Title: UTILITY OF BLUE LIGHT FLEXIBLE CYSTOSCOPY FOR BLADDER CANCER SURVEILLANCE AFTER INTRAVESICAL THERAPY
Presenter:
Session and Date: PD-63: Bladder: Cancer Non-Invasive III:
Results were provided by two high-volume treatment facilities that perform Blue Light Flexible Cystoscopy (BLFC) and are participants in the Blue Light Cystoscopy with Cysview Registry. In this study, data was captured from 277 office based BLFC examinations in 136 patients who received intravesical BCG or chemotherapy, as part of standard of care treatment for non-muscle invasive bladder cancer (NMIBC).
From these examinations, a total of 52 office-based biopsies were taken, of which 23 (44%) were confirmed as malignant. BLFC identified all 23 malignancies, demonstrating 100% sensitivity for cancer detection in this cohort, whereas analysis by cytology identified only 3 of the 23 confirmed malignancies. Additionally, from the 277 total examinations, 23 (8%) were White Light Cystoscopy (WLC) normal and BLFC abnormal. Of these 23 discordant results, 16 had office-based biopsies and cancer was confirmed in 9 cases (56%), which would have been missed by WLC alone.
The study authors concluded that office-based BLFC helps improve early detection of recurrence in cases with normal WLC and can aid in surveillance of patients receiving intravesical therapy, enhance performance of office-based biopsy and increase early detection of BCG unresponsive disease.
"The results from this study show that use of Blue Light Cystoscopy with Cysview for patient surveillance improved the ability to detect recurrent disease in this high-risk, recently-treated patient cohort, which can significantly impact future treatment decisions," said Dr.

Title: ADVANCES IN ENDOSCOPIC TREATMENT OF BLADDER TUMORS
Presenter:
Session and Date: Plenary Session: Surgical Techniques:
In this presentation,
"The study results presented at this year's AUA meeting as well as the discussion on BLC in the Surgical Techniques presentation underscores how critically important it is for patients to receive the proper bladder cancer care whether they are having tumor resection in the hospital or follow-up procedures" said

About Bladder Cancer
Bladder cancer ranks as the seventh most common cancer worldwide with 1 720 000 prevalent cases (5-year prevalence rate)1a, 573 000 new cases and more than 200 000 deaths annually in 2020.1b
Approx. 75% of all bladder cancer cases occur in men.1 It has a high recurrence rate with an average of 61% in year one and 78% over five years.2 Bladder cancer has the highest lifetime treatment costs per patient of all cancers.3
Bladder cancer is a costly, potentially progressive disease for which patients have to undergo multiple cystoscopies due to the high risk of recurrence. There is an urgent need to improve both the diagnosis and the management of bladder cancer for the benefit of patients and healthcare systems alike.
Bladder cancer is classified into two types, non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), depending on the depth of invasion in the bladder wall. NMIBC remains in the inner layer of cells lining the bladder. These cancers are the most common (75%) of all BC cases and include the subtypes Ta, carcinoma in situ (CIS) and T1 lesions. In MIBC the cancer has grown into deeper layers of the bladder wall. These cancers, including subtypes T2, T3 and T4, are more likely to spread and are harder to treat.4

About Hexvix®/Cysview® (hexaminolevulinate HCl)
Hexvix/Cysview is a drug that preferentially accumulates in cancer cells in the bladder making them glow bright pink during Blue Light Cystoscopy (BLC®). BLC with Hexvix/Cysview improves the detection of tumors and leads to more complete resection, fewer residual tumors and better management decisions.
Cysview is the tradename in the
