[Immediate results of surgical treatment of advanced age patients with non-small cell lung cancer]. / Neposredstvennye rezul'taty khirurgicheskogo lecheniya nemelkokletochnogo raka legkikh u bol'nykh pozhilogo i starcheskogo vozrasta.

OBJECTIVE: To study the immediate results of surgical treatment of advanced age patients with non-small cell lung cancer (NSCLC). MATERIAL AND METHODS: We included 190 elderly and senile patients with NSCLC who underwent surgery at the thoracic department of the Tomsk Regional Clinical Hospital in 2010-2018. There were 149 men and 41 women. Cancer stage I was observed in 67 (35%) cases, stage II - 49 (26%) patients, stage III - 69 (37%) patients, stage IV - 5 (2%) patients. Squamous cell cancer was diagnosed in 94 patients, adenocarcinoma - 78 patients, large cell lung cancer - 18 patients. Paraneoplastic inflammatory complications occurred in 26% of patients, concomitant diseases - in 99% of patients. The research included anatomic lung resection with systematic mediastinal lymph node dissection and the absence of tumor at the resection line. There were 118 lobectomies and 47 pneumonectomies. In 74 cases, combined procedures were carried out. Lobectomy with pulmonary artery resection was performed in 18 patients, lobectomy with bronchial resection - in 10 cases. Twenty-five patients underwent video-assisted lobectomy. CONCLUSION: An acceptable morbidity and mortality allow you to expand the indications for radical surgery in geriatric patients with NSCLC. However, we must establish strict indications for pneumonectomy. Bronchial and angioplastic lobectomy may be an alternative to pneumonectomy in NSCLC patients.

[Circular resection of the thoracic trachea for MALT lymphoma in an 81-year-old patient]. / Tsirkulyarnaya rezektsiya grudnogo otdela trakhei pri MALT-limfome u patsientki v vozraste 81 goda.

A rare clinical observation of primary tracheal MALT lymphoma is reported and difficulties of differential diagnosis are discussed. Tracheal neoplasms are rare tumors and characterized by delayed diagnosis after clinical manifestation (tracheal stenosis and associated complications). These tumors often occur an advanced age patients that complicates examination and surgical treatment. High risk is determined by type of surgery, possible postoperative complications and senile age.

[Biphasic (dedifferentiated) osteosarcoma of the lung in the light of current ideas on biphasic tumors]. / Bifaznaia ('dedifferentsirovannaia') osteosarkoma legkogo v svete sovremennykh predstavlenii o bifaznykh opukholiakh.

The paper presents a case of biphasic (dedifferentiated) osteosarcoma arising primarily on the lung, which has not previously encountered in the literature. It provides a detailed description of its clinical, instrumental, and morphological pattern. It also analyzes the literature on the study of primary pulmonary osteosarcoma and extraskeletal osteosarcoma with high-grade transformation. This clinical case is a clear example of classic biphasic sarcoma interpreted in the context of the phenomenon of biphasic tumors. Their most important aspects (terminology, morphology, biological behavior, and a mechanism of dedifferentiation) are highlighted; the key characteristics of biphasic sarcomas are listed.
