The clinicopathological relationship of E2F-1 and Ki-67 expression in endometrial cancer / 대한산부인과학회지

OBJECTIVE: The aim of this study was to evaluate the correlation of E2F-1 and Ki-67 expression with clinicopathological prognostic factors. METHODS: Retrospectively, endometrial cancer slide samples (n=71) were analyzed. E2F-1 and Ki-67 were evaluated using immunohistochemical staining. And as a control (n=21), endometrial tissues were obtained by hysterectomy with benign gynecologic disease. RESULTS: Of 71 cases, the positive E2F-1 expression was 53.5% (38/71) in endometrial cancer. The expression of E2F-1 showed a remarkable positive correlation with myometrial invasion (P=0.001) and lymphovascular invasion (P=0.000). The Ki-67 labeling index was 30.56+/-25.67 in endometrial cancer and 9.38+/-8.35 in normal endometrial tissues (P=0.001). The Ki-67 labeling index showed positive correlations with increased tumor size (P=0.046, gamma=0.238), positive lymph node metastasis (P=0.001, gamma=0.396), cervical invasion (P=0.000, gamma=0.404) and lymphovascular tumor invasion (P=0.000, gamma=0.597). There was a positive correlation between E2F-1 and Ki-67 expression (P=0.000, gamma=0.734). CONCLUSION: The Ki-67 expression seems to be related with tumor invasiveness and growth in endometrial cancer and shows a remarkable positive correlation with E2F-1. The E2F-1 expression seems to be not related as a direct prognostic factor but related with tumor invasiveness and growth in endometrial cancer.

A case of inguinal endometriosis in the absence of previous gynecologic surgery / 대한산부인과학회지

Endometriosis is a common gynecologic disease, it occur not only pelvic organ but also anywhere in human body. However inguinal endometriosis is a very rare condition, its incidence is 0.4% of entire endometriosis. Most of inguinal endometriosis are found as inguinal masses in women in 30s and 40s who have history of gynecologic surgery. Majority of the cases are accompanied with pelvic endometriosis. Authors report a case of inguinal endometriosis in patients who has no history of gynecological surgery.

The clinicopathological relevance for the expression of cyclin E, CDK2, and p27 in endometrial carcinoma / 대한산부인과학회지

OBJECTIVE: The aim of this study was to evaluate the clinicopathological relevance for the expression of cyclin E, CDK2 and p27 in endometrial carcinoma. METHODS: With a retrospective review, slide samples (n=71) were analyzed. All patients had been treated with hysterectomy from January 1998 to December 2006. The expression of cyclin E, CDK2 and p27 were analyzed using immunohistochemical staining. RESULTS: Of 71 cases, the positive expression was cyclin E; 28 cases (39.4%), CDK2; 29 cases (40.8%). The expression of cyclin E showed positive correlation with lymph node metastasis (P=0.033) and estrogen receptor. The expression of CDK2 showed positive correlation with estrogen receptor (P=0.000). The negative expression of p27 was 42 cases (59.2%) and showed no correlation with other clinicopathological factors. Cyclin E overexpression with loss of p27 expression showed positive correlation with advanced stage (P=0.002), lymphovascular invasion (P=0.030) and lymph node metastasis (P=0.002). CONCLUSION: Cyclin E overexpression with loss of p27 expression could be an useful negative prognostic factors for endometrial carcinoma.

A Case of Advanced Gastric Cancer Diagnosed by Endoscopy Performed in the Second Trimester due to Persistent Nausea and Vomiting / 대한주산의학회잡지

Gastric cancer is rarely associated with pregnancy and its incidence is reported to be 0.1%. The dilemma in the treatment of this rare occasion is that it is usually diagnosed at an advanced stage. The most common reason for delayed diagnosis is that early symptoms of gastric cancer, such as nausea, vomiting and epigastric discomfort, are nonspecific and usually misinterpreted as those related to pregnancy. Clinicians' reluctance to request diagnostic studies is another reason for delayed diagnosis. So these make the prognosis much worse. We must consider the rare possibility of gastric cancer in case of persistent nausea and vomiting. We report a case of advanced gastric cancer diagnosed by gastroscopic examination performed in the second trimester because of persistent nausea and vomiting.

The clinicopathological relevance of Poly (ADP-ribose) polymerase (PARP) expression in epithelial ovarian cancer / 대한산부인과학회지

OBJECTIVE: To evaluate the clinicopathological implication of poly (ADP-ribose) polymerase (PARP) expression in epithelial ovarian cancer. METHODS: Retrospectively, slide samples (n=72) were analyzed. PARP expression was analyzed using immunohistochemical staining. RESULTS: Of 72 cases, positive PARP expression were 27 cases (37.5%). PARP expression showed negative correlation with FIGO stage (p=0.004) and mitotic count (p=0.010), but showed no correlation with grade (p=0.053), tumor size (p=0.301), Ki-67 LIs (p=0.986), p53 positivity (p=0.414), and bcl-2 positivity (p=0.413). CONCLUSION: PARP expression showed negative correlation with advanced stage and mitoses in epithelial ovarian cancer. Therefore PARP expression could be a new prognostic factor in epithelial ovarian cancer.
