The Relationship Between Melatonin 1-2 Receptor Expression in Patients With Epithelial Ovarian Cancer and Survival.

Melatonin has antiproliferative, antiangiogenic, apoptotic, and immunomodulatory properties in ovarian cancer. Considering those, we evaluated the relationship between melatonin 1 (MT1) and melatonin 2 receptor (MT2) expression in tumor tissues of patients with epithelial ovarian cancer, disease-free survival (DFS), and overall survival (OS). Patients who received primary surgical treatment for epithelial ovarian cancer in our clinic between 2000 and 2019 were retrospectively scanned through patient files, electronic databases, and telephone calls. One hundred forty-two eligible patients were included in the study, their tumoral tissues were examined to determine MT1 and MT2 expression by immunohistochemical methods. The percentage of receptor-positive cells and intensity of staining were determined. MT1 receptor expression ( P = 0.002 for DFS and P = 0.002 for OS) showed a significant effect on DFS and OS. MT2 expression had no effect on survival ( P = 0.593 for DFS and P = 0.209 for OS). The results showed that the higher the MT1 receptor expression, the longer the DFS and OS. It is suggested that melatonin should be considered as adjuvant therapy for ovarian cancer patients in addition to standard treatment, and clinical progress should be observed.

3-4 Cycles vs 6 Cycles NACT in Advanced Stage Epithelial Ovarian Cancer: Survival is not Determined by the Number of NACT Cycles.

INTRODUCTION: The aim of this study was to compare the disease-free survival (DFS) and overall survival (OS) of patients who underwent interval cytoreductive surgery after 3-4 cycles or 6 cycles of neoadjuvant chemotherapy (NACT) in advanced epithelial ovarian cancer patients. METHODS: Out of 219 patients with advanced epithelial ovarian cancer,123 patients received 3-4 cycles and 96 patients received 6 cycles of platinum-based NACT. Afterwards, laparotomy was performed for interval cytoreductive surgery. RESULTS: No statistically significant difference was found for DFS and OS of the patients who received 3-4 cycles and those who received 6 cycles of NACT (HR:1.047,95.0%CI [0.779-1.407]; p:0.746 for DFS, and HR:1.181,95.0% CI [0.818-1.707]; p:0.368 for OS). Evaluating 123 patients who received 3-4 cycles of NACT;87 patients (70.7%) without macroscopic residual tumor after interval cytoreductive surgery had significantly longer DFS and OS compared to 36 patients(29.3%) with any residual tumor (HR:1.830,95.0% CI [1.194-2.806]; p:0.003 for DFS, and HR:1.946,95.0% CI [1.166-3.250]; p:0.009 for OS).96 patients who received 6 courses of NACT were evaluated;63 patients (65.6%) without macroscopic residual tumor after interval cytoreductive surgery had significantly longer DFS and OS than 33 patients (34.4%) with any residual tumor (HR:1.716,95.0% CI [1.092-2.697];p:0.010 for DFS, and HR:1.921,95.0%CI [1.125-3.282]; p:0.013 for OS). CONCLUSION: In patients with advanced ovarian cancer,there is no significant difference in DFS and OS between 3-4 cycles or 6 cycles of NACT.The most important factor determining survival is whether macroscopic residual tumor tissue remains after interval cytoreductive surgery following NACT.

The relationship between tumor mean standard uptake value (SUVmax) in preoperative PET/computed tomography and prognostic risk groups in endometrial cancer.

