# Robot-Assisted Laparoscopic Radical Prostatectomy for Prostatic Metastatic Recurrence from Testicular Cancer

## TL;DR

A young man with testicular cancer developed prostate metastasis and was successfully treated with chemotherapy and robot-assisted surgery.

## Contribution

This case highlights the use of robot-assisted prostatectomy for treating rare prostatic metastasis from testicular cancer.

## Key findings

- The patient showed tumor shrinkage after four cycles of chemotherapy.
- No recurrence was observed nine months after robot-assisted radical prostatectomy.
- Prostate metastasis should be considered in testicular cancer survivors with urinary symptoms.

## Abstract

Treatment evidence for malignancies metastatic to the prostate in young patients is scarce. Herein, we present a case of prostatic metastasis from testicular cancer treated with induction chemotherapy followed by robot-assisted radical prostatectomy. Case Presentation. The patient is a 34-year-old male who underwent radical orchiectomy for a left testicular tumor two years ago and was diagnosed with a mixed germ cell tumor. He was followed up without adjuvant therapy, but symptoms of dysuria lead to suspicion of a prostate tumor, which was diagnosed by prostate biopsy as seminoma of the prostate. After four cycles of chemotherapy, normalization of tumor markers, and tumor shrinkage on imaging, he underwent robot-assisted radical prostatectomy. No recurrence has been observed nine months after treatment.

In men with a history of testicular cancer presenting with lower urinary tract symptoms, it is important to consider recurrent prostate metastases.
