Uterine extra gastrointestinal stromal tumor presenting as intramural leiomyoma.

Extra gastrointestinal stromal tumors (EGIST) are reported in different sites and organs. This tumors are rare in gynecologic apparatus. Here the authors report an uterine unique tumor represented as intramural leiomyoma. Because of different treatment options, clinicians should be aware of this rare tumor which may be located in uterus and confused with a smooth muscle tumor.

Vulval pruritus: the experience of gynaecologists revealed by biopsy.

Pruritus of the vulva is a common symptom among patients attending to outpatient clinics. In the present study, we aimed to assess pathologies causing vulval pruritus in the reliability of biopsy in a tertiary referral centre. A total of 137 patients undergoing vulval colposcopy because of vulval pruritus were reviewed from the hospital records retrospectively. The mean age of the patients was 47.61 ± 11.88 years and 36.5% of the patients were postmenopausal. In 101 (73.7%) of the patients, macroscopic lesions were present. In 88 (64.2%) of the patients, tolidine-positive stained areas were determined under colposcopy. In total, 68 (49.6%) of the lesions were plain, whereas 51 (37.2%) of them were depigmented. Lichen simplex chronicus, lichen sclerosis and chronic inflammation were the major pathologies associated with vulval pruritus (25.5%, n = 35; 20.4%, n = 28; 14.6%, n = 20). In conclusion, several pathologies out of vulvovaginal candidiasis may lead to vulval pruritus and clinicians should be aware of the importance of biopsy in determining the underlying pathology.

Borderline ovarian tumors: outcomes of fertility sparing surgery.

AIM: Borderline ovarian tumors(BOT) account for ten to 20 percent of all epitelial ovarian carcinomas and often occur in reproductive ages. The aim of this study was to evaluate the clinical and reproductive outcomes of patients who were diagnosed with BOT and underwent fertility sparing surgery. MATERIALS AND METHODS: Patients younger than 40 years who underwent fertility sparing surgery for BOT from 2004 to 2012 were reviewed retrospectively and were evaluated according to the reproductive and clinical outcomes. RESULTS: Twenty-eight patients younger than 40 years with BOT underwent fertility sparing surgery. Median follow up time was 42 +/- 28.1 months. During the follow up period, two patients (7.1%) developed recurrence at 35 and 36 months, respectively. Five (17.9%) out of 28 patients became pregnant during the follow up period. CONCLUSION: Fertility sparing surgery should be the first choice for the treatment of BOT in patients who wish to preserve fertility.

Surgical intervention for adnexal masses during pregnancy.

We aimed to evaluate the influence of surgical intervention on gestational and neonatal outcomes in women who underwent elective surgery in the second trimester of gestation because of an adnexal mass. We retrospectively reviewed the hospital records of women who underwent elective surgery for adnexal masses in the second trimester of gestation between 2006 and 2012. The ages of the women ranged between 17 and 33 years. Eight women underwent a laparotomy, and one woman, who aborted on the day of the operation, underwent a laparoscopy. Dermoid cysts, cystadenoma and borderline ovarian tumours were present in four, two and two of the women, respectively. Eight women had no complications after surgery and delivered healthy newborns at term. We concluded that elective surgery on an adnexal mass in the second trimester of gestation is safe for both the mother and the fetus.

Platelet volume as a parameter for platelet activation in patients with endometrial cancer.

The objective of this study was to use mean platelet volume (MPV) as a measure of platelet activation in patients with endometrial adenocarcinoma and healthy controls. There was a total of 310 patients with endometrial adenocarcinoma retrospectively evaluated and 250 healthy controls. Preoperative haemoglobin, platelet counts and mean platelet volume were evaluated and statistical tests were conducted to determine the differences among early and advanced disease groups and controls. Median haemoglobin (13.0 vs 13.3 g/dl) and platelet count (282,000 vs 280,000/µl) values were similar in patients with endometrial adenocarcinoma and healthy controls (p > 0.05). Subjects with endometrial cancer exhibited slightly higher MPV than the control group (8.4 fl vs 8.2 fl) (p = 0.048). In patients with advanced-stage endometrial cancer, haemoglobin was significantly lower (p < 0.05) and MPV was significantly higher (p < 0.05) than in either patients with early-stage endometrial cancer or the control group. It was concluded that MPV was found to be a marker for predicting advanced-stage endometrial cancers.

The relationship between urogenital symptoms and climacteric complaints.

