Background and Objectives: Immune status in the peritoneal cavity of patients with gastric cancer remains largely unknown. To clarify the clinical significance of the host immune response within the peritoneal cavity, we examined the levels of interferon‐gamma (IFN‐γ), a type 1 cytokine, and interleukin‐10 (IL‐10), a type 2 cytokine, in peritoneal washings obtained from patients with gastric cancer. Methods: Both the concentrations of IFN‐γ and of IL‐10 in peritoneal washings obtained during surgery from 56 patients with gastric cancer were determined by an enzyme‐linked immunosorbent assay. Results: The IFN‐γ level was not correlated with the IL‐10 level. The IL‐10 level increased in a stage‐dependent manner. The high IL‐10 level correlated with an unfavorable outcome, whereas there was no relationship between the IFN‐γ level and survival rate. However, among the stage III–IV cancer patients, the high IFN‐γ level correlated with a favorable outcome, while there was no relationship between the IL‐10 level and survival rate. Conclusion: Although the IL‐10 level increases with tumor progression, the outcome of patients with advanced gastric cancer may be affected by the IFN‐γ level, but not by the IL‐10 level, in the peritoneal cavity.
