Carcinosarcoma de ovario en paciente perimenopáusica / Ovarian carcinosarcoma in a perimenopausal woman

Resumen ANTECEDENTES: El carcinosarcoma de ovario, o tumor mixto de Müller, es una neoplasia infrecuente que representa alrededor del 1 al 4% de los carcinomas ováricos epiteliales. Su histología combina componentes sarcomatosos y carcinomatosos. CASO CLÍNICO: Paciente de 55 años, con diagnóstico de carcinosarcoma de ovario. Acudió a consulta debido a un sangrado uterino irregular y dolor abdominal. En la ecografía transvaginal se encontró una formación anexial sólida y heterogénea de 11.95 x 10.6 cm, con captación Doppler. El estudio se amplió con una tomografía axial computada (TAC) abdominopélvica y de tórax en la que se observó una tumoración en el lado izquierdo de 18 x 13 cm. Los marcadores tumorales se reportaron elevados: CEA 10.60, CA 125 91.3 y CA19.9 153 U/mL, con proteína HE-4 86.8 pmol/L, ligeramente disminuida. La laparotomía exploradora se completó con una cirugía para eliminar toda la carga tumoral. Se indicó quimioterapia con paclitaxel-carboplatino. El estudio histológico definitivo informó la existencia de una tumoración sólida-quística, compatible con un carcinosarcoma en el ovario izquierdo, con amplia diseminación peritoneal. A los 3 meses de la intervención, la paciente continuaba sin signos de recidiva. CONCLUSIONES: El carcinosarcoma es un tumor ginecológico poco frecuente pero muy agresivo; por su excepcional hallazgo aún no se dispone de criterios de tratamiento. Es decisivo fomentar investigaciones futuras acerca de los factores pronósticos y biomarcadores y desarrollar tratamientos dirigidos a las características moleculares de cada paciente.

Abstract BACKGROUND: Ovarian carcinosarcoma, or mixed Müllerian tumor, is a rare neoplasm that represents about 1 to 4% of epithelial ovarian carcinomas. Its histology combines sarcomatous and carcinomatous components. CLINICAL CASE: 55-year-old female patient with a diagnosis of ovarian carcinosarcoma. She consulted due to irregular uterine bleeding and abdominal pain. Transvaginal ultrasound showed a solid and heterogeneous adnexal formation measuring 11.95 x 10.6 cm, with Doppler uptake. The study was expanded with an abdominopelvic and chest computed axial tomography (CT) scan in which a tumor was observed on the left side measuring 18 x 13 cm. Tumor markers were reported elevated: CEA 10.60, CA 125 91.3 and CA19.9 153 U/mL, with HE-4 protein 86.8 pmol/L, slightly decreased. Exploratory laparotomy was completed with R0 surgery. Chemotherapy with paclitaxel-carboplatin was indicated. The definitive histological study reported the existence of a solid-cystic tumor, compatible with a carcinosarcoma in the left ovary, with extensive peritoneal dissemination. Three months after surgery, the patient continued without signs of recurrence. CONCLUSIONS: Carcinosarcoma is a rare but very aggressive gynecologic tumor; because of its exceptional finding no treatment criteria are yet available. It is crucial to encourage future research on prognostic factors and biomarkers and to develop treatments targeted to the molecular characteristics of each patient.

Preoperative serum levels of cancer antigen 125 and carcinoembryonic antigen ratio can improve differentiation between mucinous ovarian carcinoma and other epithelial ovarian carcinomas

