Life Expectancy of Elderly With Bladder Cancer

Bladder cancer occurs when cells in the bladder grow uncontrollably. While it can affect any age group, its incidence increases significantly with age, and the average age of diagnosis is 73. Approximately 90 percent of individuals diagnosed with this disease are over 55. A diagnosis can lead to many questions about the future, and this overview provides information on the outlook for an elderly person with bladder cancer.

Understanding Bladder Cancer Survival Statistics

When discussing life expectancy, healthcare professionals use survival rates. These are statistics based on large groups of people, not individual predictions. A common measure is the 5-year relative survival rate, which compares people with the same type and stage of cancer to the general population.

For bladder cancer at all stages combined, the overall 5-year relative survival rate is about 78.4 percent. These statistics are averages and vary by age. For adults aged 65 and older with localized bladder cancer, meaning it has not spread outside the bladder, the 5-year relative survival rate is 67%. The rate for those aged 75 and older across all stages is 71.1%.

Key Prognostic Factors in the Elderly

A person’s outlook is determined by factors related to the cancer and the individual’s health. The primary cancer-related characteristics are its stage and grade. The stage describes how far the cancer has spread, with a distinction between non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). NMIBC is confined to the bladder’s inner lining, while MIBC has grown into the deeper muscle wall, and NMIBC, which accounts for about 70% of new diagnoses, generally has a better prognosis.

Tumor grade refers to how abnormal the cancer cells appear under a microscope. Low-grade tumors are more similar to normal cells and tend to grow slowly, while high-grade tumors look more abnormal and are more likely to grow aggressively and spread. For example, the 5-year survival rate for cancer that is “in situ,” a type of high-grade NMIBC, is 97.2%, whereas for cancer that has spread to distant parts of the body, the rate drops to 8.8%.

The patient’s overall condition is another major consideration. Age itself is an independent prognostic factor. Pre-existing health issues, such as heart disease or diabetes, can influence both survival and the ability to tolerate certain treatments. Doctors often assess a patient’s “functional status,” which is a measure of their ability to perform daily activities. A lower functional status, sometimes referred to as frailty, can correlate with poorer outcomes and may limit more aggressive treatment options.

Treatment Considerations for Older Adults

Treatment for an elderly patient aims to manage the cancer while maintaining quality of life. The choice of treatment depends on the cancer’s stage, the patient’s health, and their preferences. For non-muscle-invasive tumors, a common procedure is a transurethral resection of bladder tumor (TURBT) to remove the tumor from the lining. This is often followed by intravesical therapy, where a drug like Bacillus Calmette-GuĂ©rin (BCG) is put directly into the bladder to prevent recurrence.

Muscle-invasive cancer may require more aggressive treatment. A radical cystectomy, the surgical removal of the bladder, is a standard approach but is a major operation with significant complications, especially for older adults. In some cases, chemotherapy or immunotherapy, which uses the body’s own immune system to fight cancer, may be used as an alternative to surgery or in addition to it. The decision weighs the potential benefits of a therapy against its risks and impact on the patient’s daily life.

Long-Term Outlook and Monitoring for Recurrence

Bladder cancer has a tendency to recur, making ongoing surveillance a standard part of care. This monitoring is designed to detect new tumors early, when they are most treatable. Follow-up care involves regular cystoscopy, where a camera is used to inspect the bladder lining. The frequency of these checks depends on the cancer’s initial risk assessment.

Living with treatment effects is another aspect of the long-term outlook. For instance, after a radical cystectomy, a new way for urine to exit the body must be created, which has a permanent impact on daily function and requires adjustment. Follow-up care also involves managing any lasting side effects of treatment and supporting the patient’s overall quality of life.
