The Efficacy of Surgical Treatment After Neoadjuvant Chemotherapy Plus Intraperitoneal Immunotherapy Versus Chemotherapy Alone for Patients With Positive Wash Cytology Gastric Cancer

December 12, 2016 updated by: Moscow Clinical Scientific Center

Prospective Randomized Phase II Clinical Trial: the Efficacy of Surgical Treatment in Combinations With Intraperitoneal Immunotherapy and Systemic Chemotherapy in Patients With Gastric Cancer and Verified Free Cancer Cells

The purpose of this study is to determine whether intraperitoneal immunotherapy (with interleykin-2 - human cytokine reaction activator) with systemic chemotherapy will be more effective than systemic chemotherapy alone in patients with gastric cancer and verified free cancer cells in abdominal cavity in improving the long term outcomes and overall survival of further surgical treatment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: neoadjuvant chemoimmunotherapy
Patients with gastric cancer and verified free cancer cells who receive 1 course of intraperitoneal immunotherapy with interleykin-2 + 3 courses of systemic chemotherapy (Cisplatin + 5-FU). In case of downstaging (M1 -> M0) surgical treatment will be performed.
Procedure: neoadjuvant chemoimmunotherapy
No Intervention: neoadjuvant chemotherapy
Patients with gastric cancer and verified free cancer cells who receive 3 courses of systemic chemotherapy (Cisplatin + 5-FU). In case of downstaging (M1 -> M0) surgical treatment will be performed.
