RESUMO
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.
RESUMO
BACKGROUND: Pembrolizumab has shown efficacy in persistent, recurrent, or metastatic cervical cancer. The effect of chemoradiotherapy might be enhanced by immunotherapy. In this phase 3 trial, we assessed the efficacy and safety of adding pembrolizumab to chemoradiotherapy in locally advanced cervical cancer. METHODS: In this randomised, double-blind, placebo-controlled, phase 3 ENGOT-cx11/GOG-3047/KEYNOTE-A18 clinical trial, adults (age ≥18 years) at 176 medical centres in 30 countries with newly diagnosed, high-risk, locally advanced cervical cancer were randomly assigned (1:1) using an interactive voice-response system with integrated web response to receive 5 cycles of pembrolizumab (200 mg) or placebo every 3 weeks plus chemoradiotherapy, followed by 15 cycles of pembrolizumab (400 mg) or placebo every 6 weeks. Randomisation was stratified by planned external beam radiotherapy type (intensity-modulated radiotherapy or volumetric-modulated arc therapy vs non-intensity-modulated radiotherapy or non-volumetric-modulated arc therapy), cervical cancer stage at screening (International Federation of Gynecology and Obstetrics 2014 stage IB2-IIB node positive vs stage III-IVA), and planned total radiotherapy (external beam radiotherapy plus brachytherapy) dose (<70 Gy vs ≥70 Gy equivalent dose in 2 Gy fractions). Primary endpoints were progression-free survival per Response Evaluation Criteria in Solid Tumours version 1.1-by investigator or by histopathologic confirmation of suspected disease progression-and overall survival. Primary analysis was conducted in the intention-to-treat population, which included all randomly allocated participants. Safety was assessed in the as-treated population, which included all randomly allocated patients who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, NCT04221945, and is closed to new participants. FINDINGS: Between June 9, 2020, and Dec 15, 2022, 1060 participants were randomly assigned to treatment, with 529 assigned to the pembrolizumab-chemoradiotherapy group and 531 to the placebo-chemoradiotherapy group. At data cutoff (Jan 9, 2023), median follow-up was 17·9 months (IQR 11·3-22·3) in both treatment groups. Median progression-free survival was not reached in either group; rates at 24 months were 68% in the pembrolizumab-chemoradiotherapy group versus 57% in the placebo-chemoradiotherapy group. The hazard ratio (HR) for disease progression or death was 0·70 (95% CI 0·55-0·89, p=0·0020), meeting the protocol-specified primary objective. Overall survival at 24 months was 87% in the pembrolizumab-chemoradiotherapy group and 81% in the placebo-chemoradiotherapy group (information fraction 42·9%). The HR for death was 0·73 (0·49-1·07); these data have not crossed the boundary of statistical significance. Grade 3 or higher adverse event rates were 75% in the pembrolizumab-chemoradiotherapy group and 69% in the placebo-chemoradiotherapy group. INTERPRETATION: Pembrolizumab plus chemoradiotherapy significantly improved progression-free survival in patients with newly diagnosed, high-risk, locally advanced cervical cancer.

OBJECTIVE: To evaluate oncologic (such as disease-free and overall survival) and obstetric outcomes in patients diagnosed with malignant ovarian germ cell tumors (MOGCTs). METHODS: Patients diagnosed with MOGCTs between March 2007 and February 2022 were evaluated and patients who underwent fertility sparing surgery were included in this retrospective study. The obstetric and oncologic outcomes were evaluated by collecting data up until the patient's last follow-up visit from the hospital records and patient files. The study was approved by Baskent University Institutional Review Board (KA23/124). RESULTS: Seventy FSS patients were included in this study. The median age of the patients was 22.5 years (range: 11-37). The median follow-up time was 92.0 months (10-189). Immature teratoma was the most common histological subtype (32.9%). Bilateral involvement was detected in only one patient with immature teratoma (1.4%). The 5-year DFS rates of immature teratoma, dysgerminoma, yolk sac, and mixed germ cell histologic types were 91.1%, 94.1%, 82.4%, and 88.9%, respectively (P: 0.716). The 5-year OS rates of the same histologic types were 95.7%, 100%, 88.2%, and 88.9%, respectively (P = 0.487). All patients (100%) had a regular menstrual cycle after the completion of adjuvant treatment. The mean time between the last chemotherapy and menstruation was 4.38 months. To date, a total of 34 patients tried to conceive after the completion of disease treatment. A total of 23 (67.6%) patients conceived, resulting in 27 live births in 22 (100%) patients. CONCLUSION: Fertility preservation should be the first treatment option in MOGCTs in young patients due to the unilateral involvement of the disease and its chemosensitive nature.

