Impact of adjuvant treatments and risk factors on survival in 2023 FIGO stage IIB endometrial cancer patients: Turkish Gynecologic Oncology Group Study.

OBJECTIVE: The aim of this study was to investigate the impact of adjuvant treatments, factors influencing recurrence, and survival data in patients with 2023 International Federation of Gynecology and Obstetrics (FIGO) stage IIB endometrial cancer. METHODS: A retrospective analysis was conducted on patients with endometrial cancer who underwent surgery between 2005 and 2022 at seven different centers in Turkey. Demographic, clinicopathological, and survival data were collected and analyzed. RESULTS: Among 7323 patients, 565 (7.7%) were classified as 2023 FIGO stage IIB based on pathological results. Of 565 patients, 214 were followed without receiving adjuvant treatment, while 335 (95.4%) received adjuvant radiotherapy, and 16 (4.6%) received radiotherapy and chemotherapy. The locoregional recurrence rate was higher in patients with a tumor size >4 cm (p=0.038) and myometrial invasion >50% (p=0.045). In patients with distant metastasis, the recurrence rate was lower in those with myometrial invasion <50% compared with myometrial invasion ≥50% (p=0.031). The impact of adjuvant treatment on endometrial cancer patients revealed no significant differences for both disease free survival (p=0.85) and overall survival (p=0.54). Subgroup analyses showed that in patients with deep myometrial invasion, adjuvant treatment was associated with a significant increase in overall survival (p=0.044), but there was no effect on disease-free survival (p=0.12). CONCLUSIONS: Patients with stage IIB endometrial cancer with myometrial invasion ≥50% were more likely to have locoregional and distant metastases. Adjuvant radiotherapy or chemoradiotherapy did not demonstrate an overall survival benefit in these patients.

Factors associated with the involvement of lymph nodes in low-grade serous ovarian cancer.

BACKGROUND AND OBJECTIVES: Evaluating nodal metastases in low-grade serous ovarian cancer (LGSOC) patients. METHODS: Women with LGSOC who had undergone primary cytoreductive surgery comprising systematic pelvic-paraaortic lymphadenectomy were included. Data were obtained retrospectively from 12 oncology centers. RESULTS: One hundred and forty-eight women with LGSOC who had undergone comprehensive surgical staging were included. Seventy-one (48.0%) patients had metastatic lymph nodes. Preoperative serum CA-125 levels of ≥170 U/ml (odds ratio [OR]: 3.84; 95% confidence interval [CI]: 1.22-12.07; p = 0.021) and presence of lymphovascular space invasion (LVSI) (OR: 13.72; 95% CI: 3.36-55.93; p < 0.001) were independent predictors of nodal metastasis in LGSOC. Sixty (40.5%) patients were classified to have apparently limited disease to the ovary/ovaries. Twenty (33.3%) of them were upstaged after surgical staging. Twelve (20.0%) had metastatic lymph nodes. Presence of LVSI (OR: 12.96; 95% CI: 1.14-146.43; p = 0.038) and preoperative serum CA-125 of ≥180 U/ml (OR: 7.19; 95% CI: 1.35-38.12; p = 0.02) were independent predictors of lymph node metastases in apparent Stage Ⅰ disease. CONCLUSIONS: Clinicians may consider to perform a reoperation comprising systematic lymphadenectomy in patients who had apparently limited disease to the ovary/ovaries and had not undergone lymphadenectomy initially. Reoperation may be considered particularly in patients whose preoperative serum CA-125 is ≥180 U/ml and/or whose pathological assessment reported the presence of LVSI.

Open abdomen technique used in complications of major gynecological oncology surgery.

