Terry Fox research team's model for detecting lung cancer saves lives, is a world leader

Vancouver, BC - A pan-Canadian team of cancer researchers has developed a predictive model for detecting early-stage lung cancer in high-risk individuals with significantly greater accuracy than other leading models. This Terry Fox Research Institute study suggests the team's innovative approach could be considered for use in lung cancer screening programs both in Canada and around the world.

The results, highlighted in a study published in the Oct. 18th edition of The Lancet Oncology, were presented at the 18th World Conference on Lung Cancer in Yokohama, Japan on Wednesday by co-principal investigator Dr. Stephen Lam (chair of British Columbia's Provincial Lung Tumour Group at the BC Cancer Agency and a professor of medicine at the University of British Columbia).

"We knew our Pan Can Lung Cancer Risk Prediction Model would probably work better than other models, but we were surprised at how much better," says Dr. Lam. "We have the means to identify high-risk people, and we know we can find cancer early. This model provides a superior tool that would be beneficial in Canada and around the world in saving more lives."

The Pan Can Lung Cancer Risk Prediction Model - which is used to determine which individual should undergo annual CT screening to detect early-stage lung cancer - outperformed comparable models such as The National Lung Screening Trial (led by the National Cancer Institute in the US). The Pan Can Model was developed with $8.4-million support from the Terry Fox Research Institute (TFRI), and The Canadian Partnership Against Cancer. Ottawa resident Debi Lascelle took part in the Terry Fox Research Institute study, and credits the early-detection protocol with catching her cancer while it was still curable. "Being involved in this study quite literally saved my life," said Lascelle, who had a 13-milimetre tumour removed from her right lung through surgery and has been cancer-free ever since. "How do you adequately find a way to say, 'Thank you for my life'? It's been seven years and I still haven't found a way."

The PanCan Model diagnosed lung cancer in 6.5 per cent of people screened with a follow-up of five years, compared to the four per cent of cases found by the National Lung Screening Trial over a longer term (6.5 years). Further, 77 per cent of the lung tumours diagnosed with the Pan Can Model were caught in early-stages when the cancer is potentially curable, compared to 57 per cent in the NLST study. Lung cancer is the most common cause of cancer death around the world - yet if caught early enough it can be cured in 70 per cent of cases, making early detection a critical feature in a predictive model.
