ovarian neoplasms ovarian cancer is the
00:05
fifth most common cause of cancer death
00:07
in women in the United States ovarian
00:10
cancer has the highest mortality rate
00:11
among gynecologic malignancies
00:13
approximately 55% of patients will die
00:15
within five years of diagnosis the
00:18
objectives of this video are to describe
00:19
the initial management of a patient
00:21
within an X amass compare the
00:23
characteristics of functional cysts
00:25
benign ovarian neoplasms and ovarian
00:27
cancers list the risk factors and
00:29
protective factors for ovarian cancer
00:31
describe the symptoms and physical
00:33
findings associated with ovarian cancer
00:35
and lastly describe the three
00:37
histological categories of a very
00:39
neoplasm what is an in Exel mass and
00:43
gynecology it refers to anything next to
00:45
the uterus usually involving the
00:47
fallopian tube or ovary the term adnexal
00:50
mass is often used interchangeably with
00:52
the term mass when a patient presents
00:54
with an x amass it is important to
00:56
perform a thorough pelvic examination
00:58
for preman Arkell girls the ovary should
01:01
not be palpable for reproductive age
01:03
group women a normal ovary is palpable
01:06
about half of the time and for
01:07
postmenopausal women the ovaries are
01:09
usually not palpable 25% of ovarian
01:12
tumors in postmenopausal women are
01:14
malignant whereas 10% of our variant
01:17
tumors in reproductive age women are
01:18
malignant pelvic ultrasound is the
01:21
primary component of evaluation of an
01:23
annexe amass the three main
01:25
classifications of an exhalation Allah
01:28
cysts number two benign ovarian
01:30
neoplasms and number three malignant
01:32
ovarian neoplasms functional cysts are
01:35
physiologic and formed from normal
01:37
ovulatory function they are composed of
01:40
follicular cyst and corpus luteum cysts
01:42
and they will spontaneously resolve
01:44
functional cysts require surgical
01:45
intervention only if they become
01:47
symptomatic for instance if the size
01:49
becomes large if there’s torsion or if
01:51
there’s uncontrolled bleeding into the
01:53
cysts which is known as a hemorrhagic
01:54
cyst
01:55
there are three histological cell types
01:57
that give arised a benign and malignant
01:59
ovarian neoplasms let’s spend a moment
02:02
to discuss these three cell types here
02:05
is the ovary and it is lined by
02:06
epithelial cells shown here in blue here
02:09
is a follicle and in the follicle there
02:12
are granulosus
02:13
and theca cells represented here in pink
02:16
these cells are referred to as the
02:17
stromal cells the third type of cell in
02:20
the ovary are the germ cells that are
02:21
the precursor cells to gametes
02:23
represented here in purple so it is
02:25
these three histological cell types
02:27
epithelial stromal and germ cell that
02:30
give a rise to benign and malignant
02:31
ovarian neoplasms there are multiple
02:35
specific benign and malignant tumors
02:37
within each of these three cell types we
02:40
will start with benign ovarian neoplasms
02:42
about 25% of an exome asses in
02:45
reproductive age women are benign
02:47
neoplasms the epithelial are the largest
02:50
class of ovarian neoplasms serous
02:52
mucinous and endometrioid are the most
02:54
common benign epithelial neoplasms the
02:57
germ cell type are derived from the
02:59
primary germ cell and thus may contain
03:01
relatively differentiated structures
03:03
such as hair and bone the mature cystic
03:05
teratoma known as a dermoid is the most
03:07
common tumor found in women of all ages
03:09
it is often in premenopausal women and
03:12
demonstrate tissues of all three
03:13
embryologically cell types ectodermal
03:15
mesodermal and endodermal lastly the
03:18
stromal cell type benign ovarian
03:20
neoplasm is derived from specialized sex
03:22
cord stroma of the developing gonad two
03:25
examples are fibromas or the– comas
03:27
Manx syndrome is a benign ovarian
03:30
fibroma plus society’s plus a right
03:32
pleural effusion let’s now move to
03:34
malignant ovarian neoplasms epithelial
03:37
cell type consists of 90 percent of all
03:39
ovarian malignancies serous endometrial
03:43
mucinous and clear cell are all
03:45
epithelial malignant ovarian neoplasms
03:47
the germ cell type is the most common
03:50
ovarian cancer in women less than 20
03:51
years old
03:52
these may be functional producing beta
03:54
HCG or alpha-fetoprotein dis German
03:57
Oma’s endodermal sinus tumors and
03:59
immature teratomas are examples of germ
04:02
cell malignant ovarian neoplasms and
04:04
lastly sex chord stromal type produce
04:07
hormones granulosa cells – MERS may
04:09
secrete large amounts of estrogen and
04:10
sertoli related tumors may secrete large
04:13
amounts of androgen these sex chord
04:15
stromal tumors are rare let’s move now
04:17
to patient presentation from malignant
04:19
ovarian neoplasms women most commonly
04:22
present in their fifth decade of life
04:24
and they may present with abdominal
04:26
bloating
04:27
distension abdominal or pelvic pain
04:29
early satiety urinary urgency or
04:31
decreased energy it is important to note
04:34
that the most common symptoms are
04:35
gastrointestinal and not gynecological
04:38
symptoms approximately one out of 70
04:40
women will develop ovarian cancer during
04:42
her lifetime and risk factors include
04:44
Nullah parity primary and fertility
04:46
endometriosis and inherited mutations
04:48
such as BRCA and hnpcc protective
04:52
factors on the other hand include taking
04:54
oral contraception for at least five
04:56
years having a history of a tubal
04:58
ligation or history of a hysterectomy
05:00
moving now to evaluation it is very
05:03
important for both the patient and her
05:04
clinician to be aware of early warning
05:06
signs of ovarian cancer for radiological
05:09
imaging pelvic ultrasound is the best
05:12
first line test and a ca-125 is most
05:15
helpful in postmenopausal woman with a
05:17
pelvic mass this is because there are
05:19
many cases of elevated ca-125 in
05:21
premenopausal women for reasons such as
05:23
fibroids PID and endometriosis that make
05:26
it less useful surgical exploration is a
05:29
definitive next step in the evaluation
05:31
when there is a high suspicion this
05:33
concludes the aapko video on our variant
05:35
neoplasms we’ve discussed the
05:37
characteristics and management of
05:39
functional sister line ovarian neoplasms
05:41
and malignant ovarian neoplasms as well
05:43
as discussing the risk factors and
05:45
protective factors for ovarian cancers
05:47
remember to always have a high clinical
05:49
suspicion to rule out ovarian cancer
