ABSTRACT
@#Although surgical resection remains to be the best treatment strategy for stageⅠnon-small cell lung cancer (NSCLC), percutaneous thermal ablation offers an important option for patients who are unable to undergo surgical resection. Currently, there are three main thermal ablation methods used in the treatment of lung cancer, including radiofrequency ablation (RFA), microwave ablation (MWA) and argon-helium cryoablation (AHC). With the improvement of technique and the accumulation of experience in the treatment of lung cancer, some limitations are disclosed in the initial application of RFA, such as heat sink effect, skin burns and rapid carbonization. These shortcomings have been overcome in the development of MWA and AHC. The feasibility and safety of thermal ablation for the treatment of lung cancer has been demonstrated and its efficacy has been significantly improved (especially for the tumour diameter≤3 cm). This article will focus on the application and recent research developments of these ablation techniques in the treatment of lung cancer.
ABSTRACT
Objective To evaluate the short-term outcomes and postoperative inflammatory cytokine changes in patients with lung cancer treated with robot-assisted thoracoscopic surgery (RATS) versus video-assisted thoracoscopic surgery (VATS). Methods A total of 270 patients with lung cancer treated by minimally invasive surgery were selected for the study, and the surgical procedures were selected according to the patients' economic conditions and preferences. Among them, 132 patients completed the operation through RATS, and 138 patients completed the operation through VATS. The clinical data of the two groups were compared. Results All patients successfully completed radical lung cancer surgery, and no perioperative deaths were reported. Intraoperative bleeding, postoperative drainage time, postoperative hospital stay, number of lymph nodes dissected, and number of lymph nodes dissected groups were more advantageous in the RATS group compared with the VATS group (P < 0.05). In terms of operative time, total postoperative chest drainage, and hospitalization cost, the VATS group had an advantage (P < 0.05). The postoperative levels of CRP, PCT, IL-6, IL-8, IL-10, and TNF-α increased in both groups, compared with preoperative levels, and the increases in the RATS group were lower than those in the VATS group. Conclusion RATS offers technical and short-term efficacy advantages for the treatment of lung cancer but comes with the disadvantage of high cost. Post-operative inflammatory cytokine elevation is lower in the RATS group, and inflammatory response to the organism is less severe.
ABSTRACT
Objective To systematically evaluate the effect of sequence of pulmonary artery and vein transection in thoracoscopic lobectomy on the efficacy and safety of patients with non-small cell lung cancer. Methods PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched for the researches on The post-operative efficacy of pulmonary arteriovenous and pulmonary vein resection sequence in thoracoscopic lobectomy for non-small cell lung cancer. The retrieval time is from the database construction to May 2022. Meta-analysis was performed using RevMan 5.4 software. Results Eight articles were included, including 3 randomized controlled studies and 5 cohort studies, with a total of 1810 patients. Meta-analysis results showed that: The operative time (MD=13.34, 95%CI(7.36, 19.32), P < 0.0001) and intraoperative blood loss (MD=45.29, 95%CI(40.24, 50.35), P < 0.0001) in the group with priority pulmonary vein resection were significantly higher than those in the group with priority pulmonary vein resection. The difference was statistically significant. However, the benefits of OS (HR=1.34, 95%CI (1.12, 1.60), P=0.001) and DFS (HR=1.44, 95%CI(1.18, 1.76), P=0.0003) in the group of priority pulmonary vein transection were significantly better than those in the group of priority pulmonary artery transection, with statistically significant differences. Conclusion Priority pulmonary vein transection during thoracoscopic lobectomy effectively improved patients' OS and DFS, resulting in higher survival benefit for patients with non-small cell lung cancer, but intraoperative bleeding and operation time are more than those with priority pulmonary artery transection.