OBJECTIVE: To evaluate the relationship between urogenital symptoms and climacteric complaints, including anxiety, depression, somatic, vasomotor and sexual subscores according to the Greene Climacteric Scale (GCS). METHODS: We retrospectively reviewed the records of 1278 patients and the 908 patients who fulfilled the inclusion criteria were included in the study. The relationships were evaluated between GCS and vaginal symptoms, including vaginal pain, dyspareunia, itching, discharge, burning, dryness, and postcoital bleeding, and urinary symptoms, including dysuria, frequency, nocturia and incontinence, by using univariate and multivariate analyses. RESULTS: Among vaginal symptoms, somatic and sexual scores and, among urinary symptoms, anxiety and somatic scores were found to be the most associated factors. Of the vaginal symptoms, the highest odds ratios for somatic score and sexual score were found to be 2.21 (95% confidence interval (CI) 1.69-2.88, p < 0.001) and 2.08 (95% CI 1.70-2.56, p = 0.029), respectively. Multivariate logistic regression analyses for urinary symptoms revealed that the highest odds ratios for anxiety, somatic, depression and sexual scores were 1.53 (95% CI 1.20-1.95, p = 0.001), 1.92 (95% CI 1.38-2.66, p = 0.01), 1.47 (95% CI 1.11-1.94, p = 0.007), and 1.28 (95% CI 1.06-1.55, p < 0.001), respectively. CONCLUSIONS: There is a strong relationship between urogenital symptoms and GCS subscores. Therefore, clinicians should be aware of urogenital problems in the presence of severe climacteric symptoms and this may provide earlier treatment for urogenital complaints.

Prediction of suboptimal cytoreduction of epithelial ovarian carcinoma by preoperative computed tomography.

In an aim to evaluate the diagnostic efficacy of preoperative abdominal-pelvic CT for the prediction of suboptimal cytoreduction of epithelial ovarian carcinoma (EOC) at primary surgery, CT scans of 48 patients who underwent primary surgery for EOC were retrospectively analyzed. The presence of at least one of the following CT findings: multiple implants > 1 cm in maximum diameter in the mesenteria of the small or large intestines, porta hepatis or intersegmental fissure or on the hepatic surface, diaphragmatic peritoneum, gastrohepatic or gastrosplenic ligaments or the extension of tumor infiltration > 2 cm on the omentum towards the spleen or stomach or the intestines encased by the tumor > 2 cm, diffuse peritoneal thickening or invasion of the lateral pelvic wall > 1 cm or multiple lymph nodes > 1 cm at the cardiophrenic and suprarenal levels were accepted as the critical markers for predicting suboptimal cytoreduction. Suboptimal surgery, defined as leaving a residual tumor mass > 1 cm, was determined in 18 (37.5%) patients. CT predicted suboptimal cytoreduction with 83.3% (15/18) sensitivity, 90% (27/30) specificity and 87.5% (42/48) accuracy. PPV and NPV values were 83.3% (15/18) and 90% (27/30), respectively. These results suggested that preoperative CT could successfully predict suboptimal surgery in patients with EOC.

Comparison of histopathologic classification and surgical stage by cytokeratin 8 and cytokeratin 18 in endometrial cancer.

PURPOSE OF INVESTIGATION: The aim of the study was to show the role of the cytoskeletal proteins CK8 and CK18 in endometrial cancer invasion and to histopathologically classify endometrial cancer patients. METHODS: This study was a prospective analysis of 49 histologic samples of consecutively surgically operated endometrial cancer patients. After histopathologic classification the most invasive tumor area was selected for immunohistochemistry. Monoclonal antihuman keratin Ab-4 and keratin Ab-1 were applied. RESULTS: CK8 and CK18 stained tumoral tissue and tumoral cell debris in the lymphovascular space were significantly correlated with stage (p < or = 0.005). CONCLUSIONS: To understand the causes of early treatment failure in endometrial cancer patients, further studies are needed to show the role of enhancing factors of endometrial cancer invasion.

Prognostic significance of fascin expression in endometrioid carcinoma.

