Filter by:Many researches shows that Ba Duan Jin has clinical efficacy on cancer rehabilitation, respiratory diseases, psychological health, quality of life and so on. Studies examining the effects of Ba Duan Jin on patients with pulmonary nodules are sparse. Therefore, the aims of the present study are: 1) to examine the effects of Ba Duan Jin on physical and psychological condition, and 2) to examine the effects of Ba Duan Jin on quality of life.
In the past few years, circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), microRNAs, autoantibodies, and T-cell receptor repertoire are new biomarkers of liquid biopsy in cancer, which has been demonstrated to have a great value in diagnostics, treatment evaluation, and prognosis prediction. However, most of previous data were based on late stage tumor patients. This study plans to utilize the minimally invasive method to detect the changes of numbers of CTCs, ctDNA hot spot mutations and methylation signals, microRNAs, autoantibodies, and T-cell receptor repertoire in early stage lung cancer patients before and after pulmonary nodule biopsy, during therapeutic and follow-up periods, in order to evaluate the clinical values of above tumor-related biomarkers.
This is a multi-center, non-randomized, single-arm, prospective trial to evaluate a staged sampling methodology designed to maximize the diagnostic yield of lung biopsy in a single procedure setting.
The purpose of this study was to compare the safety and efficacy of CT-guided needle guidance using stereotaxic unit, navigation versus conventional biopsy technique for the patients scheduled to undergo percutaneous pulmonary nodule biopsy.
Analyse immune repertoire and genetic mutations of benign and malignant pulmonary nodule，and evaluate peripheral blood detection for identifying nature of pulmonary nodule.
Lung cancer screening programs are still discussed in Europe today, and one of the concern is radiation due to iterative CT. The aim of this monocentric, prospective, non randomized study is to compare an ultra low dose chest CT (approaching a two views X ray) versus a standard low dose chest CT for ≥4mm lung nodules detection, and secondary for lung nodule characterization and smoking associated findings (emphysema, bronchial abnormalities and coronary calcifications).
One of the main challenges of thoracic oncology lies in earlier diagnosis of lung cancer to improve survival rate, wich is about 15% at 5 years. This poor prognosis is often linked to late diagnosis. Efforts are being made worldwide to offer testing in patients at risk or earlier diagnosis of lung cancer in order to offer the patient curative treatments. Indeed, supported at the stage of nodule (less than 3 cm lesion), lung cancer is curable by surgery in 80% of patients. Nevertheless, there are many differential diagnoses and access to these lesions is often difficult and risky. In this context, the management of pulmonary nodules, which can be either benign lesions or beginners cancers, is a real challenge for pulmonologists and thoracic oncologists every day: it is important not to disregard a potentially operable nodule and avoiding offer patients invasive procedures for benign nodules. Indeed, many procedures (endoscopy, puncture under scanner, thoracotomy) are made to determine if suspicious nodules are benign or not. In the large National Lung Screening Trial, 28% of the procedures were associated with complications (including 11% classified severe and 16 deaths). It is therefore essential to develop non-invasive tools to refine treatment decisions.
Current state-of-the-art lung cancer early screening utilizes low-dose CT scan to identify lung nodules smaller than 3 cm in diameter. However, it's still a clinical challenge to differentiate between malignant and benign nodules. In previous studies, the investigators had taken the approach of methylation profiling by high throughput bisulfite DNA sequencing in tissue samples to identify specific methylation signatures. The investigators had learned methylation patterns that differentiate malignant vs. benign lesions from tissue samples by in-depth data mining, and then used pattern matching to classify plasma samples. In this study, the investigators are going to validate the efficacy of ctDNA methylation test for diagnosing early lung cancer by comparing results of the pre-surgery ctDNA methylation test with the post-surgery pathology.
We will perform an ultra low-dose CT (ULDCT) in addition to a regular chest CT scan for adult patients undergoing a clinically indicated chest CT. Using a recently developed computationally efficient algorithm for the denoising of ULDCT scans after image reconstruction, we will compare the sensitivity, specificity and accuracy of lesion detection with the ULDCT as compared to the regular CT scan.
This is a clinical trial to evaluate the intravenous administration of indocyanine green (ICG) as a method of intra-thoracic lesion localization. The primary purpose is to determine if intravenous ICG allows us to identify intra-thoracic lesions.