OBJECTIVE: Our aim in this study was to determine the relationship between tumor mean standard uptake value (SUVmax) value in preoperative PET/computed tomography (CT) and prognostic risk groups in cases with endometrial cancer. METHODS: A total of 368 patients operated on for endometrial cancer were evaluated in the study. The SUVmax value of endometrial primary tumor of the patients screened within 30 days of operation, was compared with prognostic parameters and risk groups. P value <0.05 was considered significant for all tests. RESULTS: A statistically significant relationship was found between the mean SUVmax value and risk groups ( P < 0.001), grade ( P < 0.001), stage ( P < 0.001), myometrial invasion of the tumor ( P < 0.001), cervical involvement ( P = 0.002), lymphovascular space invasion (LVSI) ( P < 0.001), lymph node metastasis ( P < 0.001), tumor size ( P < 0.001), lymph node involvement in PET/CT ( P < 0.001). There was no significant relationship found between the histologic type of tumor and the mean SUVmax value ( P = 0.113). Cutoff SUVmax value for endometrial cancer tumor tissue, which will be used to determine the possible lymph node metastasis, was accepted as 19 as a result of the ROC analysis. The risk of lymph node metastasis was found 4.74 times (confidence interval, 2.510-8.977) higher in patients with SUVmax value above cutoff 19 ( P < 0.001). Considering risk groups, it was observed that patients with mean SUVmax value above 19 were in intermediate-high and high risk group, 2.3 times more than those in low and intermediate risk group ( P < 0.001). As a result of logistic regression analysis, in determining intermediate-high and high-risk groups, histological type ( P < 0.001), myometrial invasion ( P = 0.003), cervical invasion (CI) ( P < 0.001), grade ( P = 0.018) and SUVmax value ( P = 0.028) had statistically significant importance. CONCLUSION: The higher the mean SUVmax value in the endometrial cancer tumor tissue in preoperative PET/CT in patients with endometrial cancer, the higher the risk group of the patients.

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer.

OBJECTIVE: To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer. METHODS: In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers. We constructed a weighted cohort using inverse probability weighting to adjust for the variables. We compared disease-free survival and overall survival using Cox proportional hazards regression analysis in the weighted cohort. RESULTS: A total of 838 patients were included in the study. The mean number of quality indicators compliance in this cohort was 13.6 (SD 1.45). A total of 479 (57.2%) patients were operated on at high compliance centers and 359 (42.8%) patients at low compliance centers. High compliance centers performed more open surgeries (58.4% vs 36.7%, p<0.01). Women who were operated on at centers with high compliance with quality indicators had a significantly lower risk of relapse (HR=0.39; 95% CI 0.25 to 0.61; p<0.001). The association was reduced, but remained significant, after further adjustment for conization, surgical approach, and use of manipulator surgery (HR=0.48; 95% CI 0.30 to 0.75; p=0.001) and adjustment for adjuvant therapy (HR=0.47; 95% CI 0.30 to 0.74; p=0.001). Risk of death from disease was significantly lower in women operated on at centers with high adherence to quality indicators (HR=0.43; 95% CI 0.19 to 0.97; p=0.041). However, the association was not significant after adjustment for conization, surgical approach, use of manipulator surgery, and adjuvant therapy. CONCLUSIONS: Patients with early cervical cancer who underwent radical hysterectomy in centers with high compliance with ESGO quality indicators had a lower risk of recurrence and death.

A Randomized, Phase III Trial to Evaluate Rucaparib Monotherapy as Maintenance Treatment in Patients With Newly Diagnosed Ovarian Cancer (ATHENA-MONO/GOG-3020/ENGOT-ov45).

PURPOSE: ATHENA (ClinicalTrials.gov identifier: NCT03522246) was designed to evaluate rucaparib first-line maintenance treatment in a broad patient population, including those without BRCA1 or BRCA2 (BRCA) mutations or other evidence of homologous recombination deficiency (HRD), or high-risk clinical characteristics such as residual disease. We report the results from the ATHENA-MONO comparison of rucaparib versus placebo. METHODS: Patients with stage III-IV high-grade ovarian cancer undergoing surgical cytoreduction (R0/complete resection permitted) and responding to first-line platinum-doublet chemotherapy were randomly assigned 4:1 to oral rucaparib 600 mg twice a day or placebo. Stratification factors were HRD test status, residual disease after chemotherapy, and timing of surgery. The primary end point of investigator-assessed progression-free survival was assessed in a step-down procedure, first in the HRD population (BRCA-mutant or BRCA wild-type/loss of heterozygosity high tumor), and then in the intent-to-treat population. RESULTS: As of March 23, 2022 (data cutoff), 427 and 111 patients were randomly assigned to rucaparib or placebo, respectively (HRD population: 185 v 49). Median progression-free survival (95% CI) was 28.7 months (23.0 to not reached) with rucaparib versus 11.3 months (9.1 to 22.1) with placebo in the HRD population (log-rank P = .0004; hazard ratio [HR], 0.47; 95% CI, 0.31 to 0.72); 20.2 months (15.2 to 24.7) versus 9.2 months (8.3 to 12.2) in the intent-to-treat population (log-rank P < .0001; HR, 0.52; 95% CI, 0.40 to 0.68); and 12.1 months (11.1 to 17.7) versus 9.1 months (4.0 to 12.2) in the HRD-negative population (HR, 0.65; 95% CI, 0.45 to 0.95). The most common grade ≥ 3 treatment-emergent adverse events were anemia (rucaparib, 28.7% v placebo, 0%) and neutropenia (14.6% v 0.9%). CONCLUSION: Rucaparib monotherapy is effective as first-line maintenance, conferring significant benefit versus placebo in patients with advanced ovarian cancer with and without HRD.