OBJECTIVE: To evaluate the open abdomen technique (laparostomy) used in complications of major gynecological oncology surgery. METHODS: We analyzed retrospectively the surgical database of all patients who had undergone major open surgery by the same gynecologic oncologist over a 5-year period. All patients who had had open abdomen procedure were identified; demographic data and indications of primary surgery, temporary abdominal closure procedure details, fascia closure and morbidity, mortality rates were evaluated. Intraabdominal infection and intraoperative massive hemorrhage were the major indications for all open abdomen cases. Mannheim Peritonitis Index was used perioperatively to determine open abdomen decision in intraabdominal infections. Vacuum Assisted Abdominal Closure system and Bogota Bag were used for temporary abdominal closure techniques. RESULTS: Out of the total 560 patients who had undergone major oncological surgery, 19 patients (3.3%) had open abdomen procedure due to surgical complications. Eleven patients had intraabdominal infection, six patients had hemodynamic instability due to peri and postoperative hemorrhage, two patients had gross fecal contamination during posterior pelvic exenteration surgery. The fascia was closed totally in 15 (78%), partially in 3 (15%) and could not be closed in 1 patient who had died secondary to multiorgan failure. Total morbidity and mortality rates were 26% (5/19) (two intrabdominal abscess, one pulmonary embolism, one skin necrosis, one enteroatmospheric fistula) and 5.2% (1/19) respectively. CONCLUSION: Open abdomen is a life-saving procedure when applied with correct indications and timing. Gynecological oncologic surgeries are candidates to serious complications and gynecologic oncologists dealing with such surgery should be as experienced as general surgeons in this regard.

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.

Carcinosarcoma of the ovary compared to ovarian high-grade serous carcinoma: impact of optimal cytoreduction and standard adjuvant treatment.

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.

Prognostic factors for maximally or optimally cytoreduced stage III nonserous epithelial ovarian carcinoma treated with carboplatin/paclitaxel chemotherapy.

OBJECTIVE: To identify factors predictive of poor prognosis in women with stage III nonserous epithelial ovarian cancer (EOC) who had undergone maximal or optimal primary cytoreductive surgery (CRS) followed by six cycles of intravenous carboplatin/paclitaxel chemotherapy. METHODS: A multicenter, retrospective department database review was performed to identify patients with stage III nonserous EOC who had undergone maximal or optimal primary CRS followed by six cycles of carboplatin/paclitaxel chemotherapy at seven gynecological oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. RESULTS: A total of 218 women met the inclusion criteria. Of these, 64 (29.4%) patients had endometrioid, 61 (28%) had mucinous, 54 (24.8%) had clear-cell and 39 (17.9%) had mixed epithelial tumors. Fifty-five (25.2%) patients underwent maximal CRS, whereas 163 (74.8%) had optimal debulking. With a median follow-up of 31.5 months, the 5-year progression-free survival (PFS) and overall survival (OS) rates were 34.8% and 44.2%, respectively. Bilaterality (hazard ratio [HR] 1.44, 95% CI 1.01-2.056; P = 0.04), age (HR 2.25, 95% CI 1.176-4.323; P = 0.014) and maximal cytoreduction (HR 0.34, 95% CI 0.202-0.58; P < 0.001) were found to be independent prognostic factors for PFS. However, age (HR 2.6, 95% CI 1.215-5.591; P = 0.014) and maximal cytoreduction (HR 0.31, 95% CI 0.166-0.615; P < 0.001) were defined as independent prognostic factors for OS. CONCLUSION: The extent of CRS seems to be the only modifiable prognostic factor associated with stage III nonserous EOC. Complete cytoreduction to no gross residual disease should be the main goal of management in these women.

Prognostic factors and patterns of recurrence in lymphovascular space invasion positive women with stage IIIC endometriod endometrial cancer.

