To My
Patients,
Cervical and Uterine Cancer Update
Cervical
cancer
remains the number one cancer in women and the number two cause of
death from malignancy worldwide. It is particularly prevalent in
third-world countries where Pap Smears are not available.
In the U.S.,
cervical cancer is the thirteenth cause of cancer death in women.
It is caused by the HPV virus, which is sexually transmitted.
Adenocarcinoma of the cervix is a different type of cervical cancer
that arises from the inner canal of the cervix rather than from the
outer surface. It is not as common as the squamous cell carcinoma,
but is harder to detect by a Pap Smear.
Screening
should be initiated within three years of intercourse or no later
than 21 years of age. It should be done annually if conventional
pathology testing is used. If a liquid-based cytology (ThinPrep) is
used, then Paps can be done every other year if the patient has
three consecutive normal tests. An annual pelvic exam is still
recommended. If a patient has had a hysterectomy, then no further
Paps are required if the surgery was done for benign disease. Any
women with a history of abnormal Paps, DES exposure, or who is
immuno-compromised should continue with regular Pap smears even
after a hysterectomy. Again, annual pelvic exams are still
recommended for women who have had a hysterectomy.
If a patient
has ASCUS (atypical squamous cells of undetermined significance)
then the pap should be repeated. If that pap shows ASCUS again,
then colposcopy with cervical biopsies are necessary since ASCUS is
the most common Pap test diagnosis before invasive cancer is
detected.
It is better
not to have a pap test if the patient is on her menstrual cycle or
if she has a significant vaginal infection.
Postmenopausal
bleeding is the most common symptom for uterine or endometrial
cancer. About 12 – 15% of women with bleeding after the
menopause have this cancer.
Endometrial
biopsy in the office or a transvaginal ultrasound are options for
evaluation of postmenopausal bleeding. However, if the ultrasound
shows an endometrial thickening of 5 mm or greater, then sampling of
the uterine cavity must be done.
The best test
is an outpatient hysteroscopy with a D and C for endometrial
specimens. While saline infusion sonohysteroscopy is as accurate as
a hysteroscopy, there is some risk that cancer cells can be pushed
out of the uterus into the pelvis during this technique.
In our office,
we recommend and prefer to use liquid-based cytology Pap (ThinPrep)
testing on all patients, however, not all Insurance Companies /
Payors will reimburse for this type of testing. Determination of
coverage may depict which type of Pap Smear is a covered benefit.
Any women with
bleeding after menopause must be thoroughly evaluated to rule out
polyps or uterine cancer.
