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’

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

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

malignant GCT, and malignant

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)

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
