Signs and symptoms of bladder cancer

• Blood in the urine (slightly rusty to bright red in color).

• Frequent urination.• Pain during urination.• Lower back pain.

Risk Factors for Bladder Cancer

• Using tobacco, especially smoking cigarettes.• Having a family history of bladder cancer.• Being exposed to certain chemicals in the

workplace.• Past treatment with certain anticancer drugs,

such as cyclophosphamide or ifosfamide, or radiation therapy to the pelvis.

• Drinking well water that has high levels of arsenic.

• Having a history of bladder infections, including bladder infections caused by Schistosoma haematobium.

• Using urinary catheters for a long time.

Diagnosing Bladder Cancer

Diagnosing Bladder Cancer

Usually a cystoscopy and biopsy will be done. There are 3 types of cancer but most people will have transitional cell (or urothelial cancer)

This starts in the lining of the bladder and the outlook or prognosis is based on whether the cancer has started to invade the wall of the bladder or the grade (how mutated the cells have become)

Histology

• Urothelial Cancer > 90% (>90% are in bladder, 8% in renal pelvis, 2% in ureter or urethra)

• Squamous Cancer – 3%• Adenocarcinoma – 1.4%• Small Cell – 1%

Understanding the Pathology Report

1.Type of cancer (urothelial or papillary)2. Invasive or non-invasive3.Grade (how mutated are the cells)4.Biopsy (how deep) to determine the stage.

This information plus imaging studies will determine the clinical stage

5.Final pathology report after major surgery will determine the pathologic stage

Stages of Bladder Cancer

Basically how deep has the cancer invaded into the wall of the bladder and has it spread elsewhere to other organs or lymph nodes

T Stage…how deep into the wall of the bladder the cancer has invaded

Layers of the Bladder Wall

ureter

urothelium

lamina propria

muscle

fat

peritoneum

Bladder wall

Urothelium or Transitional cell layer

Lamina propria or Connective tissue

Muscle layer

Fat layer

Layers of the Bladder Wall

1. Epithelium2. Subepithelial Connective Tissue3. Muscle4. Perivesical Fat

Invades local organs

Invades pelvic or abdominal wall

Stage 0 (Papillary Carcinoma and Carcinoma in Situ)

Abnormal cells are found in the tissue lining the inside of the bladder

Stage I Bladder Cancer

Cancer has spread to the layer of connective tissue next to the inner lining of the bladder.

Risk of a relapse is related to how deep the cancer invade and how mutated the cancer cells are. Low grade (slow growing) or High grade (more mutated, more fast growing)

Stage II Bladder Cancer

Cancer has spread to the layers of muscle tissue of the bladder.

Stage III Bladder Cancer

Cancer has spread from the bladder to the layer of fat surrounding it. It may also have spread to the prostate and/or seminal vesicles in men or the uterus and/or vagina in women.

Stage IV Bladder Cancer

Cancer has spread from the bladder to (a) the wall of the abdomen or pelvis, (b) one or more lymph nodes, and/or (c) other parts of the body, such as the lung, liver, or bone.
