Blue Light Cystoscopy and Bladder Cancer: Insights from ASCO GU 2025

On February 14, 2025, at the American Society of Clinical Oncology Genitourinary Cancers Symposium (ASCO-GU) in San Francisco, Photocure ASA, known as The Bladder Cancer Company, unveiled critical findings from its U.S. bladder cancer patient registry. The presentation centered on the application of Blue Light Cystoscopy (BLC) in non-muscle invasive bladder cancer (NMIBC) patients, highlighting how this advanced technology facilitates the detection of tumors that traditional white light cystoscopy (WLC) may overlook.

Study Overview

Presented by Alireza Ghoreifi from Duke University Medical Center, the abstract discussed the results derived from an extensive registry comprising 2,854 NMIBC patients utilizing BLC with Cysview. The findings revealed that 201 patients, equating to approximately 7%, exhibited malignant lesions exclusively identified through BLC despite previous WLC results showing no abnormalities. The types of lesions detected included carcinoma in situ (CIS), various grades of Ta tumors, and advanced classifications such as high-grade T1 and T2 lesions.

This remarkable increase in detection rates—9.3% of patients being upstaged to a more severe tumor classification due to BLC—paves the way for transformative changes in bladder cancer management strategies. Upstaging has significant implications for treatment decisions regarding intravesical therapies and could dictate the timing and necessity of radical cystectomies.

Implications for Treatment

The research serves as a springboard for future investigations into using Blue Light Cystoscopy as a cornerstone of precision diagnostics in NMIBC. With bladder cancer's notorious recurrence rate—up to 61% within the first year—enhancing diagnostic capabilities is essential for improving patient outcomes and quality of life.

Bladder cancer, being the eighth most common form of cancer globally, accounts for a large burden, particularly among men, with a substantial 1,949,000 prevalent cases as of 2022. The comprehensive management of this cancer type, particularly NMIBC, is crucial as it remains confined to the bladder's internal layers.

About Photocure ASA and Blue Light Cystoscopy

Photocure ASA's registry contributes resilient data towards understanding bladder cancer treatment advances, aiming to enroll a total of 4,400 patients. Their flagship product, Cysview (or Hexvix in other markets), is designed to preferentially accumulate in cancer cells, illuminating them during BLC, a method proven to enhance tumor detection and assist in more effective surgical interventions.

In conclusion, the incorporation of Blue Light Cystoscopy into routine bladder cancer care promises to refine treatment approaches, reduce recurrence, and improve patients’ prognostic outcomes through precise and timely interventions. As the field progresses, continued exploration into innovative diagnostic technologies will be paramount for addressing the challenges posed by bladder cancer.
