The most common paraneoplastic syndrome associated with small cell lung cancer is the secretion of antidiuretic hormone (ADH), which leads to the development of syndrome of inappropriate antidiuretic hormone secretion (SIADH). This results in low sodium levels, hyponatremia, and can cause symptoms such as confusion, seizure, and coma. Secretion of adrenocorticotropin hormone (ACTH) can also occur but is less common than SIADH. Secretion of thyroid stimulating hormone (TSH) and luteinizing hormone (LH) are even less frequent.
