Abstract
Prognostic significance of high-risk cytogenetic abnormalities in Multiple Myeloma in Colombia is unknown. In a retrospective cohort study of 135 newly, diagnostic Multiple Myeloma we found incidence of high-risk cytogenetic abnormalities was 30.3%. The hazard ratio (HR) for disease progression or death compared high-risk cytogenetic group vs. control was 1.22, (95% CI, 0.73-2.05) (P = .2), and The HR for death for the group of high-risk cytogenetic abnormalities was 2.17, (95% CI, 1.19-3.97). In the group of high-risk cytogenetic abnormalities, if the patient received VRD as induction treatment the median PFS were 41.2 months 95% CI [13.3-NA] and 33.9 months 95% CI [24.9-NA] for patients with different induction treatment (P = .56)
Conclusion
High-risk cytogenetically abnormalities were independent risk factor for OS but not PFS in this cohort of patients, and the incidence of del (17p) was slightly higher than the literature reports.
