ABSTRACT
BACKGROUND: Prognostic value of accompanying adenomyosis in endometrial cancer is the subject of interest due to their common etiology and co-occurrence frequency. However, it is still unclear whether adenomyosis has a role in the prognosis of endometrial cancer. AIMS: The aim of this study was to determine the effects of adenomyosis on the prognosis of patients with endometrial cancer. METHODS: In this study, medical records of 552 patients with endometrioid endometrial cancer who underwent surgery between 2007 and 2017 were retrospectively reviewed. The patients were divided into two groups based on the presence or absence of adenomyosis, and these two groups were compared in terms of the clinicopathological factors and survival outcomes of patients. RESULTS: Of these patients, 103 (18.7%) had adenomyosis, and the remaining 449 (81.3%) did not. The endometrial cancer patients with adenomyosis exhibited earlier stages (p < 0.001), lower tumor grades (p < 0.001), tumor sizes ≤ 2 cm (p = 0.002), myometrial invasion < 50% (p < 0.001), and negative lymphovascular space invasion (p < 0.001). The 5-year overall survival rate was comparable between the adenomyosis and non-adenomyosis groups (95 vs. 89.1%, respectively; p = 0.085). The presence of adenomyosis was significantly associated with a higher 5-year disease-free survival rate (95.1 vs. 87.9%; p = 0.047), but adenomyosis did not remain as a prognostic factor in multivariate analysis. CONCLUSION: The results of our study showed that the endometrioid endometrial cancer patients with adenomyosis are significantly associated with smaller tumor sizes, less myometrial invasion, lower tumor grades, less lymphovascular space invasion, and earlier FIGO stages. Nevertheless, adenomyosis was not found to be an independent prognostic factor for endometrioid endometrial cancer.

INTRODUCTION: The purposes of this study were to compare adjuvant treatment modalities and to determine prognostic factors in stage III endometrioid endometrial cancer (EC). METHODS: SATEN III was a retrospective study involving 13 centers from 10 countries. Patients who had been operated on between 1998 and 2018 and diagnosed with stage III endometrioid EC were analyzed. RESULTS: A total of 990 women were identified; 317 with stage IIIA, 18 with stage IIIB, and 655 with stage IIIC diseases. The median follow-up was 42 months. The 5-year disease-free survival (DFS) of patients with stage III EC by adjuvant treatment modality was 68.5% for radiotherapy (RT), 54.6% for chemotherapy (CT), and 69.4% for chemoradiation (CRT) (p=0.11). The 5-year overall survival (OS) for those patients was 75.6% for RT, 75% for CT, and 80.7% for CRT (p=0.48). For patients with stage IIIA disease treated by RT versus CT versus CRT, the 5-year OS rates were 75.6%, 75.0%, and 80.7%, respectively (p=0.48). Negative peritoneal cytology (HR: 0.45, 95% CI: 0.23 to 0.86; p=0.02) and performance of lymphadenectomy (HR: 0.33, 95% CI: 0.16 to 0.77, p=0.001) were independent predictors for improved OS for stage IIIA EC. For women with stage IIIC EC treated by RT, CT, and CRT, the 5-year OS rates were 78.9%, 67.0%, and 69.8%, respectively (p=0.08). Independent prognostic factors for better OS for stage IIIC disease were age <60 (HR: 0.50, 95%CI: 0.36 to 0.69, p<0.001), grade 1 or 2 disease (HR: 0.59, 95% CI: 0.37 to 0.94, p=0.014; and HR: 0.65, 95%CI: 0.46 to 0.91, p=0.014, respectively), absence of cervical stromal involvement (HR: 063, 95% CI: 0.46 to 0.86, p=0.004) and performance of para-aortic lymphadenectomy (HR: 0.52, 95% CI: 0.35 to 0.72, p<0.001). DISCUSSION: Although not statistically significant, CRT seemed to be a better adjuvant treatment option for stage IIIA endometrioid EC. Systematic lymphadenectomy seemed to improve survival outcomes in stage III endometrioid EC.

