After adult Hodgkin lymphoma has been diagnosed, tests are
done to find out if cancer cells have spread within the lymph system or to
other parts of the body.
There are three ways that cancer spreads in the body.
Stages of adult Hodgkin lymphoma may include
A, B, E, and S.
The following stages are used for adult Hodgkin
lymphoma:
Stage I
Stage II
Stage III
Stage IV
Adult Hodgkin lymphoma may be grouped for treatment as follows:
Early Favorable
Early Unfavorable
Advanced Favorable
Advanced Unfavorable
After adult Hodgkin lymphoma has been diagnosed, tests are
done to find out if cancer cells have spread within the lymph system or to
other parts of the body.
The process used to find out if cancer
has spread within the lymph
system
or to other parts of the body is called staging. The information gathered from the staging
process determines the stage
of the
disease. It is important to know the stage in order to plan treatment.
The following tests and procedures may be used in the staging process:
CT scan
(CAT
scan): A procedure that makes a series of detailed pictures of areas inside the
body, taken from different angles. The pictures are made by a computer
linked to an x-ray
machine. A dye
may be injected
into a vein
or swallowed to help the organs
or tissues
show up more clearly. This
procedure is also called computed tomography, computerized tomography, or
computerized axial tomography. For adult Hodgkin
lymphoma, CT scans of the neck, chest, abdomen, and pelvis
are taken.
PET-CT scan: A procedure that combines the pictures from a positron emission tomography (PET) scan
and a computed tomography (CT) scan. The PET and CT scans are done at the same time on the same machine. The pictures from both scans are combined to make a more detailed picture than either test would make by itself.
A PET scan is a procedure to find malignanttumorcells
in the body. A small amount of radioactiveglucose
(sugar) is injected into a vein. The PET scanner
rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
Bone marrow aspiration and biopsy: The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist
views the bone marrow, blood, and bone under a microscope
to look for signs
of cancer. Bone marrow aspiration and biopsy. After a small area of skin is numbed, a bone marrow needle is inserted into the patient’s hip bone. Samples of blood, bone, and bone marrow are removed for examination under a microscope.
For pregnant
women with Hodgkin lymphoma, staging tests that protect the fetus
from the harms of radiation
are used. These include:
MRI
(magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Ultrasound
exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues
or organs
and make echoes. The echoes form a picture of body tissues called a sonogram.
There are three ways that cancer spreads in the body.
Tissue. The cancer spreads from where it began by growing into nearby areas.
Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels
to other parts of the body.
Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels
to other parts of the body.
Stages of adult Hodgkin lymphoma may include
A, B, E, and S.
Adult Hodgkin lymphoma may be described as
follows:
A: The patient does not have B symptoms (fever, weight loss, or night sweats).
B: The patient has B symptoms.
E: Cancer is found in an organ
or tissue
that is not part of the lymph
system but which may be next to an involved area of the lymph system.
The following stages are used for adult Hodgkin
lymphoma:
Stage I
Stage I adult Hodgkin lymphoma. Cancer is found in one or more lymph nodes in one lymph node group. In stage IE (not shown), cancer is found outside the lymph nodes in one organ or area.
Stage II: Cancer
is found in two or more lymph node
groups either above or below the diaphragm
(the thin muscle below the lungs
that helps breathing and separates the chest
from the abdomen).Stage II adult Hodgkin lymphoma. Cancer is found in two or more lymph node groups, and both are either above (a) or below (b) the diaphragm.
Stage IIE: Cancer is found in one or more lymph node
groups either above or below the diaphragm
and outside the lymph nodes in a nearby organ
or area.Stage IIE adult Hodgkin lymphoma. Cancer is found in one or more lymph node groups above or below the diaphragm and outside the lymph nodes in a nearby organ or area (a).
Stage III
Stage III adult Hodgkin lymphoma. Cancer is found in one or more lymph node groups above and below the diaphragm (a). In stage IIIE, cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area (b). In stage IIIS, cancer is found in lymph node groups above and below the diaphragm (a) and in the spleen (c). In stage IIIS plus E, cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area (b), and in the spleen (c).
Stage III
is divided
into stage III, stage IIIE, stage IIIS, and stage IIIE,S.
Stage III: Cancer
is found in lymph node
groups above and below the diaphragm
(the thin muscle below the lungs
that helps breathing and separates the chest from the abdomen).
Stage IIIE: Cancer is found in lymph node
groups above and below the diaphragm
and outside the lymph nodes in a nearby organ
or area.
Stage IIIE,S: Cancer is found in lymph node
groups above and below the diaphragm, outside the lymph nodes in a nearby organ
or area, and in the spleen.
Stage IV
Stage IV adult Hodgkin lymphoma. Cancer is found outside the lymph nodes throughout one or more organs (a); or outside the lymph nodes in one organ and has spread to lymph nodes far away from that organ (b); or in the lung, liver, or bone marrow.
is found outside the lymph nodes
throughout one or more organs, and may be in lymph nodes near those organs; or
is found outside the lymph nodes in one organ and has
spread to areas far away from that organ; or
is found in the lung, liver, bone marrow, or cerebrospinal fluid
(CSF). The cancer has not spread to the lung, liver, bone marrow, or CSF from nearby areas.
Adult Hodgkin lymphoma may be grouped for treatment as follows:
