Prognosis: Disease Course Often Hard To Predict
In the United States, improved cancer screening and treatment have reduced the number of people who die from certain cancers, such as colon cancer. However, your chances of survival are generally decreased if a cancer has spread beyond its primary location.
Malignant tumors can vary in their aggressiveness, so it is difficult to predict how rapidly they will grow. A medical oncologist can recommend appropriate testing and treatment to give you the best chance of survival.
Genetic Factors In Pathogenesis
Divergent, yet interconnected and overlapping, molecular pathways are likely responsible for the development of noninvasive and invasive bladder tumors. Somatic mutations in fibroblast growth receptor3 and tumor protein p53 in tumor cells appear to be important early molecular events in the noninvasive and invasive pathways, respectively.
FGFR-3, Ras, and PIK3CA mutations occur with high frequency in noninvasive tumors, leading to upregulation of Akt and mitogen-activated protein kinase . Loss of heterozygosity on chromosome 9 is among the most frequent genetic alterations in bladder tumors and is considered an early event.
Large numbers of genomic changes have been detected using karyotyping and comparative genomic hybridization analysis in urothelial carcinoma. Numerically common are losses of 2q, 5q, 8p, 9p, 10q, 18q, and Y. Gains of 1q, 5p, 8q, and 17q are frequently present, and high-level amplifications can be found however, the target genes in the regions of amplifications have not been conclusively identified.
Alterations in the TP53 gene are noted in approximately 60% of invasive bladder cancers. Progression-free survival is significantly shorter in patients with TP53 mutations and is an independent predictor of death among patients with muscle-invasive bladder cancer.
What Is Muscle Invasive Bladder Cancer
Muscle invasive bladder cancer is a cancer that spreads into the detrusor muscle of the bladder. The detrusor muscle is the thick muscle deep in the bladder wall. This cancer is more likely to spread to other parts of the body.
In the U.S., bladder cancer is the third most common cancer in men. Each year, there are more than 83,000 new cases diagnosed in men and women. About 25% of bladder cancers are MIBC. Bladder cancer is more common as a person grows older. It is found most often in the age group of 75-84. Caucasians are more likely to get bladder cancer than any other ethnicity. But there are more African-Americans who do not survive the disease.
What is Cancer?
Cancer is when your body cells grow out of control. When this happens, the body cannot work the way it should. Most cancers form a lump called a tumor or a growth. Some cancers grow and spread fast. Others grow more slowly. Not all lumps are cancers. Cancerous lumps are sometimes called malignant tumors.
What is Bladder Cancer?
When cells of the bladder grow abnormally, they can become bladder cancer. A person with bladder cancer will have one or more tumors in his/her bladder.
How Does Bladder Cancer Develop and Spread?
The bladder wall has many layers, made up of different types of cells. Most bladder cancers start in the urothelium or transitional epithelium. This is the inside lining of the bladder. Transitional cell carcinoma is cancer that forms in the cells of the urothelium.

Other Types Of Bladder Cancer
Approximately 2% of bladder cancers are adenocarcinomas. Nonurothelial primary bladder tumors are extremely rare and may include small cell carcinoma, carcinosarcoma, primary lymphoma, and sarcoma . Small cell carcinoma of the urinary bladder accounts for only 0.3-0.7% of all bladder tumors. High-grade urothelial carcinomas can also show divergent histologic differentiation, such as squamous, glandular, neuroendocrine, and sarcomatous features.
Rare Forms Of Bladder Cancer
Adenocarcinomas account for less than 2% of primary bladder tumors. These lesions are observed most commonly in exstrophic bladders and are often associated with malignant degeneration of a persistent urachal remnant.
Other rare forms of bladder cancer include leiomyosarcoma, rhabdosarcoma, carcinosarcoma, lymphoma, and small cell carcinoma. Leiomyosarcoma is the most common sarcoma of the bladder. Rhabdomyosarcomas most commonly occur in children. Carcinosarcomas are highly malignant tumors that contain a combination of mesenchymal and epithelial elements. Primary bladder lymphomas arise in the submucosa of the bladder. Except for lymphomas, all these rare bladder cancers carry a poor prognosis.
Small cell carcinoma of the urinary bladder is a poorly differentiated, malignant neoplasm that originates from urothelial stem cells and has variable expression of neuroendocrine markers. Morphologically, it shares features of small cell carcinoma of other organs, including the lung.

