[Treatment of malignant effusion]. / Sravnitel'naya kharakteristika metodov lecheniya metastaticheskogo plevrita (obzor literatury).

Malignant effusion complicates more than 15% of all cancers in delayed stages of progression. The most common causes of metastatic pleuritis are lung cancer, breast cancer, ovarian cancer, lymphoproliferative diseases or dissemination of gastrointestinal tumors. Malignant effusion is associated with negative prognosis for overall survival regardless of etiology of tumor, significantly complicates the course of the underlying disease, impairs life quality and complicates treatment. Despite various methods for pleural cavity obliteration in recurrent metastatic pleuritis, there is still no a uniform approach to choosing the optimal treatment strategy. We analyzed the main methods of conservative and surgical treatment of recurrent metastatic pleuritic regarding efficacy, risk of recurrence and reproducibility.

[Clinical efficacy of ct-guided transthoracic needle biopsy of peripheral lung lesions]. / Klinicheskaya effektivnost' transtorakal'noi biopsii perifericheskikh novoobrazovanii legkikh pod kontrolem MSKT.

OBJECTIVE: To evaluate the effectiveness of a step-by-step protocol for GT-guided transthoracic biopsy in verification of peripheral lung tumors. MATERIAL AND METHODS: A retrospective analysis of the results of GT-guided transthoracic biopsies of focal lung neoplasms was performed between October 2019 and December 2020. The analysis included the results of 176 biopsies in 158 patients. RESULTS: Primary biopsy was informative in 139 (87.97%) out of 158 patients. There were 155 (88.07%) informative and 21 (11.93%) non-informative biopsies. Lung adenocarcinoma was diagnosed in 41 (25.95%) patients, squamous cell carcinoma in 35 (22.15%) patients, and small cell carcinoma in 9 (5.7%) patients. There were 17 (10.76%) patients with uninformative biopsy results. Sensitivity, specificity and accuracy were 86%, 95.5%, and 87.8%, respectively. PPV was 98.9%, NPV - 58.3%. Various complications occurred after 65 (36.93%) out of 176 biopsies (95% CI 30.15-44.27). Pneumothorax followed by pleural drainage was detected after 8 (4.55%) biopsies. CONCLUSION: Accuracy of a step-by-step protocol for transthoracic biopsy was 88% that is not inferior to similar results in large-scale studies devoted to specialized navigation systems.

[Enhanced recovery in thoracic surgery]. / Uskorennaya reabilitatsiya v torakal'noi khirurgii.

OBJECTIVE: To present an experience of adapting the accelerated rehabilitation protocol at the thoracic surgery department of the Moscow City Clinical Oncology Hospital No. 1. MATERIAL AND METHODS: An effectiveness of the accelerated rehabilitation program in the city oncology hospital was retrospectively analyzed for the period from February to December 2019. Lung resections were performed in 252 patients with median age 66 (59; 71) years and an equal ratio of men and women (124/128). Primary non-small cell lung cancer was noted in 194 (77%) patients, secondary malignant neoplasms of lungs - in 58 (23%) cases. ASA grading system of anesthetic risk was applied (American Society of Anesthesiologists): grade II - 56 (22.2%) patients, grade III - 203 (75.2%) patients, grade IV - 7 (2.8%) patients. RESULTS: Lobectomy was performed in 147 patients, segmentectomy - in 32, bilobectomy, pneumonectomy and marginal resection - in 1, 3 and 69 cases, respectively. Endoscopic operations made up 13.6% (n=20), 12.5% (n=4) and 78% (n=54). Postoperative 30-day complications occurred in 19 (7.5%) out of 252 patients (95% CI 4.9-11.5). Postoperative 30-day mortality was 1.98% (5 out of 252 patients, 95% CI 0.9-4.6). Median postoperative hospital-stay was 7 (6; 8) days. CONCLUSION: Implementation of fast track protocol requires time and the first results can be assessed after 6-12 months. Continuous monitoring of implementation of the protocol elements by all members of multidisciplinary team, analysis of complications and long-term results are required to realize all potential benefits of this program.
