-age <1 or 10+
-wbc > 50k
-presence of CNS 3 or testicular dx
-mrd > 0.01% on day 8 AND at end of induction (day 29) (B cell)
-mrd >0.1 end of consolidation (T cell)
-t-cell lineage
-steroid pre-treatment
*very high risk features: >13y, BCR-ABL, KMT2A, hypodiploidy (<44), induction failure (>5-25% blast at end of induction)
*good risk features: double trisomies 4 and 10, ETV-RUNX1
Pediatric medulloblastoma average vs high risk
Average:
-3+ y
-<1.5 cm residual tumor
-M0
-not anaplastic
High risk:
-<3 y
-1.5+ cm residual tumor
-Metastatic
-anaplastic
Neuroblastoma MS (aka 4S)
Metastatic dx in children <18 months with Mets confined to skin, liver, and/or bone marrow
Observation. Most spontaneously regress with favorable genetics (below):
-<10% malignant cells in BM
-no MYCN or 11q aberration
Treat as high risk if unfavorable genetics
Define high volume prostate CA (when we add docetaxel)
Visceral Mets or 4+ bone Mets (at least 1 outside vertebral column/pelvis)
What grade is high grade serous ovarian cancer?
Grade 2-3
Group A (low risk) pediatric Burkitts
Completely resented stage I and abdominal stage II
Group B (intermediate) pediatric Burkitts
-mx extra abdominal sites
-non-respected Stage I-IV
-marrow blasts <25%
-no CNS dx
Group C (high risk) pediatric Burkitts
->25% marrow blasts and/or CNS dx
Khorana score
2+: DVT ppx x6 months
<2: no DVT ppx needed
xarelto 10 mg QD or eliquis 2.5 mcg BID
2pts: stomach or pancreatic cancer
1pt: lung, gyn, testicular, bladder, lymphoma, plt >350, Hgb <10 or ESA, leukocyte >11, BMI 35+
Note: not used for MM, acute leukemia, myeloproliferative neoplasms, primary/metastatic brain tumors
Impede/saved scores
For AC in multiple myeloma pts
-saved is for pts on IMiDs and impede is for MM pts in general
-impede 1-3, saved <0-1: daily Asa
-impede 4+ or saved 2+: AC
Lovenox 40 QD, dalt 5000 Iu QD? warfarin, Apix 2.5 BID, xarelto 10 QD, fondaparinux 2.5 qd
don’t need ppx in IMiD maintenance
HR positive vs negative
HR negative: Stain <1% HR receptors
HR positive: stain 1-100%
*1-10% still get endocrine therapy but likely less benefit
HER2 postive vs negative
Negative: IHC 0, IHC 1, IHC 2 and fish negative
Positive: IHC 3, IHC 2 and fish positive
Who qualifies for breast cancer gene expression assays?
Post-menopausal or >50y, HR+, HER-2-, LN negative or 1-3 LN +
-Can also use OncotypeDx in premenopausal if they meet above criteria and LN negative
-prosigna only for LN negative
T3 (>5 cm) will need chemo so don’t bother with assay
Note: oncotype is prognostics AND predicative
How is HER-2 low defined
HER IHC 1+ or 2+ FISH negative
Define aggressive variant prostate cancer
Fill in this answer
Breast cancer pN1
1-3 LN +
If n2 or more this means >4 LN
Definition of AML
> 20% blasts
Philadelphia chromosome
t(9;22)
Hallmark of APL
Blasts with t(15;17)
Core binding fx (AML)
inv(16), t(16;16), t(8;21)
add Gemtuzumab ozagamicin (don’t need CD33+ listed)
This is actually favorable risk (as is t(15;17)- so would NOT consolidate with HCT

High: wbc>10k
Note: APL is M3 subtype of AML
NMIBC risk stratification
Low risk:
