Metastatic Prostate Cancer Project Explores a New Approach to Genomics Research

The project aims to improve understanding of prostate cancer genomics through direct-to-patient approach

The Metastatic Prostate Cancer Project is a research study being launched and funded by the Broad Institute of MIT and Harvard, a non-profit academic research institution whose mission is to accelerate the understanding and treatment of disease. The study is being conducted in collaboration with Dana-Farber Cancer Institute as well as advocacy partners. With this project led by Dr. Eliezer Van Allen, the researchers are exploring a new approach to genomics research in which they partner directly with patients with prostate cancer in order to speed important discoveries. 

Over the past decade, genomic characterisation of prostate tumours has shed enormous light on the molecular underpinnings of cancer. These discoveries have led to the development of novel therapies and preventive measures that have already revolutionised cancer care. Despite this progress, the genomics of prostate cancer remain poorly understood. 

The types of questions the project strives to answer include: 

  • What explains why some patients show extraordinary responses to a particular treatment?
  • What explains why some tumours never respond to a particular treatment?
  • What genetic changes explain why some tumours initially respond to therapy but laterrecur and metastasise?
  • How better treatments for prostate cancer can be developed? 

Despite the progress that has been made to begin to answer these questions, the prostate cancer researchers remain far from the goal. To get there, the detailed genomic characterisation of many clinically annotated cancer samples will be required. 

Because prostate cancer is often treated in the community setting, obtaining tumour samples for research is a major hurdle that needs to be overcome in order to further understanding of this disease. To address this, the researchers have launched in the US a nationwide study, The Metastatic Prostate Cancer Project, which seeks to empower patients to accelerate cancer research through sharing their samples and clinical information. The project leaders have developed an outreach programme in collaboration with a number of prostate cancer advocacy organisations to connect prostate cancer patients around the country with the genomics research performed at the Broad Institute, allowing them to participate regardless of where they live. 

Working with prostate cancer patients and advocates, the researchers designed a website with an online questionnaire that allows patients with prostate cancer to provide information about themselves and their cancer. Patients with prostate cancer are then offered an electronic consent form that explains the risks and benefits of the study and asks for permission to obtain a portion of their stored tumour tissue, a saliva sample, and copies of their medical records. 

Enrolled patients are sent a saliva kit and asked to mail back a saliva sample, which is used to extract germline DNA. The clinical research team may also contact the patient's pathology department and request a portion of the tumour to be sent to the Broad Institute for genomic analysis. The project researchers will ask pathology departments to share only a part of the tumour tissue, and not to share anything that might be needed for clinical care. Next generation sequencing (whole exome and transcriptome sequencing) is performed on tumour and germline DNA. 

The researchers are also exploring the use of blood biopsies for investigating tumour genomics through sequencing circulating tumour DNA. The patient may be asked to provide a blood sample, which will be obtained at a regularly scheduled blood draw. 

Sequencing data are linked to de-identified clinical information, and the resulting data are used to identify drivers of tumorigenesis, mechanisms of response and resistance to therapies, and diagnostic, prognostic, and therapeutic biomarkers. The database of clinically annotated genomic information will be shared with the NIH and the cancer research community. Study updates and discoveries are shared at regular intervals with all patients who complete the initial questionnaire. 

This direct-to-patient approach should be particularly enabling for patients with prostate cancer to participate directly in genomics research squarely focused on this disease. This project seeks to establish a patient-researcher partnership to accelerate genomic discoveries and improve outcomes in prostate cancer, and may ultimately serve as a means to build a new clinical and translational research model for all patients with cancer. 

The Metastatic Prostate Cancer Project is led by Dr. Eliezer Van Allen, an oncologist and prostate cancer researcher and directed by Corrie Painter, PhD, a cancer researcher, cancer patient and patient advocate. This project was designed and has been implemented collaboratively with metastatic prostate cancer patients, patient advocates, cancer researchers, physicians, and clinical specialists. The project leverages the power of the Broad Institute’s resources and the voice of the metastatic prostate cancer community in order to focus cutting edge genomic science squarely on people living with metastatic prostate cancer. The Advocacy partners are Prostate Cancer Foundation and Movember.
