Canary Center at Stanford, Cancer Research UK, and the OHSU Knight Cancer Institute, hosted the Early Detection of Cancer Conference September 24 – 26 at the Frances C. Arrillaga Alumni Center, Stanford, California. Approximately 370 attendees, from 120 institutions, and 11 countries outside of the USA (including Australia, Canada, China, Finland, France, Great Britain, India, Netherlands, South Korea, Switzerland, and Ukraine) brought forth their latest findings and ideas. The annual Conference brings together experts in early detection from multiple disciplines to share ground breaking research and progress in the field.
The conference is part of a long-term commitment to invest in early detection research, to understand the biology behind early stage cancers, find new detection and screening methods, and enhance uptake and accuracy of screening.
The talks ventured widely, from finding ways to extract more information from cell-free DNA in blood, to building cohorts of people at high risk of cancer to prospectively study the emergence of disease, to the role of the tumor micro-environment and the immune system in cancer early detection, and going beyond traditional risk factors to better select populations for targeted cancer screening.

What if we could view changes in the body earlier than early to warn of possible disease? That is the aim of Project Baseline, to map human health. The New York Times published “Project Baseline Aims to Ward Off Illness Before We Get Sick” by Anahad O’Connor (Oct 2018). The study is recruiting 10,000 adults. And each will be examined and followed for at least four years. So the goal is to discover the earliest warning signs of cancer, heart disease and other killers. Participants, the first of whom was enrolled in 2017, are called Baseline Explorers.
Project Baseline is the result of conversations in 2013, led by Google X’s Andrew Conrad. He consulted with Dr. Sam Gambhir, MD, chair of Radiology at Stanford University and director of the Canary Center for Cancer Early Detection. And also with Robert M. Califf, MD, professor of Cardiology in the School of Medicine, Duke University.
Conrad (now CEO of Verily, a spin out of Google X) was interested in exploring with these two notable healthcare thought leaders, one in cancer and the other in cardiology, about how to create what has become a landmark study. Both had deep experience in working with large patient cohorts and focus on early detection of disease. The project has formed teams across the country.
Seeking to create a baseline of health
Traditional trials focus on those who have a disease. So Project Baseline, as the name implies, mainly enrolls healthy individuals gathering enormous amounts of information. Baseline equips enrollees with wearable technology from Verily that tracks sleep patterns, heart rhythms and physical activity. The team is developing tools and technologies to collect, organize, analyze and curate the data.
And investigators are determining the best ways to share data with participants that is helpful to them. They are looking at how they can engage with their medical professionals.
Canary Foundation and the Canary Center at Stanford for Cancer Early Detection
Dr. Gambhir has served as Canary Foundation’s scientific director for more than a decade. He led the development of the Canary Center at Stanford for Cancer Early Detection. The Canary Center is a partnership forged in 2008 between Stanford University and Canary Foundation under the leadership of Don Listwin, based on the foundation’s mission. And interesting to know, Canary Center is the first program Stanford has focused entirely on cancer early detection.
American Cancer Society Report January 2019 is hopeful. Yet it motivates us to work harder at finding better tests
January 16, 2019
The new American Cancer Society report shows us that cancer deaths have dropped by 27% since their peak in 1991. The decrease is attributed to early detection, better treatments and a reduction in smoking rates. The ACS report also points to a socio-economic disparity in the numbers, based on broad county and area reports collected by Surveillance, Epidemiology, and End Results (SEER – a National Cancer Institute source of epidemiologic information on the incidence and survival rates of cancer in the United States, where access to education and healthcare remains a problem. Additionally, lower incidence has been slower in cancers such as lung and prostate. Also, rates of new cases rose for pancreatic and other cancers. While the overall decline in rates is great news, we must keep up the momentum to create early detection tests to save lives as cancer remains the second cause of death in the United States (22% in 2016), and a major health issue worldwide.
