RESUMO
We aimed to investigate the effect of perioperative analgesia with nonselective cyclooxygenase-2 inhibitor dexketoprofen and opioid drug omnopon on the functional activity of immune cells in tumor excision murine model. Lewis lung carcinoma cells were transplanted into hind paw of C57/black mice. On the 23th day tumor was removed. Analgesic drugs were injected 30 min before and once a day for 3 days after the surgery. Biological material was obtained a day before, 1 day and 3 days after the tumor removal. IFN-γ, IL-4, IL-10 and TGF-ß mRNA levels in splenic cells were assessed by quantitative real-time RT-PCR. Cytotoxic activity of splenocytes was estimated by flow cytometry. We found that in splenocytes of mice received opioid analgesia IL-10 mRNA level was increased 2.3 times on day one after the surgery compared to preoperative level (P < 0.05), while in dexketoprofen group this parameter did not change. IFN-γ gene expression level on day 3 after tumor removal was 40% higher in splenocytes of dexketoprofen treated mice as compared with omnopon treated animals (P < 0.05). Cytotoxic activity of splenocytes on day 3 postsurgery was (62.2 ± 2.4)% in dexketoprofen against (50.2 ± 3.3)% in omnopon group. In conclusion, perioperative analgesia with cyclooxygenase inhibitor dexketoprofen in contrast to opioid analgesia with omnopon preserves higher functional activity of murine immune cells in the experimental model of tumor surgery.

AIM: To investigate the quantitative and functional status of peripheral blood lymphocytes in patients with non-small cell lung cancer during DC-vaccine therapy and identify the most informative immunological parameters which are associated with clinical outcome. MATERIALS AND METHODS: The study was conducted within the framework of randomized phase III clinical trial of DC-vaccine efficacy in patients with non-small cell lung cancer. Quantitative composition of peripheral blood lymphocytes was determined by flow cytometry. Cytokines mRNA expression level was estimated using real-time RT-PCR. RESULTS: In our study the most pronounced changes in the immune system have been defined after fourth DC-vaccine injection. Immunologic features such as reduction the MIP-1α mRNA expression level, increasing the RANTES mRNA expression level and NK-cells count, retention CD4/CD8 ratio at physiological level were associated with favorable clinical outcome after DC-immunotherapy. CONCLUSIONS: Immunological markers established in our investigation can be used for estimation of DC-immunotherapy efficiency. The results of our research are very promising, but these data should be confirmed in further studies with a large cohort of patients.
