Abstract
Background. The incidence of distant metastases of intrathoracic localization in kidney cancer, including intrathoracic lymph nodes, makes the problem of identifying and introducing knowledge about prognostic factors into clinical practice when using the surgical treatment of this disease urgent.
Aim. To identify prognostic factors in the surgical treatment of intrathoracic metastases of renal cancer.
Materials and methods. In this work, a retrospective analysis was carried out of a group of 100 patients with intrathoracic cancer metastases, almost who underwent surgical treatment in the form of removal of distant metastases. We analyzed the clinically significant factors associated with the prevalence of the tumor process in the lungs, which could affect the long-term results of treatment, as well as the influence of various instrumental research methods on the frequency of detection of intrathoracic lesions. In addition, the influence of the choice of surgical approach and the volume of surgery on the long-term survival of this group of patients was analyzed.
Results. 40 (40 %) patients had synchronous and 60 (60 %) had metachronous lung metastases. 63 (63 %) had open and 36 (36 %) – thoracoscopic surgery, 1 (1 %) patient underwent a transdiaphragmatic resection. 70 (70 %) patients had atypical lung resections. 5-year overall survival was 53.4 %, 5-year progression-free survival – 43.1 %. There was no postoperative mortality and no grade 3–4 morbidity. Following factors were associated with an overall survival during a single-factor analysis: bilateral lung lesions (р <0.0001), R0 resection (р = 0.002), Munich scale (р = 0.007). Only bilateral lung lesion were associated with an overall survival during a multifactor analysis (р = 0.001).
Conclusions. Removal of intrathoracic metastases of kidney cancer in the lung can lead to long-term survival in a significant number of patients. Achieving R0 resection is the main goal of surgical treatment.
