Lack of high quality breast cancer tissue and attendant clinical information has been a major impediment for those working in the field of breast cancer research. In response to these needs the Australian Breast Cancer Tissue Bank was established with the support of major Australian funding bodies.
The aims of the resource were to establish a standardised framework for the ethical and appropriate recruitment of breast cancer tissue donors; to collect and store cancer and matched normal tissue, blood and associated standardised clinical, longitudinal and outcome data from breast cancer patients; and to make material available for basic and translational research . Operating principles are based on best practice guidelines , and encompass two significant strategic features: Integration of tissue banking into clinical practice; and the development and adoption of web-based data management solutions .
Both tissue and blood samples are collected and stored and a central processing laboratory is able to perform DNA and RNA extractions, sectioning of tissue, creation of Tissue Micro Arrays (TMAs) and digital imaging of stained sections of tumour. The latter are made available for viewing on the ABCTB website  so that researchers can review and select individual cases. Data is collected via both electronic and manual methods. The ABCTB developed an auditing tool within its database to ensure accuracy of key data fields and maintain data integrity . The ABCTB participates in consortia studies such as the Breast Cancer Association Consortium (BCAC) and the Triple Negative Breast Cancer Consortia (TNBC). This allows ABCTB samples to be pooled in very large cohort studies [6,7]
Biological samples and associated data.
ABCTB consists of a central management hub located at the Westmead Millennium Institute in New South Wales, Australia, with collection centres and affiliate sites distributed across Australia .

Temporal coverage for accessibility
- Donors are recruited and consented in breast cancer clinics at the time of diagnosis of breast cancer. [SOPs are in place for obtaining informed consent; for consent form management; for withdrawal of consent; for confidentiality agreements by staff].
- The ABCTB collects blood, tissue and clinical data from consenting patients.
- Bloods are collected from donors by clinical staff and tissue is collected from surgery via diagnostic anatomical pathology laboratories and only if there is excess tissue that is not required for diagnostic purposes as assessed by a pathologist. [SOPs for blood processing and storage; tissue processing and storage; data entry].
- Clinical data is collected from medical records, pathology reports, cancer registries and clinical databases. [SOPs for data collection and entry: pathology data; surgical details; demographics; clinical history].
- Tissue sections from FFPE blocks are reviewed for tumour content by a qualified pathologist [SOP for pathology review].
- Donor information, specimen details and clinical data is stored in a secure customised SQL (Caisis) database. [SOPs for data management; database operation; data storage and security; and data auditing].
- Longitudinal data is collected on the donors and their clinical outcomes will be followed for ten years.
- A website provides information for researchers and donors.
- EDTA (blood)
- Snap freeze tissue in liquid nitrogen
Type of long-term preservation
- Formalin Fixed Paraffin Embedded (FFPE)
- Fresh into media (for specific project requests only)
- Dried blood spot cards
All samples are labelled with a unique code and contain no patient identifiable information. Samples are stored in temperature monitored freezers and tanks that are locked and accessible only by ABCTB employees.
- -80°C (Serum; plasma; whole blood; DNA)
- -196°C (Tissue; white cell buffy coat)
- Room temperature (Blood spot cards; FFPE blocks; TMAs)
- Storage duration: 7 years plus
Shipping temperature from patient/source to preservation or research use
Various from: -190°C (liquid nitrogen), -56°C (on dry ice); 0-4°C (on ice); room temperature (18-25°C).
Shipping temperature from storage to research use
- -80°C to -196°C (Tissue)
- -56°C (DNA, blood products)
- Room temperature (FFPE sections)
Quality assurance measures
- % tumour content reviewed by pathologists
- RIN for RNA samples
- Control sample on every DNA extraction run
- Participate in external QAP scheme for RNA, DNA and tissue histology
- BRISQ report provided
- Auditing of essential data fields 
- Samples collected across all collection nodes follow common SOPs
Source of associated data
- Hospital health records both paper and electronic
- Health records from individual specialist’s rooms/clinics
- NSW Cancer registry – via hospital data feeds
- G.P. Surgeries
- Family history via questionnaires
- Death registry
The main ethical multi-site approval for the ABCTB is provided by the Royal Prince Alfred Hospital Zone Ethics Committee in New South Wales, Australia.
Protocol No X12-0279 (prev X08-0124) & HERC/08/RPAH/215 – “Australian Breast Cancer Tissue Bank”. Multi-site approval was initiated on 6/08/2008. Prior to this date, collection sites had individual approvals in place.All collection/affiliate sites also have site specific ethical approvals. Samples are intended to be stored indefinitely.
Funds supporting the resource are mostly via competitive research grants and of short term duration. Planning for long term operational activities is difficult with lack of financial security.

Has been open for applications since 2008.
Applications to the resource are initiated by the researcher by submission of an on line Expression of Interest. This is reviewed by the ABCTB and if the material and/or data are available and the project meets ABCTB criteria a full application is invited. The researcher is provided with a log in to complete the application on line, which also allows upload of required documents such as evidence of funding and ethical approvals. Following receipt of a full application, all applications for material and data must be assessed and approved by the ABCTB Access Committee to comply with scientific standards. Independent scientific review is sought for project evaluation.
All applications must have ethical approval for the proposed research and must enter into an MTA with the ABCTB before the material is released . A partial cost recovery mechanism is in place (http://www.abctb.org.au/abctbNew2/Cost_recovery_Schedule_Dec_2010.pdf). At the conclusion of the project, any data generated must be returned to the ABCTB and this is made available for other users.
(4) Reuse potential
Specimens are provided to projects on a non-exclusive basis therefore samples from the same donor may be used in several different projects. If the researcher requires DNA and/or RNA this is extracted by the ABCTB preserving the bulk of the specimen to be available for other research projects.
As a condition of supply of material, the recipient of samples and/or data must agree to return findings to the ABCTB on conclusion of the research purpose. Such data is then available for the use of others.
