The therapy decision (e.g. type of surgery, radiation therapy, need for chemotherapy) for a particular patient also depends on the spread of the cancer in the body. This is why lymph nodes are resected during surgical removal of a solid tumor (e.g. breast or lung cancer), namely to prepare tissue slices and then perform microscopy to detect or exclude the spreading of tumor cells. We are working to develop innovative approaches, aiming to replace the over 100-year-old slice-based diagnostic procedure that allows tumor cells to be detected in the different section planes selected at random, with an immunocytological analysis of the whole sample. In addition to an exact quantification of tumor infestation, this will furthermore enable subsequent genetic analysis, allowing selection of the most suitable therapy for each patient in the future.
