[Pathological Complete Response of Metastatic Testicular Tumor with Persistent Low Level Positive Human Chorionic Gonadotropin after Chemotherapy].
We describe a case of testicular tumor with multiple metastasis to the lung,retoroperitoneal lymph node, and brain. After chemotherapy the retroperitoneal lymph node and brain metastasis disappeared,but the multiple pulmonary metastases but not disappear,although they were reduced in size. Since the human chorionic gonadotoropin (HCG) was persistently dected at a low level,we performed a testosterone tolerance test. The HCG level became undetectable for a while,but was detected at a low level again. Then the patient underwent residual tumor removal of some of the residual pulmonary disease,which was diagnosed as tumor necrosis. The patient has been followed on an ambulatory basis after surgery for 12 months without recurrence. In this case a definitive diagnosis was difficult,because of the low positive level of HCG.
