Autoimmunity associated with tumor cell development seems an important mechanism by which to prevent progression to clinical cancer. In this brief review, tumor autoantigens associated with paraneoplastic syndrome, non-HLA-associated organ-specific autoimmune diseases, and the highly cell-specific autoimmune eradication of the islet beta cells in type 1 diabetes are compared and discussed. It is suggested that autoreactivity is important in preventing tumor formation; however, it may be at the expense of the development of autoimmune disease. Although the cytotoxic T lymphocytes (CTL) induction by HLA class I has been studied and used in clinical trials, little is understood about the initiation and HLA class II mediated induction of an immune response to neoplastic cells. This induction apparently takes place because paraneoplastic disorders are often due to an immune response to the tumor cell resulting in a cross-reactivity with a normally expressed autoantigen on a remote nontumor-associated target cell. The problem of immune surveillance to eradicate neoplasm or downregulate pathological autoimmunity are therefore closely related phenomena. An improved understanding of immune mediated tumor suppression should therefore greatly benefit immunotherapy of type 1 diabetes, and the two areas of research would benefit from an interdisciplinary endeavor.

Glucagonoma is a hormonally active rare pancreatic neuroendocrine tumour causing an excess of glucagon. This is a narrative review based on a multidisciplinary approach of the tumour. Typically associated dermatosis is necrolytic migratory erythema (NME) which is most frequently seen at disease onset. Insulin-dependent diabetes mellitus, depression, diarrhoea, deep vein thrombosis are also identified, as parts of so-called 'D' syndrome. Early diagnosis is life saving due to potential aggressive profile and high risk of liver metastasis. NME as paraneoplastic syndrome may be present for months and even years until adequate recognition and therapy; it is remitted after successful pancreatic surgery. Thus the level of practitioners' awareness is essential. If surgery is not curative, debulking techniques may improve the clinical aspects and even the outcome in association with other procedures such as embolization of hepatic metastasis; ablation of radiofrequency type; medical therapy including chemotherapy, targeted therapy with mTOR inhibitors such as everolimus, PRRT (peptide receptor radiotherapy), and somatostatin analogues (including combinations of medical treatments). Increased awareness of the condition involves multidisciplinary practitioners.
