This is a very emotional blog post for me as
osteosarcoma was the type of cancer that killed Georgie. He was fifteen when
his jaw swelled up. At first he had a numb lip and weird tingling sensation. It
took a while to get to the bottom of what was wrong but we eventually found out
it was a tumour in the right mandible. After years of treatment and numerous
surgeries, Georgie passed away just months before his eighteenth birthday.
On average thirty children per year in the UK
develop osteosarcoma. This kind of cancer is more common in teenagers and is
usually found in boys. It is rare to see it in a child under the age of five.
Osteosarcoma starts in the bone, usually at the end
where new bone tissue forms as you grow. Any bone in the body can be affected,
with Georgie it was the jaw, but it is commonly found in the arms and legs. The
knee joint is a particularly common site for osteosarcoma.
The cause of osteosarcoma is unknown at the moment
but there are some risk factors to consider: people with Li Fraumeni Syndrome
are at more at risk of developing osteosarcoma, as are children who have
hereditary retinoblastoma. If a child has had radiotherapy or chemotherapy in
the past then they also have an increased risk.
INJURIES THAT DAMAGE BONES DO NOT CAUSE
OSTEOSARCOMA. THEY CAN, HOWEVER, DRAW ATTENTION TO ANY TUMOURS THAT ARE ALREADY
THERE.
Pain in the bone is the most common symptom of
osteosarcoma. This may be on and off for a while at first and then become more
severe and constant over time. Swelling may also occur. The bone can weaken and
break, which is how many osteosarcoma cases are discovered. Most symptoms can
be caused by something else so it is hard to know when to go to the doctor but
if your child has persistent pain and swelling in the bone – I would recommend
taking them for a check up.
To diagnose osteosarcoma, the doctor will do a
series of tests including x-rays. If a bone tumour is suspected then a specialist
will be needed to perform further tests such as biopsies. A physical
examination of the affected area and a blood test may also be required. Bone
scans, MRI’s and CT’s may also be required.
Treatment for osteosarcoma would
depend on the size, position, grading and stage of the tumour. Surgery is
usually a very important part of the treatment as is chemotherapy. Chemotherapy
is usually used to destroy the cancer cells and shrink the main tumour before
surgery is performed. It is then used again when surgery has been performed to
blast away anything microscopic that may have been left behind. This is to try
and reduce the chance of the cancer returning.
Radiotherapy
may also be considered as it can destroy cancer cells with high energy rays but
do little damage to the normal surrounding cells.
Surgery
would depend on the size and position of the tumour. The whole limb may need to
be amputated, especially if the cancer has spread to the surrounding nerves and
blood vessel. A prosthetic limb will be fitted. Obviously this is a major thing
and I don’t want to appear to not take this seriously. Your child’s doctor
should discuss this in a great amount of detail with you and both you and your
child should receive lots of support if amputation is the only option.
In
other cases, limb sparing surgery can be used to preserve the limb. This may
involve replacing the limb with a bone graft using part of another bone in the
body or it may involve replacing the bone with prosthesis. Georgie has his jaw
replaced with another bone part TWICE.
Even
with amputation, it should be possible for your child to adjust and still be
able to participate in “normal” activities and sports are still a possibility.
Long term effects should be discussed with you before surgery.
Osteosarcoma
can be a very aggressive type of cancer, and unfortunately, survival rates are
not very good. I have a particular hatred for this cancer type and I am hopeful
clinical trials and research will discover new ways of treating, curing and
preventing osteosarcoma. Please do visit my uncle’s site www.anticancer.org.uk for more
information as he is a fountain of knowledge on the subject, and as a parent of
a child, who had cancer, he is well informed and able to explain things much
better then I ever could.
My
heart it with you if you or someone you love is battling osteosarcoma or if you
have lost someone to it like I have.
As
always, for my wonderful warrior Georgie