PURPOSE OF INVESTIGATION: Actin bundling protein fascin has been previously associated with tumor progression in human cancers. We evaluated whether fascin also plays a role in endometrioid carcinomas. METHODS: Cases of 28 proliferative and hyperplastic endometrium and 43 endometrioid carcinomas were examined by immunohistochemistry using antihuman fascin antibody. RESULTS: Weak fascin expression in glandular epithelium was observed in 39% of non-neoplastic samples and various degrees of fascin expression were observed in 74% of neoplastic samples. The number of positively stained samples and intensity of epithelial staining were significantly higher in endometrioid carcinoma compared to the non-neoplastic group (p < 0.001). The number of positively stained samples and total fascin scores of stroma were significantly higher in proliferative and hyperplastic endometrium biopsies compared to the endometrioid carcinoma (p < 0.001). Higher grade endometrioid carcinoma cases had significantly increased total epithelial fascin scores (.042, p < 0.05). There was also a significant difference between tumor grade and patient survival (.040, p < 0.05). There was a significant correlation between microvessel count and disease-free survival (r = .412, p = .006). In the proliferative and hyperplastic endometrial biopsies microvessels stained homogeneously in all cases (28/28), but in the endometrioid carcinoma group eight out of 43 cases showed heterogeneous fascin staining of microvessels. The difference was significant (.019, p < 0.05). CONCLUSIONS: Our study supported the dynamic role of actin bundling protein fascin in generating and maintaining endometrial neoplasms. It also showed that in the development of neoplasia, stromal fascin expression decreases but epithelial fascin expression up-regulates.

Actin bundling protein fascin expression in ovarian neoplasms: comparison of histopathologic features of tumors obtained by the first and secondary cytoreduction surgeries.

PURPOSE OF INVESTIGATION: The aim of the study was to compare the fascin expression pattern and histopathologic features of malign epithelial ovarian tumors obtained by the primary and secondary surgeries. METHODS: The samples of 94 epithelial ovarian carcinomas, 35 secondary surgeries for ovarian carcinomas, 13 borderline epithelial ovarian tumors, 25 cystadenomas and four normal ovarian tissues were stained by means of fascin immunohistochemistry. Secondary surgeries included in the study were secondary cytoreduction at the time of second-look laparotomy (SLL), interval debulking surgery after neoadjuvant chemotherapy or secondary cytoreductive surgery in patients with recurrent epithelial ovarian carcinoma. RESULTS: Mean rank value of the stromal fascin score was higher in 94 cases of malign epithelial ovarian carcinomas than borderline epithelial tumors, cystadenomas and normal ovaries (.000, p < 0.001). There was no significant difference in terms of total epithelial fascin score (.685, p > 0.05) and total stromal fascin score (.572, p > 0.05) between the primary and the secondary surgeries of epithelial ovarian carcinomas. CONCLUSIONS: Regarding the results of stromal fascin expression in 94 epithelial ovarian carcinomas, we hypothesized that cell-matrix interaction was an important step in the progression of malign epithelial ovarian neoplasms. Our study showed that the initial tumorigenic phenotype did not change with time and use of cisplatinum-based combination chemotherapy. Further studies with close follow-up of patients are necessary to reveal the role of fascin on matrix degradation mechanisms which might be the cause of the recurrences in ovarian neoplasms.

The role of actin bundling protein fascin in the progression of ovarian neoplasms.

PURPOSE OF INVESTIGATION: The aim of the study was to investigate the role of fascin in tumor progression and to investigate the role of fascin on endothelial cell migration and angiogenesis in ovarian neoplasms. METHODS: In the study, 94 malign epithelial ovarian neoplasms, 13 borderline epithelial ovarian neoplasms, 25 serous and mucinous cystadenomas and four normal ovarian tissues were examined by means of immunohistochemistry, using monoclonal antihuman fascin antibody, clone IM20. RESULTS: Total stromal fascin score in cases of borderline and malign epithelial ovarian tumors was significantly higher compared to normal ovaries and benign epithelial ovarian tumors (.000, p < 0.001). There was no statistically significant difference in terms of total epithelial fascin scores of samples between groups (.080, p > 0.05). Presence of vascular invasion (.000, p < 0.001), psammomatous calcifications (.001, p = 0.001), and lymphocytic infiltration (.000, p < 0.001) were significantly higher in malign neoplasms. There was no significant difference in terms of mean microvessel count and homogeneous or heterogeneous fascin expression of microvessels between the benign and malign groups (respectively p = .228 and p = .143). CONCLUSIONS: This study suggests that up-regulation of fascin in tumoral tissue may promote invasion of ovarian carcinoma by cell-matrix adhesion.

Mixed serous and endometrioid carcinoma of the fallopian tube: a case report with literature review.

