Surgical therapy and prognosis of sarcomatoid carcinoma of the gallbladder.
[carcinoma of the gallbladder]
Sarcomatoid
carcinoma
of
the
gallbladder
is
rare
and
its
characteristics
are
poorly
understood
.
This
study
aimed
to
understand
the
behavior
and
prognosis
of
sarcomatoid
carcinoma
of
the
gallbladder
as
well
as
its
clinical
manifestations
and
survival
rate
of
patients
after
radical
or
palliative
surgery
,
and
to
review
the
reported
data
worldwide
and
our
10
patients
.
From
2004
to
2009
,
ten
patients
were
pathologically
diagnosed
with
sarcomatoid
carcinoma
of
the
gallbladder
and
underwent
operation
at
our
center
.
These
characteristics
,
clinical
presentations
,
tumor
-node-metastasis
(
TNM
)
staging
,
surgical
modes
,
and
prognosis
were
reviewed
,
retrospectively
.
We
collected
the
data
of
46
patients
reported
in
the
English
-
language
literature
worldwide
and
analyzed
the
survival
with
ours
.
The
survival
rate
was
estimated
using
the
Kaplan-
Meier
method
,
and
was
compared
using
the
log-rank
test
.
The
median
age
of
the
10
patients
was
67
years
(
inter-quartile
range
59
-
74
years
)
,
and
the
size
of
tumor
inter-quartile
ranged
from
3
.
1
to
7
.
9
cm
.
In
this
series
,
9
patients
received
radical
surgery
,
and
one
undewent
palliative
surgery
.
There
was
no
surgical
mortality
,
and
one
patient
underwent
a
second
operation
because
of
liver
metastasis
.
The
median
survival
time
of
the
patients
was
9
months
(
inter-quartile
range
6
-
12
months
)
,
with
3
patients
still
being
alive
until
follow-up
;
however
,
two
patients
had
tumor
recurrence
.
The
data
from
the
56
patients
(
10
patients
in
our
series
and
46
reported
elsewhere
)
statistically
indicated
that
the
median
age
was
66
years
(
inter-quartile
range
61
-
74
.
5
years
)
and
the
overall
median
survival
was
5
.
5
months
(
inter-quartile
range
2
.
5
-
10
months
)
.
The
survival
time
in
the
patients
undergoing
radical
surgery
(
n
=
42
)
was
significantly
longer
than
that
in
the
patients
undergoing
palliative
surgery
(
n
=
14
)
(
P
=
0
.
031
)
.
The
survival
of
the
patients
with
sarcomatoid
carcinoma
of
the
gallbladder
is
poor
.
Some
patients
may
die
shortly
after
the
surgery
because
of
recurrence
or
metastasis
.
However
,
radical
surgery
is
still
necessary
if
possible
.
