Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
ВведениеСреди злокачественных новообразований ко-лоректальный рак занимает четвертую позицию по частоте. Ежегодно регистрируют около 1,2 млн но-вых случаев заболевания. Более чем у половины за-болевших развивается метастатическое поражение печени [1][2][3] и без соответствующего лечения лишь 0-2% из них преодолевают 5-летний рубеж выживаемости. В последнее десятилетие намети-лась положительная тенденция в лечении пациен-тов с метастатическим колоректальным раком (мКРР) печени. Современные режимы лекарствен-ной терапии, включающие иринотекан, оксали-платин, цетуксимаб и бевацизумаб, обеспечивают уровень ответа до 50-80%, повышают медиану вы-живаемости при нерезектабельном поражении до 12-24 мес и позволяют перевести опухоль из раз-ряда нерезектательных в резектабельные у 5-15% больных [4, 5].

Онкологическая эффективность радиочастотной абляции (рЧа) и ее место в структуре комбинированного лечения остаются предметом дискуссий на онкологических форумах и в публикуемых в мировой литературе исследо-ваниях. Цель работы -изучение хирургических и онкологических результатов лечения пациентов с метастатическим колоректальным раком печени методом рЧа в структуре комбинированного подхода. Материал и методы. использован проспективный анализ результатов лечения 76 пациентов с метастатическим колоректальным раком печени с примене-нием метода рЧа за период с 2004 по 2013 г. проведен унивариантный и мультивариантный анализ общей выживаемости. Результаты. Отрицательное влияние на общую 5-летнюю выживаемость по результатам унивариантного анализа оказы-вают локализация первичной опухоли в прямой кишке (36,2 и 7,2%; p=0,021), билобарное метастатическое поражение печени (35,9 и 15,4%; p=0,068); размер метастазов более 5 см (27,4% и 0; p=0,091), уровень CAE выше 4 норм (26,7 и 11,4%; p=0,09), выполнение рЧа одним из этапов двухэтапного хирургического вмешательства на печени (23,3 и 26,0%; p=0,09). Вывод. рЧа является эффективным методом локального противоопухолевого воздействия при метастатическом колоректальном раке. на отдаленную выживаемость после рЧа влияют размер коагулируемых метастазов, объем мета-статического поражения, уровень ракового эмбрионального антигена, выполнение абляции в рамках двухэтапного хирур-гического лечения. Ключевые слова: метастазы колоректального рака в печень, радиочастотная абляция.

Isolated pancreatic metastases of renal cell carcinoma can occur in decades after nephrectomy. Therefore, lifelong follow-up is necessary. Pancreatectomy for focal lesion is associated with good long-term outcome.
