The results of the effective use of magnetic laser therapy in the treatment and rehabilitation of cancer patients were presented. The effect of magnetic-laser therapy in the treatment of radiation-induced reactions in the patients with head and neck cancer and in the patients with breast cancer was analyzed. High efficiency of lymphedema and lymphorrhea treatment in the postoperative period in the patients with breast cancer was proved. The results of rehabilitation of the patients with gastric cancer after surgical treatment were presented. These data indicate a high effectiveness of different physical methods of treatment and rehabilitation of cancer patients

Both Epstein-Barr virus (EBV) and H. pylori (НР) have been implicated in the carcinogenesis of the stomach. The results of studying НР-infection, antiviral humoral immune response to EBV and viral load in tumor tissues as well as their prognostic significance were analyzed in 54 patients with stage I-IV gastric cancer. It was shown that high titers of IgG to viral capsid antigen (VCA) (>1: 320), IgА to VCA (>1: 10) and IgG to EBV early antigens (EA) were typical for gastric cancer patients, thus indicating high antiviral immune responses. High titers of antiviral antibodies (IgG to VCA, IgG to EBV EA) and high intensity of viral load in the tumor (more than 3 copies of EBV DNA per 105 cells) were found to correlate with absence of HP infection. On the contrary, low concentrations of serum IgG to VCA were observed in most HP-positive patients (81%). The analysis of prognostic significance of parameters associated with infectious agents showed that the only concentration of IgA to EBV VCA in blood serum had a prognostic potential in the assessment of overall survival. The 2-and 3-year overall survival rates were higher in gastric cancer patients in whom serum EBV VCA-IgA antibody titers were not detected than in patients with serum EBV VCA-IgA antibody titers of >1: 10 (43.2±1.7% and 37.7±1.9% versus 12.1±1.5% and 8.7±0.9%, respectively; р<0.05).
