The BCG Shortage
نویسنده
چکیده
In 2014, I was on the Board of Directors of the Society of Urologic Oncology (SUO) when Merck announced having shortages of Tice strain Bacillus Calmette Guerin (BCG), a critical “drug” for treating intermediate and particularly high risk non-muscle invasive (NMI) urothelial cancer (UC) of the bladder, including carcinoma-in-situ (CIS) and high-grade (HG), stage Ta and T1 disease after transurethral resection. This was the second time in three years that a shortage of BCG had occurred, the previous one occurring when Sanofi announced a shortage of Connaught strain BCG. Particularly with the Merck shortage, I became a de facto spokesman for the SUO, the American Urological Association (AUA) and the Bladder Cancer Advocacy Network (BCAN) on this matter, which greatly affected all urologists in the Americas and Europe (and more importantly, our patients with bladder cancer). I was in contact with representatives of the manufacturer (Merck) of Tice strain BCG, manufacturer (Sanofi) of the competing product – which had not yet gone back into production, the Food and Drug Administration (FDA) and of course, the SUO, BCAN and the AUA. During the shortage, the use of BCG, when one could obtain it, was primarily restricted to patients with CIS and HG NMI UCs – rather than for intermediate risk disease for which intravesical chemotherapy could be an “almost as good” substitute. Maintenance courses and repeat induction courses of BCG were curtailed, and urologists experimented with administering lower dosages of BCG (so that vials could be used on more than one patient). After six months the Tice strain BCG shortage eased but was still felt by some practices for several more months (four months

Therapeutic options in high-risk non-muscle-invasive bladder cancer during the current worldwide shortage of bacille Calmette-Guérin.
Optimal management of high-risk non-muscle-invasive bladder cancer during the current bacillus Calmette-Guérin (BCG) shortage is challenging. Although no evidence-based guidelines exist for this specific situation, current management options can be adapted for when BCG supplies are limited or when BCG is unavailable.
متن کاملHigh-Risk Non-Muscle-Invasive Bladder Cancer—Therapy Options During Intravesical BCG Shortage
Bladder cancer is the second commonest urinary tract malignancy with 70-80 % being non-muscle invasive (NMIBC) at diagnosis. Patients with high-risk NMIBC (T1/Tis, with high grade/G3, or CIS) represent a challenging group as they are at greater risk of recurrence and progression. Intravesical Bacilli Calmette-Guerin (BCG) is commonly used as first line therapy in this patient group but there is...
متن کاملAdverse events following immunisation with bacille Calmette-Guérin vaccination: baseline data to inform monitoring in Australia following introduction of new unregistered BCG vaccine.
In recent years there has been a global shortage of bacille Calmette-Guérin (BCG) vaccine and, from September 2012, unregistered vaccines have needed to be used in Australia (a Danish product initially until the end of 2015, and a Polish product used in some jurisdictions from early 2016). We examined rates and types of adverse events following immunisation (AEFI) with BCG vaccine reported to t...
متن کاملTumor-infiltrating immune cell subpopulations influence the oncologic outcome after intravesical Bacillus Calmette-Guérin therapy in bladder cancer
Although Bacillus Calmette-Guérin (BCG) is the most successful immunotherapy for high-risk non-muscle-invasive bladder cancer, approximately 30% of patients are unresponsive to treatment. New biomarkers are important to identify patients who will benefit most from BCG during a worldwide BCG shortage. Local immune cell subsets were measured on formalin-fixed, paraffin-embedded tissue sections of...
متن کاملRole of MicroRNAs in BCG Therapy by the Induction of Neutrophil Extracellular Traps in Bladder Cancer
The treatment of bladder cancer is usually performed by Bacillus Calmette-Guerin (BCG) instillation. BCG therapy is a common therapeutic method with fewer side effects compared with chemotherapy, radiotherapy, etc. BCG can also inhibit the progression and recurrence of bladder cancer by inducing apoptosis pathways, arrest cell cycle, autophagy, and neutrophil extracellular traps (NETs) formatio...
