Background and Objective: Few longitudinal studies have described the prevalence and development of biochemical hypogonadism in aging testicular cancer survivors (TCSs) in comparison to men from the general population (control subjects)., Methods: Serum total and free testosterone (T total , T free ) were measured in 593 TCSs median11 and 27 years after TC diagnosis (Survey-First; Survey-Last). Post-treatment adverse health outcomes (AHOs) were recorded. The results were compared to those in 578 control subjects. Treatment was stratified as surgery alone, radiotherapy alone, or platinum-based chemotherapy. Biochemical hypogonadism was defined as T total <8 nmol/l, or as T total <12 nmol/l and T free <225 pmol/l. We used multivariable logistic regression analysis to explore associations with age and treatment intensity. Statistical significance was set at p  <0.05., Key Findings and Limitations: Between the first and last survey the prevalence of biochemical hypogonadism increased from 12% to 41% in the TSC group and from 5% to 11% in the control group. Three decades after diagnosis, the probability of biochemical hypogonadism was significantly correlated with increasing age and greater treatment intensity. The combined age- and treatment- related probability of hypogonadism was more than threefold higher in the TCS group than in the control group. At the last survey, fewer eugonadal than hypogonadal TCS men reported at least one AHO attributable to androgen deficiency (54% vs 72%; p  <0.001). Limitations include the availability of only one blood sample per survey wave., Conclusions and Clinical Implications: For aging TCSs, the probability of biochemical hypogonadism depends on age and prior treatment intensity and is threefold higher than for control subjects at 30 yr after diagnosis. As late hypogonadism is associated with AHO incidence, the development of hypogonadism should be monitored via regular blood tests during TCS follow-up., Patient Summary: Depending on the treatment they received, older survivors of testicular cancer (TC) are at persistent risk of lower testosterone levels. Our study revealed low testosterone in 40% of TC survivors older than 60 years compared to 10% of similarly aged men from the general population. Low testosterone is associated with chronic conditions such as diabetes, fatigue, and/or erectile dysfunction. Testosterone should be regularly monitored during follow-up for TC survivors., (© 2025 The Authors.)

Aims: To resolve the ongoing controversy surrounding the impact of teratoma (TER) in the primary among patients with metastatic testicular non-seminomatous germ-cell tumours (NSGCT)., Patients and Methods: Using the International Germ Cell Cancer Collaborative Group (IGCCCG) Update Consortium database, we compared the survival probabilities of patients with metastatic testicular GCT with TER (TER) or without TER (NTER) in their primaries corrected for known prognostic factors. Progression-free survival (5y-PFS) and overall survival at 5 years (5y-OS) were estimated by the Kaplan-Meier method., Results: Among 6792 patients with metastatic testicular NSGCT, 3224 (47%) had TER in their primary, and 3568 (53%) did not. In the IGCCCG good prognosis group, the 5y-PFS was 87.8% in TER versus 92.0% in NTER patients (p = 0.0001), the respective 5y-OS were 94.5% versus 96.5% (p = 0.0032). The corresponding figures in the intermediate prognosis group were 5y-PFS 76.9% versus 81.6% (p = 0.0432) in TER and NTER and 5y-OS 90.4% versus 90.9% (p = 0.8514), respectively. In the poor prognosis group, there was no difference, neither in 5y-PFS [54.3% in TER patients versus 55.4% (p = 0.7472) in NTER], nor in 5y-OS [69.4% versus 67.7% (p = 0.3841)]. NSGCT patients with TER had more residual masses (65.3% versus 51.7%, p < 0.0001), and therefore received post-chemotherapy surgery more frequently than NTER patients (46.8% versus 32.0%, p < 0.0001)., Conclusion: Teratoma in the primary tumour of patients with metastatic NSGCT negatively impacts on survival in the good and intermediate, but not in the poor IGCCCG prognostic groups., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Silke Gillessen: Personal honoraria: advisory boards from Amgen, MSD; invited speaker ESMO, Swiss group for Clinical Cancer Research (SAKK), German-speaking European School of Oncology (DESO), Swiss Academy of Multidisciplinary oncology (SAMO); travel grant from AstraZeneca, Bayer.

