AIM To update our experiences with minimally invasive McKeown esophagectomy for esophageal cancer. METHODS We retrospectively reviewed the medical records of 445 consecutive patients who underwent minimally invasive McKeown esophagectomy between January 2009 and July 2015 at the Cancer Hospital of Chinese Academy of Medical Sciences and used 103 patients who underwent open McKeown esophagectomy in the same period as controls. Among 375 patients who underwent total minimally invasive McKeown esophagectomy, 180 in the early period were chosen for the study of learning curve of total minimally invasive McKeown esophagectomy. These 180 minimally invasive McKeown esophagectomies performed by five surgeons were divided into three groups according to time sequence as group 1 (n = 60), group 2 (n = 60) and group 3 (n = 60). RESULTS Patients who underwent total minimally invasive McKeown esophagectomy had significantly less intraoperative blood loss than patients who underwent hybrid minimally invasive McKeown esophagectomy or open McKeown esophagectomy (100 mL vs 300 mL vs 200 mL, P = 0.001). However, there were no significant differences in operation time, number of harvested lymph nodes, or postoperative morbidity including incidence of pulmonary complication and anastomotic leak between total minimally invasive McKeown esophagectomy, hybrid minimally invasive McKeown esophagectomy and open McKeown esophagectomy groups. There were no significant differences in 5-year survival between these three groups (60.5% vs 47.9% vs 35.6%, P = 0.735). Patients in group 1 had significantly longer duration of operation than those in groups 2 and 3. There were no significant differences in intraoperative blood loss, number of harvested lymph nodes, or postoperative morbidity including incidence of pulmonary complication and anastomotic leak between groups 1, 2 and 3. CONCLUSION Total minimally invasive McKeown esophagectomy was associated with reduced intraoperative blood loss and comparable short term and long term survival compared with hybrid minimally invasive McKeown esophagectomy or open Mckeown esophagectomy. At least 12 cases are needed to master total minimally invasive McKeown esophagectomy in a high volume center.

BACKGROUND To summarize our experiences of single-port, two-port vs. three-port VATS pulmonary resection for lung cancer patients. METHODS Data of consecutive 1,553 patients who underwent video assisted thoracoscopic surgery (VATS) pulmonary resection for lung cancer in the Department of Thoracic Surgery of Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College between November 2014 and January 2016 were prospectively collected and analyzed. A propensity-matched analysis was used to compare the short-term outcomes of lung cancer patients who received VATS single-port, two-port and three-port pulmonary resection. RESULTS There were 716 males and 837 females. The mean age was 58.90 years (range, 25-82 years) and the conversion rate was 2.7% (42/1,553) in this cohort. After propensity score matching, there were 207 patients in single-port and two-port group, and 680 patients in three-port group. Propensity-matched analysis demonstrated that there were no significant differences in duration of operation (129 vs. 131 min, P=0.689), intra-operative blood loss (63 vs. 70 mL, P=0.175), number of dissected lymph nodes (12 vs. 13, P=0.074), total hospital expense (﹩9,928 vs. ﹩9,956, P=0.884) and cost of operation (﹩536 vs. ﹩535, P=0.879) between VATS single-port, two-port and conventional three-port pulmonary resection groups. There was no significant difference in the complication rate between two groups (5.3% vs. 4.7%, P=0.220). However, compared with three-port group, patients who underwent single port and two-port experienced shorter postoperative length of stay (6.24 vs. 5.61 d, P=0.033), shorter duration of chest tube (4.92 vs. 4.25 d, P=0.008), and decreased volume of drainage (926 vs. 791 d, P=0.003). CONCLUSIONS The short term outcomes between VATS single-port, two-port and conventional three-port groups for the surgical treatment of lung cancer were comparable. However, compared with three-port VATS pulmonary resection, single-port and two-port were associated with shorter postoperative length of stay, shorter duration of chest tube, and decreased volume of drainage.

BACKGROUND Preoperative neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have prognostic value in patients with various operable tumors. The aim of our study was to determine whether NLR and PLR are predictive of survival in thymic carcinoma patients after complete resection. METHODS A total of seventy-nine patients who underwent complete resection of thymic carcinoma at our hospital between January 2005 and December 2015 were retrospectively enrolled. Differential leukocyte counts were collected before surgery, and the relationships of NLR, PLR, and other patient clinical variables with survival were estimated by Cox regression analysis and Kaplan-Meier survival analysis. RESULTS Univariate analysis found that a high level of NLR was associated with lower disease-free survival (DFS) (HR: 3.385, 95% CI: 1.073-10.678, P=0.037) and lower overall survival (OS) (HR: 12.836, 95% CI: 1.615-101.990, P=0.016). The optimal NLR threshold of 4.1 could stratify the patients with high risk of recurrence or metastasis (P=0.026) and death (P=0.006). Meanwhile, the NLR value of >4.1 in those patients was associated with bigger tumor size (P=0.035) and more advanced Masaoka stages (P=0.040) compared with NLR ≤4.1. However, the PLR and other variables were not significantly associated with survival in thymic carcinoma patients. CONCLUSIONS The preoperative NLR of >4.1 was significantly associated with larger tumor size, more advanced Masaoka stages and reduced DFS and OS, but was not an independent predictor of survival in thymic carcinoma patients after complete resection.

