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.
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.
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.
Intrathyroid thymic carcinoma (ITTC) is a rare type of malignent tumor. Two cases of ITTC were reported. Both patients underwent surgical treatment and recovered well after surgery, with no surgery-related complications and no recurrence during follow-up. In order to discuss the clinical features, diagnosis and treatment of ITTC, the literature review was conducted.
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.
The National Comprehensive Cancer Network (NCCN) released the latest version 1, 2022 of "NCCN guidelines for the clinical diagnosis and treatment of small cell lung cancer" (hereinafter referred to as "guideline"). Based on high-quality evidence-based medicine, this guideline provides references of clinical diagnosis and treatment for clinicians around the world. Compared with the version 3, 2021 of the "guideline", updates and revisions mainly focused on the progress of radiotherapy and systemic treatment. This article will interpret the updated therapy content in this new version of the "guideline".
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.
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.
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.
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.
