OBJECTIVETo summarize the mortality of esophagectomy in our series and compare the different mortalities based on 30-day deaths and 90-day deaths postoperatively.

METHODSA total of 954 patients undergoing esophagectomy by single-surgeon-team between January 2000 and December 2012 from our prospective database were enrolled. The mortalities based on 30-day and 90-day deaths postoperatively were compared, and the causes of deaths within 30 days and 90 days were analyzed.

RESULTSAmong all these 954 patients, a total of 20 postoperative deaths(2.1%) were observed: 11 within 30 days(1.1%) and 9 between 30 and 90 days after surgery(1.0%). The reasons for deaths within 30 days were as follows: 3 for respiratory failure related to anastomotic leakage,1 for bleeding after stenting due to anastomotic fistula, 1 for sepsis, 3 for respiratory failure from presenting preoperative respiratory morbidities, 2 for cardiac arrest caused by preoperative heart disorder, and 1 for multiple organ failure caused by early adjuvant chemotoxicity. The reasons for deaths between 30 and 90 days were as follows: 1 for respiratory failure related to anastomotic leakage, 1 for cardiac arrest from preoperative heart disorder, 1 for cerebrovascular accident, 1 for liver failure from liver cirrhosis presenting preoperatively, 1 for renal failure after operation, 1 for tumor progression and 2 for unknown reasons.

CONCLUSIONSince postoperative mortality calculated based on 30 days deaths postoperatively may underestimate the risk of esophagectomy, mortality calculated based on 90 days may be a better option.

OBJECTIVETo investigate the cause and the management of treatment and prevention of reoperation following esophagectomy.

METHODSClinical data of 946 cases with esophageal cancer undergoing esophagectomy from January 2000 to December 2012 by the same surgical team in the Beijing Cancer Hospital were retrospectively analyzed. Among them, 19 patients underwent reoperation after esophagectomy because of serious complications. Clinical features and treatment course of these 19 cases were summarized.

RESULTSThe indications and procedures of reoperation included thoracotomy for hemorrhage (n=4), diaphragmatic hernia repair (n=4), thoracic duct ligation for chylothorax (n= 4), re-suturing for incision dehiscence (n=4), re-laparotomy and re-thoracotomy for drainage of traumatic pancreatitis (n=1), re-laparotomy for intestinal obstruction (n=1), and tracheotomy for bilateral recurrent laryngeal nerve paralysis (n=1). All the 19 patients were successfully cured without perioperative deaths and further complications.

CONCLUSIONSThe indications of reoperation following esophagectomy include postoperative bleeding, diaphragmatic hernia, chylothorax and abdominal incision dehiscence.

Neoadjuvant therapy has become the first choice for locally advanced esophageal carcinoma. Patients with post-neoadjuvant positive lymph node staging (ypN+) have poor prognosis, and there is no effective adjuvant therapy. Programmed death protein-1 (PD-1) antibody can obtain better clinical efficacy in the treatment of advanced esophageal cancer. The authors designed a multicenter, prospective, randomized controlled clinical trial of Toripalimab (PD-1 antibody) adjuvant therapy on esophageal squamous cell carcinoma patients with ypN+ after the treatment of neoadjuvant chemotherapy combined with surgical resection, in order to provide clinical practices for the adjuvant treatment of ypN+ patients.

BACKGROUND: Virtual bronchoscopic navigation (VBN) assisted endobronchial ultrasonography with guide sheath (EBUS-GS) has reduced the difficulty and even avoiding radiation exposure during performing transbronchus lung biopsy (TBLB). To evaluate the feasibility and safety of virtual bronchoscopic navigation assisted endobronchial ultrasonography with guide sheath for peripheral pulmonary lesions. METHODS: We performed a retrospective analysis of the patients with PPLs who received VBN assisted EBUS-GS-TBLB in Peking University Cancer Hospital from January 2016 to December 2017. Their clinicopathologic data and complications were assessed. RESULTS: A total of 121 patients were enrolled in the study. The patients included 65 men and 56 women, with a mean age of (58.8±10.3) years. A total of 121 PPLs were examined, and 108 lesions of which could be detected by EBUS. The overall diagnostic yield of EBUS-GS was 73.5%. The diagnostic yield of malignancy was 82.5%. The combination of transbronchial lung biopsy, brush smear and bronchoalveolar lavage fluid provided the greatest diagnostic yield (χ²=6.084, P=0.014). Factors that significantly affected and predicted diagnostic success were EBUS probe within the lesions (χ²=20.372, P=0.000) and PPLs located in the central two-thirds of the lung (χ²=10.810, P=0.001). 1 patient (0.8%) suffered from intraoperative bleeding which could be managed under endoscopy. CONCLUSIONS VBN assisted EBUS-GS-TBLB for PPLs was an effective and safe procedure.

