlentherapie und ist 8 Monate nach der Diagnosestellung ohne Krankheitszeichen. Schlußfolgerung: Das ASPS ist ein langsam wachsender Tumor mit ausgeprägter Metastasierungstendenz. Die Prognose ist im wesentlichen von der Operabilität des Primärtumors und dem Vorliegen von Metastasen abhängig.

    Notes: Abstract  Between January 1983 and December 1997, 88 patients (36 female, 52 male, median age 37 years, range 19–57) with chronic myelogenous leukemia (CML) underwent allogeneic bone marrow transplantation (BMT) at the University Hospital of Vienna. Sixty patients were in chronic phase, 18 in accelerated phase, and ten in blast crisis. Marrow donors were HLA-identical siblings for 64 patients (BM 58, PBSC 6), 2-antigen-mismatched related donors (RD) for two, HLA-identical unrelated donors (URD) for 17, and 1-antigen-mismatched URD for five. The median time from diagnosis to BMT was 22 months (range 2–91), and 63 patients had received prior interferon (IFN)-alpha therapy, 46 (73%) for more than 6 months. Conditioning therapy consisted of cyclophosphamide (CY) and total body irradiation (TBI) in 71 patients and CY and busulfan (BU) in 16. One patient received etoposide and TBI. For graft-versus-host disease (GVHD) prophylaxis methotrexate (MTX) was given to 12 patients, MTX and cyclosporin A (CSA) to 67, CSA alone to four, and CSA and methylprednisolone to five. Durable engraftment was documented in 80 of 82 patients (98%). As of December 31, 1997, 52 patients (59%) were alive, 38 (58%) after sibling transplantation with a median observation time of 73 months and 14 (64%) after URD transplantation with a median observation time of 12 months. Probability of overall survival is 59%, for patients undergoing transplantation in chronic phase and 44% for patients undergoing transplantation in advanced stage CML. Probability of disease-free survival (DFS) after sibling and URD BMT is 55% and 59%, respectively. Ten patients (12%) experienced relapse of CML. Transplant-related mortality was 32% both after RD and after URD transplantation. Acute GVHD occurred in 53 of 80 evaluable patients (66%), consisting of grade III or IV in 14 patients (18%). Chronic GVHD developed in 40 of 63 eligible patients (63%), including extensive disease in 26 patients (41%). Thus, sibling and URD BMT offer high cure rates with acceptable toxicity to patients with CML.

    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.
