Association of Telomere Length of Peripheral Blood Leukocytes With Hematopoietic Relapse, Malignant Transformation, and Survival in Severe Aplastic Anemia
Open accessAbstract
CONTEXT: Critically short telomeres produce apoptosis, cell senescence, and chromosomal instability in tissue culture and animal models. Variations in telomere length have been reported in severe aplastic anemia but their clinical significance is unknown. OBJECTIVE: To investigate the relationship between telomere length and clinical outcomes in severe aplastic anemia. DESIGN, SETTING, AND PATIENTS: Single institution analysis of 183 patients with severe aplastic anemia who were treated in sequential prospective protocols at the National Institutes of Health from 2000 to 2008. The pretreatment leukocyte age-adjusted telomere length of patients with severe aplastic anemia consecutively enrolled in immunosuppression protocols with antithymocyte globulin plus cyclosporine for correlation with clinical outcomes were analyzed. MAIN OUTCOME MEASURES: Hematologic response, relapse, clonal evolution, and survival. RESULTS: There was no relationship between hematologic response and telomere length with response rates of 56.5% of 46 patients in the first, 54.3% of 46 in the second, 60% of 45 in the third, and 56.5% of 46 in the fourth quartiles. Multivariate analysis demonstrated that telomere length was associated with relapse, clonal evolution, and mortality. Evaluated as a continuous variable, telomere length inversely correlated with the probability of hematologic relapse (hazard ratio [HR], 0.16; 95% confidence interval [CI], 0.03-0.69; P = .01). The probability of clonal evolution was higher in patients in the first quartile (24.5%; 95% CI, 8.7%-37.5%) than in quartiles 2 through 4 (8.4%; 95% CI, 3.2%-13.3%; P = .009), and evolution to monosomy 7 or complex cytogenetics was more common in the first quartile (18.8%; 95% CI, 3.5%-31.6%) [corrected] than in quartiles 2 through 4 (4.5%; 95% CI, 0.5%-8.2%; P = .002) [corrected]. Survival between these 2 groups differed, with 66% (95% CI, 52.9%-82.5%) surviving 6 years in the first quartile compared with 83.8% (95% CI, 77.3%-90.9%) in quartiles 2 through 4 (P = .008). CONCLUSION: In a cohort of patients with severe aplastic anemia receiving immunosuppressive therapy, telomere length was unrelated to response but was associated with risk of relapse, clonal evolution, and overall survival.

Patients with aplastic anaemia and shorter telomeres at diagnosis show more severe disease, poorer response to treatment, increased risk of relapse and MDS, and lower survival.
“Patients with shorter telomeres at diagnosis show a more severe disease, a poorer response to treatments, an increased risk of relapse and development of myelodysplastic syndrome (MDS; see below) and a lower survival rate75,80,81.”
From Telomere dysfunction in ageing and age-related diseases (2022) · cites this paper as [80]
The Results (Response and relapse according to telomere length; Clonal evolution and survival according to telomere length) associate shorter pretreatment telomeres with relapse, clonal evolution and lower survival. They do not establish more severe disease at diagnosis, and explicitly report no correlation between telomere length and response to initial immunosuppressive treatment. The paper reports clonal evolution, including changes associated with myelodysplasia, rather than a separate MDS risk estimate. (LLM, conf=0.91)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
