Summary
Brief summary
This tissue collection substudy aims to store primary tissue samples at the Breast Cancer Trials (BCT) Tissue Bank in Newcastle, NSW, for use in future research projects to investigate various aspects of cancer.

Who Is It For?
Patients who are randomized to the ANZ 1501 POSNOC study in Australia and New Zealand.

Trial Details:
If you decide to take part in the main POSNOC study, you will be asked to sign and date a consent form. As part of the study, researchers will take samples of your tumour from your breast cancer surgery for use in future research. You will not need to have any additional tissue biopsies taken as a result of giving your permission to use your tissue for this purpose.

All primary tumour tissue samples will be stored at the BCT Tissue Bank for use in future research projects to investigate various aspects of cancer. All future research on stored tissue will have ethics approval and will be conducted under the supervision of the BCT Scientific Advisory Committee. Research conducted on the tissue samples will not be used for commercial gain.

Tissue banking is a way of securely storing samples for use in future research when new tests may become available, so we expect to keep your samples for a long time. The use of banked tissue in future research may help researchers learn more about different types of cancers and how to treat them.


The diversity within cancer tissue means that the most reliable information about breast cancer is obtained from clinical trials, as these often look at very specific types of breast cancers. Therefore, they can aim to tailor treatments to the individual patient to find the best outcome for that patient. Translational research (looking at what happens in tissue/tumour cells and then translating the findings to find the most effective way to treat a patient) is best conducted when linked to the information gained from a clinical trial.

Patients will not be identified by name. The only identification of tissue will be by a patient study number, hospital or clinic number, patient initials and date of birth. All testing performed on tumour tissue will be performed anonymously. Tumour tissue will be stored indefinitely.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
This project is for tumour tissue collection only.

The tumour samples are to be used by researchers in the future to better understand the nature of breast cancer and how patients respond to treatment in this study. The precise projects for which this tissue will be used cannot be determined until the outcomes of the study are known.

Tissue collected for this project will not be released until after planned protocol analyses are completed. The tissue specimens are intended for use in projects that are likely to translate into improved outcomes for patients with breast cancer, either directly, or via future projects.

Patients will not be identified by name. The only identification of tissue will be by a patient study number, hospital or clinic number, patient initials and date of birth. All testing performed on tumour tissue will be performed anonymously. Tumour tissue will be stored indefinitely.
