The Ki-67 index is an established prognostic factor in gastrointestinal neuroendocrine tumors (GI-NETs) and defines tumor grade. It is currently estimated by microscopically examining tumor tissue single-immunostained (SS) for Ki-67 and counting the number of Ki-67-positive and Ki-67-negative tum...
vessel tumor emboli in biopsy specimens obtained before neoadjuvant therapy and in the surgical specimens obtained after neoadjuvant therapy according to the grading system we devised are significant histological outcome predictor for invasive ductal carcinoma (IDC) patients who received neoadjuvant therapy. ...
In addition, tumors were classified according to the architectural grading system based on histologic subtype.4,12 as (1) low grade—adenocarcinoma in situ, minimally invasive adenocarcinoma or lepidic predominant; (2) intermediate grade—papillary or acinar; (3) high grade—micropapillary or solid....
(6) reporting rules for Gleason grading reporting secondary patterns of higher grade when present to a limited extent; (7) reporting secondary patterns of lower grade when present to a limited extent; (8) reporting percentage pattern 4; (9) general applications of the Gleason grading system; (...
The Gleason grading system is widely used for prostate grading [3], which classifies the prostate cancer as Grades 1–5, as shown in Figure 1. Higher Gleason grades indicate a higher malignancy level. The Gleason score is calculated using the sum of the two most dominant Gleason grades ...
Figure 4 illustrates the distribution of instances across the KL grading system for assessing knee OA severity. In addition, this study uses X-rays of the knee in order to perceive KL grades from one X-ray image of both knee joints, we keep only those X-ray images with KL grades ...
