Can digital surveys capture the full toll of rectal cancer treatment?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Adults age 18 years or older meet all of the following. 2. Documented rectal cancer diagnosis (for example, ICD-10-CM C20) without metastatic disease at the initial study eligibility assessment. 3. Established follow-up with UCSF colorectal surgery, medical oncology, or radiation oncology, generally defined as at least two encounters more than 1 month apart. 4. Active UCSF MyChart access by enrollment and ability to personally complete the electronic consent and surveys, independently or with reasonable technical or accessibility assistance that does not answer questions on the participant's behalf. Individuals identified through PRP direct mail who do not yet use MyChart may activate MyChart before enrollment. 5. Able to read and complete the currently validated English-language study materials. 6. Able to provide informed consent and HIPAA authorization. Exclusion Criteria: 1. Metastatic disease at the initial eligibility assessment. 2. Unable or unwilling to activate and personally use UCSF MyChart before enrollment, even with reasonable technical or accessibility assistance. 3. Unable to complete the English-language consent and validated instruments. This initial pilot is limited to English because validated translations and translated automated workflows are not yet available. 4. No UCSF clinical encounter for more than 6 months or otherwise lost to follow-up.- Unable or unwilling to provide informed consent and HIPAA authorization. 5. Prisoner at enrollment. If a participant becomes incarcerated or loses decision-making capacity after enrollment, active survey collection will stop. Participants who develop metastatic progression after enrollment are not treated as screen failures; they will receive one final general ABCRC module and then exit the automated survey sequence.
