Sumario: | OBJECTIVE: To evaluate the response of oral melphalan plus high-dose dexamethasone (MDex) for patients with primary light chain amyloidosis (pAL). METHODS: Clinical data, hematological and organ responses, and survival of 76 patients with pAL who had received MDex from January 2009 to July 2017 were retrospectively analyzed. RESULTS: Of 76 patients (47 males and 29 females with the median age of 56 [range, 20–74] years old), 19.70% patients were defined as Mayo 2004 stage 3, involvement of more than or two organs was presented in 65 (85.53%) patients. Among 60 response evaluable patients, overall hematological response was 48.33% with complete response of 20.00% and very good partial response of 20.00%, respectively. The median time to the hematological response was 5 (range, 1–15) months. 36.67% patients achieved organ response. After the median follow up of 23(range, 1–113) months for surviving patients, median progression-free survival (PFS) and overall survival (OS) were 34 and 43 months, respectively. In a three months landmark analysis, the median rates of PFS and OS were 46 and 65 months, respectively. The median OS rates of patients with Mayo 2004 stage 3 and non Mayo 2004 stage 3 were 5 and 65 months (P=0.001), respectively. CONCLUSION: MDex was an effective treatment for patients with early stage pAL, but was not suitable for those with severe cardiac involvement. |
