2. a model for a curable neoplasm Whilst this group of tumours do as often quoted as a model of a curable neoplasm emphasis particularly in this age group has to be given to reducing need for treatment in those who do well and thus sparing long term effects and increasing cure rates for those few that fall into a bad prognostic group.
Although we talk about testicular cancer these tumours are derived from primodial germ cells and thus the term germ cell caner should be strictly speaking applied.
This explains why they can occur anywhere in the body but usually in midline; sacrum, retroperitoneal, mediastinal, pineal region and in females and with a variety of different cell types.

Biologically the germ cell cancer occurring in young males may be slightly different from those of older men as they often lack the iso-chromosome on short arm of chromosome 12
Micro satellite instability is associated with shorter time to recurrence and platinum resistance

Parenchymatous
16. CONTRALATERAL TESTIS Ideally: biopsy at time of orchidectomy, with aim of
diagnosing carcinoma-in-situ
if carcinoma-in-situ present, discuss prophylactic RT, since at least 50% risk of developing invasive cancer in subsequent years
If not done initially, consider biopsy in stage I patients
on surveillance only
with history of maldescent

23. STAGE I SEMINOMA Standard of care is adjuvant radiotherapy 30Gy to dog-leg field (Fossa, 1999)
Questions:-
Can the dose of radiotherapy be decreased to lessen acute toxicity without increasing relapse?
As the excess risk of second malignancy after XRT is well described, is chemotherapy a valid alternative? MRC level Ib evidence; 3y survival 99-100%
2-3-fold excess relative risk
MRC level Ib evidence; 3y survival 99-100%
2-3-fold excess relative risk
24. STAGE I SEMINOMA Answers:-
Yes, decreased dose of radiotherapy to 20Gy is not associated with increased mortality and reduced albeit low GI toxicity and fatigue (MRC Trial TE18, Jones et al, 2001)
Single cycle of Carboplatin AUC7 is as efficacious as radiotherapy, less acute toxicity and faster return to work (Oliver, Lancet, 2005. 366(9482): p. 293-300)
What about surveillance?
Subject of TRISST study TE18 Level Ib; MRC trial of 600pts
Other studies have looked at 2 cycles of lower dose carboplatin
Risk of relapse up to 30 % if rete testis involved and > 4 cm primary around 15 % for one factor
Use of surveillance has been extensively performed by the Canadians.
A recent paper for give guidance for the frequency and type of imaging to be used in follow- up according to the adjuvant strategy applied i.e. a risk adapted strategy to minimise the exposure to radiation etc.

26. STAGE I TERATOMA Confined to testis, normal markers, no metastases
High and Low risk groups defined by assessment of extent of vascular/lymphatic invasion:-
Reduces risk of recurrence from 45% to around 2%
No level I evidence for BEP x2 but unlikely to impact on OS rates
Reduces risk of recurrence from 45% to around 2%
No level I evidence for BEP x2 but unlikely to impact on OS rates
27. STAGE I TERATOMA Questions:-
Can the risk of second malignancy from CT scans be abrogated without increasing relapse rate in low-risk patients?
Can the toxicity of chemotherapy (BEP) be decreased in high risk patients?
Is there a more sensitive way of defining high-risk patients to avoid chemotherapy for all?
RPLND?
28. STAGE I TERATOMA Answers:-
Trial CT of scan frequency in low risk patients (TE08; 2 vs 5 scans in 2 years) CTs at 3 and 12 months only now standard of care (Rustin JCO, 2007. 25(11): p. 1310-5)
BOP (substitution of etoposide by vincristine) has ? toxicity, similar progressions
(Dearnaley BJC, 2005. 92(12): p. 2107-13)
PET scan study in high risk patients (TE22) closed early due to a lack of ability for PET to predict relapse
(Huddart JCO, 2007. 25(21): p. 3090-5)
Current 111 trial 1 BEP for high risk stage I NSGCT
RCT RPLND vs BEP x 1 surgery significantly higher RR, ? 2 year survival rate, hazard ratio for recurrence
(Albers, JCO 2008 26, 2966-72)
The substitution of vinc for etoposide there was no difference in relapse rate, less alopecia but more neuropathy
Primary: to show that one cycle of adjuvant BEP chemotherapy results in a two year recurrence rate of less than 5% in patients with high-risk stage 1 NSGCTT.
236 patients will be recruited into this study.
Etoposide does is 500 mg/m2
All patients will be given prophylactic GCSF; either pegylated G-CSF 6mg subcut on day 4 or filgrastim daily sc according to local policy. All patients will be given prophylactic antibiotics; either levofloxacin 500mg po (recommended) on days 8 to 15 or ciprofloxacin 500 mg bd on days 8 to 15.

