NCT07487883
Lung malignant tumors are a significant health threat with high incidence and mortality rates, and molecular imaging is crucial for early diagnosis, staging, prognosis evaluation, and therapeutic efficacy assessment. 18F-FDG PET imaging is widely used, but has limitations. CDH3 is a promising target for tumor-targeted imaging, as it is only expressed in cancerous epithelial cells. A new PET probe, 68Ga-TOI-1, targeting CDH3 has been developed with better affinity and selectivity than previous probes. Preclinical data support its safety and metabolic stability, and future research will explore its diagnostic and staging value in different types of lung tumors, providing a new and precise evaluation method for lung malignant tumors.

The significance is to accurately guide the perioperative analgesia of oxycodone in elderly patients, and to more effectively avoid toxicity and adverse reactions.
NCT07467005
During thoracic surgery, double-lumen endotracheal intubation with one-lung ventilation is routinely performed to optimize surgical exposure, facilitate operative manipulation, and prevent iatrogenic lung injury. In patients undergoing repeat pulmonary surgery, prior lung resection may lead to pleural adhesions and tracheobronchial distortion, which substantially increase the difficulty of bronchial intubation. Even with experienced operators, the malposition rate of conventional double-lumen tubes remains high. The video double-lumen tube enables continuous visualization of the trachea and carina during insertion, positioning, and one-lung ventilation, allowing real-time airway monitoring. However, no clinical studies have specifically investigated airway management in patients undergoing redo pulmonary surgery. This study aimed to evaluate the efficacy and safety of the video double-lumen tube during anesthesia in patients undergoing secondary pulmonary resection.
NCT07063290
Hypoxia represents the prevailing adverse occurrence during the sedation of patients undergoing fiberoptic bronchoscopy with propofol. A recent innovation in this domain is the COMBO Endoscopy Oropharyngeal Airway-a multifaceted device that encompasses capnography monitoring, bite block , oxygenation support, and oropharyngeal airway management. This device has been purposefully designed to cater to the unique requirements of endoscopic procedures. The principal objective of our randomized study is to assess the efficacy and safety of the COMBO Endoscopy Oropharyngeal Airway reduce the incidence of hypoxia on patients undergoing fiberoptic bronchoscopy under propofol sedation.
NCT07057648
What is this study about? This study tests a new robotic technology to take tissue samples from lung nodules (small spots in the lungs). Some lung nodules are cancer, but doctors need a tissue sample to know for sure. What is the problem? Current methods to get tissue from lung nodules only work about 7 out of 10 times. When they don't work, doctors may need riskier procedures. What is the new technology? The new technology is called robotic bronchoscopy (ssRAB). It uses a robot with special sensors to guide a thin tube more accurately to lung nodules than current methods. Who can join? Adults aged 19 or older who have lung nodules that need tissue sampling and are healthy enough for the procedure. What happens? Participants will have the robotic procedure while asleep under anesthesia. The robot guides a thin tube to the lung nodule to take a small tissue sample. Participants are watched for problems and followed for 6 months. What are the risks and benefits? The new technology may be more accurate and safer than current methods. The main risks are small chance of lung collapse or bleeding, similar to regular procedures. Why is this important? This study will show if the new robotic technology works well and is safe in Korea. If successful, it could help diagnose lung cancer earlier and more accurately. This study will include 100 people at Ulsan University Hospital in Korea.

