Background
• Germ-cell tumors (GCTs) are rare, 1% only of solid tumors
• Age of onset (20-40 yrs old) is critical
• Highly curable neoplasms: almost 90% of patients are cured
Low-stage GCTs
• There is no Consensus concerning low-stages (stage and therapy)
• In contrast with what we have reached in advanced disease (IGCCCG, 1997)
Low-stage GCTs (2)
• Prognosis is not the main issue of low-stage disease
• In fact, the global outcome is extraordinarily favorable as nearly 98-99% of low-stages patients are cured
• QoL is the main issue
• QoL depends on: early and late toxicity of treatment and critical age of patients
Non-seminoma stage I
Staging and Therapy
Clinical stage I NS: common landmarks
• Definition No evidence of disease beyond the testis (normal t/2 markers decay following orchiectomy, normal imaging, as recent as possible)
• Cure-rate: 98-99%• 50 - 70% of NS are diagnosed at this stage:
treatment at this stage is crucial for the best global outcome (cure & morbidity) in most patients
• Risk factors: vascular invasion (VI), %ECa, others
Medical Research Council Model (the only validated
predictive model)
• Risk factors: venous invasion, lymphatic invasion, no YST, presence of ECa
• ≥ 3 factors high risk: 20% of patients,50% of them bearing occult metastases
• < 3 factors low risk: 80% of patients, 20% of them bearing occult metastases

Vascular Invasion (as it is!)
• Many reports (nearly 50%) do not contain this information
• There is a discrepancy of about 20% between first diagnosis and central review
• If this information is not reported and possibly reviewed, up to 70% of patients are randomly or wrongly treated in respect of the main prognostic factor!
Decision Making by issues
• Ease of use of therapy (single shot therapy)

Decision Making by issues
• Ease of use of therapy (single shot therapy)
• Complexity of administration
• Simplification of follow-up
• Late relapses
• Early and late toxicities
Follow-up: NS
• No consensus exists
• Schedules tend to be less intensive in case of active treatment
• Follow-up schedule is the treatment when active surveillance is chosen
• Different schedules may give different results

Chemotherapy
Intensive observation anxiety. Full dose chemotherapy for relapsed pts risk of cardiovascular disease and 2° cancer. Greater risk of loss of AE among pts who relapsed and submitted to post-ChT RPLND (2/3)
Avoids chemotherapy in 90% of pN0 patients and in 70% of pN+ patients.Loss of antegrade ejaculation < 2% in “high volume” centres
Toxicity may be severe also following just 1-2 cycles of ChT. Hypothetical risk of cardiovascular disease (2° cancer?).

Lap-RPLND
Lap-RPLND in testis cancer
• Possible applications– As staging and therapeutic procedure (primary or
post-ChT)
• Advantages– Less invasive than open RPLND
• Criticisms– Is it curative? In case of nodal metastasis at staging,
adjuvant chemo is required (more chemotherapy)– Is it cost-effective?

Clinical Stage I Seminoma
• About 15-20% of untreated patients will relapse (usually in the retroperitoneum)
• For more than half a century, RT has been represented the standard treatment
• Traditional adjuvant therapy (PA and iliac RT Dog Leg at 25-30 Gy) reduced to less than 5% occurrence of relapses
Early stage seminoma
• 75-90% of seminomas are diagnosed when at clinical stage I
• Definition: as for Clinical Stage I non-seminoma
• An elevation of AFP is not consistent with a diagnosis of seminoma

Clinical practice change in the last 10 years
• The majority (56%) of canadian practitioners in 2001recommended RT as the best option for stage I seminoma
• By 2006, the majority favors active surveillance
• In UK, a single cycle of Carboplatin is now the most frequently offered treatment modality
(Huddart Clin Oncol (R Coll Radiol) 2006;18:693)
Clinical Stage I Seminoma
• Opportunity of cure for relapsed patients and late effects of radiation lead to new perspectives:
• Omission of therapy following orchiectomy• Modification of RT administration• Adjuvant Chemotherapy

“Effect of radiotherapy volume and dose on secondary cancer risk in stage I testicular seminoma”.Zwahlen DR et Al, Int J Radiat Oncol Biol Phys, 2008;70:853• the secondary cancer risk (SCR) due to para-aortic (PA), dogleg field (DLF),
or extensive field (EF) radiotherapy (RT) at different dose levels for Stage I testicular seminoma
• organ equivalent dose concept with a linear, plateau, and linear-exponential dose-response model
• estimated cumulative SCR for a 75-year-old patient treated with PA-RT at age 35 was 23.3% (linear model), 20.9% (plateau model), and 20.8% (linear-exponential model) compared with 19.8% for the general population
• dependent on the model, PA-RT compared with DLF-RT reduced the SCR by 48-63% or 64-69% when normalized to EF-RT for PA-RT, the linear dose-response model predicted a decrease of 45% in the SCR, using 20 Gy instead of 30 Gy
• the SCR after PA-RT for Stage I seminoma is reduced by approximately one-half to two-thirds compared with DLF-RT; the SCR is expected to be equal or lower with 20 Gy than with 30 Gy
The long-term risks of adjuvant carboplatintreatment for stage I seminoma of the testis. Powles T et Al. Ann Oncol 2008;19:443
• 199 patients with clinical stage I seminoma• 1 or 2 cycles of adjuvant carboplatin as a single agent• follow-up: 0.1-20.1 years (median 9) • no excess mortality compared with the age and sex-
matched UK population with 95% confidence intervals (CIs) on their standardised mortality ratio (SMR) from 0.36 to 1.83
• no significant increase in death from circulatory disease (SMR 1.44; 95% CI 0.39–3.69) or in incidence of second cancers [standardised incidence ratio (SIR) 0.96; 95% CI 0.26–2.45])

THM
• Prognosis of stage I GCTs is excellent when proper treatments are administered
• Modern concepts must include consideration regarding ease of use and complexity of therapy, simplification of f-u, late relapses and toxicity (early and late)
THM: non seminoma
• 3 choices: surveillance, RPLND, adjuvant chemotherapy (2 PEB)
• Beware of VI! (possibly review)
• Consider availability of resources and patient preference
• Consider aspects favoring patients
THM: seminoma
• 3 choices: surveillance, adjuvant radiotherapy (PAS, 20 Gy), adjuvant chemotherapy (CBCDA 7 AUC)
• Data on CBCDA are too early to draw definitive conclusions on long term safety
• Consider availability of resources and patient preference
• Consider aspects favoring patients