Purpose: The classification of the International Germ-Cell Cancer Collaborative Group (IGCCCG) has been a major advance in the management of germ-cell tumors, but relies on data of only 660 patients with seminoma treated between 1975 and 1990. We re-evaluated this classification in a database from a large international consortium., Materials and Methods: Data on 2,451 men with metastatic seminoma treated with cisplatin- and etoposide-based first-line chemotherapy between 1990 and 2013 were collected from 30 institutions or collaborative groups in Australia, Europe, and North America. Clinical trial and registry data were included. Primary end points were progression-free survival (PFS) and overall survival (OS) calculated from day 1 of treatment. Variables at initial presentation were evaluated for their prognostic impact. Results were validated in an independent validation set of 764 additional patients., Results: Compared with the initial IGCCCG classification, in our modern series, 5-year PFS improved from 82% to 89% (95% CI, 87 to 90) and 5-year OS from 86% to 95% (95% CI, 94 to 96) in good prognosis, and from 67% to 79% (95% CI, 70 to 85) and 72% to 88% (95% CI, 80 to 93) in intermediate prognosis patients. Lactate dehydrogenase (LDH) proved to be an additional adverse prognostic factor. Good prognosis patients with LDH above 2.5× upper limit of normal had a 3-year PFS of 80% (95% CI, 75 to 84) and a 3-year OS of 92% (95% CI, 88 to 95) versus 92% (95% CI, 90 to 94) and 97% (95% CI, 96 to 98) in the group with lower LDH., Conclusion: PFS and OS in metastatic seminoma significantly improved in our modern series compared with the original data. The original IGCCCG classification retains its relevance, but can be further refined by adding LDH at a cutoff of 2.5× upper limit of normal as an additional adverse prognostic factor., Competing Interests: Jörg BeyerHonoraria: Roche, Janssen Oncology, AstraZeneca, Astellas Pharma, Bayer, Ipsen Gedske DaugaardConsulting or Advisory Role: Sanofi/Aventis, Astellas Pharma, Bayer, MSD Oncology, Bristol-Myers Squibb/PfizerTravel, Accommodations, Expenses: Astellas Pharma Darren R.

Purpose: The classification of the International Germ Cell Cancer Collaborative Group (IGCCCG) plays a pivotal role in the management of metastatic germ cell tumors but relies on data of patients treated between 1975 and 1990., Materials and Methods: Data on 9,728 men with metastatic nonseminomatous germ cell tumors treated with cisplatin- and etoposide-based first-line chemotherapy between 1990 and 2013 were collected from 30 institutions or collaborative groups in Europe, North America, and Australia. Clinical trial and registry data were included. Primary end points were progression-free survival (PFS) and overall survival (OS). The survival estimates were updated for the current era. Additionally, a novel prognostic model for PFS was developed in 3,543 patients with complete information on potentially relevant variables. The results were validated in an independent data set., Results: Compared with the original IGCCCG publication, 5-year PFS remained similar in patients with good prognosis with 89% (87%-91%) versus 90% (95% CI, 89 to 91), but the 5-year OS increased from 92% (90%-94%) to 96% (95%-96%). In patients with intermediate prognosis, PFS remained similar with 75% (71%-79%) versus 78% (76%-80%) and the OS increased from 80% (76%-84%) to 89% (88%-91%). In patients with poor prognosis, the PFS increased from 41% (95% CI, 35 to 47) to 54% (95% CI, 52 to 56) and the OS from 48% (95% CI, 42 to 54) to 67% (95% CI, 65 to 69). A more granular prognostic model was developed and independently validated. This model identified a new cutoff of lactate dehydrogenase at a 2.5 upper limit of normal and increasing age and presence of lung metastases as additional adverse prognostic factors. An online calculator is provided (https://www.eortc.org/IGCCCG-Update)., Conclusion: The IGCCCG Update model