ABSTRACTObjective In the Middle East, there is a paucity of data regarding germ cell tumor characteristics and treatment outcomes. Herein, we aim to present the largest series in Jordan reporting our cancer center experience managing GCT.Methods: Between 2010 and 2020, a total of 241 patients with a pathological diagnosis of GCT were treated at our cancer center. Demographic, epidemiologic, and pathological data were retrospectively collected. In addition, survival and relapse outcomes based on tumor stage and adjuvant treatment were collected.Results A total of 241 patients were diagnosed with GCT, of whom 108 (44.8%) had seminoma and 133 (55.2%) had non-seminoma tumors (NSGCT). Median age (interquartile range) at diagnosis was 31 years (25–36). Patients with seminoma (68.5%) had pT1 disease post orchiectomy, while only 37.5% of patients with NSGCT had pT1 on final pathology. Elevated tumor markers such as beta-human chorionic gonadotropin were present in 10% of seminomas. Following radical orchiectomy and staging, 88 (36.5%) went for active surveillance while 153 patients (63.5%) received adjuvant treatment. With regard to pathology slides read outside, rereading by our genitourinary pathologist yielded a discrepancy on GCT type in 41 (19.3%) out of 212 patients. The median follow-up was 36 (24–48) months. Twenty-two patients relapsed after an average follow-up time of 39 months. The 5-year overall survival for stage I, II, and III was 98%, 94%, and 87%, respectively, and 3-year recurrence-free survival for stage I, II, and III was 94.8%, 78%, and 67%, respectively.Conclusion Our data on testicular GCT including demographic, histological, and treatment outcomes were comparable to that of developed countries. In light of the pathology discrepancy rate revealed in our study, authors recommend a second review by expert genitourinary pathologists to ensure proper classification and management of GCT.
