Therefore, Fuhrman grade might be inappropriate to assess the relationship of HDAC expression to tumour differentiation, which is the predominant basis for grading schemes of other tumour entities.
About one-third of the Karolinska students are admitted on the basis of grades without an interview.
The 62,000 students competing for the scholarships were judged on the basis of grades, leadership skills, community involvement and financial need.
The total marks (usually out of 100) form the basis of grades, with a grade value (out of 10) assigned to a range of marks.
In addition, the molecular basis of grade has also been examined with results showing a strong relationship between histological grade and tumor proliferation [ 6, 12].
Of these, 230 were diagnosed as HER2+ on the basis of grade 3+ IHC results, whilst 81 scored IHC2+ and were HER2 amplified on FISH (HER2/CEP17 ratio >2.0).
Students cannot be selected solely on academic qualifications, for instance, on the basis of Grade Point Averages (GPA) and Medical College Admissions Test (MCAT) scores.
Tissues investigated for the presence of nerves (NF200) and blood vessels (CD31) were separated on the basis of grade of degeneration and whether they were positive or negative for nerves and/or blood vessels (Table 1, Fig. 3).
Therefore, a rough estimate of the magnitude of selection bias was conducted by imputing the missing scores pertaining to findings on the basis of grades from the microscopy examination, as this was the only factor available correlating with abnormal histology test scores (neither gender nor the grade in anatomy correlated with performance on the test of microscopic pathology).
The biological potential of the tumour cells may vary with different types of tumours, and clinical decisions currently have to be made on the basis of grade, stage and margin status of the primary lesion as well as on microscopic findings in the SLN [ 135, 136].