34. GOOD PROGNOSIS TERATOMA BEP x 4 is standard regimen (Williams et al, NEJM 1987, 316:1435-40) and cures 96% patients in this subgroup.
Questions:-
How many cycles are required (i.e. reduce toxicity esp 2nd malignancy from etoposide)?
Can we omit bleomycin without compromising efficacy?
Can we substitute carboplatin for cisplatin (and therefore make it easier for the patient)?

41. GOOD PROGNOSIS Bottom line 3 BEP is treatment of choice.
4 EP may be used in this prognostic group, but ONLY if significant concern over pulmonary function
The evidence suggests that carboplatin should not be routinely used in place of cisplatin.
Next questions:-
Reduce to 2 BEP?
Reduce bleomycin lung toxicity by changing schedule/route of administration ongoing TE03 study
good prognosis metastatic germ cell cancer the current randomised Phase III study run by the NCRN Testis Clinical studies Group is TE03 comparing infusional bleomycin on day 1-3 and the standard bolus regime on day 2, 8 and 15 .
The primary end-point is the radiological evaluation on CT of potential bleomycin induced lung changes with follow up to see if there is any difference in long term pulmonary toxicity as there is phase II data suggesting that infusional bleomycin will cause less pulmonary toxicity.

43. INTERMEDIATE RISK BEP x 4 is standard regimen (Williams et al, NEJM 1987, 316:1435-40) and cures up to 70% patients.
Questions therefore concern ways to increase efficacy, rather than decrease toxicity:-
Add/substitute different drugs e.g. ifosfamide, Taxol?
EORTC T- BEP x 4 vs BEP x 4 - suspended
4 VIP vs 4 BEP cure rates = ? toxicity with VIP
(de Wit BJC 1998 78(6) 828-826)

NCRN Accelerated BEP with 2 weekly cycle - completed Intermediate prognosis 4 VIP vs 4 BEP no difference in cure rates but increased toxicity with VIP de Wit BJC 1998 78(6) 828-826
Current but temporarily suspended trial run by EORTC is testing the addition of a another relatively new drug with has shown activity refractory disease
The NCRN Testis Clinical Study Group are also looking at dose intensity again by trying to short the cycle length to 2 weekly by using pegylated GCSF to accelerate the recovery of white cell count in between each cycle

Increase dose intensity by intensive induction/sequencing?
Increase dose of cisplatin?
Myeloablative chemotherapy with stem cell support
These represent a challenging group of patient requiring multi-disciplinary team working.
It is an area where answers are need and when ever possible patients should be entered into clinical trials
Appropriate surgical management of residual retroperitoneal and other sites of disease is required.
Evidence for improved outcomes for poor prognosis patient over the years through involvement of clinical trial protocols and also there is a volume effect in outcomes are worse in situations entering < 5 patients per clinical trial protocol. Collette, L J Natl Cancer Inst, 1999. 91(10): p. 839-46.

NCRN Accelerated BEP with 2 weekly cycle - completed The NCRN Testis Clinical Study Group have completed a randomised phase II of C-BOP-BEP with BEP over half the patients have been recruited but accrual to the study is slower than expected.
CBOP-BEP consists of 6 weeks of induction therapy including cisplatin, carboplatin , vincristine and etoposide and a modified BEP with 15 IU Bleomycin per week though the entire 16 weeks
CBOP-BEP it has yielded impressive 5 year survival rate in this tricky group of patients in both single institution and multi- centre phase II trials
Accelerated BEP study is also suitable for the poor prognosis group. But I personally have concerns for those with bulky disease with this approach

Chevreau increased toxicity, no improvement in survival
Bottom line is in these poor prognosis patients as yet no method of dose intensification such as high dose chemotherapy or the use of growth factors nor the introduction of new drugs to date has increased survival end-points over BEP x 4 alone.
The literature regarding high dose chemotherapy is extremely complex due to the heterogeneity of patients entering the studies
HD is used as front line treatment for poor prognosis disease, and consolidation treatment, salvage treatment on first and subsequent relapse and for refractory disease.
Motzer study JCO 2007 25 247-256 BEP vs BEP plus HD no difference in survival outcomes, but sub-group analysis if Markers failed to normalise with an acceptable T1/2 those with HD did better than standard therapy.

