Filter by:In this prospective analysis, investigators collected and evaluated data from patients who underwent TBB at the Respiratory Endoscopy Center of Sichuan Provincial People's Hospital. The procedures utilized a novel approach combining OCT with R-EBUS for guidance. Eligibility for participation was determined based on established guidelines for the application of diagnostic flexible bronchoscopy in adults. The admission criteria of this study were as followed: (1) voluntary participation and written informed consent signed, (2) age ≥ 18 years old, (3) the platelets count and PT, APTT tests were normal, (4) normal ECG, (5) found PPL's by chest computed tomography (CT) within 2 weeks and (6) could not detect the lesions through routine diagnostic bronchoscopy. The exclusion criteria of this study were as followed: (1) patients with contraindication of bronchoscopy (such as respiratory failure and acute cardio-cerebrovascular events), (2) patients who refuse biopsy because of physical reasons or personal wishes, (3) patients with the objective reasons (such as abundant blood supply around the lesion) who could not complete the biopsy, (4) patients who are participating in other clinical studies, (5) patients with poor compliance who are believed by the researchers to be unable to cooperate for the completion of the examination and follow-up, and (6) women who were pregnant. R-EBUS and OCT In this study, all procedures were conducted using a standardized flexible bronchoscopy (Olympus, Japan) featuring an outer diameter of 4.2mm. R-EBUS system (Olympus, Japan) incorporated an ultra-thin radial ultrasonic probe (Olympus UM-S20-17S), which measures merely 1.4mm in diameter. The OCT (Yongshida Medical Technology, Guangdong, China) probe is a cylindrical catheter, 1.7mm in diameter and 150cm in length. Placing the probe through the working channel of bronchoscope for real time dynamic scanning of lesions. Research Process In this study, the entirety of the procedures was performed by the same respiratory physician with 5 years of experience in respiratory endoscopic diagnosis and treatment, including preoperative evaluation, preparation, lesion localization and biopsy. The respiratory physician had examined the bilateral airways with flexible bronchoscopy after the completion of preoperative anesthesia and found no lesions. The subsequent step involved the precise placement of the OCT probe, guided by prior CT scan results. This stage was critical for marking the lesion, determining its nature (benign or malignant), and, in cases of malignancy, identifying its pathological classification. In instances where the OCT failed to identify any lesion, the R-EBUS was employed to facilitate lesion localization and biopsy. Conversely, when PPLs was detected via OCT, R-EBUS was additionally utilized to corroborate the PPLs localization and to assist in completing the biopsy procedure. For cases where OCT localization failed, R-EBUS would be used. After successful confirmation with R-EBUS, an attempt was made again to insert the OCT probe and completed biopsy. Rapid On-Site Evaluation (ROSE) was employed for the assessment of biopsy specimens. A total of five specimens were collected from each lesion and subjected to ROSE. In scenarios where ROSE provided a definitive diagnosis, no additional biopsies were deemed necessary. Conversely, in instances where ROSE yielded non-definitive results, further biopsy samples were obtained. All biopsy specimens were preserved in 10% formalin, preparing them for detailed histopathological analysis. The ultimate pathological diagnoses were determined based on the reports issued by the pathology department. In this study, the demographics of all patients were documented, including age, gender, and smoking history. Additionally, detailed clinical parameters, such as the location and size of the lesions, airway grades (ranging from 0 to 24) that the PPLs located, location time of OCT and the number of specimens, were systematically recorded. investigators also conducted extensive follow-up to track histopathological outcomes, whether from surgical biopsies, CT-guided percutaneous transthoracic needle biopsies, or other diagnostic avenues, including chest CT performed two months post-procedure. All the patients were followed up by telephone or outpatient service on the 1st and 3rd day after the procedure, and adverse events were recorded. All individuals underwent general anesthesia and were fitted with a laryngeal mask.
The ultrasound guided Thoracic paravertebral (TPV) block in the context of posterolateral thoracotomy offers targeted pain relief by anesthetizing the spinal nerves as they emerge from the intervertebral foramina, producing ipsilateral somatosensory, visceral and sympathetic nerve blockade. TPV block involves the injection of local anesthetic (LA) into the wedge-shaped paravertebral space deep to the superior costotransverse ligament (SCTL) Costach et al introduced the mid-point transverse process to pleura block (MTP) as a modification of conventional paravertebral block by placing the LA posterior to the (SCTL) under ultrasound guidence achieving an effective block without the necessity to approach the pleura and the attendant risks. In recent studies ,the ultrasound guided MTP block provided an effective analgesia in various surgical procedures including mastectomy , video-assisted thoracic surgeries and cardiac surgeries. In our study we hypothesized that the mid-point transverse process to pleura (MTP) block can provide an effective analgesia comparable with thoracic paravertebral (TPV) block in adult patients undergoing posterolateral thoracotomy incisions.
