In recent years, the computer science represented by artificial intelligence and high-throughput sequencing technology represented by omics play a significant role in the medical field. This paper reviews the research progress of the application of artificial intelligence combined with omics data analysis in the diagnosis and treatment of non-small cell lung cancer (NSCLC), aiming to provide ideas for the development of a more effective artificial intelligence algorithm, and improve the diagnosis rate and prognosis of patients with early NSCLC through a non-invasive way.
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.
China is a country with a high incidence of esophageal cancer. Most patients are already in the locally advanced stage when first diagnosed. Preoperative neoadjuvant therapy followed by surgery has become the standard treatment mode for them. Closely related to prognosis, the evaluation of tumor response is essential. Response evaluation criteria in solid tumors is the gold standard to evaluate tumor response, but the lesions must meet the measurement standards. Tumor regression grading (TRG) systems are designed to classify regressive changes after neoadjuvant treatment based on histopathological results to reveal prognostic information. Concentrating on pathologic assessment of esophageal cancer following neoadjuvant therapy, this article reviews histopathological changes, commonly used TRG systems and current debate.
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.
乳腺癌是女性中最常见的恶性肿瘤，在全球范围内其发病率有逐渐增高的趋势。自Halsted根治术创立近100多年以来，手术一直是治疗乳腺癌的主要方法之一，是病灶仍限于局部或淋巴结者的首选治疗方法。但由于对乳腺癌生物学特性研究的深入、早期诊断水平的提高、全身治疗的发展以及社会文化背景的改变，人们对乳腺癌有了更进一步的认识，乳腺外科治疗在近20年发生了巨大的变化。
Segmentectomy is the removal of certain segments of the lung with lesions and retaining the normal lung tissue of the lobe. Lung segmentectomy is considered difficult due to the lack of clear anatomical boundaries between lung segments. Segmentectomy has a variety of indications, such as lung cancer, metastatic lung tumors, and many non-malignant diseases. In the treatment of early stage lung cancer, segmentectomy was initially considered only as a treatment option for patients not suitable for conventional lobectomy. As more evidence emerged, the indications for segmentectomy have continued to change over time, and segmentectomy has been widely performed in patients with early stage lung cancer. Theoretically, segmentectomy leads to better preservation of lung function than lobectomy, but the risk of incomplete tumor resection is higher, so the indication of segmentectomy has become a focus of debate. This article will introduce the surgical techniques of segmentectomy and summarize the published and unpublished clinical studies on segmentectomy for the treatment of early stage lung cancer.
ObjectiveTo explore the training mode for improving the innovative scientific research ability of postgraduates of thoracic surgery.MethodsTwenty-two postgraduate students enrolled in the Department of Thoracic Surgery, Ruijin Hospital from September 2016 to June 2019 were targeted for training, and the teachers were 13 doctors in our department. Training methods included grant-based learning, formative learning and translational medical learning. In addition to the postgraduate education provided by the medical school, the training content also included more than 50 lectures about thoracic surgery, including surgical video explanation, perioperative management of thoracic surgery, interpretation of clinical guidelines, and intensive reading of the literature; it also included half-year clinical internship, 100 surgical operations and management of 5 medical beds in ward.ResultsClinical ability of the postgraduates were improved. Six postgraduate students enrolled in 2016 graduated successfully. They published 15 SCI papers and won more than 20 awards.ConclusionCultivating postgraduates of thoracic surgery oriented by innovative scientific research ability is conducive to the comprehensive understanding of thoracic diseases and the ability of innovative translation research.
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.
In recent years, immune checkpoint inhibitor therapy has changed the treatment of various malignant tumors. Immunotherapy for specific targets currently plays an important role in melanoma, lung cancer and other tumors. Malignant pleural mesothelioma (MPM) is an aggressive malignant tumor. Although the treatments include surgery, chemotherapy and radiotherapy, the clinical efficacy is limited, and the prognosis of advanced patients is poor. With the application of monoclonal antibodies such as programmed death 1/programmed death ligand 1 and cytotoxic T-lymphocyte antigen 4, MPM patients have more treatment options. And compared with traditional chemotherapy, immunotherapy may have the effect of improving survival and shrinking tumors. This article will summarize the current clinical trials of immunotherapy in MPM, and explain the current application and progress of immunotherapy in MPM from both single-agent immunotherapy and combined immunotherapy.
Surgery is the preferred treatment for early esophageal cancer. Minimally invasive esophagectomy (MIE) can significantly reduce the incidence of postoperative complications and mortality, but due to the complex esophageal anatomy, intraoperative esophageal exposure, separation, anastomosis and lymph node dissection are difficult. The da Vinci surgical system provides a 3D vision and a more flexible as well as stable robotic arm, which is very helpful in completing fine surgical procedures. Robot-assisted minimally invasive esophagectomy(RAMIE) has been carried out in a number of countries, including China. Robot-assisted Ivor-Lewis esophagectomy (RAILE) is a transthoracic approach of robots developed in recent years. This paper summarizes the current researches on RAILE.