Diagnostic and prognostic role of TFF3, Romo-1, NF-кB and SFRP4 as biomarkers for endometrial and ovarian cancers: a prospective observational translational study.

PURPOSE: This study aimed to evaluate trefoil factor 3 (TFF3), secreted frizzled-related protein 4 (sFRP4), reactive oxygen species modulator 1 (Romo1) and nuclear factor kappa B (NF-κB) as diagnostic and prognostic markers of endometrial cancer (EC) and ovarian cancer (OC). METHODS: Thirty-one patients with EC and 30 patients with OC undergone surgical treatment were enrolled together with 30 healthy controls in a prospective study. Commercial ELISA kits determined serum TFF-3, Romo-1, NF-кB and sFRP-4 concentrations. RESULTS: Serum TFF-3, Romo-1 and NF-кB levels were significantly higher in patients with EC and OC than those without cancer. Regarding EC, none of the serum biomarkers differs significantly between endometrial and non-endometrioid endometrial carcinomas. Mean serum TFF-3 and NF-кB levels were significantly higher in advanced stages. Increased serum levels of TFF-3 and NF-кB were found in those with a higher grade of the disease. Regarding OC, none of the serum biomarkers differed significantly among histological subtypes. Significantly increased serum levels of NF-кB were observed in patients with advanced-stage OC than those with stage I and II diseases. No difference in serum biomarker levels was found between those who had a recurrence and those who had not. The sensibility and specificity of these four biomarkers in discriminating EC and OC from the control group showed encouraging values, although no one reached 70%. CONCLUSIONS: TFF-3, Romo-1, NF-кB and SFRP4 could represent new diagnostic and prognostic markers for OC and EC. Further studies are needed to validate our results.

Diagnostic accuracy of sentinel node biopsy in non-endometrioid, high-grade and/or deep myoinvasive endometrial cancer: A Turkish gynecologic oncology group study (TRSGO-SLN-006).

INTRODUCTION: This study aimed to evaluate the diagnostic accuracy of the sentinel lymph node (SLN) mapping algorithm in high-risk endometrial cancer patients. METHODS: Two hundred forty-four patients with non-endometrioid histology, grade 3 endometrioid tumors and/or tumors with deep myometrial invasion were enrolled in this retrospective, multicentric study. After removal of SLNs, all patients underwent pelvic ± paraaortic lymphadenectomy. Operations were performed via laparotomy, laparoscopy or robotic surgery. Indocyanine green (ICG) and methylene blue (MB) were used as tracers. SLN detection rate, sensitivity, negative predictive value (NPV) and false-negative rate (FNR) were calculated. RESULTS: Surgeries were performed via laparotomy in 132 (54.1%) patients and 152 (62.3%) underwent both bilateral pelvic and paraaortic lymphadenectomy. At least 1 SLN was detected in 222 (91%) patients. Fifty-five (22.5%) patients had lymphatic metastasis and 45 patients had at least 1 metastatic SLN. Lymphatic metastases were detected by side-specific lymphadenectomy in 8 patients and 2 patients had isolated paraaortic metastasis. Overall sensitivity, NPV and FNR of SLN biopsy were 81.8%, 95% and 18.2%, respectively. By applying SLN algorithm steps, sensitivity and NPV improved to 96.4% and 98.9%, respectively. For grade 3 tumors, sensitivity, NPV and FNR of the SLN algorithm were 97.1%, 98.9% and 2.9%. CONCLUSION: SLN algorithm had high diagnostic accuracy in high-risk endometrial cancer. All pelvic metastases were detected by the SLN algorithm and the isolated paraaortic metastasis rate was ignorable. But long-term survival studies are necessary before this approach becomes standard of care.

