2. Introduction
 Testicular tumors are rare.
 1 – 2 % of all malignant tumors.
 Most common malignancy in men in the 15 to 35 year
age group.
 Benign lesions represent a greater percentage of cases
in children than in adults.
 Most curable solid neoplasm

3. • Age - 3 peaks
2 – 4 yrs
20 – 40 yrs
above 60 yrs
• Testicular cancer is one of the few neoplasms
associated with accurate serum markers.
• Most curable solid neoplasms and serves as a
paradigm for the multimodal treatment of
malignancies.

4. Improvement in Survival
 Effective diagnostic techniques
 Improved tumor markers
 Multi-model treatment
 Surgical
 Radiotherapy
 Multi-drug chemotherapy regimens
 Mortality
 before 1970 – 50 %
 1997 – 5 %

 Sensitive to both
 Radiotherapy
 Chemotherapy
 Differentiation
 Rapid rate of growth
 Young – no co-morbid
 Extra Gonadal Germ Cell Tumors (EGCT)
 Prognosis is ½ GCT

12. Seminoma
 The commonest variety of testicular tumour
 Adults are the usual target (4th and 5th decade);
never seen in infancy
 Right > Left Testis
 Starts in the mediastinum: compresses the
surrounding structure.
 Patients present with painless testicular mass
 30 % have metastases at presentation, but only
3% have symptoms related to metastases

13. • Serum alpha fetoprotein is normal
• Beta HCG is elevated in 30% of patients with
Seminoma
• Classification
a) Typical
b) Anaplastic
c) Spermatocytic

14.  Anaplastic
 5% - 10
 Middle age
 Aggressive - lethal
 Greater mitotic activity
 Higher local invasion
 Higher metastatic potential
 Higher rate of β
 -HCG production
 Inguinal orchidectomy +
Radiation

Old age > 50 yr
Extremely low metastatic potential
Good prognosis
 Typical/ Classical
 82% - 85%
 Middle age
 PLAP – 90%
 Syncytiotrophoblsts – ↑Beta HCG (10%)
 Very slow growth
 Inguinal orchidectomy + Radiation

15.  Macroscopically:
Characterized by a
circumscribed lobular
gray white fleshy
tumor that have areas
of necrosis &
hemorrhage
Cut surface in
homogenous and
greyish white or
pinkish in colour

16. • Microscopically:
Typical seminoma Cells have
round to oval nuclei with
one to several nucleoli &
clear to eosinophillic
cytoplasm.
Cell borders are well defined
arranged in solid nests
separated by fibrous septa.
Active lymphocytic
infiltration in 80% cases.
Strongly positive for
placental Alkaline
phosphatase (PLAP)

17. Embryonal Carcinoma
 2nd most common germ cell tumor
 Present in majority of mixed germ cell tumors
 Most men present in their 20s to 30s with a
testicular mass
 Highly malignant tumours; may invade the cord
stuctures
 High degree of metastasis
 Serum AFP is normal , & beta HCG is elevated in
60 % of cases

18.  Macroscopically:
Tan to yellow neoplasms
(fleshy tumor) that
exhibit large areas of
hemorrhage and
necrosis.
• Most undifferentiated;
capacity to differentiate
to other NSGCT within
primary or mets

19.  Microscopically:
Undifferentiated malignant cells
with crowded pleomorphic
nuclei
Solid sheets,
Papillary
Glandular
Tubular arrangement of cells

20. Choriocarcinoma
 A rare and aggressive tumour (5yrs survival is 5%)
 Typically elevated hCG
 Presents with disseminated disease
 Metastasis to lungs and brain
 Primary is very small and often exhibit NO TESTICULAR
ENLARGEMENT
 Small palpable nodule may be present.
 Prone to hemorrhage, sometimes spontaneous (lungs
and brain)
 Catastrophic hemorrhage immediately after
chemotherapy;

21.  Macroscopically:
Primary lesion may be a
hemorrhagic or a clotted
mass in which bits of grey
tumor can be seen
Presents as nodules
• Microscopically:
Consists of both
syncitiotrophoblast and
cytotrophoblast
Prominent areas of
hemorrhage and necrosis.

