Transitional Cell Carcinoma: Symptoms Diagnosis And Treatment

Bladder Cancer Urothelial Carcinoma

Transitional cell carcinoma is a cancerous tumor most commonly found in the urinary bladder and the urethra.

It is most often seen in older small breed dogs such as Scottish terriers, West Highland white terriers, dachshunds, and Shetland sheepdogs and rarely identified in cats.

There appears be a genetic component to the development of TCC, especially in Scottish terriers. Rare cases have been linked with the use of cyclophosphamide and chronic exposure to hydrocarbons. Many times a cause is not determined.

Risk Factors For Bladder Cancer

Cigarette smoking predisposes people to bladder cancer. Smoking cigarettes increases a persons risk of developing bladder cancer approximately 5 fold. Industrial exposure to certain chemicals such as analine in the dye industry increases the risk. Other organic chemicals used in rubber and other manufacturing processes can also increase the risk. Exposure to the chemotherapy agent Cyclophosphamide is associated with a higher risk of developing bladder cancer. Chronic irritation of the bladder appears to provoke development of bladder cancer. The bladder can be irritated by reoccurring infections and bladder stones. In certain parts of Africa and in the Mediterranean area, a parasitic infection called schistosomiasis causes irritation of the lining of the bladder. The parasites that burrow into the bladder appear to stimulate the tumour.

Types Of Bladder Cancer

Bladder cancer can be described based on where it is found:

  • non-muscle invasive the cancer has not spread to other layers of the bladder or muscle
  • muscle-invasive the cancer has spread to other layers of the bladder, muscle or other parts of the body.

There are 3 main types of bladder cancer:

  • urothelial carcinoma 80 to 90% of bladder cancers sometimes called transitional cell carcinoma
  • squamous cell carcinoma 1 to 2% of all bladder cancers. It is more likely to be invasive
  • adenocarcinoma 1 to 2% of all bladder cancers. It is more likely to be invasive .

There are other, less common types of bladder cancer. Treatment for these may be different. Speak to your doctor or nurse for information about these types of cancer.

Demographics And Clinical Features

From March 1999 to January 2014, a total of 38 patients with SCCB were treated at FCCC. Median age was 68 years, 28 out of 38 patients were male. 22 patients were current smokers, 6 patients had previous smoking history. There was one patient of Indian descent, rest of the patients were Caucasian. Staging computerized tomography was done in all cases. 22 patients had stage 2 disease at the time of diagnosis. 7 patients had stage 4 disease. 36.8% of the patients had mixed small cell and urothelial cell carcinoma based on the pathology report. Most common presenting symptom was hematuria, most common sites of metastases were liver, bone and lung. Rest of the patient and disease characteristics are summarized in .

Significance Of Hub Genes In The Prognosis Of Patients With Bladder Transitional Cell Carcinoma

Overall survival of the hub genes in bladder cancer with human ...

By screening the subnetworks, the MCODE score of each gene in the subnetworks was obtained. In order to further explore their ability in predicting prognosis, a total of 33 hub genes including the top 30 genes of MCODE score in Module 1 and seed genes in Module 2 and Module 3 were selected for subsequent analysis. In TCGA-BLCA data set, the median of gene expression in all tumor samples was used as the cutoff value for grouping. The results of KaplanMeier survival analysis exhibited that the OS rate and PFS rate of patients with high expression of Cyclin B1 and Actin Alpha Cardiac Muscle 1 were remarkably lower . Furthermore, patients with high expression of Assembly Factor for Spindle Microtubules had a dramatically lower PFS rate , but there was no significant difference in OS . Overall, the three hub genes including CCNB1, ASPM, and ACTC1 had good prognostic value in BTCC.

What Is A 5

A relative survival rate compares people with the same type and stage of bladder cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of bladder cancer is 90%, it means that people who have that cancer are, on average, about 90% as likely as people who dont have that cancer to live for at least 5 years after being diagnosed.

  • When stratified by age, the 5-year relative survival of patients with bladder cancer was 83.8% and 74.1% for patients < 65 and 65 years of age respectively.
  • The survival of patients with bladder cancer varies with the stage of the disease. Shown below is a table depicting the 5-year relative survival by the stage of bladder cancer:

What Should You Do After Receiving A Squamous Cell Carcinoma Diagnosis

After being diagnosed with squamous cell carcinoma, its important to act quickly, since treating this malignancy early can increase the chances of survival. One of the first things you should do is choose a cancer specialistsuch as the ones at Moffitt Cancer Centerwho can stage the cancer, tell you more about your condition and the treatment options available to you and answer any questions you might have.

