Obesity and myeloma: Clinical and mechanistic contributions to disease progression

Area of Science:

• Hematology
• Oncology
• Epidemiology

Background:

• Obesity and obesogenic behaviors correlate positively with monoclonal gammopathy of unknown significance (MGUS) and multiple myeloma (MM).
• Body weight is the only known modifiable risk factor associated with MM, presenting a potential target for disease prevention.
• Mechanistic links between body weight and MM progression remain largely unexplored.

Purpose of the Study:

• To review epidemiological data on weight, body composition, and MM progression.
• To summarize the molecular mechanisms by which obesity influences myeloma cell phenotype and signaling.
• To propose future research directions for understanding body weight's role in MM pathogenesis.

Main Methods:

• Literature review of epidemiological studies correlating body weight and MM.
• Analysis of molecular mechanisms linking obesity to myeloma cell signaling.
• Outline of future preclinical research using animal models.

Main Results:

• Epidemiological data show a positive association between obesity and MGUS/MM.
• Obesity influences myeloma cell phenotype and signaling pathways.
• Future research is needed to elucidate the role of body weight in the bone marrow microenvironment and MM pathogenesis.

Conclusions:

• The association between obesity and MM highlights body weight as a modifiable risk factor for MM prevention.
• Further research into the molecular mechanisms and the bone marrow microenvironment is crucial.
• Findings may inform public health messages for MM prevention.
