...Satoshi Washino; Masaru Hirai; Atsushi Matsuzaki; Yutaka Kobayashi Objective: To evaluate the usefulness of measuring serum CEA, CA19-9, and CYFRA 21-1 levels for the diagnosis and monitoring of bladder cancer. Materials and Methods: Serum levels of CEA, CA19-9, and CYFRA 21-1 were measured in 85...

.... Therefore, we examined immunohistochemically 11 hydronephrotic kidneys and 3 normal control kidneys using antibodies against CA19-9 and SPan-1 another sialylated carbohydrate antigen. Immunoreactivity for CA19-9 was seen in the transitional and tubular epithelia in most of the hydronephrotic kidneys (9...

...Takashi Tsuruta; Akimi Ogawa; Keiko Ishii; Shinsuke Ikado We determined whether a carbohydrate antigen in serum, CA19-9, serves as a marker for embryonal carcinoma. Serum CA19-9 was serially measured in 18 male patients with a germ cell tumor. Five of 8 patients with an embryonal carcinoma had...
