The Pathology Core Facility (PCF) of Robert H. Lurie Comprehensive Cancer Center (RHLCCC) at Northwestern University is established in 1997. PCF is functionally divided into three divisions/units, including core lab, biorepository and clinical trials unit. Core lab includes all related tasks of routine histology, immunohistochemistry, molecular work, and digital pathology (all aspects of a research-based anatomic pathology laboratory including formalin fixation and paraffin embedding, automated and manual immunohistochemistry, tissue microarray design and construction, and automated whole slide scanning for digital pathology applications, including advanced image analysis capabilities). Biorepository division includes tissue and biospecimen procurement (a workflow that complements clinical patient care, the consent procedures which include statement of basic, translational and clinical research and PDX studies for potential therapies), detailed sample annotation (pre-analytic variables such as cold post-surgery time, frozen section evaluation, specimen tracking, and a quality management program); and well-controlled biospecimens and procedures (ensuring that clinically meaningful and reproducible data emerge from investigation). The clinical trials unit (CTU) provides service of institution, regional and national network and prepares trial cases of fast turnaround time and high quality trial materials and patients’ satisfaction. In conjunction with the Cancer Center’s Clinical Trials Office, the clinical trials unit participates in both industry based clinical trials and investigator initiated clinical trials.
