Data set name: GSE1577


Original data set (GSE1577)
Data set for Orange
Brief description:
The malignant cells in T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL) are morphologically indistinguishable, and they share the expression of common cell surface antigens and cytogenetic characteristics. However, despite these similarities, differences in the clinical behavior of T-ALL and T-LL are observed. The model was built with global gene expression profiles of malignant T-cell precursors of T-ALL and T-LL.

Platform: Affymetrix GeneChip Human Genome U133 Array Set HG-U133A

Diagnostic classes:
- T-cell lymphoblastic lymphoma (T-LL): 9 examples (47.4%)
- T-cell acute lymphoblastic leukemia (T-ALL): 10 examples (52.6%)
Number of genes: 15434
Number of samples: 19
Note: From the originally measured 22283 probe sets we removed genes that were not present (P) in at least one sample
Predictive accuracy with 10-fold cross validation (classifying using the best projection with eight attributes):
Classification accuracy: 95.00%
Area under curve (AUC): 1.000