ABSTRACT
Objective To compare the perioperative efficacy and safety of da Vinci robot-assisted thoracoscopic surgery (RATS) for treatment of anterior mediastinal tumors through subxiphoid versus lateral thoracic approaches under the laryngeal mask anesthesia. Methods We retrospectively analyzed the clinical data of 102 patients with anterior-mediastinal tumors treated by RATS under laryngeal mask anesthesia completed by the same operator. Forty-five patients underwent the subxiphoid approach (subxiphoid group), and 57 patients were treated with the lateral thoracic approach (lateral thoracic group). The operating time, intraoperative bleeding, and total postoperative drainage volume in the two groups were compared and analyzed. Results All patients successfully completed resection of the anterior mediastinal tumor without the occurrence of perioperative death. In terms of total postoperative drainage volume, postoperative drainage time, postoperative hospital stay, and VAS pain on postoperative days 2 and 3, the subxiphoid group was more advantages (P < 0.05). No statistically significant difference was found between the two groups in terms of operative time, docking time, total operative time, intraoperative bleeding volume, postoperative day 1 VAS pain score, or postoperative complications (P > 0.05). Conclusion The subxiphoid approach of RATS is safe and feasible for resection of anterior mediastinal tumors. Compared with the lateral thoracic approach, the subxiphoid approach has advantages in terms of rapid postoperative recovery and postoperative pain.
ABSTRACT
@#Objective To compare the mortality in lung cancer patients infected with coronavirus disease 2019 (COVID-19) versus other cancer patients infected with COVID-19. Methods A computer search of PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang database, VIP database and CNKI database was conducted to compare the mortality of lung cancer and other cancers patients infected with COVID-19 from the inception to December 2021. Two thoracic surgeons independently screened the literature, extracted data, and then cross-checked the literature. After evaluating the quality of the included literature, a meta-analysis was performed on the literature using Review Manager 5.4 software. Results A total of 12 retrospective cohort studies were included, covering 3 065 patients infected with COVID-19, among whom 340 patients suffered from lung cancer and the remaining 2 725 patients suffered from other cancers. Meta-analysis results showed that the lung cancer patients infected with COVID-19 had a higher mortality (OR=1.58, 95%CI 1.24 to 2.02, P<0.001). Subgroup analysis results showed that the mortality of two groups of patients in our country was not statistically different (OR=0.90, 95%CI 0.49 to 1.65, P=0.72). Whereas, patients with lung cancer had a higher mortality than those with other cancers in other countries (Brazil, Spain, USA, France, Italy, UK, Netherlands) (OR=1.78, 95%CI 1.37 to 2.32, P<0.001). Conclusion There is a negligible difference in mortality between lung cancer and other cancers patients who are infected with COVID-19 in our country; while a higher mortality rate is found in lung cancer patients in other countries. Consequently, appropriate and positive prevention methods should be taken to reduce the risk of infecting COVID-19 in cancer patients and to optimize the management of the infected population.
ABSTRACT
@#Objective To systematically evaluate the clinical efficacy and adverse reactions of paclitaxel and carboplatin with or without bevacizumab in the treatment of non-small cell lung cancer (NSCLC). Methods The databases including PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM were searched from inception to October 2022 to collect randomized controlled trials of the clinical efficacy of paclitaxel and carboplatin with or without bevacizumab for the treatment of NSCLC. RevMan 5.4 software was used for meta-analysis. Results Eight randomized controlled trials were enrolled, involving a total of 1 724 patients. Meta-analysis showed that for the treatment of NSCLC, the disease control rate, overall response rate, 1-year survival rate, and 2-year survival rate were higher in the trial group (paclitaxel and carboplatin combined with bevacizumab) than those in the control group (paclitaxel and carboplatin) (P<0.05); however, the incidences of the adverse reactions, such as leukopenia, hemorrhage, proteinuria and hypertension, etc, were higher in the trial group than those in the control group (P<0.05). There were no statistical differences between the trial group and the control group in the incidences of fatigue, thrombocytopenia, neutropenia or hyponatremia, etc (P>0.05). In addition, the median progression-free survival and overall survival were longer in the trial group than those in the control group. Conclusion For the treatment of NSCLC, paclitaxel and carboplatin combined with bevacizumab is superior in terms of disease control, overall response and prolonging patient survival, etc, but will be associated with more adverse reactions.
