This clinical trial is focused on studying a type of cancer called gastric and gastroesophageal junction adenocarcinoma, which affects the stomach and the area where the stomach meets the esophagus. The study is investigating a treatment approach that combines a special procedure called HIPEC (Hyperthermic Intraperitoneal Chemotherapy) with a chemotherapy regimen known as FLOT. FLOT is a combination of four drugs: oxaliplatin, docetaxel, fluorouracil, and calcium folinate. The trial aims to compare the effectiveness of using HIPEC with FLOT against using FLOT alone in patients who have a resectable form of this cancer, meaning the cancer can be surgically removed.
The purpose of the study is to see if adding HIPEC to the FLOT treatment can improve the time patients live without the cancer coming back or getting worse, which is known as progression-free survival. Participants in the study will receive either the combination of HIPEC and FLOT or just FLOT alone. The treatment will be given over a period of time, and patients will be monitored to see how well they respond to the treatment and how it affects their quality of life. The study will also look at the overall survival of patients, which is the time from the start of the study until death from any cause.
Throughout the study, patients will undergo regular assessments to check the status of their cancer and their overall health. These assessments may include imaging tests like MRI or CT scans to look for any signs of cancer progression. The study will also track any side effects or complications that may arise from the treatment. The goal is to gather information that could help improve treatment strategies for this type of cancer in the future.