Single-center, randomized clinical trial (RCT) with low intervention level (Telenursing), for the monitoring of patients affected by lung cancer and melanoma who are candidates for first prescription with Targeted Therapies. The study population will consist of patients suffering from lung cancer and melanoma. The objective of the study will be to evaluate the effectiveness of a Telenursing intervention, comparing the mean score of the total SCNs scale (Supportive Care Needs) after one month of treatment in the treatment arm and in the control arm. Enrolled patients will then be randomized into two treatment arms: - Arm 1 (Control Group): current clinical practice - Arm 2 (Experimental group): Telenursing intervention.
Evaluation of safety and technical feasibility of the phenoWave MW Ablation System for microwave ablation of lesions in the lung.
This prospective observational study aims to investigate the relationship between cancer cachexia, stress levels, and metabolic changes in 150 lung cancer patients. Cancer cachexia, characterized by weight loss and muscle wasting, significantly impacts patient outcomes. Psychological stress is thought to contribute to cachexia development. Assessments will include medical history, physical examinations, laboratory tests, and imaging. Cancer cachexia will be diagnosed based on weight loss, reduced food intake, and inflammation markers. Psychological stress will be evaluated using questionnaires and biomarkers. Metabolic changes will be assessed using positron emission tomography-computed tomography (PET-CT) scans. The primary objective is to determine differences in metabolic activity between cachectic and non-cachectic patients. Secondary objectives include evaluating changes in brain activity and exploring the relationship between stress, inflammation, and metabolism.
This study plans to investigate the effectiveness of six-week light exposure combined with an exercise training program on improving sleep-wake rhythm, physical and mental symptoms, quality of life, one-year recurrence rate, and one-year survival rate of patients with lung and esophageal cancer.
This is an observational prospective bi-center study of 50 patients operated on advanced squamous cell carcinoma. The main aim is to investigate the efficacy of serum exosomal miRNA as a biomarker for predicting the therapeutic effect of immunotherapy combined with chemotherapy.
This clinical trial is looking at a combination of drugs called trastuzumab and pertuzumab. This combination of drugs is approved as standard of care treatment for adult patients with metastatic breast cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Trastuzumab and pertuzumab work in patients with these types of cancers which have a molecular alteration called HER2 amplification or HER2 activating mutation. Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also HER2 amplified or HER2 mutated. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
Robotic-assisted thoracoscopic surgery (RTS) segmentectomy is safe and effective for patients with early-stage non-small cell lung cancer (NSCLC). In RTS-segmentectomy, dissection and sealing procedures are performed by either staplers or energy devices. Staplers, the current standard of care, have been associated with higher operating costs compared to energy devices for open lobectomy, RTS lobectomy and minimally invasive segmentectomy. However, there is a lack of prospective research evaluating the costs of the two methods for lung dissection and vessel sealing in RTS-segmentectomy. This prospective trial seeks to determine whether it is feasible to conduct a randomized controlled trial evaluating the costs of the Signia stapler versus Vessel Sealer Extend energy device in RTS-segmentectomy for NSCLC. If this trial is feasible, we will be able to conduct a full-scale trial to compare costs and health outcomes, providing an economic evaluation that will inform hospital decision makers and clinicians in Canada.
ReSECT is a project promoted by the Spanish Society of Thoracic Surgery with the aim not only to become an indefinite, dynamic and inclusive registry, but also to establish a common structural framework for the development of future multicentre projects in the field of thoracic surgery in Spain. The goal of this nationwide prospective observational registry is: - To develop and validate forecasting tools based on powerful computational methods with the goal of assisting in decision-making and improving quality of care. - To evaluate the progressive implementation of certain surgical techniques that are on the rise, new technologies and future health programs. - To be aware of our results as specialty and professionals and to serve as a permanent benchmarking instrument in thoracic surgery. The first part of ReSECT, based on a personal registry design, will contemplate any thoracic surgical procedure performed by thoracic surgeons and residents in thoracic surgery in our country. Additionally, the Spanish thoracic surgery departments that voluntarily accept to collectively participate will contribute to specific surgical processes focused on certain procedures with specific objectives to be progressively implemented. The first and only surgical process implemented since the start of the ReSECT project will focus on patients to undergo anatomical lung resection with special interest in those cases whose reason for intervention was lung cancer. The main questions to answer in case of that first surgical process include: - What is the performance of current predictive models for perioperative and oncological outcomes in our country? - How could we modify previous predictive models to improve their performance? - What is the implementation of current guideline recommendations in our country and across institutions? - What is the potential impact of deviations from current recommendations? - What is my performance compared to the rest of the thoracic surgical departments in my country in terms of perioperative and oncological outcomes? ReSECT does not consider prespecified comparison groups of patients.