OBJECTIVE: To evaluate colposcopy performance following the human papillomavirus (HPV) DNA screening program in Turkey. METHODS: Women aged 30-65 years are screened for cervical cancer every 5 years, with individuals positive for HPV 16 and/or 18 or other high-risk HPV types with abnormal cytology referred for colposcopy. Both HPV test and cytology are obtained at the same visit. If HPV is negative, cytology will not be assessed. However, if HPV is positive, both cytology and HPV genotyping will be performed. Colposcopy-require was defined as HPV 16/18 positivity or abnormal smear results with any hrHPV positivity, and the remaining patients (normal smear with hrHPV positivity other than HPV 16/18) were grouped as colposcopy non-required. National data on colposcopy outcomes and unnecessary performance rates in February 2018-2019 were evaluated via a questionnaire. RESULTS: A total of 9808 patients were included, divided based on colposcopy requirement: 5751 (58.6%) patients required colposcopy and 4057 (41.4%) did not. Unnecessary colposcopy was performed on 90.1% of the non-required group (3657 of 4057 patients). In the colposcopy-required group, 4455 patients (79.9%) underwent punch biopsy; 3194 (57.1%), endocervical curettage (ECC); and 421 (7.5%), "see and treat" in the non-required group, the results were 2790 (76.3%), 1957 (53.2%), and 211 (5.7%), respectively. A total of 746 cervical intraepithelial neoplasia (CIN)-3 isolates were detected, including 702 using existing screening and triage with 94.1% sensitivity (702/746). Multiple biopsies were taken in 69.8% (n = 3110) of patients from the colposcopy-required group and 63.7% (n = 1777) from the non-required group. The ECC samples included 19 cervical cancers and 212 ≥CIN-3 lesions in the colposcopy-required group, and four cancers and 41 ≥CIN-3 lesions in the non-required group. The proportion of ≥CIN-3 lesions detected by ECC only was 4.7% (35 of 746 ≥CIN-3 lesions). CONCLUSION: Our results showed high rates of unnecessary colposcopies, and a high percentage of multiple and random punch biopsies and ECC.