AIM: The purpose of this study was to determine the prognostic factors and patterns of failure in lymphovascular space invasion (LVSI)-positive women with stage IIIC endometrioid endometrial cancer (EC). METHODS: A multicenter, retrospective, department database review was performed to identify LVSI-positive patients with stage IIIC endometrioid EC at five gynecological oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. RESULTS: We identified 172 LVSI-positive women with stage IIIC endometrioid EC during the study period; 75 (43.6%) were classified as Stage IIIC1 and 97 (56.4%) as Stage IIIC2 . The median age at diagnosis was 59 years, and the median duration of follow up was 34.5 months. The total number of recurrences was 46 (26.7%). We observed 14 (8.1%) locoregional recurrences, 12 (7.0%) retroperitoneal failures and 20 (11.6%) distant relapses. For the entire study cohort, 5-year progression-free survival (PFS) was 67.4%, while the 5-year overall survival (OS) rate was 75.1%. Grade 3 histology (hazard ratio [HR] 2.62, 95% confidence interval [CI] 1.34-5.12; P = 0.005), cervical stromal invasion (HR 2.33, 95% CI 1.09-4.99; P = 0.028) and myometrial invasion (MMI) ≥50% (HR 4.0, 95% CI 1.16-13.69; P = 0.028) were found to be independent prognostic factors for decreased OS. CONCLUSION: Uterine factors such as grade 3 disease, cervical stromal invasion and deep MMI seem to be independently associated with decreased OS in LVSI-positive women with stage IIIC endometrioid EC. The high distant recurrence rate in this subgroup of patients warrants further studies in order to identify the most effective treatment strategy for those patients.

Preoperatively Assessable Clinical and Pathological Risk Factors for Parametrial Involvement in Surgically Treated FIGO Stage IB-IIA Cervical Cancer.

OBJECTIVE: Determining the risk factors associated with parametrial involvement (PMI) is of paramount importance to decrease the multimodality treatment in early-stage cervical cancer. We investigated the preoperatively assessable clinical and pathological risk factors associated with PMI in surgically treated stage IB1-IIA2 cervical cancer. METHODS: A retrospective cohort study of women underwent Querleu-Morrow type C hysterectomy for cervical cancer stage IB1-IIA2 from 2001 to 2015. All patients underwent clinical staging examination under anesthesia by the same gynecological oncologists during the study period. Evaluated variables were age, menopausal status, body mass index, smoking status, FIGO (International Federation of Obstetrics and Gynecology) stage, clinically measured maximal tumor diameter, clinical presentation (exophytic or endophytic tumor), histological type, tumor grade, lymphovascular space invasion, clinical and pathological vaginal invasion, and uterine body involvement. Endophytic clinical presentation was defined for ulcerative tumors and barrel-shaped morphology. Two-dimensional transvaginal ultrasonography was used to measure tumor dimensions. RESULTS: Of 127 eligible women, 37 (29.1%) had PMI. On univariate analysis, endophytic clinical presentation (P = 0.01), larger tumor size (P < 0.001), lymphovascular space invasion (P < 0.001), pathological vaginal invasion (P = 0.001), and uterine body involvement (P < 0.001) were significantly different among the groups with and without PMI. In multivariate analysis endophytic clinical presentation (odds ratio, 11.34; 95% confidence interval, 1.34-95.85; P = 0.02) and larger tumor size (odds ratio, 32.31; 95% confidence interval, 2.46-423.83; P = 0.008) were the independent risk factors for PMI. Threshold of 31 mm in tumor size predicted PMI with 71% sensitivity and 75% specificity. We identified 18 patients with tumor size of more than 30 mm and endophytic presentation; 14 (77.7%) of these had PMI. CONCLUSIONS: Endophytic clinical presentation and larger clinical tumor size (>3 cm) are independent risk factors for PMI in stage IB-IIA cervical cancer. Approximately 78% of the patients with a tumor size of more than 3 cm and endophytic presentation will require adjuvant chemoradiation for PMI following radical surgery. Considering clinical tumor presentation along with tumor size can enhance the physician's prediction of PMI in early-stage cervical cancer.

The influence of the systematic birth preparation program on childbirth satisfaction.

