Task 8 : Classification of self-reported breast cancer posts on Twitter

Breast cancer patients often discontinue their long-term treatments, such as hormone therapy, increasing the risk of cancer recurrence. These discontinuations may be caused by adverse patient-centered outcomes (PCOs) due to hormonal drug side effects or other factors. PCOs are not detectable through laboratory tests and are sparsely documented in electronic health records. Thus, there is a need to explore complementary sources of information for PCOs associated with breast cancer treatments. Social media is a promising resource but extracting true PCOs from it first requires the accurate detection of self-reported breast cancer patients.  In this task, only about 26% of the tweets contains such self-reports (S) and 74% of the tweets are non-relevant (NR). Systems designed for this task need to automatically identify tweets in the self-reports category.

  • Training data: 3815 tweets
