ABSTRACT
@#Objective To investigate the safety of thoracic surgery for high-altitude patients in local medical center. Methods We retrospectively collected 258 high-altitude patients who received thoracic surgery in West China Hospital, Sichuan University (plain medical center, 54 patients) and People's Hospital of Ganzi Tibetan Autonomous Prefecture (high-altitude medical center, 204 patients) from January 2013 to July 2019. There were 175 males and 83 females with an average age of 43.0±16.8 years. Perioperative indicators, postoperative complications and related risk factors of patients were analyzed. Results The rate of minimally invasive surgery in the high-altitude medical center was statistically lower than that in the plain medical center (11.8% vs. 55.6%, P<0.001). The surgical proportions of tuberculous empyema (41.2% vs. 1.9%, P<0.001) and pulmonary hydatid (15.2% vs. 0.0%, P=0.002) in the high-altitude medical center were statistically higher than those in the plain medical center. There was no statistical difference in perioperative mortality (0.5% vs. 1.9%, P=0.379) or complication rate within 30 days after operation (7.4% vs. 11.1%, P=0.402) between the high-altitude center and the plain medical center. Univariate and multivariate analyses showed that body mass index≥ 25 kg/m2 (OR=8.647, P<0.001) and esophageal rupture/perforation were independent risk factors for the occurrence of postoperative complications (OR=15.720, P<0.001). Conclusion Thoracic surgery in the high-altitude medical center is safe and feasible.
ABSTRACT
@#Objective To explore the association of pretreatment hyponatremia with clinicopathological and prognostic characteristics of non-small cell lung cancer (NSCLC) patients. Methods The PubMed, EMbase, Web of Science, VIP, CNKI and WanFang databases were searched from the inception to July 12, 2021 for relevant literatures. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS) score. The relative risk (RR) and hazard ratio (HR) with 95% confidence interval (CI) were combined to assess the relationship between pretreatment hyponatremia and clinicopathological and prognostic characteristics. The prognostic indicators included the overall survival (OS) and progression-free survival (PFS). All statistical analysis was conducted by the STATA 15.0 software. Results A total of 10 high-quality studies (NOS score≥6 points) involving 10 045 patients were enrolled and all participants were from Asian or European regions. The pooled results demonstrated that male [RR=1.18, 95%CI (1.02, 1.36), P=0.026], non-adenocarcinoma [RR=0.86, 95%CI (0.81, 0.91), P<0.001] and TNM Ⅲ-Ⅳ stage [RR=1.17, 95%CI (1.12, 1.21), P<0.001] patients were more likely to experience hyponatremia. Besides, pretreatment hyponatremia was significantly related to worse OS [HR=1.83, 95%CI (1.53, 2.19), P<0.001] and PFS [HR=1.54, 95%CI (1.02, 2.34), P=0.040]. Pretreatment hyponatremia was a risk factor for poor prognosis of NSCLC patients. Conclusion Male, non-adenocarcinoma and advance stage NSCLC patients are more likely to experience hyponatremia. Meanwhile, the pretreatment sodium level can be applied as one of the prognostic evaluation indicators in NSCLC and patients with hyponatremia are more likely to have poor survival. However, more researches are still needed to verify above findings.
ABSTRACT
@#Objective To explore the relationship between metformin use and the risk and prognosis of esophageal cancer in patients with diabetes. Methods The PubMed, Web of Science, EMbase, VIP, WanFang and CNKI databases were searched by computer to identify relevant studies from inception to August 21, 2021. Newcastle-Ottawa scale (NOS) was used to evaluate research quality. The STATA 12.0 software was used to conduct the statistical analysis. Results A total of 14 studies involving 5 605 218 participants were included finally. NOS of all researches were≥6 points. The pooled results indicated that metformin use could decrease the risk of esophageal cancer in diabetics (OR=0.84, 95%CI 0.71-1.00, P=0.045), and could also prolong the overall survival of diabetics with esophageal cancer (HR=0.89, 95%CI 0.80-0.99, P=0.025). Conclusion Metformin use can not only decrease the risk of esophageal cancer in patients with diabetes, but also improve the prognosis of diabetics with esophageal cancer significantly. However, more prospective high-quality studies are still needed to verify the conclusion.
ABSTRACT
@#Esophageal carcinoma is a malignant tumor with high morbidity and mortality worldwide, and surgery is the main treatment currently. With the development of patient-centered care, the effect of surgery should not be limited to the improvement of the incidence of postoperative complications, mortality and other indicators. It is also important to provide experience related to disease and surgery from the perspective of patients. Therefore, more and more attention is paid to patient-reported outcomes by scholars. This paper will provide an overview of the international widely used, reliable and effective scales and researches about patient-reported outcomes in esophageal carcinoma.
