Stage I seminoma: outcome of different treatment modalities & changes in patterns of care: A single institution experience.

Abstract

The mainstay for management of stage I seminoma is high inguinal orchiectomy with post-orchiectomy therapeutic options including active surveillance, chemotherapy or radiation therapy. To analyze different post-orchiectomy treatment modalities outcomes of stage I seminoma patients presented to NCI, Cairo University in the period from 2005-2019. A retrospective review of all patients' records with clinical stage I seminoma who presented to our institute in the period from 2005-2019 was done. Adjuvant treatment details were extracted and we compared overall survival (OS) and disease free survival (DFS) for different modalities and changes in patterns of care over this period. Thirty five patients were identified with thirty three patients eligible for analysis. Median age was 35 years (range, 19-52). Fourteen patients were kept under active surveillance, eleven patients received adjuvant carboplatin and eight patients received adjuvant radiation to para-aortic chain. Five-year OS was 100% for all patients regardless post-operative approach. Five-year DFS was 100% for patients who received adjuvant chemotherapy or radiotherapy versus 93% for patients who were kept under active surveillance (p=0.03). Clinical stage I seminoma is a favorable disease entity with favorable disease related outcomes regardless post-operative approach. Active surveillance is reasonable and safe given equal survival to active treatment.