Malignant neoplasms of the fallopian tube are the rarest of the gynecologic cancers. The frequency of histologic subtypes has been difficult to ascertain from the literature because most authors have not classified these tumors according to their cell types. Papillary serous adenocarcinoma appears to be the most common histologic type. On the contrary, mixed cell types of fallopian tube carcinoma have rarely been reported in the literature. A case of mixed serous and endometrioid carcinoma of the fallopian tube is presented and the related literature is reviewed.

Genetic imbalances in endometrial hyperplasia and endometrioid carcinoma detected by comparative genomic hybridization.

OBJECTIVE: To evaluate the sequential genomic copy alterations related to the development of precursor lesions and endometrioid-type endometrial carcinomas, and its association with cellular atypia. STUDY DESIGN: Paraffin-embedded tissue specimens from 32 cases of endometrial hyperplasia, 15 of endometrial carcinoma, and 20 of normal endometrial tissue were retrospectively evaluated by the comparative genomic hybridization (CGH) technique. The average number of copy alterations (ANCA) index was used to define the incidence of genomic imbalances in each tissue group. Identified sequential genetic abnormalities were compared with the final histopathological diagnosis and the cellular atypia. RESULTS: Detectable and consistent chromosomal imbalances were found in 13 hyperplasia and 9 carcinoma specimens. There was a significant correlation between ANCA value and degree of cellular atypia and tumor grade. While 1p36-pter, 20q deletions, and 4q overrepresentation were the most prevalent imbalances detected in both complex hyperplasia and complex atypical hyperplasia, 17q22-qter deletion and amplification of 2p34 were only seen in hyperplasia with atypical cells. Overrepresentations of chromosomes 8q, 1q, and 3q are the most frequent aberrations in endometrial carcinomas, but were absent from all the precursor lesions except one. Underrepresentations of chromosomes 1p36-pter and 10q are the other commonly seen aberrations in carcinomas, the latter being more frequent in moderately differentiated than in poorly differentiated lesions. CONCLUSIONS: Different patterns of chromosomal aberrations are seen in precursor lesions than in endometrial carcinomas, except for the loss of 1p36-pter. The presence of 1p deletion in both endometrial hyperplasia and cancer specimens suggests that this is an early event in the development of carcinoma. These results support a stepwise mode of tumorigenesis with accumulation of a series of genomic copy alterations in endometrial carcinogenesis.

Fascin, an actin-bundling protein expression in cervical neoplasms.

PURPOSE OF INVESTIGATION: Our objectives were (1) to examine expression of fascin in cervical tissues with chronic inflammation, intraepithelial neoplasms and invasive carcinomas, and (2) to investigate the role of fascin on endothelial migration and angiogenesis in cervical neoplasms. METHODS: In this study we investigated by means of immunohistochemistry fascin expression in 92 cervical biopsy samples representative of chronic inflammation (n=13), squamous intraepithelial lesions (SILs, n = 33) and invasive carcinomas (n = 46). RESULTS: Various degrees of fascin expression were observed in 94% of the samples of SILs, in 67% of the samples of invasive cervical carcinoma and in 69% of the samples of chronic inflammation. Total epithelial fascin scores of samples were significantly higher in high-grade (H)SILs compared to low-grade (L)SILs, invasive carcinoma and chronic inflammation of the cervix (p < 0.05). Mean microvessel count was 55.00 +/- 5.17 in HSILs, 40.76 +/- 3.57 in LSILs, 37.11 +/- 2.91 in carcinoma and 25.69 +/- 3.98 in chronic inflammation. We found a significantly higher microvessel count in HSILs compared to invasive carcinoma and chronic inflammation (respectively, p = .004, p = .000). CONCLUSION: Epithelial fascin expression up-regulated when the malignant tumor cell phenotype had occurred in the cervix. Similarly, microvessel count increased with the beginning of cervical tumorigenesis.

Massive ovarian edema: a case report.

Massive ovarian edema is considered a non-neoplastic lesion characterized by a tumor-like enlargement of one or occasionally both ovaries secondary to an accumulation of edema fluid within the stroma. It is an uncommon entity that usually leads to oophorectomy as an unnecessary treatment in children, adolescents and young women. A diagnostic wedge resection with subsequent frozen section is essential. A definitive diagnosis of massive ovarian edema can not be made on preoperative imaging. In this article a case of massive ovarian edema in a 15-year-old female thought to be a solid neoplasm in the preoperative period is described.

Sclerosing stromal tumor of the ovary associated with Meigs' syndrome: a case report.