Background Postoperative acute kidney injury (AKI) is an important cause of mortality and morbidity among surgical patients. There is little information on the occurrence of AKI after operations for gynecologic malignancies. This study aimed to determine the incidence of AKI in patients who underwent surgery for gynecological malignancies and determine the risk factors in those who developed postoperative AKI. Methodology A total of 1,000 patients were enrolled retrospectively from January 2007 to March 2013. AKI was defined according to the Kidney Disease Improving Global Outcomes 2012 Clinical Practice Guideline for Acute Kidney Injury. Perioperative variables of patients were collected from medical charts. Results The incidence of postoperative AKI was 8.8%, with stage 1 occurring in 5.9%, stage 2 in 2.4%, and stage 3 in 0.5% of the patients. Patients who had AKI were significantly older, had higher body mass index (BMI) higher preoperative C-reactive protein (CRP) levels, and more frequently had a history of distant organ metastasis when compared with those who did not have AKI. When compared with patients who did not develop AKI postoperatively, longer operation times and intraoperative usage of higher amounts of erythrocyte suspension and fresh frozen plasma were seen in those who developed AKI. Conclusions Patients who had AKI were older, had higher BMI with higher preoperative CRP levels, more frequent distant organ metastasis, longer operation times, and higher amounts of blood transfused intraoperatively. Defining preoperative, intraoperative, and postoperative risk factors for postoperative AKI and taking necessary precautions are important for the early detection and intervention of AKI.
RESUMO
BACKGROUND: International guidelines recommend tailoring the radicality of hysterectomy according to the known preoperative tumor characteristics in patients with early-stage cervical cancer. OBJECTIVE: This study aimed to assess whether increased radicality had an effect on 5-year disease-free survival in patients with early-stage cervical cancer undergoing radical hysterectomy. The secondary aims were 5-year overall survival and pattern of recurrence. STUDY DESIGN: This was an international, multicenter, retrospective study from the Surveillance in Cervical CANcer (SCCAN) collaborative cohort. Patients with the International Federation of Gynecology and Obstetrics 2009 stage IB1 and IIA1 who underwent open type B/C1/C2 radical hysterectomy according to Querleu-Morrow classification between January 2007 and December 2016, who did not undergo neoadjuvant chemotherapy and who had negative lymph nodes and free surgical margins at final histology, were included. Descriptive statistics and survival analyses were performed. Patients were stratified according to pathologic tumor diameter. Propensity score match analysis was performed to balance baseline characteristics in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy. RESULTS: A total of 1257 patients were included. Of note, 883 patients (70.2%) underwent nerve-sparing radical hysterectomy, and 374 patients (29.8%) underwent non-nerve-sparing radical hysterectomy. Baseline differences between the study groups were found for tumor stage and diameter (higher use of non-nerve-sparing radical hysterectomy for tumors >2 cm or with vaginal involvement; P<.0001). The use of adjuvant therapy in patients undergoing nerve-sparing and non-nerve-sparing radical hysterectomy was 27.3% vs 28.6%, respectively (P=.63). Five-year disease-free survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 90.1% (95% confidence interval, 87.9-92.2) vs 93.8% (95% confidence interval, 91.1-96.5), respectively (P=.047). Non-nerve-sparing radical hysterectomy was independently associated with better disease-free survival at multivariable analysis performed on the entire cohort (hazard ratio, 0.50; 95% confidence interval, 0.31-0.81; P=.004). Furthermore, 5-year overall survival in patients undergoing nerve-sparing vs non-nerve-sparing radical hysterectomy was 95.7% (95% confidence interval, 94.1-97.2) vs non-nerve-sparing 96.5% (95% confidence interval, 94.3-98.7), respectively (P=.78). In patients with a tumor diameter ≤20 mm, 5-year disease-free survival was 94.7% in nerve-sparing radical hysterectomy vs 96.2% in non-nerve-sparing radical hysterectomy (P=.22). In patients with tumors between 21 and 40 mm, 5-year disease-free survival was 90.3% in non-nerve-sparing radical hysterectomy vs 83.1% in nerve-sparing radical hysterectomy (P=.016) (no significant difference in the rate of adjuvant treatment in this subgroup, P=.47). This was confirmed after propensity match score analysis (balancing the 2 study groups). The pattern of recurrence in the propensity-matched population did not demonstrate any difference (P=.70). CONCLUSION: For tumors ≤20 mm, no survival difference was found with more radical hysterectomy. For tumors between 21 and 40 mm, a more radical hysterectomy was associated with improved 5-year disease-free survival. No difference in the pattern of recurrence according to the extent of radicality was observed. Non-nerve-sparing radical hysterectomy was associated with better 5-year disease-free survival than nerve-sparing radical hysterectomy after propensity score match analysis.

BACKGROUND: Endometrial carcinosarcomas have high malignant potential with a high recurrence rate and poor prognosis. Immunotherapy may be a promising treatment option. The aim of this study is to evaluate the expression of PD-L1/PD-L2 and its relationship to mismatch repair (MMR) protein status and tumor-infiltrating lymphocyte (TIL) density. METHODS: We performed immunohistochemical analyses of PD-L1 (clone 22C3), PD-L2 (clone TY25), MSH-2, MSH-6, PMS-2, and MLH-1 in 77 tumors. We count TILs using CD8 antibody. Clinicopathologic features were recorded and statistically correlated with immunohistochemical results. Kaplan-Meier analyses were used to analyze the prognosis. RESULTS: While PD-L1 positivity was seen more commonly in MMR protein deficient tumors (p = 0.010), PD-L2 positivity was seen more commonly in MMR protein proficient tumors (p = 0.003). PD-L1 positivity was also found to be more common in carcinosarcoma with high TIL infiltration. PD-L2 positivity was associated with decreased overall survival (OS) rates (p = 0.043, p = 0.043, respectively), whereas the PD-L1 positivity and TIL density were not significantly associated with OS rate. The OS rate of patients with MMR protein proficient tumors was significantly lower compared with those with MMR protein deficient tumors (p = 0.042). The lower TILs infiltration was associated with a shorter disease-free survival (DFS) rate. PD-L1 and PD-L2 positivity did not affect the DFS rate. CONCLUSIONS: PD-L1/PD-L2 might be a better target for immunotherapy in endometrial carcinosarcoma. PD-L2 positivity was also associated with a worse clinical outcome in patients with endometrial carcinosarcoma, suggesting that PD-L2 status can be used to predict clinical behavior. Further studies are needed to elucidate the relationship between PD-L1/PD-L2 expression and therapeutic response.