22. Yolk Sac Tumour
Most common germ cell tumor ( & most
common testicular tumor ) in children, where
it occurs in its pure form.
In adults, it is unusual in pure form, but is
found approx. 50 % of mixed germ cell
tumors.
Testicular mass the most usual presentation.
Always produce AFP, never hCG
Easily detectable, lower relapse

23. Macroscopically:
White to tan masses, with myxoid & cystic
changes
• Microscopically:
Reticular network of medium sized cuboidal
cellswith cytoplasmic and extracytoplasmic
eosinophil, hyaline like goblets (84%)
Glandular, papillary or microcystic pattern
Schiller-Duval bodies are characteristic

24. TERATOMA
Teratoma in greek means “monster tumor”
Occurs in its pure form with a mean age of
diagnosis at 20 months
In adults, occur as a component of mixed
germ cell tumor & is identified in > 47 % of
mixed tumors.
Pure teratomas are uncommon.
Normal serum markers.
◦ Mildly elevated AFP levels

25.  Macroscopically:
Largely depends on elements within it with solid & cystic areas
 Microscopically:
Contain more than one germ cell layers(ectoderm, endodermand
mesoderm).
Range from “mature” with well differentiated tissue to
“immature” with undifferentiated primitive tisuue.
Composed of somatic type of tissues that include enteric type
glands, respiratory epithelium, cartilage, muscles, hair etc.
Immature Teratomas contain immature neuroepithelium,
blastema or cellular stroma.
Can give rise to carcinoma, such as adenocarcinoma , or
sarcoma, such as rhabdomyosarcoma.

26. • Growing Teratoma Syndrome:
May grow uncontrollably, invade the surrunding
tissueand become unresectable
• Teratoma with malignant transformation
Rarely teratoma may transform into a somatic
malignancy such as rhabdomyosarcoma,
adenocarnoma or primitive neuroectodermal
tumour

27. Cut surface
Variably sized cysts
Gelatinous, mucinous,
hyalinized material
Intersposed solid islands –
cartilage/ bone/pancreatic/
liver/ intesttinal/ muscle/
neural/ connective tissue

29. Secondary Tumors of Testis
• Lymphoma – most common secondary tumor
- most common testicular tumor in patients
above 50 years
- most common variety is histiocytic
• Leukamic Infilteration of testis
-primary site of relapse after ALL remission
-occurs mainly in the interstitial space
-biopsy for diagnosis
- no orchidectomy
- testicular irradiation for treatment
• Metastases to testis
- rare cases reported

30. Tumors of adnexa / Paratesticular
tissue
• Adenomatoid tumor
-most common paratesticular tumor
-benign in nature
• Mesothelioma
-metastatic in 15% cases to inguinal lymph nodes
• Cystadenoma
- bilateral cases are associated with Von Hippel Lindau
syndrome
• Rhabdomyosarcoma
- most commonly seen in second decade of life

31. Intratubular Germ Cell Neoplasia
(ITGCN)
Adjacent to germ cell tumor: 98%
•Cryptorchidism: 2-8%
•Prior germ cell tumor (contralateral testis): 5%
•50% risk of developing GCT in 5y
•Treat with observation, XRT (20 Gy) or orchiectomy
•Chemo reduces risk but still 25% - 45% risk of GCT at 10y
(Christensen et al. Ann. Oncol. 1998)
•Can be precursor to all types of GCT except
spermatocytic seminoma

32. Metastasis
1. Direct Spread:
 This spread occurs by invasion.
 Whole of testis in involved and restricted
 Tunica albuginea is rarely penetrated
 May be crossed by “blunder biopsy”
 Scrotal skin involvement
 Fungation on the anterior aspect
 Spread to spermatic cord and epidedymis may
occur : points towards bad prognosis

33. 2. Lymphatic spread:
Seminoma metastasize exclusively
through lymphatics
They drain primarily to para-aortic
lymph nodes in the region of origin
of tetsticular arteries
Left supraclavicular fossa through
the thoracic duct
Lymph from medial side of testes
run along the artery to the vas to
drain to nodes at the bifurcation of
common iliac
No inguinal nodes until scrotal skin
involvement

34. 3. Blood Spread
 NSGCT spread through blood route
 Lungs, liver, bones and brain are the usual sites
usually involved

35. Chemo and radiation sensitive
Capacity to differentiate
Consistent pattern of metastasis
Ability to produce marker substances (AFP/HCG)
NSGCT: unique potential for teratomatous differentiation
High growth rates 10-30 days
Retroperitoneum is usually the first and only site of metastatic
disease
Landing zones for right-sided tumors: Interaortocaval, precaval
lymph nodes
Landing zones for left-sided tumors: Para-aortic, left hilar
lymph nodes
Right to Left Crossover extremely common
GCT – Unique Features

