TREATMENTS
The majority of bladder
cancers arise from the lining of the bladder. Over 75
percent of these tumors remain confined to the linin
layer and do not invade into the bladder wall. These
tummors are called superficial transitional
cell cancers. Advanced bladder cancer is cancer
which has invaded into the bladder wall or outside the
bladder. Advanced cancer treatment options are different
than those for superficial bladder cancer.
Bladder cancer treatment
is determined due to the stage and grade of the tumor(s).
TREATMENT
FOR SUPERFICIAL BLADDER CANCER CAN INCLUDE:
- Cystoscopy with cautery
destruction of the tumor
- Most modern cystoscopes are equipped
with channels that permit small instruments to be passed
into the bladder for the purpose of removing tissue, stopping
bleeding with a special electrical device called an electrocautery
or even performing laser treatment. If the bladder cancer
tumor is small enough this cautery may be used to remove
cancer.
- TUR(Trans-Urethral
Resection)
- This is when the tumor is removed via electrical
force from the urinary tract through the urethra.
TUR is an endoscopic or scope procedure that does
not involve making an incision in the body. The entire
removal of the bladder tumor can be accomplished
through an operative scope which is passed through
the urethra into the bladder.
- Drug therapy after TUR is commonly prescribed for
patients with tumors that are large, multiple or
high grade.
- Intravesical drug therapy
/Immunotherapy
- Here medicines are placed directly into the bladder
(intravesical) via a urethral catheter in order to
lower the recurrence rate of bladder tumors. This
is usually used for multiple CIS large in size (5
cm plus), high grade in stage tumors. About 50-68%
of patients with superficial bladder cancer have
a very good response to intravesical therapy.
- Commonly used intravesical drugs are:
- Mitomycin C which kills
the normal DNA function in cancer cells and
is easily absorbed into the bloodstream through
the bladder's lining
- Bacille Calmette-Guerin (BCG) forces
the immune system to respond to the BCG drug
in the lining of the bladder, thus forcing the
body's immune system to help fight off the cancer
TREATMENT FOR ADVANCED
BLADDER CANCER
- Partial or radical
(complete) cystectomy surgery
- This is performed when tumors completely invade the bladder's
muscular wall
- Partial bladder removal is rare because the requirements
are that all the tumor(s) are easily accessible to be removed,
small in size and there are no tumor(s) in the rest of the
bladder. This is usually used only if the cancer has not left
its' site of origin. Additionally, if all other treatments
fail for superficial cancer, this could be used as an alternative.
- Radiation Therapy
- The type of radiation which is used to treat
cancer is actually a special high energy x-ray
that is more powerful than x-rays used for imaging
studies. Radiation therapy is planned and executed
in a way to kill cancer cells or alter their
ability to reproduce while the surrounding healthy
cells are minimally effected . Historically,
radiation therapy has been used for muscle invasive
bladder cancer but current treatment can involve
a combined approach of both radiation and chemotherapy.
The role of radiation therapy in combination
with chemoradiaton therapy (combined chemotherapy
and radiation therapy) is to kill the bladder
cancer cells both in the bladder and outside
the bladder. Local lymph nodes are frequently
radiated as part of the therapy to treat the
microscopic cancer cells which may be in the
nodes.
- Chemotherapy
- Chemotherapy is the use of chemical agents
that interfere with the replication and other
normal functions of cells and results in tumor
shrinkage or cancer cell death. The use of two
or more chemotherapy drugs together has been
found to be more effective than a single drug
alone. There are several types of chemotherapy
which can be used. The most common chemotherapeutic
drug used in bladder cancer is cisplatin.
