First, they illustrate that rates of tumor regression and recurrence following initial regression are dependent upon the pathways activated by the initiating oncogene.
Of 23 assessable xenograft tumours produced by the AML cells, 14 regressed completely, 4 grew progressively and 5 grew progressively after initial regression.
Estimate the regression coefficients of the initial regression model by applying the proper method. .
An initial regression model used pre-test math accuracy (fixed effect) and grades (mixed effect) to predict math accuracy change (accuracy for all measures is proportion correct).
These variables were chosen because they were the best predictors of stand volume in the initial regression modelling of the data.
In the present study, undergraduate GPA (r = .39) had a medium correlation and was the only significant predictor of graduate GPA in the initial regression model among all four traditional and psychological factors.
This had little bearing on the initial regression findings.
Several vessels lack connection with the rest of the vasculature and present reduced lumen and signs of initial regression.
Initial regression analysis with all sense codons suggested that frequencies of only a subset of codons could explain most expression variation.
In this regard, it is of interest that treatment with reactivated memory T cells alone resulted in initial regression of the tumors, followed by a relapse a few days later.
The initial results that small subcutaneous tumors were completely eradicated by a single injection of VA7-EGFP were promising, but regrowth after initial regression of larger tumors was suggestive of emerging resistance, as seen in a human melanoma model [32].
