Trial Summary

What is the purpose of this trial?

This clinical trial compares the addition of needle-based confocal laser endomicroscopy (nCLE) and fluorescein to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS TBNA) with EBUS TBNA alone for the diagnosis of lung cancer in patients with peripheral pulmonary nodules. EBUS TBNA is a diagnostic procedure that can be used to sample lung tissue. nCLE is a novel high-resolution imaging technique that uses a laser light to create real-time microscopic images of tissues. It can be integrated into needles allowing real-time cancer detection during endoscopy. Fluorescein is an imaging agent that can be used to visualize tissue. Using nCLE and fluorescein in combination with EBUS TBNA may be more effective in diagnosing lung cancer than using EBUS TBNA alone.

Do I need to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking all current medications. However, you must not use beta-blockers within 24 hours before the procedure, and therapeutic anticoagulants must be held for an appropriate interval before the procedure. If you are undergoing chemotherapy, you cannot participate in the trial.

Will I have to stop taking my current medications?

The trial requires that you stop using beta-blockers 24 hours before the procedure and hold any therapeutic anticoagulants for an appropriate time before the procedure. If you are on these medications, you may need to stop them temporarily.

What data supports the idea that Confocal Laser Endomicroscopy for Lung Cancer is an effective treatment?

The available research shows that Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration (EBUS-TBNA), which is related to Confocal Laser Endomicroscopy, is a standard and important tool for diagnosing and staging lung cancer. It is considered safe and effective for examining lung tissues and has been used successfully with different needle sizes to obtain tumor samples. This suggests that similar techniques, like Confocal Laser Endomicroscopy, could also be effective in treating lung cancer.12345

What data supports the effectiveness of the treatment Needle-Based Confocal Laser Endomicroscopy with Fluorescein for lung cancer?

The research highlights that Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration (EBUS-TBNA) is a standard and effective procedure for diagnosing and staging lung cancer, which suggests that combining it with Needle-Based Confocal Laser Endomicroscopy could enhance its diagnostic capabilities.12345

Is endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) generally safe for humans?

EBUS-TBNA is generally considered safe, but there are rare reports of complications, including infections. Studies have focused on understanding these risks to improve patient safety.678910

What safety data is available for Confocal Laser Endomicroscopy in lung cancer treatment?

The safety data for Confocal Laser Endomicroscopy, particularly when used in conjunction with procedures like EBUS-TBNA, indicates that complications are rare. Several studies have focused on the incidence and risk factors of infectious complications associated with EBUS-TBNA, suggesting that while the procedure is generally safe, there are some risks involved. These studies highlight the importance of understanding potential complications, such as acute mediastinitis and other infectious issues, to ensure patient safety during and after the procedure.678910

Is the treatment EBUS-TBNA promising for lung cancer?

Yes, EBUS-TBNA is a promising treatment for lung cancer because it is a new, minimally invasive method that helps doctors diagnose and stage lung cancer effectively. It is safe, simple, and fast, with a good cost/benefit ratio compared to older methods.23111213

What makes the treatment EBUS-TBNA unique for lung cancer?

EBUS-TBNA (Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration) is unique because it is a minimally invasive procedure that allows doctors to obtain tissue samples for diagnosing and staging lung cancer, offering a safer and faster alternative with a better cost/benefit ratio compared to traditional methods.23111213

Findings from Research

Using a 19-G needle for EBUS-TBNA in 50 patients with suspected metastatic lung cancer resulted in a high success rate for testing molecular markers, with 90% success for PD-L1 and EGFR, and 86% for ALK, indicating its efficacy in obtaining sufficient tumor tissue.
The procedure was safe, with no adverse events reported, demonstrating that the larger needle size does not compromise patient safety while improving the quality and quantity of tissue samples for cancer diagnosis.
Pilot Study of the Performance of 19-G Needle in Endobronchial Ultrasound-guided Transbronchial Aspiration for the Diagnosis and Testing of Molecular Markers in Lung Cancer.Wahidi, MM., Davidson, K., Shofer, S., et al.[2023]
Endobronchial ultrasound-guided transbronchial aspiration (EBUS-TBNA) demonstrated high diagnostic accuracy in non-small cell lung cancer (NSCLC) patients, with an overall sensitivity of 92.3% and specificity of 100% across 164 patients studied from 2007 to 2009.
The use of EBUS-TBNA not only effectively diagnosed and staged NSCLC but also allowed 54.7% of patients with confirmed malignancy to avoid unnecessary surgery, highlighting its role as a less invasive initial diagnostic tool.
Roles of EBUS-TBNA in non-small cell lung cancer.Chung, FT., Kuo, CH., Chen, HC., et al.[2019]
Both computer EBUS-TBNA simulation and wet lab simulation are effective for teaching basic EBUS-TBNA skills, with no significant differences in procedure time or successful biopsy rates between the two methods.
However, the computer simulation group was better at correctly identifying lymph nodes, while wet lab simulation increased learner confidence in using the actual EBUS-TBNA bronchoscope, suggesting that both methods provide valuable but different learning benefits.