ABSTRACT
@#Objective To systematically evaluate the efficacy and safety of jejunostomy tube versus nasojejunal tube for enteral nutrition after radical resection of esophageal cancer. Methods PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched to collect the clinical effects of jejunostomy tube versus nasojejunal nutrition tube after radical resection of esophageal cancer from inception to October 2021. Meta-analysis was performed using RevMan 5.4 software. Results Twenty-six articles were included, including 17 randomized controlled studies and 9 cohort studies, with a total of 35 808 patients. Meta-analysis results showed that: in the jejunostomy tube group, the postoperative exhaust time (MD=–4.27, 95%CI –5.87 to –2.66, P=0.001), the incidence of pulmonary infection (OR=1.39, 95%CI 1.06 to 1.82, P=0.02), incidence of tube removal (OR=0.11, 95%CI 0.04 to 0.30, P=0.001), incidence of tube blockage (OR=0.47, 95%CI 0.23 to 0.97, P=0.04), incidence of nasopharyngeal discomfort (OR=0.04, 95%CI 0.01 to 0.13, P=0.001), the incidence of nasopharyngeal mucosal damage (OR=0.13, 95%CI 0.04 to 0.42, P=0.008), the incidence of nausea and vomiting (OR=0.20, 95%CI 0.08 to 0.47, P=0.003) were significantly shorter or lower than those of the nasojejunal tube group. The postoperative serum albumin level (MD=5.75, 95%CI 5.34 to 6.16, P=0.001) was significantly better than that of the nasojejunal tube group. However, the intraoperative operation time of the jejunostomy tube group (MD=13.65, 95%CI 2.32 to 24.98, P=0.02) and the indent time of the postoperative nutrition tube (MD=17.81, 95%CI 12.71 to 22.91, P=0.001) were longer than those of the nasojejunal nutrition tube. At the same time, the incidence of postoperative intestinal obstruction (OR=6.08, 95%CI 2.55 to 14.50, P=0.001) was significantly higher than that of the nasojejunal tube group. There were no statistical differences in the length of postoperative hospital stay or the occurrence of anastomotic fistula between the two groups (P>0.05). Conclusion In the process of enteral nutrition after radical resection of esophageal cancer, jejunostomy tube has better clinical treatment effect and is more comfortable during catheterization, but the incidence of intestinal obstruction is higher than that of traditional nasojejunal tube.
ABSTRACT
@#Objective To evaluate the efficacy and safety of robot-assisted thymectomy (RATS) versus video-assisted thoracoscopic thymectomy (VATS). Methods Web of Science, PubMed, EMbase, The Cochrane Library, Wanfang, VIP and CNKI databases were searched by computer from inception to February 2022. Relevant literatures that compared the efficacy and safety of RATS with those of VATS were screened. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included cohort studies, and Review Manager 5.4 software was utilized to perform a meta-analysis. Results A total of 16 retrospective cohort studies were included, covering a total of 1 793 patients (874 patients in the RATS group and 919 patients in the VATS group). The NOS scores of the included studies were≥7 points. Meta-analysis results revealed that RATS had less intraoperative bleeding (MD=−22.45, 95%CI −34.16 to −10.73, P<0.001), less postoperative chest drainage (MD=−80.29, 95%CI −144.86 to −15.72, P=0.010), shorter postoperative drainage time (MD=−0.69, 95%CI −1.08 to −0.30, P<0.001), shorter postoperative hospital stay (MD=−1.14, 95%CI −1.55 to −0.72, P<0.001) and fewer conversion to thoractomy (OR=0.40, 95%CI 0.23 to 0.69, P=0.001) than VATS; whereas, the operative time (MD=8.37, 95%CI −1.21 to 17.96, P=0.090), incidence of postoperative myasthenia gravis (OR=0.85, 95%CI 0.52 to 1.40, P=0.530), overall postoperative complications rate (OR=0.80, 95%CI 0.42 to 1.50, P=0.480) and tumour size (MD=−0.18, 95%CI −0.38 to 0.03, P=0.090) were not statistically different between the two groups. Conclusion In the aspects of intraoperative bleeding, postoperative chest drainage, postoperative drainage time, postoperative hospital stay and conversion to thoracotomy, RATS has unique advantages over the VATS.
