摘要
CT screening has markedly reduced the lung cancer mortality in high-risk population and increased the detection of early-stage pulmonary neoplasms, including multiple pulmonary nodules, especially those with a ground-glass appearance on CT. Multiple primary lung cancer (MPLC) constitutes a specific subtype of lung cancer with indolent biological behaviors, which is predominantly early-stage adenocarcinoma. Although MPLC progresses slowly with rare lymphatic metastasis, existence of synchronous lesions and distributed location of these nodules still pose difficulty for the management of such patients. One single operation is usually insufficient to eradicate all neoplastic lesions, whereas repeated surgical procedures bring about another dilemma: whether clinical benefits of surgical treatment outweigh loss of pulmonary function following multiple operations. Therefore, despite the anxiety for treatment among MPLC patients, whether and how to treat the patient should be assessed meticulously. Currently there is a heated discussion upon the timing of clinical intervention, operation mode and the application of local therapy in MPLC. Based on clinical experience of our multiple disciplinary team, we have summarized and commented on the evaluation, surgical treatment, non-surgical local treatment, targeted therapy and immunotherapy of MPLC in this article to provide further insight into this field.

Surgical operation is one of the significant parts of the comprehensive therapeutic methods of lung cancer. In the history of the development of lung cancer operation, scholars and predecessors at home and abroad have gradually established the current status of lung cancer operation and the framework of comprehensive treatment after continuous understanding of local anatomy of lung, continuous innovation of surgical equipment and continuous reform of surgical methods. In the continuous development and improvement of lung cancer surgical diagnosis and treatment procedures, a set of standardized diagnosis and treatment process of lung cancer screening, early diagnosis and treatment, standardized surgery process, rapid perioperative recovery, postoperative adjuvant treatment and follow-up has been formed. The achievements of lung cancer operation are achieved by scholars standing on the shoulders of giants. In the process of pioneering and innovating, we should go back and review the road that our predecessors have taken, and draw energy from it to continue to create new brilliance in lung cancer operation. In this paper, the evolution history of lung cancer surgery is summarized in order to improve the clinician's understanding of the history of lung cancer surgery.

Clinical studies have established the clinical application of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) adjuvant targeted therapy. Compared with chemotherapy, the high efficiency and low toxicity of targeted therapy increases the survival benefit of patients. Icotinib was the first EGFR-TKI with independent intellectual property rights in China and the third EGFR-TKI to be marketed in the world. In order to summarize the experience of icotinib and other EGFR-TKIs in the adjuvant treatment of non-small cell lung cancer and further standardize and guide the clinical application of icotinib, experts from the China International Exchange and Promotive Association for Medical and Health Care and the Guangdong Association of Thoracic Diseases have organized an expert consensus on the adjuvant treatment of non-small cell lung cancer with icotinib, which is expected to provide clinicians with evidence-based medical evidences for postoperative targeted drug using.

BACKGROUND@#Post-operative pneumonia (POP) is a common complication of lung cancer surgery, and muscular tissue oxygenation is a root cause of post-operative complications. However, the association between muscular tissue desaturation and POP in patients receiving lung cancer surgery has not been specifically studied. This study aimed to investigate the potential use of intra-operative muscular tissue desaturation as a predictor of POP in patients undergoing lung cancer surgery.@*METHODS@#This cohort study enrolled patients (≥55 years) who had undergone lobectomy with one-lung ventilation. Muscular tissue oxygen saturation (SmtO 2 ) was monitored in the forearm (over the brachioradialis muscle) and upper thigh (over the quadriceps) using a tissue oximeter. The minimum SmtO 2 was the lowest intra-operative measurement at any time point. Muscular tissue desaturation was defined as a minimum baseline SmtO 2 of <80% for >15 s. The area under or above the threshold was the product of the magnitude and time of desaturation. The primary outcome was the association between intra-operative muscular tissue desaturation and POP within seven post-operative days using multivariable logistic regression. The secondary outcome was the correlation between SmtO 2 in the forearm and that in the thigh.@*RESULTS@#We enrolled 174 patients. The overall incidence of muscular desaturation (defined as SmtO 2 < 80% in the forearm at baseline) was approximately 47.1% (82/174). The patients with muscular desaturation had a higher incidence of pneumonia than those without desaturation (28.0% [23/82] vs. 12.0% [11/92]; P = 0.008). The multivariable analysis revealed that muscular desaturation was associated with an increased risk of pneumonia (odds ratio: 2.995, 95% confidence interval: 1.080-8.310, P = 0.035) after adjusting for age, American Society of Anesthesiologists status, Assess Respiratory Risk in Surgical Patients in Catalonia score, smoking, use of peripheral nerve block, propofol, and study center.@*CONCLUSION@#Muscular tissue desaturation, defined as a baseline SmtO 2 < 80% in the forearm, may be associated with an increased risk of POP.@*TRIAL REGISTRATION@#No. ChiCTR-ROC-17012627.

