Enhanced Imaging in Bladder Cancer: Fluorescence Cystoscopy and Molecular Diagnostics

Area of Science:

• Urology
• Oncology
• Medical Imaging

Background:

• Bladder cancer has high recurrence rates, necessitating long-term surveillance.
• Conventional white-light cystoscopy (WLC) may miss subtle lesions like carcinoma in situ.
• Enhanced imaging techniques aim to improve diagnostic accuracy for bladder lesions.

Purpose of the Study:

• To evaluate fluorescence-based diagnostic techniques for bladder lesions.
• To assess autofluorescence imaging supported by numerical color value (NCV) analysis.
• To improve the detection and assessment of bladder lesions.

Main Methods:

• Utilized the Onco-LIFE optical imaging system for white-light and autofluorescence visualization.
• Included 30 patients with non-muscle-invasive bladder cancer or suspected lesions.
• Analyzed fluorescence signals (red/green channels) and NCV for tissue characteristics.

Main Results:

• Fluorescence imaging enhanced visualization of suspicious mucosal changes compared to WLC.
• Distinct fluorescence patterns differentiated malignant lesions, inflammatory changes, and carcinoma in situ.
• NCV analysis quantitatively assessed fluorescence signals, aiding differentiation of pathological from normal tissue.

Conclusions:

• Fluorescence cystoscopy and autofluorescence imaging are valuable tools for detecting bladder lesions.
• Integrating enhanced imaging with quantitative analysis can improve diagnostic sensitivity.
• Further development may expand the role of fluorescence diagnostics in bladder cancer management.
