Hepatoid adenocarcinoma is a rare and unusual tumor in the female genital tract. Hepatoid adenocarcinoma resembles hepatocellular carcinoma morphologically but develops in extrahepatic organs, and usually demonstrates foci of adenocarcinoma of the primary organ. Tumor cells often stain positive for anti-α-fetoprotein antibody, and may be associated with elevated serum α-fetoprotein, which may be useful as a tumor marker to guide treatment. There is little reliable information to guide clinical management of these unusual tumors and prognosis is poor despite multi-modal treatment. This report describes the diagnosis and treatment of this tumor in a postmenopausal woman. [ABSTRACT FROM AUTHOR]

Primary squamous cell carcinoma arising from the fallopian tube (SCCFT) is extremely rare with only six reported cases. We report a case of primary SCCFT accompanied by multifocal pyloric glandular metaplasia in the genital tract. An accompanying review of the literature describes the characteristics of this rare histological subtype invading into the muscular layer of the fallopian tube to involve adjacent pelvic organs, while the most common serous type tends to spread into the abdominal cavity through tubal ducts. Due to the low response rate of adjuvant therapies, the 5-year survival rate of patients bearing primary SCCFT at stage II-IV is very poor, only accounting for 25%. All patients were alive without disease where optimal resection had been successfully achieved. These findings imply that radical tumor resection is mandatory for satisfactory treatment of primary SCCFT. [ABSTRACT FROM AUTHOR]

Aim: The expression of Dkk-3, as a number of the Dkk family was different in different cancer. Because Dkk-3 encodes a secreted protein, we investigated whether the Dkk-3 protein is secreted into the sera of patients with gynecological cancer. Material & Methods: The levels of Dkk-3 protein were assessed by enzyme-linked immunosorbent assay in the sera of 104 patients with gynecological cancer: 36 with ovarian, 40 with cervical and 28 with endometrial cancers. Results: The serum levels of Dkk-3 protein in patients with ovarian cancer [25.54 (7.99) pg/mL] was lower than in normal individuals [42.08 (14.89) pg/mL] ( P = 0.000). But serum levels of Dkk-3 protein in patients with cervical [166.39 (300.68) pg/mL] ( P = 0.013) and endometrial cancers [73.64 (23.36) pg/mL] ( P = 0.000) were higher than in normal individuals. The serum levels of Dkk-3 protein were associated with clinical stage in patients with cervical and endometrial cancers. In patients with ovarian cancer, the serum levels of Dkk-3 protein were associated with lymphatic metastasis. In patients with cervical cancer, the serum levels of Dkk-3 protein were associated with tumor diameters. Conclusion: Dkk-3 protein detection using enzyme-linked immunosorbent assay as molecular markers can contribute to detection and diagnosis of gynecological cancer, especially for ovarian cancer and endometrial cancer.