PURPOSE: Side-specific systematic lymphadenectomy is suggested if sentinel lymph node (SLN) mapping failed in early stages endometrial cancer. This study aimed to evaluate the risk factors associated with failed mapping which may lead to modify SLN mapping technique, increase the success of SLN mapping and reduce the necessity of systematic lymphadenectomy. METHODS: Patients with early stage endometrial cancer were included in this study. All patients underwent SLN mapping with indocyanine green/near-infrared compatible surgical platforms. Indocyanine green was injected intracervical. "Bilateral mapping" and "failed bilateral SLN mapping (unilateral or bilateral failed mapping)" groups were compared for demographic, clinical, surgical, and pathological features. RESULTS: 101 cases were analyzed. The overall, unilateral, and bilateral SLN detection rates were 94.1%, 19.8%, and 74.3%, respectively. The failed (unilateral or no mapping) bilateral detection rate was 25.7%. Failed bilateral mapping rates were higher in patients with longer cervical and uterine longitudinal lengths, deep myometrial invasion and larger tumor size without statistical significance. Body mass index and operation type were not related with failed mapping. Increasing number of operations or injection of larger volume of indocyanine green (4 mL vs. 2 mL) did not improve mapping rate significantly. CONCLUSION: Cervical indocyanine green injection may overcome the negative effect of obesity on bilateral mapping. Although there was a negative correlation trend between the longitudinal cervical and uterine lengths and bilateral mapping, this possible relation needs to be confirmed in further studies.

OBJECTIVE: The purpose of this study was to assess the prognostic significance of lymphovascular space invasion in women with low-risk endometrial cancer. METHODS: A dual-institutional, retrospective department database review was performed to identify patients with 'low-risk endometrial cancer' (patients having <50% myometrial invasion with grade 1 or 2 endometrioid endometrial cancer according to their final pathology reports) at two gynecologic oncology centers in Ankara, Turkey. Demographic, clinicopathological and survival data were collected. RESULTS: We identified 912 women with low-risk endometrial cancer; 53 patients (5.8%) had lymphovascular space invasion. When compared with lymphovascular space invasion-negative patients, lymphovascular space invasion-positive patients were more likely to have post-operative grade 2 disease (p<0.001), deeper myometrial invasion (p=0.003), and larger tumor size (p=0.005). Patients with lymphovascular space invasion were more likely to receive adjuvant therapy when compared with lymphovascular space invasion-negative women (11/53 vs 12/859, respectively; p<0.001). The 5-year recurrence-free survival rate for lymphovascular space invasion-positive women was 85.5% compared with 97.0% for lymphovascular space invasion-negative women (p<0.001). The 5-year overall survival rate for lymphovascular space invasion-positive women was significantly lower than that of lymphovascular space invasion-negative women (88.2% vs 98.5%, respectively; p<0.001). Age ≥60 years (HR 3.13, 95% CI 1.13 to 8.63; p=0.02) and positive lymphovascular space invasion status (HR 6.68, 95% CI 1.60 to 27.88; p=0.009) were identified as independent prognostic factors for decreased overall survival. CONCLUSIONS: Age ≥60 years and positive lymphovascular space invasion status appear to be important prognostic parameters in patients with low-risk endometrial cancer who have undergone complete surgical staging procedures including pelvic and para-aortic lymphadenectomy. Lymphovascular space invasion seems to be associated with an adverse prognosis in women with low-risk endometrial cancer; this merits further assessment on a larger scale with standardization of the lymphovascular space invasion in terms of presence/absence and quantity.

