Assessment of the WATChmAN (Web virtuAl Testicular CANcer Clinic): A Randomized Controlled Study to Estimate the Efficacy of an Electronic Surveillance Tool for Stage I Testicular Cancer

Patients randomized to the standard of care arm will be required to follow the active surveillance protocol created by the Multidisciplinary Testicular Cancer Clinic at Princess Margaret Hospital. This involves blood marker and CT tests at predetermined intervals for 5-9 years depending on the patient's testicular cancer diagnosis (seminoma vs. non-seminoma). If randomized to this group, participants will be required to return to the Multidisciplinary Testicular Cancer Clinic to receive the results of their surveillance testing face-to-face in a medical appointment. In addition to these surveillance testing and follow-up visits, participants will also be asked to complete surveys regarding their satisfaction with the in-person active surveillance program. These surveys will take approximately 10-15 minutes to complete and will be predominantly multiple choice. These surveys will be emailed to participants at 6 months, 1 year, 2 years and 5 years after the study begins. As per current standard of care practice, participants may choose to have their imaging completed at a centre outside of the UHN. In these cases, participants will be required to obtain and send CDs with their imaging and reports to their most responsible oncologist at Princess Margaret. Blood marker visits can be performed anywhere without sending the results to Princess Margaret.

Patients randomized to the WATChmAN group will also be required to follow the active surveillance protocol created by the Multidisciplinary Testicular Cancer Clinic at Princess Margaret Hospital. If randomized to this group, a physician from the Multidisciplinary Testicular Cancer Clinic will still review the participant's surveillance testing results but will interact with the WATChmAN platform instead of receiving their results face-to-face in a medical appointment. Specifically, if randomized to this group participants will be required to:

• Asked, but not required, to have their picture taken to be uploaded into the WATChmAN platform. Their photo will only be stored on the password-protected WATChmAN database and will serve to cue facial recognition in the physicians reviewing their results and therefore enhance recall of their personal history.
• Confirm their registration in the WATChmAN program via a welcome email
• Respond to WATChmAN generated messages and reminders requesting whether or not their upcoming surveillance testing (e.g. blood tests and/or CT imaging scans) has been completed
• Respond to WATChmAN generated messages to confirm where their upcoming testing (e.g. blood tests and/or CT imaging scans) has been completed
• Check their results on the WATChmAN platform and express any concerns/issues they might have about their treatment and/or health to their most responsible oncologist through the WATChmAN platform
• Confirm receipt of messages concerning whether they need or do not need to come in for an in-person follow up visit
• Return to the Multidisciplinary Testicular Cancer Clinic to see a physician face-to-face for a final exit follow-up appointment when their active surveillance treatment is complete
• If getting their CT imaging visits outside the UHN, obtain and send CDs with their imaging and reports to the WATChmAN research coordinator for upload into the WATChmAN system (please note: this requirement is identical for patients in the standard of care group)
• Participants do not need to send in their blood test results. Their blood marker visits can be performed anywhere without needing to send them to the WATChmAN coordinator.

Finally, in addition to these surveillance testing and WATChmAN interactions, participants will also be asked to complete surveys regarding their satisfaction with their virtual active surveillance program. These surveys will take approximately 10-15 minutes to complete and will be predominantly multiple choice. These surveys will be emailed to participants at 6 months, 1 year, 2 years and 5 years after the study begins.

It is predicted that the WATChmAN virtual platform will take at least one year to construct; however, the researchers involved in this study believe there is value in launching this virtual clinic without delay. This will also allow further improvements to the design of the WATChmAN platform as it is being built. Therefore, this study will be divided into two stages:
