[Recurrence of ovarian cancer in extraperitoneal localization after 29th years of radical surgery].

The study presents a case of ovarian cancer recurrence in extraperitoneal localization observed after twenty nine years of radical surgery and radiotherapy. New focus of ovarian cancer has been placed near right oval ligament of uterus. Long-term survival and ovarian cancer recurrence in extra-abdominal place may be taken as a confirmation an opinion about a role of multifocal neoplasia of mesothelium in pathogenesis and recurrence of ovarian cancer.

[Radiofrequency ablation in primary and metastatic hepatic tumors].

A number of alternative therapies have been used for the treatment of malignant hepatic tumors. Radiofrequency ablation (RFA) is an evolving technology being used to treat patients with unresectable primary and metastatic hepatic cancers. RFA produces coagulative necrosis of the tumor through local tissue heating.

[Techniques of thermal ablation in primary hepatic carcinoma and metastatic tumors of colorectal cancer].

Liver metastases develop in 30-50 per cent of patients with colorectal cancer. Without treatment, the median survival is approximately 7 months. Recent results from multiple investigations indicate that several minimally invasive treatment techniques are very effective for treating primary and secondary malignant hepatic tumors and they may replace surgical resection in the near future.

[Chemoembolization and ethanol ablation of primary hepatic carcinoma and metastatic tumors].

Hepatocellular carcinoma (HCC) and metastases from colorectal carcinoma are two most common malignant tumors affecting liver. Of all patients presenting with a malignant hepatic tumor, few are surgical candidates. Contraindications to hepatic resection include too many tumors, tumors in unresectable locations, insufficient hepatic reserve to tolerate resection, and other medical conditions that make the patient a poor surgical risk.
