Study Evaluating the Efficacy of the myDIET Software Tool in the Nutritional Management of Patients With Localized and Resectable Gastric or Esogastric Junction Cancer. (MyDIET)

Evaluation of the Efficacy of the myDIET Software Tool in the Nutritional Management of Patients With Localized and Resectable Gastric or Esogastric Junction Cancer.

This is a prospective, single-center, single-arm Phase II study evaluating the efficacy of the myDIET software tool in the nutritional management of patients with localized and resectable esogastric junction cancer.

Study Overview

• Status: Recruiting
• Conditions: Gastric Cancer; Oesogastric Junction Cancer
• Intervention / Treatment: Other: myDIET software tool

Detailed Description

Gastric cancer is the 3rd leading cause of cancer mortality worldwide, with a 5-year survival rate of less than 30%. In localised gastric cancer (GC) or cancer of the oesogastric junction (OGJ), the standard treatment consists of gastrectomy and peri-operative FLOT-based chemotherapy (5FU, Leucovorin, Oxaliplatin, Taxotere). However, up to 51% of patients have post-operative complications, and only 60% can benefit from post-operative chemotherapy (at least one course) initiated within 12 weeks of surgery, while 46% receive the full theoretical regimen.

An incomplete adjuvant chemotherapy regimen drastically reduces post-operative prognosis. Undernutrition and sarcopenia increase the occurrence of post-operative complications, length of stay and post-operative readmissions. Undernutrition is an independent risk factor for failure and/or incomplete adjuvant chemotherapy, with an impact on progression-free survival and overall survival. There is a high prevalence of undernutrition in patients with GC/OGJ, estimated at 53-60%, and the proportion of undernourished patients increases significantly postoperatively compared with preoperatively.

Preoperative nutrition and physical activity in sarcopenic patients has been shown to reduce postoperative complications. Early multimodal management, combining nutrition, adapted physical activity and neoadjuvant chemotherapy, is therefore recommended and essential in the perioperative situation. To optimise the nutritional management of patients with operable gastric or oesogastric junction cancer, the CLB teams have developed a computer interface (MyDIET) linked to the myCLB patient portal. This provides semi-personalised monitoring based on self-questionnaires designed to assess and educate patients or their carers about nutritional issues from the outset of oncology treatment, and to prevent the onset or worsening of undernutrition.

For this reason, the sponsor proposes an exploratory study to assess the efficacy of the myDIET digital tool in increasing the proportion of patients with localised CG/OGJ initially treated with neo-adjuvant chemotherapy and who undergo surgery and are able to receive adjuvant chemotherapy within 8 weeks post-operatively.

Participant Group / Arm

Intervention / Treatment

Experimental: use of myDIET tool for nutritional management; Patients will be followed up at regular intervals during neoadjuvant treatment, perioperatively and up to 6 months after the date of surgery (after completion of postoperative treatment).

Other: myDIET software tool; The tool is based on self-questionnaires completed by the patient. They are mainly filled in using visual analogue scales (from 0-10) or grades of symptoms/toxicities (Grades 0 to 4), based on the CTCAE V5. These scales will cover the following themes: food intake, weight changes, digestive symptoms, taste disorders, pain and fatigue. The system will be able to monitor data changes and the response given will be adapted according to the severity of symptoms: No signs of seriousness: general prevention or treatment documents/advice: toxicity management, nutritional advices targeted on symptoms, on digestive problems, on appropriate physical activity.; Presence of signs of seriousness: action to be taken and alert to the coordinating nurse, oncologist or dietician. In case of an alert, the coordinating nurse will call the patient back and either manage the symptom, schedule a nutritional consultation to initiate nutritional management, or refer the patient to the oncologist.
