NASHVILLE, Tenn. — Form-sensing robotic-assisted bronchoscopy with cone-beam CT imaging confirmed promise for diagnosing central, distal-airway and peripheral pulmonary lesions in a single-center examine introduced on the CHEST Annual Assembly.
“Form-sensing robotic-assisted bronchoscopy mixed with superior imaging methods comparable to cone-beam CT is a more moderen approach that enables us to diagnose and stage lung most cancers in a single process with excessive diagnostic accuracy and a very good security profile. It has potential to change into the usual of take care of diagnosing pulmonary lesions if we now have additional research confirming these findings,” Kim Styrvoky, MD, assistant professor of drugs at College of Texas Southwestern Medical Heart, instructed Healio.
Styrvoky and colleagues reported outcomes of a retrospective evaluation of the primary 200 biopsy procedures of 209 lung lesions evaluated utilizing shape-sensing robotic-assisted bronchoscopy (Ion, Intuitive) and cone-beam CT at UT Southwestern from December 2020 to February 2022.
“Usually, sufferers who current with suspicious lung lesions endure a nonsurgical biopsy previous to definitive therapy; this may be with interventional radiology with CT-guided biopsies or bronchoscopic biopsies. The aim with bronchoscopy is that if we’re capable of diagnose these lung nodules and carry out mediastinal staging in a single process that may doubtlessly enable sufferers to not have repeated procedures with dangers of additional problems or delaying their care,” Styrvoky instructed Healio. “The present bronchoscopic methods for doing biopsy of lung lesions is restricted. There have been latest advances within the area attempting to enhance that diagnostic yield.”
Form-sensing robotic-assisted bronchoscopy is a more moderen expertise that encompasses a maneuverable catheter that enables for extra exact navigation and with direct visualization whereas navigating the airways. It allows lively robotic management of the catheter throughout navigation and the biopsy course of, in line with Styrvoky. Mixed with real-time cone-beam CT imaging, this enables the doctor to substantiate if the catheter and lesion are in good positioning, she mentioned.
“These two applied sciences mixed are hopefully resulting in an improved diagnostic yield,” Styrvoky mentioned.
Outcomes of the primary 200 procedures to pattern 209 lesions in 198 sufferers had been as follows:
- lesions ranged from 7 mm to 73 mm and the imply largest lesion diameter was 22.6 mm;
- general prevalence of malignancy was 64.1%, the bulk being lung most cancers but in addition together with metastatic illness from different primaries;
- price of non-diagnostic sampling was 11% (23 of 209 samples);
- diagnostic accuracy was 91.4%;
- sensitivity was 87.3% and specificity was 98.7%; and
- detrimental predictive worth was 81.3% and constructive predictive worth was 99.2%.
Of observe, “we didn’t have a look at simply nodules; we biopsied strong lesions, floor glass lesions, infiltrates, mass-like opacities — something that actually wanted focused sampling we included on this examine, which has similarities to what individuals in actual follow would do, not limiting to a sure inhabitants,” Styrvoky mentioned.
The process yielded low danger for problems. Solely two sufferers had pneumothorax and there have been no main bleeding occasions, in line with the outcomes.
“Along with lung most cancers, this expertise additionally has the potential for use in nonmalignant processes,” Styrvoky mentioned. “Finally, I believe this expertise can be utilized as a protected method to get focused sampling within the lungs.”
The researchers plan to proceed to prospectively consider shape-sensing robotic-assisted bronchoscopy with cone-beam CT to judge outcomes, elements that enhance diagnostic accuracy, scale back radiation publicity and finally fine-tune the process to make it as environment friendly and protected for sufferers as attainable, in line with Styrvoky.
This examine is being introduced within the Novel aids within the prognosis of lung most cancers: Guidelines and robots session on Monday, Oct. 17, at 1:30 p.m.