NCT07322796
Nicotine is the most common preventable cause of death and is responsible for over seven million deaths worldwide. If current trends continue, tobacco will kill more than eight million people worldwide every year by 2030. Smoking tobacco products is the most important risk factor for the development of lung cancer. Passive smoking is also a major cause of lung cancer. Since July 2024, smokers and former smokers have been able to receive a low-radiation CT scan under certain conditions to detect lung cancer at an early stage. It is therefore to be expected that the number of diagnoses of pulmonary lesions or nodules will increase in the near future. The risk of developing and dying from tobacco-related diseases is reduced once nicotine cessation begins. Screening all patients for tobacco use, e-cigarette use, and providing behavioral counseling and pharmacotherapy to quit smoking are among the most valuable preventive services we can offer in healthcare. Nicotine dependence can be estimated using the so-called Fagerström test. An additional evaluation of nicotine behavior can be carried out by testing cotinine in urine, a method that is used, for example, in the listing for lung transplantation. Cotinine is a degradation product of nicotine that can be detected in the urine of smokers and passive smokers. Cotinine levels in urine depend on the frequency and quantity of nicotine consumption. The half-life of cotinine is 16 to 22 hours, which means that half of the cotinine is excreted from the body after this time. Another marker that can be used as a measure of tobacco consumption is carboxyhaemoglobin (COHb). This is hemoglobin with carbon monoxide at the binding site for oxygen. The reference range for carboxyhaemoglobin is 0.4 - 1.6 %. In smokers, values of 3-10 % are still considered normal. In our department, the smoking status of patients is assessed upon first contact. Support options for smoking cessation are offered and, upon request, initiated. Previous studies have shown that smoking is a risk factor for complications after thoracic surgical procedures and that patients who underwent thoracic surgery quit smoking almost twice as often compared to patients who did not undergo surgery. However, to the best of our knowledge, there is currently no study regarding smoking cessation before intervention in patients with nodules needing clarification (bronchoscopy or CT-guided puncture). Therefore, the aim of the study is to support and monitor smoking cessation before intervention in patients with nodules needing further diagnosis (bronchoscopy or CT-guided puncture).
NCT07360145
Lung cancer is one of the most common cancers and has one of the worst prognoses, mainly due to the difficulty of early diagnosis. In Italy, there are an estimated 41,000 new cases each year, and in 2021, the disease was responsible for approximately 34,000 deaths. The social impact is significant, as the disease is often diagnosed at an advanced stage, when the chances of survival are reduced: the 5-year survival rate is around 18% in advanced stages, while it can reach 90% if diagnosed at an early stage. Early-stage lung cancer mainly manifests itself in the form of pulmonary nodules, which can be detected by computed tomography (CT). However, the diagnosis of these nodules often requires invasive procedures, such as bronchoscopy, CT-guided needle biopsy, or surgical biopsies, which affect patients' quality of life and healthcare costs. For this reason, the ability to accurately distinguish between benign and malignant nodules is a central theme in clinical research. In recent years, artificial intelligence, particularly deep learning techniques, has shown considerable potential in supporting CT screening. Results show that AI can achieve performance superior to that of individual radiologists and comparable to that of a multidisciplinary team, using histological reports as a diagnostic reference. This confirms the value of AI as a tool to support clinical decision-making. Considering the multimodal nature of clinical data (images, text reports, diagnostic tests), there is growing interest in models capable of integrating multiple sources of information. In this context, the research project aims to develop a system capable of automatically recognizing pulmonary nodules and generating natural language text descriptions of the findings.
NCT07302217
This study aims to evaluate the effects of a technology-assisted preoperative home-based exercise program, delivered through a LINE Official Account and LINE BOT, on postoperative hand-grip strength, muscle endurance, and psychological distress in patients undergoing thoracoscopic pulmonary nodule resection. The study adopts a single-group pretest post-test design and plans to recruit 60 eligible patients. The intervention consists of at least one week of home exercise training before surgery, incorporating aerobic, resistance, and breathing exercises. Education, guidance, and interactive feedback are provided through the LINE platform to support adherence and exercise performance. Outcomes will be assessed at three time points: baseline (T0), immediately before surgery (T1), and two weeks after surgery (T2).
NCT07185035

This is a single-center, prospective, single-arm clinical study conducted at Beijing Cancer Hospital to evaluate the effectiveness, safety, and learning curve of preoperative indocyanine green (ICG) dye marking mixed with iodinated contrast agent under Monarch Robotic Assisted Bronchoscopy (RAB) with Cone-Beam CT (CBCT) for small pulmonary nodules that are difficult to locate during video-assisted thoracic surgery (VATS) sublobectomy. Eligible patients will undergo RAB localization immediately followed by VATS in the same operative session. The primary endpoints include the success rate of localization, effective localization, and VATS sublobar resection. Secondary endpoints include navigation success rate, operation times, reaching depth, complication rates, and health economic outcomes. The learning curve will be analyzed using the cumulative sum (CUSUM) method. A total of 50 patients will be enrolled and followed up for 14 days postoperatively.
