Bladder Colonic Type Adenocarcinoma: A Rare and Aggressive Form of Cancer

Bladder colonic type adenocarcinoma is a rare and aggressive form of cancer that affects the urinary bladder. It is characterized by the presence of glandular structures resembling those found in colonic adenocarcinoma (colorectal cancer) [5][8]. This type of cancer is also known as intestinal-type adenocarcinoma.

Morphological Characteristics

The tumor cells in bladder colonic type adenocarcinoma are typically tall and columnar, with abundant eosinophilic cytoplasm. They may exhibit necrosis and are morphologically identical to those found in colonic adenocarcinoma [5]. The presence of glandular structures and intracellular mucin is a hallmark of this tumor.

Clinical Relevance

Bladder colonic type adenocarcinoma is a rare entity, accounting for less than 2% of all bladder tumors. It tends to present at an advanced stage, which contributes to its poor prognosis [2][8]. The clinical relevance of this cancer lies in its potential to mimic other types of bladder cancers, making differential diagnosis challenging.

Differential Diagnosis

The differential diagnosis of bladder colonic type adenocarcinoma includes other rare forms of bladder cancer, such as mucinous and clear cell adenocarcinomas. It is essential to consider the morphological characteristics and clinical presentation when differentiating these entities [6][9].

Symptoms of Bladder Colonic Type Adenocarcinoma

Bladder colonic type adenocarcinoma is a rare and aggressive form of bladder cancer that shares similarities with colon cancer. The symptoms can be mistaken for those of a urinary tract infection (UTI) or bladder stones, making it essential to seek medical attention if you experience any unusual signs.

Common Symptoms:

• Blood in urine (hematuria), which may appear as bright red or cola-colored urine [1]
• Abdominal pain or discomfort, similar to that experienced with colon cancer [10]
• Changes in bowel habits, such as diarrhea or constipation, due to the proximity of the bladder and colon [5]
• Ongoing discomfort or feeling full, possibly related to the tumor's growth [5]

Less Common Symptoms:

• Problems emptying the bladder
• A burning sensation while urinating
• Frequent urination needs
• Pain while urinating

It is crucial to note that these symptoms can be similar to those experienced with other conditions, such as UTIs or bladder stones. However, if you experience any of these signs, it is essential to consult a healthcare provider for proper evaluation and treatment.

Early Detection

When caught in its early stages, bladder cancer can be highly treatable. Knowing the signs and symptoms of bladder colonic type adenocarcinoma can help with early detection and improve treatment outcomes [14].

Diagnostic Tests for Bladder Colonic Type Adenocarcinoma

Bladder colonic type adenocarcinoma is a rare and aggressive form of cancer that can occur in the bladder. Diagnosing this condition requires a combination of imaging tests, urine analysis, and biopsy.

• Imaging Tests: The following imaging tests may be used to diagnose bladder colonic type adenocarcinoma:
  • Ultrasound: This test uses high-frequency sound waves to create images of the inside of the body. It can help identify tumors in the bladder [7].
  • CT scan: A computed tomography (CT) scan is a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements taken from different angles to produce cross-sectional images of the body. It can help identify tumors in the bladder and surrounding tissues [7].
  • MRI scan: Magnetic resonance imaging (MRI) is a non-invasive test that uses magnetic fields and radio waves to create detailed images of the inside of the body. It can help identify tumors in the bladder and surrounding tissues [7].
• Urine Tests: Urine tests may be used to diagnose bladder colonic type adenocarcinoma by detecting abnormal cells or proteins in the urine.
  • Urine cytology: This test involves examining a sample of urine under a microscope for abnormal cells. It can help identify cancerous cells in the bladder [8].
• Biopsy: A biopsy is a procedure where a small sample of tissue is removed from the bladder and examined under a microscope for cancerous cells.
  • Cystoscopy: This test involves using a cystoscope (a pencil-sized lighted tube) to examine the inside of the bladder. It can help identify tumors in the bladder [4].
  • Transurethral resection of bladder tumour (TURBT): This procedure involves removing a tumor from the bladder using a cystoscope and examining it under a microscope for cancerous cells [7].

Immunohistochemical Staining: Immunohistochemical staining may also be used to help distinguish between bladder colonic type adenocarcinoma and other types of tumors. For example, primary bladder adenocarcinoma is usually positive for CK7 and thrombomodulin, while colorectal origin tumors are often positive for β-catenin and CK20 [2].

Treatment Options for Bladder Adenocarcinoma

Bladder adenocarcinoma, a rare type of cancer that originates in the urinary bladder, can be challenging to treat. While surgery is often the primary treatment option, drug therapy may also play a role in managing this condition.

• Chemotherapy: Chemotherapy is one potential treatment option for bladder adenocarcinoma. According to [5], cisplatin is a common chemotherapeutic drug used in treating bladder cancer.
• Targeted Therapy: Targeted therapy, which involves using medications to specifically target cancer cells, may also be an option for some patients with bladder adenocarcinoma. However, the effectiveness of targeted therapy in this context is still being researched and debated [9].
• Immunotherapy: Immunotherapy, which harnesses the power of the immune system to fight cancer, has shown promise in treating various types of cancer, including bladder cancer. However, its role in treating bladder adenocarcinoma specifically requires further investigation.

It's essential to note that treatment options for bladder adenocarcinoma can vary depending on the stage and severity of the disease, as well as individual patient factors. A comprehensive discussion with a healthcare provider is necessary to determine the most effective course of treatment.

Differential Diagnosis of Bladder Colonic Type Adenocarcinoma

Bladder colonic type adenocarcinoma is a rare and challenging tumor to diagnose, as it can be easily confused with other types of cancer. The differential diagnosis for bladder colonic type adenocarcinoma includes:

• Metastatic colonic adenocarcinoma: This is the most common differential diagnosis for bladder colonic type adenocarcinoma. Metastatic colonic adenocarcinoma occurs when cancer cells from the colon spread to the bladder.
• Urachal carcinoma: Urachal carcinoma is a rare tumor that can present as a bladder mass and should be considered in the list of differential diagnoses for bladder colonic type adenocarcinoma.
• Primary enteric-type adenocarcinoma of the urinary tract: This is another type of cancer that can be confused with bladder colonic type adenocarcinoma. It is a rare tumor that arises from the epithelium of the urinary tract.
• Urothelial carcinoma with glandular differentiation: Urothelial carcinoma is a common type of bladder cancer, and when it has glandular differentiation, it can be confused with bladder colonic type adenocarcinoma.

Diagnostic Challenges

The diagnosis of bladder colonic type adenocarcinoma can be challenging due to its rarity and the similarity in appearance to other types of cancer. A panel of immunostains, including CK7, CK20, TM, and beta-catenin, has been shown to be of diagnostic value in differentiating primary bladder adenocarcinoma from secondary adenocarcinoma of colorectal origin [1, 2].

[1] Primary bladder adenocarcinoma usually lacks GATA3 staining, rendering this stain useless in differential diagnosis from secondary colorectal adenocarcinoma. A panel consisting of CK7, CK20, β-catenin and thrombomodulin has some value in differentiating primary bladder adenocarcinoma from metastatic colorectal adenocarcinoma [6].

[2] In addition, our data demonstrate that a panel of immunostains, including CK7, CK20, TM, and beta-catenin, is of diagnostic value in differentiating primary bladder adenocarcinoma from secondary adenocarcinoma of colorectal origin.
