“…Several investigations addressing this question have reported significant differences in univariate analyses, but when multivariate models have been used, taking into account other factors, such as age, gender, karyotype, white blood cell and platelet counts, Auer rods, bone marrow cellularity, degree of dysplasia, and percentage of myeloblasts, it has become evident that the FAB subtype is not an independent prognostic factor. 7,25,26,28,31,34,[39][40][41] Thus, our finding that morphologic subgroup did not significantly modify the survival curves for the different cytogenetic prognostic groups agrees well with the results of these previous investigations.…”

“…In favor of this conclusion is the relatively high median age (63 years), which exceeds what has been reported in previous studies addressing the prognostic impact of karyotype in AML. 6,9,10,12,[24][25][26][27][28][29][30][31][32][33][34][35][36] It should be stressed, however, that some AML in our region have not been cytogenetically characterized. This group, the size of which may be close to 50%, 37 consists mainly of elderly patients, too frail for curative as well as palliative chemotherapy.…”

“…These differences may be related to the very small number of patients in some reports, but more importantly due to the cytogenetic heterogeneity of the cases. In most studies, cases with isolated trisomy 8 were analysed together with patients who showed trisomy 8 and additional other anomalies (Larson et al, 1983;FIWCL, 1984;Bloomfield & de la Chapelle, 1987;Samuels et al, 1988;Fenaux et al, 1989;Stasi et al, 1993;Joventino et al, 1995) (Table III) whereas cases with trisomy 8 in combination with complex anomalies face the worst prognosis. So far only four studies have reported on survival data with þ8 as the sole anomaly (Yunis et al, 1984;Berger et al, 1987;Dastugue et al, 1995;Byrd et al, 1996) (Table IV).…”