ABSTRACT
@#Objective To systematically evaluate the accuracy of endoscopy-based artificial intelligence (AI)-assisted diagnostic systems in the diagnosis of early-stage esophageal cancer and provide a scientific basis for its diagnostic value. Methods PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang database, VIP database and CNKI database were searched by computer to search for the relevant literature about endoscopy-based AI-assisted diagnostic systems for the diagnosis of early esophageal cancer from inception to March 2022. The QUADAS-2 was used for quality evaluation of included studies. Meta-analysis of the literature was carried out using Stata 16, Meta-Disc 1.4 and RevMan 5.4 softwares. A bivariate mixed effects regression model was utilized to calculate the combined diagnostic efficacy of the AI-assisted system and meta-regression analysis was conducted to explore the sources of heterogeneity. Results A total of 17 articles were included, which consisted of 13 retrospective cohort studies and 4 prospective cohort studies. The results of the quality evaluation using QUADAS-2 showed that all included literature was of high quality. The obtained meta-analysis results revealed that the AI-assisted system in the diagnosis of esophageal cancer presented a combined sensitivity of 0.94 (95%CI 0.91 to 0.96), a specificity of 0.85 (95%CI 0.74 to 0.92), a positive likelihood ratio of 6.28 (95%CI 3.48 to 11.33), a negative likelihood ratio of 0.07 (95%CI 0.05 to 0.11), a diagnostic odds ratio of 89 (95%CI 38 to 208) and an area under the curve of 0.96 (95%CI 0.94 to 0.98). Conclusion The AI-assisted diagnostic system has a high diagnostic value for early stage esophageal cancer. However, most of the included studies were retrospective. Therefore, further high-quality prospective studies are needed for validation.
ABSTRACT
@# Objective To systematically evaluate the application effect of CT-guided Hook-wire localization and CT-guided microcoil localization in pulmonary nodules surgery. Methods The literatures on the comparison between CT-guided Hook-wire localization and CT-guided microcoil localization for pulmonary nodules were searched in PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP and CNKI databases from the inception to October 2021. Review Manager (version 5.4) software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of studies. Results A total of 10 retrospective cohort studies were included, with 1 117 patients including 473 patients in the CT-guided Hook-wire localization group and 644 patients in the CT-guided microcoil localization group. The quality of the studies was high with NOS scores>6 points. The result of meta-analysis showed that the difference in the localization operation time (MD=0.14, 95%CI −3.43 to 3.71, P=0.940) between the two groups was not statistically significant. However, the localization success rate of the Hook-wire group was superior to the microcoil group (OR=0.35, 95%CI 0.17 to 0.72, P=0.005). In addition, in comparison with Hook-wire localization, the microcoil localization could reduce the dislocation rate (OR=4.33, 95%CI 2.07 to 9.08, P<0.001), the incidence of pneumothorax (OR=1.62, 95%CI 1.12 to 2.33, P=0.010) and pulmonary hemorrhage (OR=1.64, 95%CI 1.07 to 2.51, P=0.020). Conclusion Although Hook-wire localization is slightly better than microcoil localization in the aspect of the success rate of pulmonary nodule localization, microcoil localization has an obvious advantage compared with Hook-wire localization in terms of controlling the incidence of dislocation, pneumothorax and pulmonary hemorrhage. Therefore, from a comprehensive perspective, this study believes that CT-guided microcoil localization is a preoperative localization method worthy of further promotion.
ABSTRACT
@#Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.
