Quality control and primo-diagnosis of transurethral bladder resections with full-field OCT

Montagne P, Ducesne I, Anract J, et al. Quality control and primo-diagnosis of transurethral bladder resections with full-field OCT. Proc. SPIE 10038 – 1003805 (2017). doi:10.1117/12.2250313.

Abstract

Transurethral resections are commonly used for bladder cancer diagnosis, treatment and follow-up. Cancer staging relies largely on the analysis of muscle in the resections; however, muscle presence is uncertain at the time of the resection. An extemporaneous quality control tool would be of great use to certify the presence of muscle in the resection, and potentially formulate a primo-diagnosis, in order to ensure optimum patient care. Full-field optical coherence tomography (FFOCT) offers a fast and non-destructive method of obtaining images of biological tissues at ultrahigh resolution (1μm in all 3 directions), approaching traditional histological sections. This study aimed to evaluate the potential of FFOCT for the quality control and the primo-diagnosis of transurethral bladder resections. Over 70 transurethral bladder resections were imaged with FFOCT within minutes, shortly after excision, and before histological preparation. Side-by-side comparison with histology allowed to establish reading criteria for the presence of muscle and cancer in particular. Images of 24 specimens were read blindly by three non-pathologists readers: two resident urologists and a junior bio-medical engineer, who were asked to notify the presence of muscle and tumor. Results showed that after appropriate training, 96% accuracy could be obtained on both tumour and muscle detection. FFOCT is a fast and nondestructive imaging technique that provides analysis results concordant with histology. Its implementation as a quality control and primo-diagnosis tool for transurethral bladder resections in the urology suite is feasible and lets envision high value for the patient.

Real-time analysis of colorectal polyps during coloscopy

The LLTech device was used this week under real coloscopy conditions at Cochin Hospital, Paris. Excised polyps were imaged within minutes by FFOCT in the coloscopy room, and the images transmitted to the pathologist office through the hospital network. The pathologist could thus give a feedback to the endoscopist during the coloscopy on the malignancy of the polyp.

Note: this experiment was conducted under a research study, which did not alter the patient management.
