2. Introduction
•
1-2 % of all male malignancies.
•
Most common malignancy in young adult males (aged 15-40 years)
•
2 to 3% Testicular Tumour are bilateral
•
Worldwide Incidence is 1.5/lakh (Globocan 2008)
•
Incidence in India 0.5/lakh (Globocan 2008)
3. Lymphatic Drainage
•
Right testis: along the IVC inter-aortocaval region
pre-aortic & para-aortic lymph nodes, with possible
cross-over within the retroperitoneum
•
Left testis: Preaortic and para-aortic lymph nodes
around the left renal hilum inter-aortocaval nodes
mostly without cross-over
•
Retroperitoneal lymph nodes are located anterior to the
T11 to L4 vertebral bodies concentrated at the L1–L3
level
•
Nodal spread to ipsilateral iliac chain is ~3%
•
Scrotal skin: lymphatics drain into the inguinal and
external iliac nodes.
4. Aetiology of testicular tumour
•
•
Cryptorchidism - 5-fold increase in incidence.
Eutopic (descended) testis-10%
(Pottern et al. J Natl Cancer Inst. 1985;74:377-381; Swerdlow AJ, Higgins CD, Pike MC. Risk of
testicular cancer in cohort of boys with cryptorchidism. BMJ. 1997;314:1507-1511)
•
Family history - increases the likelihood of developing testicular GCT.
[Dieckmann 1997; Chia 2009; Lutke Holzik 2004; Polednak 1996;Westergaard
1996]
5. •
Risk of developing a new contralateral primary tumor - 2%
[Fossa 2005]
•
Subfertility , infertility, and testicular feminization.
[Richiardi 2004; Raman 2005; Møller 1999; Jacobsen 2000; Guazzieri 1985]
•
Marijuana use -- 2 fold increased incidence of NSGCT
[Daling 2009; Trabert 2011]
•
•
•
Altered intrauterine hormonal environment
Immunosuppression
Mediastinal GCTs : more common in Klinefelter’s syndrome patients .

9. Diagnostic and Staging work up
•
Pre-requisites are:
a) History
b) Clinical Examination
c) Radiological procedure - USG / CT ± MRI ± Bone Scan
d) Tumour Markers - β HCG, AFP, LDH
e) Pathology of Tumour Specimen
10. Clinical Features
•
Painless Swelling of One Gonad
•
Dull Ache or Heaviness in Lower Abdomen
•
Acute Scrotal Pain-10%
•
Present with Metatstasis -10%
- Neck Mass / Cough / Anorexia / Vomiting / Back Ache/ Lower limb
swelling
•
Gynecomastia- 5%
•
Rarely - Infertility
Dictum For Any Solid Scrotal Swellings: All patients with a solid, Firm
Intratesticular Mass that cannot be Transilluminated should be regarded as
Malignant unless otherwise proved
11. ultrasound – B/L testis- confirms a solid testicular mass.
CT scans of the abdomen and pelvis with chest imaging by either CT or
standard x-ray.
• Lymph nodes measuring > 5 mm in a landing zone are suspicious for
metastatic disease in a patient with a known testicular tumor.
MRI:
• If iodinated contrast dye is contraindicated
• Useful for defining vascular anatomy before surgical management of
bulky retroperitoneal masses
12. Bone scan and brain imaging (CT or MRI) are not part of routine staging.
Positron emission tomography (PET) -not useful in routine staging.
•
Neither small lesions nor teratoma can be identified by PET (false
negative) and inflammatory processes such as sarcoidosis often
demonstrate fluorodeoxyglucose avidity (false positive).

21. MANAGEMENT
Sperm banking must be discussed with the patients before undergoing any
therapeutic intervention that may compromise fertility including RT ,Surgery
and CT.
Management of testicular tumor is combined modality treatment.
Various treatment modalities are:
•Surgery
•Surveillance
•Radiotherapy
•Chemotherapy
22. Surgery
Radical orchidectomy:
• All patients
• done via an inguinal incision, with cross
clamping of spermatic cord vasculature and
delivery of testis into the surgical field.
• Scrotal violation, increased local/regional
recurrence, but no difference in distant
recurrence rate or overall survival.
23. Stage wise management of seminoma
Stage I
• Surgery
surveillance
radiotherapy
chemotherapy
24. Surveillance
• Indication: Pts. who can comply.
• Sites for relapses
– Retroperitoneum- 76-94%
– Mediastinum- 5-15%
– Inguinal-3-11%
26. Prognostic Factors for Relapse in Stage I Seminoma
Managed by Surveillance: A Pooled Analysis
•
Pooled Data of 638 patients(Princess Margaret Hospital, Danish Testicular
Cancer Study Group, Royal Marsden Hospital, and Royal London Hospital)
• Median follow-up -7.0 years
• Multivariate predictors for relapse:
1) tumor size > 4 cm and
2) invasion of rete testis
– If tumor < 4 cm then age less than 30 independent risk factor
•
Risk of relapse - no risk factors: 12%; one risk factor: 16%; both risk
factors: 31%
– If tumor < 4 cm, risk relapse if > 30 yo: 11%; if age < 30 yo: 20%

