A Case of Bilateral Adrenal and Pleural Metastases from Prostate Cancer

Our case was 65 years old. At check-up, a high PSA level of 515 ng/ml was observed, the patient was diagnosed with having clinical stage D prostate cancer and a Maximum Androgen Blockade (MAB therapy) was started. In response to the exacerbated prostate cancer, we started a therapy involving the administration of 8 mg/kg body weight of dexamethasone and 55 mg/m2 of docetaxel every 3 weeks. After completing 8 courses, an enlargement of the bilateral adrenal tumor was observed, and after completing 12 courses, a pleural tumor was discovered and the PSA level was also increased. The patient was therefore diagnosed with having bilateral adrenal metastasis and pleural metastasis of prostate cancer through diagnostic imaging. So far, there have been no reports of multiple occurrences of prostate cancer in the adrenal glands and the pleura, thus making this case the first such case.
