Breakpoint zone of bcr in chronic myelogenous leukemia does not correlate with disease phase or prognosis. 1988

D Przepiorka

Pittsburgh Cancer Institute, Pennsylvania.

The presence of a zone 4 rearrangement in the bcr of two chronic myelogenous leukemia (CML) cell lines and 25 CML patients was investigated by hybridization of HindIII-EcoRI double-digested DNA with the homologous HindIII-BglII breakpoint cluster region (bcr) probe. A rearrangement in zone 4 was found in the EM2 cell line and in 11 of the 25 patients. The presence of a zone 4 rearrangement was not associated with phase of disease, clinical evidence of acceleration, or pathologic evidence of acceleration. The difference between the actuarial duration of chronic phase for patients without (33 months) and with (22 months) a zone 4 rearrangement was not significant. A breakpoint in zone 4 of the bcr in patients with CML does not appear to be a determinant of prognosis.

UI	MeSH Term	Description	Entries
D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
