[The degree of tumor vascularization as a prognostic factor of the efficacy of neoadjuvant polychemotherapy in breast cancer].

A procedure for obtaining microcirculation coefficient is described. It is based on the phenomenon of formation of a focus of radionuclide hyperfixation on scintigrams of tumor area due to embolization of its arterioles and precapillaries with radionuclide. The method was used in 26 breast cancer patients before neoadjuvant chemotherapy. A direct correlation between the microcirculation coefficient and degree of tumor-induced pathomorphosis of tumor cells was established. The coefficient values proved more or less predictive of tumor response to chemotherapy.

[Study of the renal venous outflow using digital subtraction angiography].

A venous phase of digit subtraction angiography (DSA) of the kidneys was evaluated in 87 urologic patients. The subtraction allows satisfactory visualization of the renal veins. Amplification of the image and its early emergence indirectly suggest pathological arteriovenous shunt confirmed by intraoperative rheography. Investigation of the renal veins and venous outflow from the kidneys with DSA bears sufficient information and is less traumatic versus standard retrograde venography.

[Combined digital subtraction angiography and cholangiography in assessing the spread of the tumor process in pancreatobiliary cancer].

The paper is concerned with comparative assessment of the efficacy of digital subtraction angiography and routine angiography in assessing tumor spreading in pancreatobiliary cancer. A combined method of digital subtraction angiography and cholangiography was developed and performed in 41 patients with pancreatobiliary cancer permitting maximum information on the topical location and spreading of a tumor process. The clinical importance of the obtained results permitted recommending simultaneous digital subtraction angiography and cholangiography in patients with hepatobiliary cancer.

[Phlebography of the mediastinum in lung cancer].

The state of the major mediastinal veins was studied in 113 patients with central cancer of the right lung upper lobe with metastases to the regional lymph nodes. Routine angiography was performed in 92 patients, digital subtraction angiography--in 21 patients. Vascularization was shown to be more common in and adenocarcinoma. The authors identified 2 groups of angiographic signs: marked and doubtful ones. They have been of opinion that only the presence of marked signs can be a contraindication for surgical intervention. The informative value of routine angiography was compared with that of digital subtraction angiography.
