Abstract:
415 Background: Testicular germ cell tumors (t-GCTs) commonly present in age group 20-40 years (yrs). Older patients (pts) in many cancers have worse tolerance to therapy and outcomes. We examine herein the effect of older age in t-GCT pts. Methods: We conducted a chart-review-based retrospective analysis of pts of t-GCTs diagnosed and treated at our urogenital clinic from 2015-2021. Pts were divided into two groups: Age ≤40 years (Group A) and 〉 40 years (Group B). Multivariable Cox regression models were constructed to analyze the prognostic value of older age while adjusting for measured confounders. Results: A total of 298 patients of t-GCT were identified; the median age was 30 yrs (interquartile range 24-37), 43.0% with intermediate or poor risk, 64.8% patients with non-seminomatous GCT (NSGCT), 250 pts in gp A and 48 in gp B. Baseline characteristics in both gps differed significantly with respect to the risk category, and seminoma histology, while there was no difference for performance status (ECOG ≥2), see table. Bleomycin, cisplatin, and etoposide (BEP) was the most common chemotherapy (226/262 pts), and use of BEP was not different in 2 gps (p=0.249). Grade III/IV adverse effect burden was greater in gp B vs gp A for febrile neutropenia, nausea/vomiting, and diarrhea, while infertility was more in gp A (Table). Outcomes in terms of markers normalization (163 vs 33, p=0.408) and radiological response (complete remission, 93 vs 20, p=0.205) did not differ. Median overall survival was not reached in both gps, and the hazard ratio for age 〉 40 yrs was 1.91 (95% confidence interval 0.91-3.99, p =0.086), after adjusting for risk category, performance status, and response to therapy. Conclusions: Age does not deter the use of platinum-based therapy, which, although more toxic, has similar efficacy to younger pts of t-GCT. [Table: see text]