What Is A Malignant Neoplasm
If your doctor says you have a malignant neoplasm, you may be wondering what that is and what to do next.
The term “malignant neoplasm” means that a tumor is cancerous. A doctor may suspect this diagnosis based on observation such as during a colonoscopy but usually a biopsy of the lesion or mass is needed to tell for sure whether it is malignant or benign .
Prognosis In Squamous Cell Carcinoma
Tumor stage, lymph node involvement, and tumor grade have been shown to be of independent prognostic value in SCC. However, pathologic stage is the most important prognostic factor. In one relatively large series of 154 cases, the overall 5-year survival rate was 56% for pT1 and 68% for pT2 tumors. However, the 5-year survival rate for pT3 and pT4 tumors was only 19%.
Several studies have demonstrated grading to be a significant morphologic parameter in SCC. In one series, 5-year survival rates for grade 1, 2, and 3 SCC was 62%, 52%, and 35%, respectively. In the same study of patients undergoing cystectomy, the investigators suggested that a higher number of newly formed blood vessels predicts unfavorable disease outcome.
In SCC, the survival rate appears to be better with radical surgery than with radiation therapy and/or chemotherapy. In locally advanced tumors, however, neoadjuvant radiation improves the outcome. Sex and age have not been prognostically significant in SCC.

What about Clinical Trials?
You may hear about clinical trials for your bladder cancer. Clinical trials are research studies that test if a new treatment or procedure is safe and effective.
Through clinical trials, doctors find new ways to improve treatments and the quality of life for people with disease. Trials are available for all stages of cancer. The results of a clinical trial can make a major difference to patients and their families. Please visit our clinical trials research webpage to learn more.
The Icd Code C67 Is Used To Code Bladder Cancer
Bladder cancer is any of several types of cancer arising from the epithelial lining of the urinary bladder. Rarely the bladder is involved by non-epithelial cancers, such as lymphoma or sarcoma, but these are not ordinarily included in the colloquial term “bladder cancer.” It is a disease in which abnormal cells multiply without control in the bladder.

Occurrence In The United States
The American Cancer Society estimates that 83,730 new cases of bladder cancer will be diagnosed in the United States in 2021 and that 17,200 people will die of the disease. The incidence of bladder cancer increases with age, with the median age at diagnosis being 73 years bladder cancer is rarely diagnosed before age 40 years.
Bladder cancer is about 3 times more common in men than in women. Over the past 2 decades, however, the rate of bladder cancer has been stable in men but has increased in women by 0.2% annually. The male predominance in bladder cancer in the United States reflects the prevalence of transitional cell carcinoma . With small cell carcinomain contrast to TCCthe male-to-female incidence ratio is 1:2.
Bladder cancer is the fourth most common cancer in men in the United States, after prostate, lung, and colorectal cancer, but it is not among the top 10 cancers in women. Accordingly, more men than women are expected to die of bladder cancer in 2021, with 12,260 deaths in men versus 4940 in women. Nevertheless, women generally have a worse prognosis than men.
The incidence of bladder cancer is twice as high in white men as in black men in the United States. However, blacks have a worse prognosis than whites.
Limited data indicate that small cell carcinoma of the urinary bladder probably has the same epidemiologic characteristics as urothelial carcinoma. Patients are more likely to be male and older than 50 years.

Therapy: Treatment Options For Cancer Vary
Treatment options depend on the stage of the cancer and may include surgery, chemotherapy, or radiation.
Surgery may involve removing a small tumor or polyp only, or removing a tumor and a portion of the surrounding tissue, if the tumor is larger or has spread into nearby tissue. The surgeon may also remove some lymph nodes near the area of cancer if its known the cancer has spread to them, or to see if the cancer has spread to them.
Chemotherapy drug therapy may be used before surgery to shrink the size of tumors, or after surgery to kill any remaining cancer cells that may have spread to other parts of the body.
Radiation therapy may similarly be given to shrink tumors before surgery or to kill any remaining cancer cells after surgery. It may also be used in place of surgery in some cases.

