Neuroendocrine tumors (NETs) arise in most organs of the body and share many common pathologic features. However, a variety of different organ-specific systems have been developed for nomenclature, grading, and staging of NETs, causing much confusion. This review examines issues in the pathologic assessment of NETs that are common among primaries of different sites. The various systems of nomenclature are compared along with new proposal for grading and staging NETs. Although differences… 
Pathology reporting of neuroendocrine tumors: essential elements for accurate diagnosis, classification, and staging.
TLDR
This review will present the most widely used systems for classifying, grading, and staging NETs and will summarize the recommendations for the data to be included in standard pathology reports of these uncommon tumors.
PROGNOSTIC ROLE OF KI-67 INDEX AND MITOTIC INDEX IN NEUROENDOCRINE TUMORS OF HETEROGENOUS ORIGIN
TLDR
There was a significant association between tumor grading and metastasis where tumor grading served the most important predictor of outcome.
Classification of Neuroendocrine Tumors: Consensus Guidelines for the Management and Treatment
TLDR
This review examines issues in the pathologic assessment of NETs that are common among primaries of different sites and compares various systems of nomenclature, such as the distinction of well-differentiated from poorly differentiated, and the significance of proliferative rate in prognostic assessment.
The pathological diagnosis of neuroendocrine tumors: common questions and tentative answers
TLDR
An overview of the most frequently asked questions and an attempt to provide practical answers related to NEN diagnosis in the daily pathology work are provided.
Emerging Therapeutic Concepts and Latest Diagnostic Advancements Regarding Neuroendocrine Tumors of the Gynecologic Tract
TLDR
The main concept of this novel classification framework is to align it to all other body sites and make a clear distinction between well-differentiated neuro endocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs).

The ENETS/WHO grading system for neuroendocrine neoplasms of the gastroenteropancreatic system: a review of the current state, limitations and proposals for modifications.
TLDR
The genesis of the currently used ENETS/WHO classification system is reviewed, including some of the most recent proposals that suggest modifications to the current system.
Diagnostic Approach to Neuroendocrine Neoplasms of the Gastrointestinal Tract and Pancreas.
TLDR
Current approaches to the diagnosis and prognostic classification of GEP-NENs are examined, focusing on the critical use of morphological parameters and immunohistochemical stainings, including diagnostic, site-specific and progostic markers.

TLDR
Although there remains disagreement among experts about the specific classification system thatshould be used, there is agreement about the fundamental pathology data that should be reported.
Neuroendocrine carcinomas of the lung: a critical analysis.
TLDR
Current concepts regarding the classification of these neoplasms and the role of this classification in the authors' daily practice are reviewed and how it may impact treatment is discussed.
Predicting Prognosis in Gastroentero-Pancreatic Neuroendocrine Tumors: An Overview and the Value of Ki-67 Immunostaining
TLDR
This review seeks to better establish what the consensus is on the role of the Ki-67 proliferation index as a prognostic indicator of long-term outcome in pancreatic neuroendocrine tumors and concludes that most studies favor the utility of the ki- 67 proliferation index despite different critical percentages and in concert with other pathological parameters in the routine work-up of PETs.
TNM staging of midgut and hindgut (neuro) endocrine tumors: a consensus proposal including a grading system
TLDR
The proposed tumor–node–metastasis (TNM) classifications are based on the recently published ENETS Guidelines for the Diagnosis and Treatment of gastroenteropancreatic NETs and follow the previous proposal for foregut tumors.

TLDR
Pancreatic endocrine neoplasms exhibit a spectrum of biologic behavior, and the proposed benign (macroadenoma) and borderline groups contain potentially aggressive tumors.
TNM staging of foregut (neuro)endocrine tumors: a consensus proposal including a grading system
TLDR
The tumor–node–metastasis proposal for foregut NETs of the stomach, duodenum, and pancreas that was designed, discussed, and consensually approved at this conference is reported.
Determining prognosis in patients with pancreatic endocrine neoplasms: can the WHO classification system be simplified?
TLDR
Accurate prognostic information can be obtained by combining tumor size and metastases with simple grading information based on necrosis and mitotic rate.
Immunohistochemical staining of cytologic smears with MIB-1 helps distinguish low-grade from high-grade neuroendocrine neoplasms.
TLDR
It is demonstrated that MIB-1 dramatically stratifies NENs as low-grade or high-grade, and the proliferation index also correlates with grade of NEN in cytology specimens.
Pulmonary atypical carcinoid: predictors of survival in 106 cases.
TLDR
AC is an aggressive neuroendocrine neoplasm with survival intermediate between TC and LCNEC and SCLC, and the role of chemotherapy and radiation therapy remains to be proven.
Prognostic criteria in nonfunctioning pancreatic endocrine tumours
TLDR
Four prognostic groups of nonfunctioning pancreatic endocrine tumours showed distinct survival curves, which were significantly affected by vascular microinvasion, Ki67 proliferative index and metastases.
