Tradeoffs in Patient Decision Making About Rectal Cancer Treatment: Benefits Compared to Quality Of Life.

Study Overview
=================
Brief Summary
-----------------
This study is aiming to look into patients' treatment preferences and their socio economic background as well as the exploration of thought processes leading to these preferences. It will integrate, in two exploratory questionnaires, the three most common treatment schema (standard of care, non-operative management, surgery alone) all of which have been demonstrated efficacious.

Detailed Description
-----------------
The primary study objective is to evaluate socioeconomic and demographic factors involved in patients' / physicians treatment preferences. The secondary objective is to assess the tradeoff level between the benefits versus quality of life. This study will evaluate 192 participants: 14 physicians (group A) and 178 patients (group B). Participants with operable rectal cancer or health professionals will be screened for eligibility. Subsequently, these participants will be offered to participate in this pilot study and provided a consent form. When a participant has consented to participate, he/she will be provided with a first questionnaire (socio-demographic characteristics, some clinical data and medical baseline information as well as details about their current knowledge about treatments). An informational brochure will be given after answering the first questionnaire describing different treatment regimens, treatment duration, potential side effects and oncologic outcomes. A second questionnaire will be provided (evaluating patients treatment preferences and tradeoff). The consent form, brochure and questionnaires will be available only in an electronic format (Microsoft Form).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Group A: Patients<br>Recruitment for this group will take place at either the radiation-oncology department or at the colorectal surgery department, at the time of consultation or at the time of diagnosis, before the treatment setting. Once clinical staging is available, the surgeon and/or radiation-oncologist and/or research assistant should identify eligible patients. Patients that comply with selection criteria (inclusion/exclusion) will be approached by a research team member. For those patients interested in participating, the e-link to the consent form for this group will be sent by email. Once a patient decides to sign the consent form, the link for the questionnaire Q1 will be sent by email. | Behavioral: The only intervention will be the information brochure that will be given after the first questionnaire.<br>* The information brochure will be given to both groups at the same time at 2-3 weeks after the first consultation (patients group) or after answering the first questionnaire (physicians group).<br>|
| Group B: Physicians<br>Health professionals will be approached by the research team. The study aim will be explained, and participants that agree to participate will be provided an e-link to consent for this group. Once the health care participant decides to sign the consent form, the link for the questionnaire Q1 will be sent by email. | Behavioral: The only intervention will be the information brochure that will be given after the first questionnaire.<br>* The information brochure will be given to both groups at the same time at 2-3 weeks after the first consultation (patients group) or after answering the first questionnaire (physicians group).<br>|