PURPOSE: The primary purpose of this study was to assess the influence of a systematic multidisciplinary birth preparation program on satisfaction with childbirth experience. A secondary aim was to detect factors that affect the childbirth satisfaction. METHODS: In this prospective study, 77 pregnant women who completed the 4-month birth preparation program (Group 1) and 75 women in the control group (Group 2) were asked to fill out two questionnaires with face-to-face interviews within 48 h after labor. One of the questionnaires was the translated form of Salmon's Item List German (SIL-Ger), and SIL-Ger scores ≥70 was accepted as a satisfactory experience. RESULTS: There was no statistically significant difference between the groups in terms of sociocultural and intrapartum characteristics, and obstetric outcome parameters. The women who received antenatal education experienced significantly less pain (p = 0.01), had a better communication with midwife or obstetrician during delivery (p = 0.001), and participated more actively in decision-making before, during, and after childbirth (p < 0.001 for all). SIL score was significantly higher in Group 1 (105.7 ± 2.2 vs 80 ± 2.5, p < 0.01), and significantly more women had a SIL score ≥70 (96.1 vs 73.3%, p < 0.01). In multivariate logistic regression model, attending the birth preparation program and the level of pain perceived during labor were found to have a significant effect on the birth satisfaction. CONCLUSION: Systematic birth preparation program improves satisfaction with childbirth experience by enabling women to communicate better with healthcare providers and to participate in decision-making during labor, as well as by decreasing the perception of labor pain.

Could body mass index be an indicator for endometrial biopsy in premenopausal women with heavy menstrual bleeding?

PURPOSE: To evaluate the role of body mass index (BMI) in women with premenopausal heavy menstrual bleeding (HMB) to identify patients who should undergo endometrial biopsy. METHODS: This prospective cohort study included 1120 premenopausal women who presented to the Gynecology Clinic, Bakirkoy Dr. Sadi Konuk Training and Research Hospital in Istanbul, Turkey, due to HMB and who underwent endometrial sampling. The abnormal endometrial histopathological results were analyzed by separating patients into groups of all abnormal findings (hyperplasia without atypia + hyperplasia with atypia + carcinoma) and hyperplasia with atypia + carcinoma. Sensitivity and specificity of the abnormal histopathological results were calculated in both groups using BMI cut-off values as 25, 30 and 35 and age cut-offs as 40 and 45 years. RESULTS: The rate of hyperplasia with atypia and carcinoma was sevenfold higher in women with a BMI ≥30 compared to those with a BMI ≤30 (95 % CI 2.4-17.9). In the analyses, BMI was a stronger risk factor in women younger than 45 years of age. The risk of endometrial carcinoma and atypical hyperplasia was twofold higher in patients older than 45 years when compared with patients younger than 45 years (95 % CI 1.1-5.1). CONCLUSIONS: All women with a BMI ≥30 and presenting premenopausal HMB should undergo endometrial biopsy regardless of age.

Clinical, pathological and (18)F-FDG PET/CT findings in synchronous primary vaginal and endometrial cancers.

Synchronous primary gynecologic malignancies are infrequently seen. In this report, we describe the clinical, pathological and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) findings of a patient with synchronous primary vaginal and endometrial cancers. To our knowledge, this is the first such case described in the literature.

Should omentectomy be a part of surgical staging in patients with endometrioid adenocarcinoma of the uterine corpus?

BACKGROUND: The purpose of the study was to determine the prevalence of omental metastasis in endometrioid adenocarcinoma and to correlate risk variables with this spread. METHODS: A retrospective analysis of patients with endometrioid adenocarcinoma who underwent omentectomy in addition to staging laparotomy was performed. RESULTS: Omental metastases were noted in 11 of the 322 patients with endometrioid adenocarcinoma (3.4%). Multivariate analyses showed that there was a significant correlation between omental metastasis and positive peritoneal cytology, adnexal involvement, and grade 3 tumor (p = 0.028, p = 0.001, and p = 0.01, respectively). There was no statistical relationship between omental metastasis and lymphovascular space involvement, deep myometrial invasion, and lymph node metastasis (p = 0.087, p = 0.97, and p = 0.92, respectively). CONCLUSION: Grade 3 endometrioid adenocarcinomas, especially those that are complicated by deep myometrial invasion, have a pattern of intra-abdominal spread similar to more aggressive endometrial cancers, with frequent involvement of the omentum. Overall, we conclude that 37.5% (3/8) of patients who had a grade 3 tumor and omental metastasis stage IV disease would have been missed if a staging operation similar to that employed for ovarian cancer had not been performed.

Is there an appropriate cutoff age for sampling the endometrium in premenopausal bleeding?

