Prognostic significance of SETBP1 mutations in myelodysplastic syndromes, chronic myelomonocytic leukemia, and chronic neutrophilic leukemia: A meta-analysis.

ABSTRACT:

Objectives

This meta-analysis investigates the prognostic effect of SET binding protein 1 (SETBP1) mutations in patients with myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), or chronic neutrophilic leukemia (CNL).

Methods

Eligible studies from Pubmed, Embase, and Web of Science were searched from database inception through April 2016. Hazard ratios (HRs) and 95% confidence interval (CI) of overall survival (OS) were pooled to calculate the prognostic significance of SETBP1 mutation in patients.

Results

A total of 12 studies with 2321 patients were included in this meta-analysis; 4 studies for MDS, 5 studies for CMML, and 3 studies for CNL. Pooled results suggested that MDS and CMML patients with SETBP1 mutations had a significantly poorer prognosis when compared with patients with wild-type SETBP1 (MDS: HR = 1.808, 95% CI (1.218-2.685), P = 0.001; CMML: HR = 2.223, 95% CI (1.493-3.308), P<0.001). SETBP1 mutations in CNL patients however, showed no significant effect on the overall survival (HR = 1.773, 95% CI (0.877-3.582), P = 0.111). The Begg's and Egger's tests did not show significant publication bias in any groups.

Conclusions

Current evidence shows that SETBP1 mutation is associated with a poor prognosis in patients with MDS and CMML, but not in patients with CNL.

Project description:Prior studies have investigated patients' characteristics, treatments, and outcomes for older adults with myelodysplastic syndromes, but most failed to distinguish chronic myelomonocytic leukemia. Recognizing potentially important differences between the diseases, we undertook a population-based comparison of baseline characteristics, treatments, and outcomes between older adults with chronic myelomonocytic leukemia and myelodysplastic syndromes. The patients' data were obtained from Surveillance Epidemiology and End Results registry data from 2001-2005, linked to Medicare claims. Baseline characteristics, treatment (red blood cell transfusions, hematopoietic growth factors, hypomethylating agents, chemotherapy or transplantation), progression to acute myeloid leukemia, and overall survival were compared using bivariate techniques. Multivariate logistic regression estimated differences in treatments received. Cox proportional hazard models estimated the effects of chronic myelomonocytic leukemia relative to myelodysplastic syndromes on progression-free survival. A larger proportion of patients with chronic myelomonocytic leukemia (n=792), compared to patients with myelodysplastic syndromes (n=7,385), failed to receive any treatment (25% versus 15%; P<0.0001), or only received red blood cell transfusions (19.8% versus 16.7%; P=0.037). A larger percentage of patients with chronic myelomonocytic leukemia progressed to acute myeloid leukemia (42.6% versus 15.5%, respectively; P<0.0001), with shorter time to progression. Chronic myelomonocytic leukemia patients had a shorter median survival (13.3 versus 23.3 months; P<0.0001) and lower 3-year survival rate (19% versus 36%; P<0.0001). Adjusted estimates, controlling for baseline characteristics and selected treatments, indicate that chronic myelomonocytic leukemia was associated with an increased risk of progression to acute myeloid leukemia or death (HR 2.22; P<0.0001), compared to myelodysplastic syndromes. In conclusion, chronic myelomonocytic leukemia is less frequently treated in older adults and is associated with worse outcomes, even after controlling for the patients' baseline characteristics and selected treatments. Our data suggest the need for continued evaluation of the biological differences between these diseases and clinical trials targeting chronic myelomonocytic leukemia.