OBJECTIVE: The main aim of this study was to evaluate cancer antigen 125 (CA125)/carcinoembryonic antigen (CEA) ratio (CCR), as a reliable marker to differentiate ovarian mucinous carcinoma from other epithelial ovarian carcinomas (EOCs), namely serous, clear cell, and endometrioid carcinomas. METHODS: Female patients suffering from different kinds of EOCs whom were subjected to elective surgery at the Gangnam Severance Hospital between January 2008 and December 2016, were included in this study. The serum levels of CA125 and CEA were assayed using commercially available kits per the manufacturer's instructions. RESULTS: The CCR in mucinous carcinoma (mean 32.1) was significantly lower than that of clear cell (mean 235.0) and endometrioid carcinoma (mean 427.0) in stage I (all P < 0.05). In stage II–IV, CCR in mucinous carcinoma (mean 37.6) was significantly lower than that of serous carcinoma (mean 148.0) (P < 0.01). The sensitivity and specificity of CCR in detecting mucinous carcinoma from other types of EOC was 75.0% and 77.5%, respectively in stage I and 100.0% and 84.4%, respectively in stage II–IV (both cut-off value < 90.7). CONCLUSION: The present results suggest that pretreatment CCR might provide higher specificity and clinically relevant information as a criterion for the differentiation between ovarian mucinous carcinoma and other types of EOC.

Expression and Clinical Significance of c-Src in the Epithelial Ovarian Carcinoma / 现代生物医学进展

Objective:we aim to determine the relationship between Cell sarcoma (c-Src) expression in patients with EOC and the disease phenotype.Methods:c-Src expression was evaluated using Western blotting analysis in 21 ovarian carcinomas and 4 normal ovarian tissues.Immunohistochemistry was used to evaluate c-Src expression in 134 ovarian carcinomas and 26 normal ovarian tissues.The association between c-Src expression and clinically pathologic characteristics were also assessed in these patients.Results:Our results indicated elevated c-Src protein in EOCs compared with that in normal tissues.The overexpression of c-Src was significantly associated with aggressive features,such as advanced disease stage,poor histological grade,lymph node metastasis,and tumor recurrence (P＜0.05).In addition,the overexpression ofc-Src is significantly associated with EOCs' prognosis.Conclusion:c-Src overexpression was significantly associated with the malignant biological behavior of tumor,suggesting c-Src as a potential preventive target in these patients.

The value of MSCTA in differential diagnosis between epithelial ovariancarcinoma and borderline epithelial ovarian tumor / 实用放射学杂志

Objective To evaluate the value of multislice spiral computed tomography angiography (MSCTA) in differential diagnosis between epithelial ovarian carcinoma (EOC) and borderline epithelial ovarian tumor (BOT).Methods The MSCTA images of 39 EOC patients and 23 BOT patients confirmed by surgical pathology were reviewed retrospectively.Main characteristics of tumor vessels were analyzed: the number of feeding arteries, the existence of dilated draining veins, whether the tumor vessels were tortuous, whether the distribution of tumor vessels were disturbed, and whether there were accompanying microaneurysms or arteriovenous malformations (AVMs).Results Two or more feeding arteries of the EOCs and BOTs were 89.7% (35/39) and 8.7% (2/23), respectively.Dilated draining veins were observed in 87.2% (34/39) of the EOCs and 4.3% (1/23) of the BOTs.The tortuosity of tumor vessels was observed in 97.4% (38/39) of the EOCs and 13.0% (3/23) of the BOTs.79.5% (31/39) of the EOCs and 8.7% (2/23) of the BOTs were complicated by microaneurysms, and 74.4% (29/39) of the EOCs and 4.3% (1/23) of the BOTs were complicated by AVMs.The characteristics of tumor vessels were significantly different between the two groups (P<0.01), with relatively high sensitivity and specificity.Conclusion MSCTA can better show the distribution, number and pattern of tumor vessels and is of great value in differential diagnosis between EOC and BOT.

Research Progress on Multiple Origins Theory of Epithelial Ovarian Carcinoma / 中国微创外科杂志

[Summary] Epithelial ovarian carcinoma has the highest fatality rate among gynecologic malignant tumors.Lacking of effective early diagnosis and screening method are the main reasons for its poor prognosis.There is a close relationship between the heterogeneity of epithelial ovarian carcinoma and the diversity of cancerous origins.According to the traditional theory, epithelial ovarian carcinoma derives from germinal epithelium at ovarian surface.The “secondary Mullerian system” theory has challenged above view.This“dualism” theory completely subverts the traditional one.However, both of the theories have their limitations.In recent years, the multiple origins theory of epithelial ovarian carcinoma has gradually become a hot point of discussion.