AIM: To determine a cutoff age for endometrial evaluation in premenopausal abnormal uterine bleeding (AUB). METHODS: Histopathology reports of endometrial sampling performed due to AUB in women aged 50 years or less were reviewed retrospectively. Histopathological findings were categorized into three groups as follows: group 1: hyperplasia without atypia + hyperplasia with atypia + malignancy, group 2: hyperplasia with atypia + malignancy, and group 3: malignancy. RESULTS: Data from 2,516 patients were analyzed for this study. Overall, 13.5% of patients had endometrial hyperplasia without atypia, 1% of patients had hyperplasia with atypia and 0.6% of patients had malignant disease. Logistic regression revealed a significant difference in the odds ratios of group 1 in the age ranges of 40-45 and 45-50 years compared with <40 years (p = 0.001 and p = 0.01, respectively). There were no significant differences between the age groups for the odds ratio of group 2 and group 3. CONCLUSION: There is no cutoff age for sampling the endometrium in order to detect hyperplasia with atypia and cancer in premenopausal women with AUB. Therefore, the management of AUB should be tailored to each patient regardless of age, incorporating all risk factors for malignant disease.

Role of subcutaneous closure in preventing wound complications after cesarean delivery with Pfannenstiel incision: a randomized clinical trial.

AIM: The aim of this study was to evaluate the role of suture closure of the subcutaneous tissue in preventing wound complications after cesarean section with a Pfannenstiel incision, and to investigate factors associated with wound complications. MATERIAL AND METHODS: Patients undergoing cesarean delivery were randomly assigned to either suture closure or non-closure of the subcutaneous tissue. The participants were invited to two follow-up examinations at the 1st and 4th postoperative weeks for the detection of wound complications. The two main outcomes were composite wound complication and superficial wound separation. Factors associated with wound complications were analyzed using multiple logistic regression. RESULTS: During the study period, a total of 361 patients (176 in the closure group, 185 in non-closure group) were analyzed. Composite wound complication occurred in 23.3% (41/176) of the closure group, and in 20% (37/185) of the non-closure group with no significant difference (P = 0.44). Wound separation occurred in 2.3% (4/176) of the closure group and 1.6% (3/185) of the non-closure group without any significant differences (P = 0.64). None of the factors were found to be associated with the rate of composite complication. The significant factors found to be associated with wound separation were subcutaneous tissue thickness of 4 cm or more (P = 0.01) and maternal diabetes mellitus (P = 0.01), however they lost their significance in multivariate analyses. CONCLUSION: The rate of wound complications, including superficial wound separation, did not differ according to the subcutaneous closure in cesarean delivery with Pfannenstiel incision. It is not possible to predict wound complications using previously defined clinical and operative risk factors, including subcutaneous tissue thickness.

Lymph node metastasis in patients with epithelial ovarian cancer macroscopically confined to the ovary: review of a single-institution experience.

BACKGROUND: To evaluate the patterns of lymphatic spread in epithelial ovarian cancer (EOC) macroscopically confined to the ovary and to determine risk factors for lymph node metastasis. MATERIALS AND METHODS: All patients with clinically apparent stage IA/B/C EOCs who underwent staging surgery between January 2003 and February 2013 were retrospectively identified. RESULTS: Two hundred and thirty-six (n = 236) consecutive patients were operated for primary epithelial ovarian carcinoma. Sixty-two of these patients (26.2 %) who underwent a comprehensive staging procedure including pelvic and paraaortic lymphadenectomy were diagnosed with tumors confined to one or two ovaries (stage IA/B/C). Of these 62 patients, 17 (27.4 %) had upstaged disease and 8 (12.9 %) had lymph node metastasis. Tumor histology was serous in 25 patients (40.3 %), mucinous in 23 patients (37 %), endometrioid in 9 patients (14.5 %), and clear cell in 5 patients (8 %). Positive lymph node status was found in 20 % (5/25) of those with serous histology while this rate was only 8.1 % (3/37) in those with non-serous disease. Although the presence of ascites was not associated with an increased risk of lymph node involvement (p = 0.24), positive peritoneal cytology (p = 0.001) and grade 3 disease (p = 0.001) were significant predictors of lymph node involvement. CONCLUSION: All patients diagnosed with EOC macroscopically confined to the ovary should be considered for comprehensive staging surgery including pelvic and paraaortic lymphadenectomy.

