Our findings suggested that CDKN2A/B deletions were associated with poor prognosis independently in both adult and childhood ALL patients. Inclusion of CDKN2A/B status may further improve the risk stratification of ALL patients. Key Messages Although numerous studies have explored the prognostic sig …

Among the equivocal biopsies, four showed homozygous and one showed hemizygous p16/CDKN2A deletion. Age over 60 years, asbestos exposure and p16/ CDKN2A deletion were associated with a worse prognosis. sarcoma patients reveals CDKN2A deletion as a biomarker for poor prognosis Nam Q. Bui 1* ,Joanna Przybyl 2 ,Sally E. Trabucco 3 ,Garrett Frampton 3 ,Trevor Hastie 4 ,Matt van de Rijn 2 2021-03-25 2006-03-15 CDKN2A deletion was associated with shorter overall survival in multivariate analysis corrected by age, IPI, transplant eligibility and GATA3 expression (adjusted HR =2.53; 95.006-6.3; p=0.048). These data suggest that CDKN2A deletions may be relevant for refining the prognosis of PTCL-NOS and their significance should be evaluated in prospective trials.

2016-06-01 · In our patient with hemizygous germline deletion of CDKN2A, it is prudent to extend melanoma screening given the increased risk of melanoma in families with CDKN2A alterations. CDKN2A/2B deletions can be detected in about 60% of pediatric and about 50% of adult T-ALL cases. Most deletions are within the resolution of the FISH technique. Genetic alterations of the 9p21 locus result in loss of regulation of the cell cycle which is critical to cancer development.

CDKN2A/B Homozygous Deletion in Cancer In CDKN2A/B wildtype cells, the CDKN2A gene synthesizes p16 (INK4A) and p14 (ARF). The p16 protein controls cell division by binding to CDK4/6. The CDKN2B gene is adjacent to CDKN2A and encodes the p15 (INK4B) protein, which also binds to and inactivates CDK4/6.

Among the equivocal biopsies, four showed homozygous and one showed hemizygous p16/CDKN2A deletion. Age over 60 years, asbestos exposure and p16/ CDKN2A deletion were associated with a worse prognosis.

Cdkn2a deletion

CDKN2A gene deletion is associated with an adverse prognosis in pediatric, adolescent, and adult patients with B-cell ALL (B-cell precursor or BCP-ALL) due to increased risk for relapse, poor response to therapy, lower overall survival, and/or higher incidence of concurrent deletion of other genes.

2017-06-19 · CDKN2A (or CDKN2A/B) homozygous deletion was identified as the sole driver alteration in 1.2% (16 of 1,322) RCC cases and also in other disease types, including 15.2% of salivary gland acinic cell tumors, 14.3% of bone giant-cell tumors, and 11.3% of bone chordomas (Table 1).

Human melanoma cell lines and tumor tissue from familial and sporadic melanomas have frequent, nonrandom chromosomal breaks and deletions on chromosome 9p21, a region that includes the tumor suppressor gene CDKN2A/p16 INK4A. Germ-line mutations within this gene have been observed in some familial melanoma kindreds, but somatic mutation in sporadic primary melanoma is infrequent. Thirty-nine

As expected, CDKN2A loss resulted in decreased p38/MAPK and NF-κB signature score in TCGA-SKCM cohort as compared with CDKN2A normal group (Figures 2A, B and 3F), indicating a negative association between CDKN2A deletion and p38/MAPK and NF-κB activation.
