Fourfold ovarian cancer risk ?

Kemal Atlay ENDOMETRIOSIS is linked
to a fourfold higher risk of
ovarian cancer , suggests a US
population-based study of
nearly half a million women .
Researchers identified
an even higher cancer risk ,
almost 10-fold , in women
with more severe disease
subtypes , such as deep infiltrating
endometriosis and
ovarian endometriomas .
“[ These women ] may benefit
from counselling regarding
ovarian cancer risk … and
could be an important population
for targeted screening
and prevention studies ,” they
wrote in JAMA .
Using health records from
a statewide database , the
University of Utah – led team
looked at 79,000 women
with endometriosis ( a mean
age at diagnosis of 36 ) and
372,000 age-matched controls
, followed for an average
of 12 years post-diagnosis .
Those with endometriosis
were more likely to be nulliparous
and to have undergone
a hysterectomy compared
with the controls .
Overall , there were 225
ovarian cancer diagnoses in
the endometriosis group and
372 in the control group .
Women with endometriosis
were 7.5 times more likely
to develop type I ovarian cancer
, including mucinous , clear
cell , endometrioid and lowgrade
serous carcinomas .
The likelihood of type II ,
or high-grade serous , ovarian
cancer was also elevated with
endometriosis but to a lesser
extent ( 2.7-fold higher risk ).
Diagnoses of superficial
peritoneal endometriosis and
other forms of the disease were
associated with a nearly threefold
higher risk of malignancy .
While the exact mechanism
linking endometriosis
subtypes and ovarian cancer
histotypes was unclear , the
researchers said there was
evidence of an overlapping
genetic predisposition . JAMA 2024 ; 17 Jul .
