SURGICAL TREATMENT OF PATIENTS WITH ACTH-PRODUCING NEUROENDOCRINE TUMOR OF BRONCHOPULMONARY LOCALIZATION: THE EXPERIENCE OF NATIONAL MEDICAL RESEARCH CENTER FOR SURGERY NAMED AFTER A.V. VISHNEVSKY

Objective. To create a methodological scheme for effective surgical treatment of patients with bronchopulmonary ACTH-producing neuroendocrine tumors (NET), varying severity of hypercortisolism, with minimal risk of early postoperative complications.
Methods. The study included patients who underwent examination and surgical treatment of ACTH-producing NET of bronchopulmonary localization in the period from 2004 to August 2023. Demographic information about patients, anamnesis data, results of hormonal and instrumental studies at pre- and postoperative stages, long-term treatment results have been analyzed. The control follow-up period after surgery ranged from 6 months to 5 years.
Results. The study included 74 patients. The age at the time of diagnosis of the disease ranged from 21 to 76 years, in an almost equal ratio of men and women. Due to the severity of the condition, 3 patients were denied surgical treatment. 71 patients underwent surgery. Atypical lung resection was performed (n=27 (38%)), segmentectomy (n=19 (26.8%)), lobectomy (n=25 (35.2%)) with a radicality index of R0. Typical carcinoid was verified in 48 patients (67.6%), atypical carcinoid – in 23 (23.4%). Single metastases in remote mediastinal lymph nodes were detected in 8 patients. A decrease in blood cortisol 60 minutes after the removal of the tumor was noted in 90% of patients. No postoperative complication was reported. Repeated surgical intervention for 6 patients was performed after 12-36 months of follow-up. 60 months of follow-up later it was possible to obtain data from 46 patients. The lethality was 5 patients.
Conclusion. In the surgical treatment of patients with ACTH-producing pulmonary NET it is necessary to be guided by the scale of condition severity assessment, the data of radiation diagnostics, preoperative possible verification to select an adequate volume of surgical intervention. The analysis of this experience of surgical treatment does not differ from the indicators in other world clinics. Its advantage include the absence of postoperative complications.
