ObjectiveTo analyze the risk factors for complications after robotic segmentectomy.MethodsClinical data of 207 patients undergoing robot-assisted anatomical segmentectomy in our hospital from June 2015 to July 2019 were retrospectively analyzed, including 69 males and 138 females with a median age of 54.0 years. The relationship between clinicopathological factors and prolonged air leakage, pleural effusion, and pulmonary infection after surgery was analyzed.ResultsAfter robot-assisted segmentectomy, 20 (9.7%) patients developed prolonged air leakage (>5 d), 17 (8.2%) patients developed pleural effusion, and 4 (1.9%) patients developed pulmonary infection. Univariate logistic regression showed that body mass index (BMI, P=0.018), FEV1% (P=0.024), number of N1 lymph nodes resection (P=0.008) were related to prolonged air leakage after robot-assisted segmentectomy. Benign lesion was a risk factor for pleural effusion (P=0.013). The number of lymph node sampling stations was significantly related to the incidence of pulmonary infection (P=0.035). Multivariate logistic analysis showed that the BMI (OR=0.73, P=0.012) and N1 lymph node sampling (OR=1.38, P=0.001) had a negative and positive relationship with prolonged air leakage after robot-assisted segmentectomy, respectively.ConclusionThe incidence of pulmonary complications after robot-assisted segmentectomy is low. The lower BMI and more N1 lymph node sampling is, the greater probability of prolonged air leakage is. Benign lesions and more lymph node sampling stations are risk factors for pleural effusion and lung infection, respectively. Attention should be paid to the prevention and treatment of perioperative complications for patients with such risk factors.
Objective To evaluate the effects of robot-assisted Ivor Lewis esophagectomy (RAILE) in surgical treatment of esophageal cancer. Methods We retrospectively analyzed the clinical data of 70 patients diagnosed with mid-lower esophageal cancer undergoing RAILE in the Department of Thoracic Surgery in Ruijin Hospital Affiliated to Shanghai Jiaotong University between May 2015 and April 2018. There were 54 males and 16 females at average age of 62.0±7.6 years. Forty patients underwent circular end-to-end stapled intrathoracic anastomosis and 30 had a double-layered, completely hand-sewn intrathoracic anastomosis. Results The mean operating time was 308.7±60.6 minutes. And blood loss was 190.0±95.1 ml. There were 2 patients who underwent conversion to thoracotomy. There was no in-hospital and 30-day mortality. Overall complications were observed in 24 patients (34.3%), of whom 6 patients (8.6%) had anastomotic leakage. The median length of hospitalization was 9.0 (interquartile range, IQR, 5.0) days. The mean tumor size was 3.2±1.5 cm, and R0 resection was achieved in all patients. The mean number of totally dissected lymph nodes was 19.3±8.7. Conclusion RAILE is safe and technically feasible with satisfactory perioperative outcomes.
The National Comprehensive Cancer Network (NCCN) updates the "NCCN clinical practice guidelines in oncology: Lung cancer screening" annually, and the second edition of 2024 was released in October 2023. The 2024 edition of the guidelines builds on the 2023 edition with some updates on description and assessment of risk factors for lung cancer, evaluation and follow-up of lung nodules found during initial and subsequent screening, and low-dose CT screening protocols and imaging modalities. In this article, we will introduce the above updates and provide reference for lung cancer screening in China by combining the relevant guidelines and consensus in China.
Cuproptosis, recently defined as a unique form of cell death distinct from programmed cell death, is triggered by copper overload within mitochondria. Genes associated with cuproptosis have been found to correlate with tumorigenesis and tumor progression, making the targeting of cuproptosis pathways a promising direction for anti-tumor therapies. Copper ion carriers can transport copper ions into cells, inducing cuproptosis and laying the foundation for its application in cancer treatment. This article elaborates on the homeostasis of copper and the mechanisms related to cuproptosis, further clarifying the relationship between cuproptosis and lung cancer treatment targets. This review aims to summarize current progress in research related to cuproptosis and lung cancer, providing new theories and bases for the clinical treatment of lung cancer.
Recently, anatomical segmentectomy emerges as a hot spot in clinical research for surgical treatment of early-stage lung cancer. The techniques of segmentectomy are more elaborate and complicated than lobectomy, because of the considerable anatomic variations of segment blood vessels and bronchus. In a long term, video-assisted thoracic surgery is the mainly minimally invasive approach. As a new approach of minimally invasive surgery, da Vinci robot system possesses three-dimensional and high definition view, better dexterity mechanical wrist and tremor filtering system, which are the main advantages over video-assisted thoracic surgery. All the superiorities of robot system provide good supports for performing segmentectomy. Robot-assisted segmentectomy has been carried out in many medical centers in China and abroad until now. However, most surgery cases often lack adequate controls on quality.
The National Comprehensive Cancer Network (NCCN) has updated and released the latest content of the NCCN guidelines for the clinical diagnosis and treatment of non-small cell lung cancer (NSCLC) in the version 1, 2022. Based on high-quality clinical evidence and the latest research progress of the diagnosis and treatment of NSCLC, the guidelines have been widely recognized and welcomed by clinicians around the world. Compared with the version 7, 2021, the new version has been updated and revised in some parts of chapters and sections, mainly focusing on targeted therapies and molecular testing. This article will interpret the updated therapy content of the new version.
Based on new clinical evidence, the National Comprehensive Cancer Network (NCCN) annually updates and releases the "NCCN Guidelines for the Clinical Diagnosis and Treatment of Non-Small Cell Lung Cancer" which has become the reference for clinical diagnosis and treatment approved and complied by clinicians worldwide. On November 25, 2020, the latest 2021 V1 version of "NCCN Clinical Diagnosis and Treatment Guidelines for Non-Small Cell Lung Cancer" (hereinafter referred to as "Guidelines") was released. Compared with the 8th edition of the "Guidelines" in 2020, many updates focused on the progress of targeted and immunotherapy. This article will provide the interpretations of the updated therapy content of this edition of the guidelines.
Chinese Medical Association Guidelines for Clinical Diagnosis and Treatment of Lung Cancer (2023 Edition) has been released in July 2023. Based on the 2022 edition, the 2023 edition of the guideline has been updated in the aspects of lung cancer screening, pathology, surgical standards, neoadjuvant therapy, targeted therapy and treatment of advanced lung cancer. This article will give a brief introduction to these updated parts.
