Survival Rate of Esophageal Carcinoma in Iran - A Systematic Review and Meta-analysis.
[esophageal carcinoma]
Esophageal
cancer
is
often
diagnosed
in
the
last
stages
where
the
chance
of
patient
's
survival
is
very
low
.
The
aim
of
this
systematic
review
was
presentation
of
valid
estimation
of
survival
in
patients
with
esophageal
cancer
in
different
regions
of
Iran
.
A
SYSTEMATIC
REVIEW
WAS
CARRIED
OUT
BASED
ON
THE
RELIABLE
DOMESTIC
MEDICAL
DATABASES
INCLUDING
:
SID
,
Magiran
,
Irandoc
and
Iranmedex
as
well
as
reliable
foreign
databases
like
PubMed
and
Scopus
using
"
Cancer
"
,
"
Esophagus
"
,
"
survival
"
"
Neoplasms
"
and
"
Longevity
"
as
keywords
.
Then
all
the
reviewed
articles
and
dissertations
which
met
the
entry
criteria
were
analyzed
.
The
data
were
analyzed
by
using
meta
-analysis
method
(
random
model
)
and
by
means
of
STATA
software
application
version
11
.

.
In
18
studies
the
total
numbers
of
2932
people
were
analyzed
.
The
one
year
survival
rate
in
Iran
is
estimated
at
47
percent
(
95
%
CI
:
34
-
61
)
and
the
five
year
survival
rate
is
estimated
at
12
%
(
95
%
CI
:
8
-
16
)
.
The
two
,
three
and
four
year
survival
rates
were
31
%
(
95
%
CI
:
18
-
44
)
,
22
%
(
95
%
CI
:
13
-
31
)
and
21
%
(
95
%
CI
:
4
-
38
)
,
respectively
.
According
to
the
findings
one
year
survival
rate
for
esophageal
cancer
in
Iran
is
almost
four
times
higher
than
its
five
year
survival
rate
.
Moreover
the
five
year
survival
rate
in
Iran
is
less
than
many
other
countries
.
