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.
forty two to 57% of patients with metastatic renal cell carcinoma (mrCC) receive the second-line therapy according to available data. in our analysis we wanted to determine the percentage of patients within intermediate/poor prognostic group mRCC who continued the treatment with the second line following progression on the first line and the percentage of patients who were not able to receive the second line treatment. Patients received sunitinib (first started on 12 August 2018) or pazopanib (first started on May 2014) at University Hospital Center Zagreb. The latest treatment started in December 2018. our results show that 39.4% of patients who received sunitinib and 37.9% of patients who received pazopanib, did not receive the second line treatment, which is consistent with available data. The question arises whether we could have helped those patients if we had access to newer therapeutic options.

Retrospektivnom analizom naših podataka htjeli smo prikazati postotak bolesnika s metastatskim karcinomom bubrega koji pripadaju srednjoj/lošoj prognostičkoj skupini a koji su nastavili liječenje drugom linijom nakon progresije na prvolinijsko liječenje. Također smo htjeli prikazati postotak bolesnika koji nisu bili u mogućnosti nastaviti drugolinijsko liječenje. Bolesnici su primali sunitinib (prvi bolesnik je započeo liječenje u svibnju 2014.) i pazopanib (prvi bolesnik je započeo liječenje 12. kolovoza 2018) u Kliničkom bolničkom centru Zagreb. Uključeni su bili bolesnici koji su liječenje započeli do kraja prosinca 2018. godine. 39.4% bolesnika koji su primali sunitinib i 37.9% bolesnika koji su primali pazopanib, nije primilo drugu liniju liječenja, što se podudara s literaturnim podacima. Nameće se pitanje, jesmo li navedenim bolesnicima mogli pomoći da smo imali dostupne novije terapijske opcije. KLJUČNE RIJEČI: metastatski karcinom bubrega, liječenje, sunitinib, pazopanib