Juvenile granulosa cell tumor: 20 years' experience of a Tertiary Center.

OBJECTIVES: The aim of this study is to share of the 20-year experience of a tertiary center about juvenile granulosa cell tumor (JGCT) and describe clinic manifestations, treatment, and outcome of patients who diagnosed JGCT. MATERIAL AND METHODS: Five patients who diagnosed juvenile granulosa cell tumor between 2000 and 2020 were included in the study. The demographics, clinical findings and outcomes were retrospectively evaluated. Of the 5 patients in our study, one was in the premenarcheal girl. The common complaint in all of our patients was abdominal swelling. In preoperative imaging methods, all patients had unilateral adnexal mass and no signs in favor of metastasis. All patients were staged according to FIGO classification for ovarian tumors; 3 of patients had stage IA disease, one of patients had stage IC1 and one of patients had stage IC2. All patients underwent different surgecal procedures which is appropriate for their clinical manifestations. In addition to surgery 2 patients received adjuvant chemotherapy. RESULTS: The median follow-up period of the patients was 60 mounts and recurrence was observed in two patients who were reoperated. We have no patients who died due to this disease. CONCLUSIONS: Possible diagnosis of juvenile granulosa cell tumor should be kept in mind in a patient of young age with unilateral adnexal mass with benign features.

Could the Long-Term Oncological Safety of Laparoscopic Surgery in Low-Risk Endometrial Cancer also Be Valid for the High-Intermediate- and High-Risk Patients? A Multi-Center Turkish Gynecologic Oncology Group Study Conducted with 2745 Endometrial Cancer Cases. (TRSGO-End-001).

This study was conducted to compare the long-term oncological outcomes of laparotomy and laparoscopic surgeries in endometrial cancer under the light of the 2016 ESMO-ESGO-ESTRO risk classification system, with particular focus on the high-intermediate- and high-risk categories. Using multicentric databases between January 2005 and January 2016, disease-free and overall survivals of 2745 endometrial cancer cases were compared according to the surgery route (laparotomy vs. laparoscopy). The high-intermediate- and high-risk patients were defined with respect to the 2016 ESMO-ESGO-ESTRO risk classification system, and they were analyzed with respect to differences in survival rates. Of the 2745 patients, 1743 (63.5%) were operated by laparotomy, and the remaining were operated with laparoscopy. The total numbers of high-intermediate- and high-risk endometrial cancer cases were 734 (45%) patients in the laparotomy group and 307 (30.7%) patients in the laparoscopy group. Disease-free and overall survivals were not statistically different when compared between laparoscopy and laparotomy groups in terms of low-, intermediate-, high-intermediate- and high-risk endometrial cancer. In conclusion, regardless of the endometrial cancer risk category, long-term oncological outcomes of the laparoscopic approach were found to be comparable to those treated with laparotomy. Our results are encouraging to consider laparoscopic surgery for high-intermediate- and high-risk endometrial cancer cases.

Impact of cytoreductive surgery on survival of patients with low-grade serous ovarian carcinoma: A multicentric study of Turkish Society of Gynecologic Oncology (TRSGO-OvCa-001).

