Introduction: Cancer ranks as the second most prevalent cause of death worldwide, responsible for approximately 9.6 million deaths annually. Approximately one out of every six deaths is caused by cancer. About 80% of cancer deals with epithelial tissues located on the outer lines of the body cavity.
Areas Covered: This review study selected and analyzed recent works in the field of High Resolution Microendoscopy (HRME) that have been used to diagnose cancer in various organs such as cervical, esophageal, head & neck, and gastrointestinal.
Expert Opinion: The HRME modality will play a vital role in improving the diagnostic accuracy of carcinoma. HRME has shown promising statistical outcomes for diagnosing carcinoma, enabling the clinician to gain additional information before performing conventional tissue biopsy. A multimodal probe consisting of a macroscopic investigation aided by HRME modality for microscopic investigation can significantly reduce the number of unnecessary biopsies leading to overall improvement in patient wellness. The new directions of the HRME research would be in the light source and detection configuration, increasing the number of optical fiber cores, which improves the resolution of the image, AI-assisted automatic quantification of the key HRME parameters, and clinical studies with newer near-infrared regime-based contrast agents.

Cervical cancer remains a leading cause of cancer death among women in low-and middle-income countries. Globally, cervical cancer prevention programs are hampered by a lack of resources, infrastructure, and personnel. We describe a multimodal mobile colposcope (MMC) designed to diagnose precancerous cervical lesions at the point-of-care without the need for biopsy.

Conventional cystoscopy plays an important role in detection of bladder cancer; however, it is difficult to differentiate benign and neoplastic lesions based on cystoscopic appearance alone. Advanced microscopic modalities, such as confocal laser endomicroscopy and optical coherence tomography, have been shown to provide critical histopathologic information to help identify neoplastic bladder lesions in real time, but their availability and clinical adoption are limited due to a high cost. In this study, we present the first use of a novel and low-cost ($ <5000) confocal high-resolution microendoscope (confocal HRME) for imaging of bladder lesions.

Early detection of oral cancer and oral premalignant lesions (OPL) containing dysplasia could improve oral cancer outcomes. However, general dental practitioners have difficulty distinguishing dysplastic OPLs from confounder oral mucosal lesions in low-risk populations. We evaluated the ability of two optical imaging technologies, autofluorescence imaging (AFI) and high-resolution microendoscopy (HRME), to diagnose moderate dysplasia or worse (ModDys) in 56 oral mucosal lesions in a low-risk patient population, using histopathology as the gold standard, and in 46 clinically normal sites.

Objectives: High-resolution microendoscopy (HRME) is an optical imaging modality that allows real time imaging of epithelial tissue and structural changes within. We hypothesize that HRME, using proflavine, a contrast agent that preferentially stains cell nuclei and allows detection of cellular morphologic changes, can distinguish sinonasal pathology from uninvolved mucosa, potentially enabling real-time surgical margin differentiation.
Study Design: Ex vivo imaging of histopathologically confirmed samples of sinonasal pathology and uninvolved, normal sinus epithelium.
