Analysis of the epidemiological characteristics of multiple myeloma and clinical factors affecting the course of the disease

Abstract

Multiple myeloma (MM) is the second most common malignant neoplasm of the hematopoietic system. Survival rate has improved significantly in patients over the past decade with the use of new therapeutic strategies. The absence of adverse factors at the time of diagnosis does not always determine a positive course of the disease. Therefore, the search for prognostic factors is relevant. The article presents data based on the epidemiological characteristics and clinical factors of MM that affected the progression-free survival. We have shown that a significant excess of the levels of IL2, IL6, TNF, the level of clonal CD138+ >20% at the time of diagnosis is associated with an increase in the frequency of disease progression.A decrease in progression-free survival was detected at kidney damage, anemic syndrome, infectious complications, multiple skeletal bone lesions, genetic changes at the time of diagnosis and did not depend on the type of immunoglobulin secretion.