BACKGROUND AND OBJECTIVES: The aim of this study was to analyze the factors affecting recurrence-free (RFS) and overall survival (OS) rates of women diagnosed with low-grade serous ovarian cancer (LGSOC). METHODS: Databases from 13 participating centers in Turkey were searched retrospectively for women who had been treated for stage I-IV LGSOC between 1997 and 2018. RESULTS: Overall 191 eligible women were included. The median age at diagnosis was 49 years (range, 21-84 years). One hundred seventy-five (92%) patients underwent primary cytoreductive surgery. Complete and optimal cytoreduction was achieved in 148 (77.5%) and 33 (17.3%) patients, respectively. The median follow-up period was 44 months (range, 2-208 months). Multivariate analysis showed the presence of endometriosis (p = .012), lymphovascular space invasion (LVSI) (p = .022), any residual disease (p = .023), and the International Federation of Gynecology and Obstetrics (FIGO) stage II-IV disease (p = .045) were negatively correlated with RFS while the only presence of residual disease (p = .002) and FIGO stage II-IV disease (p = .003) significantly decreased OS. CONCLUSIONS: The maximal surgical effort is warranted for complete cytoreduction as achieving no residual disease is the single most important variable affecting the survival of patients with LGSOC. The prognostic role of LVSI and endometriosis should be evaluated by further studies as both of these parameters significantly affected RFS.

Is the extent of lymphadenectomy a prognostic factor in International Federation of Gynecology and Obstetrics stage II endometrioid endometrial cancer?

AIM: This study aimed to evaluate the prognostic significance of adequate lymph node dissection (LND) (≥10 pelvic lymph nodes (LNs) and ≥ 5 paraaortic LNs removed) in patients with International Federation of Gynecology and Obstetrics (FIGO) stage II endometrioid endometrial cancer (EEC). METHODS: A multicenter department database review was performed to identify patients who had been operated and diagnosed with stage II EEC at seven centers in Turkey retrospectively. Demographic, clinicopathological, and survival data were collected and analyzed. RESULTS: We identified 284 women with stage II EEC. There were 170 (59.9%) patients in the adequate lymph node dissection (LND) group and 114 (40.1%) in the inadequate LND group. The 5-year overall survival (OS) rate of the inadequate LND group was significantly lower than that of the adequate LND group (84.1% vs. 89.1%, respectively; p = 0.028). In multivariate analysis, presence of lymphovascular space invasion (LVSI) (hazard ratio [HR]: 2.39, 95% confidence interval [CI]: 1.23-4.63; p = 0.009), age ≥ 60 (HR: 3.30, 95% CI: 1.65-6.57; p = 0.001], and absence of adjuvant therapy (HR: 2.74, 95% CI: 1.40-5.35; p = 0.003) remained as independent risk factors for decreased 5-year disease-free survival (DFS). Inadequate LND (HR: 2.34, 95% CI: 1.18-4.63; p < 0.001), age ≥ 60 (HR: 2.67, 95% CI: 1.25-5.72; p = 0.011), and absence of adjuvant therapy (HR: 4.95, 95% CI: 2.28-10.73; p < 0.001) were independent prognostic factors for decreased 5-year OS in multivariate analysis. CONCLUSION: Adequate LND and adjuvant therapy were significant for the improvement of outcomes in FIGO stage II EEC patients. Furthermore, LVSI was associated with worse 5-year DFS rate in stage II EEC.

Adjuvant Treatment Modalities, Prognostic Factors, and Outcome of the Uterine Carcinosarcoma.

OBJECTIVE: To determine the impact of adjuvant therapy and other factors associated with the recurrence and survival of patients with uterine carcinosarcoma (UCS). METHODS: A total of 102 patients who underwhent surgery for UCS from 1998 to 2017 were included in the analysis. Data were analyzed using Kaplan-Meier methods and Cox proportional hazards regression. RESULTS: At 240 months, the actuarial recurrence rate was 34.3%. Distant recurrence was the most common recurrence pattern. Patients with higher CA 125 levels, sarcoma dominance, cervical involvement, advanced stage, no lymphadenectomy, and residual tumour had a significiantly higher risk of recurrence. Five-year disease-free survival (DFS) and overall survival (OS) were 67% and 77%, respectively. FIGO stage was found to be an independent prognostic factor for DFS and OS. Sarcoma dominance was independently associated with decreased OS. CONCLUSION: Sarcoma dominance is associated with poor survival in UCS. Adjuvant treatment was not found to affect recurrence or survival. Given this finding, more effective postoperative strategies are needed.