Therapeutic value of cisplatin-based neoadjuvant chemotherapy in patients with advanced epithelial ovarian cancer / 肿瘤

Objective: To explore the efficacy and safety of NAC (neoadjuvant chemotherapy) with docetaxel and cisplatin in patients with advanced epithelial ovarian cancer. Methods: Ninety-eight hospitalized patients with advanced ovarian cancer admitted to our hospital between January 2005 and July 2012 were randomly individed into NAC group (n = 48, receiving 2 cycles of NAC with docetaxel and cisplatin followed by cytoreductive surgery and 6 cycles of adjuvant chemotherapy with docetaxel and cisplatin) and the control group (n = 50, receiving cytoreductive surgery and 6-8 cycles of adjuvant chemotherapy with docetaxel and cisplatin). The mean blood loss, duration of operation and the rate of optimal cytoreductive surgery betweem the two groups were observed and compared. The side effects of chemotherapy and the survival were analyzed. Results: The amount of blood loss and the duration of operation of the NAC group were less than those of the control group (P < 0.05). The rate of optimal cytoreductive surgery of the NAC group was higher than that of the control group (85.4% vs 48.0%, P < 0.001). The median survival time and the median progression-free survival time were both longer than those of the control group (39 vs 31 months, P < 0.05; 27 vs 20 months, P < 0.05). The side effects of chemotherapy were not significantly different between the two groups. Conclusion: The NAC regimen with docetaxel and cisplatin can enhance the rate of optimal cytoreductive surgery, reduce the amount of blood loss, shorten the duration of operation, and improve the overall survival of patients with advanced epithelial ovarian cancer.

Trends in incidence and survival outcome of epithelial ovarian cancer: 30-year national population-based registry in Taiwan / 부인종양

OBJECTIVE: To investigate the changes of incidence and prognosis of epithelial ovarian cancer in thirty years in Taiwan. METHODS: The databases of women with epithelial ovarian cancer during the period from 1979 to 2008 were retrieved from the National Cancer Registration System of Taiwan. The incidence and prognosis of these patients were analyzed. RESULTS: Totally 9,491 patients were included in the study. The age-adjusted incidences of epithelial ovarian cancer were 1.01, 1.37, 2.37, 3.24, 4.18, and 6.33 per 100,000 person-years, respectively, in every 5-year period from 1979 to 2008. The age-specific incidence rates increased especially in serous, endometrioid and clear cell carcinoma, and the age of diagnosis decreased from sixty to fifty years old in the three decades. Patients with mucinous, endometrioid, or clear cell carcinoma had better long-term survival than patients with serous carcinoma (log rank test, p<0.001). Patients with undifferentiated carcinoma or carcinosarcoma had poorer survival than those with serous carcinoma (log rank test, p<0.001). The mortality risk of age at diagnosis of 30-39 was significantly higher than that of age of 70 years or more (test for trend, p<0.001). The mortality risk decreased from the period of 1996-1999 (hazard ratio [HR], 0.90; p=0.054) to the period after 2000 (HR, 0.74; p<0.001) as compared with that from the period of 1991-1995. CONCLUSION: An increasing incidence and decreasing age of diagnosis in epithelial ovarian cancer patients were noted. Histological type, age of diagnosis, and treatment period were important prognostic factors for epithelial ovarian carcinoma.

The relationship between the expressions of HuR and COX-2 in epithelial ovarian carcinoma / 中国综合临床