OBJECTIVE: The purpose of this study was to determine the patterns of failure and prognostic factors for lymphovascular space invasion (LVSI)-positive endometrioid endometrial cancer (EC) patients in the setting of negative lymph nodes (LNs). MATERIALS AND METHODS: A multicenter, retrospective department database review was performed to identify LVSI-positive patients with disease surgically confined to the uterus at two gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. RESULTS: We identified 185 LVSI-positivewomen with negative LNs during the study period. Fifty-five (29.7%) were classified as Stage IA, 94 (50.8%) as Stage IB, and 36 (19.5%) as Stage II. The median age at diagnosis was 59 years and the median duration of follow-up was 44 months. The total number of the recurrences was 12 (6.5%). We observed 5 (2.9%) loco-regional recurrences, 3 (1.5%) retroperitoneal failures, and 4 (2.0%) distant relapses. The 5-year progression-free survival (PFS) was 86.1% while the 5-year overall survival (OS) rate was 87.7%. Grade 3 histology (Hazard Ratio [HR] 2.9, 95% Confidence Interval [CI] 1.02-8.50; p = 0.04), cervical stromal invasion (HR 4.5, 95% CI 1.61-12.79; p = 0.004) and age ≥ 60 years (HR 5.8, 95% CI 1.62-21.32; p = 0.007) were found to be independent prognostic factors for decreased OS. Adjuvant treatment did not appear as a prognostic factor for OS even in univariate analysis. CONCLUSION: The recurrence rate among LVSI-positive endometrioid EC patients is low in the setting of negative LNs. However, one out of three patients with a recurrence experiences distant relapses which usually portend worse outcomes.

BACKGROUND: The purpose of this case-control study was to compare the prognoses of women with stage III mucinous ovarian carcinoma (MOC) who received maximal or optimal cytoreduction followed by paclitaxel plus carboplatin chemotherapy to those of women with stage III serous epithelial ovarian cancer (EOC) treated in the similar manner. METHODS: We performed a multicenter, retrospective review to identify patients with stage III MOC at seven gynecologic oncology departments in Turkey. Eighty-one women with MOC were included. Each case was matched to two women with stage III serous EOC in terms of age, tumor grade, substage of disease, and extent of residual disease. Survival estimates were measured using Kaplan-Meier plots. Variables predictive of outcome were analyzed using Cox regression models. RESULTS: With a median follow-up of 54 months, the median progression-free survival (PFS) for women with stage III MOC was 18.0 months (95% CI; 13.8-22.1, SE: 2.13) compared to 29.0 months (95% CI; 24.04-33.95, SE: 2.52) in the serous group (p = 0.19). The 5-year overall survival rate of the MOC group was significantly lower than that of the serous EOC group (44.9% vs. 66.3%, respectively; p < 0.001). For the entire cohort, presence of multiple peritoneal implants (Hazard ratio [HR] 2.39; 95% confidence interval [CI], 1.38-4.14, p = 0.002) and mucinous histology (HR 2.28; 95% CI, 1.53-3.40, p < 0.001) were identified as independent predictors of decreased OS. CONCLUSION: Patients with MOC seem to be 2.3 times more likely to die of their tumors when compared to women with serous EOC.

INTRODUCTION: We aimed to assess risk factors for lymph node (LN) metastasis among lymphovascular space invasion(LVSI)-positive women with pure endometrioid endometrial cancer (EC) clinically confined to the uterus. METHODS: Medical records of women who underwent primary surgery for EC between 2007 and 2016 at either of 2 gynecological oncology centers were retrospectively reviewed. Patient data were analyzed with respect to LN involvement, and predictive factors for LN metastasis were investigated. RESULTS: 280 patients with surgically staged endometrioid-type EC with LVSI were identified. LN involvement was detected in 88 patients (31.4%) with a systematic LN dissection. In multivariate analysis, elevated baseline serum CA 125 levels, deep myometrial invasion (MMI), adnexal involvement and positive peritoneal cytology were found to be independent risk factors for LN metastasis. In women without deep MMI and elevated baseline serum CA 125 levels, the rate of LN metastasis was 19%. The presence of solely deep MMI increased this probability up to 29.1%. The rate of LN metastasis was found to be 46.8% for women with both deep MMI and elevated baseline serum CA 125 levels. CONCLUSION: These findings may be useful in the decision-making process for LVSI-positive women who are unstaged.

