A study on clinicopathological characteristics of ovarian masses / 대한산부인과학회지

OBJECTIVE: The aim of this study was to know the clinicopathological characteristics that help to make a decision about diagnosis and treatment of ovarian masses in Korean women. METHODS: Women who were undergone operations and histopathologically confirmed as ovarian masses at Inje University Busan Paik Hospital and Donrae Paik Hospital from January of 1997 to June of 2009 were enrolled in this study. Distribution according to histopathological types and ages were analyzed. RESULTS: Of the 2875 cases, there were 1078 cases (37.5%) of non neoplastic masses and 1797 cases (62.5%) of neoplastic masses. In the neoplatic masses, there were 1286 cases (44.7%) of benign tumors, 140 cases (4.9%) of borderline tumors and 371 cases (12.9%) of malignant tumors. Endometriomas were most common tumors (644 cases, 59.7%) among non-neoplastic masses. Mature cystic teratomas were the most common tumors (598 cases, 46.5%) among benign tumors. Mucinous cystadenomas were the most common types (105 cases, 75.0%) among borderline tumors. Epithelial ovarian cancers were the most common types (267 cases, 72.0%) among malignant tumors. As the result of age distribution, mature cystic teratomas were the most common types of the women of the first and second decade, endometriomas were the most common types of the women of the third and fourth decade, and benign epithelial tumors were the most common types of the women of fifth and after sixth decade. CONCLUSION: Taken as a whole, neoplastic ovarian masses were more common than non-neoplastic masses, but most common ovarian mass was endometrioma which is non-neoplastic mass.

Comparisons of clinicopathologic characteristics and prognostic factors between squamous cell carcinoma and adenocarcinoma of the uterine cervical cancer patients underwent radical hysterectomy and pelvic lymphadenectomy / 부인종양

OBJECTIVE: To compare clinicopathologic characteristics and prognostic factors between squamous cell carcinoma (SCC) and adenocarcinoma (AC) of the uterine cervix. METHODS: We reviewed medical records and pathologic reports of 568 patients with SCC and 78 patients with AC who underwent radical hysterectomy and pelvic lymphadenectomy from January 1988 to December 2004. We analyzed clinicopathologic factors and 5-years survival rate (5-YSR), and than compared 5-YSR between SCC and AC according to clinicopathologic factors. RESULTS: At the stage I, the incidence of AC (82.0%) was more than SCC (69.6%) and at the stage II, the incidence of SCC (30.4%) was higher than AC (18.0%). The rate of lymph-vascular space invasion was higher in SCC (28.2%) than AC (15.4%). The 5-YSR was not different between SCC (85.7%) and AC (86.9%). In multivariate analysis, depth of invasion, resection margin, pelvic lymph node metastasis were independent prognostic factors in SCC and FIGO stage, pelvic lymph node metastasis were independent prognostic factors in AC significantly. At the 5-YSR between SCC and AC, the prognosis of AC (50.0%) was poorer than SCC (78.0%) in the case of the one pelvic lymph node metastasis (p=0.0632). CONCLUSION: The FIGO stage and lymph-vascular space invasion were significant different in clinicopathologic characteristics between SCC and AC. The prognosis of AC was poorer than SCC in the case of the one pelvic lymph node metastasis (p=0.0632). But, the overall 5-YSR was not different between SCC and AC.

Expression of HER-2/neu Oncoprotein in Epithelial Ovarian Cancer / 대한산부인과학회지

OBJECTIVE: To evaluate the significance of the expression of HER-2/neu oncoprotein as a prognostic factor, we retrospectively examined its overexpression rates in epithelial ovarian cancer and their relationships with prognostic factors. METHODS: Immunohistochemistry for Her-2/neu oncoprotein was performed on formalin-fixed, paraffin-embedded tissues from 45 epithelial ovarian cancer operated between 1999 and 2002. We analyzed relationships between the overexpression of HER-2/neu oncoprotein and prognostic factors including age, histologic type, surgical stage, residual tumor > or =2 cm, and recurrence. RESULTS: The rate of overexpression of HER-2/neu oncoprotein in epithelial ovarian cancer was 31.1% (14/47). The overexpression of HER-2/ neu oncoprotein showed associations with residual tumor > or =2 cm (p=0.049) and recurrence (p=0.029) in univariate analysis. But, there were no associations between the overexpression of HER-2/neu oncoprotein and overall survival. CONCLUSION: The overexpression of HER-2/neu oncoprotein was associated with residual tumor and recurrence in univariate analysis, but appeared to have no prognostic significance for overall survival of epithelial ovarian cancer. Further and larger prospective studies using multivariate analysis are necessary to establish the clinical applicability of these observations.