OBJECTIVE: This study aimed to assess the long-term oncologic and obstetric outcomes of women with epithelial ovarian cancer who underwent fertility-sparing surgery. METHODS: A total of 68 patients observed between March 2007 and July 2021 were included in this retrospective study. Unilateral salpingo-oophorectomy and uterine preservation with staging surgery were the main procedures for fertility-sparing surgery. Disease-free, overall survival, and obstetric outcomes were measured as primary outcomes. RESULTS: The median age of the patients was 30.5 years. The median follow-up time was 60.5 months. Disease recurrence occurred in 15 (22.1%) of the patients. Five-year disease-free survival and overall survival (OS) percentages were 75.6% and 83.3%, respectively, for all stages. The FIGO (International Federation of Gynecology & Obstetrics) stage was the only significant factor that affected OS (P = 0.001). Twenty-three patients tried to conceive, and 15 (65.2%) patients became pregnant. Twelve (80%) pregnancies reached term and resulted in 15 live births. Chemotherapy administration and surgical intervention (cystectomy or unilateral salpingo-oophorectomy) showed no difference in pregnancy results (P = 0.806 and P = 0.066, respectively). CONCLUSION: Fertility preservation is safe for invasive epithelial ovarian cancer at early stages for women in the reproductive era. Disease recurrence and OS results are similar to standard treatment at early stages with decent obstetric outcomes.

OBJECTIVE: To evaluate the association of number of radical hysterectomies performed per year in each center with disease-free survival and overall survival. METHODS: We conducted an international, multicenter, retrospective study of patients previously included in the Surveillance in Cervical Cancer collaborative studies. Individuals with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB1-IIA1 cervical cancer who underwent radical hysterectomy and had negative lymph nodes at final histology were included. Patients were treated at referral centers for gynecologic oncology according to updated national and international guidelines. Optimal cutoffs for surgical volume were identified using an unadjusted Cox proportional hazard model, with disease-free survival as the outcome and defined as the value that minimizes the P-value of the split in groups in terms of disease-free survival. Propensity score matching was used to create statistically similar cohorts at baseline. RESULTS: A total of 2,157 patients were initially included. The two most significant cutoffs for surgical volume were identified at seven and 17 surgical procedures, dividing the entire cohort into low-volume, middle-volume, and high-volume centers. After propensity score matching, 1,238 patients were analyzed-619 (50.0%) in the high-volume group, 523 (42.2%) in the middle-volume group, and 96 (7.8%) in the low-volume group. Patients who underwent surgery in higher-volume institutions had progressively better 5-year disease-free survival than those who underwent surgery in lower-volume centers (92.3% vs 88.9% vs 83.8%, P=.029). No difference was noted in 5-year overall survival (95.9% vs 97.2% vs 95.2%, P=.70). Cox multivariable regression analysis showed that FIGO stage greater than IB1, presence of lymphovascular space invasion, grade greater than 1, tumor diameter greater than 20 mm, minimally invasive surgical approach, nonsquamous cell carcinoma histology, and lower-volume centers represented independent risk factors for recurrence. CONCLUSION: Surgical volume of centers represented an independent prognostic factor affecting disease-free survival. Increasing number of radical hysterectomies performed in each center every year was associated with improved disease-free survival.

OBJECTIVE: The "intermediate-risk" (IR) group of early-stage cervical cancer patients is characterized by negative pelvic lymph nodes and a combination of tumor-related prognostic risk factors such as tumor size ≥2 cm, lymphovascular space invasion (LVSI), and deep stromal invasion. However, the role of adjuvant treatment in these patients remains controversial. We investigated whether adjuvant (chemo)radiation is associated with a survival benefit after radical surgery in patients with IR cervical cancer. METHODS: We analyzed data from patients with IR cervical cancer (tumor size 2-4 cm plus LVSI OR tumor size >4 cm; N0; no parametrial invasion; clear surgical margins) who underwent primary curative-intent surgery between 2007 and 2016 and were retrospectively registered in the international multicenter Surveillance in Cervical CANcer (SCCAN) study. RESULTS: Of 692 analyzed patients, 274 (39.6%) received no adjuvant treatment (AT-) and 418 (60.4%) received radiotherapy or chemoradiotherapy (AT+). The 5-year disease-free survival (83.2% and 80.3%; PDFS = 0.365) and overall survival (88.7% and 89.0%; POS = 0.281) were not significantly different between the AT- and AT+ groups, respectively. Adjuvant (chemo)radiotherapy was not associated with a survival benefit after adjusting for confounding factors by case-control propensity score matching or in subgroup analyses of patients with tumor size ≥4 cm and <4 cm. In univariable analysis, adjuvant (chemo)radiotherapy was not identified as a prognostic factor in any of the subgroups (full cohort: PDFS = 0.365; POS = 0.282). CONCLUSION: Among patients with IR early-stage cervical cancer, radical surgery alone achieved equal disease-free and overall survival rates to those achieved by combining radical surgery with adjuvant (chemo)radiotherapy.