BACKGROUND: The purpose of this retrospective study was to determine the prognosis of non-serous epithelial ovarian cancer (EOC) patients with exclusively retroperitoneal lymph node (LN) metastases, and to compare the prognosis of these women to that of patients who had abdominal peritoneal involvement. METHODS: A multicenter, retrospective department database review was performed to identify patients with stage III non-serous EOC at 7 gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. The patients were divided into three groups based on the initial sites of disease: 1) the retroperitoneal (RP) group included patients who had positive pelvic and /or para-aortic LNs only. 2) The intraperitoneal (IP) group included patients with > 2 cm IP dissemination outside of the pelvis. These patients all had a negative LN status, 3) The IP / RP group included patients with > 2 cm IP dissemination outside of the pelvis as well as positive LN status. Survival data were compared with regard to the groups. RESULTS: We identified 179 women with stage III non-serous EOC who were treated at 7 participating centers during the study period. The median age of the patients was 53 years, and the median duration of follow-up was 39 months. There were 35 (19.6%) patients in the RP group, 72 (40.2%) in the IP group and 72 (40.2%) in the IP/RP group. The 5-year disease-free survival (DFS) rates for the RP, the IP, and IP/RP groups were 66.4%, 37.6%, and 25.5%, respectively (p = 0.002). The 5-year overall survival (OS) rate for the RP group was significantly longer when compared to those of the IP, and the IP/RP groups (74.4% vs. 54%, and 36%, respectively; p = 0.011). However, we were not able to define "RP only disease" as an independent prognostic factor for increased DFS or OS. CONCLUSIONS: Primary non-serous EOC patients with node-positive-only disease seem to have better survival when compared to those with extra-pelvic peritoneal involvement.

BACKGROUND: The purpose of this study was to compare the prognoses of women with pure ovarian clear cell carcinoma (OCCC) arising from endometriosis to those of women with pure OCCC not arising from endometriosis treated in the same manner. METHODS: A dual-institutional, retrospective database review was performed to identify patients with pure OCCC who were treated with maximal or optimal cytoreductive surgery (CRS) followed by paclitaxel/carboplatin chemotherapy between January 2006 and December 2016. Patients were divided into two groups according to the detection of cancer arising in endometriosis or not, on the basis of pathological findings. Demographic, clinicopathological, and survival data were collected, and prognosis was compared between the two groups. RESULTS: Ninety-three women who met the inclusion criteria were included. Of these patients, 48 (51.6%) were diagnosed with OCCC arising in endometriosis, while 45 (48.4%) had no concomitant endometriosis. OCCC arising in endometriosis was found more frequently in younger women and had a higher incidence of early stage disease when compared to OCCC patients without endometriosis. The 5-year overall survival (OS) rate of the patients with OCCC arising in endometriosis was found to be significantly longer than that of women who had OCCC without endometriosis (74.1 vs. 46.4%; p = 0.003). Although univariate analysis revealed the absence of endometriosis (p = 0.003) as a prognostic factor for decreased OS, the extent of CRS was identified as an independent prognostic factor for both recurrence-free survival (hazard ratio (HR) 8.7, 95% confidence interval (CI) 3.15-24.38; p < 0.001) and OS (HR 11.7, 95% CI 3.68-33.71; p < 0.001) on multivariate analysis. CONCLUSION: Our results suggest that endometriosis per se does not seem to affect the prognosis of pure OCCC.

