[Current possibilities of detecting and diagnosing the early forms of lung cancer].

A long-term experience with oncopulmonary examinations points to their efficacy in detecting lung cancer, early forms included. As a result, the number of primary patients operated on for lung cancer or undergoing lung resection has grown in Leningrad for the past 17 years from 15.6 to 22% and from 13.2 to 19%, respectively. The best diagnostic results for central cancer have been obtained in application of bronchoscopy and with transcutaneous needle biopsy--for peripheral cancer. (The rate of morphological verification of cancer was over 96% for either procedure). The following patterns of early forms of central cancer of the lung have been identified: Ca in situ, microinvasive cancer, incipient invasive cancer and advanced invasive cancer.

[Bronchoscopic diagnosis of peripheral lung cancer].

The diagnostic value of bronchologic procedures in identification of peripheral cancer of the lung versus tumor's size, endoscopic pattern of bronchial lesion and tumor position with respect to the root of the lung was assessed. Rigid endoscopes and bronchofibroscopes were used in 806 patients with peripheral lung cancer. Bronchoscopic diagnosis of cancer was morphologically confirmed in 64.9% (respiratory endoscope alone--51.3 +/- 3%; bronchofibroscope or combined use of both devices--71.9 +/- +/- 2%).

[Puncture of a bronchial tumor in the bronchoscopic diagnosis of lung cancer].

An analysis of the results of bronchial tumor biopsy performed in 200 lung cancer patients is reported. Morphological verification proved feasible in 193 of 200 patients. Biopsy and puncturing of the tumor are found to be most advantageous technics for the material take during bronchoscopy. Contrary to biopsy, an efficiency of transbronchial puncturing is not affected by the character of tumor growth and its morphological structure. A combined use of biopsy and puncture makes it possible to increase the percentage of morphologically supported diagnosis of pulmonary cancer. Transbronchial puncturing is also an efficient maneuver for detection of cancer recurrence in the bronchial stump and a residual tumor after conservative therapy. Endoscopic signs of the peribronchial pattern of tumor growth are absolute indications to its puncture.

[Endoscopic diagnosis of postoperative stomach cancer].

The authors examined endoscopically the esophagus and stomach in 309 patients, previously operated upon for gastric cancer (258), ulcer of the stomach or duodenum (36) and benign gastric tumors (15). They estimated the value of this method for establishing diagnosis of the operated stomach cancer and also the importance of histological and cytological methods in the complex diagnosis of this pathology. Moreover, roentgeno-endoscopic correlations were made. Cancer of the operated stomach was detected in 59 patients, it was suspected in 8, other lesions were found in 194. no changes in the operated stomach were found in 48. It is stated that endoscopy is more advantageous than roentgenological examination in establishing the diagnosis of tumor pathology of the operated stomach. Histological and cytological findings are of considerable value in making the correct diagnosis. These methods are mostly informative in an exophytic form of the tumor growth.

[Results of treatment of postoperative bronchopleural complications in lung cancer].

An analysis of the results of treatment in 138 patients with bronchopleural complications after 1400 operations on the lung for cancer is given. Conservative methods of therapy (punctures and drainage of the pleural cavity, instillation and of the fisula with 30% silver nitrite and intratracheal injections of antibiotics) were utilized in 105 patients with bronchial fistulas and pleural empyemas. Thirty there patients were treated surgically (tamponade, thoracoplasty, rethoracotomy with suturing of the bronchial fistula, transsternal suturing of the bronchial fistulas). The rate of mortality from bronchopleural complications was 4.8%, i.e. one third of all causes of death. However, recently it reduced more than twice in comparison with the initial period. The direct causes of lethal issues are complications on the part of other organs: pneumonia of the remained lung (24), septicopyemia (12), hemorrhage (10), and others (19).