Studies now looking at sequential c.f. single HD procedures seem to better tolerated Lorch, A JCO 2007. 25(19): p. 2778-84.
As yet no RCT have shown a definite benefit but what seems important is establishing prognostic markers for survival after HD.

51. RESECTION OF RESIDUAL MASSES
52. RESECTION OF RESIDUAL MASSES
applies to all significant lesions in pts. treated for metastatic teratoma
30-40% will have mature teratoma
30-40% will have necrosis
10-20% will have viable cancer
complete excision is the aim in all cases
majority of pts. are cured; those at highest risk of relapse have >10% viable cancer in resected lesions, initial intermediate or poor IGCCCG group and incomplete excision
Predictive model for PFS and OS (Fizazi, K JCO; 2001 19:2647-57)
30% discordant histology between RPLND and lung lesions, but high concordance with bilateral lung lesions
53. RESECTION OF RESIDUAL MASSES Standard approach for most (all > 2 cm) teratoma residual masses; individualised approach for seminoma patients
Open issues:
RPLND as primary therapy for high risk stage 1 and stage II?
Reduction of surgical morbidity?
Who needs chemotherapy post surgery?
What is optimal post-operative chemotherapy ?
Avoid surgery in selected patients? (e.g. by use of PET scanning) Recent paper Oldenburg JCO 2003 33% residual masses <2cm have tumour tissue (differentiated teratoma or viable cancer)
Chemo therapy is not indicated for good and probably intermediate risk group defined by clear resection margin< 10 % viable cells and initial IGCCC good prognosis group Fizazi, K Ann Oncol, 2008. 19(2): p. 259-64.

(JC0 2008 26:5930-35)
56. RELAPSED DISEASE Overall 10-20% of advanced disease patients do require treatment for relapse/recurrence
10 - 50% of these are still curable
Platinum resistance is associated with poor outcome and few long term survivors
management often requires repeat surgery with/without further chemotherapy
late relapses can be most difficult
Specialist centre referral is essential
No adequately powered randomised trials of second-line/salvage therapies have been performed
Salvage drugs standard newer cytotoxics oxaliplatin, gemcitabine - biological drugs have not seen much promise yet unlike in common tumour types and certain other rare cancers
Around 90 germ cell patients have been treated with biological agents to date some minor tomour marker responses are seen
Investigation of PARP inhibitors may well be indicated on the basis of cell lie activity
Despite the expression of c-Kit in seminomas little significant clinical activity is seen
There are 1-2 case reports of bevacuzimab in refractory germ cell cancerSalvage drugs standard newer cytotoxics oxaliplatin, gemcitabine - biological drugs have not seen much promise yet unlike in common tumour types and certain other rare cancers

59. RELAPSED DISEASE Phase II of TIP (taxol, ifosfamide, cisplatin) in first relapse at MSKCC (Kondagunta G, JCO 2005; 6549-55)
Long term progression free rate 78%
MRC TIP less dose intense & results less impressive (Mead , G et al. BJC 2005; 93:178-184)
Phase II of GEM TIP in the near future
High dose as initial salvage - single randomised trial (n=280) (Pico JL; Ann Oncol 200516: 1152-9,)
4 VeIP vs 3 VeIP + 1 CEC + PBSCT
No differences in survival; higher death rate for HDC
Phase II date suggesting event free survival rates 23 - 40%
Matched pair analysis suggests 10 % improved EFS and OS
Benefit of drugs over platinum and etoposide is controversial
Multi-cycle HD seems better tolerated
Largest retrospective series (n=184) from Indiana event free survival = 63% (Einhorn, L NEJM 2007;3577:340-348)
60. RANDOMIZED PHASE III TRIAL OF INITIAL SALVAGE CHEMOTHERAPY FOR PATIENTS WITH GERM CELL TUMORS (TIGER) Increasingly high dose is seen as the only potential cure for those patients with poor risk factors @ relapse
These are relatively rare in number and an international collaborative approach across a variety of germ cell research groups to try to answer this question

