Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the symptoms of patients who have a MIPG to the symptoms of patients who have a MITG.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Objective:

Delineate the short-term appetite of patients who undergo minimally-invasive proximal gastrectomy (MIPG) and compare them with those of patients with gastric and gastroesophageal adenocarcinoma who undergo total gastrectomy (MITG). We hypothesize that MIPG is associated with better postoperative appetite levels compared to MITG, which would result in improved nutritional status and maintained body weight after surgery.

Secondary Objective:

\- Assess patient-reported outcomes (PROs) and nutrition measures. We will use the MD Anderson Symptom Inventory Gastrointestinal Cancer Module (MDASI-GI) questionnaire with additional three experimental question items ("PRO questionnaire") to collect preoperative and postoperative patient-reported outcomes (PROs) of QoL and check fasting ghrelin levels to correlate them with reported appetite levels. We will also retrospectively investigate factors associated with improved QoL after surgery, safety of MIPG and MITG, and oncological outcomes after MIPG and MITG.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard of Care

questionnaire within 30 days before your surgery and then at 1, 3, 6, and 12 months after surgery.

The questionnaire will ask about your health, appetite, and quality of life. It should take about 3-5 minutes to complete.

Standard of Care

Intervention Type OTHER

complete a questionnaire within 30 days before your surgery and then at 1, 3, 6, and 12 months after surgery

Control group

questionnaire within 30 days before your surgery and then at 1, 3, 6, and 12 months after surgery.

The questionnaire will ask about your health, appetite, and quality of life. It should take about 3-5 minutes to complete.

Control Group

Intervention Type OTHER

complete a questionnaire within 30 days before your surgery and then at 1, 3, 6, and 12 months after surgery