ABSTRACT
@#Objective To review and analyze the treatment of chylothorax after video-assisted thoracoscopic lung cancer surgery and to discuss the best clinical treatment methods and effects. Methods A total of 400 patients diagnosed with chylothorax at the Department of Thoracic Surgery, West China Hospital, Sichuan University from January 2012 to January 2020 were continuously collected. According to the inclusion and exclusion criteria, 37 patients were finally included. There were 20 males and 17 females with an average age of 55.55±10.49 years. Chylothorax was diagnosed primarily by triglyceride levels (above 110 mg/dL) or the Sudan triple stain test. Treatment included surgical and non-surgical treatment. The overall incidence, high risk factors and treatment methods of chylothorax after radical thoracoscopic surgery for lung cancer were analyzed. According to the treatment methods, the patients were divided into a surgical treatment group and a non-surgical treatment group. The average daily drainage volume and average hospital stay of the patients between the two groups were analyzed. Results Included patients accounted for 0.3% (37/12 515) of lung cancer thoracoscopic surgery in our hospital during the same period. The incidence of postoperative chylothorax in patients with right lung surgery (0.2%, 29/12 515) was higher than that of patients with left lung surgery (0.1%, 8/12 515). Of 37 patients with chylothorax after lung cancer surgery, 32 patients were in the non-surgical treatment group (86.5%, 32/37), and the rate was higher compared with the surgical treatment group (13.5%, 5/37, P=0.000). The average daily drainage in the surgical treatment group was 777 mL more than that in the non-surgical treatment group (95%CI 588.58 to 965.55, P<0.001). The total drainage volume of the surgical treatment group was more than that of the non-surgical treatment group (8 609.2卤4 680.3 mL vs. 4 911.2卤3 925.5 mL, P=0.055). The postoperative hospital stay and total hospital stay in the surgical treatment group were shorter than those in the non-surgical treatment group (P=0.162, P=0.118). The tube indwelling time (8.2卤2.7 d) was shorter than that of the non-surgical treatment group (12.3卤6.8 d, P=0.204). Conclusion 聽 聽The treatment of chylothorax after radical resection of VATS lung cancer is still mainly non-surgical treatment. Surgical treatment should be initiated as early as possible when the drainage volume is too large 72 hours after chylothorax surgery after radical resection of VATS lung cancer.
ABSTRACT
BACKGROUND@#Patients with pulmonary nodules are treated by minimally invasive surgery, and postoperative symptoms have become the main factors affecting patients' emotion and quality of life. This study aimed to analyze the changes of postoperative symptoms in lung cancer patients with pulmonary nodules.@*METHODS@#The clinical data of eighty-eight lung cancer patients admitted to the same medical group of Department of Thoracic Surgery, West China Hospital of Sichuan University from June 2021 to September 2021 were prospectively collected and analyzed. The types and severity of clinical symptoms before operation, on discharge day, 30-day and 90-day after operation were analyzed.@*RESULTS@#The incidence of postoperative symptoms in lung cancer patients was 79.5%, and most patients suffered from mild (54.3%) and moderate (32.9%) symptoms. The main postoperative symptoms of lung cancer patients were pain (55.7%) and cough (37.2%). The incidence of pain at discharge (55.7%) was significantly higher than that at 30-day (23.7%, P=0.01) and 90-day (12.0%, P=0.01) after discharge. The incidence of cough was significantly higher at 30-day (66.1%) and 90-day (66.0%) than that at discharge (37.2%) (P=0.01, P=0.04).@*CONCLUSIONS@#The main postoperative symptoms of lung cancer patients with pulmonary nodules are pain and cough. The incidence and severity of pain decreases with time, and the incidence of cough increases but the severity decreased gradually.

@#Objective To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER) database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm<T≤2 cm at a ratio of 1∶4 according to the propensity scores. Results The results of multivariable logistic regression showed that older age (HR=1.04, 95%CI 1.03-1.05, P<0.001), male (HR=1.60, 95%CI 1.37-1.88, P<0.001), squamous carcinoma (HR=1.65, 95%CI 1.40-1.95, P<0.001), lymph node removed (HR=0.97, 95%CI 0.96-0.99, P<0.001) were risk factors for recurrence after surgery. We found that segmentectomy and lobectomy could reach similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm. Analyses of 1 441 patients with PSSNLC after matching (WCLCD∶SEER=325∶1 116) indicated that the 5-year overall survival rate of the patients in WCLCD was better than that in SEER database ( 89.8% vs. 77.1%, P<0.001). Conclusion Older age, male, squamous carcinoma, and lymph node removed are the risk factors for recurrence of PSSNLC. Segmentectomy shows similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm N0M0. The patients in the WCLCD shows better survival compared with of the patients in the SEER database.
