In recent years, with the improvement of CT resolution, the reduction of radiation dose, the popularization of lung cancer screening and the enhancement of people's health awareness, the detection rate of lung nodules is higher and higher. Due to the close relationship between lung nodules and lung cancer, more and more attention has been paid to them. Although patients with early and middle stage lung cancer receive complete resection, all postoperative patients are at risk of recurrence and metastasis. Adjuvant or neoadjuvant therapy can improve the survival and reduce the recurrence and metastasis. Therefore, the multidisciplinary team, as the best model, provides a standardized and individualized plan for the diagnosis and treatment of lung nodules and lung cancer patients. However, in the clinical practice, the work efficiency of the multidisciplinary team is not high, and the participation rate of patients is low; therefore the multidisciplinary doctor model with thoracic surgeons as the mainstay is a reasonable alternative.
肺癌是最常见的恶性肿瘤之一，我国每年大约有60万人死于肺癌，因此愈发引起关注。由中华医学会胸心血管外科学会肺癌学组组织，首都医科大学宣武医院胸外科刘宝东起草，支修益组织国内相关专家在2014年10月至2014年11月通过讨论、电子邮件等形式，反复征求参审专家的意见，达成了影像引导射频消融治疗肺部肿瘤的专家共识现已公布，旨在规范操作技术、进行疗效评估、减少并发症和提高治疗效果。
Recently, World Health Organization/International Agency for Research on Cancer (WHO/IARC) published the World Cancer Report 2020. This report described the cancer burden of the world, the risk factors of cancer, biological process in cancer development and the prevention strategies of cancer. Based on current status of China’s cancer burden and prevention strategies, this paper briefly interpreted the key points of cancer prevention and control in the report.
ObjectiveThe clinical trial evidence and expert consensus in the airway management were systematically summarized in this guideline to provide clinical guidance for healthcare professionals.MethodsA total of 40 clinical questions were proposed by 32 experts, and 12 clinical questions were finally identified through the Delphi method and the PICO (patient, intervention, control, outcome) principle from 2019 to 2020. PubMed, Web of Science, Wanfang database and CNKI were searched from establishment of each database up to November, 2020. The evidence of 160 articles was graded according to GRADE method, including 18 in class A, 36 in class B, 69 in class C, and 37 in class D. Four symposiums were organized for discussion of the recommendations. Finally, 23 recommendations were made for these 12 clinical questions, among which 10 were strongly recommended and 13 were weakly recommended.ResultsSmoking cessation for at least 4 weeks, pulmonary function assessment and pulmonary rehabilitation exercise were recommended in the perioperative period, especially at least 1 week of pulmonary rehabilitation exercise for the patients with high risk factors. Anesthesia was maintained by inhalation or intravenous anesthesia. It was recommended to choose short acting drugs, monitor the depth of anesthesia and muscle relaxation during operation, and use protective ventilation strategy. Postoperative use of drugs and mechanical measures to prevent venous thromboembolism, the appropriate application of drainage tube, preemptive analgesia and multimodal analgesia for pain management were recommended. Inhaled corticosteroids with bronchodilators could be used in perioperative period to reduce airway hyperresponsiveness and postoperative cough.ConclusionFor perioperative airway management, smoking cessation, pulmonary function assessment and pulmonary rehabilitation exercise are recommended in the perioperative period. The rational use of anesthetic drugs and protective ventilation strategy are emphasized during the operations. Postoperative pain management and cough treatment should be strengthened, and drainage tube should be used properly.
Objective To study the distribution and drugresistance of pathogens isolated from patients who suffered from lower respiratory infections after thoracotomy and provide basis for rational use of antibiotics in clinical practice. Methods A total of 118 patients suffered from lower respiratory infections after thoracotomy in Beijing Lung Cancer Center and the Thoracic Surgery Department of Xuanwu Hospital between January 1,2006 and December 31, 2009. We performed a retrospective study on pathogens from their lower respiratory tract. Of these patients, 89 are male and 29 are female with a mean age of 64.6 years. Sputum specimens were obtained by sterile sputum collectors or bronchofibroscopes, and then were sent to microorganism laboratory immediately. Cytological screening was carried out before specimen inoculation. Bacterial culture, identification and drug sensitivity test were performed with routine methods. Results A total of 201 strains of pathogens from the lower respiratory tract were identified. There were 126(62.7%) strains of gramnegative bacilli, 66(32.8%) strains of grampositive cocci, and 9(4.5%) strains fungi. The four prevalent gramnegative bacilli strains with the highest isolating rate between 2006 and 2009 included 34(27.0%) strains of acinetobacters, 28(22.2%) strains of verdigris Pseudomonas, 19(15.1%) strains of Klebsiellas and 19(15.1%) strains of Escherichia coli. Verdigris Pseudomonas ranked first in isolating rate among prevalent gramnegative bacilli strains from 2006 to 2008, but it was replaced by cinetobacters (9 strains, 40.9%) in 2009. The most prevalent strains of grampositive cocci were staphylococcus aureus (35 strains, 53%) from 2006 to 2009. Gramnegative bacilli were most sensitive to imipenem and no grampositive cocci were resistant to vancomycin. Conclusion Gramnegative bacilli are the most common pathogens in lower respiratory infections after thoracotomy and show extremely high drugresistance rate. Drugresistance monitoring of pathogens should be promoted. It may contribute to rational antimicrobial therapy and effective control of infections.