OBJECTIVE: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in patients with stage III ovarian high-grade serous carcinoma (HGSC). METHODS: A multicenter, retrospective department database review was performed to identify patients with ovarian HGSC at 6 gynecologic oncology centers in Turkey. A total of 229 node-positive women with stage III ovarian HGSC who had undergone maximal or optimal cytoreductive surgery plus systematic lymphadenectomy followed by paclitaxel plus carboplatin combination chemotherapy were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 3 groups: LNR1 (<10%), LNR2 (10%≤LNR<50%), and LNR3 (≥50%). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. RESULTS: Thirty-one women (13.6%) were classified as stage IIIA1, 15 (6.6%) as stage IIIB, and 183 (79.9%) as stage IIIC. The median age at diagnosis was 56 (range, 18-87), and the median duration of follow-up was 36 months (range, 1-120 months). For the entire cohort, the 5-year overall survival (OS) was 52.8%. An increased LNR was associated with a decrease in 5-year OS from 65.1% for LNR1, 42.5% for LNR2, and 25.6% for LNR3, respectively (p<0.001). In multivariate analysis, women with LNR≥0.50 were 2.7 times more likely to die of their tumors (hazard ratio [HR]=2.7; 95% confidence interval [CI]=1.42-5.18; p<0.001). CONCLUSION: LNR seems to be an independent prognostic factor for decreased OS in stage III ovarian HGSC patients.

OBJECTIVE: The purpose of this retrospective study was to compare the prognoses of women with ovarian carcinosarcoma (OCS) who had optimal cytoreductive surgery followed by platinum plus taxane combination chemotherapy to those of women with ovarian high-grade serous carcinoma (HGSC) treated in the same manner. METHODS: A multicenter, retrospective department database review was performed to identify patients with OCS at eight gynecologic oncology centers in Turkey. A total of 54 women with OCS who had undergone optimal cytoreductive surgery followed by platinum plus taxane combination chemotherapy between 1999 and 2017 were included in this case-control study. Each case was matched to two women with ovarian HGSC who had undergone optimal cytoreductive surgery followed by platinum plus taxane combination chemotherapy. The Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analysed using Cox proportional hazards models. RESULTS: Median disease-free survival (DFS) was 29 months [95% confidence interval (CI) 0-59, standard error (SE) 15.35] versus 27 months (95% CI 22.6-31.3, SE 2.22; p = 0.765) and median overall survival (OS) was 62 versus 82 months (p = 0.53) for cases and controls, respectively. For the entire cohort, the presence of ascites [hazard ratio (HR) 2.32; 95% CI 1.02-5.25, p = 0.04] and platinum resistance [HR 5.05; 95% CI 2.32-11, p < 0.001] were found to be independent risk factors for decreased OS. CONCLUSION: DFS and OS rates of patients with OCS and HGSC seem to be similar whenever optimal cytoreduction is achieved and followed by platinum plus taxane combination chemotherapy.

OBJECTIVE: To compare the clinical validity of the Gynecologic Oncology Group-99 (GOG-99), the Mayo-modified and the European Society for Medical Oncology (ESMO)-modified criteria for predicting lymph node (LN) involvement in women with endometrioid endometrial cancer (EC) clinically confined to the uterus. METHODS: A total of 625 consecutive women who underwent comprehensive surgical staging for endometrioid EC clinically confined to the uterus were divided into low- and high-risk groups according to the GOG-99, the Mayo-modified, and the ESMO-modified criteria. Lymphovascular space invasion is the cornerstone of risk stratification according to the ESMO-modified criteria. These 3 risk stratification models were compared in terms of predicting LN positivity. RESULTS: Systematic LN dissection was achieved in all patients included in the study. LN involvement was detected in 70 (11.2%) patients. LN involvement was correctly estimated in 51 of 70 LN-positive patients according to the GOG-99 criteria (positive likelihood ratio [LR+], 3.3; negative likelihood ratio [LR-], 0.4), 64 of 70 LN-positive patients according to the ESMO-modified criteria (LR+, 2.5; LR-, 0.13) and 69 of the 70 LN-positive patients according to the Mayo-modified criteria (LR+, 2.2; LR-, 0.03). The area under curve of the Mayo-modified, the GOG-99 and the ESMO-modified criteria was 0.763, 0.753, and 0.780, respectively. CONCLUSION: The ESMO-modified classification seems to be the risk-stratification model that most accurately predicts LN involvement in endometrioid EC clinically confined to the uterus. However, the Mayo-modified classification may be an alternative model to achieve a precise balance between the desire to prevent over-treatment and the ability to diagnose LN involvement.