ABSTRACT
@#Objective To analyze the causes and potential risk factors of re-catheterization after failure of no urinary catheter in patients undergoing lung cancer surgery. Methods The clinical data of 1 618 patients without urinary catheter indwelling during the perioperative period of thoracic surgery in our hospital from 2013 to 2019 were retrospectively analyzed, including 791 males and 827 females, with a median age of 58 years, ranging from 27 to 85 years. And the risk factors for re-insertion after failure of urinary catheter were investgated. Results The rate of catheter re-insertion was 1.5% (24/1 618). Compared with patients without re-insertion, patients with re-insertion had longer operation time [120.0 (95.0, 130.0) min vs. 120.0 (115.0, 180.0) min, P=0.015] and more intraoperative fluid infusion [800.0 (600.0, 1 100.0) mL vs. 1 150.0 (725.0, 1 350.0) mL, P=0.008]. Further multivariate analysis found that the operation time (OR=1.014, P=0.004, 95%CI 1.005-1.024) and intraoperative fluid infusion (OR=1.001, P=0.022, 95%CI 1.001–1.002) were independent risk factors for re-insertion. Conclusion The rate of catheter re-insertion in lung cancer patients is relatively low, and conventional no placement of catheter is safe and feasible after lung cancer surgery. Increasing operation time or intraoperative infusion volume may increase the risk of catheter re-insertion after lung cancer surgery.
ABSTRACT
@#Objective To investigate the optimal treatment scheme for the first primary spontaneous pneumothorax (PSP) in young patients. Methods The clinical data of 171 patients with the first PSP were retrospectively analyzed who were treated in Huaihe Hospital of Henan University between November 2011 and October 2017. There were 157 males and 14 females with a median age of 18 years at onset and a median body mass index of 18.51 kg/m2. According to the treatment methods, they were classified into two groups, a conservative treatment group (a non-surgical group, n=86) and a surgical group (n=85). The characteristics including clinical data, efficacy evaluation criteria, complications and recurrence of the two groups were analyzed. Results As a result, 73.68% of the patients suffered PSP in their daily routine. The drainage duration in the non-surgical group was longer than that in the surgical group (4 d vs. 3 d, P=0.008). There was no statistical difference in the success rate of lung re-expansion between the two groups (98.85% vs. 100.00%, P=1.000). The proportion of the surgical group using postoperative analgesic drugs was higher than that in the non-surgical group (48.23% vs. 10.46%, P=0.000). The recurrence rate of the surgical group was lower than that of the non-surgical group (3.53% vs. 46.51%, P=0.000). No relationship between smoking and recurrence of pneumothorax was found in both groups (P=0.301, P=1.000). The success rate of lung re-expansion in the non-surgical group was not statistically different between the 24F subgroup and the 12F subgroup (39/39 vs. 33/34, P=0.458). No advantage of intraoperative pleural fixation was found in the surgical group (P=0.693). Conclusion Thoracoscopic surgery is the first choice for the treatment of the first PSP in young patients.
ABSTRACT
@#Objective To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.
ABSTRACT
Tumor microenvironment (TME) is a dynamic network distributed around tumor cells. Cancer-associated fibroblasts (CAFs), as an important component of the TME, are not only closely related to normal fibroblasts, but also can secrete a variety of substances to participate in the regulation of the TME. Exosomes, one of the substances from CAFs, can promote the formation and development of lung cancer, including promoting the formation of TME, increasing pulmonary tumor cell invasion and metastasis, mediating pulmonary tumor immunosuppression and participating in radiotherapy and chemotherapy resistance. This article reviews the current research status and progress of cancer associated fibroblasts-derived exosomes in lung cancer. .

To explore the operation process and clinical effect of day surgery in patients with lung cancer by fusing the concept of enhanced recovery after surgery (ERAS) and minimally invasive surgical techniques.@*METHODS@#A prospective study was planned with the approval of our institutional review board. 153 lung cancer patients who underwent anatomic resection in a single medical group between June 2019 and Nov 2019 were randomized. 20 patients were applied day surgery and 28 patients by inpatient surgery and the average length of stay, average hospital cost , complications and adverse reactions were analysed.@*RESULTS@#The average hospital day in DSG group (1 d) was significantly shorter than in ISG group (7.7±2.8) d (P=0.000). The average hospital cost in DSG group (38,297.3±3,408.7)¥ was significantly lower than in ISG group (47,831.1±7,376.1)¥ (P=0.000). There was no significant difference in the incidence of postoperative complications between the daytime surgery group (5.0%) and the inpatient surgery group (3.6%) (P=0.812). The postoperation adverse reactions in DSG (10.0%) and ISG (17.9%) is no difference (P=0.72).@*CONCLUSIONS@#Our study showed that the same clinical effect achieved between DSG and ISG, and recover quickly lung cancer patients after day surgery.
