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.
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.
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.
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 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 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 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.
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.
The following are the different urethral cancer stages based on the location of the tumor:
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 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.
The following are the different urethral cancer stages based on the extent of the disease’s spread:
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 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 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.
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 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.
urethral cancer presents with various symptoms. Also, many symptoms of urethral cancer overlap with those of many other urological problems. Therefore, it is important to pay attention to these symptoms, especially when they are persistent, and consult a specialist for a thorough evaluation.
Urethral cancer is considered rare, comprising only a small fraction of all urological cancers. Its incidence is higher in men than women. Being aware of the different symptoms and risk factors is crucial for the early detection and timely treatment of urethral cancer.
People often wonder, "What are the signs of urethral cancer?" "What are the early signs?" "What are the symptoms of advanced-stage urethral cancer? Urethral cancer presents with multiple symptoms; some may be seen in the early stages and some in the advanced stages. Often, urethral cancer symptoms overlap with the symptoms of certain benign urological conditions, such as urethral stricture, urethral caruncle, and urethral diverticulum, and complications from indwelling catheterization. Hence, a prompt evaluation of symptoms is always recommended for a definitive diagnosis. The following are the commonly observed urethral cancer symptoms:
Hematuria, or blood in the urine, is one of the most common urethral cancer symptoms. It may present as visible blood or be microscopic.
Patients with urethral cancer may have palpable lumps or abnormal growths along the urethra, which may indicate the development of tumors.
Unexplained discharge from the urethra, especially if persistent and accompanied by other urethral cancer signs, should not be ignored, as it could indicate the presence of urethral cancer.
Changes in urinary patterns, including pain, a weakened stream, or dribbling during urination, may indicate the presence of urethral cancer.
Frequent urination, unrelated to factors such as increased fluid intake, could also be one of the urethral cancer signs.
Enlarged lymph nodes in the groin may signify the spread of urethral cancer. Palpable or visible lymph node enlargement should not be ignored, as it could be one of the urethral cancer signs.
In some cases, the tumor growth can cause urethral obstruction, which in turn may lead to a weakened urine stream.
Pelvic pain, whether constant or intermittent, could be one of the urethral cancer symptoms.
The presence of a lump or thickness in the perineum or penis may also be one of the urethral cancer symptoms.
Advanced urethral cancer may lead to the obstruction of lymphatic vessels, resulting in swelling in the legs or feet.
Many often wonder, “What causes urethral cancer?” While the exact cause is yet to be identified, we do know that certain factors can increase the risk of urethral cancer. Individuals with these risk factors have a higher chance of developing urethral cancer. The following are some of the possible urethral cancer causes:
Certain sexually transmitted infections, such as HPV, chlamydia, and gonorrhea, can increase the risk of urethral cancer development. That said, one must know that not all individuals with STIs develop urethral cancer. The ability of chronic STIs to increase the risk of urethral cancer makes them one of the possible urethral cancer causes.
Infection caused by human papillomavirus (HPV), especially high-risk strains, is also considered one of the possible urethral cancer causes.
Cigarette smoking has been linked to an increased risk of developing urological cancers, including urethral cancer.
Urethral strictures, or narrowings of the urethra, are identified as one of the possible urethral cancer causes in some cases. Chronic irritation and inflammation associated with strictures may contribute to the development of urethral malignancies.
While rare, urethral caruncles, which are benign growths near the urethral opening, may be associated with chronic irritation and inflammation, potentially increasing the risk of cancer.
Urethral diverticula, pouch-like structures in the urethral wall, may create an environment suitable for the development of urethral cancer.
Long-term use of indwelling catheters, often necessary for certain medical conditions, may pose a risk for urethral cancer.
Consulting an oncologist is essential when facing potential urethral cancer signs. If you are experiencing symptoms like urination difficulties, blood in the urine, and persistent discomfort in the pelvic region, seeking prompt medical attention is crucial. Having risk factors, such as HPV infection, a history of smoking, or previous urethral conditions, may increase one’s urethral cancer risk. In such cases, it is important to proactively opt for regular health check-ups and cancer screening.
Diagnosing and treating urethral cancer are best done with meticulous approaches, including lab tests, imaging tests, and biopsies. A comprehensive and personalized approach wherein individual patient parameters are considered before charting a treatment is the ideal approach to the successful management of urethral cancer. Surgery, chemotherapy, and radiation therapy are the commonly recommended urethral cancer treatment options.
