The goal of this Randomized Controlled Trial is to compare the effectiveness of radiotherapy-specific, physician-led educational videos introduced before the initial Radiation Therapy consultation .
The primary objective is to assess the impact on patient-reported knowledge of RT, with secondary objectives including assessment of patient-reported anxiety and satisfaction with the educational process.
Patients will be randomly assigned to two groups.
1. Video Group - Patients will receive a WhatsApp message containing the educational video prior to their consultation. 2. Verbal Instruction Group - Patients will receive standard verbal education from a radiation oncologist during their consultation.
The participants will fill Pre and post intervention questionnaire forms
Diagnosed with cancer and scheduled for radiation therapy at Tomotherapy unit of Cyber knife and Tomotherapy Centre of JPMC.
Fluent in Urdu.
No prior experience with radiation therapy.

Radiotherapy-Specific Educational Video
BehavioralThis intervention consists of a radiotherapy-specific, physician-led educational video delivered prior to the first radiation oncology consultation. The video was locally developed, filmed within the actual CyberKnife and Tomotherapy facility, and features real radiation oncologists, residents, and departmental staff familiar to patients. It demonstrates real simulation rooms, immobilization devices, and treatment machines that patients will encounter during their care. The video is 3.5 minutes in duration, delivered in Urdu, the native language of the study population, and specifically designed for radiation therapy-naïve patients in a lower-middle-income country setting. Content includes an overview of radiation therapy, simulation procedures, treatment delivery, common side effects, and post-treatment follow-up.
''Change in Patient-Reported Understanding of Radiation Therapy Between Pre- and Post-Consultation Assessments''
The primary outcome of this study is the change in patient-reported knowledge and understanding of radiation therapy (RT) following exposure to educational intervention. This outcome is measured by comparing pre- and post-consultation knowledge and understanding scores between the two study arms (video education vs. verbal instruction) using a self-administered 5-point Likert questionnaire (1 = very poor, 5 = excellent). Higher scores indicate better understanding. Anxiety is measured on a 10-point Visual Analog Scale (0 = no anxiety, 10 = maximum), with higher scores indicating worse anxiety. The questionnaire evaluates patient understanding across key domains of the radiation therapy process, including RT purpose and goals, simulation and immobilization, treatment delivery, expected side effects, and follow-up. The primary endpoint is the mean change in composite knowledge score from baseline to post-consultation, with greater improvement indicating better understanding.
