[Cytologic differential diagnosis of various peripheral lung cancers]. / Tsitologicheskaia differentsial'naia diagnostika razlichnykh variantov perifericheskikh opukholei lëgkikh.

The data on 25 cases of histologically verified bronchioloalveolar carcinoma and papillary adenocarcinoma are discussed. Reliable differential diagnostic cytological features of both diseases were established using a statistical, program and fine-needle biopsy findings. Statistical analysis data pointed to the sets of cytological features: "serial pattern--clear cell boundaries" and "serial pattern--presence of macrovacuoles" as a major factor of accuracy of bronchiolo-alveolar carcinoma and papillary adenocarcinoma diagnosis. These cytological features may be used for reliable diagnosis of the diseases.

[Cytological differential diagnosis of different variants of peripheral lung tumors]. / Tsitologicheskaia differentsial'naia diagnostika razlichnykh variantov perifericheskikh opukholei legkikh.

Cytological differential diagnostic features of bronchiolo-alveolar carcinoma and papillary adenocarcinoma are established basing on the material of needle biopsies by means of Statistica program. It is found that the strongest influence on the cytological diagnosis of these two tumors is associated with the following pairs of cytological features: lane--clear-cut cell borders and lane--the presence of macrovacuoles.

[Feasibility of pre-operative cytologic diagnosis of pathologic processes in the breast]. / Vozmozhnosti dooperatsionnoi tsitologicheskoi diagnostiki patologicheskikh protsessov molochnoi zhelezy.

Results are available of clinical and cytological diagnosis for 200 patients with histologically established benign lesions of the mammary gland. The use of cytological method at the presurgery stage decreases the number of unjustified carcinoma suspects up to 5%. True cytological diagnosis is established in 90% of mastopathies, 84.6% of fibroadenomas and 80.8% of the inflammation cases. Pseudopositive conclusions about carcinoma were made in 2 cases (1% of all the examinees). Thus, the precision of the presurgical cytological diagnosis of benign breast lesions is 94%. This allows to consider it as a highly efficient method of presurgical morphological diagnosis.

[Urgent morphologic diagnosis of tracheal tumors in the course of roentgeno-endoscopic study]. / Srochnaia morfologicheskaia diagnostika opukholei trakhei v protsesse rentgenoéndoskopicheskogo issledovaniia.

84 tracheal tumors the correct diagnosis of which was established during roentgenoendoscopical investigation combined with urgent cytological diagnosis are reported. Cytological fast diagnosis can be considered a reliable method of morphological diagnostics.

[Carcinoid tumors of the lung]. / Kartsinoidnye opukholi legkikh.

Detailed cytological, histological and electron microscopic characteristics of pulmonary carcinoid tumors are listed on the basis of surgical clinic material. Various variants of the carcinoid tumors structure, their differential diagnosis are presented.

[Possibilities of various diagnostic methods in the assessment of the state of axillary lymph nodes in breast cancer]. / Vozmozhnosti razlichnykh diagnosticheskikh metodov issledovaniia v otsenke sostoianiia podmyshechnykh limfaticheskikh uzlov pri rake molochnoi zhelezy.

The incidence of axillary lymph nodal metastases in breast cancer is proportional to the size of a focus: To is 25 +/- 25%, T1-33 +/- 17%, T2-55 +/- 7%, T3-65 +/- 11%, the choice of the optimum treatment regimen requires more accurate preoperative detection of metastatic lymph nodes. Ultrasound technique (its accuracy is 80%, sensitivity-88%) is of the most diagnostic value in the detection of metastatic lymph nodes. The absence of echographic signs supports the nonspecific nature of changes. Palpation is preferable in nonspecific axillary lymph nodal lesions. The status of axillary lymph nodes in breast cancer may be correctly assessed by comprehensive clinical and ultrasonic studies of the axillary area wherein, supplementing each other, each technique yield the maximum information.

[The differential diagnosis of peripheral lung formations (cytological research)]. / Differentsial'naia diagnostika perifericheskikh obrazovanii legkikh (tsitologicheskoe issledovanie).

The following pulmonary lesions were studied: carcinoma, carcinoid, tuberculoma, chondromatous hamartoma, chronic non-specific inflammatory process. Material was obtained through fiber bronchoscopy and roentgeno-endoscopical examination. Pappenheim staining in the modification of Astrakhantsev-Nechaeva and Ziehl-Neelsen staining were used. 80 cases within 1993 were studied, among them 71 peripheral lung carcinomas. 3 carcinoids, 3 tuberculoses, 1 non-specific inflammation. Basic cytological criteria are summarized which will improve the quality of the presurgical diagnosis.

[Cytomorphologic monitoring in the complex treatment of patients with cancer of the endometrium]. / Tsitomorfologicheskii monitoring v kompleksnom lechenii bol'nykh rakom éndometriia.

The paper is devoted to analysis of clinicomorphological data on the status of a primary endometrial tumor in 209 endometrial cancer patients, treated by radical and palliative radiation therapy (112 patients) and the combined method (88 patients) including preoperative intensive concentrated intracavitary irradiation and hormonotherapy. Dynamic cytological monitoring was performed during radiation therapy and in a period up to 12 mos. after the discontinuation of antitumor therapy. Clinicoinstrumental investigations are of low informative value to make conclusions of the time course of tumor regression and its rates, and of the outcome of disease. Dynamic cytomorphological monitoring is an important stage in the integrated diagnosis of endometrial cancer, especially in patients who cannot be operated upon as a result of tumor spreading or somatic contraindications.