The current study highlighted the ARID1A and SALL4 expression and described histopathologic and immunohistochemical features of ovarian seromucinous tumors (SMTs) including borderline tumors (SMBTs) and seromucinous carcinomas (SMC; namely as endometrioid carcinoma with mucinous differentiation according to WHO 2020 classification). The clinicopathological and immunohistochemical features of 38 SMTs were analyzed, including ARID1A, SALL4, estrogen receptor (ER), progesterone receptor (PR), TP53, keratin 7, keratin 20, CEA, CDX2, WT1, PAX2, and PAX8. SMCs and SMBTs comprised 68.4% (n = 26) and 31.6% (n = 12) of all SMTs, respectively, studied. The mean age of diagnosis was 47.4 years and 41.4 years, and the mean size was 9â cm and 7.45â cm for SMC and SMBT, respectively. There was endometriosis or endometriotic cyst in 61.5% of SMCs and 50% of SMBTs. Immunohistochemically, loss of ARID1A staining was observed in 15 (65.2%) of 26 SMCs, and 3 (33.3%) of the 12 SMBTs. Only one SMC showed focal SALL4 positivity. All SMTs were positive for ER, PR, PAX8, and keratin 7. SMTs were negative for WT1, keratin 20, CDX2, and CEA (negative in 66.7% to 92.3% of the cases). While all SMBTs and 24 (92.3%) of 26 SMCs exhibited "wild-type" TP53 staining, 2 (7.7%) SMCs, both were stage III, showed mutant type TP53 overexpression. We indicate there is a similarity between SMC and SMBT according to the immunohistochemical features. SMBTs are keratin 7, ER, PR positive tumors, and some of them have loss of ARID1A expression and are likely to develop in the background of endometriosis similar to SMC.

Immunotherapy involving the programmed death-1 (PD-1)/the programmed death-ligand (PD-1/PD-L) blockade is an understudied tumor therapy approach in cases of adenosarcoma. PD-L1 and PD-L2, and tumor protein p53 (p53) were examined in 20 uterine adenosarcoma cases, and tumor-infiltrating lymphocytes and tumor-associated macrophages were counted in tumor tissue using immunohistochemistry. While CPS PD-L1 positivity with 1% and 10% cut-off values was observed in 40% and 10% of tumors, respectively, CPS PD-L2 positivity with 1%, 10% and 50% cut-off values was observed in 100%, 85% and 50% of the tumors, respectively. The CPS PD-L2 positivity with a 50% cut-off value was positively correlated with tumor grade and the presence of sarcomatous overgrowth and lymphovascular invasion (LVI) (p = 0.025, p = 0.025, and p = 0.025, respectively). Nine of 11 high-grade adenosarcomas and none of the low-grade adenosarcomas showed mutant type p53 expression (p = 0.000). However, PD-L1 expression and tumor-infiltrating immune cells did not correlate with clinicopathological parameters. The CPS PD-L2 positivity with a 50% cut-off value was also positively correlated with mutant type p53 expression (p = 0.024) and tumor-associated macrophages density (p = 0.024). The CPS PD-L2 positivity with a 50% cut-off value and mutant type p53 expression were associated with shorter disease-free survival and shorter overall survival. The high density of tumor-associated macrophages and low density of tumor-infiltrating lymphocytes were also associated with shorter disease-free survival and overall survival (p < 0.05).These results suggested that the CPS PD-L2 positivity with a 50% cut-off value, p53 mutation and tumor microenvironment played an essential role in the progression of uterine adenosarcomas.

