Colposcopic features of cervical oncotropic papilloma-virus infection in patients with various pathology of uterine cervix

In order to estimate the colposcopic manifestations of cervical oncotropic human papilloma-virus (HPV)-infection, a total of 693 patients were examimed. Among them, there were 298 patients with benign tumors pathology, 57 patients with 1-3 Grade cervical dysplasia of mucosa, 50 patients with uterine cervix cancer, 288 healthy women. All patients underwent bimanual examination, taking of cervical smears for cytological examination and uterine cervix colposcopy. Diagnosis for HPV16/18 infection was made by the method of polimerase chain reaction. А large variety in colposcopic manifestations of HPV-infection was found, namely: areas of atypical vessels, leukoplakia sites,fields of atypical epithelium, iodine-negative sites. It was related to the influence of oncogenic types of HPV infection. In these patients,fields of atypical epithelium, atypical vessels, iodinenegative areas were observed 1.2, 2.5, 10.5 times more frequently, respectively. It was found that all varieties of papillomas occurred among patients with pathology, whereas flat condylomas presenting the most difficulties of or diagnosis prevailed in patients with cervical neoplasms and uterine cervix cancer The most pronounced colposcopic evidences of uterine cervix epithelium malignancy were observed in patients with virus-positive uterine cervix cancer.

PHOTODYNAMIC THERAPY IN MULTIMODALITY TREATMENT OF PLISS LYMPHOSARCOMA AND UTERINE CERVIX CANCER-5

Background. Malignant tumors management using conventional treatment modalities is associated with poor outcomes. Objective of the study. To assess photodynamic activity of Photolon as monotherapy, as well as in combination with radio- and chemotherapy in an experiment.Material and methods. The research was done on HeLa monolayer culture (human uterine cervix carcinoma), 97 white random-bred rats with Pliss lymphosarcoma and 42 mice (CBA) with uterine cervix cancer-5 (UCC-5). Results. The amplification factor in Photolon photoirradiation was 65.1 in terms of the cytostatic effect and 98.5 in terms of cytotoxic effect. Photodynamic therapy enhances the efficacy of radiotherapy, since it reduced Pliss lymphosarcoma growth rate in rats down to 33.7% and UCC-5 growth rate in mice down to 14.9% of the intact control level (p<0.05). Conclusion. It is advisable to include photodynamic therapy in multimodality treatment.
