Bone marrow aspiration to confirm diaganosis
What CBC abnormalities can be present with ALL
Anemia
Thrombocytopenia
Predominance of BLasts
WBC NR or slightly elevated (with blasts)
What is the tx for ALL

What is the 5 year survival rate of ALL
>85%
What is the second most common childhood cancer
CNS tumors
What are the s/s of CNS tumors
HA
N/V
Ataxia/impaired gait
Impaired vision
Sz
Papilledema
When would macrocephaly be a sign of CNS tumor
If the pt is young enough that their cranial sutures haven’t closed
How do you dx CNS tumors
MRI is preferred but Bx is needed to make a histological diagnosis
What is the tx for most CNS tumors
Open surgical procedure -→also necessary for obtaining dx
Sometimes will give chemo and anticonvulsants for sz
What treatment for CNS tumors is typically avoided in kids
radiation therapy
What is the prognosis for CNS tumors
Depends on tumor type- overall 5 year survival rate is about 75% but there are common long term sequelae associated with it

How often is retinoblastoma bilateral
⅓ of the time and more commonly in heritable forms
What is the first thing you should do if you suspect retinoblastoma
refer the pt to optho
What is recommended testing for all pts with retinoblastoma
molecular genetic testing
What is the tx for retinoblastoma
cryotherapy
local or systemic chemo
laser photocoagulation
enucleation
radiation
What is the surivial rate for pts with retinoblastoma
>95% survival rate if caught and addressed within one year
What puts a pt at risk of osetosarcoma
most of the time it is sporadic but can be at higher risk if:
Prior radiation or chemo
genetic
paget disease
male
What are the s/s of osteosarcoma