improves individual prognostication in metastatic nonseminomatous germ cell tumors. Increasing age and lung metastases add granularity to the original IGCCCG classification as adverse prognostic factors., Competing Interests: Silke GillessenConsulting or Advisory Role: Astellas Pharma, Janssen, Bayer, Orion Pharma GmbH, Tolero Pharmaceuticals, MSD Oncology, Roche, Amgen, PfizerSpeakers' Bureau: Janssen-CilagPatents, Royalties, Other Intellectual Property: Method for biomarker (WO 3752009138392 A1)Travel, Accommodations, Expenses: ProteoMedixOther Relationship: ProteoMediX, Aranda Pharma Gedske DaugaardConsulting or Advisory Role: Sanofi/Aventis, Astellas Pharma, Bayer, MSD Oncology, Bristol-Myers Squibb/PfizerTravel, Accommodations, Expenses: Astellas Pharma Ronald De WitHonoraria: Sanofi, Merck Sharp and DohmeConsulting or Advisory Role: Sanofi, Merck Sharp and Dohme, Janssen, Bayer, Astellas PharmaResearch Funding: Sanofi, BayerTravel, Accommodations, Expenses: Bayer Costantine AlbanyStock and Other Ownership Interests: AdvaxisHonoraria: Sanofi, AstraZeneca, Seattle GeneticsConsulting or Advisory Role: Seattle Genetics, AstraZeneca/MedImmuneSpeakers' Bureau: SanofiResearch Funding: Astex Pharmaceuticals, Merck, Bristol-Myers Squibb, Lilly, BayerTravel, Accommodations, Expenses: Sanofi Alexey TryakinConsulting or Advisory Role: BioCad, Roche/Genentech, Bristol-Myers Squibb, Eisai, Merck Sharp and DohmeSpeakers' Bureau: Bayer Health, BioCad, Lilly, Merck Serono, Sanofi, Amgen, Bristol-Myers Squibb, Eisai, Merck Sharp and DohmeTravel, Accommodations, Expenses: Novartis, BioCad, Bayer, Veropharm, Sanofi Karim FizaziHonoraria: Janssen, Sanofi, Astellas Pharma, BayerConsulting or Advisory Role: Janssen Oncology, Bayer, Astellas Pharma, Sanofi, Orion Pharma GmbH, Curevac, AstraZeneca, ESSA, Amgen, Bristol-Myers Squibb, Clovis OncologyTravel, Accommodations, Expenses: Janssen, MSD Olof StahlHonoraria: Bayer Ugo De GiorgiConsulting or Advisory Role: Pfizer, Janssen, Astellas Pharma, Sanofi, Bristol-Myers Squibb, Bayer, Ipsen, Merck, MSD, PharmaMar, NovartisResearch Funding: Sanofi, AstraZeneca, RocheTravel, Accommodations, Expenses: Bristol-Myers Squibb, Ipsen, Janssen, Pfizer, Roche Aaron HansenConsulting or Advisory Role: Merck, GlaxoSmithKline, Bristol-Myers Squibb, EisaiResearch Funding: Karyopharm Therapeutics, Merck, Bristol-Myers Squibb, Boehringer Ingelheim, GlaxoSmithKline, Roche/Genentech, Janssen, AstraZeneca/MedImmune, Astellas Pharma, Macrogenics Robert HuddartEmployment: Aspen Parkside HopsitalLeadership: Cancer Clinic London Limited liability partnershipHonoraria: Janssen OncologyConsulting or Advisory Role: Bristol-Myers Squibb, Roche, Merck Sharp and Dohme, Janssen Oncology, Nektar, BayerSpeakers' Bureau: Roche, MSD, RocheResearch Funding: Merck Sharp and Dohme, Roche, Bristol-Myers Squibb, JanssenPatents, Royalties, Other Intellectual Property: Royalties for drug discovery from JanssenTravel, Accommodations, Expenses: Janssen Oncology, Roche/Genentech, MSD Oncology, Nektar Andrea NecchiEmployment: BayerStock and Other Ownership Interests: BayerHonoraria: Roche, Merck, AstraZeneca, Janssen, Foundation Medicine, Bristol-Myers SquibbConsulting or Advisory Role: Merck Sharp and Dohme, Roche, Bayer, AstraZeneca, Clovis Oncology, Janssen, Incyte, Seattle Genetics/Astellas, Bristol-Myers Squibb, Rainier Therapeutics, GlaxoSmithKline, FerringResearch Funding: Merck Sharp and Dohme, AstraZeneca, IpsenTravel, Accommodations, Expenses: Roche, Merck Sharp and Dohme, AstraZeneca, Janssen, Rainier TherapeuticsOther Relationship: Bayer Christopher SweeneyStock and Other Ownership Interests: LeuchemixConsulting or Advisory Role: Sanofi, Janssen Biotech, Astellas Pharma, Bayer, Genentech/Roche, AstraZeneca, Pfizer, Amgen, Celgene, LillyResearch Funding: Janssen Biotech, Astellas Pharma, Sanofi, Bayer, Dendreon, PfizerPatents, Royalties, Other Intellectual Property: Leuchemix, Parthenolide, Dimethylaminoparthenolide.
