Call today. Is his doctor a pediatrician? Do you have a surgeon
involved in his surveilance? When was his last rectal exam? We do
not have our pediatrician do rectal exams because she does very few
of them and her finger is not educated. Our surgeon does many and
moreover her finger *knows* what the inside of a child's body should
feel like, and what a different kinds of tumor feel like, so we go
to her for that.
When was his last blood test for AFP?
When was his last MRI?
I know today is a Saturday but call anyway. Start planning all that
you must do to investigate this ASAP. You may be able to get the
AFP blood draw done today. Hope for the best but plan for the worst.
I am very sorry this is happening to you.

His limping raises the index of suspicion sky high. Push for an MRI
right now. Ultrasound will not show a solid tumor unless it is so large
that it displaces hollow organs. Ultrasound will show a cystic tumor
but not all tumors are cystic.
At various times the internal part of my daughter's SCT was invisible
on ultrasound. On MRI the tumor was very apparent.

First let me say I am so sorry this is happening. At this point there
is no confirmed recurrent tumor but the limping is a very scary sign.
My daughter had a surge in her AFP tumor marker. AFP is a marker for
a second, highly lethal kind of tumor that often occurs in teratomas:
endodermal sinus tumor. However, MRIs showed no clear evidence of a
recurrent mass, so there was nothing at that point for the surgeons to
do. Under the German protocol for teratoma management, we would have
started aggressive (and toxic) chemotherapy. However, the American
pediatric oncology study group for teratomas and related tumors favors
wait-and-see, and that is what we decided to do. It was a very tense
year, but eventually the AFP did go down.
Your son's AFP being essentially normal means that if his limping is
due to a tumor, it is a pure teratoma, not an endodermal sinus tumor
or mixture. He should probably have a blood test for human chorionic
gonadotropin (βhCG), a marker for the second most common other tumor
type found in teratomas: choriocarcinoma.
The treatment of choice for recurrent pure teratoma is surgery without
chemotherapy.
I have read most of the medical literature on SCTs and teratomas more
generally. The recurrence rate is generally low but it varies with
certain details of the tumor type and surgery. The pediatric surgery
literature often states that teratomas are benign and once removed
that is the end of the matter. That is usually true, but not always.
Pediatric oncologists tell me that nearly every child they see for a
recurrent teratoma had a surgeon who assured the family all was well.
I know some of these families myself. I hope yours is not among them.
In your shoes I would talk to the surgeon again and explain that the
limping is getting worse quickly. Also talk directly to the radiology
department. They always hold slots for emergency scans, and also they
have a protocol for filling last minute cancellations. Last minute
cancellations are common with MRIs, because children with coughs and
colds should not be given anesthesia. The radiologists can even swap
your son's slot with another patient, to scan your son earlier.
You also must closely monitor your son's bowel and bladder function.
A mass in the pelvis can cause obstruction of either, and obstruction
rapidly can become a medical emergency.
Do you have copies of your son's surgery and pathology reports? You'll
need those. Do you have an oncologist on your team, who has experience
with solid tumors? You need one.
Below are a few links to abstracts of papers in the medical literature.
Without reading your son's surgery and pathology reports, I cannot pick
the most relevant papers, but these should cover the bases. Do you
have a local library that does Interlibrary Loan (ILL)? The library
can get you copies of the papers for free, likely as PDF to you via
e-mail. Waiting time can be as little as a few hours, or a day or two.
Hugs,
Una

Mature and immature teratomas: results of the first paediatric Italian study.
She is a cancer survivor, and will require at least a low level of tumor
surveillance for the rest of her ife.
There are various protocols for estimating risk of recurrence based on
surgery and pathology findings. By one protocol, my daughter's initial
risk of recurrence was about 50%. When her AFP surged so did the risk
estimate, to nearly 100%. Now we are down to nearly 0%.
Surgeons do relatively little surveillance; that is why it helps to
consult an oncologist. Oncologists are experts at surveillance.
You may also want to consider consulting a pediatric neurologist. A
neurologist may be able to pinpoint where in your son's body the problem
is. Some SCTs involve the spinal cord. Try to consult a neurologist
before the MRI, to help focus attention of the radiology team on where
to look and what to look for. That will determine technical details
of the scans: which equipment they use, which angles they scan at, etc.

Yes, long periods of wait and see are very stressful. And yes, I will
do all I can just as fast as I can. So will you. This group is here
for people like us.
>I find it strange that the protocl seems to vary so much, it makes it
>hard to know which to go by!
There is no world research group, and all existing protocols are based on
data collected in certain subsets of patients worldwide: United States,
United Kingdom, Germany, Italy... However, the protocols are not very
different from each other. In my daughter's case, it was very much up in
the air whether the best approach should be aggressive chemotherapy and
surgery, or wait and see. Wait and see involved a very long and thorough
MRI of both pelvis and abdomen (basically a double MRI), a very thorough
physical examination, AFP tests weekly then monthly, and close monitoring
by me of her diapers. At the slightest sign of constipation I tended to
have an emotional firestorm. Any change for the worse and we would have
started on the chemotherapy route.
>To be honest i really dont know much about doctors we only ever see
>the surgeon and i have never thought to question that untill now
Before now you never needed to know. We all start out ignorant about so
much. When I was pregnant I thought surgery would end or nearly end the
travail. Only later did I grasp what the AFP testing and followup scans
were for.

Please call the radiology department and discuss this with their scheduling
nurse. MRI can be done on a sick child; it just involves higher risks.
You're better off waiting, unless his limping progresses or any new signs
develop. Remember that for the MRI they'll want an empty stomach etc., so
to get a same day scan you will need to have an idea in advance what time
the scan would occur.

You are very welcome. I am here to help.
