CANcer TOxicities Study (CANTO)
The CANTO study is a French prospective cohort study investigating long-term treatment-related toxicities in women with localised breast cancer, with over 12,000 participants enrolled across 26 cancer centers in France by October 2018. Recruitment began in 2012, with participants enrolled at the time of diagnosis through their treating cancer centres. The study also includes embedded biological sub-studies (e.g., microbiotic and cognitive). Follow-up assessments occur at diagnosis, 3–6 months, and then at 12, 36, and 60 months after completion of primary treatment. Long-term follow-up is collected at 6, 7, 8 and 10 years.
