OBJECTIVE: To analyze the factors affecting the long-term survival of patients with chronic lymphocytic leukemia (CLL).
METHODS: The clinical data of 101 newly diagnosed CLL patients from January 2010 to January 2021 were retrospectively analyzed. Rai and Binet staging systems were used for clinical staging, and CLL-IPI was used for risk stratification of the patients.
RESULTS: There were 61 males and 40 females, the median age at diagnosis was 64 (28-84) years, the median PFS (progression-free survival) was 77（66-88） months, the 2-year and 5-year PFS rates were 85% and 64% respectively. The median OS (overall survival) was 108（103-112） months, the 5-year and 9-year OS rates were 74% and 46% respectively. Univariate analysis showed that high or very high risk of CLL-IPI, TP53 aberrations, del(17p), need for treatment and different treatment methods were the factors affecting OS (P<0.05); high or very high risk of CLL-IPI, TP53 aberrations, del(17p) and complex karyotype were associated with PFS (P<0.05). By X-tile analysis, it was found that the white blood cell count, the absolute neutrophil count, the hemoglobin level, and β2-microglobulin level were associated with OS (P<0.05); the white blood cell count, the absolute lymphocytes count, the hemoglobin level, the platelet count, and the lactate dehydrogenase level were associated with PFS（P＜0.05）.
CONCLUSION: The high or very high risk of CLL-IPI, TP53 aberrations, del(17p), need for treatment and different treatment methods are the factors affecting the OS of CLL patients, and high or very high risk of CLL-IPI, TP53 aberrations, del(17p) and complex karyotype are the factors affecting the PFS of CLL patients.