Objective To observe the effect of calcified lymph nodes on video-assisted thoracoscopic surgery (VATS) lobectomy in the chronic obstructive pulmonary disease (COPD) patients with lung cancer. Methods A retrospective analysis was conducted on the COPD patients with lung cancer who underwent VATS lobectomy in the Department of Thoracic Surgery in the First Affiliated Hospital of Hebei North University from May 2014 to May 2018.The patients were assigned into a calcified lymph node group and a control group according to the presence or absence of calcified lymph nodes in CT,and the size,morphology,and calcification degree of the lymph nodes were recorded.The operation duration,intraoperative blood loss,chest tube retention time,hospitalization days,and overall complication rate were compared between the two groups. Results The 30 patients in the calcified lymph node group included 17 patients with one calcified lymph node and 13 patients with two or more calcified lymph nodes,and a total of 65 calcified lymph nodes were recorded.The calcified lymph nodes with the size ≤5 mm were the most common (53.8%),and complete calcification was the most common form (55.4%) in lymph node calcification.The mean operation duration had no significant difference between the calcified lymph node group and the control group (t=-1.357,P=0.180).The intraoperative blood loss (t=-2.646,P=0.010),chest tube retention time (t=-2.302,P=0.025),and hospitalization days (t=-2.274,P=0.027) in the calcified lymph node group were higher than those in the control group. Conclusion Calcified lymph nodes increase the difficulty and risk of VATS lobectomy in the COPD patients with lung cancer.The findings of this study are conducive to predicting the perioperative process of VATS lobectomy.

Lung cancer is the highest cancer-related mortality rate in the world, and is one of the most common malignancies. The standard treatment for early-stage non-small cell lung cancer (NSCLC) is radical lobectomy, while recent studies have found that sub-lobectomy of pulmonary nodules (≤2 cm) is not inferior to lobectomy and even improve the prognosis of the patients. These important findings will effectively and positively promote the formation of consensus and principles of wedge resection of pulmonary nodules (≤2 cm) in the field of thoracic surgery. The purpose of this study is to present a national expert consensus on wedge resection of pulmonary nodules (≤2 cm) in the field of thoracic surgery. The experts from Editorial Committee of Consensus on Wedge Resection of Lung Nodules (≤2 cm) (2023 Edition) jointly participated in the revision work. According to the clinical progress about the wedge resection of pulmonary nodules (≤2 cm) at home and abroad during recent years, experts jointly wrote Wedge Resection of Pulmonary Nodules (≤2 cm): a Consensus Statement by Specialists of Thoracic Surgery (2023 Edition), in combination with the homogeneous treatment principles of wedge resection in the field of thoracic surgery in China. This consensus was summarized from the following aspects: (1) Indications of wedge resection of pulmonary nodules (≤2 cm); (2) Resection range of pulmonary nodules (≤2 cm) required for wedge resection; (3) Excisable pulmonary nodules (≤2 cm) for wedge resection. This consensus finally put forward 8 recommended opinions, and sorted out 5 opinions which were still controversial and needed more evidence. The integrated opinions were generated through the discussion held among the experts of thoracic surgery from all over the country, making wedge resection of pulmonary nodules (≤2 cm) more appropriate for China and more standardized and homogeneous for clinical practice. In the future, more relevant researches should be accumulated based on the characteristics of lung cancer and its diagnosis and treatment in China, optimizing the treatment of pulmonary nodules (≤2 cm).

