A case of thrombopoietin-producing ovarian carcinoma confirmed by immunohistochemistry

A case of ovarian carcinoma with thrombopoietin production is reported. A 49-year-old Japanese woman had serous cystadenocarcinoma of the right ovary with peritoneal spread. The platelet count was elevated to 432 x 10(9)/L. Enzyme-linked immunosorbent assay of the serum demonstrated remarkably high levels of thrombopoietin (2.96 fmol/ml). Immunohistochemical examination using an antibody specific for thrombopoietin revealed positive staining in the carcinoma cells, confirming thrombopoietin production.

Synthesis and effects of novel thiazole derivatives against thrombocytopenia

5-(2-Pyridylsulfonyl)-2-thiazolamine (2) was effective both in mitomycin C (MMC)-induced thrombocytopenia and in an animal model of idiopathic thrombocytopenic purpura (ITP). It also suppressed the increase of autoantibodies against platelets in the ITP model and showed no blood toxicity. Chemical modification of 2 led to the discovery of more potent compounds against MMC-induced thrombocytopenia.
