Cervical cancer affects the cervix,
which is a part of the female reproductive system. The cervix is the lowest
portion of a women's uterus (womb) and is located at the top of the vagina. The
cervix is made up of cells, which can change from being healthy to abnormal.
Cancer refers to a class of diseases
in which abnormal cells grow without control.
Cervical cancer
most commonly begins in the thin, flat cells that line the bottom of the
cervix. These are known as squamous cell carcinomas and account for
approximately eighty percent of cervical cancers. Cervical cancer can also
develop in the glandular cells that line the upper portion of the cervix. These
are known as adenocarcinomas and they make up about fifteen percent of cervical
cancer cases.
The most common
cause of cervical cancer is due to the human papillomavirus (HPV), a sexually
transmitted infection. Two strains in particular, 16 and 18, account for 75% of
cervical cancer cases. Other risk factors for developing cervical cancer
include women who smoke, have a weakened immune system, have a history of
multiple sexual partners, or have been infected with other sexually transmitted
infections.
Early cervical
cancer or early cervical pre-cancerous abnormalities generally produce no signs
or symptoms. The only way to detect early cervical cancer is to have regular
pelvic examinations that include a Pap smear. Pap tests can detect abnormal
cells in and around the cervix that may suggest precancerous or cancerous
changes. Symptoms may appear when the cancer is more advanced and has spread to
nearby areas. The following are signs and symptoms that may be present at the
time of diagnosis:
·
vaginal bleeding after intercourse, between periods or after
menopause
·
watery, bloody vaginal discharge
·
pelvic pain or pain during intercourse
Whether you're
the one, who's been diagnosed, or a family member or loved one, determining the
right treatment option can be difficult. If caught early cervical cancer can
often be cured. Treatment options vary depending on the stage of the disease.
The stage of cervical cancer describes its size, depth of invasion, and how far
it has spread. For most stages of cervical cancer treatment options may include
surgery, radiation, chemotherapy, or a combination of methods.
Robotic Radical Hysterectomy
The cornerstone
surgical option in the treatment of cervical cancer is the radical
hysterectomy. This procedure is different from a simple hysterectomy in that it
requires more extensive and delicate dissection of the tissues supporting the
uterus. The delicate tissues that are involved in the surgery are the ureter
and the bladder. The ureter is the tube that connects the kidney to the
bladder. This structure needs to be safely mobilized in order to remove the
appropriate tissues surrounding the uterus. Other supporting structures, such
as the uterosacral ligament, are also partially removed during a radical
hysterectomy. The da Vinci® surgical system allows us to perform these delicate
procedures with extreme precision.
Robotic Radical Parametrectomy
Cervical cancer
may often not be diagnosed at the time of initial hysterectomy. If cervical
cancer is found after a simple hysterectomy it may be necessary to perform an
additional procedure to remove the surrounding tissues of the cervix to ensure
complete removal of the cancer. A surgical option in this case would be
to perform a Radical Parametrectomy. A radical parametrectomy involves
removing the tissues that originally supported the cervix and uterus and also
involves delicate handling of the ureter and the bladder. The da Vinci®
surgical system helps us perform this delicate operation with great precision.
Fertility
Preservation and Cervical Cancer Treatment
If cervical
cancer is found at an early stage there may be options for women who wish to
preserve future fertility. A robotic trachelectomy involves removing only the
cervix. While it is common for women to undergo a complete hysterectomy for
cervical cancer, an option for selected women includes removing only the cervix
and the surrounding supporting tissues while leaving the body of the uterus,
tubes, and ovaries in place. The vagina is then connected to the body of the
uterus and allowed to heal. The da Vinci® surgical system allows us to manuever
around the uterus and remove only the necessary tissues required for the
treatment of early stage cervical cancer.