OBJECTIVE: The aim of this study is to evaluate the progression-free survival (PFS) of recurrent ovarian cancer (ROC) patients treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (HIPEC). MATERIALS AND METHODS: ROC patients who underwent cytoreductive surgery plus HIPEC between 2015 and 2021 were retrospectively evaluated. Patients' demographic information and clinicopathological characteristics including cancer type, histology, platinum status, presence of ascites, type of surgery, complications, chemotherapy history, and disease progression were documented. PFS was calculated using the Kaplan-Meier method. RESULTS: A total of 104 patients with ROC were included. The median age was 57 years and the median follow-up time was 15 months (range: 5-69 months). In Cox regression multivariate analyses, platinum resistance (hazard ratio [HR]: 3.32, 95% confidence interval [CI]: 1.91-5.76, p = 0.00), more than one relapse prior HIPEC (HR: 2.81, 95% CI: 1.65-4.87, p = 0.024), and presence of ascites (HR: 1.88, 95% CI: 1.08-3.26, p = 0.00) were found to be negative prognostic factors for PFS. In subgroup analyses of patients with the first recurrence, the median PFS was 21 months for platinum-sensitive patients and 6 months for platinum-resistant patients (p = 0.032). CONCLUSION: HIPEC at the time of first platinum-sensitive relapse may lead to favorable PFS in the treatment ROC. However, HIPEC as salvage treatment even with R0 cytoreductive surgery does not seem effective.

OBJECTIVE: Uterine adenosarcoma has low malignant potential, except in cases with sarcomatous overgrowth (SOG) and a high-grade morphology. We here point out the prognostic clinicopathological and immunohistochemical features as well as the microsatellite instability (MSI) status of high- and low-grade adenosarcomas. MATERIAL AND METHOD: In this study, DNA mismatch repair proteins, p16, cyclin D1, ER, PR, and CD10 were examined in uterine adenosarcoma cases using immunohistochemistry. The association between these proteins and clinicopathological parameters was also evaluated. RESULTS: ER, PR and CD10 expressions were lower and weaker in high-grade adenosarcomas with SOG compared to low-grade adenosarcomas without SOG (p < 0.05). p16 positivity was more frequent in high-grade adenosarcomas than low-grade adenosarcomas (p < 0.05). There was no statistically significant difference between cyclin D1 positivity, MSI, and other clinicopathological parameters (p ≥ 0.05). Cyclin D1 positivity and loss of CD10 expression were associated with shorter disease-free survival (DFS). Loss of ER and CD10 expression was associated with shorter overall survival (OS) (p < 0.05). MSI was not associated with DFS or OS (p ≥ 0.05). CONCLUSION: These results suggested that p16 positivity, and loss of ER, PR, and CD10 expression were predictors of high-grade morphology. Additionally, the current study showed that cyclin D1-positive tumors had high recurrence rates; however, no significant relationships were found between MSI and DFS or OS in patients with uterine adenosarcoma. Further investigations are required to determine the importance of p16, cyclin D1, and MSI in uterine adenosarcomas.

INTRODUCTION: Although epithelioid ovarian cancer (EOC) is a radiosensitive tumor and radiotherapy (RT) played a significant role in adjuvant treatment management in the past, the role of RT has evolved with the advent of platinum-based chemotherapy regimens. Nonetheless, modern RT techniques may be useful in certain patients particularly those with recurrent disease. PRESENTATION OF CASE: After surgery and chemotherapy, two patients, aged 57 and 70, presented with recurrent lesions in the parailiac region. The recurrent lesions were treated with high field 1.5-Tesla MR-Linac treatment in 5 fractions at a dose of 30 Gy. The patients tolerated the treatment well and were disease free after 12 and 20 months of magnetic resonance guided radiotherapy (MRgRT), respectively. DISCUSSION: MRgRT is a novel and rapidly evolving technology that allows for the highly precise treatment of even mobile targets through direct visualization of the tumor. The majority of patients with EOC frequently present with abdominal-pelvic recurrences. It has been demonstrated that EOC requires high radiation doses for curative treatment. MR-Linac enables monitoring of organ motion during treatment, which is necessary for delivering higher doses to target volumes while sparing surrounding organs. CONCLUSION: To reduce radiation doses to nearby normal tissues, MRgRT allows for the delivery of hypofractionated RT with tight safety margins. Regardless of initial resistance or gradual development of intolerance to standard chemotherapy regimens, the role of RT in patients with persistent or recurrent EOC should be reconsidered.
RESUMO
OBJECTIVE: To evaluate the feasibility and oncological safety of ovarian preservation in early stage endometrial adenocarcinoma (EC) patients aged 40 and below. METHODS: A total of 11 institutions from eight countries participated in the study. 169 of 5898 patients aged ≤40 years were eligible for the study. Patients with EC treated between March 2007 and January 2019 were retrospectively assessed. RESULTS: The median duration of follow-up after EC diagnosis was 59 months (4-187). Among 169 participants, ovarian preservation surgery (OPS) was performed in 54 (31.9%), and BSO was performed in 115 (68.1%) patients. Although patients younger than 30 years of age were more likely to have OPS than patients aged 30 to 40 years (20.4% vs. 9.6%, P = 0.021), there was no significant difference by the mean age. There were no other relevant baseline differences between OPS and BSO groups. The Kaplan-Meier analysis revealed no difference in either the overall survival (P = 0.955) or recurrence-free survival (P = 0.068) among patients who underwent OPS, and BSO. CONCLUSION: OPS appears to be safe without having any adverse impact on survival in women aged ≤40 years with FIGO Stage I EC.