Objective To detect the expressions of HuR and COX-2 in epithelial ovarian carcinoma,and investigate the correlation of HuR and COX-2 expression. In addition, we attempt to seek the pathway to prevent the occurrence and development of epithelial ovarian cancer by combined analysis of various clinicopathologic characteristics. Methods The expressions of HuR and COX-2 in 68 epithelial ovarian carcinoma, 10 borderline ovarian tumors and 5 normal ovarian tissues were examined by S-P immunohistochemical method. The relationship of HuR and COX-2 expressions with clinicopathologic parameterwere evaluated by correlation analysis. Results(1) The expression of HuR in epithelial ovarian cancer tissue (76. 47% ,52/68) was significantly higher than that in borderline epithelial ovarian tumor tissues (30. 00% ,3/10) and normal ovarian tissues (0, x2 = 18. 873, Ps ＜ 0. 05), but there were no significant differences betweenthe expressions of HuR in borderline epithelial ovarian tumor and normal ovarian tissue(P ＞ 0. 05).(2) The positive expression rate of cytoplasmic HuR in epithelial ovarian carcinoma and borderline epithelial ovarian tumor were 45.60% (31/68) and 10. 00% (1/10) respectively,but normal ovarian tissues showed no staining of HuR. We found no significant differences between the expression of cytoplasmic HuR in epithelial ovarian carcinoma and borderline epithelial ovarian tumor or normal ovarian tissue(x2 = 7. 999 ,P =0. 018).(3) The positive expression rate of cytoplasmic HuR in epithelial ovarian carcinoma of FIGO stage Ⅲ - Ⅳ was significantly higher than that of stage Ⅰ - Ⅱ(56. 09% vs. 29. 63%, x2 = 4. 598, P = 0. 032). The positive expression rates of cytoplasmic HuR in epithelial ovarian carcinoma of histological grade 1,2,3 were 10. 00%,46. 67% ,57. 14% respectively, which showed significant difference in the comparison among the three groups (x2 =6. 627 ,P =0. 036). (4) The positive expression rates of COX-2 in epithelial ovarian cancer (67. 64%)and borderline epithelial ovarian tumor tissues (60. 00%) were significantly higher than that in normal ovarian tissues (0, Ps ＜ 0. 05), but we found no significant difference in the comparison between the expression of malignant and borderline ovarian tumors. Statistical analysis showed that the positive expression rate of COX-2 in epithelial ovarian carcinoma was correlated with FIGO stage and lymph node metastasis. (5)There was a significantly positive correlation between cytoplasmic HuR and COX-2 expressions in epithelial ovarian carcinoma. Conclusion The expressions of HuR and COX-2 increased in the epithelial ovarian carcinoma, and the cytoplasmic expression of HuR was significantly correlated with the expression of COX-2. These results suggested that increased cytoplasmic expression of HuR and COX-2 expression might play important roles in the initiation and development of epithelial ovarian carcinoma.

Expression of HER-2 and TOPO- Ⅱα in ovarian epithelial cancer and its clinical significance / 中国综合临床

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P ＜ 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps ＜ 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps ＞ 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps ＜ 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P ＜ 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

Uterine metastases in ovarian carcinoma: frequency and survival in women who underwent hysterectomy / 부인종양

OBJECTIVE: Possible reasons for hysterectomy in the initial surgical management of advanced invasive epithelial ovarian carcinoma (EOC) might be a high frequency of uterine involvement and its impact on survival. The aim of the present study was to describe the frequency of uterine involvement and its association with survival in an unselected population of EOC patients who underwent hysterectomy. METHODS: All incident cases of EOC diagnosed in Israeli Jewish women between March 1994 to June 1999, were identified within the framework of a nationwide case-control epidemiological study. The target population of the present report includes all stage II-IV EOC patients who had a uterus at the time of diagnosis. Of the 822 such patients, 695 fulfilled the inclusion criterion. Excluded were 141 patients for various reasons. The present analysis is based on the remaining 554 patients. RESULTS: Uterine involvement was present in 291 (52.5%) of the patients and it was macroscopic in only 78 (14.1%). The serosa was the most common site of isolated metastases. Multivariate analysis showed that advanced stage significantly increased the risk for uterine involvement. The overall median survival with any uterine involvement was significantly lower compared to those with no involvement (38.9 months vs. 58.0 months; p<0.001). CONCLUSION: There is an association between uterine involvement, whether macro- or microscopic, and lower survival even after hysterectomy although residual tumor could not be included in the analysis. Further studies are required to establish whether uterine involvement itself is an unfavorable risk factor or merely a marker of other unfavorable prognostic factors.