3 situations
- brain met at presentation do reasonably well 45 % 5 year survival
- Isolated brain met as sanctuary site 39% 5 year survival
- Brain mets as part of systemic progression 2 % 5 year survival
Extra-gonadal primaries sites- approach same generally though primary medisatinal NSGCT tend to do very badly compared to other sites and automatically fall in to IGCCCG poor group Brain metastases consideration for multi-modality treatment but remember Lance Armstrong

1-6 % of cases
Commonest site RPLN
Often marker negative, if present usually AFP
Histology glandular patter and yolk sac

66. Mortality Statistics We know from cohort studies, case series from single institutions and from large single regional, national and multinational combined cancer registries, that testicular cancer patients have increased mortality compared to the normal population. The causes are of death included second malignancies and non-malignant causes such as cardiovascular and GI disease.
A variety of second cancer and other disease have documented increased incidence in testicular cancer patients.
Also some of the risk factors for these conditions are seen with increased frequency or clustering in our patients.
Generally the data in these studies is generated by comparing the mortality or incidence in the cancer survivor to that of usually aged matched local populations, to generate standardised mortality or incidence rates respectively.
Fossa 2004
There did not appear to be decrease in the elevated SMR in the latter of the 3 chronological periods study 1990-1997 for second cancers, which is a concern as it may have been anticipated that by this point that reductions in the size of radiotherapy fields and standard platinum based therapy may have reduced the second malignancy rate associated with older treatments.
Robinson et al
In a similar study in SE England and looked at the SMR according to the period of diagnosis, histological type. Since 1960s for all period since diagnosis the SMRs have decreased but now largest excess mortality seen in the early years from diagnosis.
Fossa 2007
This large multinational registry study looked at the SMR for non-cancer deaths in survivors of testicular cancer. The overall SMR was increased with a 6 % increase in mortality compared to the general population. SMRs were statistically significantly increased for infections, digestive disease and for men diagnosed < 35 years of age the SMR for circulatory disease was 1.23 (95% CI 1.09-1.39). Generally the SMRs for NSCGT were higher than for seminoma patients, 3.07 vs 1.82
Zagars[5]
In this more restrictive, yet relatively large, study of stage I and II seminomas treated with surgery and XRT at a single institution with radiotherapy alone the SMR rate was not significantly raised in the first 15 years of FU. Overall and beyond 15 years of follow up the SMR for second cancers and cardiac disease were also significantly elevated. The increased mortality appeared in patients who did and not received mediastinal XRT, thought the latter group were the only one to demonstrate this before 15 years of follow up. A striking feature in this Texan paper was the median age of death for cardiac cause was 62 and for cancer was 59, these are bad even for the West of Scotland !

67. Incidence Statistics Robinson et al showed increased incidence rates for a variety of cancers which were seen with different increased frequencies with the time elapsed since diagnosis including for:
For seminomas, there was a significant excess of cancers of the colon, soft tissue and bladder in the long term, of pancreatic cancer in both the medium and long term
For NSGCT, significant excesses were found in the long term for cancers of the stomach, rectum and pancreas
Richardi study showed there was no reduction in the elevated SIR with era of treatment and generally all SIR increased with increasing length of follow up.
Latent
One of the more recent publications regarding late effects is a comprehensive study from Holland published in 2007 in JCO 25: 4370-4378, it is called the LATENT Latent Adverse Treatment Effects in Netherlands Testicular cancer survivors
2, 707 5-year survivors identified from Dutch cancer registries divided into 3 group. chemo, infra-diaphragmatic XRT and surgery alone, patients were treated between 1965- 1995
There is comparison of the incidence of second malignancies and cardiovascular disease according to age, sex, and calendar specific rates of the general population.
After median FU of 17.6 years of 90 % Dutch testis cancer patients. 270 had developed second malignancy and 357 developed CV disease MI, angina, CCF.
By 20 years cumulative incidence 4 % case second neoplasm and CV disease in chemo treated group and 1.5% in XRT group compared to surgery, this equates to a 1.8 fold increase in either major toxicity for those treated with infra-diaphragmatic XRT and 1.9 for chemotherapy compared to surgery alone.
For comparison smoking increases the risk of either second major complication by 1.7 fold
Infra-diaphragmatic XRT < 35Gy did not increase the CV risk compared to surgery alone, but was associated with 2.6 fold risk of second cancer.
Chemotherapy increased the risk of second cancer by 2.1 and increased risk of CV by 1.7 disease compared to surgically treated patients.
For patients treated with both modalities cumulative incidence of second cancer or cardio-vascular was 26.7 %.

