[Regional chemotherapy in treatment of patients with unresectable liver metastases of uveal melanoma].

Purpose: Retrospective efficacy analysis of transcatheter arterial treatment for unresectable liver metastases of uveal melanoma.

Materials And Methods: There were performed 38 courses: hepatic arterial chemoembolization with Lipiodol (HACE, n 9) and combination of HACE with hepatic artery infusion (HAI, n = 29). In 9 patients we used the following chemotherapeutic agents: doxorubicin (10-50mg), carboplatin (150 to 450 mg), dacarbazine (200-400mg), mustophoran (360-624mg) and mitomycinum C (5-10mg).

ARTERIAL CHEMOINFUSION IN PATIENTS WITH LOCALLY ADVANCED AND METASTATIC PANCREAS CANCER.

The chemoinfusions (310) were carried out in celiac trunk in 167 patients with non-removed pancreas cancer at the period from 2000 to 2015. Locally advanced timorous process (stage III, n=79) was revealed in 79 patients and liver metastases (stage IV, n=88) were noted in 88 cases. The celiac axis infusion by Gemcitabine (1000 mg/m²) was applied for patients and GEMOX (Gemcitabine+Oxaliplatin 75 mg/m²) has been using since 2012.

CLEANING OF METAL SURFACES FROM MICROORGANISMS-BIODESTRUCTORS BY COMBINED USE OF ULTRASOUND GENERATOR <> AND AIR DECONTAMINATION UNIT <>.

The effort was made to assess the feasibility to remove microorganisms from surface of materials with the help of high-intensity ultrasound generator <> and further air decontamination using unit <>. The test data guided construction of a system capable to eliminate completely a mature association of microorganisms from aluminum surfaces. The combined use of 2 units resulted in total decontamination of atmosphere.

[Long-term results of combined x-ray endovascular surgical treatment of patients with ductal adenocarcinoma of the pancreatic head].

On the basis of the results of treatment of 105 patients with locally advanced ductal adenocarcinoma of the pancreatic head the authors present the results of work over a period of time since 1999 to 2009. In the main group the combined treatment was used for 51 patients: the non-adjuvant selective chemoembolization of the pancreatic head adenocarcinoma was performed, than standard gastropancreatoduodenal resection with lymphodesection and 6 cycles of adjuvant chemoinfusion in celiac trunk were completed. In control group standard gastropancreatoduodenal resection was performed.
