From "Bevacizumab combined with platinum–taxane chemotherapy as first-line treatment for advanced ovarian cancer: a prospective observational study of safety and efficacy in Japanese patients (JGOG3022 trial)":
In Japan, it is estimated that 9804 new patients develop ovarian cancer every year and the estimated annual number of deaths from this cancer is 4758, with its outcome being the worst among female genital tract cancers. The underlying reasons are that about 90% of ovarian cancer is epithelial carcinoma, with approximately 50% of epithelial ovarian cancers being Stage III or Stage IV advanced disease at diagnosis (2).
Is this a reduntand phrase, "epithelial carcinoma", or am I missing something? I thought that the word "carcinoma" meant "epithelial cancer".
