Study Details

Study Description

Brief Summary

Peritoneal disease at initial presentation for patients with gastric adenocarcinoma (GA) is frequent, with 15-31% of patients presenting with peritoneal metastases (PM) at surgical exploration. The prognosis of patients with PM is poor, overall survival (OS) ranging from 8 to 13 months, reinforcing the importance of optimal patient selection before surgical management of GA.

Indocyanine Green (ICG) fluorescence imaging for intraoperative detection of PM has been described in recent literature as a useful tool in patients undergoing cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancies to increase the detection of PM during surgery. However, the role of ICG for patients with GA, and its role during diagnosic laparoscopy (DL), remain unknown.

Condition or Disease Intervention/Treatment Phase
  • Drug: Indocyanine green
Phase 2

Detailed Description

This is a multicentric, prospective study . Patients will be referred to one of seven surgeons specialized in the surgical management of gastric cancer. Patients will undergo DL, with intravenous (IV) injection of 0.25 mg/kg of free ICG at the start of the surgery. DL will be first performed without fluorescence imaging in the standard fashion, with identification of potential PM. A first peritoneal cancer index (PCI) score will be calculated. Fluorescence imaging will then be performed, and correlation with previously identified lesions will be assessed and a second PCI score (with ICG) will be calculated. Biopsies will be performed to confirm the metastatic status of the lesions. Any suspicion for additional lesions visualized only under fluorescence imaging will be biopsied as well. Peritoneal fluid cytology will be performed at the beginning of the surgery.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Gastric cancer with ICG

Patient to receive IV ICG during diagnostic laparoscopy.

Drug: Indocyanine green
0,25mg/kg IV at the start of the surgery,
Other Names:
  • ICG
  • Outcome Measures

    Primary Outcome Measures

    1. Number of patients with additional lesions detected with ICG. [18 months]

      Patients with peritoneal metastases, in whom additional lesions are detected with ICG.
