What does positive for trisomy 12 mean with CLL?

What does positive for trisomy 12 mean with CLL?

Trisomy 12 is seen in approximately 20% of cases of chronic lymphocytic leukemia (CLL) and is associated with poor prognosis, whereas del(13q14) is seen in approximately 50% of cases and is also associated with a favorable prognosis. Other deletions seen in CLL include those of 11q and 17p.

What is the life expectancy of CLL patients?

The prognosis of patients with CLL varies widely at diagnosis. Some patients die rapidly, within 2-3 years of diagnosis, because of complications from CLL. Most patients live 5-10 years, with an initial course that is relatively benign but followed by a terminal, progressive, and resistant phase lasting 1-2 years.

How common is trisomy 12?

Trisomy 12 is the second most frequent aberration detected by fluorescence in situ hybridization at the time of diagnosis (10–25%), and it confers an intermediate prognostic risk, with a median time to first treatment of 33 months and a median overall survival of 114 months.

Which of the following is considered a favorable prognostic factor in CLL?

Lymphocyte doubling time is the time it takes for the lymphocyte count to double. A lymphocyte doubling time of more than 6 months is a more favourable prognostic factor.

Is CLL considered a terminal illness?

Chronic lymphocytic leukemia (CLL) can rarely be cured. Still, most people live with the disease for many years. Some people with CLL can live for years without treatment, but over time, most will need to be treated.

Is CLL a death sentence?

CLL is not an imminent death sentence, especially now. A significant chunk of us will never need treatment and even more of die with the disease, not from it.

What happens when CLL mutates?

Approximately 30%–40% of CLL patients with 11q22. 3 deletion and progressive disease have a dysfunctional (missense or a nonsense) mutation in the remaining ATM allele, resulting in more aggressive disease, poorer treatment responses, and shorter overall survival similar to that of CLL patients with dysfunctional p53.

How do you know if CLL is getting worse?

Unexplained weight loss of more than 10 percent of your body weight over the course of 6 months or so could mean your CLL is progressing. This means that you’re losing weight when you’re not trying to diet.

Does CLL metastasize?

Bone metastasis in CLL/SLL is very rare, generally osteolytic, and affects less than 5% of CLL patients [6–9].

Can you live with monosomy?

In most cases, embryos with monosomy of the autosomes or sex chromosomes are not viable. Some individuals with monosomy of the sex chromosomes (45XO genotype) can survive, however (Figure 6). Such individuals, who are said to have Turner’s syndrome, exhibit a female phenotype, but the gonads are sterile.

Is CLL always fatal?

Chronic lymphocytic leukemia (CLL) can rarely be cured. Still, most people live with the disease for many years. Some people with CLL can live for years without treatment, but over time, most will need to be treated. Most people with CLL are treated on and off for years.

Can a person live 20 years with CLL?

CLL has a very high incidence rate in people older than 60 years. CLL affects men more than women. If the disease has affected the B cells, the person’s life expectancy can range from 10 to 20 years.

What is the most common cause of death in CLL?

The cause of death could be accurately determined in 183 (82%) of these patients. The cause of death was due to CLL in 135 (74%), including 84 (46%) CLL progressions, 14 (8%) infections, and 37 (20%) other cancers….Conclusions.

What are the final stages of CLL?

When the disease moves into the later stages, CLL cells crowd out the healthy cells in the bone marrow, which could lead to problems such as anemia, low platelets, and an enlarged liver and spleen.