The report states that in 2019, 1,762,450 new cancer cases and 606,880 cancer deaths are projected to occur in the United States. From the report: “…the Lifetime probability of being diagnosed with invasive cancer is 39.3 % for men and 37.7% for women. Prostate, lung and colorectal cancers (CRCs) account for 42% of all cases in men, with prostate cancer alone accounting for nearly 1 in 5 new diagnoses. For women, the 3 most common cancers are breast, lung, and colorectum, which collectively represent one-half of all new diagnoses; breast cancer alone accounts for 30% of all new cancer diagnoses in women. The reasons for the excess overall risk in men are not fully understood, but partly reflect differences in environmental exposures, endogenous hormones, and probably complex interactions between these influences.”
Canary Foundation has been on the forefront of stimulating the field of cancer early detection globally by demonstrating cancer early detection tests as well as hosting scientific symposiums, mentoring researchers choosing the early detection path, and forging important national and international partnerships. To address access problems, Canary’s investments have focused, when possible, on cost-effective tests as a path to bridging the socio-economic disparities. Examples can be found in are our funded studies in enhance ultrasound using microbubbles, where ultrasound is found in doctor’s offices worldwide, representing an imaging modality in development useful for multiple cancers that is low-cost, non- invasive and with the additional benefit of not using radiation.
Canary funds four collaborative studies that pair faculty at Stanford with faculty at the University of Cambridge
February 15, 2018
Canary Foundation was ahead of the cancer early detection wave when it started in 2004. Since then, academic institutions, such as the University of Cambridge in the UK and the University of Calgary in Canada, have looked to Canary for advice as they build out their own cancer early detection programs.
This year, one such collaboration is taking shape in dynamic ways. Canary’s partnership with the University of Cambridge has resulted in four promising studies that partner researchers from Cambridge with researchers from Stanford. These projects, jointly funded by Canary Foundation and the Cancer Research UK Cambridge Centre, will explore innovative ways to detect prostate, lung, esophageal and renal cancers at an early stage.
In order to receive seed grants for these projects, applications had to include faculty at both Stanford and Cambridge. By fostering this transatlantic collaboration, Canary hopes to bring outstanding academic and clinical researchers from the US and UK together to tackle some of the most challenging questions in detecting cancer sooner.
The awards were announced at Cambridge’s third annual early detection symposium on January 15. You can read more about these collaborations below or by watching the video.
“A multi-modal approach to discover novel blood-based biomarkers for early detection of poor prognosis prostate cancer”
Tanya Stoyanova, an assistant professor of radiology at the Canary Center, is partnering with Vincent Gnanpragasam, an urologist at Cambridge University Hospitals, to identify different types of tumors in men with prostate cancer. The goal is to distinguish between aggressive tumors that would require immediate treatment, and slow-growing tumors that may not need treatment immediately but could be monitored closely so that any changes in the tumor can be picked up and acted upon. Their project will use data from a number of sources including tumor DNA found circulating in the blood, protein molecules found in cancer cells, and MRI imaging of the tumor.
“Early cancer detection through transcriptomic analysis of host immune cells”
Tom Soh, a professor of radiology at the Canary Center, is exploring new ways to detect early-stage lung cancer through his partnership with Robert Rintoul, a thoracic consultant at Cambridge University Hospitals. The pair is studying the immune cells in blood samples to see if there are particular signals that could be used to identify lung cancer early.
“Levitating a sponge for the early detection of Esophageal Adenocarcinoma”
Utkan Demirci, a professor of radiology at the Canary Center, is working with Rebecca Fitzgerald, Cambridge’s early detection program co-lead, to detect early signs of esophageal cancer. They will use a new nanotechnology developed by Demirci that separates different types of cells using a magnetic field. The technology will be applied to the mixture of cells collected from patients that are given a Cytosponge test developed by Fitzgerald that can diagnose Barrett’s esophagus – a common condition that, in some cases, develops into esophageal cancer.
