Can radiotherapy be a viable salvage treatment option for the relapsed seminoma confined to the infra-diaphragm region recurring after primary chemotherapy for bulky stage II seminoma?

摘要

There has been a paucity of research describing a potential role of radiotherapy as salvage treatment for recurrent seminoma following primary chemotherapy for bulky stage IIC seminoma. We report a case of a bulky stage IIC seminoma relapsed in the pelvis after primary chemotherapy and surgery for post-chemotherapy residual mass, which was subsequently salvaged with radiotherapy. The patient has remained free of relapse at 3.7 years post-salvage radiotherapy. This case demonstrates that radiotherapy can be a salvage therapeutic option for recurrent seminoma following primary chemotherapy for bulky stage IIC seminoma, provided that the recurrent tumour is confined to a limited area of the infradiaphragmatic region. There is a need for further study to examine the potential role of radiotherapy as a salvage therapeutic tool for post-chemotherapy recurrent seminoma.