Expression and Relationship of OPN and MMP-9 in Epithelial Ovarian Carcinoma / 中国医科大学学报

Objective To study the expression and relationship of osteopontin (OPN) and matrix metalloproteinase-9 (MMP-9) in epithe-lial ovarian carcinoma. Methods Immunohistochemical staining S-P methods was used to detect the expression of OPN and MMP-9 in the samples of 60 epithelial ovarian carcinoma,20 benign ovarian tumor,20 borderline ovarian tumor and 10 normal ovarian tissue. Results The expression level of OPN and MMP-9 in epithelial ovarian carcinoma(109.86±21.51) were significantly higher than those in borderline ovarian tumor(45.81±8.93),benign ovarian tumor(11.86±3.01) and normal ovarian tissue(5.32±2.74). The expression level of OPN and MMP-9 related to the tumor grading,tumor stage and lymph node metastasis,while had no relationship with histological grading. There was significant positive correlation between OPN and MMP-9 in epithelial ovarian carcinoma (r = 0.80,P < 0.05). Conclusion The increased expression of OPN and MMP-9 may play an important role in the process of carcinogenesis, progression and differentiation of epithelial ovari-an carcinoma. OPN and MMP-9 may be a useful targets for treatment of ovarian carcinoma.

Expression of Wnt 1 and beta-catenin in epithelial ovarian cancer / 대한산부인과학회지

OBJECTIVE: We were trying to identify the expression of Wnt 1 and beta-catenin in normal ovarian epithelium and epithelial ovarian tumor. METHODS: We used archival formalin-fixed and paraffin-embedded tissues from Comprehensive Gynecologic Cancer Center and the Department of Pathology at Bundang CHA Hospital from 2000 to 2005. Immunohistochemical staining for Wnt 1 and beta-catenin was performed on the ovarian epithelial tissues. Statistical analyses were performed with SPSS 10.1 for Windows and significance was defined as P<0.05. RESULTS: Of 114 cases, the cases were composed of 54 carcinomas, 40 borderline tumors, 12 benign tumors and 8 normal control ovarian tissues. Abnormal nucleocytoplasmic expression of beta-catenin was found in 4 endometrioid carcinomas. The nuclear expression of beta-catenin was found especially in the components of the endometrioid carcinoma (28.6%, P<0.05). Wnt 1 was overexpressed in all 9 clear cell carcinomas, but not frequent in the other types of malignant tumors (P<0.05). We found a statistically significant correlation between beta-catenin nuclear localization and endometrioid carcinomas. And we found a significant correlation between Wnt 1 expression and clear cell carcinomas. CONCLUSION: It does not seem that Wnt 1 over expression directly provoke the nuclear localization of beta-catenin. But, deregulation of beta-catenin and Wnt 1 may play a role in the pathogenesis of ovarian epithelial carcinogenesis of endometriod carcinoma and clear cell carcinoma. Evaluating this avenue of regulation of beta-catenin and Wnt protein in ovarian epithelial carcinoma may provide a new direction for early diagnosis and treatment in ovarian epithelial carcinoma and provide opportunities for making a certain biomarkers.

Investigation of Human Epithelial Ovarian Carcinoma 3AO Models in Nude Mice / 医学研究杂志

Objective To study on the establishment of human ovarian cancer models with nude mice which can be investigated efficiently.MethodsHuman epithelial ovarian cancer 3AO cells cultured in vitro was injected by S.C.and I.P.in nude mice,so as to establish and observe human epithelial ovarian carcinoma models in nude mice.When the transplanted tumor grew big enough,the speciments of transplanted tumors were identified by histological and electron microscope observation and DNA content was analysed by flow cytometry.ResultsThe human ovarian cancer models with nude mice have been established successfully.There were many differences between the two kinds of models.The success rate of transplantation subcutaneously was 93.3%(14/15),whereas a little shorter rate was 86.7%(12/15) in transplantation peritoneally.ConclusionHuman ovarian cancer models with nude mice are easy to establish.They could display the invasive growth behavior and metastasis as same as human ovarian carcinoma.They are good models for experimental research of ovarian carcinoma.

