Confocal Microscopy: Pioneering the Quest for Biomarkers in Chemotherapy-Induced Neuropathy
Introduction to Chemotherapy-Induced Neuropathy
Chemotherapy-induced peripheral neuropathy (CIPN) is a significant and often debilitating side effect of certain cancer treatments. Patients suffering from CIPN frequently experience severe discomfort, including numbness, weakness, and pain in their extremities, drastically affecting their quality of life. The urgency to find innovative solutions for this condition is critical, and groundbreaking research is underway at the University of Arizona.
A Major Breakthrough: Funding for Innovative Research
Recently, a researcher from the University of Arizona Comprehensive Cancer Center secured an impressive $2.4 million grant from the National Cancer Institute. This funding aims to develop a noninvasive confocal microscope designed specifically to investigate the nerve endings of cancer patients battling CIPN. The hope is to identify potential biomarkers that could transform how this debilitating condition is understood and treated.
Why Meissner Corpuscles Matter
At the heart of this research lies the Meissner corpuscle, a type of nerve ending sensitive to light touch and low vibrations. Research indicates that cancer patients experiencing CIPN often show a reduced number of these critical structures. Dongkyun Kang, PhD, an associate professor of optical sciences at the U of A, seeks to use confocal microscopy to visualize and quantify Meissner corpuscles, aiming to establish them as a potential imaging biomarker for early detection of CIPN.
The Vision for Change in Patient Care
Dr. Kang emphasizes the impact of CIPN on cancer patients:
"CIPN symptoms can cause high levels of discomfort and present multiple challenges in the daily lives of cancer patients." His innovative approach could lead to earlier detection of CIPN, potentially stopping symptoms from worsening and even preventing the condition altogether.
Pioneering Low-Cost Microscopy
Kang’s lab has made remarkable strides over the past seven years by pioneering low-cost confocal microscopy. This breakthrough makes advanced imaging techniques accessible across a wide spectrum of clinical environments, opening doors for improved patient care.
"This study will build the evidence that our noninvasive microscopy approach can provide quantitative imaging biomarkers for CIPN monitoring, treatment, and research."

A Shift Toward Objective Diagnostics
Dr. Kang’s research signifies a pivotal shift in the diagnostic landscape. He aims to replace traditional subjective assessments—like patient and clinician questionnaires—with more objective, quantitative biomarkers. This evolution towards personalized care could fundamentally change how CIPN is managed.
Collaborative Excellence: A Team of Experts
Kang is not alone in this endeavor. His research team boasts co-investigators from various esteemed institutions, including:
- Clara Curiel-Lewandrowski, MD – Professor of medicine, U of A College of Medicine
- Denise Roe, DrPH – Professor at the Mel and Enid Zuckerman College of Public Health
- Collaborators from Guy’s and St. Thomas’ Hospital and Memorial Sloan Kettering Cancer Center.
The collective expertise of these professionals enhances the potential impact of the research on a global scale.
Looking Ahead: The Potential for Global Impact
Dan Theodorescu, MD, PhD, director of the U of A Cancer Center, expresses enthusiasm for this innovative study:
"The work Dr. Kang has been doing exemplifies the Cancer Center’s approach to precision prevention and therapy. I’m excited to see how his study evolves, especially given its potential for global impact."
Conclusion: A New Era of Understanding CIPN
With vital support from the National Cancer Institute, research efforts led by Dr. Kang are diving deep into the complexities of chemotherapy-induced peripheral neuropathy. The results of this revolutionary work could reshape patient care and improve the lives of countless cancer survivors.
