Men with cryptorchidism are _______ times more likely to be diagnosed with testis cancer in the affected gonad, but the relative risk falls to _______ if orchidopexy is performed before puberty
A) 3 to 4, 2 to 3
B) 4 to 6, 2 to 3
C) 6 to 8, 3 to 4
D) 5 to 10, 3 to 5
B. 4 to 6, 2 to 3
TRUE or FALSE: In a unilaterally cryptorchid patient, the contralateral descended testis is also at increased risk for testicular cancer
TRUE
The following statement about germ cell neoplasia in situ (GCNIS) is FALSE
A. All germ cell tumors (GCT) arise from the precursor lesion GCNIS.
B. GCNIS is present in the adjacent testicular parenchyma in most cases of invasive GCT.
C. Some of the patients with GCT have GCNIS in the contralateral testis.
D. Microlithiasis in the contralateral testis of men with GCT may indicate the presence of GCNIS
A. All germ cell tumors arise from the precursor lesion GCNIS
TRUE or FALSE: 5% of postpubertal GCTs are extragonadal in origin, arising in the retroperitoneum and mediastinum.
TRUE
The inferior mesenteric artery is ligated during a RPLND for testis cancer. Blood supply to the sigmoid colon is now derived from which artery:
A. Right colic
B. Superior hemorrhoidal
C. Middle sacral
D. Middle hemorrhoidal
E. Sigmoidal
D. Middle hemorrhoidal
TRUE or FALSE: Germ cell tumors containing seminomatous and non-seminomatous components are classified as non-seminomatous germ cell tumors.
TRUE
TRUE or FALSE: For testicular neoplasms, the risk of malignancy increases with the size of the lesion
TRUE
TRUE or FALSE: Among men with cryptorchidism, the contralateral descended testis is also at risk for developing testicular cancer.
TRUE
Up to ___% of seminomas secrete HCG, but levels are most often < ___ IU/L.
A. 15%, 5000 IU/L
B. 15%, 10,000 IU/L
C. 5%, 15,000 IU/L
D. 5%, 2000 IU/L

D. Bleomycin, Etoposide, Cisplatin (BEP)
D. Bleomycin, Etoposide, Cisplatin (BEP)
TRUE or FALSE: Most non-seminomatous germ cell tumors occur as pure forms, with a specific subtype existing alone.
FALSE
The typical GCT has this echotexture:
A. Hypoechoic; with heterogenous texture more common with NSGCT, and homogenous with seminomas
B. Hyperechoic; with heterogenous texture more common with NSGCT, and homogenous with seminomas
C. Hypoechoic; with heterogenous texture more common with seminoma, and homogenous with NSGCT
D. Hyperechoic; with heteroge
A. Hypoechoic; with heterogenous texture more common with NSGCT, and homogenous with seminomas
The parameters considered in the International Germ Cell Cancer Collaborative Group (IGCCCG) risk classification for advanced NSGCT include the following, EXCEPT:
A. Site of primary tumor
B. Non pulmonary visceral metastasis
C. Lymphovascular invasion
D. Serum tumor markers
C. Lymphovascular invasion
TRUE or FALSE: Choriocarcinoma and seminomas do not generally produce AFP. And AFP may be falsely elevated in some cancers, such as cancers of the liver, stomach, pancreas, and lung.
TRUE
