Outcomes in hormone-refractory prostate cancer are very poor. The time from progression to death is only 12-19 months. We present the case of a 69-year-old man with hormone-refractory prostate cancer and bone metastases treated with metronomic chemotherapy (cyclophosphamide based). He had had a colon adenocarcinoma ten years before. The atypical features of this case were an unusually long-lasting response to metronomic chemotherapy and an increase in serum levels of some non-prostate-specific tumor markers (CEA and CA 19-9) that was not related to a relapse of colon cancer. We hypothesize a potential role of hypoxia inducing CA 19-9 and CEA expression in tumor cells, which may predict the development of progressive resistance to antiangiogenic therapies.

Abstract

Outcomes in hormone-refractory prostate cancer are very poor. The time from progression to death is only 12-19 months. We present the case of a 69-year-old man with hormone-refractory prostate cancer and bone metastases treated with metronomic chemotherapy (cyclophosphamide based). He had had a colon adenocarcinoma ten years before. The atypical features of this case were an unusually long-lasting response to metronomic chemotherapy and an increase in serum levels of some non-prostate-specific tumor markers (CEA and CA 19-9) that was not related to a relapse of colon cancer. We hypothesize a potential role of hypoxia inducing CA 19-9 and CEA expression in tumor cells, which may predict the development of progressive resistance to antiangiogenic therapies.
