Abstract
We studied 79 patients with AML-MRC or RAEB-T, who were later reclassified according to the WHO classification. Marrow slides were examined cytomorphologically with regard to dysplasia. Patients were followed up until March 2020. Thirty-one patients underwent allogeneic stem cell transplantation (median survival (ms) 16 months), 14 were treated with induction chemotherapy (ms 8.4 months), 18 received hypomethylating agents (ms 9.2 months), 16 received low dose chemotherapy or best supportive care (ms 2.4 months). Only 30.4 % fulfilled the morphologic WHO criteria. 46.8 % were classified as AML-MRC by an antecedent MDS, 54.4 % of the pts were classified by MDS-related chromosomal abnormalities. 5 % did not fulfill any of the criteria and were entered based on 20-29 % medullary blasts. There was no difference in ms between pts presenting with > 50 % dysplasia as compared to pts with dysplasia between 10 % and 50 % (ms 9.1 vs 9.9 months, p = n.s.) or for pts with antecedent MDS (ms 9.1 vs 8.9 months, p = n.s.). Myelodysplasia-related cytogenetic abnormalities were associated with a worse outcome (ms 8.1 vs 13.5 months, p = 0.026). AML-MRC in its current definition is a heterogenous entity. Dysplasia of ≥ 50 % in ≥ two lineages is not helpful for diagnostics and prognostication and therefore should be deleted in future classifications. We recommend utilizing the WHO guidelines for defining dysplasia (10 % or greater in ≥ 1 of the three myeloid cell lines) assisting in establishing the diagnosis of MDS.

Abstract
The formation of 19-norsteroids by demethylation of endogenous steroids in stored urine samples was observed. Suspicious urine samples (i.e. containing trace amounts of 19-norandrosterone and 19-noretiocholanolone) were selected and spiked with deuterated analogues of androsterone and etiocholanolone at concentrations corresponding to high endogenous levels (4 microg/mL). After incubation, respective 19-norsteroids (19-norandrosterone-d4 and 19-noretiocholanolone-d5) were identified in these samples by high-resolution mass spectrometry. The transformation of the 5 beta-isomer (etiocholanolone) yields about three-fold higher concentrations, compared to the 5 alpha-isomer. A significant temperature dependence was observed by comparison of reaction kinetics at room temperature (23+/-2 degrees C) and 37 degrees C. Concentrations of 19-norandrosterone-d4 and 19-noretiocholanolone-d5, respectively, were 2.7 and 3.6 times higher at elevated temperature. The conversion of androsterone-d4 to 19-norandrosterone-d4 did not exceed a relative amount of 0.1%. Incubation of the urine samples with androsterone-d4-glucuronide led to the production of 19-norandrosterone-d4-glucuronoide. A partial stabilization was observed after addition of metabolic inhibitors (e.g. EDTA). The application of the incubation experiments described may contribute to the clarification of adverse analytical findings regarding low levels of 19-norsteroid metabolites.
