What is the purpose of this trial?

This trial tests a new method to detect cervical dysplasia (abnormal cell growth on the cervix) using Multimodal Optical Imaging. Researchers compare it to a standard test that detects HPV, a virus linked to cervical cancer. The goal is to determine if this new imaging method is more accurate and reliable. Women who have had an abnormal cervical cancer screening test and have not had their cervix removed might be suitable candidates for this study. As an unphased trial, this study offers the chance to contribute to innovative research that could enhance early detection methods for cervical dysplasia.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this multimodal optical imaging is safe for detecting cervical dysplasia?

Research shows that multimodal optical imaging is generally easy for patients to handle and helps detect early changes in the cervix. One study found it provides a quick and simple check-up at the examination site, without requiring extra tests.

Importantly, studies reviewed have reported no major adverse side effects, suggesting the procedure is safe for patients. The imaging is non-invasive, meaning it doesn't involve cutting or surgery, reducing risk for participants.

Overall, existing research supports the safety of multimodal optical imaging for identifying cervical dysplasia, a condition where cervical cells appear abnormal under a microscope. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about multimodal optical imaging for cervical dysplasia detection because it combines mobile colposcopy with high-resolution imaging, offering a more detailed view of cervical tissue than traditional methods like Pap smears and standard colposcopies. This technique allows for more precise identification of abnormal cells during a colposcopy examination, potentially leading to earlier and more accurate detection of cervical dysplasia. By improving visualization, this method aims to enhance the accuracy of diagnoses and could reduce the need for unnecessary biopsies, making the process less invasive and more comfortable for patients.

What evidence suggests that this multimodal optical imaging is effective for detecting cervical dysplasia?

Research has shown that a new method called multimodal optical imaging, tested in this trial, could improve early detection of cervical cancer. One study found that this method correctly identified 97% of cases, compared to 72% with the traditional Pap smear, demonstrating its effectiveness in spotting cervical cancer and its early stages. Another study showed that it outperformed colposcopy, a common procedure for examining the cervix. These findings suggest that multimodal optical imaging might be a more effective tool for early detection of cervical issues. ^{1 2 3 6 7}

I am a woman aged between 25 and 49.

Exclusion Criteria

I have had a total hysterectomy.

What Are the Treatments Tested in This Trial?

Interventions

• Multimodal Optical Imaging

Trial Overview This study tests the accuracy of a lateral flow test for HPV against the GeneXpert HPV test and evaluates how well a multimodal optical imaging system detects cervical dysplasia compared to histopathology (tissue examination).

How Is the Trial Designed?

Group I: Multi-Modal Optical Imaging Experimental Treatment 1 Intervention

Multi-modal imaging (mobile colposcopy and high resolution imaging) of study participants will be performed during the colposcopy examination. Cervical biopsies will be performed using biopsy forceps per standard protocols.

Published Research Related to This Trial

High-resolution microendoscopy (HRME) significantly improves the ability to differentiate between neoplastic and non-neoplastic colorectal polyps, with diagnostic accuracy increasing from 63% to 96% as the endoscopist gains experience with the technique over 162 polyps.

The study shows that even endoscopists without prior HRME experience can achieve over 90% accuracy in identifying neoplastic polyps after imaging just 40 polyps, indicating HRME's potential as a valuable tool in colorectal cancer screening.

The High Resolution Microendoscope (HRME) demonstrated a sensitivity of 86% and specificity of 87% in detecting neoplastic tissue in a pilot study involving 26 patients in Botswana, indicating its effectiveness as a screening tool for cervical cancer.

This optical imaging technology offers a low-cost and easy-to-use alternative for cervical cancer screening in developing countries, where traditional methods may be limited due to lack of resources and trained personnel.

Hyperspectral imaging (HSI) has been shown to effectively differentiate between cervical intraepithelial neoplasia (CIN) and normal tissue in a study involving 41 patients, demonstrating high statistical significance in the results.

The use of commercially available HSI systems could provide a contact-free and examiner-independent method for diagnosing CIN, addressing the shortage of qualified physicians for cervical cancer screening.

Optical spectroscopy technologies, including fluorescence and reflectance spectroscopy, show diagnostic performance comparable to colposcopy for detecting cervical neoplasia, based on a review of 26 studies involving various device approaches and populations.

While optical spectroscopy could potentially aid in localizing lesions and serve as an adjunct to colposcopy, its use for ASCUS triage and primary screening has not been adequately evaluated to confirm its effectiveness in those roles.

A review of 26 clinical trials on fluorescence and reflectance spectroscopy for diagnosing cervical neoplasia found that larger sample sizes and older patient populations (over 50 years) were associated with decreased performance of diagnostic devices.

The study highlighted that as clinical trials progressed from pilot to Phase III, the variability in performance increased, indicating that factors like sample size and patient demographics significantly impact the efficacy of these diagnostic methods.

Fluorescence and reflectance spectroscopy, whether used in point probe or multispectral imaging, show similar diagnostic efficacy for detecting cervical neoplasia, based on a review of 26 studies, although definitive conclusions about their combined effectiveness are still unclear.

Most studies focused on diagnostic populations with existing cervical abnormalities, highlighting a lack of research on screening populations, which limits the understanding of these technologies' effectiveness in early detection.