ABSTRACT
@#The severe situation of the spread of novel coronavirus pneumonia (COVID-19) poses a huge challenge to the admission and management of patients undergoing selective thoracic surgery. In order to ensure that patients can receive surgical treatment in time, and we can effectively prevent the outbreak and spread of the disease in the surgical department, the department should comb the relevant content from multiple aspects in accordance with the specific situation. It is necessary to adopt a new admission process of patients undergoing selective surgery and COVID-19 investigation process for patients and their families during the epidemics. We should improve the companion and suspected patient management system during the epidemic. Patients who are planning to undergo surgery need to be strictly checked for COVID-19 infection before surgery. The treatment and management strategies of patients undergoing thoracic surgery in our department are summarized in this paper.
ABSTRACT
@#Objective To explore the correlation of preoperative D-dimer (DD) level with prognosis in Chinese esophageal cancer patients. Methods PubMed, EMbase, Web of Science, Cochrane Library, CNKI, VIP, Wanfang, SinoMed databases were searched to identify potential studies which assessed prognostic value of preoperative DD level in Chinese esophageal cancer patients from the establishment date of each database to March 20, 2019. The Stata 12.0 software was applied to conduct the meta-analysis and the hazard ratio (HR) with 95% confidence interval (CI) was combined to evaluate the relation between preoperative DD level and survival of Chinese esophageal cancer patients. Results A total of 5 studies involving 1 277 patients were included. The quality score of each study was ≥6 points. The results showed that the elevated preoperative DD level was significantly associated with poor overall survival (OS, HR=1.49, 95%CI 1.05-2.10, P=0.025) and cancer-specific survival (CSS, HR=1.83, 95%CI 1.39-2.42, P<0.001). However, no significant relation of preoperative DD with disease-free survival (DFS) was observed (HR=1.55, 95%CI 0.89-2.70, P=0.125). Conclusion High preoperative DD level may be an independent prognostic factor for Chinese patients with esophageal cancer. More prospective studies with bigger sample sizes are still needed to verify our results.
ABSTRACT
The good results of enhanced recovery after surgery (ERAS) combined with minimally invasive surgery are reflected in reducing the incidence of perioperative complications and shortening the length of hospitalization (LOS). It has been widely used in surgical fields of different specialties. The implementation of the day surgery mode can shorten the waiting time for patients and reduce the financial burden. Especially in thoracic surgery, the shorter the waiting time in the hospital, the more beneficial for the patient's physical and psychological recovery. With the widespread implementation of minimally invasive technology and accelerated rehabilitation procedures, the application of ERAS in thoracic surgery has made it possible for some thoracic surgery to be completed in the day surgery. This article summarizes the current application of ERAS in the field of thoracic surgery and the development prospects of day surgery models in China.

ABSTRACT
@#The postoperative symptom burden in patients with lung cancer is severe and adversely impairs their quality of life. Symptom management is the cornerstone of medical care. Patient-reported outcome (PRO)-based symptom management is being increasingly recognized as the best "patient-centered care" model in clinical practice. However, the precise implementation of this model in patients undergoing lung cancer surgery is hindered by the lack of a lung cancer surgery-specific scale, implementation standards, clinical application parameters and high-quality researches. The use of a precise and simple PRO scale and an electronic PRO platform may greatly improve the feasibility of implementing this model. Currently, the application of PRO-based symptom management in lung cancer surgery is still being explored and needs to be improved in clinical research and practice.
ABSTRACT
The cell cycle-related transcription factor E2F1 is a member of the cell cycle-related transcription factor E2F family, mainly involved in various cell processes including cell cycle progression, DNA repair, DNA replication, cell differentiation, proliferation, and apoptosis. E2F1 is highly expressed in a variety of tumor tissues and cells, and it plays a role as a cancer-promoting gene. The up-regulation of E2F1 expression is closely related to the occurrence, development, metastasis and prognosis of tumors. Therefore, E2F1 is expected to become a new target for cancer treatment. This article reviews the latest research progress of E2F1 in current common tumors. .
