Ki-67 assessment of pancreatic neuroendocrine neoplasms: Systematic review and meta-analysis of manual vs. digital pathology scoring
2022
Ki-67 assessment is a key step in the diagnosis of neuroendocrine neoplasms (NENs) from all anatomic locations. Several challenges exist related to quantifying the Ki-67 proliferation index due to lack of method standardization and inter-reader variability. The application of digital pathology coupled with machine learning has been shown to be highly accurate and reproducible for the evaluation of Ki-67 in NENs. We systematically reviewed all published studies on the subject of Ki-67 assessment in pancreatic NENs (PanNENs) employing digital image analysis (DIA). The most common advantages of DIA were improvement in the standardization and reliability of Ki-67 evaluation, as well as its spee…
Medikamentöse Therapie bei Karzinoiden des Gastrointestinaltraktes
2001
Carcinoid tumors are rare and slowly growing neuroendocrine tumors of the foregut, midgut and hindgut. Drug therapy is of special importance in patients with inoperable metastasising disease. This palliative therapy is aimed at reduction of the hormone-dependent symptoms and inhibition of tumor growth. Somatostatin analogues, alpha-interferon and various chemotherapeutic agents are used for this purpose. Drug therapy can be supplemented by surgical and radiological intervention through interdisciplinary cooperation of the surgeon, radiologist, endocrinologist and gastroenterologist.
