Impact of additional cytogenetic aberrations at diagnosis of chronic phase chronic myeloid leukemia.

ABSTRACT:

Objective

This study aimed to investigate the correlation between additional cytogenetic abnormalities (ACAs) at diagnosis and their clinical consequences in 337 Chinese chronic myeloid leukemia (CML) patients.

Design

Retrospective observational cohort study.

Methods

Response criteria were applied according to the European LeukemiaNet. Event-free survival (EFS) and progression-free survival (PFS) were analyzed. Independent predictors of PFS were assessed using Cox regression analysis.

Results

At diagnosis, ACAs were identified in 41 patients (12.2%), with 24 exhibiting high-risk ACAs. Patients with high-risk ACAs showed significantly lower molecular response rates than those with low-risk ACAs or non-ACAs. Furthermore, patients with high-risk ACAs demonstrated
