Standard immunological parameters measuring non-specific cellular immune reactivity were determined in 175 patients with different stages of gastric cancer prior to surgery and during follow-up. Several tests measuring monocyte activity were also employed. The total number of T cells and their subpopulations Ta and T29o was unchanged except depression of T29o in stage IV. The blastogenic response of lymphocytes to PHA as assessed by stimulation of protein synthesis was only depressed in stage IV. In contrast the PHA-induced lymphokine production was increased in all patients but the differences were significant for stage III and IV. Monocyte Fc receptor expression was increased in stages II-IV, while nitro blue tetrazolium reduction and antibody dependent cellular cytotoxicity of monocytes was elevated in stage IV. The number of extractable monocytes was not increased. Longitudinal studies suggested that most of the parameters normalized during follow-up. No major long-term impact of chemoimmunotherapy (5-FU + BCG) on the immune parameters was observed except a transient increase in PPD reactivity approximately 1 year after commencement of treatment. In patients with stage III gastric cancer the increased occurrence of suppressor cells (mostly monocytes) and elevated cytostatic activity of monocytes was associated with a longer survival while the increased lymphokine production and Fc receptor expression were seen in the group of patients succumbing earlier. We concluded that most of the changes in immune parameters were seen only in advanced disease and paradoxically disappeared in the course of disease. The determination of monocyte activity seems to be a sensitive indicator of immune system dearrangements in earlier stages of cancer and a useful prognostic factor in gastric cancer.

In this paper, we present evidence that the red ginseng powder from Panax ginseng C.A. Meyer inhibits the recurrence of AJCC stage III gastric cancer and shows immunomodulatory activities during postoperative chemotherapy, after a curative resection with D2 lymph node dissection. Flow cytometric analyses for peripheral T-lymphocyte subsets showed that the red ginseng powder restored CD4 levels to the initial preoperative values during postoperative chemotherapy. Depression of CD3 during postoperative chemotherapy was also inhibited by the red ginseng powder ingestion. This study demonstrated a five-year disease free survival and overall survival rate that was significantly higher in patients taking the red ginseng powder during postoperative chemotherapy versus control (68.2% versus 33.3%, 76.4% versus 38.5%, respectively, p < 0.05). In spite of the limitation of a small number of patients (n = 42), these findings suggest that red ginseng powder may help to improve postoperative survival in these patients. Additionally, red ginseng powder may have some immunomodulatory properties associated with CD3 and CD4 activity in patients with advanced gastric cancer during postoperative chemotherapy.
