ABSTRACT

Objective@#To evaluate the clinical characteristics and outcomes of very high risk patients with primary immunoglobulin light-chain amyloidosis (pAL) at a single center in China.@*Method@#Clinical data, treatment and outcome of 205 pAL patients in Peking Union Medical College Hospital from January 2009 to February 2016 were retrospectively analyzed. A 'very high risk’ group includes patients with Mayo 2004 stage Ⅲb and Mayo 2012 stage 4.@*Results@#Of 205 patients, 34 (16.6%) were defined as very high risk pAL patients. The median age at diagnosis was 57 (20-84) years, and 22 patients (64.7%) were male. All 34 patients were diagnosed with cardiac involvement, multi-organ involvement was observed in 15 patients (44.1%) , and 27 (81.8%) had New York Heart Association Class Ⅲ or Ⅳ. Median values of serum cTnI, NT-proBNP, and free light chains difference were 0.25 μg/L, 11 733 ng/L, and 403 mg/L, respectively. Eight (24.2%) had more than 10% plasma cell on the bone marrow aspirate. Sixteen (47.1%) patients received bortezomib based chemotherapy and overall hematologic response rate was 58.3%. Median overall survival (OS) was 4 months. The estimated OS at 3, 6, 12, and 24 months was 51.3%, 44.0%, 35.2%, and 29.6%, respectively. Fourteen (41.2%) patients died within 3 months after the diagnosis. The estimated 1-year survival rate for the patients who got hematologic response, without hematologic response, and palliative treatment was 90.9%, 11.1%, and 0, respectively (P<0.001) .@*Conclusion@#Patients with very high risk pAL had very poor prognosis and the early death rate remained high. Those patients who obtained hematologic remission would have significantly better outcomes.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the usage of Mayo staging system in Chinese patients with primary light chain (LC) amyloidosis.</p><p><b>METHOD</b>Clinical data, treatment and outcome of 162 primary LC amyloidosis patients with Mayo Clinic staging in Peking Union Medical College Hospital from January 2009 to June 2015 were retrospectively analyzed.</p><p><b>RESULTS</b>The median age of 162 patients with Mayo Clinic 2004 stage was 57 (20-81) y, of them 62.3% were male. The number of patients with stage I to III were 44 (27.2%), 69 (42.6%), and 49 (30.2%), respectively. The median overall survival was not reached, 23 months and 12 months in patients with Mayo Clinic 2004 stage I, II, and III, respectively (P<0.001). Among 128 patients with Mayo Clinic 2012 stage, 48 patients (37.5%), 32 patients (25.0%), 32 patients (25.0%) and 16 patients (12.5%) were staged as Mayo Clinic 2012 stage 1 to 4, and the median OS was not reached, not reached, 13 months and 3 months, respectively (P<0.001).</p><p><b>CONCLUSION</b>Mayo Clinic staging systems had important prognostic value in patients with primary LC amyloidosis.</p>
