Monoclonal gammopathies (MG) are classically associated with lytic bone lesions,
hypercalcemia, anemia, and renal insufficiency. However, in some cases, symptoms
of endocrine dysfunction are more prominent than these classical signs and
misdiagnosis can thus be possible. This concerns especially the situation where
the presence of M-protein is limited and the serum protein electrophoresis (sPEP)
appears normal. To understand the origin of the endocrine symptoms associated
with MG, we overview here the current knowledge on the complexity of interactions
between cytokines and the endocrine system in MG and discuss the perspectives for
both the diagnosis and treatments for this class of diseases. We also illustrate
the role of major cytokines and growth factors such as IL-6, IL-1?, TNF-?, and
VEGF in the endocrine system, as these tumor-relevant signaling molecules not
only help the clonal expansion and invasion of the tumor cells but also influence
cellular metabolism through autocrine, paracrine, and endocrine mechanisms. We
further discuss the broader impact of these tumor environment-derived molecules
and proinflammatory state on systemic hormone signaling. The diagnostic
challenges and clinical work-up are illustrated from the point of view of an
endocrinologist.
