General Description
? Also called endometrial cancer
? Endometrial cancer is one of the
most common malignancy of female
genital tract.
General Description
? A malignant epithelial
disease that occurs in
endometrial gland of uterus
? The incidence of
endometrial cancer is
increasing worldwide in
recent years.
Risk Factors
1,Medical conditions
a,Diabetes mellitus,hypertension.
b,Overweight---obesity (excess
estrogen as a result of peripheral
conversion of adrenally derived
androstenedione by aromatization in
fat).
c,Late menopause,
Risk Factors
2,Some gynecologic diseases
( Long-term endogenous estrogen
exposure )
- polycystic ovary syndrome
- functioning ovarian tumors
- anovulating dysfunctional bleeding
- Infertility,Nulliparity.
Risk Factors
3,Prolonged Use of estrogen
a,Prolonged menopausal estrogen
replacement therapy without
progestogen.
b,Prolonged use of the antiestrogen
tamoxifen for breast cancer.
Risk Factors
4,Genetic factors and other factors
a,Endometrial and ovarian cancer are the
simultaneously occurring with other
genital malignancy,reported incidence
(1.4~3.8%).
b,Family history of tumor is higher.(12-
28%)
Classification
? Estrogen dependent and estrogen
independent are two different pathogenetic
types:
-- One with history of exposure to
unopposed estrogen (either
endogenous or exogenous).
-- Other type with no source of estrogen
stimulation of endometrium.
Five histological subtypes
? Endometrioid adenocarcinoma
? Mucinous carcinoma
? Serous adenocarcinoma
? Clear cell carcinoma
? Other rare subtypes
Five histological subtypes
--Endometrioid Adenocarcinoma
? Account for about
80~90%.
? Well differentiated.
? Prognosis is better.
Five histological subtypes
--Mucinous carcinoma
Rare (about 5%)
a,Most of them is a well differentiated.
b,Behavior is similar to that of
common endometrial carcinoma.
Five histological subtypes
--Serous adenocarcinoma
a,Architecture is identical with
complex papillary.
b,More aggressively with deep
myometrial and lymphatic invasion.
c,Simulating the behavior of ovarian
carcinoma.
Five histological subtypes
--Clear cell carcinoma
a,A rare subtype
b,Is high grade and aggressive
c,Prognosis is similar to or worse than that
of papillary serous carcinoma
d,Survival rate is lower 33%~64%
Five histological subtypes
--other rare subtypes
? Squamous adenocarcinoma
? Undifferentiated carcinoma
? Mixed adenocarcinoma
Metastasis Route
? Direct extension
? Lymphatic metastasis,important route
? Hematogenous metastasis
Clinical Features--Symptoms
? Abnormal vaginal bleeding
(premenopausal or postmenopausal,
minimal or nonpersistant)
? Abnormal vaginal discharge(25% infection
of uterine contents)
? Pelvic pressure or discomfort (uterine
enlargement or extrauterine disease
spread)
Clinical Features--Signs
? No evidence in early stage on
physical examination
? Slight enlargement of uterine size
and soft
? Uterus fixed,immobile,adenexal
mess in advanced stage
Special Examination
Dilation and fractional curettage ( D,C)
– Most effective,definitive procedure and
commonly used
– Significance
-Established correct diagnosis,clinical
stage
-differentiated from cervical cancer or
cervical involvement
? Ultrasonography
– Useful adjuvant method
– Significances
? Size of lesion
? Invasion of endometrium or cervix
? Resistant index of new vessels
Endometrial carcinoma in a 58-year-old woman with substantial
postmenopausal bleeding,(A) Sagittal transvaginal US scan shows the
endometrium with a thickness of 44 mm and a large area of mixed
echogenicity suggestive of a mass,(B) Transverse sonohysterogram shows
a 50-mm-diameter polypoid mass protruding into the endometrial cavity
(calipers indicate the stalk of the mass),Histopathologic findings indicated
poorly differentiated endometrial carcinoma.
A B
Hysteroscopy
–Significance
-Direct observation
-Taking sample correctly
-Identifying polyps and submucous myoma
Pap test
-Unreliable diagnostic test
-30%-50% abnormal pap test results
Others
-MRI,CT,chest x-ray,IV urography,
cystoscopy,sigmoidoscopy,
Diagnosis
? History,symptoms,related
risk factors
? Diagnostic methods
Differential Diagnosis
? Senile endometritis / vaginitis
? Dysfunctional uterine bleeding
? Submucous myoma / Endometrial
polyps
? Cervix cancer / Sarcoma of uterus/
Primary carcinoma of fallopian tube
Clinical Stage
(FIGO 1971)
? Stage I
Ia The carcinoma is confined to the corpus and
the length of the uterine cavity is ≤ 8 cm
Ib The carcinoma is confined to the corpus and
the length of the uterine cavity is > 8 cm
? Stage II The carcinoma has involved the corpus and the
cervix,but has not extended outside the uterus
Clinical Stage
(FIGO 1971)
? Stage III The carcinoma has extended outside the
uterus,but not outside the true pelvis
? Stage IV
IVa The carcinoma has extended outside the
uterus and involves the mucosa of the bladder or rectum
(a bullous oedema as
such does not permit the case to be allotted to Stage IV)
IVb The carcinoma has extended outside the true
pelvis and spread to distant organs
Surgical pathologic staging
(FIGO 1988)
? Stage I
Ia* Tumour limited to the endometrium
Ib* Invasion to less than half of the myometrium
Ic* Invasion equal to or more than half of the
myometrium
? Stage II
IIa* Endocervical glandular involvement only
IIb* Cervical stromal invasion
Surgical pathologic staging
(FIGO 1988)
? Stage III
IIIa* Tumour invades the serosa of the corpus
uteri and/or adnexae and/or positive cytological findings
IIIb* Vaginal metastases
IIIc* Metastases to pelvic and/or para-aortic lymph
nodes
? Stage IV
IVa* Tumour invasion of bladder and/or bowel
mucosa
IVb* Distant metastases,including intra-
abdominal metastasis and/or inguinal lymph nodes
Stage Ia*
Tumor limited to the endometrium
Stage Ib*
Invasion to less than half of the myometrium

MMC,VP16.
Hormone Therapy
? Most endometrial cancers have both ER
& PR.(Estrogen dependent subtype)
? Progestin
– Indications,advanced stage
recurrent cancer
Prognostic Factors
? Age
? Cell type
? Histological grade
? Depth of myometrium infiltration
? lymph-node metastasis
? Presence of lymph vascular
space involvement
