This type of cancer is slow growing and may not

invade other tissue. An LMP tumor may be found

by chance during surgery or tests for another health

problem. Most often, it is diagnosed after surgery.

Surgery is also used as primary treatment for this

type of tumor.

There is more than one primary treatment option

for an LMP tumor. Your doctor will consider more

than one factor when deciding on treatment. First,

surgical staging will be done to assess the extent of

disease. Second, your doctor will check whether or

not invasive implants were found. Tumor cells that

spread and grow on the surface of nearby organs are

called noninvasive implants. The tumor cells rarely

grow into (invade) tissue—called invasive implants.

Lastly, he or she will factor in whether or not you

want to have babies after treatment. Fertility-sparing

surgery is always an option for an LMP tumor.

Observation with follow-up tests is an option for all


See Guide 17.

If surgical staging was complete and no invasive

implants were found, then this is the only option

recommended. If invasive implants were found, a

second option is to receive chemotherapy. If surgical

staging was not complete, then another option is to

have more surgery. This may include fertility-sparing

surgery and surgical staging procedures.

For surgical staging, biopsy samples will be taken

from the tumor and nearby tissues. The omentum

and nearby lymph nodes may also be removed. If

you don’t want to have babies, then you may have

completion surgery. Completion surgery removes the

remaining ovary (or ovaries), fallopian tubes, uterus,

omentum, and any tumor cells found on nearby

tissue. In some cases, nearby lymph nodes may also

be removed.

If invasive implants were found, then surgery may

be followed by chemotherapy. If no invasive implants

were found, then no other treatment is recommended

after either surgery. Instead, you will begin

observation with follow-up tests.
