[Ultrasonically guided aspiration biopsy in the diagnosis of liver tumors].

The paper is concerned with the analysis of the results of sonographically guided biopsy of hepatic tumors which had been carried out in 30 outpatients suffering primary cancer of the liver (3 cases), metastases (16), lymphosarcoma (2), cysts (2), adenoma (2), hemangioma (4) and hydatidiform mole (1 patient). The sensitivity of the method in tumor diagnosis was 89%, specificity--80%. Ultrasonographic features of the liver pathologies were studied versus morphologic type.

[Ultrasonic tomography in the diagnosis of diseases of the thyroid gland].

The paper deals with the characteristics of application of microwave computed tomography in diagnosis of most frequent tumors of the thyroid gland in 146 surgical cases. The role and scope of microwave studies carried out in dynamic monitoring thyroid cancer patients to assure early detection of metastasis and recurrence are discussed.

[Complex preoperative diagnosis of the dissemination of stomach cancer to abdominal and retroperitoneal organs and tissues].

An analysis of 136 cases of stomach cancer led to the determination of the role and place of gamma-topography, echography, computerized x-ray tomography, angiography and laparoscopy in specified preoperative diagnosis of extra-organ spreading of primary tumors. The informative value and shortcomings of certain methods were shown. A high accuracy of the entire set of diagnostic procedures (94.

[Ultrasonic tomography in the diagnosis of pancreatic cancer].

The results of an ultrasonic tomographic study of 77 patients are presented. Cancer of the pancreas was identified in 50 patients. The diagnosis was verified by a complex examination and surgical evidence.

[Possibility of evaluating the degree of dissemination of malignant tumors of the bladder using ultrasonic tomography].

The paper discusses the results of an analysis of degree of bladder cancer expansion with the aid of ultrasonic tomography. The results of tomography were compared with surgical and pathohistologic findings. The study group included 94 patients with bladder cancer.

[Potential ultrasonic study in the early diagnosis of rectal cancer recurrence].

The paper is concerned with the results of ultrasonic tomography carried out in 487 radically-operated cases of rectal cancer. Tumor was detected in 103 out of 136 patients with clinically manifest recurrence (76.9%) (group 1).

[Evaluation of the effectiveness of preoperative polychemotherapy of nephroblastomas in children by angiography, ultrasonic tomography and computed tomography].

The results of preoperative polychemotherapy of nephroblastoma in 14 children are presented. Ultrasonic tomography, computed tomography and angiography were performed in all the patients before and after medication. The findings on the efficacy of polychemotherapy were assessed on the basis of surgical evidence and, in particular, resected material examination.

[Ultrasound tomography in the topical diagnosis and evaluation of results in the treatment of patients with stage III and IV ovarian cancer].

The paper describes an experience with ultrasonic tomography of the abdominal cavity and small pelvis in 34 cases of stage III and IV ovarian cancer who received polychemotherapy. In application of the said procedure, the topography and size of primary and disseminated tumors were ascertained and the immediate effect of medication assessed. The results of ultrasonic tomography were analysed in combination with other methods of research.

[Morphofunctional characteristics of the gastric mucosa in subacute local irradiation of the lumbar-aortic region in lymphogranulomatosis].

A decrease in acid secretion by gastric mucosa was registered 10-14 days after irradiation of the lumbal area in six patients with lymphogranulomatosis who were examined before irradiation, 10-14 days and 3-3.5 months after irradiation. Acid production indices came back to normal 3-3.

[Importance of thermography in the overall examination of oncological patients].

Possibilities of remote thermography for differential diganosis of malignant and bening tumours are described. It helps in more exact definition of tumours topography and distribution for better planning of their irradiation. Diagnostic accuracy at the combined thermographic and radioisotope investigations was proved on 153 women with mammary gland diseases and on 77 women with soft tissue damage.
