The most common kind of uterine cancer
is the endometrical cancer which accounts for 95% the other is uterine sarcoma
which develop in the
muscle and accounts for only 59% of uterine cancer.
Endometrical cancer usually
adenocarcinoma of the endometrium of the fundus or body of the uterus is the
most common gynecologic cancer.
Most patients are post menopausal with
average age of 61 at the time of diagnosis.
Endometrial cancer can be caused by
hormonal imbalance; when there is unopposed oestrogen circulation with no or
low progesterone in the uterus to grow thicker; if this build up continues, and
stays that way, cancer cells can start to grow.
RISK FACTORS
Family history of cancer
Diabetes mellitus
Previous radiation therapy
Obesity hypertension, nulliparity, low
parity
CLINICAL MANIFESTATION
In over 90% of cases there is abnormal
uterine bleeding this could be pre or postmenopausal.
Watery usually malodorous (unpleasant
smelling) vaginal discharge
Pain during sexual intercourse
Pelvic pain, bowel and bladder
dysfunction are late signs
Anaemia secondary to bleeding
DIAGNOSTIC EVALUATION
·
On
pelvic and rectovaginal examinations, enlarged uterus may be palpated
·
Endocervical
aspirations shows abnormal cell growth
·
Endometrial
biopsy result may be false (negative)
·
Dilation
and curettage most accurate diagnostic tool; hysteroscopy and transvaginal
ultrasound may be helpful.
MEDICAL MANAGEMENT
•
Staging
for endometrical cancer is based on surgical aspects vs clinical staging.
a. Emphasis is placed on histologic grade,
depth of myometrial invasion and cervical involvement.
b.These parameters assist in
prediction of lymph node involvement and help determine need for lymph node dissection.
•
Stage
I: requires total abdominal hysterectomy with bilateral salpingo – oophorectomy
(TAH/BSO)
•
Advanced
stage I and stage II requires (TAH /BSO) and selective lymphonode dissection.
•
Radiation
therapy (intracavitary or external) may be added after surgery or chosen
instead of surgery for more advanced stages or for patients who are high-risk
surgical candidates.
Complications of Radiation Therapy
Hemorrhagic cystitis, virginities,
vaginal dryness, vaginal stenosis, bladder
dysfunction fistulas strictures leg oedema.
•
Hormonal
therapy:- progestational
agents magatte receptor sites in endometrial for oestrogen and thus decrease
growth/metastesis may provide stabilization to disease.
•
Chemotherapy
for metastatic and recurrent disease
