The type of treatment(s) your doctor recommends will depend on
the stage of the cancer and on your overall health. This section
summarizes options usually considered for each stage of kidney cancer.
Stages I, II, or III
These cancers are usually removed surgically when possible.
Radical nephrectomy is usually the operation of choice. If you have a
smaller stage I tumor, have only one good kidney, have cancer in both
kidneys, or have an inherited condition like von Hippel-Lindau (VHL)
disease, a partial nephrectomy may be an option. For larger or more
extensive tumors, radical nephrectomy is more likely than partial
nephrectomy to be curative. Some patients may have an arterial
embolization before surgery to reduce the amount of bleeding during
nephrectomy. Lymph nodes around the kidneys may be removed as well. If
the cancer has grown into nearby veins (as with some stage III
cancers), the surgeon may cut open these veins, remove the cancer, and
repair the vein.
Other than as part of a clinical trial, adjuvant
(additional) treatments such as targeted therapy, chemotherapy,
radiation therapy, or immunotherapy are usually not recommended after
surgery, as the benefit of additional therapy has not been proven.
There are, however, ongoing clinical trials that are looking at
adjuvant treatment for kidney cancer. Ask your doctor for more
information about adjuvant clinical trials.
If you cannot have kidney surgery because of other serious
medical problems, you may benefit from other local treatments such as
cryotherapy, radiofrequency ablation, radiation therapy, or arterial
embolization. Although the long-term effectiveness of these methods has
not been thoroughly studied yet, they are considered to be less effective
than surgery.
Stage IV
Treatment of stage IV kidney cancer depends on how extensive
the cancer is and on the person's general health. In some cases,
surgery may still be a part of treatment.
In rare cases where the main tumor appears to be removable and
the cancer has only spread to one other area (such as to one or a few
spots in the lungs), surgery to remove both the kidney and the
metastasis may be an option if a person is in good enough health.
Otherwise, treatment with one of the targeted therapies would probably
be the first option.
If the main tumor is removable but the cancer has spread
extensively elsewhere, removing the kidney may still be helpful. This
would likely be followed by systemic therapy, which might consist of
one of the targeted therapies or cytokine therapy (interleukin-2 or
interferon). More often targeted therapy is used first. It's not clear
if any one of the targeted therapies or any particular sequence is
better than another, although temsirolimus appears to be most useful in
people with kidney cancers that have a poorer prognosis.
For cancers that can't be removed surgically (because of the
extent of the tumor or a person's health), first-line treatment would
likely be one of the targeted therapies or cytokine therapy.
Because advanced kidney cancer is very hard to cure, clinical
trials of new combinations of targeted therapies, immunotherapy, or
other new treatments are also options.
For some patients, palliative treatments such as embolization
or radiation therapy may be the best option. A special form of
radiation therapy called stereotactic radiosurgery can be very
effective in treating single brain metastases. Surgery or radiation
therapy can also be used to help reduce pain or other symptoms of
metastases in some other places, such as the bones.
Having your pain controlled appropriately can help you
maintain your quality of life. It is important to realize that
medicines to relieve pain do not interfere with your other treatments
and that controlling pain will often help you be more active and
continue your daily activities.
Cancer that progresses or recurs (comes
back) after treatment
Treatment of kidney cancer that comes back (recurs) after
initial treatment or does not respond to the initial treatment
(refractory cancer) depends on where it recurs and what treatments have
been used, as well as a person's health and wishes for further
treatment.
For cancers that recur after initial surgery, further surgery
might be an option in some cases. Otherwise, treatment with targeted
therapies or immunotherapy will probably be recommended. Clinical
trials of new treatments are an option as well.
For cancers that progress (continue to grow or spread) during
treatment with targeted therapy or cytokine therapy, another type of
targeted therapy may be helpful, at least for a time. If these don't
work chemotherapy may be tried, especially in people with non-clear
cell types of kidney cancer. Clinical trials may be a good option in
this situation for those who want to continue treatment.
Again, for some patients, palliative treatments such as
embolization or radiation therapy may be the best option. Controlling
symptoms such as pain is an important part of treatment at any stage of
the disease.