Sclerosing stromal tumors of the ovary are distinct, but rare benign neoplasms. These tumors appear solid and are very vascular giving the impression of malignant tumors. They occur mostly in young women. Morphologically they have distinct characteristics which differentiate them from other stromal tumors. Benign ovarian tumors associated with Meigs' syndrome are rare. In this article a case of ovarian sclerosing stromal tumor associated with Meigs' syndrome in a 17-year-old women is described and the differential diagnosis is also discussed.

Computed tomography findings of primary serous papillary carcinoma of the peritoneum in women.

With the aim to describe preoperative computed tomography (CT) findings, the clinical, histopathological, and CT findings of the 12 consecutive patients with a confirmed diagnosis of primary peritoneal serous papillary carcinoma (PPSPC) were retrospectively evaluated. Of the 12 patients with a mean age of 57.5 +/- 10.3 years, ten (83.3%) were postmenopausal. Serum Ca-125 levels were elevated in all patients. Ten (83.3%) had Stage III and two (16.7%) patients had Stage IV disease and none of the excised ovaries had deep parenchymal involvement. The most common CT findings were the omental (n = 11), mesenterial (n = 11) and parietal peritoneal involvements (n = 10), and variable amount of ascites (n = 10). Pelvic peritoneal involvement in four (33.3%) patients was so extensive that it resembled a mass in the Douglas pouch. Thickening of the wall of gastrointestinal viscera (n = 9), lymphadenopathy (n = 5) and pleural effusion (n = 5) were the other CT findings and calcification was seen in only three (25.0%) patients. Although, none of them was characteristic, CT features of diffuse peritoneal, omental and mesenterial involvement especially in middle-aged or elderly postmenopausal women with normal-size ovaries in the absence of an identifiable primary site in conjunction with elevated level of serum CA-125 should suggest the possibility of PPSPC.

Prognostic value of matrix metalloproteinase-9 (gelatinase-B) expression in epithelial ovarian tumors.

PURPOSE OF INVESTIGATION: To determine the expression of matrix metalloproteinase-9 (MMP-9) expression in malignant and borderline ovarian tumors and its correlation to prognosis. METHODS: Forty-five patients with primary epithelial ovarian tumors were enrolled in this retrospective study from 1988 to 2002. Only malignant (n = 30) and borderline (n = 15) ovarian tumors constituted the study group. All cases were surgically staged according to FIGO criteria. Patient characteristics and clinico-pathological findings were obtained from hospital records. Paraffin-embedded tissue blocks were treated with MMP-9 immunohistochemical stain. The percentage of the total number of tumors staining positively was categorised and awarded a score of 0 to 4: < 5% as 0, < or = 6-25% as 1, 26-50% as 2, 51-75% as 3 and 76-100% as 4. The intensity of immunostaining was scored on a 3-point scale: 1, weak; 2, moderate and 3, intense. A weighed score for each tumor specimen was produced by multiplying the percentage score with the intensity score and was defined as the 'epithelial MMP-9 score'. Stromal staining was also assessed as weak, moderate and intense. Cases with final epithelial MMP-9 scores < or = 6 and > 6 were then recategorised into two groups, accordingly. Based on degree of stromal staining, cases were recategorised into two final groups as mildly stained and intense or moderately stained. Tumor stages were regrouped as early (Stage I-II) and late (Stage III-IV), respectively. RESULTS: Mean ages of cases with malignant and borderline ovarian tumors were 57.2 +/- 3.1 and 49.7 +/- 2.1 years, respectively. Epithelial MMP-9 scores were higher in malignant tumors compared to borderline tumors (p = 0.014). However, with regard to stromal MMP-9 staining, no significant difference was observed among malignant and borderline tumors (p = 0.113). Among malignant ovarian tumors, epithelial MMP-9 scores did not differ between early versus late-staged and well versus poorly differentiated tumors. Median survival time of cases with epithelial MMP-9 scores < or = 6 and > 6 were 24 months and 32 months, respectively (log-rank: 0.93, p = 0.335). Cases with weak stromal MMP-9 staining had a longer median survival (48 months) compared to cases with moderate or intense stromal MMP-9 staining (24 months, log-rank: 4.46, p = 0.03). CONCLUSION: Epithelial MMP-9 expression generally appears in the malignant form of ovarian tumors compared to borderline tumors. MMP-9 expression in the stroma but not in the epithelium contributes to poor survival in ovarian cancers.

Microvessel density as a prognostic factor in preinvasive and invasive cervical lesions.