The increasing number of pulmonary nodules being detected by computed tomography scans significantly increase the workload of the radiologists for scan interpretation. Limitations of traditional methods for differential diagnosis of pulmonary nodules have been increasingly prominent. Artificial intelligence (AI) has the potential to increase the efficiency of discrimination and invasiveness classification for pulmonary nodules and lead to effective nodule management. Chinese Experts Consensus on Artificial Intelligence Assisted Management for Pulmonary Nodule (2022 Version) has been officially released recently. This article closely follows the context, significance, core implications, and the impact of future AI-assisted management on the diagnosis and treatment of pulmonary nodules. It is hoped that through our joint efforts, we can promote the standardization of management for pulmonary nodules and strive to improve the long-term survival and postoperative life quality of patients with lung cancer.

BACKGROUND: Currently, there is no consensus on the follow-up strategy (follow-up time interval and content) of non-small cell lung cancer (NSCLC) in the world, and the relevant clinical evidence is also very limited. In this study, we aimed to summarize the recurrence/metastasis sites and timings of stage I NSCLC patients based on their follow-up data, aiming to provide a basis of follow-up time interval and content for this group of patients. METHODS: We retrospectively analyzed the 416 stage I NSCLC patients that underwent continuous anatomic lobectomy between Jan. 2000 to Oct. 2013 in our prospective lung cancer database. According to the recurrence/metastasis sites and timings, the long term follow-up time interval and content were explored. RESULTS: The 5-yr disease free survival (DFS) and overall survival (OS) in the whole group were 82.4% and 85.4%, respectively. There were 76 cases (18.3%) had recurrence/metastasis during follow-up, among which the most frequent site was pulmonary metastasis (21 cases, 5.0%), followed by brain metastasis (20 cases, 4.8%), bone metastasis (12 cases, 2.9%), and mediastinal lymph node metastasis (12 cases, 2.9%). Among the factors that could influence recurrence/metastasis, patients with pT2a suffered from a higher recurrence/metastasis rate compared to patients with pT1 (P=0.006), with 5-yr DFS being 73.8% and 87.3%, respectively (P=0.002), and the 5-yr OS being 77.7% and 90.3%, respectively (P=0.011). CONCLUSIONS The commonest recurrence/metastasis sites of stage I NSCLC after anatomic lobectomy are lung, brain and mediastinal lymph nodes, the risk of recurrence/metastasis within 2 years were equal to that between 3 years and 5 years. The follow-up frequencies and content within 2 years could be adjusted according to T stages.

BACKGROUND: Thoracoscopic surgery has gradually become the major procedure for lung cancer surgery in our department. Its characteristics are minimal trauma and quick recovery, which make approximately 90% of patients discharge from the hospital after surgery. However, the postoperative complications still happen now and then. We analyzed the patients who had been hospitalized for longer than 7 days after thoracoscopic lung cancer surgery, aiming to summarize the types and risk factors of complications, and improve postoperative safety of patients. METHODS: The data were come from the prospective database of Thoracic Surgery Unit One in Peking Cancer Hospital, and patients that underwent thoracoscopic pulmonary surgery between Jan. 2010 and Dec. 2014 with length of stay more than 7 days were included in the study. The classifications of the complications were investigated and graded as mild or severe complications according to modified Claviengrading, the relationship between clinical factors and degrees of complications was also analyzed. RESULTS: The hospitalization of 115 cases were longer than 7 days after surgery, accounting for 10.3% (115/1,112) of the whole patients that underwent surgery during the same period. Eighty-one cases had mild complications, accounting for 7.3% (81/1,112) of the whole cases that underwent surgery during the same period and 70.4% (81/115) of the cases with prolonged length of stay; the proportions of severe complications in both groups were 3.1% (34/1,112) and 29.6% (34/115), respectively; and the proportions of complications that caused perioperative deaths were 0.18% (2/1112) and 1.7% (2/115), respectively. Among all the postoperative complications, the most common was air leakage for more than 5 days after surgery, with a total of 20 cases (1.8% and 17.4%). The other common complications were: atelectasis (19 cases, 1.7% and 16.5%), pulmonary infection (18 cases, 1.6% and 15.7%), etc. The less common complications was bronchopleural fistula (4 cases, 0.36% and 3.5%) with very high risk, and 2 cases died perioperatively due to the combination of acute respiratory distresssyndrome (ARDS). In the clinical factors, only preoperative low pulmonary function (FEV1%<70%) was the potential risk factor for postoperative severe complications (45.8% vs 23.6%, P=0.038). There was no significant difference either regarding the 5 year disease free survival or the 5 year overall survival between mild complication group and severe complication group, with 5 year DFS being 52.2% and 51.9%, respectively (P=0.894) , and 5 year overall survival being 64.0% and 53.5%, respectively (P=0.673). CONCLUSIONS Continuous postoperative air leakage, atelectasis and pulmonary infections were the major causes for prolonged hospitalization after thoracoscopic surgery for lung cancer, and bronchopleural fistula was the most perilous complications. Patients with low preoperative pulmonary function were more likely to have severe postoperative complication, however, this would not influence the long term survival of the patients.