Management of gynecological cancers in the COVID-19 era: a survey from Turkey

Objective: This study aimed to investigate how gynecologic oncologists modified their patient management during Coronavirus disease-2019 (COVID-19) in Turkey. Material and Methods: An online survey was sent to gynecologic oncology specialists and fellows in Turkey. It included management questions about strategies for newly diagnosed or recurrent endometrial, cervical, ovarian and vulvar cancer during the pandemic. Participants were asked if treatment of these cancers can be delayed or not and, if yes, the duration of delay. Results: 32.9% of surgeons prescribed oral or intrauterine progesterone for early stage, low-grade endometrial cancer. Conversely, 65.7% and 45.7% of the most surgeons did not change their management for early stage high-grade and advanced stage endometrial cancers respectively, as they perform surgery. 58% and 67.1% of the surgeons continued to prefer standard surgical treatment for microinvasive and early stage cervical cancers, respectively. Radiotherapy was preferred administered with hypofractionated doses for locally advanced cervical cancer (57.1%). While 67.1% of surgeons operated early stage ovarian cancer patients, 50% administered neoadjuvant chemotherapy (NACT) to all advanced stage ovarian cancers and 50% administered more cycles of NACT in preference to interval debulking surgery. 93.7% of the surgeons responded that treatment should not be delayed beyond eight weeks. Conclusion: Most Turkish gynecologic oncologists modified their management of gynecologic cancers due to the COVID-19 pandemic. While chemotherapy was preferred for ovarian cancer, postponement of the surgery, with or without non-surgical options, was considered for early stage, low-grade endometrial cancer. Treatment of gynecologic cancers should be decided on a case by case basis, taking into account local COVID-19 infection rates and availability of health facilities. Prognosis is also an important consideration if delay is contemplated. Standard treatment and normal time-frames should be used if possible. If not, a postponement for a maximum of eight weeks or referral to another center were acceptable alternatives.

Enhanced Recovery After Surgery (ERAS) in gynecologic oncology: an international survey of peri-operative practice.

INTRODUCTION: Enhanced Recovery After Surgery (ERAS) programs have been shown to improve clinical outcomes in gynecologic oncology, with the majority of published reports originating from a small number of specialized centers. It is unclear to what degree ERAS is implemented in hospitals globally. This international survey investigated the status of ERAS protocol implementation in open gynecologic oncology surgery to provide a worldwide perspective on peri-operative practice patterns. METHODS: Requests to participate in an online survey of ERAS practices were distributed via social media (WhatsApp, Twitter, and Social Link). The survey was active between January 15 and March 15, 2020. Additionally, four national gynecologic oncology societies agreed to distribute the study among their members. Respondents were requested to answer a 17-item questionnaire about their ERAS practice preferences in the pre-, intra-, and post-operative periods. RESULTS: Data from 454 respondents representing 62 countries were analyzed. Overall, 37% reported that ERAS was implemented at their institution. The regional distribution was: Europe 38%, Americas 33%, Asia 19%, and Africa 10%. ERAS gynecologic oncology guidelines were well adhered to (>80%) in the domains of deep vein thrombosis prophylaxis, early removal of urinary catheter after surgery, and early introduction of ambulation. Areas with poor adherence to the guidelines included the use of bowel preparation, adoption of modern fasting guidelines, carbohydrate loading, use of nasogastric tubes and peritoneal drains, intra-operative temperature monitoring, and early feeding. CONCLUSION: This international survey of ERAS in open gynecologic oncology surgery shows that, while some practices are consistent with guideline recommendations, many practices contradict the established evidence. Efforts are required to decrease the variation in peri-operative care that exists in order to improve clinical outcomes for patients with gynecologic cancer globally.

Does lymph node ratio have any prognostic significance in maximally cytoreduced node-positive low-grade serous ovarian carcinoma?

