The stage of a cervical cancer is the most important factor in
choosing treatment. However, other factors that affect this decision
include the exact location of the cancer within the cervix, the type of
cancer (squamous cell or adenocarcinoma), your age, your overall
physical condition, and whether you want to have children.
Stage 0 (carcinoma in situ)
Although the staging system classifies carcinoma in situ (CIS)
as the earliest form of cancer, doctors often think of it as a
pre-cancer. That is because the cancer cells in CIS are only in the
surface layer of the cervix -- they have not grown into deeper layers
of cells. Treatment options for squamous cell carcinoma in situ are the
same as for other pre-cancers (dysplasia or cervical intraepithelial
neoplasia [CIN]). Options include cryosurgery, laser surgery, loop
electrosurgical excision procedure (LEEP/LEETZ), and cold knife
conization. For adenocarcinoma in situ, hysterectomy is usually
recommended. For those who wish to have children, treatment with a cone
biopsy may be an option. No cancer cells must be found at the edges of
the cone, and the patient must be closely watched as long as the cervix
remains in place. After the woman has finished having children, a
hysterectomy is recommended.
A simple hysterectomy is also an option for treatment of
squamous cell carcinoma in situ, and may be done if it returns
following other treatments. All cases of CIS can be cured with
appropriate treatment. However, pre-cancerous changes can recur (come
back) in the cervix or vagina, so it is very important for your doctor
to watch you closely. This includes follow-up with regular Pap smears
and in some instances with colposcopy.
Stage IA is divided into stage IA1 and stage
IA2
Stage IA1: For
this stage you have 3 options
- If you still want to be able to have children, first the
cancer is removed with a cone biopsy, and then you are watched closely
to see if the cancer comes back.
- If the cone biopsy doesn't remove all of the cancer (or if
you are done having children), the uterus will be removed
(hysterectomy).
- If the cancer has invaded the blood vessels or lymph
vessels, you might need a radical hysterectomy along with removal of
the pelvic lymph nodes.
Stage IA2:
There are 3 treatment options
- radical hysterectomy along with removal of lymph nodes in
the pelvis
- external beam radiation therapy plus brachytherapy
- radical trachelectomy with removal of pelvic lymph nodes
can be done if you still wants to be able to have children
If you have surgery, the tissue removed will be examined in
the laboratory to see if the cancer has spread further than expected.
If the cancer has spread to the tissues next to the uterus (called the parametria) or to
any lymph nodes, radiation therapy is usually recommended. Often
chemotherapy will be given with the radiation therapy. If the pathology
report says that the tumor had
positive margins, this means that some cancer may have
been left behind. This is also treated with pelvic radiation (given
with cisplatin chemotherapy). The doctor may advise brachytherapy, as
well.
Stage IB is divided into stage IB1 and stage IB2
Stage IB1:
There are 3 options available:
- The standard treatment is a radical hysterectomy with
removal of lymph nodes in the pelvis. Some lymph nodes from higher up
in the abdomen (called para-aortic
lymph nodes) are also removed to see if the cancer has
spread there. If cancer cells are found in the edges of the tissues
removed (positive margins) or if cancer cells are found in lymph nodes
during this operation, radiation therapy may be given, possibly with
chemotherapy, after surgery.
- The second treatment option is high-dose internal and
external radiation therapy.
- Radical trachelectomy with removal of pelvic (and some
para-aortic) lymph nodes is an option if the patient still wants to be
able to have children
Stage IB2: There
are 3 options available
- The standard treatment is the combination of chemotherapy
with cisplatin and radiation therapy to the pelvis plus brachytherapy.
- Another choice is radical hysterectomy with removal of
pelvic (and some para-aortic) lymph nodes. If cancer cells are found in
the lymph nodes removed, or in the margins, radiation therapy may be
given, possibly with chemotherapy, after surgery.
- Some doctors advise radiation given with chemotherapy
(first option) followed by a hysterectomy.
Stage II is divided into stage IIA and stage
IIB
Stage IIA:
Treatment for this stage depends on the size of the tumor.
- One choice for treatment is brachytherapy and external
radiation therapy. This is most often recommended if the tumor is
larger than 4 cm (about 1½ inches). Chemotherapy with
cisplatin will be given along with the radiation.
- Some experts recommend removing the uterus after the
radiation therapy is done.
- If the cancer is not larger than 4 cm, it may be treated
with a radical hysterectomy and removal of lymph nodes in the pelvis
(and some in the para-aortic area). If the tissue removed at surgery
shows cancer cells in the margins or cancer in the lymph nodes,
radiation treatments to the pelvis will be given with chemotherapy.
Brachytherapy may be given as well.
Stage IIB:
Combined internal and external radiation therapy is the usual
treatment. The radiation is given with the chemotherapy drug cisplatin.
Sometimes other chemo drugs may be given along with cisplatin.
Stage III and IVA
Combined internal and external radiation therapy given with
cisplatin is the recommended treatment.
If cancer has spread to the lymph nodes (especially those in
the upper part of the abdomen) it can be a sign that the cancer has
spread to other areas in the body. Some experts recommend checking the
lymph nodes for cancer before giving radiation. One way to do this is
by surgery. Another way is to do a CT or MRI scan to see how big the
lymph nodes are. Lymph nodes that are bigger than usual are more likely
to have cancer. Those lymph nodes can be biopsied to see if they
contain cancer. If lymph nodes in the upper part of the abdomen (the
para-aortic lymph nodes) are cancerous, doctors may want to do other
tests to see if the cancer has spread to other parts of the body.
Stage IVB
At this stage, the cancer has spread out of the pelvis to
other areas of the body. Stage IVB cervical cancer is not usually
considered curable. Treatment options include radiation therapy to
relieve the symptoms of cancer that has spread locally (near the
cervix) or distant metastases. Chemotherapy is often recommended. Most
standard regimens use a platinum compound (such as cisplatin or
carboplatin) along with another drug such as paclitaxel, gemcitabine,
topotecan, or vinorelbine. Clinical trials are testing other
combinations of chemotherapy drugs, as well as some other experimental
treatments.
Recurrent cervical cancer
Cancer that comes backs after treatment is called recurrent cancer.
Cancer can come back locally (in the pelvic organs near the cervix) or
come back in distant areas (spread through the lymphatic system and/or
the bloodstream to organs such as the lungs or bone).
If the cancer has recurred in the pelvis only, extensive
surgery (by pelvic exenteration) may be an option for some patients.
This operation may successfully treat 40% to 50% of patients. (See the
discussion under Surgery in the section, "How
is cervical cancer treated?") Sometimes radiation or
chemotherapy may be used for palliative treatment (treatment to relieve
symptoms but not expected to cure).
If your cancer has recurred in a distant area, chemotherapy or
radiation therapy may be used to treat and relieve specific symptoms.
If chemotherapy is used, you should understand the goals and
limitations of this therapy. Sometimes chemotherapy can improve your
quality of life, and other times it can diminish it. You need to
discuss this with your doctors. Fifteen percent to 25% of patients may
respond at least temporarily to chemotherapy.
New treatments that may benefit patients with distant
recurrence of cervical cancer are being evaluated in clinical trials.
You may want to think about participating in a clinical trial.
