The classification of the International Germ-Cell Cancer Collaborative Group (IGCCCG) has been a major advance in management germ-cell tumors, but relies on data only 660 patients with seminoma treated between 1975 and 1990. We re-evaluated this database from large international consortium.Data 2,451 men metastatic cisplatin- etoposide-based first-line chemotherapy 1990 2013 were collected 30 institutions or collaborative groups Australia, Europe, North America.

To offer minimized risk-adapted adjuvant treatment on a nationwide basis for patients with clinical stage 1 (CS1) nonseminomatous germ-cell testicular cancer (NSGCT). The aim was to reduce the risk of relapse and thereby reducing need later salvage chemotherapy while maintaining high cure rate.From 1998 2005, 745 Norwegian Swedish were included into prospective, community-based multicenter Testicular Cancer Project (SWENOTECA) management program. Treatment strategy depended presence or...

Purpose A binational, population-based treatment protocol was established to prospectively treat and follow patients with seminomatous testicular cancer. The aim standardize care for all seminoma further improve the good results expected this disease. Patients Methods From 2000 2006, a total of 1,384 Norwegian Swedish were included in study. Treatment clinical stage 1 (CS1) surveillance, adjuvant radiotherapy, or carboplatin. In metastatic disease, recommended radiotherapy CS2A...

From 1995 to 2003, 603 adult patients from Sweden and Norway with metastatic testicular nonseminomatous germ cell tumor (NSGCT) were included prospectively in a population-based protocol strict guidelines for staging, treatment, follow-up. Patients extragonadal primary or previous treatment contralateral excluded. The basic strategy was individualize according initial marker response.Initial all two courses of standard bleomycin, etoposide, cisplatin (BEP), markers analyzed weekly. Good...

Long-term relative survival (RS) data for testicular germ cell tumor (TGCT) patients are scarce. We aimed to analyze long-term RS among TGCT diagnosed in Norway, between 1953 and 2012.Data sources were the Cancer Registry of Norway Norwegian Cause Death Registry. during 2012 classified by time diagnosis, histology, age, disease extent at diagnosis. Estimates obtained, a test comparing overall was performed. Corresponding obtained men with localized malignant melanoma before age 50.A total...

Using complete information on total treatment burden, this population‐based study aimed to investigate second cancer (SC) risk in testicular survivors (TCS) treated the cisplatin era. The Cancer Registry of Norway identified 5,625 1‐year TCS diagnosed 1980–2009. Standardized incidence ratios (SIRs) were calculated evaluate and site‐specific SC compared general population. Cox regression analyses evaluated effect SC. After a median observation time 16.6 years, 572 developed 651 nongerm cell...