PURPOSE: To determine the prognostic impact of the lymph node ratio (LNR) in node-positive low-grade serous ovarian cancer (LGSOC). METHODS: We retrospectively reviewed women with LGSOC who had undergone maximal cytoreduction followed by standard chemotherapy in 11 centers from Turkey during a study period of 20 years. Sixty two women with node-positive LGSOC were identified. LNR was defined as the number of metastatic lymph nodes (LNs) divided by the number of total LNs removed. We grouped patients pursuant to the LNR as LNR ≤ 0.09 and LNR > 0.09. The prognostic value of LNR was investigated by employing the univariate log-rank test and multivariate Cox-regression model. RESULTS: With a median follow-up of 45 months, the 5-year progression-free survival (PFS) rates were 61.7% for women with LNR ≤ 0.09 and 32.0% for those with LNR > 0.09 (p = 0.046) whereas, the 5-year overall survival (OS) rates were 72.8% for LNR ≤ 0.09 and 54.7% for LNR > 0.09 (p = 0.043). On multivariate analyses, lymphovascular space invasion (LVSI) (Hazard Ratio [HR] 4.18, 95% confidence interval [CI] 1.88-9.27; p < 0.001), omental involvement (HR 3.48, 95% CI 1.36-8.84; p = 0.009) and LNR > 0.09 (HR 3.51, 95% CI 1.54-8.03; p = 0.003) were adverse prognostic factors for PFS. Additionally, LVSI (HR 6.56, 95% CI 2.33-18.41; p < 0.001), omental involvement (HR 6.34, 95% CI 1.86-21.57; p = 0.003) and LNR > 0.09 (HR 7.20, 95% CI 2.33-22.26; p = 0.001) were independent prognostic factors for decreased OS. CONCLUSION: LNR > 0.09 seems to be an independent prognosticator for decreased survival outcomes in LGSOC patients who received maximal cytoreduction followed by standard adjuvant chemotherapy.

The prevalence of endometrioma and associated malignant transformation in women over 40 years of age.

OBJECTIVE: Endometriosis is an estrogen-dependent chronic disease, which is regarded as a disease of reproductive-aged women. Endometriosis is most frequently diagnosed during reproductive period. We aimed to determine the frequency of endometrioma in women over 40 years of age who were operated for adnexial mass. MATERIALS AND METHODS: A total of 1100 women over 40 years of age underwent surgery for adnexal mass were included in this cohort study between 2006 and 2016. Women who met the criteria were compared regarding the type of adnexial mass, age groups, menopausal status and malignant transformation. RESULTS: A total of 299 women (27.2 %) with benign ovarian mass were determined to have endometrioma. Women with endometrioma were younger and nulliparous more frequently comparing women without endometrioma. Although 20 % of the patients in the endometrioma group were postmenopausal, 70 % of the patients in the control group were postmenopausal. Endometrioma-associated ovarian tumors were developed in nearly 11 % of women with endometrioma. CONCLUSIONS: Even though endometriosis is accepted as a disease of reproductive-aged women, it can occur over 40 years of age. Detailed anamnesis and careful gynecological examination provide key information for differential diagnosis. Accurate information about the risk of malignant transformation should be informed.

SATEN III-Splitting Adjuvant Treatment of stage III ENdometrial cancers: an international, multicenter study.

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.

The use of colposcopic punch biopsy in the management of abnormal cervical cytology: a 5-year retrospective audit.

The aim of this study was to determine the accuracy of colposcopic punch biopsy to detect cervical epithelial neoplasia (CIN) II + in patients with abnormal cervical cytology and the major colposcopic findings in patients who underwent a loop electrosurgical excision procedure (LEEP), subsequently. A total of 231 patients with abnormal cervical cytology who underwent a colposcopy guided cervical biopsy and subsequent LEEP were analysed. The mean age was 33.4 ± 8.7 years. CIN II + rate on LEEP pathology was significantly higher in patients with high-grade cytology, compared to those with a low-grade cytology (92 vs. 55%, p < .0001). CIN II + was found in 80, 98 and 100% of colpocopic biopsies of patients with LSIL, HSIL and AGC, respectively. The overall concordance rate between a colposcopic biopsy and LEEP was 41% with a kappa coefficient. The overall underestimation of CIN II + was 10.5%. On a patient-based analysis, the sensitivity, specificity, PPV and NPV of colposcopic biopsy were 89.4, 47.1, 79.5 and 66%, respectively. More than two cervical biopsies had 100% sensitivity for CIN II + on LEEP pathology. The specificity and PPV decreased with increasing number of cervical biopsies. A see-and-treat strategy may be considered for high-grade cytologies. Patients with a low-grade cytology should be managed with more than two colposcopic biopsies.
