[Metastatic liver tumor arising from prostate cancer following transurethral resection of the prostate--a report of two cases].
We herein present a report of metastatic liver tumor arising from prostate cancer following transurethral resection of the prostate (TUR) in two patients. The two patients were diagnosed as having moderately differentiated prostate adenocarcinoma, either stage C or B2, and underwent hormonal and/or radiation therapy. TUR was performed due to the patients' complaints of urinary outlet obstruction. Liver metastasis, without evidence of bone or pulmonary metastasis, was then noted 23 and 5 months later in the patients with stage C and B2 prostate cancer, respectively. It is possible that the process of TUR is related to the release of tumor cells from the prostate into the systemic circulation and involved in the development of liver metastasis.
