This is a multi-center, prospective, non-interventional study. Eligible newly diagnosed elderly multiple myeloma (MM) patients will receive comprehensive geriatric assessment (cGA) including ECOG scale, questionaires of ADL（activities of daily living), IADL(instrumental ADL),MNA-SF(mini-nutritional assessment), GDS(geriatric depression scale), MMSE(mini-mental state examination), SF-36 and CCI (charlson comorbidity index). Patients will get standard care for MM and receive the above assessments at baseline and after cycle 1, 4 and 12 for treating MM.Follow-up information and survival data of these MM patients would be collected. We would evaluate the cGA status of these newly diagnosed elderly MM patients and investigate the association of cGA parameters with patient's survival.

Baseline: ECOG, ADL, IADL, MNA-SF, GDS, MMSE, SF-36 and CCI; After cycle 1: ECOG,ADL,IADL,GDS and SF-36 After cycle 4: ECOG,ADL,IADL,GDS, MNA-SF and SF-36 After cycle 12: ECOG,ADL,IADL,GDS, MNA-SF and SF-36

Inclusion Criteria:

• age>=65 years old;
• newly diagnosed and untreated MM patients;
• able to provide informed consent

Exclusion Criteria:

• refused to participate;
• with concomitant amyloidosis;
• smoldering MM.

Newly diagnosed Multiple myeloma (MM) patients>=65 years old

There is no plan to make IPD available to other researchers.