Historically, seminoma was treated with orchiectomy + inguinal/paraaortic RT, and sometimes also mediastinal RT
Prophylactic mediastinal RT was abandoned due to increased cardiac
mortality in the 1960's and 1970's
Para-aortic fields plus ipsilateral iliac LNs ("dog leg") at 30/15 became
standard

–
–
–
–
H&P, labs (AFP, b-HCG, LDH), and CXR every 3–4 months for year 1,
every 6 months for year 2,
then annually,
Pelvic CT annually for 3 years for patients treated with PA-only RT (not
needed if PA and pelvic RT)
59. Stage wise management of Non-seminoma
STAGE I
Post orchidectomy options are:
• Surveillance
• RPLND
• Chemotherapy
60. Stage I
•
•
STAGE 1 (50%)
Survival close to 100%
• Risk factors for relapse
• Venous invasion
• Presence of undifferentiated elements
• Absence of yolk sac elements
• Surveillance
– Follow up tumor markers, phy examination, cxr monthly 1 yr, 2m – 2 yr, 3m – 3 yr,
6m – 4&5 yr.
– CT abd & pelvis monthly for 1 yr, 4m – 2 yr , 6m – 3 yr, yearly 4- 5 yr
61. •
RPLND is offered to stage I nonseminoma patients :
1. with LVI in the primary tumor
2. to noncompliant patients
• The presence of (LVI), is associated with a 45% to 55% of recurrence vs
15% to 20% for patients without this risk factor
•
[Colls 1999; Daugaard 2003; Gels 1995]
62. Retro peritoneal lymph node
dissection(RPLND):
• Include the precaval, retrocaval,
paracaval, interaortocaval, retroaortic,
preaortic, para-aortic, and common iliac
lymph nodes bilaterally.
Disadv.:
• Retrograde ejaculation.
• With modern nerve-sparing techniques,
the incidence has declined to rates of 5%.
Stephenson Aj et al Curr Treat Options
Oncol. 2005;6:367-377.
63. Adjuvant chemotherapy for stage I NSGCT
• Failure of postorchiectomy markers to normalize (stage IS) indicates
the presence of systemic disease, often outside the
retroperitoneum and requires primary management with systemic
chemotherapy.
[Davis 1994]
•
Trials evaluating 1 or 2 cycles of bleomycin, etoposide, and cisplatin (BEP)
in all T2N0-T4N0 demonstrated continuous disease-free survival and
overall survival rates of 95% and 99%, respectively

†Trial performed exclusively in nonseminoma, intermediate-risk patients.
66. Stage I patients are subdivided into low risk, (20% relapse rate) or high risk,
(40–50% relapse rate), according to absence or presence of vascular,
(lymphatic or venous) invasion.
67. Salvage Chemotherapy
•
20% to 30% of patients will develop progressive disease following initial
chemotherapy with or without surgery and will require salvage therapy
•
Conventional doses of cisplatin plus ifosfamide plus either vinblastine
(VeIP) or paclitaxel (TIP) are the most commonly used regimens.
69. Complications : Radiotherapy
•
•
•
•
•
Acute--nausea, vomiting, diarrhea
Late--small bowel obstruction, chronic diarrhea, peptic ulcer disease
(<2% with <35 Gy)
Second cancers: 5–10% increased risk
With testicular shielding, most patients will have oligospermia by 4
months that lasts ~1 year
Infertility: 50% of patients have subfertile counts on presentation or after
surgery. After RT, 30% able to have children
70. Conclusion
Most common curable malignancy of young adults.
Seminoma > nonseminoma
Surgery is the main modality of treatment followed by Radiotherapy & or
chemotherapy for seminoma and chemotherapy & RPLND for
nonseminoma.
Surveillance for patients who are compliant
Follow-up is recommended to detect second primary tumors, local or
distant recurrences, and to monitor for potential long-term side effects
