ectopic endocrine syndrome

Paraneoplastic endocrine syndrome refers to endocrine dysfunction caused by tumors producing hormones or hormone-like peptides. Its mechanism involves cross-immune reactions, selective expression of oncogenes, etc. Some active substances secreted by certain tumors that cause endocrine symptoms do have hormone-like effects but have no corresponding natural hormones (such as NSILA). Therefore, this type of syndrome can be broadly referred to as "ectopic endocrine syndrome," which is more practical.
