Impacto del tamaño tumoral y la invasión de la rete testis en la supervivencia libre de progresión de nuestros pacientes con seminoma testicular en estadio I. Estudio observacional retrospectivo en un hospital de referencia y revisión bibliográfica

Abstract

IntroductionThe aim of this study was to evaluate the impact of tumour size and rete testis invasion in progression free survival of our patients with stage I testicular seminoma. A literature review is also made. Material and methodsA retrospective observational study was performed. We included patients with stage I seminoma between January 2010 and July 2022. Patients without factors of poor prognostic –Group A– were compared with patients with factors of poor prognostic –Group B–. Kaplan-Meier curves and log-rank testing were used to compare progression free survival (PFS) between these groups. Statistical significance was considered at P ≤ .05. Results55 patients were included in this study. 20 patients (36.4%) were of good prognostic –Group A– and 35 (63.6%) had factors of poor prognostic –Group B–. The mean age was similar in both groups (mean ± standard deviation), 38.62 ± 9.04 years. The mean follow-up time was 63.5 ± 33.6 months. All the patients in group A and 25.7% of the patients in group B underwent active surveillance (AS). 26 patients (74.3%) of the patients in Group B were treated with one cycle of adyuvant carboplatin. Three patients suffered a relapse with retroperitoneal lymph nodes (10.3%), all of them were treated with three cycles of BEP, with a complete response of the disease. No statistical significant differences were found in PFS between Group A and B (log Rank P = .317). ConclusionsIndividualization of adjuvant treatment in stage I seminoma is important, avoiding the adverse effects derived from them.
