Effectiveness and Mechanism of Action

BCG bladder cancer treatment is considered one of the most effective therapies for non-muscle-invasive bladder cancer.

Mechanism of Action

The Bacillus Calmette-Guérin (BCG) vaccine is a live attenuated strain of Mycobacterium bovis, which is closely related to the bacteria that cause tuberculosis. When used as a treatment for bladder cancer, BCG activates the immune system to recognize and destroy cancer cells.

Key points:

  • BCG stimulates the body’s immune response to target cancer cells in the bladder.
  • It induces the release of cytokines that recruit immune cells to the site of the tumor.
  • The immune response triggered by BCG leads to the destruction of cancer cells and inhibits tumor growth.

Research has shown that BCG therapy can reduce the recurrence of superficial bladder cancer and prevent its progression to more advanced stages.

“BCG works by stimulating the immune system to attack and kill cancer cells in the bladder, making it a potent treatment option for non-muscle-invasive bladder cancer.”

According to a study published in the National Cancer Institute, BCG therapy has demonstrated a 70% to 90% success rate in preventing the recurrence of non-muscle-invasive bladder cancer.

Effectiveness of BCG Therapy

Several clinical trials have confirmed the effectiveness of BCG therapy in reducing tumor recurrence and improving overall survival rates in patients with non-muscle-invasive bladder cancer.

Study Findings
SWOG Intergroup Trial BCG therapy reduced the risk of disease recurrence by 27% compared to standard treatments.
European Organization for Research and Treatment of Cancer Patients treated with BCG had a lower risk of cancer progression and death compared to those who did not receive BCG.

These findings highlight the significant impact of BCG therapy on the outcomes of bladder cancer treatment and emphasize its role in preventing disease recurrence and progression.

Administration and side effects of BCG therapy

BCG therapy is typically administered as an intravesical treatment, meaning it is directly instilled into the bladder through a catheter. The process involves a series of BCG treatments over a specified period, with the schedule determined by the healthcare provider based on the individual patient’s condition.

During the administration of BCG therapy, patients may experience some common side effects which are usually mild to moderate in severity. These side effects include:

  • Urinary Symptoms: Patients may experience increased frequency or urgency of urination, discomfort or burning sensation during urination, or blood in urine.
  • Flu-Like Symptoms: Some patients may develop flu-like symptoms such as fever, chills, or body aches shortly after receiving BCG therapy.
  • Bladder Irritation: BCG therapy can cause irritation of the bladder lining, leading to symptoms like bladder spasms, pain in the lower abdomen, or urinary incontinence.
