“…In 29 series in which the number of ovarian carcinoma patients is available, 34,728 ovarian carcinoma patients were surveyed, and 413 (1.19%) of them were found to have CNS metastases [6, 20–22, 24–27, 29–31, 33–35, 37, 39–43, 45–49, 52–55] (Table 1). The incidence of CNS metastasis among ovarian carcinoma patients was <1% in 5 series [20, 21, 24, 47, 48], 1–1.9% in 10 series [22, 27, 33, 39, 41–43, 49, 54, 55], 2–2.9% in 8 series [6, 29, 31, 34, 35, 45, 46, 53], 3–3.9% in 3 series [37, 40, 52], and ≥4% in 3 series [25, 26, 30] (Table 1). The claim made by some authors that the incidence of brain metastases among ovarian carcinoma patients is rising rapidly and approaching 12% [30] is not supported by most series published in the literature showing that the incidence of brain metastasis among ovarian carcinoma patients is within the range of 1–3% (Table 1).…”