“Early detection of renal cell carcinoma using DNA methylation markers in urine”
Olivier Gevaert, an assistant professor of medicine and of biomedical data science at Stanford, and John Leppert, an associate professor of urology at Stanford, are teaming up with Charlie Massie, a group leader in Cambridge’s early detection program. They will study whether it is possible to detect the early stages of a type of kidney cancer (Renal Cell Carcinoma) using biomarkers found in urine. Their research will look at specific signals in the DNA cells called methylation.
Lung Cancer Biomarker Discovered by Canary Researchers Attracts New Interest From Academia and Industry

Team lead Dr. Samir Hanash discusses biomarker SFTPB’s journey from discovery to commercialization
Searching for a needle in a haystack. That’s how Dr. Samir Hanash described the long, intensive process of finding a blood-based biomarker to detect lung cancer. So, when the Canary Lung Cancer Team, with Hanash at the helm, discovered a promising candidate called pro surfactant protein b (SFTPB), the potential impact was tremendous, especially since there has been only one other similar discovery to date.
Early validation studies of SFTPB have been so promising that multiple parties – among them The University of Texas MD Anderson Cancer Center and tech startup MagArray – have entered into negotiations with Canary Foundation to do further testing.
As part of a comprehensive lung cancer screening process, SFTPB has the potential to address shortcomings like false positives on CT scans as well as more accurately identify who should be screened and predict how frequently the person should be monitored.
Dr. Hanash recently discussed the discovery of biomarker SFTPB and its potential in a conversation with Canary Foundation that can be read below.
Canary Foundation: Can you explain the current state of lung cancer screening and why it is important to add biomarkers into the process?
Dr. Samir Hanash: The uptake of lung cancer screening with low dose CT has been quite modest in the U.S. and not at all in European countries. Blood-based biomarkers to determine the need for CT would represent a paradigm shift.
CF: When did your search for a lung blood biomarker begin?
SH: It began more than 15 years ago when I was at the University of Michigan.
CF: What makes it so difficult to pinpoint promising lung cancer biomarkers?
SH: Tremendous disease heterogeneity (diversity), limited availability of most informative samples for early detection, the need for in-depth high sensitivity methodology to find the needle in the haystack.
CF: At what point in the process did SFTPB emerge as a potential biomarker candidate?
SH: It emerged when we integrated data from mouse models of lung cancer with human data and lung cancer cell line data.
CF: What qualities does SFTPB have that led you to focus on it?
SH: We have subjected it to a multitude of blinded validation studies, and it came out significant for discriminating between lung cancer and controls.
CF: Validation studies of SFTPB have been very promising. What do these studies reveal in terms of the biomarker’s potential?
SH: That as part of a broader panel of biomarkers for lung cancer, it can be an effective tool for lung cancer screening.
CF: Now other groups are interested in further testing SFTPB and Canary Foundation has developed a licensing agreement to facilitate this. Why is additional testing necessary and what are the potential outcomes?
SH: There are many clinical indications related to lung cancer for which SFTPB may or may not be useful.
CF: If further studies of SFTPB continue to produce promising results, what are the next steps? How long could it be before SFTPB is used in lung cancer screening?
SH: That depends on performance in the most rigorous validation studies that meet FDA requirements.
Samir M. Hanash, M.D., Ph.D., is a professor in the Department of Clinical Cancer Prevention at The University of Texas MD Anderson Cancer Center in Houston. We thank him for his insights.

The beginning of the year presents a cue to reflect on the successes of the previous year, and look forward to goals for the coming months. We’re delighted to announce progress with our research that has tremendous implications for future innovations, as well as our ambitions for the Canary Challenge 2014.
New technologies always evoke excitement and anticipation. Here at Canary, if a scientist wants to use a new technology to advance or improve the ways we detect cancer tumors early, we are all for it. Enhanced ultrasound using microbubble technology is one of these technologies.
