title: Prognostic value of CD44 splice variant expression in ovarian cancer.
abstract: In 44 ovarian cancers, CD44 variant (CD44v) expression was investigated immunohistochemically using a variant-specific polyclonal antibody. Patients with CD44v-positive carcinomas had a significantly shorter disease-free survival than patients with CD44v-negative tumors. Overall survival was also significantly reduced for stages III and IV of the International Federation of Gynecology and Obstetrics. Furthermore, a highly significant inverse correlation was observed between CD44v expression and preoperative platelet count. Urinary neopterin concentration, a marker of cell-mediated immunostimulation, did not differ between CD44v-positive and -negative ovarian cancer patients. Moreover, in seven ovarian carcinoma cell lines, modulation of CD44v expression was analyzed by living cell radioimmunoassay. Interferon-alpha, interferon-gamma, tumor necrosis factor, transforming growth factor-beta, all-trans retinoic acid and cisplatin did not affect CD44v expression.