BACKGROUND The aim of this study was to investigate the perioperative outcomes and 3-year overall survival (OS) of 2 approaches including Sweet and open Ivor Lewis esophagectomy in the surgical treatment of middle and lower third esophageal squamous cell carcinoma. METHODS The medical records of 1,746 consecutive patients who underwent esophagectomy for middle and lower esophageal cancer between January 2009 and September 2015 at the First Department of Thoracic Oncologic Surgery of Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively reviewed. The clinical variables and 3-year survival were compared between Sweet (n=1,701) and open Ivor Lewis (n=45) approaches in unmatched and propensity score matching analysis. RESULTS Patients who received esophagectomy by Sweet approach had shorter duration of surgery (mean 212 vs. 390 min; P<0.001), more lymph nodes removed (mean 24 vs. 19; P=0.005), lower overall complications rate (24.4% vs. 11.7%; P=0.009), lower total hospital cost (¥77,200 vs. 106,000; P=0.045) compared with patients who received open Ivor Lewis approach. After propensity score matching analysis, Sweet approach was still associated with decreased duration of surgery (mean 210 vs. 390 min; P<0.001), more lymph nodes removed (mean 24 vs. 19; P=0.050), and lower total hospital cost (¥86,800 vs. 106,000; P=0.045) compared with Ivor Lewis approach. However, there were no significant differences in overall complication rates (24.4% vs. 24.4%; P=1.000) between two approaches. There was no significant difference in 3-year OS between Sweet and open Ivor Lewis approaches (59.9% vs. 61.4%; P=0.637) in unmatched analysis and in matched analysis (77.8% vs. 61.4%; P=0.264). CONCLUSIONS In this cohort, for middle and lower third esophageal squamous cell carcinoma patients, both Sweet and open Ivor Lewis approaches are feasible in terms of perioperative outcomes and 3-year OS.

Background The pathologic stages of lymph nodes usually differ from preoperatively predicted in lung cancers and it is difficult to predict the metastasis of lymph nodes for the patients diagnosed as clinical stage IA non-small cell lung cancers (NSCLC). This study aimed to investigate the patterns of lymph node metastasis and the risk factors predicting lymph node metastasis in the patients with clinical stage IA NSCLCs. Methods All patients diagnosed as clinical stage IA NSCLC from July 2013 to June 2017 in our center were retrospectively reviewed, and a total number of 1,543 patients who underwent anatomical lobectomy with systematic lymph node dissection were enrolled in this study. Multivariate logistic regression analysis was performed to identify the risk factors predicting lymph node metastasis, and Fishers exact test was used to confirm the lymph node spread mode according to the locations of primary tumors. Results Totally, lymph node metastases presented in 131 patients (8.5%) in this series. Sixty-three patients presented N1 diseases, 17 patients showed only skipped N2 diseases, and 51 patients had simultaneous N1 and N2 positive lymph nodes. No lymph node metastasis was found in the patients with pure ground grass opacity (GGO). When patients were arbitrarily divided into six groups by the longest tumor diameter of ≤0.5, 0.6-1, 1.1-1.5, 1.6-2.0, 2.1-2.5, 2.6-3 cm, the lymph node metastasis rates of each group were 0% (0/20), 1.5% (4/264), 4.7% (20/429), 8.6% (29/336), 13.1% (38/290), 19.6% (40/204), respectively. When the patients with pure GGO were excluded, the lymph node metastasis rates in the patients with partial or total solid tumors were 0% (0/10), 2.4% (4/164), 6.6% (20/303), 11.7% (29/249), 16.0% (38/238) and 23.1% (40/173). The cut off value showed by receiver operating characteristic (ROC) curve for tumor size was 1.95 cm, and the area under the curve (AUC) was measured as 0.681 (P<0.001, 95% CI: 0.630-0.726). Multivariate logistic regression analysis indicated that male patients [odds ratio (OR) =3.34, P=0.012], smoking history (OR =14.12, P<0.001), solid components (OR =3.34, P=0.01), large tumor size (OR =1.9, P<0.001), poor differentiation (OR =2.25, P=0.013), lymphovascular invasion (OR =58.45, P<0.001), visceral pleural invasion (OR =48.37, P<0.001) were significantly associated with lymph node metastasis in clinical stage IA NSCLC. The rate of non-lobe specific lymph node metastasis was 15.8-40.0% when any of the lobe specific lymph nodes was positive, while it was only 0-2.2% when all lobe specific lymph nodes were negative. Conclusions Tumor size, solid components, poor differentiation, lymphovascular invasion, visceral pleural invasion and smoking history were significant factors predicting lymph node metastasis of clinical stage IA NSCLC. Patients with negative lobe-specific lymph node have very low risk of metastasis to the non-lobe specific lymph nodes. Lobe-specific lymph node dissection may become an alternative lymph node dissection mode for clinical stage IA NSCLC, especially for tumors ≤2 cm.