BACKGROUND@#Lung cancer is one of the most common malignant tumors in the world. The accuracy of intraoperative frozen section (FS) in the diagnosis of lung adenocarcinoma infiltration cannot fully meet the clinical needs. The aim of this study is to explore the possibility of improving the diagnostic efficiency of FS in lung adenocarcinoma by using the original multi-spectral intelligent analyzer.@*METHODS@#Patients with pulmonary nodules who underwent surgery in the Department of Thoracic Surgery, Beijing Friendship Hospital, Capital Medical University from January 2021 to December 2022 were included in the study. The multispectral information of pulmonary nodule tissues and surrounding normal tissues were collected. A neural network model was established and the accuracy of the neural network diagnostic model was verified clinically.@*RESULTS@#A total of 223 samples were collected in this study, 156 samples of primary lung adenocarcinoma were finally included, and a total of 1,560 sets of multispectral data were collected. The area under the curve (AUC) of spectral diagnosis in the test set (10% of the first 116 cases) of the neural network model was 0.955 (95%CI: 0.909-1.000, P<0.05), and the diagnostic accuracy was 95.69%. In the clinical validation group (the last 40 cases), the accuracy of spectral diagnosis and FS diagnosis were both 67.50% (27/40), and the AUC of the combination of the two was 0.949 (95%CI: 0.878-1.000, P<0.05), and the accuracy was 95.00% (38/40).@*CONCLUSIONS@#The accuracy of the original multi-spectral intelligent analyzer in the diagnosis of lung invasive adenocarcinoma and non-invasive adenocarcinoma is equivalent to that of FS. The application of the original multi-spectral intelligent analyzer in the diagnosis of FS can improve the diagnostic accuracy and reduce the complexity of intraoperative lung cancer surgery plan. .

BACKGROUND@#Pre-operative accuracy of subcentimeter ground glass nodules (SGGNs) is a difficult problem in clinical practice, but there are few clinical studies on the benign and malignant prediction model of SGGNs. The aim of this study was to help identify benign and malignant lesions of SGGNs based on the imaging features of high resolution computed tomography (HRCT) and the general clinical data of patients, and to build a risk prediction model.@*METHODS@#This study retrospectively analyzed the clinical data of 483 patients with SGGNs who underwent surgical resection and were confirmed by histology from the First Affiliated Hospital of University of Science and Technology of China from August 2020 to December 2021. The patients were divided into the training set (n=338) and the validation set (n=145) according to 7:3 random assignment. According to the postoperative histology, they were divided into adenocarcinoma group and benign lesion group. The independent risk factors and models were analyzed by univariate analysis and multivariate Logistic regression. The receiver operator characteristic (ROC) curve was constructed to evaluate the model differentiation, and the calibration curve was used to evaluate the model consistency. The clinical application value of the decision curve analysis (DCA) evaluation model was drawn, and the validation set data was substituted for external verification.@*RESULTS@#Multivariate Logistic analysis screened out patients' age, vascular sign, lobular sign, nodule volume and mean-CT value as independent risk factors for SGGNs. Based on the results of multivariate analysis, Nomogram prediction model was constructed, and the area under ROC curve was 0.836 (95%CI: 0.794-0.879). The critical value corresponding to the maximum approximate entry index was 0.483. The sensitivity was 76.6%, and the specificity was 80.1%. The positive predictive value was 86.5%, and the negative predictive value was 68.7%. The benign and malignant risk of SGGNs predicted by the calibration curve was highly consistent with the actual occurrence risk after sampling 1,000 times using Bootstrap method. DCA showed that patients showed a positive net benefit when the predictive probability of the predicted model probability was 0.2 to 0.9.@*CONCLUSIONS@#Based on preoperative medical history and preoperative HRCT examination indicators, the benign and malignant risk prediction model of SGGNs was established to have good predictive efficacy and clinical application value. The visualization of Nomogram can help to screen out high-risk groups of SGGNs, providing support for clinical decision-making.

