KIT and ovarian carcinoma: Many reports have indicated high frequency (71–100%) of KIT expression in ovarian carcinomas (Arber et al, 1998; Parrott et al, 2000; Tonary et al, 2000), whereas others have shown lower levels of expression (0–22%) (Inoue et al, 1994; Schmandt et al, 2003; Singer et al, 2003).
