Overview

Multiple myeloma (MM) is still an incurable hematological tumor, and renal involvement is the main factor of poor prognosis. The recovery of renal function can partially reverse its poor outcome. Although the 5-year survival rate of MM patients has significantly improved after entering the era of new drugs, patients with severe renal insufficiency still have a high early mortality.The purpose of this study is to investigate whether early intensive chemotherapy can reverse the proportion of renal insufficiency, is to investigate the treatment effect of RIMM patients with different renal pathological types, and is also to investigate whether autoHSCT can further partially save renal function in RIMM patients.
