Clinical Trial Summary

Female breast cancer is the most common cancer and fifth leading cause of cancer death worldwide. In the past decade, breast cancer consistently to be the most common cancer for women in Hong Kong, so much that it accounts for 27% of all female cancers, with 4,600 new cases of breast cancer registration every year and the lifetime breast cancer risk for females is 1 in every 14. At the same time, breast cancer ranks the third in cancer death in Hong Kong, with a five-year relative survival rate of 84%. Regular mammography screening has been shown to reduce the mortality of breast cancer. International guidelines recommend annual or biannual mammography screening for women aged 50 or above. The adherence to regular mammography screening remains a challenge. Studies had shown that the adherence decreased over time. Mailed and telephone reminder were being proven to be effective tools to increase the adherence to regular breast screening using mammography. However, both mailing and telephone strategies are associated with labor intensity and high cost. Over the past two decades, the advent of internet and smartphone provided a fertile platform for the development of mobile-health technologies. WhatsApp Messenger is one of the most frequently used free-of-charge mobile messenger that permits users to send secure messages across different device platforms. A recent randomized controlled trial from our team has suggested its clinical utility in improving adherence to regular colorectal cancer screening using fecal immunochemical test. This encouraging data prompted us to investigate the potential role of WhatsApp Messenger in breast cancer screening. We hypothesized that text reminder sent via WhatsApp Messenger improves the longitudinal adherence to biannual mammography in a community-based, opportunistic breast screening program.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
