Testicular Cancer Flashcards
Biggest risk factor for testicular cancer
Cryptorchidism
Genetic aberration commonly seen in testicular GCTs?
Isochromosome 12p
For mixed GCT, at what percentage of nonseminomatous pathology has to be present for the tumor to be classified as a nonseminoma?
1%.
Any amount of nonseminoma means it’s classified as nonseminoma
What STM is not produced by seminoma?
AFP
Half life of AFP
7 days
Half life of bHCG
3 days
Extremely high levels of bHCG, what cancer is that suggestive of?
Choriocarcinoma
Who should get brain MRI?
Predominance of choriocarcinoma
Extensive lung mets
Mets to organs other than lungs
Super high hCG or AFP
STM staging S1
AFP <1000
bHCG <5000
LDH <1.5x ULN
STM staging S2
AFP 1000 - 10,000
BHCG 5,000 - 50,000
LDH 1.5 - 10x ULN
STM staging S3
AFP >10,000
BHCG >50,000
LDH >10x ULN
What are risk factors for recurrence
Embryonal
LVI
What is special about the treatment of stage IS?
Treated like Stage III
Tany N0 M0 S1-3
Elevated STM after surgery means there’s likely disseminated disease
Mets to what location have a better prognosis?
Lungs
What makes disseminated seminoma intermediate risk?
Mets to site other than lungs
***STMs do not play a role
What makes disseminated seminoma poor risk?
Doesn’t exist
What are features of good risk nonseminoma? (2)
Mets to nodes and/or lungs
S0-1
What are features of intermediate risk nonseminoma? (2)
Mets to nodes and/or lungs
S2
What are features of poor risk nonseminoma? (3)
Primary site in mediastinum
Mets to organ other than lungs
S3
3 treatment options for Stage I seminoma?
Surveillance (relapse 17%) - preferred
2 cycles carboplatin (relapse 2%)
RT to RP (relapse 4%)
What is a predictive value of relapse for stage I seminoma? (2)
Larger tumor
LVI
Treatment options of stage I nonseminoma (3)
Surveillance (relapse rate 26%) - preferred
RPLND (11%)
BEP x1 (2%)
What makes up stage I testicular cancer?
T1-4, N0, M0
Limited to testis, spermatic cord, scrotum
What makes up stage II testicular cancer?
RP Nodal disease
Any T, N1-3, M0
STMs S1-2
What staging criteria can change the treatment of stage II patients?
Node size.
Nodes >3 cm get chemo like stage IIIA
<3 cm can get chemo or RT or RPLND
Treatment for Stage IIA or IIB seminoma (4)
RT
BEP x3
EPx4
RPLND - only for nodes <2 cm
What is the distinguishing features of stage IIA/IIB?
LNs <3 cm
What is the preferred treatment for stage IIB/IIC seminoma? (2)
BEPx3
EPx4
Treatment for Stage IIA nonseminoma with S0? (3)
RPLND
BEP x3
EP x4
Patient with stage II NSGCT who undergoes BEPx3 and has residual mass after chemo. What now?
RPLND
Treatment for Stage II nonseminoma with S1 (2)
BEP x3
EP x4
Patient with Stage IIA with S0 nonseminomatous GCT. Undergoes RPLND and has found to have 2 LNs positive for malignancy. Anything else to do to lower relapse risk?
2C of EP
can do 2C of BEP but not preferred
Treatment for Stage III good risk seminoma? (2)
BEP x3
EP x4
Three characteristics to make you consider EPx4 instead of BEP x4
Over age 50
poor renal function
COPD
Treatment for Stage III good risk nonseminoma? (2)
BEP x3
EP x4
Treatment for Stage III intermediate risk seminoma?
BEP x4
VIP x4
Treatment for Stage III poor risk nonseminoma?
BEP x4
VIP x4
2L chemo for relapsed disseminated disease (3)
VeIP
TIP
Carbo + Etop
Which patients are at highest risk for VTE. What to do about it?
large RPLNs
Prophy DOACs
in addition to pneumonitis, what other lung changes can bleomycin cause?
Pseudonodules. Inflammatory, not progression
Patient with Stage III NSGCT undergoing BEP. STMs are responding but tumor is enlarging. What is going on and what do you do?
Growing teratoma syndrome.
Surgery
Patient with intermediate risk Stage III NSGCT with lung mets undergoes 4C BEP and STMs have normalized, and imaging shows resolution of lung mets, but persistent PRLNs. He undergoes RPLND with 2 cm LNs with residual nonseminoma. What to do?
2 cycles of chemotherapy
(TIP, VeIP, VIP, EP)
Treatment of primary mediastinum seminoma with no disease elsewhere? (2)
EP x4
BEP x3
Patient with good risk Stage IIIS Seminoma undergoes BEPx3. His previously seen lung mets resolve but has persistent RPLNs on imaging. STMs have normalized. What to do? (2)
Surveillance
PET/CT. If positive, then resect or biopsy. If resected, then can give 2C of additional chemo if biopsy positive.
