[67Ga-citrate in the differential diagnosis of benign lesions and lung cancer]. / 67Ga-tsitrat v differentsial'noi diagnostike dobrokachestvennykh obrazovanii i raka legkogo.

A total of 77 patients with tumors and benign lesions of the lungs were examined. In addition to the x-ray method the use of a study with 67Ga-citrate was found appropriate in the differential diagnosis of spheroidal lesions of the lungs.

[Parathyrin content of lung cancer patients undergoing surgical and chemotherapeutic treatment]. / Soderzhanie paratirina u bol'nykh rakom legkogo pri operativno-khimioterapevticheskom lechenii.

Parathyrin concentration was determined in lung cancer patients prior to and after operation by using a radiological method. A preoperative elevated level of parathyrin was noted in 60.4% of the patients. Radical surgery resulted in the return of the parathyrin level to normal, and toxic effects caused by chemotherapy were accompanied by its sharp increase. A similar increase in the parathyrin level attends generalization of a tumor process.

[Combined (surgical and drug) therapy of lung cancer]. / Kombinirovannoe (khirurgicheskoe i lekarstvennoe) lechenie bol'nykh rakom legkogo.

The paper deals with an evaluation of the immediate and end results as well as the rates of lung tumor progression in the course of surgical and combined therapy including different schedules of long-term administration of preparation CCNU. Combined therapy was shown to be followed by a longer remission and survival, as compared with cancer patients in control. The said effect was particularly pronounced is cases of squamous-cell carcinoma and in patients treated with levomycetin.

[Modern possibilities of the surgical treatment of lung cancer]. / Sovremennye vozmozhnosti khirurgicheskogo lecheniia raka legkogo.

The twenty-year experience gained in the surgical treatment of 1,100 cases of lung cancer at the Clinic of Thoracic Oncology and Reanimation Department of the Center is summarized. Surgical and anesthetic procedures, premedication and methods of postoperative intensive care following resection or removal of the lung are discussed. The paper contains a detailed description of age-associated and concommitant diseases. Factors contributing to extension of indications for surgical treatment of lung cancer are analysed. Prevention and treatment of postoperative complications are considered.

[Carcinoembryonic antigen in lung cancer patients]. / Rakovo-émbrional'nyi antigen u bol'nykh rakom legkogo.

Radioimmunoassay of carcino-embryonic antigen was conducted in lung cancer patients before and after surgery. Elevated concentrations of the antigen before operation was registered in 84.8% of cases. Antigen levels returned to normal after radical removal of tumor and rose sharply as a result of chemotherapy toxicity. A similar pattern of changes in carcino-embryonic antigen level was observed in cases of disseminated and recurrent cancer.

[Possibilities for the early detection of lung cancer recurrences and metastases]. / Vozmozhnosti rannego vyiavleniia retsidivov i metastazov raka legkogo.

The results of surgical treatment in 260 lung cancer patients are analysed. The purposeful dynamic examination of patients by modern technics enabled a recognition of progressive tumor growth in 112 of 137 patients (81,75%) during the first 18 months after the operation. To reveal subclinical recurrences and metastases in the chest organs roentgenological and bronchological methods, positive 67Ga-citrate scintigraphy seem to be preferable. In skeletal involvement scanning findings are mostly indicative in this respect. Scanning of the organs in operable patients as a mandatory investigation is unlikely to be rational.