This technology will change the way doctors view tumors. Microbubbles are miniature gas bubbles, mostly containing oxygen or air, which can be uniformly suspended in a liquid such as blood. Due to their size, they can pass through even the smallest of blood vessels and therefore are commonly used together with medical ultrasound imaging. As effective vehicles for highlighting blood in ultrasound images, Canary scientists use microbubbles as a contrast agent to view cancer tumors. Our clinical trials in Rome with women who have ovarian cancer have produced great results. Here in the US, we anticipate replicating microbubble technology for applications with breast cancer, prostate and pancreatic cancer.
We also value and actively seek out key partnerships, whether academic or industry. Soon we’ll announce a partnership with Genomic Health Inc. in the area of prostate cancer. We’re in talks with MD Anderson in Houston to help with coordinating a national multi-institutional lung cancer study.
We have great plans for our largest fundraising event, the Canary Challenge, which is about to get bigger and better than ever. Mark your calendar now for September 27, 2014. Register now for $25 until March 31. The event will be hosted at HP’s campus in Palo Alto on Hanover St. We’re aiming high this year with a goal of raising $1.5 million, recruiting 150 teams and over 1,500 riders. This year’s ride will benefit the Canary Center at Stanford, supporting the researchers, scientists and doctors who are dedicated to cancer early detection. Come be a part of an amazing one-day cycling event!
We’re pleased to announce that we will again be partnering with women’s pro cycling team extraordinaire, the Vanderkittens, who will host monthly training rides for Canary Challenge riders. Hani Juha, a cyclist and great coach, of Menlo Bike Club will also offer weekly training rides, an annual training program, as well as monthly clinics. We invite anyone and everyone in the Canary community to take advantage of these tailored experiences to brush up on their skills in time for the event.
What are your hopes and dreams for cancer early detection research at Canary Foundation? Let us know in the comments below!

Photo: The clinical trial coordinators for the Canary Prostate Active Surveillance Study (PASS) accept the 2013 Canary Award on behalf of the Canary Prostate Team.
Dr. Dianne Miller was presented with the award for her team’s success in promoting adoption of ovarian cancer prevention programs throughout the Canadian province of British Columbia. Because lethal ovarian cancer often originates in fallopian tubes, their removal can prevent the development of ovarian cancer, potentially reducing the incidence by 50% or more. Since the advent of the British Columbia educational campaign in September 2010, clinics across the province have seen a practice shift toward removal of fallopian tubes during common gynecological surgeries (such as hysterectomy and tubal ligation), thanks to the efforts of Dr. Miller’s team.
The Canary Prostate team was presented with the Canary Award for the team’s success in meeting or exceeding all of its major milestones in the Prostate Active Surveillance Study (PASS) clinical trial. Earlier in the month of October, 2013, the PASS trial celebrated reaching another major milestone, as the 1,000th participant was enrolled in the trial. The trial’s goal is to manage low-risk prostate cancer through active surveillance while identifying markers to distinguish non-aggressive prostate cancer from potentially lethal disease.
Congratulations to both teams for all their hard work, and to all the Canary teams who work tirelessly to develop research and solutions to make accessible cancer early detection a reality.

In the United States, it is estimated that there will be 232,340 new breast cancer cases and 39,620 breast cancer mortalities in 2013. 1 in 8 women will be diagnosed with breast cancer during their lifetime. Despite the widespread use of mammography, the technology is limited as many cancers are missed and conversely many women undergo biopsies and surgeries of benign or non-aggressive tumors.
Canary Foundation is supporting a Breast Cancer Early Detection Initiative focused on finding blood-based and imaging biomarkers to improve the current state of breast cancer early detection. The vision of the blood work is to distinguish women with benign versus malignant tumors, and to identify the aggressive, hard to detect, breast cancers. The vision of the imaging work is to detect breast cancer at the earliest stages, when the tumors are very small.
Canary is committed to funding safe, efficient, cost effective tests for cancer early detection.