OBJECTIVE: Lymphangiomas are rare benign tumors which are generally seen in pediatric population and the etiopathogenesis has not yet been understood. They occasionally occur in the head and neck or axillary region with only 5% of them being located in the abdominal or mediastinal cavity. These tumors may be asymptomatic or may cause acute abdominal symptoms due to the location and extention. In the English literature, only 4 cases of lymphangioma were reported to have occurred in the pregnancy period. Herein, we report a case of cystic lymphangioma of the lesser omentum detected incidentally on the ultrasonogram of a 21 year-old, 26-week pregnant woman. The patient was followed up uneventfully during pregnancy. Caesarean section was performed due to transverse presentation of the fetus, and the tumor was completely resected during the same session. The patient is recurrence-free after 1 year of postoperative follow-up.

OBJECTIVE: Primary tumors of round ligament are rare, and when found are typically leiomyomas. Endometrioma, and mesothelial cysts are the benign lesions recognized as involving the round ligament. We report a case of lipoma of the round ligament in a 48-year-old premenopausal woman. Round ligament lipoma on the intraperitoneal portion (abdominal site) is very rare and it should be kept in the differential diagnosis of ovarian and abdominal masses.

OBJECTIVES: Selection of patients with endometrioid endometrial cancer (EEC), in whom systematic lymph node dissection (LND) is indicated, is an important part of management to maintain optimal oncological outcomes, while avoiding unnecessary morbidities. According to the current approach, LND is recommended for the patients with International Federation of Gynecology and Obstetrics (FIGO) grade 1 to 2 tumors and a primary tumor diameter (PTD) greater than 2 cm, even with myometrial invasion (MMI) of less than 50%. We aimed to determine incidence of LN metastasis in this particular group of patients with grade 1 tumors, superficial MMI, and a PTD greater than 2 cm. MATERIALS AND METHODS: This study only focused on women with FIGO grade 1 EEC having less than 50% MMI. Therefore, women with grade 2 or 3 tumors were excluded, as well as patients with 50% or greater MMI. We also excluded women with macroscopic extrauterine disease, as well as patients with cervical stromal involvement. Patients were divided into subgroups with regard to PTD; group 1 was composed of patients with PTD of 20 mm or less, whereas group 2 was composed of patients with PTD greater than 20 mm. All clinical and pathological variables were compared between the groups. RESULTS: Final pathology reports of 484 women with EEC who underwent surgical staging were analyzed. Among these women, there were 123 women in group 1 (PTD ≤ 20 mm) and 120 women in group 2 (PTD > 20 mm), with FIGO grade 1 tumors and superficial MMI. The median number of total LNs removed was 54 (range, 20-151). There were no women with pelvic and/or para-aortic LN metastasis in group 2, as well as in group 1. CONCLUSIONS: Our results suggest that lymphadenectomy may be omitted in women with FIGO grade 1 EEC having superficial MMI regardless of PTD. Deferral of systematic LND in this subgroup of patients may lead to reductions in costs and surgical morbidity.

