Non-treatment-related chronic myeloid leukemia as a second malignancy.
The characteristics of the very rare non-treatment-related chronic myeloid leukemia (nTr-CML) cases have never before been analyzed. The literature up to December 2002 was screened using the Medline database to identify cases of Tr-CML and nTr-CML. We considered five cases with nTr-CML identified among 270 newly diagnosed CML at our Department. Our report thus considers nine cases with nTr-CML compared to 77 affected by Tr-CML as a secondary neoplasm. The median age at the appearance of the first tumor was higher in nTr-CML patients compared to that of the Tr-CML group (P<0.0001). The median age at CML diagnosis was significantly higher in the nTr-CML than in the Tr-CML group (P<0.0001). The proportion of hematological malignancies as first tumor type was not different in the two groups (44% in nTr-CML versus 56% in Tr-CML). Our study underlines that nTr-CML as a second malignancy is a rare entity associated with elderly age.