What Is A Bladder Neoplasm
A bladder neoplasm is a tumor which develops in the bladder. Although it is an abnormal growth, a bladder neoplasm is not always cancer. Neoplasia, or new growth, can also take the form of a benign tumor, which is not cancerous. In the bladder, benign tumors are found less often than malignant tumors. A malignant tumor usually arises from the lining of the bladder, known as the urothelium.
Benign bladder tumors are quite rare. The two main types of benign neoplasm are known as transitional cell papilloma and nephrogenic adenoma. Sometimes a benign tumor may not cause any symptoms and it could be discovered during an investigation for another condition. In other cases, patients may discover blood in their urine. There is not usually any pain associated with this.
Malignant neoplasms are relatively common. Worldwide, the most frequently occurring type of bladder cancer is known as squamous cell carcinoma. In developed countries, a type of cancer called transitional cell carcinoma is more commonly found. The symptoms associated with bladder malignancy are similar to those experienced with benign tumors. Blood is seen in the urine, but there is not any pain, as there would be with other disorders such as a urinary tract infection.
Papillary Vs Flat Cancer
Bladder cancers are also divided into 2 subtypes, papillary and flat, based on how they grow .
- Papillary carcinomas grow in slender, finger-like projections from the inner surface of the bladder toward the hollow center. Papillary tumors often grow toward the center of the bladder without growing into the deeper bladder layers. These tumors are called non-invasive papillary cancers. Very low-grade , non-invasive papillary cancer is sometimes called papillary urothelial neoplasm of low-malignant potential and tends to have a very good outcome.
- Flat carcinomas do not grow toward the hollow part of the bladder at all. If a flat tumor is only in the inner layer of bladder cells, it’s known as a non-invasive flat carcinoma or a flat carcinoma in situ .
If either a papillary or flat tumor grows into deeper layers of the bladder, it’s called an invasive urothelial carcinoma.

Start And Spread Of Bladder Cancer
The wall of the bladder has many several layers. Each layer is made up of different kinds of cells .
Most bladder cancers start in the innermost lining of the bladder, which is called the urothelium or transitional epithelium. As the cancer grows into or through the other layers in the bladder wall, it has a higher stage, becomes more advanced, and can be harder to treat.
Over time, the cancer might grow outside the bladder and into nearby structures. It might spread to nearby lymph nodes, or to other parts of the body.
Other Squamous Cell Carcinoma Risk Factors
Having bladder diverticula may increase an individuals chance of developing SCC. Rarely, bacillus Calmette-Guerin treatment for CIS has been reported to lead to development of SCC. Development of bladder cancer at a younger age has been associated with bladder exstrophy. SCC has also been described in urachal remnants.
Coffee consumption does not increase the risk of developing bladder cancer. Early studies of rodents and a minority of human studies suggested a weak connection between artificial sweeteners and bladder cancer however, most recent studies show no significant correlation.

Pathology: Examining Tissue For Signs Of Cancer
When a polyp or other area of suspicious tissue is seen during a cancer screening test, the doctor may take a tissue sample called a biopsy right away, depending on the bodily location being examined, or at a later date, if doing so requires a second procedure. A pathologist then examines the tissue under a microscope to look for cancerous cells.
To better visualize the various parts of the tissue, the pathologist often stains it, sometimes with multiple dyes.
The pathologist looks for abnormalities in the shape and size of cells, shape and size of cell nuclei, and distribution of the cells in the tissue, indicating cancer.
Once the pathologist has confirmed that a biopsy shows cancer, other lab tests may be done to help classify the cancer, which can in turn help to guide treatment.
While much of the work of examining tissue samples is still done by individuals looking through microscopes, advances in automated detection and classification of cancer cells promise faster diagnosis and treatment.

What Is Bladder Cancer
Bladder cancer starts when cells that make up the urinary bladder start to grow out of control. As more cancer cells develop, they can form a tumor and, with time, spread to other parts of the body.
The bladder is a hollow organ in the lower pelvis. It has flexible, muscular walls that can stretch to hold urine and squeeze to send it out of the body. The bladder’s main job is to store urine. Urine is liquid waste made by the 2 kidneys and then carried to the bladder through 2 tubes called ureters. When you urinate, the muscles in the bladder contract, and urine is forced out of the bladder through a tube called the urethra.
