A 47-year-old woman visited the surgical department, since she had a gradually growing and painful tumor both in an appendectomy scar and at an umbilical site. She underwent appendectomy at age 18 years, and noticed the tumor at age 22 years. Partial tumor resection was performed in that department, and the pathology revealed endometrioid adenocarcinoma. She was referred to our department for radical therapy. Tumors in the both sites were dissected together with some swelling lymph nodes in our department. A pathological diagnosis of the tumor in the umbilical site showed only benign endometriosis. In contrast, the tumor in the appendectomy scar showed benign endometriosis, atypical endometriosis and well differentiated endometrioid adenocarcinoma. Resected lymph nodes also contained endometrioid adenocarcinoma, and were diagnosed as metastases. It was concluded that the endometrioid adenocarcinoma in the tumor of the appendectomy scar was a malignant transformation arising from abdominal wall endometriosis from the pathological findings. Since the operation, adjuvant and maintenance chemotherapy with paclitaxel and carboplatin had been administered for 3 years. She is free of disease 3.5 years after the operation.展开更多

Methods: To detect the expression of PR and CD146 on 140 cases of paraffin-embedded tissue sections of endometrioid adenocarcinoma by using QDS double-labeling immunofluorescence. Results: The co-expression of PR and CD146 in the endometrioid adenocarcinoma can be detected by QDs double-labeling immunofluorescence, and there was no correlation between them (P > 0.05). Conclusion: QDs double-labeling immunofluorescence can detect the localization and co-expression of PR and CD146 in the endometrioid adenocarcinoma.展开更多

To determine overexpression of p53, EGFR, e-erbD-2 and e-erbB-3 in endometrioid carcinoma of the ovary and to evaluate the prognostic signiFtcance of these resdts, especially, eoexlsting overexpression of p53 and one of the member of type I growth factor receptor family. Methods. Overexpressions of the p53, EGFR, e-erbB-2 and e-erbB-3 protein were studied by immunohlstochemistry in paraffin-embedded tumor tissue from 28 patients with endometrioid carcinoma of the ovary. Results. 11 (39.3%), 13 (46.4%), and 14 (50. 0%) were stained positively with p53, e-erbB-2 and c-erbB-3 monoclonal ant/bodies. 13 (46. 4%) was stained positively with EGFR polyclonal antibody.There were no relationship between p53, EGFR, C-erbB-2, c-erbB-3 and histologic grade, lymph node metastasis. The percentage of tumors with over expression of p53, EGFR, C-erbB-2 and c-erbB-3 was higher in those with stage Ⅰ～Ⅱ tumors compared with those with stage Ⅰ, in patients with residual tumor after initial surgery compared with those without. A high survival rate was observed in patients without p53, EGFR, c-erbB-2 and c-erbB-3 overexpression respectively than those with. A highest survival rate was observed in patients with both p53 and one of EGFR, c-erbB-2 and c-erbB-3 negative compared with those both positive or either of both positive. Concltrsion. Overexpression of p53, EGFR, c-erbB-2 and C-erbB-3 resulted in a poorer prognosis respectively. Overexpression of both p53 and one of the EGFR, c-erbB-2 and e-erbB-3 is a worse prognostic indicator in patients with endometrioid carcinoma of the ovary.展开更多

However, the role of DUSP1 medroxyprogesterone （MPA） are still unclear. phosphatase I （DUSPI） was differentially expressed in endometrioid in EEA progression and the relationship between DUSPI and Methods： The expression of DUSPI in EEA specimens was detected by immunohistochemical analysis. The effect of DUSPI on cell proliferation was analyzed by Cell Counting Kit 8 and colony formation assay, and cell migration was analyzed by transwell assay. MPA-induced DUSPI expression in EEA cells was measured by Western blot. Results： DUSPI expression was deficient in advanced International Federation of Gynecology and Obstetrics stage, high-grade and myometrial invasive EEA. In EEA cell lines （HeclA, Hecl B, RL952, and Ishikawa）, the DUSP1 expression was substantially higher in lshikawa cells than in other cell lines （P 〈 0.05）. Knockdown ofDUSP I promoted lshikawa cells proliferation, migration, and activation of mitogen-activated protein kinases/extracellular signal-regulated kinase （MAPK/Erk） pathway. MPA-induced DUSP1 expression and inhibited MAPK/Erk pathway in Ishikawa cells. Conclusions： Our data suggest that DUSP1 deficiency promotes EEA progression via MAPK/Erk pathway, which may be reversed by MPA, suggesting that DUSP I may serve as a potential therapeutic target for the treatment of EEA.展开更多