BACKGROUND@#Lung cancer is the first leading cause of morbidity and mortality among the malignant tumors, which has become a hot issue in current research. Clinically, lung cancer is divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) according to the pathological types. NSCLC includes adenocarcinoma, squamous cell carcinoma and other types of lung cancer, accounting for about 80% of all lung cancer. Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE), which is a recognized complication in lung cancer patients with higher morbidity and mortality. The aim of this study is to determine the incidence of DVT and reveal the risk factors for DVT in the postoperative patients with lung cancer.@*METHODS@#We collected 83 postoperative patients with lung cancer admitted to the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital from December 2021 to December 2022. All these patients were examined by color Doppler ultrasound of lower extremity vein upon admission and after operation to analyze the incidence of DVT. In order to explore the possible risk factors for DVT in these patients, we further analyzed the correlations between DVT and their clinical features. At the same time, the changes of coagulation function and platelet were monitored to investigate the value of blood coagulation in the patients with DVT.@*RESULTS@#DVT occurred in 25 patients after lung cancer operation, and the incidence rate of DVT was 30.1%. Further analysis found that the incidences of postoperative lower limb DVT were higher in lung cancer patients of stage III+IV or over 60 years of age (P=0.031, P=0.028). D-Dimer level in patients with thrombosis was significantly higher than that in non-thrombus patients on the 1st, the 3rd, and the 5th day after operation (P<0.05), and there was no significant difference in platelets and fibrinogen (FIB) (P>0.05).@*CONCLUSIONS@#The overall incidence of DVT in our center after lung cancer patients operation was 30.1%. Late-stage and older postpatients were more likely to develop DVT, and these patients with higher D-Dimer values should be considered the possibility of VTE events.

Lung cancer ranked the highest incidence rate and mortality among people over 60 years old in China. With the increasing social population and incidence of lung cancer, the treatment of elderly lung cancer patients has become a major concern. Due to the improvement of surgical techniques and the application of enhanced recovery after surgery in thoracic surgery, more elderly patients could tolerate surgical treatment. At the same time, with the improvement of health awareness and the popularization of early diagnosis and screening, more lung cancer can be detected at the early stage. However, considering the organ dysfunction, various complications, physical weakness and other factors of elderly patients, it is important to provide individualized surgical treatment for the elderly. Therefore, based on the latest research progress worldwide, the experts in relevant fields have developed this consensus which contributes to guide the preoperative evaluation, surgical strategy, intraoperative anesthesia management, and postoperative management for elderly patients of lung cancer. .

