What Patients Should Know About Their Stage 1 Bladder Cancer

Receiving a diagnosis of stage 1 urothelial carcinoma (bladder cancer) can feel overwhelming, but at this stage, the cancer is highly treatable. Stage 1 means the cancer has grown into the inner lining of the bladder (the lamina propria) but has not yet reached the thick muscle wall.

Here is an overview of the journey ahead to help guide your upcoming conversations with your medical team.

Overview of stage 1 urothelial carcinoma

Urothelial carcinoma is the most common type of bladder cancer. In stage 1, the tumor is "non-muscle invasive." While the cancer is localized, urothelial tumors have a tendency to recur (come back) elsewhere in the bladder lining. Therefore, the primary goals of your care are to remove the existing tumor and prevent it from returning or progressing to a more advanced stage.

Receiving a diagnosis of stage 1 urothelial carcinoma

To confirm the stage and grade of the cancer, oncologists typically use a combination of the following:

• Cystoscopy: A procedure where a small camera is inserted into the bladder to visualize the tumor.
• TURBT (Transurethral Resection of Bladder Tumor): This is often both a diagnostic tool and the first step of treatment. A surgeon removes the tumor through the urethra to be examined by a pathologist.
• Imaging: CT scans or MRIs may be used to ensure the cancer has not spread beyond the bladder lining.
• Urine Cytology: Examining a urine sample under a microscope to look for cancer cells.

Treatment Options for stage 1 urothelial carcinoma

Treatment for stage 1 is usually focused on bladder preservation. Your team may recommend:

• TURBT: The gold standard for removing visible tumors.
• Intravesical Therapy: Instead of systemic chemotherapy (pills or IV), medication is delivered directly into the bladder via a catheter.
• BCG (Bacillus Calmette-Guérin): An immunotherapy that stimulates the immune system to attack cancer cells.
• Intravesical Chemotherapy: Drugs like mitomycin or gemcitabine are used to kill remaining cells.
• Surveillance: Frequent follow-up cystoscopies (typically every three to six months initially) to catch any recurrences early.

“When the cancer is classified as stage 1, it means the tumor has grown through the inner lining of the bladder but has not invaded the deep muscle layer of the bladder wall. Stage 1 is considered an early-stage cancer,” a recent article from CURE explained. “The goal of treatment for stage 1 urothelial carcinoma is typically to remove the tumor completely and prevent recurrence or progression.”

Potential side effects for stage 1 urothelial carcinoma treatment

Because treatments for stage 1 are often localized to the bladder, side effects are generally different from traditional "full-body" chemotherapy:

• Urinary Symptoms: Frequent urination, urgency or a burning sensation during urination (especially following BCG or TURBT).
• Blood in Urine: Common for a few days after procedures.
• Flu-like Symptoms: BCG can cause temporary fatigue, low-grade fever or chills as the immune system is activated.
• Bladder Irritation: Some patients feel a "cramping" sensation in the pelvic area.

What patients should understand

A stage 1 diagnosis is a pivotal moment where proactive treatment can lead to excellent long-term outcomes. However, it requires a commitment to long-term monitoring. Use this information to ask your oncologist about the grade of your tumor (low-grade versus high-grade) and whether BCG therapy is the right next step for your specific case.

Questions to ask your doctor about stage 1 urothelial carcinoma

• What was the "grade" of my stage 1 tumor, and how does that affect my risk of recurrence?
• How many rounds of intravesical therapy will I need?
• What is our long-term schedule for follow-up cystoscopies?
• Are there lifestyle changes (like smoking cessation) that can lower my risk?
