RCC is also associated with a number of paraneoplastic syndromes (PNS) which are conditions caused by either the hormones produced by the tumour or by the body's attack on the tumour and are present in about 20% of those with RCC. [1] These syndromes most commonly affect tissues which have not been invaded by the cancer. [1]
Paraneoplastic syndrome often occurs alongside associated cancers as a result of an activated immune system. In this scenario, the body may produce antibodies to fight off the tumor by directly binding and destroying the tumor cell. Paraneoplastic disorders may arise in that antibodies would cross-react with normal tissues and destroy them. [9]

Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors (formerly known as carcinoid tumors). [1] The syndrome is caused by neuroendocrine tumors most often found in the gut releasing biologically active substances into the blood causing symptoms such as flushing and diarrhea, and less frequently, heart failure, vomiting ...
The hepatic abnormalities are not due to tumor infiltration of the liver or intrinsic liver disease; they instead reflect the presence of a paraneoplastic syndrome. [1] Stauffer syndrome causes abnormal liver function tests, especially those that reflect the presence of cholestasis, i.e. abnormal bile flow. Hepatosplenomegaly may also be observed.
It predisposes individuals to renal cell cancer, an association denominated hereditary leiomyomatosis and renal cell cancer. [1] [2] It is also associated with increased risk of uterine leiomyosarcoma. [3] The syndrome is caused by a mutation in the fumarate hydratase gene, which leads to an accumulation of fumarate.
Paraneoplastic cerebellar degeneration (PCD) is a paraneoplastic syndrome associated with a broad variety of tumors including lung cancer, ovarian cancer, breast cancer, Hodgkin’s lymphoma and others. PCD is a rare condition that occurs in less than 1% of cancer patients.
Both tumour associated (paraneoplastic) and nonparaneoplastic conditions are recognized. Different antibodies are more or less selective for different parts of the brain. Antibodies target intracellular antigens in classic paraneoplastic syndromes, but synaptic proteins in nonparaneoplastic conditions.