The aim of the current study was to estimate the incidence of unexpected leiomyosarcoma (LMS) in patients who underwent surgery due to leiomyomas in Konya province, and to contribute to the literature discussing comparisons with similar studies. The digital archives of eight high-volume hospitals were studied for surgeries performed due to leiomyomas between January 2012 and January 2019, and leiomyosarcoma incidence was calculated based on the data obtained. Twenty-one patients in 3703 cases were found to have unexpected leiomyosarcoma, which means we can expect one leiomyosarcoma in 176 (0.56%) surgeries. Six more malignant tumours were detected among the remaining cases. Thus, our study estimated the incidence of unexpected leiomyosarcoma as 1/176 (0.56%), which is higher than most of the studies in the literature justifying the debate started by the FDA in 2014. As the tumour biology is not yet clear, and the incidence of unexpected leiomyosarcoma tends to be so high, the key focus must be to try to detect uterine leiomyosarcomas preoperatively for robust patient care.IMPACT STATEMENTWhat is already known on this subject? The incidence of unexpected leiomyosarcoma varies widely from 1/498 to 1/8300 depending on the study method and the type of procedure, and there is still controversy, even after the FDA statement that led to a major restriction in laparoscopic surgeries due to concerns about inadvertent morcellation of leiomyosarcomas.What do the results of this study add? To the best of our knowledge, the current study found the highest incidence of unexpected leiomyosarcoma, and consequently a serious evaluation of all patients undergoing surgery due to leiomyomas preoperatively considering a leiomyosarcoma candidate is recommended.What are the implications of these findings for clinical practice and/or further research? Studies on tumour biology and novel markers must be supported for accurate preoperative diagnosis of leiomyosarcoma.

A retrospective observational study was carried out in Baskent University School of Medicine, Ankara, Turkey. Recurrent ovarian cancer patients treated between 2007 and 2017 were divided into two groups according to their bevacizumab status. The primary endpoints were overall survival (OS) and safety. Three hundred and ninety-six patients enrolled in this study, 200 (50.5%) received bevacizumab while 196 (49.5%) patients never received bevacizumab. The median follow-up time was 48.2 and 47.6 months, respectively. The 5-year OS was 61% and 46%, respectively (p=.007). In multivariate analysis, only platinum-sensitivity (HR: 3.75, 95% CI: 3.0-5.32; p<.001) was identified as independent prognostic factors. In subgroup analyses according to platinum status, bevacizumab did not affect the 5 year OS in platinum sensitive patients (64% versus 68% p=.28) but increased survival in platinum resistant patients (36% versus 44%, p=.00). The rate of grade III-IV haematologic toxicities was 13.7% in the bevacizumab group and 11% in the other group (p=.6).Impact StatementWhat is already known on this subject? Bevacizumab increases the progression-free survival in platinum-sensitive and resistant recurrent ovarian cancer patients without changing overall survival.What do the results of this study add? Bevacizumab did not affect OS in platinum sensitive recurrent ovarian cancer patients however improved OS in platinum resistant patients with mild toxicity.What are the implications of these findings for clinical practice and/or further research? This study emphasised the crucial role of bevacizumab in the treatment of recurrent ovarian cancer patients.
