About

The ONCOFOOD project aims to design and develop new innovative food solutions for cancer patients, taking into account not only their nutritional requirements but also their sensory changes, promoting eating pleasure and preventing malnutrition. Research involving cancer patients but also their families and health care professionals is a key element of this approach to ensure the success of the developed products for the target group.

Full description

The study will be divided into three stages: in Stage 1, individual interviews will be conducted with present and past cancer patients, focus groups with families/care givers of cancer patients and health care professionals (cancer specialist nurses, clinical and medical oncologists, speech and language therapists, dietitians, oncology social workers and counselors). The interviews will help collect data and gain understanding on the needs of cancer patients, barriers to current food proposals and expectations from new solutions. In subsequent stages, semi-quantitative studies will be conducted with cancer patients that require texture-modified foods (Stage 2) and patients with taste & smell alterations (Stage 3). Patients will be required to evaluate texture-modified products (developed using 3D food printing technology) and taste-optimised products (i.e. soups, mousses, fruit and vegetable beverages, dairy desserts and seasonings) developed based on the results obtained from Stage 1 above.

88 participants in 3 patient groups

Stage 1: Interviews and focus group sessions

No Intervention group

Description:

Group A: Cancer patients (requiring or have required texture-modified foods and/or experiencing or have experienced taste\&smell alterations in the last 12 months) will be required to attend a one-hour online interview. Group B: Relatives of cancer patients (requiring texture-modified foods and/or experiencing taste\&smell alterations) will be required to attend a 2-hour online focus group session. Group C: Healthcare professionals with a minimum of a year's experience with oncological patients that require texture-modified foods and/or have taste \& smell alteration will be required to attend a 2-hour online focus group session. A food diary will be given to Group A and B to complete for 7-days prior to their session. Topics to be discussed during the interview and the focus group sessions will include the food requirements of cancer patients, the barriers of the current food products, possible solutions to these requirements if any and their expectations towards new food solutions.

Stage 2: Texture-modified foods for cancer patients

Experimental group

Description:

The study will involve conducting a tasting trial over a 2-weeks period where participants will be required to consume a maximum of three 3D printed texture-modified food based on the findings from Stage 1 and evaluate the food product by completing a structured questionnaire. Key questions areas covered by the questionnaire include appetite, sensory characteristics of the product (taste, flavour, mouthfeel/texture and smell), liking and acceptability, purchase intent and best place to buy the products; questions will involve rating scales as well as qualitative comments.

Treatment:

Behavioral: Texture-modified foods for cancer patients (Stage 2)

Stage 3: Taste-optimised foods for cancer patients

Experimental group

Description:

The study will involve conducting a home test over a one-month period where participants will be required to consume taste-optimised products based on the findings from Stage 1 and evaluate the food product by completing a structured questionnaire. Key questions areas covered by the questionnaire include appetite, sensory characteristics of the product (taste, flavour, mouthfeel/texture and smell), liking and acceptability, purchase intent and best place to buy the products; questions will involve rating scales as well as qualitative comments.

Treatment:

Behavioral: Taste-optimised foods for cancer patients (Stage 3)
