This study aims at investigating behaviors of cancer patient regarding complementary and alternative medicine (CAM) with mixed methodology. The investigators want to realize a pilot study evaluating patient's use and attitude with particular focus on natural products (phyto- and aromatherapy). They aim at giving an overview of their actual consumption (and not to promote natural products) in order to (1) prioritize needs regarding integrative care to promote quality of life and survivorship; (2) identify potential short- or medium-term safety issues for patients; and (3) propose adequate pharmaceutical council.
Studied period (years): 2026, approximately 9 months
Objectives:
The study has three complementary objectives:
Primary objective (quantitative):
To descriptively quantify the use of complementary and alternative medicine (CAM) among cancer patients treated at Institut Jules Bordet and to identify patient-reported needs and information sources.
Secondary objective (interventional mixed-methods) :
To explore patient behaviors, perceptions and expectations regarding CAM use through questionnaires and semi-structured focus groups, including perceptions related to treatment adherence and survivorship experience. In addition, a structured medication review will be conducted for all participants in the focus group phase in order to identify and describe drug-related problems, including potential interactions between conventional treatments and herbal products.
Operational objective :
To support the prioritization and development of integrative oncology and survivorship programs within the ONCO.CARE and CAIROS projects.
Hypotheses:
No formal hypothesis testing is planned. This is an exploratory, descriptive study.
Study Design (Treatment Schema):
Prospective, single-center, two-phase study:

The trial is designed in two phases, not in two arms. The "Arms and Interventions" page does not make it possible to register for two phases, hence we listed it in two arms. The first phase is a quantitative trial (questionnaire, 500 participants); the second phase is a mixed-methods qualitative-quantitative trial (see protocol design).
Phase 1 - quantitative survey : Minimum 500 patients. A survey will be completed by cancer patients over a three-month period to assess their use of complementary and alternative medicine (CAM). A survey will be made available to cancer patients over a three-month period to assess their use of complementary and alternative medicine (CAM). The questionnaire will be accessible through non-intrusive methods, including dissemination via healthcare professionals, display of study information and QR codes on hospital screens or in waiting areas, and access via a secure online link (REDCap). The survey will be available in both paper format and online via QR code (REDCap). The paper versions of the survey will be collected in a dedicated box at the entrance of the Bordet building. The questionnaire is fully anonymous, and no directly identifiable personal data will be collected.
Phase 2 - Interventional mixed-methods evaluation of cancer patient's behaviour regarding CAMs : patients (men and women) after acute phase of anti-cancer treatment. This study will include a total of 6 to 8 focus groups, with each group consisting of 5 to 10 participants. So, in total, we expect 30 to 60 participants. Participants in this arm will take part in semi-structured focus group sessions exploring their knowledge, use, motivations, perceived benefits and risks, sources of information, and expectations regarding CAM in cancer care and survivorship. Before and after the session, participants will complete anonymous questionnaires. Focus groups will last approximately two hours, include up to eight participants, and may use interactive tools to facilitate discussion. Sessions will be audio-recorded with consent, transcribed verbatim, and analyzed using rapid qualitative methods. A structured medication review based on self-reported treat
