Overview
The overall objective of the Tissue Procurement Facility (TPF) is to collect and provide needed tissue specimens to Stanford Cancer Center investigators to support their cancer-related research. TPF activities and services include collecting and banking freshly frozen tumor and normal tissues from excess surgical material and from autopsy, providing fresh tumor tissue for viable cell studies, processing and banking serum specimens from cancer patients, maintaining a tissue database with links to clinicopathological data, providing histological staining and pathological review, coordinating patient consent and ensuring regulatory compliance.
Services
Procurement and Analysis Services
- Tissue Procurement
The TPF procures tumor and normal tissues from excess surgical materials and from autopsy. Targeted collections are carried out to meet specific investigator needs. In addition, a broad spectrum of tumor types is banked to meet anticipated future needs of investigators.
- Serum Procurement
The TPF collects, processes and banks freshly frozen serum (or plasma) from cancer patients. Blood is typically drawn pre-operatively, and banked serum is provided to investigators for biomarkers studies and related research.
- Histological Analysis
The TPF provides pathological expertise and services, including the preparation of stained and unstained tissue sections, and the expert review of specimens, stained slides and pathological diagnoses.
Support Services
- Coordinating Patient Consent
The TPF has recently implemented a Health Insurance Portability and Accountability Act (HIPAA)-compliant "universal" (also known as "blanket") patient consent protocol for tissue procurement. Consent is typically obtained preoperatively, at or near the time of surgical consent.
- Database Management
The TPF manages a database to track tissue specimens and associated clinicopathological information. This custom database, the STRIDE (Stanford Translational Research Integrated Database Environment) tissue banking application, was developed and is maintained by the developing shared resource, Cancer Informatics.
- Quality Assurance
Quality is ensured at multiple levels. Prior to distribution of tissues, a pathologist evaluates an H&E-stained frozen section of each specimen to confirm the histological diagnosis, to estimate the percent tumor and to document the presence of normal epithelium, necrosis, fibrosis, etc. To evaluate tissue quality, the TPF periodically surveys investigators regarding the intactness of extracted molecular components (e.g., rRNA).
Operation
The TPF is located in the Lorry Lokey Stem Cell Research Building, Suite G0815. Distribution of tissues to investigators and use of TPF equipment occurs at the facility. The facility hours are from 8:00 am to 6:00 pm, Monday through Friday. The working hours of the two tissue technicians are staggered to accommodate tissue procurements any time between 8:00 am and 6 pm on weekdays, ensuring capture of late-afternoon surgeries. The on-call surgical pathology resident also is available (for a fee) to accommodate infrequent “after-hours” tissue procurements.
Contact
To access tissues or other services, the investigator is encouraged to first contact the director (Dr. Longacre) to discuss and assess the general feasibility of the service request. The investigator then submits to the facility a completed Service Request Form (http://tissuebank.stanford.edu), which is reviewed by two committee members of the TPF advisory board. If additional expertise is required, the director may enlist a third ad hoc faculty member who is not on the committee. At the next committee meeting (currently held monthly), the service request is discussed, and the recommendation voted on by the committee. The investigator may appeal the advisory board’s decision in writing to the TPF director, and if the decision regarding the appeal is unsatisfactory to the investigator, a second appeal may be made to the Cancer Center associate director of shared resources. For approved requests, specimens are distributed only after receiving a copy of the investigator’s IRB/PRMS approval letters and a signed Letter of Research Agreement.