NCT06810843
Non-intubated Thoracoscopic surgery (NITS) is a newly emerging minimally invasive surgical technique in recent years . Compared with traditional intubation general anesthesia, it has the advantages of less trauma, faster recovery and fewer complications . This surgical method allows patients to perform under local anesthesia or regional block and moderate sedation, providing a physiologic ventilation method , reducing the intervention on the respiratory system and conducive to rapid postoperative recovery. The importance of sedative drugs in non-intubated thoracoscopic surgery Successful implementation of non-intubated thoracoscopic surgery requires sound regional block, airway management, and rational use of intravenous sedation and analgesics . In addition, sedative drugs need to have less respiratory and circulatory inhibition and fewer side effects. Propofol, as the most commonly used sedative drug, has a high incidence of adverse reactions such as injection pain and respiratory and circulatory inhibition. A large number of meta-analyses and systematic reviews have compared the sedative effects of remazolam and propofol, proving that Remazolam, as a new sedative, has advantages such as short half-life, rapid onset, rapid recovery, and light respiratory and circulatory inhibition.Compared with traditional benzodiazepines, Remazolam has a shorter half-life, which is conducive to rapid postoperative wakeup and reduces the risk of discomfort and cognitive dysfunction in patients. In addition, remazolam has little influence on the respiratory system and is relatively stable on the circulatory system ，which is an ideal sedation option for non-intubated thoracoscopic surgery that retains spontaneous respiration. Afentanil mainly acts on μ opioid receptors , and its analgesic intensity is about 15 times that of morphine, which has the advantages of rapid onset, short duration of action, rapid recovery, high safety, and few adverse reactions . Afentanil has a short half-life , mild respiratory depression, low incidence of cough, postoperative nausea and vomiting . Remazolam combined with afentanil is widely used in various surgeries or examinations that preserve spontaneous breathing, such as gastroenteroscopy, ERCP, hysteroscopy, short-term plastic surgery and fiberbronchoscopy, and has shown the advantage of light respiratory circulation inhibition . We speculate that remazolam combined with afentanil may have certain advantages in non-intubated thoracoscopic surgery that retains spontaneous breathing. At present, the application of remazolam combined with afentanil in non-intubated thoracoscopic surgery is still lacking. The purpose of this study was to observe the safety and effectiveness of remazolam combined with afentanil in non-intubated thoracoscopic surgery, and to provide a better choice of sedation drugs for non-intubated thoracoscopic surgery.
NCT07047573
Research objective: To explore the clinical application effect of multi-omics detection based on flow cytometry analysis, single-cell data and images combined with clinical features in differentiating the benign and malignant nature of pulmonary nodules and the early diagnosis of lung cancer
NCT05968898
This is a pragmatic clinical trial that will study the effect of a radiomics-based computer-aided diagnosis (CAD) tool on clinicians' management of pulmonary nodules (PNs) compared to usual care. Adults aged 35-89 years with 8-30mm PNs evaluated at Penn Medicine PN clinics will undergo 1:1 randomization to one of two groups, defined by the PN malignancy risk stratification strategy used by evaluating clinicians: 1) usual care or 2) usual care + use of a radiomics-based CAD tool.
NCT06889467
Background and aim: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the gold standard of lung cancer staging, yet up to 15% of procedures produce inadequate samples for definite diagnosis or staging. In such cases, more invasive surgical procedures are usually considered. Fluid collected during EBUS-TBNA is centrifuged to produce a pellet for cell block histopathological examination , while the supernatant is usually discarded. It has been demonstrated that this supernatant can provide material for next generation sequencing (NGS) mutation analysis using liquid biopsy (LB) technics when the procedure yielded positive results (tumor cells were demonstrated in the aspirate). We wish to assess whether LB NGS of the supernatant may provide data regarding lymph nodes involvement in non-small cell lung cancer (NSCLC) in cases with a negative EBUS-TBNA evaluation (no tumor cell identified in the aspirate). Methods: A prospective feasibility study which will recruit participants with high suspicion for thoracic lymph nodes involvement in NSCLC who will be subjected to EBUS-TBNA. The final study group will comprise of 10 subjects with a negative EBUS-TBNA evaluation (no tumor cell detected) who will require surgical resection of the thoracic lymph nodes. EBUS-TBNA collected fluid will be centrifuged and separated. Cellular pellets will undergo cytological and histopathological evaluation, including tissue NGS, as usual. Cell-free DNA will be extracted from the supernatant and will undergo separate LB NGS targeted to genes frequently mutated in NSCLC. We will assess the concordance between the positivity of supernatant NGS and surgical lymph nodes staging, and the concordance between supernatant NGS and blood NGS. Expected results: We expect high concordance between surgical lymph nodes staging and supernatant NGS, that is, genetic mutations would be identified by the supernatant NGS in subjects with lymph nodes involvement by tumor, and not in those without it. Importance to Medicine: NSCLC is the leading cause of cancer mortality. Improving the effectiveness of EBUS-TBNA may reduce the need for additional invasive procedures, increase accuracy and reduce turnaround time of specimens.
