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

Page 3: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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)

Page 4: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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

Page 6: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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

Page 7: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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!

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

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

Page 59: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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)

Page 63: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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])

RT: PAS Vs DL

Advantages DisadvantagesReduction of acute toxicity

Earlier recovery of fertility

Simplification of treatment

Increase of pelvic recurrences (right)?

Does a risk of late toxicities remain?

RT: 20 Gy Vs 30 Gy

Advantages DisadvantagesEarly physical recovery

Reduction 2° cancer (?)

Increase of recurrences (nonpelvic)?

Does a risk of late toxicities remain?

Carboplatin Vs RT

Advantages DisadvantagesReduction of GI tox Increase of hematological tox

Earlier physical recovery Increase of retroperitoneal relapses (?)

Reduction of 2° cancer risk (?) Too few data and too early for evaluation

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)

Page 76: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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

Page 77: Sc Urologia Italian Germ-cell cancer Study Group Controversies in treatment and surveillance of clinical stage I seminoma and nonseminoma testis cancer

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
