RATIONAL TREATMENT DELIVERY IN
CLINICAL STAGE I AND II TESTICULAR
GERM CELL TUMOURS (INCLUDING
LONG-TERM TOXICITIES)

most countries worldwide, more markedly in Southern Europe and Latin America.
Mortality from TC shows a different pattern, with higher rates in some countries of
medium to high Human Development Index (HDI)….’

SHIFTING CLINICAL PRESENTATION
OF TESTICULAR GERM CELL TUMOURS
Reprinted from Urol Oncol, 2014: 32 (1) Ruf CG, et al., Changes in epidemiologic features of testicular germ cell cancer: Age at diagnosis and relative
frequency of seminoma are constantly and significantly increasing, 33.e1-33e6. Copyright 2014, with permission from Elsevier
Rajpert-De Meyts E, et al., Lancet 2016; 387(10029):1762-1774
Roughly 75% of all testicular germ cell tumours (80% of seminomas and 60% of
non seminomas) are detected in clinical stage I
Orchiectomy alone cures 80% of seminomas and 70% of non-seminomas, and
standard care has increasingly shifted to active surveillance
Patients with CSI seminomas have a 13–19% rate of relapse
Primary pathological risk factors are poorly defined
Patients with CSI nonseminomas have a 30% risk of relapse, which may
necessitate treatment
However, one key risk factor (LVI) has been defined

Treatment options for CSI testicular germ cell tumours are patient-driven
Informed consent on each therapeutic strategy cannot leave out patients’ expectancies
Do not forget that treatment options, whether they are risk-adapted or not, are equal for
clinicians, not for patients
CSI patients have a good probability to be cured just after orchiecotmy, BUT surveillance
does not only mean ‘not to treat’
“Patient empowerment” can make a difference in CSI testicular germ cell tumours
‘PATIENT EMPOWERMENT’
DILEMMAS IN CLINICAL STAGE II (IIA/B) TESTICULAR GERM CELL TUMOURS
Non-seminoma: the dilemma in clinical Stage II
(Clinical Stage IIC (adenopathy >5 cm) should follow the therapeutic
algorithm of metastatic disease)
The appropriate primary intervention for CS IIA (adenopathy 2 cm) or IIB
(adenopathy 2 to 5 cm) remains controversial
Retrospective series of patients with CS II NSGCT treated primarily by
chemotherapy or retroperitoneal lymph node dissection (RPLND) have reported
survival rates greater than 95%
The decision to treat patients with CS II NSGCT initially with either RPLND or
cisplatin-based chemotherapy depends primarily on the following issues:
Extent of disease
Burden of retroperitoneal disease (single vs. multiple enlarged lymph-nodes)
Greatest node diameter (MSKCC 3 cm cut-off)
STM status post-orchiectomy
CLINICAL STAGE II TESTICULAR
GERM CELL TUMOUR – NONSEMINOMA
Not all small volume CT changes do represent disease
10-40% of patients are pathological stage I (uninvolved lymph-nodes)
Differentiation between inflammatory LN and metastatic LN is difficult
Benefit from PET for detection of occult metastases is modest
Small volume radiographic changes (<2 cm) should be confirmed by
follow-up CT in 2-4 months before starting therapy

Rate of teratoma in the primary
tumour (up to 82% of teratoma in
residual mass after
chemotherapy)
Teratoma (22% in CSIIA),
malignant GCT, and malignant
non-GCT in RPLND (35.7%

with TMT)

The presence of elevated pre-RPLND STM was associated with a 5.6-fold increased
risk of systemic relapse and was the most significant predictor of relapse after
primary RPLND

CLINICAL STAGE II NONSEMINOMA
The case of Adjuvant chemotherapy
The role of adjuvant chemotherapy after RPLND in patients with PN1-2 disease is
somewhat controversial
The randomised Testicular Cancer Intergroup Study showed that in patients with PS II
NSGCT, 2 cycles of adjuvant chemotherapy significantly reduced the risk of relapse
after RPLND compared to observation (6% vs. 49%), although there was no overall
survival difference
(1/3 of patients had +ve STM after orchiectomy)

ONGOING STUDIES
Both chemotherapy and radiotherapy did provide excellent results in Stage IIA and
IIB seminoma, and sustained at long term
However, in testis cancer details of pros & cons for each therapeutic option do
matter
These details would favour the use of standard cisplatin-based chemotherapy for
CSIIB patients, while for CSIIA chemotherapy and radiotherapy are equal options
HOWEVER:
These patients exhibit a very good prognosis overall, and 3 cycles of BEP
chemotherapy are being increasingly thought to be an overtreatment
Consequently, attempts to mitigate the long-term side effects of chemotherapy and
to reduce radiotherapy field and doses are warranted
With this aim, the combination of carboplatin and involved-nodes RT is rationale in
selected patients and should be pursued
