B/10. Testicular tumors Flashcards
Epidemiology of testicular tumors
- Cancer of young men (age at presentation usually 18-35 years)
- Caucasians > African-American
Cancer of young men
testicular tumors
18-35 years)
Risk factors for testicular tumors
- Cryptorchidism (abdominal cryptorchid testis > inguinal cryptorchid testis) : strongest risk factor
- Family history
- Klinefelter syndrome
- Tumor of contralateral testis
what can reduce the risk of germ cell tumors and improves the ability to save the testis
Early orchiopexy
abdominal cryptorchid testis that cannot be brought into the scrotum should be
removed.
Clinical findings in testicular tumors
- Painless testicular mass in young men is pathognomonic for a testicular malignancy.
- The mass does not transilluminate (differential : hydrocele)
- More commonly, patients present with testicular discomfort or swelling suggestive of
epididymitis and/or orchitis.
In this circumstance, a trial of antibiotics is reasonable - However, if symptoms persist or a residual abnormality remains: testicular US is indicated
differential between hydrocele and testicular tumor
tumor mass does not transilluminate
Testicular tumors diagnostic
- However, if symptoms persist or a residual abnormality remains: testicular US is indicated
- If a testicular mass is detected, a radical inguinal orchiectomy should be performed
- Biopsy is contraindicated!
- serum level of alpha-fetoprotein (AFP), hCG, and LDH should be measured
- CT scan of the chest, abdomen, and pelvis is indicated after orchiectomy
can u take biopsy of testicular lesion?
Biopsy contraindicated!!!!!
labs to be checked in suspicioun of testicular tumor
- serum level of alpha-fetoprotein (AFP),
- hCG, and
- LDH should be measured
When is CT indicated in testicular tumors?
CT scan of the chest, abdomen, and pelvis is indicated
after orchiectomy
If a testicular mass is detected what should be performed?
radical inguinal orchiectomy
Signs and symptoms due to metastatic testicular cancer
- back pain from retroperitoneal metastases,
- dyspnea due to lung metastases (less common), and
- gynecomastia due to tumors producing hCG.
Testicular mass in mass in male above or equal to 50 years should be regarded as
lymphoma until proven otherwise
pathology of testicular tumors
- Germ cell tumors (>95%):
*Seminoma
*Non-seminoma: Endodermal sinus (yolk sac) tumor, Choriocarcinoma, Embryonal carcinoma, Teratoma - Non-germ cell tumors ( < 5%)
*Sertoli cell tumor : Mostly benign
*Leydig cell tumor :Mostly benign
*Testicular lymphoma
Most common testicular tumor
Seminoma
Seminoma prognosis
- Most common testicular tumor (50%)
- Tends to metastasize late, good prognosis
Non-seminoma
- Endodermal sinus (yolk sac) tumor: Tumor secretes AFP, Aggressive
- Choriocarcinoma: tumor secretes beta-hCG, May present with gynecomastia and symptoms of hyperthyroidism
- Embryonal carcinoma : Painful, hemorrhagic mass with necrosis
- Teratoma: Usually malignant (compared with female teratoma)
learn the names onlys in this flashcard
Endodermal sinus
(yolk sac) tumor
is it good or aggressive ?
Tumor secretes AFP
- Aggressive Non-seminoma
non seminoma germ cell tumor
Choriocarcinoma
what does it present with
- tumor secretes beta-hCG
- May present with gynecomastia and
symptoms of hyperthyroidism
non seminoma germ cell tumor
Embryonal carcinoma feature
Painful, hemorrhagic mass with necrosis
non seminoma germ cell tumor
Teratoma
is it malignant or benign?
Usually malignant (compared with female
teratoma)
non seminoma germ cell tumor
Non-germ
cell tumors
(< 5%)
* Sertoli cell tumor Mostly benign
* Leydig cell tumor Mostly benign
* Testicular lymphoma
-Most common testicular cancer in older men
-Not a 1° testicular disease, arises from a metastatic lymphoma (usually diffuse large B-cell)
-Most common testicular cancer in older men
Testicular lymphoma
-Not a 1° testicular disease, arises from a metastatic lymphoma (usually diffuse large B-cell)
is testicular lymphoma usually a primary testicular disease?
Not a 1° testicular disease, arises from a metastatic lymphoma (usually diffuse large B-cell)
Germ cell
tumors
(>95%)
- Seminoma
- Non-seminoma:
*Endodermal sinus (yolk sac) tumor
*Choriocarcinoma
*Embryonal carcinoma
*Teratoma
Staging of testicular tumor is based on
Based on the American Joint Committee on Cancer (AJCC) groups, which
combines TNM stage and
serum tumor marker levels
Staging of testicular tumor
T1 Disease is limited to the testis, epididymis, no LN involvement
T2 Disease is limited to the retroperitoneal (regional) LNs (paraaortic nodes)
T2a Affected LN < 2 cm
T2b Affected LN 2-5 cm
T2c Affected LN > 5 cm
T3 Disease outside the retroperitoneum, involving supradiaphragmatic nodal sites or viscera
(metastases); with moderately to highly elevated tumor markers
Treatment of testicular tumors
- Prior to surgery: sperm cryopreservation
- Radical inguinal orchiectomy
- Adjuvant radiotherapy and chemotherapy
adjuvant Treatment of seminomas
Following radical inguinal orchiectomy
T1, T2, T3
- T1:
*active surveillance OR
*chemotherapy (carboplatin) OR
*Radiation therapy of regional LNs - T2:
*Radiation therapy
*CHEMO: BEP1 (bleomycin, etoposide, and cisplatin) or EP ( etoposide, cisplatin) - T3: chemo (full dose, not adjuvant) +/- resection of any residual disease focus
active surveillance in testicular tumors
Regular follow-up appointments with physical examination,
chest x-ray
, and abdominopelvic CT scan.
Treatment of non-seminoma testicular tumor
- radical inguinal orchiectomy
- adjuvant treatment (after surgery)
adjuvant treatment of non-seminoma stage 1
- Active surveillance or
- RPLND3 ± cisplatin-based chemotherapy
- Chemotherapy: BEP
adjuvant treatment of non-seminoma stage 2
- In patients with normal post-orchiectomy tumor markers: RPLND3 ± cisplatin-based chemotherapy
- In patients with elevated post-orchiectomy tumor markers: chemotherapy with BEP1or EP2
adjuvant treatment of non-seminoma stage 3
Chemotherapy (depending on prognosis):
BEP1 or EP2 followed by evaluation of any residual disease that may require resection
RPLND (retroperitoneal lymph node dissection) what is it
the standard procedure for removal of the regional lymph nodes of the testis (retroperitoneal nodes).
- removes the LNs draining the primary site and the nodal groups adjacent to the primary landing zone.
- The standard (modified bilateral) RPLND removes all node-bearing tissue down to the bifurcation of the great vessels, including the ipsilateral iliac nodes.
- The major long-term effect of this operation is retrograde ejaculation with resultant infertility.
Nervesparing RPLND can preserve anterograde ejaculation in 90% of patients

- severe N/V
Longterm SE of Cisplatin
- nephrotoxicity,
- ototoxicity,
- peripheral neuropathy,

what should be recommended to all patients before treatment of testicular tumor?
Semen analysis
and
cryopreservation
