HTT Data Collection Training

Recruiting Advertisement: 20200928_HTT_recruitPathologists-v1.pdf (220 KB, uploaded by Brandon D. Gallas 1 year 2 weeks ago)

Below you will find a short overview and then study training materials on sTIL density evaluations. The training may be completed ahead of time.

Short Overview of Pathologist Task:

You will be presented pre-selected regions of interest (ROIs) digitally or on a microscope (Figure below, left). For each ROI, you will be prompted to record the percent tumor-associated stroma and the tumor-associated stromal TIL density (sTIL density). The sTIL density is a number from 0-100, and training for this evaluation is below. Once you have determined the sTIL density for each FOV, you will enter the value using the software’s guided user interface (Figure below, right).
