Relapse of malignant disease remains the major complication in patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) after hematopoietic cell transplantation (HCT) with reduced-intensity conditioning (RIC). In this study, we investigated the predictive value of disease-specific markers (DSMs), donor chimerism (DC) analysis of unsorted (UDC) or CD34+ sorted cells and Wilms' tumor gene 1 (WT1) expression. Eighty-eight patients with AML or MDS were monitored after allogenic HCT following 2 Gy total-body irradiation with (n=84) or without (n=4) fludarabine 3 × 30 mg/m2, followed by cyclosporin A and mycophenolate mofetil. DSMs were determined by fluorescence in situ hybridization (FISH) and WT1 expression by real-time polymerase chain reaction. Chimerism analysis was performed on unsorted or CD34+ sorted cells, by FISH or short tandem repeat polymerase chain reaction. Twenty-one (24%) patients relapsed within 4 months after HCT. UDC, CD34+ DC and WT1 expression were each significant predictors of relapse with sensitivities ranging from 53 to 79% and specificities of 82-91%. Relapse within 28 days was excluded almost entirely on the basis of WT1 expression combined with CD34+ DC kinetics. Monitoring of WT1 expression and CD34+ DC predict relapse of AML and MDS after RIC-HCT. [ABSTRACT FROM AUTHOR]

The cancellous bone of the skeleton usually shows striking alterations when metastatic carcinoma has involved the bone marrow. These changes, termed carcinomatous osteodysplasia (COD), have been analyzed in 1164 iliac crest biopsies of unselected patients with a variety of primary tumours. Semithin (3 μ) sections of undecalcified biopsies embedded in methacrylate were examined for foreign cells. Metastases were found in 462 of the 1164 biopsies and 91% of these, as well as 17% of the negative biopsies, showed some degree of COD. Osteodysplasia was more frequent in biopsies of patients with signs of systemic spread than in those without. COD includes a variable, local increase in active osteoblasts and osteoclasts, in blood vessels and in other stromal tissues. The incidence of COD was higher in the adenomatous and scirrhous metastases than in the other histological varieties. COD was subdivided into primarily osteolytic, osteosclerotic, and mixed types, and five different forms of bone resorption and formation were identified. These forms showed a characteristic association with the degree of mesenchymal activation on the one hand and the structural type of the metastases on the other, and correlated with certain cytological characteristics of the neoplastic cells. We conclude that COD is a significant consequence of the biological activities of metastatic cancer and it is readily accesible for observation by bone biopsy. The morphological classification of COD proposed in this study provides a basis for further investigation. [ABSTRACT FROM AUTHOR]

Bone marrow biopsy of the iliac crest was performed on 268 patients (124♂; 144♀). Of these patients 206 had haematological systemic disorders (HSD) or carcinoma and suspected bone involvement, which was confirmed by biopsy on 66 patients. Bone biopsy was performed not longer than 3 weeks after X-ray examination and bone scintigraphy which, combined, had already raised the suspicion of skeletal involvement in 55% of the 66 patients with skeletal involvement diagnosed by biopsy. Additional quantitative evaluation of the bone scans using bone to soft tissue ratios was able to increase the overall accuracy to 67% in that group. Additional quantitative assessment of the scan yielded considerably more effective bone scintigraphy, particularly in cases with visually normal patterns. Available equipment should therefore be used in scintigraphic bone imaging on a routine basis. It was shown that the various methods of examination, i.e. X-ray, biopsy and scintigraphy with both visual and quantitative evaluation provide their own individual values for the final diagnosis. Therefore, if one of the methods shows a negative result, bone involvement is not excluded and the others should be used for confirmation. [ABSTRACT FROM AUTHOR]
