NCCN Guidelines for Patients
Ovarian Cancer, Version 1.2017
Stage I ovarian cancer
(on page 45) shows the primary treatment
options for newly diagnosed stage I ovarian cancer.
For ovarian cancer confirmed by a prior surgery,
see Guide 4. Stage I ovarian cancer is when cancer
is only in the ovaries and has not spread to other
tissues or organs.
Primary treatment is the main treatment used to
rid the body of cancer. Surgery is used as primary
treatment for stage I ovarian cancer. Surgery is also
used to find out how far the cancer has spread—
called surgical staging. The type and extent of
surgery you will have depends on the cancer stage
and other factors. For full details on each surgery,
see page 35.
Primary treatment options
The most common treatment for stage I ovarian
cancer is surgery to remove both ovaries, both
fallopian tubes, and the uterus. This is the only
recommended option when cancer is in both
ovaries—stage IB. If cancer is only in one ovary—
stage IA or IC—a second option is surgery to remove
the ovary with cancer and its fallopian tube. This is
called fertility-sparing surgery. It may be used if you
want to be able to have babies after treatment.
Along with either of these options, you will also have
surgical staging. Surgical staging involves taking
biopsy samples of the tumor and nearby tissues to
test for cancer cells. It is done to check for cancer
cells that have spread outside the ovaries or pelvis
and can only be seen with a microscope. These
are called microscopic metastases. During surgical
staging, biopsy samples will be taken from organs
and tissues where ovarian cancer often spreads.
The omentum and nearby lymphs will also be
After completing primary treatment, see Guide 5 on
