    Objective: To investigate the prognostic value of translocation t(11;14) in newly-diagnosed primary light-chain (AL) amyloidosis patients treated with bortezomib-based regimen. Method: Clinical information of newly-diagnosed AL amyloidosis patients in Peking Union Medical College Hospital who had baseline t(11;14) data and accepted bortezomib-combined therapies from September, 2015 to September, 2021 was collected. The relationships between t(11;14) status and baseline characteristics, hematological response, organ response and prognosis were analyzed. Results: A total of 152 patients were included, aged (59.5±9.1) years and 93 cases were male (61.2%). Forty-six patients carried t(11;14) (30.3%). There was no statistical difference in the proportion of organ involved, distribution of Mayo 2004 and 2012 stages and laboratory indexes between patients with and without t(11;14) (all P>0.05). For hematological response, the difference in the rates of ≥very good partial response (VGPR) between those with t(11;14) and without after the first cycle [28.2%(11/39) vs 37.4%(34/91), P>0.05] was not statistically significant. After 3 cycles, the difference in the rates of ≥VGPR between two groups was not statistically significant [35.9%(14/39) vs 51.1%(46/90), P>0.05]. The difference in the ratio of the best hematological response reaching ≥VGPR between two groups during the first-line treatment was not statistically significant [52.2%(24/46) vs 64.2%(68/106), P>0.05]. But patients with t(11;14) had lower cardiac response rate at 3 months [15.2%(5/33) vs 34.6%(28/81), P=0.038] and 6 months [19.4%(6/31) vs 50.6%(42/83),P=0.003] than those without, but the difference in cardiac response rates at 12 months was not statistically significant [41.7%(10/24) vs 53.5%(38/71),P>0.05]. For survival, the differences in overall survival (not reached vs 50.1 months, P>0.05) and hematological event-free survival (36.2 months vs 39.9 months, P>0.05) between patients carrying t(11;14) and those without were not statistically significant. Conclusion: Patients with t(11;14) had lower cardiac response rate than those without, but their hematological response and survival are not significantly different from those free from t(11;14).
