Neuroblastoma (occurs in 2-3% of peds cases), breast, ovarian, small-cell carcinoma. A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of a tumor in the body (usually a cancerous one), specifically due to the production of chemical signaling molecules (such as hormones or cytokines) by tumor cells or by an immune response against the tumor. SIADH and EAS are the most common paraneoplastic endocrinopathies associated with SCLC. Small cell lung cancer commonly leads to paraneoplastic syndromes that affect the endocrine and neurological functions. Paraneoplastic syndromes may develop before the diagnosis of carcinoma is made.

In a long-term study of quality of life and survival in patients with LambertEaton myasthenic syndrome (LEMS), Lipka and colleagues reported that survival was significantly longer in patients with small cell lung cancer (SCLC) and LEMS than in those with SCLC alone (overall median survival 17 vs 7.0 months, P< 0.0001).