Squamous cell carcinoma can be treated using a variety of different methods, and a cancer expert can recommend the one thats best suited to your specific needs . Some potential treatment options include:

  • Mohs surgery, which involves removing and examining thin layers of tissue until no more cancerous cells are found. Mohs surgery is offered in conjunction with the USF Department of Dermatology
  • Excisional surgery, which involves removing a cancerous lesion and a portion of the surrounding healthy tissue, then examining it to confirm that the cancerous cells have all been removed
  • Electrosurgery, which involves scraping away a lesion using a curette and then heating the area with an electrocautery needle in order to destroy any remaining cancerous cells and control bleeding

What Causes Transitional Cell Carcinoma

Bladder Cancer for USMLE Step 2

Researchers are still unsure about the exact cause of transitional cell carcinoma. There may be a connection between smoking, infection, exposure to chemicals, and exposure to radiation. The actual cancer starts when the cell in the urinary tract begin to change and grow more rapidly than usual. The cells do not shed, but continue to grow into tumors.

Transitional cell carcinoma happens in the inside lining of the bladder, the urethra, and ureters. The cells mimic regular cells and open up when the bladder is full and squeeze back together when there is nothing in the bladder.

There are a few risk factors that raise the chances of TCC including:

Symptoms In Men And Women

Bladder cancer symptoms in men and women are the same. Men are more likely to get bladder cancer, but they are also more likely to have it diagnosed earlier, according to Moffitt Cancer Center.

Women are more likely to mistake bladder cancer symptoms for urinary tract infections or menstruation.

Rarely, bladder cancer may also be misdiagnosed as interstitial cystitis in women. IC is a painful, inflammatory bladder condition that affects more women than men.

In one study, doctors found bladder cancer in about one percent out of 600 patients referred to them for IC treatment, according to an article in Urology Times.

Bladder Cancer Treatment: Surgery

Transurethral Resection

Early-stage cancers are most commonly treated by transurethral surgery. An instrument with a small wire loop is inserted through the urethra and into the bladder. The loop removes a tumor by cutting or burning it with electrical current, allowing it to be extracted from the bladder.

Partial and Radical Cystectomy

Partial cystectomy includes the removal of part of the bladder. This operation is usually for low-grade tumors that have invaded the bladder wall but are limited to a small area of the bladder. In a radical cystectomy, the entire bladder is removed, as well as its surrounding lymph nodes and other areas that contain cancerous cells. If the cancer has metastasized outside of the bladder and into neighboring tissue, other organs may also be removed such as the uterus and ovaries in women and the prostate in men.

What Is The Outlook For This Type Of Cancer

The outlook for someone diagnosed with cancer of the renal pelvis and ureter depends on a number of factors that your doctor will discuss with you. In particular, the chance of recovery is dependent on:

  • Stage of the cancer. People with advanced stages of the disease will have a lower survival rate, even with treatment.
  • Location of the tumor. If the tumor is located beyond the ureter and renal pelvis, the cancer may quickly metastasize to the kidney or other organs, reducing chances for survival.
  • Overall kidney health. If there are underlying kidney disorders, the survival rate is lower, even with treatment.
  • Cancer recurrence. Cancer recurrences have lower cure and survival rates than initial cancers.
  • Metastasis. If the cancer has spread to other organs in the body, the survival rate is lower.

Its important to see your doctor for regular checkups and to let them know about any new symptoms youve developed. This helps your doctor catch potentially serious conditions in the earliest stages.

Screening Prognostic Factors For Renal Pelvic Tcc Patients

Radiotherapy may improve overall survival of patients with T3/T4 ...

The univariate Cox proportional hazards regression was used to screen prognostic factors, and the results showed that age, tumor size, grade, histologic type, AJCC TNM stage, surgery, radiotherapy, chemotherapy, bone metastasis, brain metastasis, liver metastasis and lung metastasis were OS- and CSS-related factors . Then, all OS- or CSS-related factors were incorporated into the multivariate Cox analysis, and age, tumor size, histologic type, AJCC stage, surgery, chemotherapy, bone metastasis and liver metastasis were determined as independent OS- and CSS-related factors .

