[Adverse effects of double-hit combining ISS-Ⅲ stage and 1q gain or del (17p) on prognosis of patients with newly diagnosed multiple myeloma].
Objective: To evaluate the prognostic significance of combining ISS-Ⅲ and high risk cytogenetic abnormalities [HRCAs, including 1q gain/amplification and del (17p) ] in patients with newly-diagnosed multiple myeloma (NDMM). Methods: The clinical characteristics and relevant variables were retrospectively analyzed in a total of 270 NDMM patients diagnosed between November 2009 and May 2018. ISS-Ⅲ stage and HRCAs [detected by FISH, including 1q gain/amplification and del (17p) ] were defined as risk factors (hit). ⋯ Analogous results were obtained when different combinations of ISS stages and HRCAs were analyzed. Conclusion: These results suggest a potential but rather important role of combining multiple (e.g. double or triple) adverse factors determined via the routine ISS staging and FISH detection of cytogenetic abnormalities in risk stratification and prognostic prediction, which might be helpful to identify high risk patients more precisely at diagnosis. It also raised a possibility that a small group of ISS-Ⅲ patients carrying both 1q gain/amplification and del (17p) might represent an "extremely-high risk" subset of MM.
