    (American Society of Clinical Oncology, 2020-04) Fischer, Stefanie; Tandstad, Torgrim; Cohn-Cedermark, Gabriella; Thibault, Constance; Vincenzi, Bruno; Klingbiel, Dirk; Albany, Costantine; Necchi, Andrea; Terbuch, Angelika; Lorch, Anja; Aparicio, Jorge; Heidenreich, Axel; Hentrich, Marcus; Wheater, Matthew; Langberg, Carl W.; Ståhl, Olof; Fankhauser, Christian Daniel; Hamid, Anis A.; Koutsoukos, Konstantinos; Shamash, Jonathan; White, Jeff; Bokemeyer, Carsten; Beyer, Jörg; Gillessen, Silke; Medicine, School of Medicine
    Purpose: Clinical stage I (CSI) nonseminoma (NS) is a disease limited to the testis without metastases. One treatment strategy after orchiectomy is adjuvant chemotherapy. Little is known about the outcome of patients who experience relapse after such treatment. Patients and methods: Data from 51 patients with CSI NS who experienced a relapse after adjuvant bleomycin, etoposide, and cisplatin (BEP) from 18 centers/11 countries were collected and retrospectively analyzed. Primary outcomes were overall and progression-free survivals calculated from day 1 of treatment at first relapse. Secondary outcomes were time to, stage at, and treatment of relapse and rate of subsequent relapses. Results: Median time to relapse was 13 months, with the earliest relapse 2 months after start of adjuvant treatment and the latest after 25 years. With a median follow-up of 96 months, the 5-year PFS was 67% (95% CI, 54% to 82%) and the 5-year OS was 81% (95% CI, 70% to 94%). Overall, 19 (37%) of 51 relapses occurred later than 2 years. Late relapses were associated with a significantly higher risk of death from NS (hazard ratio, 1.10 per year; P = .01). Treatment upon relapse was diverse: the majority of patients received a combination of chemotherapy and surgery. Twenty-nine percent of patients experienced a subsequent relapse. At last follow-up, 41 patients (80%) were alive and disease-free, eight (16%) had died of progressive disease, and one patient (2%) each had died from therapy-related or other causes. Conclusion: Outcomes of patients with relapse after adjuvant BEP seem better compared with patients who experience relapse after treatment of metastatic disease but worse compared with those who have de-novo metastatic disease. We found a substantial rate of late and subsequent relapses. There seem to be three patterns of relapse with different outcomes: pure teratoma, early viable NS relapse (< 2 years), and late viable NS relapse (> 2 years).

    (American Society of Clinical Oncology, 2021) Gillessen, Silke; Sauvé, Nicolas; Collette, Laurence; Daugaard, Gedske; de Wit, Ronald; Albany, Costantine; Tryakin, Alexey; Fizazi, Karim; Stahl, Olof; Gietema, Jourik A.; De Giorgi, Ugo; Cafferty, Fay H.; Hansen, Aaron R.; Tandstad, Torgrim; Huddart, Robert A.; Necchi, Andrea; Sweeney, Christopher J.; Garcia-Del-Muro, Xavier; Heng, Daniel Y. C.; Lorch, Anja; Chovanec, Michal; Winquist, Eric; Grimison, Peter; Feldman, Darren R.; Terbuch, Angelika; Hentrich, Marcus; Bokemeyer, Carsten; Negaard, Helene; Fankhauser, Christian; Shamash, Jonathan; Vaughn, David J.; Sternberg, Cora N.; Heidenreich, Axel; Beyer, Jörg; International Germ Cell Cancer Classification Update Consortium; Medicine, School of Medicine
    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.

    The prognostic impact of different tumor marker levels in nonseminomatous germ cell tumor patients with intermediate prognosis: A registry of the International Global Germ Cell Tumor Collaborative Group (G3)
    (Elsevier, 2019-11) Seidel, Christoph; Daugaard, Gedske; Tryakin, Alexey; Necchi, Andrea; Cohn-Cedermark, Gabriella; Ståhl, Olof; Hentrich, Marcus; Brito, Margarida; Albany, Costantine; Taza, Fadi; Gerl, Arthur; Oechsle, Karin; Oing, Christoph; Bokemeyer, Carsten; Medicine, School of Medicine
    Background Germ cell tumor patients with intermediate prognosis (IPGCT) according to the International Germ Cell Cancer Collaborative Group (IGCCCG) classification represent a heterogeneous group with different clinical features. This analysis was performed to investigate the prognostic impact of different tumor marker levels prior to first line chemotherapy within IPGCT. Methods For this study an international registry for IPGCT was established. Eligibility criteria were intermediate prognosis according to IGCCCG criteria, nonseminomatous histology, male sex, and age ≥ 16 years. Uni- and multivariate analysis were conducted to identify characteristics associated with survival outcomes. Receiver-Operating-Characteristic curve analysis was applied to find cut-off parameters. Five-year overall survival (OS) rate was the primary and 5-year progression-free survival rate the secondary endpoint. Results This database included 634 IPGCT with a median follow-up of 9.0 years (interquartile range: 14.35). Patients received first line treatment with platinum based chemotherapy, associated with a 5-year OS rate of 87%. The stratification of patients according to AFP levels revealed a correlation between AFP levels and outcome, associated with 5-year OS rates of 88% for AFP levels <1,000 IU/ml (n = 303), 89% for 1,000 to 2,000 IU/ml (n = 82), 87% for >2,000 to 6,000 IU/ml (n = 121), and 82% for >6,000 IU/ml (n = 57) prior first course of chemotherapy, respectively (P= 0.013). LDH levels prior fist course of chemotherapy also correlated with outcome associated with 5-year OS rates of 92% for <2 UNL (n = 271), 89% for ≥2 to 3 UNL (n = 85), 78% for >3 to 4 UNL (n = 34), and 77% for >4 UNL (n = 79), respectively (P= 0.03). Different HCG levels prior chemotherapy were not associated with outcome. In multivariable analysis AFP levels >6,000 IU/ml (P= 0.023; hazard ratio HR 2.263) or >1,982 IU/ml (P= 0.031; HR 1.722), and LDH levels >3 UNL (P< 0.001; HR 2.616) were independent prognosticators for OS. Conclusions Prognostication according to LDH and AFP levels prior chemotherapy could offer a new approach to stratify patients within the intermediate prognosis cohort. According to our findings, patients with AFP values above 6,000 IU/ml or/and LDH > 3 UNL represent an independent high risk cohort. Our results need to be confirmed in the upcoming IGCCCG reclassification.

    Survival and New Prognosticators in Metastatic Seminoma: Results From the IGCCCG-Update Consortium
    (American Society of Clinical Oncology, 2021) Beyer, Jörg; Collette, Laurence; Sauvé, Nicolas; Daugaard, Gedske; Feldman, Darren R.; Tandstad, Torgrim; Tryakin, Alexey; Stahl, Olof; Gonzalez-Billalabeitia, Enrique; De Giorgi, Ugo; Culine, Stéphane; de Wit, Ronald; Hansen, Aaron R.; Bebek, Marko; Terbuch, Angelika; Albany, Costantine; Hentrich, Marcus; Gietema, Jourik A.; Negaard, Helene; Huddart, Robert A.; Lorch, Anja; Cafferty, Fay H.; Heng, Daniel Y.

    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.
