The paper evaluates the available data as well as our own on use of autofluorescence bronchoscopy in conjunction with spectrometric examination. We used qualitative and quantitative assessment of images obtained by conventional and autofluorescence (ClearVu Elite) means in real time. Our double-stage study evaluated sensitivity and specificity of autofluorescence bronchoscopy in diagnosing lung cancer as well as constructed spectrometric curves (ROC) and areas under them (AUC). Endoscopy was used in 171 patients with central lung cancer. Autofluorescence bronchoscopy established high sensitivity--94.74% (95%CI: 80.9-99%) and sufficient specificity--79.95% (95%CI: 75.8-83.6%). Application of a wide range of spectrometric coefficients contributed to high specificity thus reducing the number of biopsies as well as the injury from the treatment. The AUC for a best predictive index was 0.89 (99%: 0.83-0.95).

Fine-needle aspiration biopsy is crucial for modern diagnostics of endoscopic procedures and thus an efficient and reliable method for increasing biopsy yields is urgently needed. In our study, we address the limited availability and high price of the rapid onsite evaluation (ROSE) technique by introducing the technique of near-infrared on-site evaluation (NOSE) consisting of spectral measurement of near-infrared radiation (NIR) transmitted through the evaluated material. For this purpose, we designed a special optical probe consisting of two fibres, of which one is a source fibre and the second is a detector fibre.

Article Synopsis
- The study discusses the importance of detecting suspect lesions in endoscopic video for patients at risk of lung or colorectal cancer, highlighting the challenges of manual inspection.
- The authors introduce a deep learning model called ESFPNet, which utilizes a Mix Transformer and an Efficient Stage-Wise Feature Pyramid to enhance real-time detection and segmentation of lesions in endoscopic videos.
- ESFPNet outperforms existing models in lesion segmentation for both autofluorescence bronchoscopy and colonoscopy datasets, with greater efficiency and generalizability, suggesting its potential application in other areas of medical imaging.

Background: Endobronchial squamous cell carcinoma is one of the most common types of tumors located inside the tracheobronchial tree. Patients often present in advanced stages of the disease, which most often leads to a targeted therapeutic attitude of pneumonectomy. Practicing lung parenchyma-preserving surgery led us to undertake this review.