ABSTRACT
@#Objective To explore the application of Toumai® minimally invasive endoscopic robot in thoracic surgery, and to observe its safety and short-term surgical efficacy. Methods Three patients were enrolled from October to December 2021, including 1 male (69 years) and 2 females (47 years and 22 years). All 3 patients received surgery with Toumai® endoscopic surgical robot, including radical lung cancer surgery in 2 patients and mediastinal tumor resection in 1 patient. Results All 3 patients were successfully operated without conversion to thoracotomy, complication or death. For the male lobectomy patient, the total operation time was 120 min, the intraoperative blood loss was 100 mL, the catheter drainage time was 4 days and the hospital stay time was 5 days. For the female lobectomy patient, the total operation time was 103 min, the intraoperative blood loss was 100 mL, the catheter drainage time was 4 days and the hospital stay time was 5 days. For the female mediastinal tumor patient, the total operation time was 81 min, the intraoperative blood loss was 50 mL, the catheter drainage time was 3 days and the hospital stay time was 3 days. Conclusion The Toumai® minimally invasive endoscopic surgical robot is safe and effective in thoracic surgery. Compared with Da Vinci surgical robot, Toumai® has the same 3D visual field experience and smooth operation.

ABSTRACT
Objective:To evaluate the clinical efficacy and prognosis of robotic-assisted thoracoscopic surgery (RATS )compared with traditional thoracoscopic surgery (VATS) in the treatment of thymoma.Methods:The clinical data of 128 patients with thymoma who underwent surgery in our hospital from January 2006 to November 2019 were retrospectively analyzed, There were 83 males and 45 females. The age ranged from 23 to 76 years old, with an average of (45.89±13.84) years old. The patients were divided into RATS group (58 cases) and VATS group (70 cases). Cox proportional risk model was used to analyze the factors affecting the postoperative hospital stay. Results:Compared with VATS group, RATS group patients had longer operation time[(128.61±32.13)min vs. (96.42±45.37)min, P=0.036], less intraoperative blood loss[(35.25±5.62)ml vs. (58.36±3.65)ml, P=0.016], less blood transfusion (1.72% vs. 7.14%, P=0.029), and less postoperative complications (17.2% vs. 22.9%, P=0.039). The average total hospitalization cost was higher [(56 721.18±98 457.24) yuan vs. (25 135.68±12 403.29) yuan, P<0.001], and the average postoperative hospitalization time was shorter[(4.15±1.51) days vs. (6.65±2.74)days, P<0.001], all with statistically significant differences. However, there was no statistical differences in conversion to thoracotomy, intraoperative complication, the surgical margin was positive, postoperative infectionpostoperative drainage amount, postoperative drainage time, expenses for medicine and anesthetic fee( P>0.05). Multiple linear regression models showed that different groups ( P=0.013), age ( P=0.025), combined with myasthenia gr avis( P=0.047), combined with underlying disease( P=0.016), intraoperative blood loss( P=0.034), conversion to thoracotomy ( P=0.024), postoperative infection( P=0.008), postoperative complications( P=0.026) and postoperative drainage time ( P=0.031) affected postoperative hospital stay. Conclusion:Robot-assisted thymectomy is a safe and effective method for the treatment of thymomas. RATS recover faster after surgery with fewer complications and shorter hospital stays than RATS after thoracoscopic surgery, but more large, high-quality studies are needed to evaluate the effectiveness of RATS.
