The uterine cervix is a cylindrical, fibrous organ that is an average of 3 to 4 cm in length. The portio of the cervix is visible on vaginal inspection. The opening of the cervix is termed the external os. The os is the beginning of the endocervical canal, which forms the inner aspect of the cervix. At the upper aspect of the endocervical canal is the internal os, a narrowing of the endocervical canal. The narrowing marks the transition from the cervix to the uterine body. The endocervical canal beyond the internal os is termed the endometrial canal.</p><p id="CDR0000062759__669">The cervix is lined by two types of epithelial cells: squamous cells at the outer aspect and columnar, glandular cells along the inner canal. The transition between squamous cells and columnar cells is an area termed the squamocolumnar junction. Most precancerous and cancerous changes arise in this zone. </p><div class="graphic"><a href="/core/lw/2.0/html/tileshop_pmc/tileshop_pmc_inline.html?title=Image%20CDR0000609921&p=BOOKS&id=605484_CDR0000609921.jpg" target="tileshopwindow" class="inline_block pmc_inline_block ts_canvas img_link" title="Click on image to zoom"><div class="ts_bar small" title="Click on image to zoom"></div><img src="/books/NBK66058/bin/CDR0000609921.jpg" alt="Anatomy of the female reproductive system; drawing shows the uterus, myometrium (muscular outer layer of the uterus), endometrium (inner lining of the uterus), ovaries, fallopian tubes, cervix, and vagina." class="tileshop" title="Click on image to zoom" /></a></div></div><div id="CDR0000062759__532"><h3>Pathogenesis</h3><p id="CDR0000062759__533">Cervical carcinoma begins at the squamocolumnar junction. It can involve the outer squamous cells, inner glandular cells, or both. The precursor lesion is
|
|
dysplasia: cervical intraepithelial neoplasia (CIN) or adenocarcinoma <i>in situ</i>,
|
|
which can subsequently become invasive cancer. This process can be quite slow.
|
|
Longitudinal studies have shown that in patients with untreated <i>in situ</i>
|
|
cervical cancer, 30% to 70% will develop invasive carcinoma over a period of 10
|
|
to 12 years. However, in about 10% of patients, lesions can progress from <i>in
|
|
situ</i> to invasive in less than 1 year. As it becomes invasive, the
|
|
tumor breaks through the basement membrane and invades the cervical stroma.
|
|
Extension of the tumor in the cervix may ultimately manifest as ulceration,
|
|
exophytic tumor, or extensive infiltration of underlying tissue, including
|
|
the bladder or rectum.

</p><div id="CDR0000062759__713"><h3>Diagnosis</h3><p id="CDR0000062759__714">Treatment of cervical cancer in pregnancy is predicated on the extent of disease and the gestational age at diagnosis. Patients should undergo biopsy as needed and imaging to establish the extent of disease to make the most informed choices. The most appropriate imaging modality in pregnancy is magnetic resonance imaging, when indicated. </p></div><div id="CDR0000062759__808"><h3>Treatment of Stage I Disease</h3><p id="CDR0000062759__809">Pregnancy does not alter the course of cervical cancer. As a result, in certain cases, patients may elect to postpone treatment until its effects on the pregnancy are minimized. This may be considered for patients with the more common and less aggressive histological subtypes: squamous, adenocarcinoma, and adenosquamous. Patients with high-risk subtypes, such as small cell or neuroendocrine tumors, should be counseled toward immediate treatment despite the effects on the fetus, given their risk of progression.</p><p id="CDR0000062759__810">Patients with early stage (IA) disease may safely undergo fertility-sparing treatments, including cervical conization or radical trachelectomy, as indicated. The optimal timing for this procedure is in the second trimester, before fetal viability. Some authors have suggested waiting until the completion of a pregnancy to initiate treatment.[<a class="bibr" href="#CDR0000062759_rl_798_1" rid="CDR0000062759_rl_798_1">1</a>] For patients with IA2 and IB disease, such a delay may also be safe, but because of a risk of lymphatic spread, assessment of lymph-node status should first be ascertained. The status is best determined surgically via a laparoscopic or open lymph-node dissection, which can be safely performed up to approximately 20 weeks of pregnancy.[<a class="bibr" href="#CDR0000062759_rl_798_2" rid="CDR0000062759_rl_798_2">2</a>,<a class="bibr" href="#CDR0000062759_rl_798_3" rid="CDR0000062759_rl_798_3">3</a>] In patients without lymphatic spread, waiting for fetal viability to initiate treatment is an option. Patients with positive lymph nodes should be counseled toward immediate treatment. </p></div><div id="CDR0000062759__719"><h3>Treatment of Stages II, III, and IV Disease</h3><p id="CDR0000062759__720">For patients with stage II or greater disease, waiting for fetal viability is generally not acceptable.[<a class="bibr" href="#CDR0000062759_rl_798_4" rid="CDR0000062759_rl_798_4">4</a>] The standard of care is curative intent chemotherapy and radiation therapy. This treatment is toxic to the fetus and, without ovarian transposition, will render the ovaries nonfunctional after treatment. Evacuation of the fetus should be performed before radiation is initiated. When this is not possible, the radiation will generally cause a spontaneous abortion 3 to 5 weeks after initiating treatment. </p></div><div id="CDR0000062759__721"><h3>Neoadjuvant Chemotherapy</h3><p id="CDR0000062759__722">Neoadjuvant chemotherapy has been offered to patients with locally advanced disease as a way to initiate treatment while maintaining the pregnancy.[<a class="bibr" href="#CDR0000062759_rl_798_1" rid="CDR0000062759_rl_798_1">1</a>] Most chemotherapy agents can be initiated safely in the second trimester of pregnancy and beyond; mild growth restriction of the fetus is the most common side effect. Restriction of growth has been reported in a relatively small number of patients, and data are lacking on long-term outcomes for these women. As a result, this strategy should be considered with caution. Most of the patients in the reports underwent standard treatment (either surgery or radiation therapy) after completion of the pregnancy. </p></div><div id="CDR0000062759_rl_798"><h3>References</h3><ol><li><div class="bk_ref" id="CDR0000062759_rl_798_1">Morice P, Uzan C, Gouy S, et al.: Gynaecological cancers in pregnancy.
