2. Neuroendocrine tumor - Wikipedia

   en.wikipedia.org/wiki/Neuroendocrine_tumor

   The grading system is based on proliferation assessed by mitotic rate and Ki-67 index and stratifies NETs into grade 1 (G1, low-grade), grade 2 (G2, intermediate-grade) and grade 3 (G3, high-grade). Tumor necrosis , although recognized as a factor associated with a potentially worse prognosis, is not included in the grading of NETs of the ...

   Cervical intraepithelial neoplasia. Cervical intraepithelial neoplasia ( CIN ), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [ 1] More specifically, CIN refers to the potentially precancerous transformation of cells of the cervix.

   Terminology. Invasive carcinoma NST is a type of breast cancer. It is one of the invasive breast cancers that originates from the breast ductal system, so that it is a type of ductal carcinoma. A defining feature of this ductal carcinoma is that it lacks the "specific differentiating features" of other types of ductal carcinomas.

6. Breast cancer classification - Wikipedia

   en.wikipedia.org/wiki/Breast_cancer_classification

   If cells are not well differentiated, they will appear immature, will divide more rapidly, and will tend to spread. Well differentiated is given a grade of 1, moderate is grade 2, while poor or undifferentiated is given a higher grade of 3 or 4 (depending upon the scale used). The Nottingham system [12] is recommended for breast cancer grading ...

   The new 2019 WHO classification and grading criteria for neuroendocrine tumors of the digestive system grades all the neuroendocrine tumors into three grades, based on their degree of cellular differentiation (from well-differentiated NET grade (G)1 to G3, and poorly-differentiated neuroendokrina cancer, NEC G3), morphology, mitotic rate and Ki ...

8. Grading of the tumors of the central nervous system - Wikipedia

   Macroscopic pathology of glioblastoma. The Kernohan grading system [4] [5] defines progressive malignancy of astrocytomas as follows: Grade 1 tumors are benign astrocytomas. Grade 2 tumors are low-grade astrocytomas. Grade 3 tumors are anaplastic astrocytomas. Grade 4 tumors are glioblastomas.

9. Gleason grading system - Wikipedia

   en.wikipedia.org/wiki/Gleason_grading_system

   Gleason score is calculated from grade as described in the text. The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy.