OBJECTIVE: To assess angiogenesis in preinvasive and invasive cervical lesions and its prognostic value in squamous cell carcinoma (SCC). METHODS: Twenty-seven cervical intraepithelial lesions (CIN I, II and III), 27 Stage Ib-IIa SCC and 12 normal cervical epithelium were included in the study. Clinico-pathological prognostic factors were re-evaluated from the patients' files and previous tissue sections. Microvessel density (MVD), a marker for angiogenesis, was assessed from new tissue blocks by an immunohistochemical staining method. Statistical tests included Kruskall-Wallis analysis, the Mann-Whitney U-test, Fisher's exact t-test to analyse the categorical data and Cox regression and Kaplan-Meier survival analyses to define the effect of prognosticators on survival. RESULTS: CIN II and III lesions had significantly higher MVD counts than normal epithelium and CIN I lesions, both of which had similar MVD count. Compared to preinvasive lesions invasive SCC had significantly higher MVD counts. Among SCC cases, only pelvic lymph node involvement appeared to be independent risk factor on unvariate analysis. However, MVD, as a cut-off value of 21 determined by ROC analysis, was found to be an independent prognosticator in early stage SCC cases by multivariate analysis. CONCLUSION: Despite the small number of enrolled cases, the results of this study suggest that angiogenesis involved in the development and progression of cervical neoplasms and MVD might be used as a prognostic factor.

Preoperative serum vascular endothelial growth factor (VEGF) in ovarian masses.

PURPOSE OF THE INVESTIGATION: To determine the diagnostic value of serum vascular endothelial growth factor (VEGF) in the preoperative assessment of the nature of ovarian masses. MATERIALS AND METHODS: A prospective cohort study was conducted from August 2001 to September 2002 on 40 premenopausal and 23 postmenopausal patients with ovarian masses. During preoperative workup, patient age, serum Ca-125 levels, serum VEGF levels, and tumor volume based on ultrasonographic examination were determined. Laparoscopic (n=23) or laparotomic (n=39) approaches were undertaken to obtain the final pathologic result. According to the final ovarian pathology, follicular cysts, corpus luteum cysts and endometriomas were grouped as non-neoplastic ovarian masses (n=40, group I). Serous or mucinous cyctadenomas, dermoid tumors and fibromas were allocated into the neoplastic benign ovarian mass group (n=10, group II). Primary malignant ovarian neoplasms were categorized into the neoplastic-malign group (n=12, group III). RESULTS: Mean ages of cases among groups I, II and III were 39.0 +/- 2.0, 42.2 +/- 5.2 and 56.9 +/- 4.2, respectively. As age of the cases enrolled in this sudy increased, the more likely was the occurrence of neoplastic malign ovarian pathologies (p < 0.001). Among postmenopausal cases diagnosed with an ovarian mass, serum Ca-125 levels were 113.5 +/- 20 IU/ml compared to those in premenopausal cases (85.8 +/- 16.0, p = 0.05). The values for serum VEGF values among pre- and postmenopausal ovarian masses were 46.2 +/- 6.7 pg/ml and 68.2 +/- 7.9, respectively (p = 0.04). In group I, serum VEGF levels of endometriomas (56.5 +/- 1.5 pg/ml) were higher compared to those of follicular or corpus luteum cysts (30.6 +/- 2.8, p = 0.05). In contrast, tumor size appeared to be larger in non-endometriotic. non-neoplastic cysts (10.1 +/- 2.0 cm), compared to endometriomas (6.4 +/- 0.6 cm, p < 0.01). Serum VEGF levels of group III were higher than other groups (p < 0.001). With respect to the discriminating benign or malign nature of the mass, with a specific cut-off value of serum VEGF level of 68.7 pg/ml, the sensitivity, specificity, positive and negative likelihood ratios were 92.3%, 88.0%, 3.3 and 0.1, respectively. For serum Ca-125 levels, the sensitivity, specificity, positive and negative likelihood ratio with a statistically relevant cut-off value of 102 IU/ml were, 76.9%, 76.0%, 3.21 and 0.3, respectively. Area under curve (AUC) for serum VEGF and Ca-125 values were 0.938 (95% CI: 0.81-0.96) and 0.769 (95% CI: 0.64-0.86), respectively (p = 0.02). Among the postmenopausal group, AUC for serum VEGF and Ca-125 was detected as 0.902 (95% CI: 0.70-0.98) and 0.873 (95% CI: 0.66-0.91) (p = 0.14). CONCLUSION: Serum VEGF has the potential to be considered as a tumor marker with a good diagnostic relevance in differentiating the nature of ovarian masses.
