Abstract

Testicular seminoma is a relatively rare malignant tumor, with the most common site of recurrence and metastasis being the retroperitoneal lymph nodes. Since seminoma is highly sensitive to radiotherapy and chemotherapy, even if it metastasizes, its cure rate is still >95%. However, the long‑term toxicity and side effects of radiotherapy and chemotherapy cannot be ignored. Iodine‑125 seeds represent a low‑energy radioactive source that kills tumor cells while protecting the surrounding normal tissues, and brachytherapy using iodine‑125 seeds has been widely used for the treatment of various malignancies. In addition, carboplatin can be used as an alternative to cisplatin‑based combination chemotherapy to reduce the incidence of pulmonary toxicity, neurological damage and renal toxicity. In the present study, a case in which iodine‑125 seeds were implanted for the treatment of retroperitoneal metastatic seminoma is reported. The patient was diagnosed with postoperative recurrence of seminoma that metastasized to the retroperitoneal lymph nodes. Since the tumor was large and surrounded blood vessels, surgical intervention and external radiotherapy were not considered. Moreover, considering the potential long‑term toxic side effects of standard chemotherapy, a treatment plan for the patient using iodine‑125 seed implantation combined with carboplatin (AUC7) therapy was finally formulated. No disease recurrence or toxic reactions occurred during the 3‑year follow‑up after treatment. The present case therefore demonstrated the antitumor efficacy and reduced toxicity of iodine‑125 seeds combined with carboplatin for treating seminoma.
