OBJECTIVE Over the past 20 years, the incidence of endometrial cancer has increased remarkably in Japan. The number of elderly females has also increased within the population of Japan. We examined the impact of advanced age on the demographic and clinicopathological characteristics in Japanese patients with endometrial cancer. METHODS Data were collected(More)
OBJECTIVES Although the expression of estrogen receptor (ER) is usually found in uterine endometrioid adenocarcinomas, it has recently been reported to be found in some uterine serous carcinomas (USCs). This report describes the clinicopathologic features of USC with an expression of ER-α, with special reference to the prognostic significance of ER-α. (More)
The p53 signature (p53S) has been proposed to be a marker of the earliest phase of development of endometrial serous carcinoma. We examined the presence of p53S in the background endometrium in cases of endometrial carcinoma. From a series of 351 endometrial carcinomas, 225 (64.1 %) lesions, for which slides of the adjacent noncancerous endometrium were(More)
We herein examined the significance of the p53 expression in endometrial polyps (EMPs). A total of 133 EMPs, including 62 premenopausal and 71 postmenopausal women with EMP, were immunohistochemically studied for the expression of estrogen receptor (ER)-alpha, Ki-67 and p53. Apoptotic cells were identified using a TUNEL assay. A DNA sequence analysis of(More)
AIM Although overexpression of p53 is usually found in uterine serous carcinoma (USC), it is also found in some uterine endometrioid adenocarcinomas (UEA). This report describes the clinicopathological features of the UEA with overexpression of p53 with special reference to a prognostic significance of nuclear grade. MATERIAL AND METHODS(More)
In this case, a 27-year-old nulliparous woman with a pelvic multiple cystic mass was treated and found with ovarian mature cystic teratoma associated with port-site metastasis (PSM). Suspecting recurrence of mature cystic teratoma, a second laparoscopic surgery found a small mass, on the right under abdomen's peritoneal membrane, at the laparoscopic port(More)
OBJECTIVES Age-related changes in the expression of hormonal receptors have not been well examined in the fallopian tube (FT). We herein report the effect of menopause on the hormone receptors in ampullae of the FTs (AFTs), in comparison with cortical inclusion cysts (CICs) of the ovary. METHODS A total of 84 AFTs and 16 fimbriae of FTs, which were(More)
Dienogest is a novel progestin with potent oral progestational activity that inhibits the clinical symptoms of endometriosis. We herein evaluated the effect of dienogest on ovarian endometriotic cysts via immunohistochemistry. Ovarian endometriotic cyst specimens were collected from 12 patients treated with dienogest and 20 patients not treated with(More)
