Autologous lymphokine-activated killer (LAK) cells and recombinant human interleukin-2 (rIL-2) were administered intraperitoneally (IP) to 24 patients with malignancies limited to the peritoneal space. Ten patients had ovarian cancer, 12 had colorectal cancer, and one patient each had endometrial carcinoma and primary small-bowel adenocarcinoma. All ovarian cancer patients, three of twelve colorectal cancer patients, and one patient with endometrial carcinoma had received prior therapy. Patients received IL-2 100,000 U/kg every 8 hours intravenously (IV) for 3 days, and 2 days later underwent daily leukapheresis for 5 days. LAK cells were generated in vitro by incubating the peripheral blood mononuclear cells in IL-2 for 7 days and were then administered IP daily for 5 days through a Tenckhoff catheter (Davol, Inc, Cranston, RI) together with IL-2 25,000 U/kg IP every 8 hours. All but one patient completed at least one cycle of therapy. Toxic side effects included minor to moderate hypotension, fever, chills, rash, nausea, vomiting, abdominal pain and distension, diarrhea, oliguria, fluid retention, thrombocytopenia, and minor elevations of liver function tests; all of these rapidly improved after discontinuation of IL-2. One patient had a grand mal seizure, and one suffered a colonic perforation; these were felt to be treatment-related. IP fibrosis developed in 14 patients and limited repeated cyclic administration of this therapy in five patients. Two of 10 (20%) ovarian cancer patients and five of 12 (42%) colorectal cancer patients had laparoscopy- or laparotomy-documented partial responses. We conclude that LAK cells and rIL-2 can be administered IP to cancer patients, resulting in moderate to severe short-term toxicity and modest therapeutic efficacy. Further investigation of this form of adoptive immunotherapy modified to address the problem of IP fibrosis and with lower IP IL-2 doses is justified by these initial results.

Introduction: There is growing evidence describing the relation between psychological factors and the progression of colorectal cancer. Several mechanisms have been proposed but the one showing more promising evidence relies on the modulation of the antitumoral immune response by psychological factors, particularly through natural killer cells. We aimed to study the relation between natural killer cell count and anxiety, depression and anger state, trait and expression in 54 pre-surgical colorectal cancer patients.Material and Methods: We measured peripheral blood natural killer cell count and applied the State-Trait Anger Expression Inventory and the Hospital Anxiety and Depression Scale to 54 pre-surgical colorectal cancer patients. We used the Mann-Whitney U test and the Kruskal-Wallis test when appropriate to compare independent groups.Results: Patients with higher Anger Expression-Out had lower natural killer cell numbers than patients with lower Anger Expression-Out (p value = 0.008). No relation was found between natural killer cell levels and Anger State, Anger Trait, or Anger Expression-In. No difference in natural killer cell count was found between patients with and without clinical anxiety or depression.Discussion: These results suggest that, in colorectal cancer patients, natural killer cell counts are influenced by Anger Expression-Out, but not by clinical anxiety or depression.Conclusion: The unregulated emotional expression might be a conditioning factor of innate immunity. Additional studies are needed to further investigate this relation and to ascertain the clinical impact of therapeutic interventions regarding emotional regulation on the anti-tumoral immune response.

525 Background: Many kinds of genetic and environment factors are involved in colorectal cancer development. Natural killer cells (NK cells) play important roles to protect from viral infections and the early development of cancers, and it is activated or inhibited by killer cell immunoglobulin-like receptors (KIR) which bind to HLA class I. KIR genes are encoded on chromosome 19q13.4. And there are 7 kinds of activating KIRs, and another 7 kinds of inhibiting KIRs. The genetic polymorphisms of KIR genes effect the expression of KIR on NK cells, and there are ethnic differences. In this study, we were trying to investigate the KIR genotype of Korean colorectal cancer patients. Methods: DNAs were extracted from the peripheral bloods from normal populations and Korean colorectal cancer patients. KIR genes were amplified using PCR-SSP methods, and HLA-Cw genes were characterized using PCR methods. The results were analyzed between cancer patients and normal control group. Results: KIR2DL2 and KIR2DS2 were found at low rate and KIR2DL3 were found at high rate compare to the Eastern studies, but the rates were similar with Japan study. In this study, KIR2DS5 (33.2% vs. 20.8%, p-value<0.007) was increased in colorectal cancer group, and in rectal cancer subgroup, KIR3DL1 (93.2%, vs. 98.1%, p-value<0.05), KIR2DS2 (7.8% vs. 19.5%, p-value<0.01), KIR2DS4 (93.2% vs. 98.1%, p-value<0.05) were decreased significantly. HLA-Cw6 (9.1% vs. 15.7%, p-value<0.05) and HLA-Cw7 (17.4% vs. 27.7%, p-value<0.02) were decreased in colorectal cancer group, but no difference was found when they were classified to HLA-C1 and HLA-C2 group. Among the patients with HLA-C1 homozygote, KIR2DS2 was decreased significantly (5.8% vs. 14.5%, p-value<0.004). Conclusions: There are ethnic differences of KIR genotypes. KIR2DS5 is increased in Korean colorectal cancer patients, and in rectal cancer subgroup, KIR3DL1, KIR2DS2 and KIR2DS4 are decreased, so there are immunologic differences between colon and rectal cancers. And among the patients with HLA-C1 homozygote, KIR2DS2 is decreased. Therefore KIR2DS2 in presence of their ligand (HLA-C1 group) may have protective effect against colorectal cancer.
