In classical oncological literature two mechanisms for tissue aggression in patients with cancer have been described. The first is the progressive invasion, infiltration and destruction of tissues surrounding primary malignant tumor or their metastases; the other includes alterations produced in remote sites that are not directly affected by any focus of disease, the so called paraneoplastic phenomenon. The non-invaded tissue which surrounds a primary malignant tumor or its metastases has been usually considered a normal tissue . In this work we describe the ultrastructural changes observed in hepatocytes located next to metastases from diverse malignant tumors.Hepatic biopsies were obtained surgically in patients with different malignant tumors which metatastized in liver. Biopsies included tumor mass, the zone of macroscopic contact between the tumor and the surrounding tissue, and the tissue adjacent to the tumor but outside the macroscopic area of infiltration. The patients (n = 5), 36–75 years old, presented different tumors including rhabdomyosarcoma, leiomyosarcoma, pancreas carcinoma, biliar duct carcinoma and colon carcinoma. Tissue samples were processed with routine techniques for transmission electron microscopy and observed in a Hitachi H-500 electron microscope.

Background/Aim. Ovary is the organ of the female reproductive system most commonly affected by metastases. The aim of the study was to determine the frequency and features of metastatic ovarian tumors (MOT) depending on the site of the primary malignant tumor. Methods. The study group consisted of 488 patients with histopathologically confirmed ovarian cancers treated at the Clinic of Oncology, Clinical Center Nis, in the period from 1 January 1998 to 31 December 2005. MOT were found in 41 patients. Regarding the site of the primary malignant tumor, those with secondary ovarian tumor were divided into two groups: group A - primary malignant tumor involving the genital organs (n = 30) and group B - primary malignant tumor of extragenital origin (n = 11). Results. MOT were confirmed in 8.40% (41/488) of the patients. Secondary ovarian malignancies were the consequence of endometrial carcinoma spreading in 73.17%, breast carcinoma in 19.51%, stomach carcinoma in 4.88% and colon carcinoma in 2.44% of the cases. No significant differences were found between the group A and group B by the factors of age, body mass index, parity and menopausal status. Contrary to the group A, metastatic tumors in the group B patients were more commonly asymptomatic (p < 0.001), bilateral (p < 0.05), with larger ovarian diameter (p < 0.05), associated with ascites (p < 0.001) and abdominal metastases (p < 0.01), all of statistical significance. Conclusions. Metastatic tumors made up 8.40% of ovarian neoplasmas. With non-genital primary tumors, secondary ovarian deposits were frequently asymptomatic, bilateral, associated with larger ovarian diameter, ascites and abdominal metastatic deposits, compared to malignant tumors of genital origin.

Objective. To analyze the peculiarities of surgical treatment of a mitral stenosis, complicated by massive thrombosis of left atrium. Маterials and methods. The group analyzed, operated in the Institute, consisted of 344 patients. Thrombosis of left atrium was considered a massive, when thrombotic masses have occupied no less than one third of its volume, not mentioning an auricle of atrium. Results. Hospital lethality after change of a mitral valve have constituted 4.2% and directly depended on from a degree of the left atrium thrombosis (р < 0.05). After open mitral comissurotomy hospital lethality was not observed, witnessing the expediency of the thrombosis matrix extraction. Conclusion. During the operation for a massive thrombosis of left atrium it is important to remove a maternal base of thrombotic bed and to eliminate the left atrium auricle, what lowers essentially the risk for lethality and thromboembolic complications on a hospital stage. Doing preoperative computed tomography of head and abdominal organs constitutes obligatory condition for exclusion of a hidden thromboembolism occurrence.