ABSTRACT
Objective:To investigate the safety and feasibility of endoscopic cholecystolithotomy after endoscopic ultrasonography (EUS)-guided lumen-apposing metal stent (LAMS) implantation in animals.Methods:Six miniature pigs of 30-35 kg were selected to laparotomy under intravenous anesthesia. Two to four sterile human stones with diameter of 0.8-2.0 cm were implanted in their gallbladder. After successful modeling, LAMS was implanted between the stomach and gallbladder under the guidance of EUS. Ultrafine endoscope was used to search and remove stones after passing the gastric stent into the gallbladder. Endoscopic sphincterotomy (EST) and endoscopic retrograde biliary drainage (ERBD) was performed to prevent bile leakage. And then ordinary endoscope was used to remove LAMS and close the wound. The success rate, operation time, and incidence of complications were analyzed.Results:Five pigs were successfully implanted with LAMS, and the ultrafine endoscope entered the gallbladder smoothly. Small stones were removed from the stone basket, and large stones were completely removed after laser lithotripsy. The total operation time was 87-128 min. No postoperative complications such as bleeding, perforation, infection, or biliary fistula were observed. Failure in 1 pig was due to the first EST plus ERBD, resulting in rapid reduction of gallbladder volume and away from the gastric cavity leading to puncture difficulties.Conclusion:Endoscopic cholecystolithotomy after EUS-guided LAMS implantation is safe and feasible, and may provide animal experimental evidence for potential therapeutic approach for patients with difficulty in cholecystectomy.
ABSTRACT
@#Objective To systematically evaluate the efficacy of tubular stomach and whole stomach reconstruction in the treatment of esophageal cancer. Methods We searched PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases to collect the randomized controlled trial (RCT) studies on the efficacy comparison between tubular stomach and total gastric reconstruction of esophagus in esophagectomy from their date of inception to May 2019. Then meta-analysis was performed by using RevMan 5.3 software. Results A total of Twenty-nine RCTs were included, and 3 012 patients were involved. The results of meta-analysis showed that the postoperative complications such as anastomotic fistula [RR=0.64, 95%CI (0.50, 0.83), P=0.000 6], anastomotic stenosis [RR=0.65, 95%CI (0.50, 0.86), P=0.002], thoracic gastric syndrome [RR=0.19, 95%CI (0.13, 0.27), P<0.001], reflux esophagitis [RR=0.23, 95%CI (0.19, 0.30), P<0.001], gastric emptying disorder [RR=0.39, 95%CI (0.27, 0.57), P<0.001] and pulmonary infection [RR=0.44, 95%CI (0.31, 0.62), P<0.001] were significantly reduced, and the postoperative quality of life score and satisfaction were higher at 6 months and 1 year in the tubular stomach group (P<0.05). In terms of intraoperative blood loss and postoperative hospital stay, they were better in the tubular stomach group than those in the whole stomach group (P<0.05). However, there was no statistically significant difference between the two groups in operation time, postoperative gastrointestinal decompression time, postoperative closed drainage time, postoperative 1-year, 2-year and 3-year survival rate, postoperative quality of life score at 3 weeks and 3 months, and postoperative life satisfaction at 3 weeks. Conclusion The tubular stomach is more advantageous than the whole stomach in the reconstruction of esophagus after esophagectomy.

Methods A retrospective analysis was performed on 10 patients with centrally located lung cancer undergoing robot-assisted sleeve lobectomy from March to December 2019 in our center, including 9 males and 1 female, aged 45-67 (55.0±8.9) years. Preoperative imaging and bronchoscopy showed central non-small cell lung cancer, involving the right upper lung in 3 patients, right lower lung in 2 patients, the left upper lung in 4 patients, and left lower lung in 1 patient. The operation time, Docking time, intraoperative blood loss volume, bronchial anastomosis time, number of dissected lymph nodes, drainage volume and postoperative hospital stay were analyzed. Results The da Vinci robot-assisted bronchial sleeve lobectomy was completed smoothly on 10 patients. The operation time was 135-183 (157.8±14.3) min, Docking time 6-15 (10.0±2.9) min, intraoperative blood loss volume 55-250 (124.5±61.8) mL, bronchial anastomosis time 17-40 (27.7±7.3) min, the number of dissected lymph nodes 16-23 (19.7±2.8), the drainage volume 200-600 (348.0±148.4) mL and postoperative hospital stay 7-11 (8.7±1.6) d. All patients had no bronchopleural fistula, pulmonary infection or atelectasis, and there was no perioperative death. Postoperative pathological findings were all squamous cell carcinoma. Conclusion Da Vinci robot-assisted sleeve lobectomy is safe and effective.