Female sexual function and associated factors during pregnancy.

AIM: The objective of this study was to assess the changes in female sexual function during pregnancy and to identify associated factors among Turkish population using a validated questionnaire. Furthermore, we aimed to examine Turkish pregnant women's beliefs regarding sexual activity and describe their source of information about sexuality during pregnancy. MATERIAL AND METHODS: In this cross-sectional study, healthy heterosexual pregnant women who had been living with their partners within the last four weeks were asked to complete two self-administered questionnaires, one of which was Female Sexual Function Index (FSFI). RESULTS: A significant association was found between the decrease in intercourse frequency and trimesters, as a decline in frequency was reported by 58.3%, 66.1% and 76.5% of women in each trimester, respectively (P = 0.01). Only the trimester of gestation and employment status were independent factors associated with the decline in sexual intercourse frequency during pregnancy. When the overall FSFI score were compared according to each trimester of pregnancy, there were no statistical significant differences between the first and second trimesters (P = 0.71). The overall FSFI score in the third trimester was found to be significantly lower than the overall scores in the first two trimesters (P < 0.001 for both). In linear regression analysis, overall FSFI scores were adversely affected by only being in the last trimester. 38.7% of women and 36.2% of male partners worried that sexual intercourse may harm the pregnancy. Among the total sample, only 23.8% of women discussed sexuality with the medical staff. CONCLUSION: The third trimester is the independent variable for both decreased sexual activity frequency and sexual function scores in pregnancy. Counseling about sexuality during pregnancy is not frequent in the clinical setting, but conversations about this topic should happen on a regular basis during prenatal care visits.

Single square hemostatic suture for postpartum hemorrhage secondary to uterine atony.

OBJECTIVE: The objective of this study is to describe a novel technique for the treatment of postpartum hemorrhage and evaluate its effectiveness and safety. METHODS: Single square hemostatic suture was performed for uterine atony when postpartum hemorrhage did not respond to medical therapy and bilateral uterine artery ligation. We retrospectively reviewed the data of 11 women and evaluated their endometrial cavity with hydrosonography after a follow-up period of 8-34 months. RESULTS: The single square hemostatic suture successfully stopped bleeding in all of the cases. Of the 11 women, 2 could not be traced. Menstruation started without delay in nine women. One of the women achieved pregnancy 25 months after surgery. The six women who underwent hydrosonography had an intact endometrial cavity. CONCLUSIONS: For women who desire future fertility, and when bilateral uterine artery ligation is not sufficient to control PPH, single square suturing may be used as an effective and safe procedure.

Ovarian fibroma/fibrothecoma: retrospective cohort study shows limited value of risk of malignancy index score.

BACKGROUND: Ovarian fibromas/fibrothecomas are uncommon benign tumours of ovary. Due to their solid structure, these benign tumours are sometimes confused with malignant tumours during clinical evaluation. AIMS: To determine the clinico-pathological characteristics of ovarian fibroma/fibrothecoma and analyse the efficiency of risk of malignancy index (RMI) scoring system to distinguish malignancy among these tumours. METHODS: Between November 2001 and February 2012, women with a pathological diagnosis of ovarian fibroma/fibrothecoma were identified. Depending on the menopausal status, serum CA-125 level and ultrasonographic findings, RMI scores were calculated for each of the patients. RESULTS: During the study period, 43 ovarian fibroma/fibrothecoma (4.7%) were detected among 912 adnexal masses operated. The mean age of the women was 52.2 (range, 21-80 years). Upon calculating RMI scores, 33 women (76.7%) were classified as low risk and 10 women (23.3%) as high risk for malignancy. Sensitivity, specificity, positive predictive value and negative predictive value of the RMI scoring for identification of malignant lesions preoperatively were found as 0%, 76%, 0% and 97%, respectively. Final pathological diagnosis was ovarian fibroma in 13 (30%) women, fibrothecoma in 29 (67%) and fibrosarcoma in one woman (2%). CONCLUSION: There are no specific markers for accurate preoperative diagnosis of ovarian fibroma/fibrothecoma. Moreover, according to our results, RMI scoring system does not aid clinicians in this issue either, with a high false-positive rate and very low sensitivity. Further studies with higher number of cases are needed to state clearly the role of RMI scores in preoperative discrimination of malignancy.

