Tissue collection

After removal of the tumour sample a stopwatch is started and the pathologist is informed about the arrival of a tissue for the biobank. The surgical specimen is immediately transported to the lab whereas the pathologist first collects sections for routine histopathological and cytopathological routine analyses. From the remaining tumour specimen, small sections are collected for research purposes and immediately frozen in liquid nitrogen.

As soon as the samples are placed into liquid nitrogen, the stopwatch is stopped and the time is registered on the study application form. Other useful information like date, name surgical, name pathologist, and others are also registered on the application form.

If possible, sections of the surrounding normal tissue are also collected in the same way. Samples placed in liquid nitrogen are transported to the research lab and retained in a cryovial. These samples are stored in the gas phase of liquid nitrogen.
