[note 1] Gleason scores are commonly grouped into "Gleason grade groups", which predict disease prognosis: a Gleason score of 6 is Gleason grade group 1 (best prognosis). A score of 7 (with Gleason scores 4 + 3, or Gleason scores 3 + 4, with the most prominent listed first) can be grade group 2 or 3; it is grade group 2 if the less severe ...
For example, if the most prevalent pattern/grade is 2, and the second most prevalent grade is 1, then the Gleason score is 2+1=3. If the neoplasm has only one pattern, the grade of that pattern is doubled to obtain the score. For example, if a tumor is entirely grade 1, the Gleason score would be 1+1=2.

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 ...
As if cold and flu season weren't bad enough, this winter is turning out to be a particularly bad one for stomach bugs. By December 11, 495 outbreaks of norovirus had been reported nationwide ...
The WHO grade has four categories of tumors: Grade 1 tumors are slow-growing, nonmalignant, and associated with long-term survival. Grade 2 tumors are relatively slow-growing but sometimes recur as higher grade tumors. They can be nonmalignant or malignant. Grade 3 tumors are malignant and often recur as higher grade tumors.
The prognosis for a subependymoma is better than for most ependymal tumors, [3] and it is considered a grade I tumor in the World Health Organization (WHO) classification. They are classically found within the fourth ventricle , typically have a well demarcated interface to normal tissue and do not usually extend into the brain parenchyma ...
