Malignancy in neuromuscular patients on chronic IVIG

Chronic IVIG therapy may be associated with a reduced incidence of cancer, particularly among patients with CIDP. Additionally, we found a negative correlation between duration of IVIG treatment and cancer incidence, suggesting a potential protective effect of long-term IVIG exposure. To our knowledge, this is the first study to explore the relationship between sustained IVIG therapy and long-term cancer risk in neuromuscular autoimmune diseases.
