The Angiosarcoma Project: Generating the genomic landscape of an exceedingly rare cancer through a nationwide patient-driven initiative
Abstract
Summary and Conclusions
The Patient Voice
Acknowledgements
Most tumor samples have not been readily available for study!
Only 5% of U.S. cancer patients are enrolled in
clinical trials!
Challenges of Studying Rare Patient Tumor Samples
Partnering Directly with Patients
And the Angiosarcoma Facebook group founded by Lauren Ryan, along with countless patients who have worked with us to develop
and implement this project.
ApproachOnline
ConsentMedical History
Tissue, Blood, Saliva
GenomicAnalysis
Reporting / Data Sharing
Electronic consent form asks for permission to obtain tumor tissue, blood, saliva, and medical records
Medical records are obtained by the study team and centrally reviewed and abstracted
Tumor blocks are requested from local pathology depts by the study team. Patients are sent saliva and blood kits
Patient specimens are characterized by ultra-low pass whole genome sequencing, whole exome sequencing and transcriptome sequencing
DataInterpretation
Genomic data is interpreted in the context of clinical data at the individual level and in aggregate across similar patients
De-identified genomic / clinical data shared widely with the research community. Overall findings regularly communicated directly to patients
GOAL: To empower patients and their families to accelerate research through sharing samples and clinical information
Over 300 women and men with angiosarcoma from 39 states have joined the ASCproject since our launch in March of 2017. Over 115 people have filled out information on behalf of a loved one who died from angiosarcoma
Participation in The Angiosarcoma Project to Date
We are grateful to all the patients with angiosarcoma cancer who are participating & have contributed their voices to this project.We thank the many patients, advocates, and advocacy groups who have worked with us to develop and implement this project.We thank our colleagues at the Broad Institute and Dana-Farber Cancer Institute for their contributions to designing, implementing, and running this project.

Patients have been involved from day 1 in conceiving, designing, implementing, testing, and refining this project. Patients have been partners in this project from the beginning.
98% submitted the 20-question survey
96% response rate to each question (all are optional)
294 participants have provided detailed clinical and demographic data, including information on treatments and responses
260 patients have consented to share medical records and allow next-generation sequencing on their tumor & saliva samples. 151 have returned saliva samples, 42 have returned blood biopsies
Disease Characteristics:• Dates of initial diagnosis• Primary site(s)• Recurrence site(s)• Other cancers
Treatment Response:• Questions about treatment
modalities (therapies/surgeries/radiation)
• Free text about treatments
Demographics:• Year of birth• Race and ethnicity
Free text about anything additional

Advocacy Partners
When I saw the delivery, I cried ~ I’m so excited to be part of this genomics project for angiosarcoma. It’s a privilege. Let patients benefit from what is learned from this research ~ Pepperrell, MA !
Like electing people to the school board who never had children, or building a retirement community without input from retired people. You have walked in our shoes by asking for our input. ~ Kernersville, NC!
I see my daughter in this research and it’s both heartbreaking and makes me proud that she wanted to be a part of the solution and give back.!~ Marlborough, MA
I didn’t choose this cancer. It chose me! And since it did, we are continuously mounting a large and dedicated war against it!~ Lansing, MI !
• A direct-to-patient approach using social media & patient/advocate partnerships enabled rapid identification of large numbers of angiosarcoma patients willing to share tumors, blood, saliva, and medical records.
• Remote acquisition and sequencing of patient samples from the USA and Canada is feasible and ongoing.
• Genomic analysis of saliva and cell free DNA from blood biopsies to study resistance, tumor evolution, and heterogeneity is underway.
• All de-identified clinically-annotated genomic data from 14 samples from 12 patients are now publicly available.
• This study may serve as a model for patient-driven research in other cancer types.• This study serves as proof of principle that direct-to-patient genomics efforts can democratize cancer
research for exceedingly rare cancers, which to date have been understudied.

Loved One Survey Data
Technology, social media, and cultural changes now provide a new opportunity
to engage cancer patients and directly partner with them in this research!
ASCproject.org enables patients in the US and Canada to participate directly in genomics research regardless of where they live!