36. Clinical Features / Presentaion
1. Due to primary tumor
a) Painless testicular lump
b) Sensation of heaviness if size > than 2-3 times
c) Rarely dragging pain is complained of (1/3rd
cases)
d) May mimic epidedymo-orchitis
e) Sudden pain and enlargement due to
hemorrhage mimicking torsion
f) History of trauma (co-incidental

37. 2. Due to metastasis
 Abdominal or lumbar pain (lymphatic spread)
 Mass in epigastrium
 Dyspnoea, hemoptysis and chest pain with lung mets
 Jaundice with liver mets
 Hydronephrosis by para-aortic lymph nodes
enlargement
 Pedal oedema by IVC obstruction
 Troiser’s sign

38. Differential Diagnosis
• Testicular torsion
• Epididymitis, or epididymo-orchitis
• Hydrocele,
• Hernia,
• Hematoma,
• Spermatocele,
• Syphilitic gumma .

39. Investigations
1. USG testes: gold standard
2. Tumor markers/ hormones
a) AFP
b) Beta hCG
3. Chest radiography
4. USG abdomen
5. CT abdomen
6. MRI: intra-abdominal and intra-thoracic
secondaries
7. IVP and RFT : obstruction on ureters

40. Radiological work up
Plain X-Ray
chest:
Metastasis

41. USG :
Hypoechoic
relative to the
surrounding
parenchyma

42. Seminoma
• Seminomas are well defined within the tunica
albuginea and homogeneously hypoechoic

43. Embryonal cell cancers
• Embryonal cell cancers are
heterogeneous.
• The borders of the tumor are
less distinct.
• More aggressive in behavior.
• The tunica albuginea may be
invaded

44. Yolk Sac Tumor
• Imaging findings are
nonspecific,especially in
children, in whom the only
finding may be testicular
enlargement without a defined
mass.

45. Teratoma
• Well-circumscribed complex
masses. a common feature
and may be a
• Cysts are anechoic or complex,
depending on the cyst
contents (ie, serous, mucoid,
or keratinous fluid)

46. • Choriocarcinomas are often
heterogeneous with multiple
internal calcifications present.

47. • Leydig and Sertoli
cell, are generally
well defined and
hypoechoic.
• Calcifications are
frequently
described.

48. Testicular lymphoma
generally appears as
discrete hypoechoic
lesions, which may
completely infiltrate
the testicle &
epididymis

49. “Burned-out" Germ Cell Tumor
• The patient may present with
widespread metastases even though the
primary tumor has involuted.
• These tumors are clinically occult, with
the testis being normal to small upon
palpation.
• These primary tumors have a variable
appearance. They are generally small
and can be hypoechoic, hyperechoic, or
merely an area of focal calcification.

50. Clinical Staging TNMS
• Findings at Inguinal Orchiectomy Histology, size,
extent of invasion, LVI
• •Imaging Chest and Retroperitoneum
• CT scan with IV contrast
• PET CT more accurate for seminoma rather than
NSCGT
• •Serum Tumor Markers AFP, bHCG , LDH

51. Serum Markers
TWO MAIN CLASSES
• Onco-fetal Substances : AFP & HCG
• Cellular Enzymes : LDH & PLAP
AFP - Trophoblastic Cells
HCG - Syncytiotrophoblastic Cells
( PLAP- placental alkaline phosphatase, & LDH lactic
acid dehydrogenase)

52. AFP –( Alfafetoprotein)
NORMAL VALUE: Below 16 ngm / ml
HALF LIFE OF AFP – 5 and 7 days
Raised AFP :
• Pure embryonal carcinoma
• Teratocarcinoma
• Yolk sac Tumor
• Combined tumors,
• AFP not raised in pure choriocarcinoma , & in
pure seminoma

53. HCG – ( Human Chorionic
Gonadotropin)
Has  and  polypeptide chain
NORMAL VALUE: < 1 ng / ml
HALF LIFE of HCG: 24 to 36 hours
RAISED  HCG -
100 % - Choriocarcinoma
60% - Embryonal carcinoma
55% - Teratocarcinoma
25% - Yolk Cell Tumour
7% - Seminomas

54. ROLE OF TUMOUR MARKERS
• Helps in Diagnosis - 80 to 85% of Testicular Tumours have Positive
Markers
• Most of Non-Seminomas have raised markers
• Only 10 to 15% Non-Seminomas have normal marker level
• After Orchidectomy if Markers Elevated means Residual Disease or
Stage II or III Disease
• Elevation of Markers after Lymphadenectomy means a STAGE III
Disease

