RESUMEN
Objective:To analyze relationship between 13q14 deletion and prognosis in initial-treatment patients with multiple myeloma (MM).Methods:The follow-up data of 121 patients with newly diagnosed MM admitted to the First People's Hospital of Xiangtan City from January 2012 to December 2016 were collected and divided into deletion group ( n=39) and non deletion group ( n=82) according to the deletion of 13q14.The prognosis situations were compared among patients with different 13q14 deletion. Univariate analysis was performed for 3-year overall survival (OS) and progression free survival (PFS) in patients with MM. Results:As of the follow-up time, the 3-year OS rate, 3-year OS, 3-year PFS rate, 3-year PFS and median PFS were 71.90%(87/121), 5.8-36 months, 47.93%(58/121), 2.3-36 months and 34.8 months, respectively. The age, hypoproteinemia, high lactic dehydrogenase (LDH) and 13q14 deletion were independent influencing factors of OS ( P<0.05). The age, high LDH and 13q14 deletion were independent influencing factors of PFS ( P<0.05). The 3-year OS rate and 3-year PFS rate in 13q14 deletion group were 61.54%(24/39) and 25.64%(10/39), lower than those in non-deletion group ( P<0.05). Conclusions:The short-term prognosis is poor in initial-treatment MM patients with 13q14 deletion. Conducting risk stratified treatment for patients based on common influencing factors of OS and PFS is conducive to improving their prognosis.
