Lymphoid neoplasm incidence by WHO subtype in Australia 1982-2006.
[hodgkin lymphoma, classical]
There
are
limited
data
characterizing
the
subtype-
specific
incidence
of
lymphoid
neoplasms
in
the
World
Health
Organization
(
WHO
)
Classification
era
.
Data
were
obtained
on
all
incident
lymphoid
neoplasms
registered
in
Australia
during
1982
-
2006
.
Subtypes
were
grouped
using
the
InterLymph
nested
hierarchical
classification
,
based
on
the
2008
WHO
Classification
.
Temporal
trends
were
examined
using
Joinpoint
regression
;
average
annual
percentage
change
in
incidence
was
computed
.
Multiple
Poisson
regression
was
used
to
compare
incidence
by
sex
and
age
.
The
incidence
of
all
non-
Hodgkin
lymphoma
(
NHL
)
increased
by
2
.
5
%
/
year
during
1982
-
1996
and
was
stable
thereafter
.
During
1997
-
2006
,
several
mature
B-
and
natural
killer
(
NK
)
-
/
T
-
cell
NHL
subtypes
increased
in
incidence
,
including
diffuse
large
B-
cell
(
1
.
3
%
/
year
)
,
follicular
(
2
.
5
%
/
year
)
,
Burkitt
(
6
.
8
%
/
year
)
,
marginal
zone
(
13
.
2
%
/
year
)
,
mantle
cell
(
4
.
2
%
/
year
)
,
peripheral
T-
cell
lymphoma
(
4
.
7
%
/
year
)
and
plasmacytoma
(
7
.
1
%
/
year
)
.
While
chronic
lymphocytic
leukemia
incidence
was
stable
,
small
lymphocytic
lymphoma
incidence
declined
(
8
.
1
%
/
year
)
.
Hodgkin
lymphoma
(
HL
)
incidence
increased
during
1997
-
2006
(
2
.
2
%
/
year
)
,
both
classical
(
4
.
3
%
/
year
)
and
nodular
lymphocyte
predominant
(
12
.
1
%
/
year
)
HL
.
Diagnostic
artifact
,
evidenced
by
a
sustained
decline
in
the
incidence
of
NHL
not
otherwise
specified
(
NOS
;
5
.
8
%
/
year
)
and
lymphoid
neoplasms
NOS
(
5
.
6
%
/
year
)
,
limits
the
interpretation
of
temporal
trends
for
some
subtypes
.
A
marked
male
predominance
was
observed
for
almost
all
subtypes
.
Incidence
of
mature
B-
and
NK-
/
T
-
cell
NHL
subtypes
increased
sharply
with
age
,
except
for
Burkitt
lymphoma
/
leukemia
.
For
HL
subtypes
,
a
bimodal
age
distribution
was
only
evident
for
nodular
sclerosis
HL
.
Variation
in
incidence
patterns
over
time
and
by
sex
and
age
supports
etiological
differences
between
lymphoid
neoplasm
subtypes
.