55. • Degree of Marker Elevation Appears to be Directly
Proportional to Tumour Burden
• Markers indicate Histology of Tumour:
If AFP elevated in Seminoma - Means Tumour has Non-
Seminomatous elements
• Negative Tumour Markers becoming positive on follow up
usually indicates -
Recurrence of Tumour
• Markers become Positive earlier than X-Ray studies

57. LDH HCG
Miu/ml
AFP
Ng/ml
S0 _< N <N <N
S1 <1.5 x N < 5000 < 1000
S2 1.5-10x N 5000 to
50000
1000 to
10000
S3 >10x N > 50000 >10000

59. PRINCIPLES OF TREATMENT
• Treatment should be aimed at one stage
above the clinical stage
• Seminomas - Radio-Sensitive. Treat with
Radiotherapy.
• Non-Seminomas are Radio-Resistant and best
treated by Surgery
• Advanced Disease or Metastasis - Responds
well to Chemotherapy

60. • Transscrotal biopsy is to be condemned.
• The inguinal approach permits early control of
the vascular and lymphatic supply as well as
en-bloc removal of the testis with all its
tunicae.
• Frozen section in case of dilemma

61. Treatment of Seminomas
Stage I, IIA, ?IIB –
Radical Inguinal Orchidectomy followed by radiotherapy to
Ipsilateral Retroperitonium & Ipsilateral Iliac group Lymph
nodes (2500-3500 rads)
Bulky stage II and III Seminomas -
Radical Inguinal Orchidectomy is followed by Chemotherapy

62. Testes sparing surgery
•Controversial
•Mass <2cm
•Simultaneous bilateral tumors
•Solitary testicle with normal
testosterone
•Biopsy adjacent parenchyma (80%
ITGCN)
•Can treat remaining testicle with
20Gy of XRT

63. Scrotal violation
• Local recurrence higher (2.9% vs 0.4%)
(Capelouto et al. J. Urol. 1995)
• •Seminoma – extend radiation portal to
include groin and scrotum area
• •NSCGT – excise scar and cord remnant
• •Extensive groin resection or
hemiscrotectomy not required especially after
chemo

64. Treatment of Non-Seminoma
Stage I and IIA:
RADICAL ORCHIDECTOMY
followed by RETROPERITONEAL LYMPH NODES DISSECTION
Stage IIB:
RPLND with possible ADJUVANT CHEMOTHERAPY
Stage IIC and Stage III Disease:
Initial CHEMOTHERAPY followed by SURGERY for Residual
Disease

67. Lymph Nodes Dissection For Right & Left Sided Testicular
Tumours

68. Lymphatic drainage
• The primary drainage of the right testis is
within the interaortocaval region.
• Left testis drainage , the para-aortic region in
the compartment bounded by the left ureter,
the left renal vein, the aorta, and the origin of
the inferior mesenteric artery.
• Cross over from right to left is possible.

69. Retroperitoneal lymph node dissection
Rationale for RPLND:
The retroperitoneum is the most common site of occult
metastasis
15-25% of retroperitoneal teratoma, resistant to cheotherapy
Low risk of Abdomino-pelvic recurrence no need for long term
surveillance after bilateral RPLND
Offers high cure rates
The long term survival approaches 100% with RPLND +
adjuvant chemotherapy
Disadvantage:
Experienced surgeon
Major surgical procedure

70. STANDARD CHEMOTHERAPY FOR
NON-SEMINOMATOUS GERM CELL
TUMOURS
Chemotherapy Toxicity
BEP -
Bleomycin Pulmonary fibrosis
Etoposide (VP-16) Myelosuppression
Alopecia
Renal insufficiency (mild)
Secondary leukemia
Cis-platin Renal insufficiency
Nausea, vomiting
Neuropathy

71. PROGNOSIS
Seminoma Nonseminoma
Stage I 99% 95% to 99%
Stage II 70% to 92% 90%
Stage III 80% to 85% 70% to 80%

72. Surveillance
 Rationale for surveillance:
70-80% patients of stage I are cured by orchidectomy
alone
No need of chemotherapy in majority of the patients
 The disadvantages being:
Higher risk of relapse
Need for long term surveillance (>5yrs)
Potential for secondary malignancies by surveillance
CT
More intensive therapy required in cases of relapse
than primary chemotherapy
