What is a Cancer Biobank?

Cancer biobanks are helping to transform the future of cancer care. Providing researchers with access to vital biological samples and clinical information, they are helping to accelerate the development of new treatments, improve our understanding of cancer and advance approaches like precision medicine.

Many medical breakthroughs rely on access to high-quality biospecimens and clinical data, making cancer biobanks an important resource in the fight against the disease. But what exactly is a cancer biobank, and what does it mean for the future of cancer care in the region?

What is a cancer biobank?

A cancer biobank is a specialized, secure facility that collects, stores, manages and processes biological samples along with associated health data. Samples are donated by patients for research purposes and may include:

• Blood
• Tumor tissue
• Healthy tissue
• Saliva
• Bone marrow
• DNA, RNA, and other molecular material derived from donated samples

The samples are stored under strictly controlled conditions to preserve them for future research. Each sample is linked to relevant clinical and health information of the patient who donated it, which includes information such as their diagnosis, treatment history and outcomes.

Researchers then study the samples to gain a better understanding of the biology of cancer, aiming to identify new ways to prevent, diagnose, and treat different types of cancer.

The donor’s privacy is protected at all times through rigorous security and confidentiality measures.

Why are cancer biobanks so important?

Every person’s cancer is different. The same type of cancer can affect different people in different ways and respond very differently to the same treatment.

This is because every tumor has unique characteristics, which influence how it grows, spreads and responds to treatment.

With access to a large pool of samples, from a diverse range of patients, researchers can better understand these differences, helping them to develop personalized therapies and to understand which treatments are likely to be most effective for each patient.

Cancer biobanks may help advance research in:

• Early cancer detection
• More accurate diagnosis
• Cancer prevention
• Development of targeted cancer therapies
• Identification of genetic mutations that affect the way cancer behaves
• Predicting how a patient may respond to treatments
• Understanding why some cancers don’t respond to certain treatments
• Advancing immunotherapy research.

Many advances in cancer diagnosis and treatment have been made possible, in part, through access to biospecimens collected and stored in cancer biobanks.

What is precision medicine in cancer?

One of the most promising areas of cancer research is precision medicine. Precision medicine, or personalized medicine, is an approach that tailors the diagnosis, treatment and management of cancer to each patient’s tumor.

Rather than adopting a one-size-fits-all approach, precision medicine uses information about the patient’s genes, their overall health, and the tumor’s unique characteristics to develop more personalized treatment plans.

With access to stored tumor samples and associated clinical outcome data, researchers can identify patterns that help predict how different tumors may respond to various therapies, supporting the development of personalized treatment approaches.

What does donating to a cancer biobank mean for patients?

Donating to a biobank is a simple process. Samples are usually taken during procedures that are part of a patient’s care, such as during blood tests, biopsies or surgery. Tumor tissue is tissue that is removed as part of cancer diagnosis or treatment and it is not required for diagnostic purposes.

Participation is entirely voluntary and samples will never be collected without the patient’s consent.

While donating to a cancer biobank does not directly affect a patient’s immediate care, they are contributing to future medical discoveries and helping researchers to shape the way cancer is diagnosed, treated and prevented for generations to come.

Are samples secure and protected?

Patient privacy is paramount at biobanks. There are stringent security and legal standards in place to govern the way samples and clinical data are accessed, stored and shared.

Any personal information is removed from samples and replaced with coded information. Only approved researchers have access to samples, and any work conducted on the samples is performed under regulated protocols.

Driving cancer research

Cancer research is advancing at an unprecedented rate. Technologies such as AI, genomic sequencing and precision medicine mean we understand more about cancer than ever before.

Access to biological samples is essential to much of this progress. Researchers are able to develop innovative therapies, explore new research avenues and validate their discoveries.

As more and more patients choose to donate, and the pool of samples grows, these contributions have the power to shape the future of cancer care.