OBJECTIVE: To determine factors influencing overall survival following recurrence (OSFR) in women with low-risk endometrial cancer (EC) treated with surgery alone. METHODS: A multicenter, retrospective department database review was performed to identify patients with recurrent "low-risk EC" (patients having less than 50% myometrial invasion [MMI] with grade 1 or 2 endometrioid EC) at 10 gynecologic oncology centers in Turkey. Demographic, clinicopathological, and survival data were collected. RESULTS: We identified 67 patients who developed recurrence of their EC after initially being diagnosed and treated for low-risk EC. For the entire study cohort, the median time to recurrence (TTR) was 23 months (95% confidence interval [CI]=11.5-34.5; standard error [SE]=5.8) and the median OSFR was 59 months (95% CI=12.7-105.2; SE=23.5). We observed 32 (47.8%) isolated vaginal recurrences, 6 (9%) nodal failures, 19 (28.4%) peritoneal failures, and 10 (14.9%) hematogenous disseminations. Overall, 45 relapses (67.2%) were loco-regional whereas 22 (32.8%) were extrapelvic. According to the Gynecologic Oncology Group (GOG) Trial-99, 7 (10.4%) out of 67 women with recurrent low-risk EC were qualified as high-intermediate risk (HIR). The 5-year OSFR rate was significantly higher for patients with TTR ≥36 months compared to those with TTR <36 months (74.3% compared to 33%, p=0.001). On multivariate analysis for OSFR, TTR <36 months (hazard ratio [HR]=8.46; 95% CI=1.65-43.36; p=0.010) and presence of HIR criteria (HR=4.62; 95% CI=1.69-12.58; p=0.003) were significant predictors. CONCLUSION: Low-risk EC patients recurring earlier than 36 months and those carrying HIR criteria seem more likely to succumb to their tumors after recurrence.

OBJECTIVE: To assess the prognosis of surgically-staged non-invasive uterine clear cell carcinoma (UCCC), and to determine the role of adjuvant therapy. METHODS: A multicenter, retrospective department database review was performed to identify patients with UCCC who underwent surgical treatment between 1997 and 2016 at 8 Gynecologic Oncology Centers. Demographic, clinicopathological, and survival data were collected. RESULTS: A total of 232 women with UCCC were identified. Of these, 53 (22.8%) had surgically-staged non-invasive UCCC. Twelve patients (22.6%) were upstaged at surgical assessment, including a 5.6% rate of lymphatic dissemination (3/53). Of those, 1 had stage IIIA, 1 had stage IIIC1, 1 had stage IIIC2, and 9 had stage IVB disease. Of the 9 women with stage IVB disease, 5 had isolated omental involvement indicating omentum as the most common metastatic site. UCCC limited only to the endometrium with no extra-uterine disease was confirmed in 41 women (73.3%) after surgical staging. Of those, 13 women (32%) were observed without adjuvant treatment whereas 28 patients (68%) underwent adjuvant therapy. The 5-year disease-free survival rates for patients with and without adjuvant treatment were 100.0% vs. 74.1%, respectively (p=0.060). CONCLUSION: Extra-uterine disease may occur in the absence of myometrial invasion (MMI), therefore comprehensive surgical staging including omentectomy should be the standard of care for women with UCCC regardless of the depth of MMI. Larger cohorts are needed in order to clarify the necessity of adjuvant treatment for women with UCCC truly confined to the endometrium.

OBJECTIVE: The purpose of this study was to determine the risk factors for paraaortic lymph node (LN) metastasis in endometrial cancer (EC) patients who underwent comprehensive surgical staging. METHODS: A total of 641 women with EC (endometrioid, non-endometrioid, or mixed histology) who underwent comprehensive surgical staging including pelvic and paraaortic LN dissection between 2008 and 2016 were included in this retrospective study. Patient data were analyzed with respect to paraaortic LN involvement, and predictive factors for paraaortic LN metastasis were investigated. RESULTS: Lymph node metastasis was detected in 90 (14%) patients, isolated pelvic LN metastasis in 28 (4.3%), isolated paraaortic LN metastasis in 15 (2.3%), and both pelvic and paraaortic LN metastasis in 47 (7.3%) women, respectively. Univariate analysis showed that the risk of paraaortic LN metastasis significantly increased in patients with non-endometrioid histology, age greater than 60 years, grade 3 tumor, deep myometrial invasion, lymphovascular space invasion (LVSI), primary tumor diameter (≥2 cm), cervical stromal invasion, adnexal involvement, serosal invasion, pelvic LN involvement, two or more positive pelvic LNs, and positive peritoneal cytology (p < 0.05). At the end of multivariate analysis, the presence of LVSI [odds ratio (OR), 4.8; 95% confidence interval (CI), 1.25-18.2; p = 0.022] and pelvic LN metastasis (OR, 18.8; 95% CI, 5.7-61.6; p < 0.001) remained as independent risk factors for paraaortic LN involvement in women with EC. CONCLUSION: The presence of LVSI and pelvic LN involvement appear to be independent risk factors for paraaortic LN metastasis in patients with EC. LVSI may be considered as a routine pathological parameter during frozen section analysis in women with EC undergoing surgery.

