Abstract
We introduced a 61-year-old male with ductal adenocarcinoma of the prostate who underwent a tortuous diagnosis and treatment. Multi-disciplinary team meetings organized by our hospital have shown great value in the whole process. The patient presented with gross hematuria accompanied by frequent urination initially, and was diagnosed with ductal adenocarcinoma of the prostate involving right seminal vesicle gland and urethra by urethroscopy biopsy. The clinical stage of tumor was T3bN0M0. After 4 cycles of neoadjuvant chemotherapy, the tumor shrank significantly and the patient underwent a laparoscopic radical prostatectomy. But the patient declined to continue chemotherapy postoperatively. After 10 months, the serum prostatic specific antigen increased to 0.05 ng/mL, and multiple metastases were found in the patient's bilateral lungs. However, an unexpected diagnosis of seminal vesicle adenocarcinoma was put forward from another hospital after supplementary pathologic immunohistochemical examination. Then, after careful discussion and demonstration by our multi-disciplinary team experts, we insisted on the diagnosis of ductal adenocarcinoma of the prostate and suggested that the original regimen of chemotherapy should be continued. Up-to-date, 14 months after the operation, the patient continues to survive while undergoing ongoing active treatment as recommended.
