What this trial studies

This study investigates how omega-3 fish oil fat emulsion impacts immune function and recovery in patients undergoing radical surgery combined with intraperitoneal hyperthermic infusion chemotherapy for locally advanced gastric cancer. It aims to evaluate changes in immune markers, complications, length of hospital stay, and overall costs associated with hospitalization. Participants will have their baseline data collected and analyzed to determine the efficacy of the omega-3 intervention using statistical software.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with locally advanced gastric cancer who meet specific staging criteria and have no prior history of gastric surgery or other malignancies.

Not a fit: Patients who have undergone prior chemotherapy or radiotherapy, or those with contraindications to surgery, may not benefit from this study.

Why it matters

Potential benefit: If successful, this could enhance recovery and immune function in patients after surgery, potentially reducing complications and healthcare costs.

How similar studies have performed: While the use of omega-3 fatty acids in cancer care is explored, this specific approach combining it with hyperthermic chemotherapy is relatively novel and not extensively tested.

* Use of immunosuppressants such as hormones within 3 months before treatment.
* Preoperative anemia (hemoglobin \< 90g/L) and severe hypoalbuminemia (albumin \< 30g/L).
* With severe heart and lung and other important organ dysfunction.
