摘要

Multiple Myeloma (MM) is the second most common hematological cancer, several cytogenetics abnormalities such as t(4;14), del (17p), and t(14;16) were identified as a high-risk for survival, in Latin America, we have very little data on cytogenetic alterations in MM. This study describes the incidence of high-risk cytogenetically abnormalities in a Colombian population and prognostic significance.In a retrospective cohort of new diagnostic Multiple Myeloma between 2016 and 2020, we identified a high-risk cytogenetically abnormalities t(4;14), t(14;16), and 17p deletions by FISH techniques and described incidence. We followed patients until progression or death and comparing progression free survival (PFS) and overall survival (OS), according with high- risk cytogenetically features.We included 135 newly diagnosed MM patients, the incidence of high-risk cytogenetically abnormalities were 30.3%, with 17.1% of 17p deletions, 14.1% of t(4;14) and 2.25% of t(14;16). According to the high risk cytogenetically abnormalities, the median PFS for the group of no abnormalities were 50.2 months 95% CI [25.2-62.4] and for the group of high-risk cytogenetic abnormalities 33.9 months 95% CI [23.6-NA] (P = .2). For OS the median were 76.9 months, 95% CI [67.5-NA] and 42.7 months 95% CI [33.3-NA], respectively (P = .009).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. MICROABSTRACT: 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).