NCT06628102
The goal of this trial is to (a) identify people at high risk of lung cancer who would benefit from LDCT screening but are currently ineligible based on current lung cancer screening criteria (b) provide the framework to manage patients with Incidental Pulmonary Nodules (IPNs) with appropriate follow-up based on accurate interpretation of the Chest CT scan that is already available and (c) develop a simple, point-of-care, minimally invasive test, focusing on the breath and circulating blood proteins, to detect lung cancer, and develop a method to differentiate between cancerous and non-cancerous nodules using a single. Participants will be asked to answer a questionnaire regarding their age, race/ethnicity, smoking history, and residential history if they have ever been told they have chronic obstructive pulmonary disease (COPD), high blood pressure, education level, medications and height and weight. Participants will then be asked to give a breath sample via the breath collection device. All this information will be collected before the breath collection. After that, participants will give 1-2 tablespoons of blood. CT scans with IPN(s) will be reviewed and run through a computer detection software to identify nodules, followed up as per current clinical guidelines.
NCT04331587
To collect data on diagnostic yield of thin and ultrathin bronchoscopes with radial probe endobronchial ultrasound (radial EBUS) and transbronchial needle aspiration (TBNA) during routine standard of care bronchoscopy for peripheral pulmonary lesions.
NCT05445635
Since the beginning of lung screening program in the different countries around the world by chest CT scan, numerous lung nodules and masses of unknown etiology are diagnosed. Usually, the pathological diagnosis is obtained by bronchoscopy. However, peripheral bronchi cannot be seen after the fifth bronchial division as the diameter of the broncoscope is greated than the diameter of the bronchi. Therefore, the Iriscope was developed. It consists in a thin catheter with a mini-camera at its distal extremity. The aime of this study is to evaluate the diagnostic yield of bronchoscopy guided by Iriscope in the setting of peripheral lung nodules and masses supect of malignancy, to compare the Iriscope to endobronchial radial ultrasonography (which is a validated technique to guide bronchoscopy in the setting of peripheral lung nodules and masses) and to evaluate the added value on the diagnostic yield by combining these 2 techniques.
NCT04740047
Evaluate the clinical utility and early performance of the Cios 3D Mobile Spin in conjunction with the Ion Endoluminal System, to visualize and facilitate the sampling of pulmonary nodules between 1-3 cm via the airway.
NCT04890301
Pulmonary nodules are small in size and easy to move with breathing. CT guided puncture is highly dependent on the personal experience of physicians, that is, the accuracy, efficiency and incidence of complications of puncture vary greatly among physicians. Puncture template (PT) assisted CT guided needle biopsy of pulmonary nodules has good clinical feasibility, which is expected to make up for the deficiency of simple CT guided needle biopsy, and make the needle biopsy of pulmonary nodules more accurate and standardized. This study intends to carry out a randomized controlled study to further evaluate the safety and effectiveness of PT assisted CT guided needle biopsy of pulmonary nodules, and provide higher quality data reference for its clinical application. Patients were randomly divided into two groups: PT assisted CT guided or simple CT guided lung biopsy. The operation related information, complications and postoperative pathological results of the two groups were collected. Primary end point: puncture accuracy Secondary end point: success rate of first needle puncture; complication rate (such as pneumothorax, bleeding, etc.); operation time; CT scan times; pathologic findings.
