You will be presented pre-selected fields of view (FOV) digitally or on a microscope (Figure below, left). For each FOV, you will be prompted for the tumor-associated stromal TIL density, which is a number from 0-100. Once you have determined stromal TIL density for each FOV, you will type or click the value using the software’s guided user interface (Figure below, right). Study training materials on TIL density evaluations can be found in the following section and may be completed ahead of time.
