Longitudinal Data Registry of Plasma Cell Dyscrasia

July 30, 2026 updated by: Peng Liu, Shanghai Zhongshan Hospital

Longitudinal Data Registry of A Spectrum of Plasma Cell Dyscrasia With Long-term Follow-up

The goal of this multicenter observational study is to better understand the clinical and molecular characteristics, disease progression, treatment response, and clinical outcomes of patients with plasma cell dyscrasias, including monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma, and light-chain amyloidosis. The study is led by Zhongshan Hospital, Fudan University, in collaboration with 18 other research centers in China. The main questions it aims to answer are:

Which clinical, laboratory, pathological, immunologic, cytogenetic, and genomic characteristics are associated with disease progression, treatment response, and patient outcomes? How do plasma cell dyscrasias and their underlying clones evolve over time? Can clinical and molecular information be used to develop models that predict disease progression and patient outcomes?

Researchers will collect and analyze historical and prospective clinical data from participating centers and follow patients over time. Participants' clinical course, laboratory and other test results, treatments, disease progression, and outcomes will be recorded and analyzed. This is an observational study and does not assign participants to any specific treatment.

Conditions

Detailed Description

PCD is a spectrum of diseases that is being gradually understood in Asia. This study aims to observe and describe the clinical and genetic characteristics of Chinese PCD patients, and to explore the relationship between the characteristics and pathogenesis. It also aims to discover the potential distinct clonal evolution patterns among different subtypes of this disease spectrum. This study is a non-interventional, real-world, multicenter study. All registered data are collected from real-world clinical practice. The medical data include patient demographics, tumor characteristics, laboratory examinations, treatment history, adverse reactions, efficacy results, and potential prognostic factors.

Design Details

Cohorts and Interventions

Group / Cohort
Enrolled patients
The final personalized management strategy is determined based on both current conventional treatment options and physicians' and patients' preferences. The following agents might be applied: proteasome inhibitors (PIs), immunomodulatory drugs (IMiDs), alkylating agents, anti-CD38 monoclonal antibodies, bispecific antibodies, and cell therapy, with or without steroids.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