Evaluation of endocervical canal in women with minimal cervical cytological abnormalities.

OBJECTIVE: This study aimed to examine the endocervical canal curettage (ECC) results of patients with atypical squamous cells of undetermined significance (ASC-US) or low-grade intraepithelial lesion (LSIL) and secondarily to explore the features of patients who are at greatest risk for endocervical involvement. MATERIALS AND METHODS: This is a retrospective analysis of 846 women who underwent ECC with ASC-US or LSIL on cervical cytology between January 2003 and April 2011. Records of demographic data and colposcopic impression were evaluated. Histopathological results of biopsies and ECC were classified into 2 categories as less than cervical intraepithelial lesion 2 (CIN 2) and CIN 2+ lesions for comparison. Multivariate analysis was performed using binary logistic regression analysis to identify predictors of ECC results. RESULTS: CIN 1 lesions were detected in 8.9% of patients, and the rates of CIN 2 or 3 and invasive/microinvasive cancers in ECC were 3.8% and 0.7%, respectively. Cervical intraepithelial lesion 2 or worse lesions were detected in 1.6% (7/419) of the patients with normal colposcopic findings. There was no statistically significant difference in the rate of CIN 2+ lesion in endocervical canal between the patients with or without satisfactory colposcopic examination (4.4% vs 4.1% p = .69). A total of 1.7% of the patients who did not have cervical biopsy and also 1.1% of the patients who had less than CIN 2 biopsy results were diagnosed with CIN 2+ lesion by ECC despite the satisfactory colposcopy. Only a positive biopsy result for dysplasia was found to be an independent factor for the detection of a dysplastic lesion in endocervical canal (odds ratio = 0.06; 95% CI = 0.01-0.35; p = .02). CONCLUSIONS: Endocervical canal curettage had minimal diagnostic utility for the detection of CIN 2 or worse lesions in women with ASC-US or LSIL smear result and normal colposcopic findings. In addition to this, the presence or absence of CIN 2+ lesions diagnosed by means of endocervical curettage was independent of a satisfactory or unsatisfactory colposcopic examination.

Clinicopathological and Survival Characteristics of Mismatch Repair Status and PD-1 Expression in Serous Ovarian Cancer.

OBJECTIVE: To evaluate the clinicopathological characteristics of mismatch repair (MMR) deficiency and its clinical outcomes by performing immunohistochemistry (IHC) for MMR genes in the serous ovarian cancer (SOC) tumour sections. STUDY DESIGN: A retrospective case-control study. Place and Duration of the Study: Gynecology Department of Kanuni Sultan Süleyman Training and Research Hospital, and Department of Medical Oncology of Medipol University, between March 2001 and January 2020. METHODOLOGY: IHC was carried out for MLH1, MSH2, MSH6, and PMS2 on full-section slides from 127 SOCs to evaluate the MMR status. MMR-negative and MMR-low groups together were defined as MMR deficient and called microsatellite instability-high (MSI-H). The MSI status and expression of programmed cell death-1 (PD-1) were compared in SOCs with different MMR statuses. RESULTS: A significantly higher frequency of MMR-deficient SOCs was diagnosed at early stages compared with the patients in the MSS group (38.6% and 20.6%, respectively, p=0.022). The frequency of cases with PD-1 expression was significantly higher in the MSI-H group (76.2%) than in the MSS counterparts (58.8%, p=0.028). Patients in the MSI-H group had significantly longer DFS (25.6 months) and OS (not reached) than those in the MSS group (16 months and 48.9 months, p=0.039 and p=0.026, respectively). CONCLUSION: MSI-H SOCs were diagnosed at an earlier stage as compared to MMR proficient cases. The presence of PD-1 expression was significantly higher in cases presenting MMR deficiency compared with MMR-proficient cases. MSI status was significantly associated with DFS and OS.