BACKGROUND@#For resectable non-small cell lung cancer (NSCLC), the CheckMate-816 study demonstrated that neoadjuvant chemoimmunotherapy increased the rate of complete pathologic response (pCR) by 21.8% compared with chemotherapy alone and resulted in a significant benefit in event-free survival (EFS). This study aimed to investigate the safety and feasibility of this approach in the real world.@*METHODS@#Clinical data from patients with NSCLC who underwent surgery after neoadjuvant chemoimmunotherapy or chemotherapy alone in two centers were analyzed retrospectively, and subgroup analyses were performed for the chemoimmunotherapy group according to treatment cycle. The primary study endpoints were EFS and major pathologic response (MPR), and the secondary study endpoints were pCR, overall survival (OS), treatment-related adverse events (TRAEs), and surgery-related metrics.@*RESULTS@#As of April 2023, 89 patients had been enrolled, including 54 in the chemoimmunotherapy group and 35 in the chemotherapy alone group. MPR was achieved in 31 (57.4%) and 5 (14.3%) patients in the chemoimmunotherapy group and chemotherapy alone group, respectively (OR=8.09, 95%CI: 2.72-24.04, P<0.001); pCR was achieved in 25 (46.3%) patients in the chemoimmunotherapy group and no patient in the chemotherapy alone group (P<0.001). The median follow-up time was 22.1 months. At 24 months, the EFS rates of the chemoimmunotherapy group and the chemotherapy alone group were 77.0% and 56.7%, respectively (P=0.026), and the OS rates were 87.1% and 67.7%, respectively (P=0.020). In the neoadjuvant chemoimmunotherapy group, there was no significant difference between the 1-2 cycles and 3-5 cycles groups in terms of operation time, intraoperative blood loss, and postoperative complications.@*CONCLUSIONS@#Neoadjuvant chemoimmunotherapy was more effective than chemotherapy alone and did not increase the risk associated with surgery. An increase in the number of cycles of neoadjuvant chemoimmunotherapy had no significant effect on the difficulty of surgery.

BACKGROUND@#The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy.@*METHODS@#Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes.@*RESULTS@#A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group.@*CONCLUSIONS@#Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

El hemangioendotelioma epiteloide hepático (HEHE) es un tumor vascular raro de menor malignidad que el hemangiosarcoma. En los poco frecuentes casos unilobulares, puede indicarse hepatectomía parcial con riesgo de recurrencia agresiva; en enfermedad hepática extensa, incluso con compromiso extrahepático, el trasplante hepático ha resultado efectivo. Las metástasis son más frecuentes en pulmón,peritoneo, ganglios linfáticos, bazo y sistema nervioso. Se presenta el caso de un adolescente asintomático con HEHE con metástasis pulmonares y compromiso ganglionar abdominal que recibió trasplante hepático con evolución favorable.
Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor of less malignancy than hemangiosarcoma. In the rare unilobar cases, partial hepatectomy may be indicated with risk of aggressive recurrence; in extensive liver disease, even with extrahepatic involvement, liver transplantation has been performed successfully. Metastases are more common in the lung, peritoneum, lymph nodes, spleen, and nervous system. We present the case of an asymptomatic adolescent with HEHE with lung metastases and abdominal lymph node involvement who received a liver transplant with a favorable outcome.

Resumen Objetivos: Presentar caso clínico y revisión de la literatura sobre asociación de tumores poco frecuentes compatibles con diagnóstico de tríada de Carney. Paciente y Métodos: Revisión de ficha clínica de paciente de sexo femenino de 39 años de edad con antecedentes de asma, quien acude a servicio de urgencias por síntomas respiratorios. En estudio con imágenes se evidencia masa pulmonar en lóbulo superior derecho probablemente hamartoma y masa en la bifurcación carotídea izquierda compatible con posible paraganglioma. Se completó el estudio con endoscopia digestiva alta sin evidencia de tumor gástrico y PET-CT (tomografía de emisión de positrones-tomografía computarizada) que descartó otras lesiones. Resultados: La paciente fue sometida a resección quirúrgica de ambos tumores (pulmonar y carotídeo). En estudio histopatológico diferido, se plantean los diagnósticos de paraganglioma carotideo y hamartoma pulmonar, el cual, luego de una segunda revisión histopatológica, es corregido a condroma pulmonar. Discusión: La tríada de Carney se compone por la asociación de al menos 2 de 3 tumores: tumor estromal gastrointestinal (GIST), paraganglioma extra-adrenal y condroma pulmonar. Su expresión es variable, coexistiendo en forma completa en solo el 22% de los casos. Conclusión: Los pacientes con sospecha de tríada de Carney deben recibir evaluación multidisciplinaria, estudio completo en búsqueda de tumores asociados y seguimiento a largo plazo por posibles recurrencias o metástasis.
Objective: To present a clinical case and review of the literature on the infrequent association of pulmonary and extra thoracic tumors compatible with Carney's triad. Patient and Methods: Review of clinical records of a 39 years-old female patient with history of asthma who presented in the emergency department with respiratory symptoms. An imaging study showed a pulmonary mass in the right upper lobe with the aspect of hamartoma and a mass in the left carotid artery bifurcation compatible with a possible paraganglioma. Upper gastrointestinal endoscopy showed no evidence of gastric tumor and a PET-CT (Positron Emission Tomography - Computed Tomography) excluded other lesions. Results: Patient underwent surgical resection of both tumors (pulmonary and carotid). Diagnosis of carotid paraganglioma and pulmonary hamartoma were stated by histopathology. However, lung tumor after a second pathological analysis was confirmed to be a pulmonary chondroma. Discussion: Carney's triad is defined by the association of at least 2 of 3 tumors: Gastrointestinal Stromal Tumor (GIST), extraadrenal paraganglioma and pulmonary chondroma. Its expression is variable, coexisting completely in only 22% of cases. Conclusion: Patients with suspected Carney's triad should receive a multidisciplinary assessment, a complete study searching associated tumors and long-term follow-up for recurrences or metastases.

