Immune Status of Pancreatic Cancer Patients Receiving Cryosurgery.

Cryosurgery used on patients with unresectable pancreatic cancer improved their quality of life, but mainly because of the pain relief. In postoperative patients, multifaceted changes in immunity were found, and the state of the immune system prior to surgery often was a decisive factor to indicate whether further disorders in the postoperative period would develop, or by contrast, it would boost its recovery. Some patients receiving cryosurgery showed immune system imbalance and activation, and of antitumor immunity in particular.

[Robot-assisted and laparoscopic partial splenectomy for nonparasitic cysts].

21 patients with nonparasitic spleen cysts were operated. Robot-assisted (RA) interventions were applied in 10 cases, laparoscopic--in 11 patients. Men surgery duration was 124 minutes in case of RA-technique and 120 minutes if laparoscopy was used.

[Complications after radio-frequency thermoablation of liver tumors].

Results of treatment of 124 patients (228 operations) were analyzed. Complication rate was 19.2%, whereas severe complications were observed in 4.

[Regional intraarterial chemoimmunotherapy in complex treatment of patients with colon cancer complicated by metastatic lesion of the liver].

Results of combined treatment of 48 colon cancer patients with metastases to the liver are analyzed. Efficacy of regional intraarterial chemoimmunotherapy with recombinant interleukine-2 (ronkoleukine) is evaluated. The results of the treatment demonstrate that regional intraarterial chemoimmunotherapy with recombinant interleukine-2 is a safe and promising method in combined treatment of advanced colon cancer, increases survival and improves quality of life.

[Radio-frequency ablation appliance in resection of the liver].

Pilot experience with "Radionics Cool-Tip RF System" appliance for radio-frequency ablation (RFA) in hepatic resection in the patients with focal lesions of the liver is presented. Advantages of RFA as an alternative method for hemostasis are demonstrated. With this technique bisegmentectomy (II - III) was performed in 4 patients, right-sided hemihepatectomy - in 2 patients.

[Regional arterial chemoembolisation and chemoimmunoembolisation in combined treatment of colon cancer with hepatic metastases].

Results of locoregional intraarterial treatment with recombinant Interleukine-2 (Ronkoleukine) in patients with hepatic metastases of colon cancer are presented, efficacy of locoregional arterial chemoembolisation and chemoimmunoembolisation in combined treatment of hepatic metastases are evaluated. The drugs were administered through catheter installed in the right or left branch of the own hepatic artery with Selinger method. Endovascular treatment was carried out 6-10 months after removing of primary tumor.
