"In addition to this activity, two abstract presentations were presented as part
of the EAU scientific program that feature the blue light cystoscopy procedure:
Immunological changes following blue light cystoscopy with hexaminolevulinate in
bladder cancer (A0431 - Sunday 10:45)
The project conducted at Department of Molecular Medicine, Aarhus University
Hospital, Denmark, presents results from a pilot study of bladder cancer
patients, showing that blue light cystoscopy with Hexaminolevulinate (HAL)
during TURBT* may influence the immune cell composition and tumor
microenvironment. Preliminary findings suggest that BLC-guided TURBT changes the
expression of immune cells of both the adaptive and innate immune system
compared to WLC-guided TURBT. Further studies are required to validate the
clinical impact of these observations.

Blue Light Cystoscopy Delays Time to Recurrence in Non-Muscle Invasive Bladder
Cancer Patients Treated in a Real-World Setting (A0710 - Sunday 15:45)
Real-world data taken from the Blue Light Cystoscopy with Cysview[®] Registry
(Clinicaltrials.gov; NCT02660645), the largest non-muscle-invasive bladder
cancer registry in the U.S., showed that use of BLC significantly decreased the
risk of recurrence and prolonged time to recurrence compared to White Light
alone (HR 0.33; 95% 95% CI 0.2-0.40, p<0.0001). Additionally, BLC in patients
with primary tumors extended time to recurrence compared to recurrent patients
(HR 1.12; 95% CI 0.89-1.41, p<0.001), suggesting that the earlier use of BLC
might have more favorable long-term outcomes in a real-world setting.

“These new study results continue to emphasize the importance of performing a
thorough TURBT using Blue Light Cystoscopy in the treatment of bladder cancer,
and also demonstrate the strong interest from the scientific community to
investigate Hexvix[®]/Cysview’s potential immunologic effects in bladder cancer
management. BLC has been shown to clinically increase TURBT quality, more
accurately stage disease for treatment, and enable better recurrence monitoring,
supporting the long-term utility to help improve the lives of patients with
bladder cancer,” said Dan Schneider, President and CEO of Photocure.
“As we continue to broaden the awareness of BLC with Hexvix throughout Europe,
it is a privilege to participate in the EAU congress, and to see so much
engagement from the scientific community and urologists alike. The expanding
number of scientific sessions featuring Blue Light is impressive this year. It
empowers us on our journey to bring this important product and procedure to even
more new users in Europe” added Susanne Strauss, Vice President and General
Manager Europe."
Indikasjon av terapeutisk effekt er ganske overbevisende.