Influence of all-trans retinoic acid on the methylation of the RARa gene in ovarian cancer cell line COC2 / 医学研究生学报

Objective: All-trans retinoic acid(ATRA) is a classic drug that can induce tumor differentiation,and its influence on the aberrant methylation of cancer cells has been studied insufficiently.The objective of this study was to observe the influence of ATRA on the methylation of the RARa gene promoter in ovarian cancer cell line COC2 and its relationship with the RARa expression.Methods: The ovarian cancer cell line COC2 was treated with different concentrations of ATRA for different times.Methylation specific PCR(MSP) and bisulfate sequencing methods were used to detect the changes in the methylation of the RARa promoter after ATRA treatment.RT-PCR was employed to observe the changes in the expression level of RARa mRNA.Results: Aberrant methylation of the RARa gene promoter was found in the ovarian cancer cell line COC2.ATRA treatment decreased the number of RARa promoter methylation sites in COC2 within a certain scope in a concentrationand time-dependent manner,and increased the expression of RARa mRNA.Conclusion: Aberrantly high methylation of the RARa promoter exists in the ovarian cancer cell line COC2;ATRA can partially reverse the methylation and increase the RARa mRNA expression.

Influence of all-trans retinoic acid on the invasive potential of epithelial ovarian carcinoma cell line COC2 / 医学研究生学报

Objective: To observe the influence of all-trans retinoic acid(ATRA) on the expressions of E-cadherin,heparanase and VEGF in epithelial ovarian carcinoma cell line COC2,and to investigate the anti-metastatic potential and possible action mechanism of ATRA.Methods: We used flow cytometry to examine the expressions of E-cadherin,heparanase and VEGF proteins in the epithelial ovarian carcinoma cell line COC2 treated with different concentrations of ATRA.Results: ATRA significantly increased the expression of E-cadherin and decrease that of VEGF and hepareanse in a dose-dependent manner.Conclusion: ATRA can inhibit cell proliferation,improve cell-cell adhesion and downregulate the expressions of VEGF and heparanse proteins,suggestive of an anti-angiogenic and anti-metastatic potential.

All patients received combination chemotherapy of abdomen and vein with CAP regime and TP regime after sections.Results:Total five year survival rates were 11% in epithelial ovarian carcinoma in stage Ⅲ. The 1-.3-.5-year survival rates of the cases which had less than 4 cycles of chemotherapy were lower than those ≥6 cycles, and the recurrent rates were higher than those ≥6 cycles. The 1-.3-.5-year survival rates of TP regime were higher than those of CAP regime,and the recurrent rates were lower than those CAP regime.Conclusions:There are many relationships between prognosis and residual tumor, nucmber of chemotherapy cycles or regime after resection,which influence results of recurrent ovarian cancer after repeated tumorectomy.

Prognostic factors of epithelial ovarian carcinoma in patients with age under 40 / 中国癌症杂志

Purpose:To study prognostic factors of younger women's eptihelial ovarian neoplasms.Methods: From Jan. 1980 to Dec. 1992, there were 86 cases of younger women's epithelial ovarian carcinoma in our hospital. We studied serveral prognostic factors retrospectively.Results:In this setting, 2 year survival rate were 79.07%, 5 year survival rate were 54.65%. There were 49 cases with stage Ⅰ and 41 cases with grade Ⅰ. No recurrence was found in 4 patients who preserved ovarian function. Cox model multifactor results showed that grade, residual tumor size and the method of surgery were prognostic factors( P 0 05). The pathological type, FIGO staging, grade, residual tumor size, the method of surgery were important factors according to unifactor analyze ( P

Epithelial Ovarian Carcinoma: Analysis of Prognostic Factors

One hundred and two patients with epithelial ovarian carcinomas treated at Yonsei University College of Medicine from January 1966 through December 1985 were retrospectively reviewed. Stage and tumor grade were found to be highly significant prognostic factors. Other important prognostic factors included residual tumor volume and transcapsular extension. Age and the presence of ascites were prognostic factors of marginal importance. The present study proposes that accurate surgical staging is mandatory at initial surgery and that tumor grading should be included in the FlGO classification of epithelial ovarian cancers. Improved surgical management to reduce the residual tumor volume is important for advanced tumor stage. In early tumor stages, more effective treatment should be reserved for patients with transcapsular extension. Prospective investigation is necessary for further subset analysis.