The following are the different tests recommended for urethral cancer diagnosis:
The diagnosis of urethral cancer begins with a thorough clinical history and physical examination. Doctors gather information about symptoms, risk factors, and overall health. A physical exam aids in identifying any visible abnormalities or signs that may guide subsequent diagnostic steps.
A pelvic exam is a crucial component of urethral cancer diagnosis, focusing on the examination of the pelvic organs, including the urethra. This examination helps detect any irregularities, growths, or abnormalities that may indicate the presence of urethral cancer.
In cases where urethral cancer may affect nearby structures, a digital rectal exam is conducted to examine the prostate gland, rectum, and surrounding tissues. This examination provides valuable information about the extent of the cancer and the potential involvement of nearby structures.
A blood test, including routine bloodwork and specific markers, may be recommended to assess overall health and look for abnormalities that indicate the presence of urethral cancer. Elevated levels of certain markers may indicate the presence of cancerous cells.
Urinalysis involves the examination of urine for abnormalities, including the presence of blood or unusual cells. The presence of blood is a common indicator of urethral cancer, making urinalysis an essential diagnostic tool.
Urine cytology involves the microscopic examination of urine samples to identify abnormal cells shed by the urethra. This test assists in confirming the presence of cancerous cells and contributes to the overall diagnostic assessment.
Cystoscopy is a minimally invasive procedure that allows direct visualization of the urethra and bladder using a thin, flexible tube with a camera. This test aids in urethral cancer diagnosis by identifying abnormalities, tumors, or irregularities in the urethra.
Ureteroscopy involves the use of a thin, flexible scope to examine the urethra and the upper urinary tract (ureter). This diagnostic tool aids in urethral cancer diagnosis by assessing the extent of cancer involvement and guiding treatment planning.
A CT scan provides detailed cross-sectional images of the pelvis and surrounding structures. This imaging modality is used in urethral cancer diagnosis for staging, determining the extent of spread, and treatment planning.
A biopsy is a confirmatory test recommended for urethral cancer diagnosis. It involves the removal of a small tissue sample from the suspected cancerous area. Cystoscopy and ureteroscopy are often used to obtain biopsy samples. The tissue sample is then examined under a microscope to confirm the presence of cancer, identify its type, and devise a personalized urethra cancer treatment plan accordingly.
Yes, urethral cancer is treatable, and the prognosis often depends on various factors such as the stage at diagnosis, the type of cancer, and the overall health of the individual. Timely detection and a personalized treatment approach play a significant role in optimizing clinical outcomes.
Urethral cancer or uethral carcinoma treatment is best done with a multidisciplinary and personalized approach. This approach involves specialists from different disciplines going through each case and recommending a personalized care approach that is best for that particular case. Along with optimizing clinical outcomes, a personalized care approach also prioritizes the patient’s comfort and overall well-being throughout the treatment. The specialists often recommend one or more of the following for urethral cancer treatment:
Surgery is a primary treatment for osteosarcoma, involving the removal of the cancerous tumor along with a margin of healthy tissue. Depending on the tumor's location and size, surgical approaches may include limb-salvaging procedures or amputation. The goal is to eradicate the cancer while preserving functionality and minimizing the long-term impact on the patient's quality of life. This is the most commonly recommended treatment for osteosarcoma. After surgery, depending on the treatment response shown, the doctors may recommend additional treatment to improve the overall effectiveness of the treatment.
Chemotherapy for urethral cancer involves the use of drugs to kill or inhibit the growth of cancer cells. It may be administered before surgery (neoadjuvant), after surgery (adjuvant), or as the primary treatment for advanced or metastatic cases. Chemotherapy aims to target and eliminate cancer cells throughout the body.
Radiation therapy utilizes high-dose radiation to target and destroy cancer cells. Radiotherapy for urethral cancer is either administered alone or in combination with surgery or chemotherapy. Radiation therapy may be external or internal, depending on the specific characteristics of the cancer.
Immunotherapy involves re-engineering the body's immune system to recognize and attack cancer cells. Immunotherapy is not a standard treatment for urethral cancer, as investigations are still going on to study the efficacy of immunotherapy against urethral cancer. Those who have exhausted all their urethral cancer treatment options may consider opting for immunotherapy directly or via clinical trials.