Signs And Symptoms Of Transitional Cell Cancer Of The Renal Pelvis And Ureter Include Blood In The Urine And Back Pain

These and other signs and symptoms may be caused by transitional cell cancer of the renal pelvis and ureter or by other conditions. There may be no signs or symptoms in the early stages. Signs and symptoms may appear as the tumor grows. Check with your doctor if you have any of the following:

  • Blood in the urine.
  • Weight loss with no known reason.
  • Painful or frequent urination.

Latest Treatment For Bladder Cancer

Intravesical therapy is a newer treatment for people who have bladder cancer. With intravesical therapy, the doctor puts a liquid medication right into your bladder rather than administering it orally or injecting it into your blood. The medication is put in through a catheter thats placed into your bladder through the urethra. The medication stays in your bladder for up to two hours, so it can affect the cells lining the inside of the bladder without having major effects on other parts of your body. Intravesical therapy is commonly used after transurethral resection of bladder tumor . Its often performed within 24 hours of the TURBT procedure. The goal is to kill any cancer cells that may be left in the bladder.

Intravesical chemotherapy is used to treat non-invasive bladder cancer. It is used for these early-stage cancers because medication given this way mostly affects the cells lining the inside of the bladder. It has little to no effect on cells elsewhere. This means any cancer cells outside of the bladder lining are not treated by intravesical chemotherapy.

Transitional Cell Carcinoma Of Upper Urinary Tract

Transitional Cell Carcinoma in Dogs (TCC)
  • Depending on the stage and grade of the tumor at the time of diagnosis, the prognosis may vary. However, the 5-year survival rate of patients with upper urinary tract transitional cell carcinoma is approximately 75%.
  • The major prognostic factor at the time of diagnosis of upper tract transitional cell cancer is the depth of infiltration into or through the uroepithelial wall.
  • Most superficial tumors are likely to be well-differentiated, while infiltrative tumors are likely to be poorly differentiated.
  • They are curable in more than 90% of patients if they are superficial and confined to the renal pelvis or ureter.
  • Patients with deeply invasive tumors that are still confined to the renal pelvis or ureter have a 10% to 15% likelihood of cure.
  • Patients with tumors with penetration through the urothelial wall or with distant metastases usually cannot be cured with currently available forms of treatment.
  • When involvement of the upper urinary tract is diffuse , the likelihood of subsequent development of bladder cancer increases to 75%.
  • DNA ploidy has not added significant prognostic information beyond that provided by stage and grade.

Urothelial Carcinoma The Most Common Form Of Bladder Cancer Linked To Smoking

Doru Paul, MD, is triple board-certified in medical oncology, hematology, and internal medicine. He is an associate professor of clinical medicine at Weill Cornell Medical College and attending physician in the Department of Hematology and Oncology at the New York Presbyterian Weill Cornell Medical Center.

While bladder cancer may not be as frequently spotlighted as other types of cancer like melanoma, lung cancer, or breast cancer, it’s the fourth most common cancer in American men and the ninth most common in American women. According to data from the Centers for Disease Control and Prevention, over 55,000 men and 17,000 women get bladder cancer in the U.S. every year. Of these, nearly 16,000over one in fourwill die as a result of a malignancy.

The most common type of bladder cancer is called transitional cell carcinoma . Also known as urothelial carcinoma , TCC arises from the inner lining of the urinary tract called, aptly, the transitional urothelium.

TCC can develop in tissue from anywhere along the tract, including:

  • The renal sinus
  • The ureter
  • The innermost lining of the bladder
  • The urethra
  • The urachus

TCC is considered the second most common cause of kidney cancer when involving the renal sinus.

How Is Transitional Cell Carcinoma Of The Prostate Diagnosed

This disease is hard to diagnose. Itâs often mistaken for something else at first. Thatâs partly why itâs hard to treat successfully. By the time itâs caught, itâs usually already advanced.

The symptoms are the same as for other kinds of prostate problems. You may have:

  • A hard time peeing
  • Pain or irritation when you pee
  • Blood in your urine

The level of prostate specific antigen in your blood, which is often an early clue you have prostate cancer, may not be high when you have this kind. Cancerous urothelial cells donât make PSA.

Your prostate will feel hard or lumpy in a digital rectal exam, but that isnât usually how itâs diagnosed.

Most men find out they have transitional cell carcinoma of the prostate after theyâve had a transurethral resection of the prostate. Thatâs a procedure to treat urinary problems caused when your prostate becomes enlarged.

A surgeon inserts an instrument into the urethra through the end of the penis. With either an electric current or laser, they cut away pieces of prostate tissue. When they look at that tissue under a microscope, they can spot cancerous urothelial cells.
