METHODS: We retrospectively analyzed 134 CLL patients with del(13q) treated with FCR from March 2004 to August 2014 in our institution. Around 85% of people with chronic lymphocytic leukemia (CLL) live for 5 or more years following diagnosis. Thirteen percent (n=17) patients died after FCR treatment, of which 8 had progressed and 9 had not progressed. In general, people with this take about 10 years or so to get to requiring treatment. The disease pathogenesis lies in molecular genetics, the most common alteration being the deletion in the long arm of chromosome 13, at position 14 (13q14) region. In CLL, the most common DNA mutation is a deletion in chromosome 13 [del(13q)]. Genes Chromosomes Cancer. 13q deletion 178(55) 11q deletion 58(18) trisomy 12 53(16) 17p deletion 23(7) 6q deletion 21(6) Dohner et al.

This significant 13q14 deletion contributes to CLL's pathogenesis and paves the way for CLL treatment, hence affecting the prognosis of the affected patients. Department of Veterans Affairs. Journal of Hematology & Oncology. ~Trisomy 12 is considered an intermediate risk chromosomal aberration and its impact on therapeutic choices is presently unknown. This iterates to the fact that patients should undergo testing for TP53 mutation in addition to standard FISH testing for Del(17p). In most cases of CLL, a change can be found in at least one of these chromosomes. The four most common chromosomal aberrations that are detected using "FISH" studies at diagnosis are: 1) Deletions on the long arm of chromosome 13 (del (13q14)) (present in 55%) 2) Deletions on the long arm of chromosome 11 (del (11q23)) (present in 18%) 3) Trisomy 12 .

It is not a mutation or genetic change in one gene, but rather am extra chromosome, which is the structure that holds your genetic material. In the Rai system, a person will have blood tests to check for cancer cells and determine how many white blood cells are in the blood and bone marrow. In the United States, the current 5-year survival rate for CLL is 87%. In Germany, the annual incidence in men is 7.4/100.000 and in women 4.8/100.000, and the median age of onset is between 70 and 75 years. These mutations do not impact choice of therapy at this time. We performed fluorescence in situ hybridization (FISH) studies with 13q locus-specific LSI-D13S25 and LSI-RB1 probes. It is rare for treatment to cure CLL, but it can successfully manage the condition.
