Urethral Cancer - Stages and Types of Urethral Cancer

A rare type of urological cancer, urethral cancer arises from the cells that line the urethra, a thin, tube-like structure that transports urine out of the body. There are different types of urethral cancer, depending on the cell type that it arises from. It is a highly treatable cancer and usually has a good prognosis, provided it is diagnosed in the early stages.

Learning about the different aspects of urethral carcinoma can help one make informed decisions and put onself a step ahead of urethra cancer.

What is Urethral Cancer?

Urethral cancer, or urethral carcinoma, is a rare malignancy that develops in the tissues of the urethra. It occurs when the cells present in the urethral lining start dividing abnormally due to cancer-driving DNA mutations and forms a mass. If left untreated, this cancer can spread to nearby and far-off regions in the body and cause health complications. Hence, it is crucial to opt for regular screening, be mindful of the early symptoms of this cancer, and see a doctor if any persistent symptoms are experienced. Some types of urethra cancer is more common in men, and some types are more common in women.

How Common is Urethral Cancer?

Urethral cancer is considered rare, constituting a very small percentage of all urological cancers in both men and women. It accounts for approximately 1-2% of urinary tract cancers. Those with a prior history of any urological malignancy have a relatively higher risk of developing urethral carcinoma.

Different Types of Urethral Cancer

Urethra cancer is categorized into various types based on the cell type that originates from. Some of these types are common than others. The treatment approach for these types depends on the their stage during diagnosis and individual patient parameters. The following are the different types of urethral cancer:

Transitional (Urothelial) Cell Carcinoma

Transitional cell carcinoma, or urothelial cell cancer, originates from the transitional cells lining the urethra. It is the most common type of urethra cancer and is often associated with a history of bladder cancer. Treatment approaches may involve surgery, chemotherapy, or radiation therapy, depending on the stage and extent of the disease.

Squamous Cell Carcinoma

Squamous cell carcinoma of the urethra develops from the flat, thin cells lining the organ. This type is commonly found to arise from the cells close to the urethral opening. Chronic irritation or inflammation may increase the risk of squamous cell carcinoma of the urethra. Treatment strategies may include surgery and, in advanced cases, a combination of chemotherapy and radiation therapy.

Adenocarcinoma

Adenocarcinoma arises from the glandular cells present in the urethra. Although less common than transitional and squamous cell carcinomas, adenocarcinoma poses unique challenges in diagnosis and management. Treatment may involve surgery and additional therapies, depending on the extent of the cancer.

What are the Stages of Urethral Cancer

Urethral cancer staging is an important step before treatment planning. It helps specialists understand the extent of this disease. Different urethral cancer stages have their own distinct characteristic features and these play an important role in deciding the right treatment approach. Urethral carcinoma is staged based on two parameters - their location and TNM factors.

Urethral Cancer Stages On The Basis of Location

The following are the different urethral cancer stages based on the location of the tumor:

Anterior Urethral Cancer

Anterior urethral cancer occurs in the front portion of the urethra, which includes the external opening and extends to the region just beyond the penis or clitoris. This cancer subtype is superificial and is located in the easily-accessible location. This makes the treatment relatively less complex.

Posterior Urethral Cancer

Posterior urethral cancer is situated in the deeper, inner part of the urethra, closer to the bladder. This type may be more challenging to detect early due to its location, potentially requiring advanced diagnostic and treatment approaches.

Stages of Urethral Cancer

The following are the different urethral cancer stages based on the extent of the disease’s spread:

Stage 0 Urethral Cancer

Stage 0, also known as carcinoma in situ (CIS), indicates that abnormal cells are present in the inner lining of the urethra but have not invaded deeper tissues. Stage 0 urethra cancer is highly treatable.

Stage 1 Urethral Cancer

Stage 1 is indicated by the presence of a localized tumor in the urethra and has not spread to nearby tissues or lymph nodes. Stage 1 urethral tumors is easily treatable.

Stage 2 Urethral Cancer

Stage 2 signifies that the cancer has advanced beyond the confines of the urethra but is still limited to nearby structures. It often demands a multimodal treatment approach.

Stage 3 Urethral Cancer

In stage 3, the cancer has spread further into nearby tissues and may involve lymph nodes. Stage 3 urethral cancer often demands a multimodal treatment approach, which helps in treating the primary tumor and the potential metastasis.

Stage 4 Urethral Cancer

Stage 4 urethral cancer has spread to distant organs or tissues. Stage 4 urethral malignancy may require a more aggressive approach, combining various treatment modalities to manage both the primary tumor and distant metastases. Palliative care may also be recommended to manage symptoms.

Conclusion

Despite being a rare malignancy, urethral cancer can pose a serious health burden if not managed appropriately. Early detection and a comprehensive treatment plan significantly impact outcomes. Understanding urethral malignancies involves recognizing its types, stages, and various treatment approaches tailored to individual cases.

Frequently Asked Questions

Life expectancy in urethral cancer varies based on factors like stage, treatment response, and overall health. Early-stage cancers have better survival rates than advanced-stage cancers. Timely diagnosis and appropriate interventions play a pivotal role in improving survival rates and the overall prognosis.

Urethral cancer is rare, comprising a small percentage of urological cancers. It accounts for less than 1% of all types of cancer. The exact prevalence varies globally, emphasizing the importance of awareness, timely detection, and appropriate treatment.

Survival rates in urethral cancer depend on several factors, including stage, treatment efficacy, and individual health. The survival rates and the overall clinical outcomes are excellent for early-stage cancers. In recent years, advances in treatment options have positively impacted outcomes, and a multidisciplinary approach enhances the potential for extended survival.

Urethra cancer's aggressiveness varies by type and stage. Some types of urethral carcinoma are invasive and have a rapid growth rate. These types need a relatively more complex treatment approach to be managed effectively.

The incidence of urethral carcinoma is relatively low, constituting a small percentage of all urological cancers. Individuals with specific risk factors associated with urethral carcinoma have a higher chance of developing this cancer.

The commonly observed symptoms in women include blood in the urine, painful urination, difficulty urinating, frequent urination, unusual discharge from the urethra, a lump in the genital area, pain during sexual intercourse, vaginal discomfort, and changes in the vaginal discharge.