BACKGROUND@#The first-line treatment for lung cancer is surgical resection, and one-lung ventilation (OLV) is the most basic anesthetic management method in lung surgery. During OLV, inflammatory cytokines are released in response to the lung tissue damage and promote local and contralateral lung damage through the systemic circulation. We designed a randomized, prospective study to evaluate the effect of the urinary trypsin inhibitor (UTI) ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer.@*METHODS@#Adult patients aged 19 to 70 years, who were scheduled for video-assisted thoracic lobectomy surgery to treat lung cancer between May 2020 and August 2020, were enrolled in this randomized, prospective study. UTI (300,000 units) mixed with 100 mL of normal saline in the ulinastatin group and 100 mL of normal saline in the control group was administered over 1 h after inducing anesthesia.@*RESULTS@#The baseline (T0) interferon-γ (IFN-γ)/interleukin-4 (IL-4) ratio was not different between the groups (6941.3 ± 2778.7 vs. 6954.3 ± 2752.4 pg/mL, respectively; P > 0.05). The IFN-γ/IL-4 ratio was significantly higher in ulinastatin group at 30 min after entering the recovery room than control group (20,148.2 ± 5054.3 vs. 6674.0 ± 2963.6, respectively; adjusted P < 0.017).@*CONCLUSION@#Administering UTI attenuated the anti-inflammatory response, in terms of INF-γ expression and the IFN-γ/IL-4 ratio, after video-assisted thoracic surgery in lung cancer patients.@*TRIAL REGISTRATION@#Clinical Research Information Service of Korea National Institute of Health (CRIS), KCT0005533.

BACKGROUND@#The localization of pulmonary nodules is related to whether the lesions can be found and removed accurately and quickly. It is an important link for the success of minimally invasive video-assisted thoracic surgery (VATS). This study investigated the feasibility of medical glue localization under VATS video-assisted thoracoscopic computed tomography (CT) guidance for single pulmonary nodule and more than two pulmonary nodules, and compared with the accuracy and safety of single nodule localization.@*METHODS@#A retrospective analysis of the clinical data of patients who underwent unilateral CT-guided medical glue localization before VATS from November 2018 to March 2021 were performed, the patients was divided into multiple pulmonary nodules group (localized nodules ≥2) and single pulmonary nodule group according to the number of localized nodules. The localization time, success rate and complication rate of the two groups were compared.@*RESULTS@#There were 126 nodules in the two groups, including 62 in single pulmonary nodule group and 64 in multiple pulmonary nodules group. The average single nodule localization time was (13.23±4.5) min in single pulmonary nodule group and (10.52±2.8) min in multiple pulmonary nodules group, the difference between the two groups is statistically significant (P<0.05). The localization success rate of single pulmonary nodule group and multiple pulmonary nodules group were 100% and 98.4% separately, the difference between the two groups was not statistically significant (P>0.05). All VATS were successfully completed after localization. The incidence of pneumothorax was higher in multiple pulmonary nodules group than in single pulmonary nodule group (P=0.07).@*CONCLUSIONS@#Compared with localization of single lung nodule, unilateral CT-guided medical glue localization for multiple pulmonary nodules before VATS is also feasible and accuracy, it is worthy of clinical application. But the higher rate of pneumothorax should be paid attention to.

