Q

diagnosis of ALL

A

def: BM biopsy (>20% blast cells)and sent off for cytology
FLOW CYMETRY :CD19 B CD 7 T CELLS
CBC: can have pancytopenia but usually its 2 cell lines down like platelets + abc and in rare cases just 1 cell line
blood smear - blast cells
tumour lysis syndrome - high k+ etc
Chest x ray - mediastinal mass
LP - check cNS involvement

abdominal us - check for Organ infiltration

  2. sporadic variant
  3. immunodeficinecy- hIV

clinical staging and pathological staging and patholoigcal reuqires. laportomy and splenectomy

20

WHICH IS MORE COMMONE OS OR EWINGS

boes affected

A

bones
osteosarcoma

OS: bones that form the knee and upper limb (proximal humerus)
EW: pelvis, ribs and tends to be more the diaphysis of bones but can be metaphysis

24
Q

origin of neuroblastoma

prognostic factors

A

adrenal glands, ut can start from other areas of body like sympathetic ganglia near the spine or abdomen

AGE IS VERY IMPORTANT, the younger the child the better <18 months old

25
Q

key word for diagnosis of ewings

A
swollen abdomen 
brushing around the eyes+dancing eyes
horners syndrome
bluish skin nodules (infants)
bone pain 
diarrhoea!
SYMPATHETIC: SWEATING, HYPERTENSION!

onion skin or ‘hair on end’ pattern on x ray, and small blue cell tumours

26

what type of anmeia associated with NH L

types of benign bone tumours

A

NORMOCYTIC

osteoblastoma
osteochondroma
osteiod osteoma
osetoma
chrondroma
giant cell tumour

27
Q

most common symptom of bone cancer

A

HIGH LDH
URIC ACID CAN BE HIGH
NOROMOCYTIC ANEMIA

bone pain

28
Q

what could cause raised copper levels, bone canceres coomonly metastisised too?

A

LYMPHOMAS

leukemias, RA , hemachromatosis

lUNGS, then bone

29
Q

colon cancer marker

tx for neuroblastoma

A

CEA

surgery if it hasnt spread anywhere and chemo if spread or even before surgery to shrink the tumours

RT too

30
Q

diagnosis of neurobkastima

dx of osteosacroma

A

NSE

ewings sarcoma - more likely to hvae raised ESR, LDH , fver anemia

chrondrosarcoma (more in adults)