OBJECTIVE: To evaluate the risk factors for appendiceal involvement in women with epithelial ovarian cancer (EOC) who underwent appendectomy at the time of initial surgery. MATERIAL AND METHODS: Patients with a final diagnosis of EOC who underwent appendectomy at the time of initial surgery were evaluated retrospectively. Risk factors related to the presence of appendiceal involvement were analyzed. RESULTS: A total of 210 patients underwent appendectomy during staging surgery. Appendiceal involvement was detected in 61 patients. No women with apparent clinical early-stage tumors had evidence of isolated metastatic disease to the appendix; therefore, no upstaging was detected due to solitary appendiceal involvement in this group of patients. For all patients, univariate analysis of the appendiceal involvement revealed age, stage, grade, extragenital organ involvement (omentum, bowel, peritoneum), positive cytology, and lymph node metastasis as significant factors (p<0.05). In the multivariate analysis, appendiceal involvement was significantly affected by age and omental involvement. Older age (>50 years) [odds ratio (OR) 2.8; 95% confidence interval (CI): (1.24-6.37); p=0.014] and presence of omental involvement [OR: 3.2; 95% CI: (1.22-8.59); p=0.018) seemed to be independent risk factors for appendiceal involvement in women with EOC. CONCLUSION: Our findings indicate that routine appendectomy at the time of surgery for apparent early-stage EOC is not warranted. Nevertheless, the surgeon can take the initiative in regards to performing appendectomy because the morbidity rates due to this procedure are negligible. Older age (>50 years) and presence of omental involvement seem to increase the risk of appendiceal involvement by 2.8 and 3.2 times, respectively.
ABSTRACT
OBJECTIVES: Primary ovarian fibrosarcomas are extremely rare neoplasms, and only 50 cases have been reported in the English literature. Diagnosis can be difficult because of this condition's rarity, and other similar appearing mesenchymal lesions should be ruled out. METHODS: A 50-year-old postmenopausal woman came to our hospital because of abdominopelvic pain. Ultrasonography revealed a 41x33 mm heterogeneous solid mass in the right ovary. Total blood counts, biochemical parameters, and tumor markers were within normal ranges. Total abdominal hysterectomy, and bilateral salpingo oophorectomy were performed. Examination of a frozen, specimen revealed fibroma; however, the final histopathological diagnosis was low grade fibrosarcoma of the ovary. Microscopic examination demonstrated densely cellular, spindle-shaped tumor cells with increased mitotic activity (5 to 6 mitoses per 10 high-power fields). RESULTS: Immunohistochemical analysis revealed that the tumor cells were positive for vimentin and negative for actin and desmin and that the Ki 67 proliferation index was 30% to 40%. The patient did not receive adjuvant treatment, and remained free of disease after a follow up of 6 months. CONCLUSIONS: Although ovarian fibrosarcomas are unusual causes of solid masses in postmenopausal women, they should be considered when adnexal masses are examined in these patients. Mitotic activity and Ki-67 positivity were identified as important diagnostic factors for ovarian fibrosarcoma.