Background Patients with pathological stage I (p I) lung adenocarcinoma show variabilities in prognosis even after complete resection. The factors resulting in heterogeneities of prognosis remain controversy. The aim of this study was to identify the risk factors affecting recurrence/metastasis and survival in patients with curatively resected p I lung adenocarcinoma. Methods A total of 252 patients with p I lung adenocarcinoma underwent curative resection between January 1st, 2009 to September 30th, 2011 were retrospectively reviewed to analyze the associations of recurrence and survival with the following clinicopathological variables: gender, age, cigarette smoking, family cancer history, tumor size, TNM stage, tumor differentiation, visceral pleural invasion, bronchial involvement, lymphovascular invasion, postoperative adjuvant treatment, pathological subtypes and micropapillary pattern. Results Among those 252 patients, 48 had local recurrence or distant metastasis, the rest 204 patients had no relapse until the last follow-up. Cox univariate survival analysis revealed that tumor size (P<0.001), TNM stage [disease-free survival (DFS), P<0.001; overall survival (OS), P=0.004], tumor differentiation (P<0.001), bronchial involvement (P<0.001), lymphovascular invasion (DFS, P=0.021; OS, P=0.001) and micropapillary pattern (DFS, P<0.001; OS, P=0.003) were significantly associated with DFS and OS, while cigarette smoking (P=0.029) and pathological subtypes (P=0.041) were found to be risk factors for DFS either. In multivariate analysis, tumor differentiation (P<0.001) was an independent risk factor for both DFS and OS, TNM stage (P=0.007), bronchial involvement (P=0.004) and micropapillary pattern (P=0.001) only for DFS, while tumor size (P=0.009) and lymphovascular invasion (P=0.010) were found to be independent risk factors only for OS. Conclusions Tumor size, TNM stage, tumor differentiation, bronchial involvement, lymphovascular invasion and micropapillary pattern could be considered as risk factors for predicting local recurrence or distant metastasis and survival in curatively resected p I lung adenocarcinoma patients.

BACKGROUND It was reported in the literatures that the incidence of anastomotic leakage in patients with esophagogastric junction cancer decreased due to application of staplers and closure devices as well as gastric conduit technique in recent years, however, it increased slightly at our center since widely using the above devices and gastric conduit techniques from 2009. The objective of this study was to summarize our experiences in the management of anastomotic leakages and analyze the factors affecting leakage healing in the patients with esophagogastric junction cancer after surgical resection in recent 6 years. METHODS All patients who received surgical resections for esophagogastric junction cancer and diagnosed anastomotic leak at our center between January 2009 and December 2014 were retrospectively analyzed, we also enrolled the patients who had a longer hospital stay (>30 days) as they may develop anastomotic leak. The binary logistic regression in SPSS 16.0 was applied to analyze the factors that may affect leakage healing. RESULTS Of the 1,815 surgically treated esophagogastric junction cancer patients, 91 cases were diagnosed anastomotic leakage postoperatively. The patients were divided into two groups based on the median leakage healing time (40 days) in this series: fast healing group (37 cases) and slowly healing group (54 cases). All factors that may affect the leakage healing were put into analysis by using binary logistic regression. The results of the analysis showed that leakage size (OR =1.073, P=0.004), thoracic drainage (OR =12.937, P=0.037) and smoking index ≤400 (OR =1.001, P=0.04) significantly affected the healing time, while drinking history (P=0.177), duration of fever after anastomotic leak developed (P=0.084), and hypoproteinemia after leak (P=0.169) also apparently but not significantly affect the healing time. CONCLUSIONS Though many factors may affect leakage healing in the esophagogastric junction carcinoma patients, leakage size, thoracic drainage and smoking index (≤400) are the most important factors affecting the leakage healing. Placement of a chest tube beside the anastomosis area during operation for early identification and control of an anastomotic leak to minimize contamination of the mediastinum is the most important way to promote leakage healing. A chest tube placing into the purulent cavities after the patients experienced leaks is also important for the cure of leakage. More attention should be paid perioperatively to the patients who had a smoking index (≥400) and the patients who suffered fever or hypoproteinemia.
