Most patients who have pelvic radiotherapy (RT) as a treatment for cancer experience some degree of acute gastrointestinal (GI) and genitourinary (GU) toxicities. If physicians can anticipate, identify, and correctly manage symptoms, they can significantly improve patients' quality of life (QoL). Our study plans to enroll patients receiving standard or hypo-fractionated curative pelvic RT for the first time at the MUHC Radiation Oncology clinic. Patients will complete, through a mobile application (Opal) and in real-time, electronic patient-reported outcomes (PROs) questionnaires about acute GI/GU toxicities and quality of life (QoL). The treating physician will fill in the traditional intra-treatment forms simultaneously. The project's overall goal is to provide intra-treatment assessment tools to collect clinical information more relevant to the patients, improve patients' QoL, and triage clinically significant toxicities more efficiently.