BACKGROUND@#Chronic obstructive pulmonary diseases (COPD) affects 45%-63% of lung cancer patients worldwide. Lung cancer patients complicated with COPD have decreased cardiopulmonary function and increased perioperative risk, and their postoperative exercise endurance and lung function are significantly lower than those with conventional lung cancer. Previous studies have shown that postoperative exercise training can improve the exercise endurance of unselected lung cancer patients, but it is unclear whether lung cancer patients with COPD can also benefit from postoperative exercise training. This study intends to explore the effects of postoperative exercise training on exercise endurance, daily activity and lung function of lung cancer patients with COPD.@*METHODS@#Seventy-four patients with non-small cell lung cancer (NSCLC) complicated with COPD who underwent pneumonectomy in the lung cancer center of West China Hospital of Sichuan University from August 5, 2020 to August 25, 2021 were prospectively analyzed. They were randomly divided into exercise group and control group; The patients in the two groups received routine postoperative rehabilitation in the first week after operation, and the control group was given routine nursing from the second week. On this basis, the exercise group received postoperative exercise rehabilitation training for two weeks. Baseline evaluation was performed 3 days before operation and endpoint evaluation was performed 3 weeks after operation.@*RESULTS@#The exercise endurance, daily activity and pulmonary function test results of the two groups decreased from baseline to the end point. However, after the operation and intervention program, the maximum oxygen consumption of Cardiopulmonary Exercise Test and the walking distance of 6-Minute Walking Test in the exercise group were significantly better than those in the control group [(13.09±1.46) mL/kg/min vs (11.89±1.38) mL/kg/min, P=0.033; (297±46) m vs (243±43) m, P=0.041]. The average number of we-chat steps in the exercise group was also significantly better than that in the control group (4,381±397 vs 3,478±342, P=0.035). Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) in the exercise group were better than those in the control group, but the difference did not reach a statistically significant level [(1.76±0.19) L vs (1.60±0.28) L, P=0.084; (1.01±0.17) L vs (0.96±0.21) L, P=0.467].@*CONCLUSIONS@#Postoperative exercise rehabilitation training can improve exercise endurance and daily activity ability of patients with lung cancer complicated with COPD and promote postoperative rehabilitation.

BACKGROUND@#To investigate the correlation between the reduction of lung volume and the degree of lung function damage after lobectomy.@*METHODS@#A total of 131 patients (72 males and 59 females) who underwent thoracoscopic lobectomy in the First Affiliated Hospital of Suzhou University from January 2019 to July 2020 (including thoracoscopic resection of left upper lobe, left lower lobe, right upper lobe, right middle lobe and right lower lobe). In order to compare the difference between postoperative pulmonary function and preoperative pulmonary function, the pulmonary function measurements were recorded at 7 days before operation, and 3 months, 6 months and 1 year after operation. Forced expiratory volume in 1 second (FEV1) was used as the main evaluation parameter of pulmonary function. The original lung volume and the remaining lung volume at each stage were calculated by Mimics Research 19.0 software. The correlation between lung volume and lung function was analyzed.@*RESULTS@#FEV1 in postoperative patients was lower than that before operation, and the degree of decline was positively correlated with the resection volume of lung lobes (the maximum value was shown in the left lower lobe group). Significantly, there was no significant difference in the degree of pulmonary function reduction between 3 months, 6 months and 1 year after operation.@*CONCLUSIONS@#The decrease of lung tissue volume after lobectomy is the main reason for the decrease of lung function, especially in the left lower lobe. And 3 months after lobectomy can be selected as the evaluation node of residual lung function.