68. Increased Cardio-vascular disease Meinardi
This Dutch was a case control single centre study of stage one patients managed by surgery alone with those receiving chemotherapy with at least 10 years of follow-up. PVB was the commonest regime used. The latency between treatment and cardiac event was 9-16 years. All cases with had an event had at least on cardiac risk factor and 97% of chemotherapy treated patients had at least one factor. Those risk factors with significant difference frequency compared to stage I patients are shown in the table. There was no difference in smoking history, FH of CV disease between these two groups. 33 % of the chemotherapy patients had diastolic dysfunction on echocardiogram which is a predictor early myocardial dysfunction.
In a large Dutch study [18] where cardiac events were defined as MI, CCF. The SIR for MI was significantly increased for NSGCT survivors aged of less than 45 (SIR = 2.06) and 45 to 54 years (SIR = 1.86) but significantly decreased for survivors > 55 years.
Median time to MI was 14 years
Cisplatin, vinblastine, and bleomycin (PVB) chemotherapy (CT) was associated with a 1.9-fold (95% CI, 1.7- to 2.0-fold) increased MI risk
BEP was associated with a 1.5-fold (95% CI, 1.0- to 2.2-fold) increased CVD risk and was not associated with increased MI risk (hazard ratio = 1.2; 95% CI, 0.7 to 2.1)., but the median follow up in this sub set was shorter than the median time to MI.
Smoking was associated with a 2.6-fold (95% CI, 1.8- to 3.9-fold) increased MI risk.
The authors conclude that NSCGT survivors have slight increased MI risk at young age. Physicians should be aware of excess CVD risk associated with mediastinal radiotherapy, PVB CT, and recent smoking. Intervention in modifiable cardiovascular risk factors is important in survivors of testis cancer.

69. Leukaemia incidence This slide summaries some of the increased rates of leukaemia seen in germ cell patients, generally the SIR is 2-7 fold that of the various control populations.
Of concern in the study by Richardi the SIR increased to 37.9 (95% CI: 18.9-67.8) among NSCGT patients diagnosed since 1990
Howard
These the SIRs are highest in the first 5 years post treatment, but remain elevated at over 15 years.
By 30 years the cumulative rate of leukaemia was 0.23%. There was no statistically significant difference in the excess absolute or relative risk for those treated initially with chemotherapy and radiotherapy.
Travis {Travis, 2000 #288} study was registry based with those developing leukaemia were aged matched for controls within the registry. A variety of different alkylating agents and XRT schedules were seen I have concentrated on the data for more modern germ cell cancer strategies. The median latency was 5 years and they estimated that for 10 000 men treated and followed for 15 years with;
standard dose of radiotherapy (25Gy) to abdomen may lead to an excess of 9 leukaemia cases
Cisplatin dose 650 mg may lead to 16 excess leukaemia cases
So although the excess relative risks are high the excess absolute risk is small, the benefits if treatment still out weigh this risk.

70. Androgens
Encourage healthy lifestyle
Awareness of increased risk of cardiovascular disease
Psychological usually not a problem and not related to treatment modality
(Mykletun, A JCO, 2005. 23(13): p. 3061-8) LATE EFFECTS Testicular cancer through Lance Armstrongs Livestrong Foundation has led the way with survivorship issues not been applied to other cancers.
Up to 20% will have low androgens even at Dx, this is asscoaited with worse QOL, sexual function and adverse health outcomes androgen supplementation is to be studies in the TRYMS study (? ACRONYM) with QOL and fat mass indices as end points
It is important to spot and support those who dont seem to be coping well and thus the MDT approach we have with the TYA CNS as we dont have a germ cell specific CNS.
Mykletun, A JCO, 2005. 23(13): p. 3061-8. QOL in 1400 survivors of testicular cancer showed no significant difference compared to matched controls and wasnt dependent on treatment modality however those experiencing test cancer related stress and reported more side effect were likely to have reduced QOL scores.
In follow up we looked at our lack of communication of normal results and somewhat surprisingly most are well adjusted and dont feel the need for individual communication of normal results.

71. CONCLUSIONS Maximise survival rates whilst minimising toxicities if at all possible
BEP remains standard primary treatment option for all patients with metastatic GCT although schedule/cycles may differ according to risk
Alternatives to BEP need to be evaluated in clinical trials
Still need better treatments for poor risk patients and relapsed disease
