- Abstract
Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of patients and the quality of the study. Strict morphologic criteria should be applied to the candidates to maintain oncological safety. When limited to a tumor less than 2 cm in diameter, the overall recurrence rate after vaginal RT is 3% to 6% and the death rate is 2% to 5%. Data on fertility and obstetric outcome are mostly based on the results of patients who underwent vaginal RT. More data are needed to be able to draw the same conclusions for abdominal RT. Fertility seems not to be decreased, but the risk for premature delivery is 2 to 3 times higher compared to women with an intact cervix. In locally advanced cervical tumors with a diameter larger than 2 cm, neoadjuvant chemotherapy followed by RT may be offered after explaining the experimental nature to the patient. In conclusion, RT is an oncologically safe technique in women with early invasive cancer. The rate of term pregnancies still needs improvement. Fertility-preserving treatment of women with tumors larger than 2 cm in diameter can be done by combining neoadjuvant chemotherapy and trachelectomy; however, experience is still limited.

Primary leiomyoma of the ovary, which is of unknown origin, is an extremely rare tumor of ovary. We report a rare case of giant primary ovarian leiomyoma with an unusual presentation, ascites, elevated CA125 and discuss the preoperative imaging findings. A 45-year-old woman was referred for evaluation of an adnexal mass of 8 x 9 cm with ascites and elevated CA125 levels. Preoperative imaging studies were in accordance with fibroma/thecoma. At laparotomy total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Histological and immunhistochemical examination revealed primary ovarian leiomyoma.

Purpose: Surgical staging in early endometrial cancer is not universally done and lymphadenectomy in early-stage disease is controversial. Aim of the present study was to evaluate surgical staging in patients with endometrioid histology, FIGO Stage IA endometrial cancer. Materials and Methods: Eighty-seven patients with FIGO Stage IA, low-risk patients were included in the study. Staging surgery group included patients who had comprehensive surgical staging (hysterectomy, oophorectomy, and pelvic lymph node dissection with or without para-aortic lymph node dissection). Non-staging surgery group included patients who had hysterectomy, and bilateral oophorectomy with or without lymph node sampling. Two groups were compared for lymph node status, occult cervical involvement, other prognostic factors, and outcome were analyzed. Results: In total 17.2% of patients were upstaged in final pathological examination; 12.9% in non-staging surgery group and 24.2% in staging surgery group. Upstaging was due to lymph node involvement (6%), cervical stromal invasion (13.7%), and myometrial invasion greater than 50% (1.1%). Median pelvic lymph node number was 23 and pelvic lymph node metastases was found in 3% of the patients. Median para-aortic lymph node number was 11.5 and there was one isolated para-aortic lymph node metastases (5.8%). Conclusion: Of the patients, 17.2% had stage migration. Until the issue is solved by future studies, surgical staging might be considered standard surgery for endometrial cancer. [ABSTRACT FROM AUTHOR]

Our aim was to investigate the hypoglycaemic and antioxidant effects of the Helichrysum plicatum ssp. plicatum ( HPsP) plant extract in the streptozotocin-induced type 1 diabetes rat model during pregnancy. Five groups ( n = 8, each) were formed: (1) diabetic non-mated control, (2) non-diabetic mated control, (3) diabetic mated control, (4) diabetic non-mated treatment and (5) diabetic mated treatment. The HPsP extract was administered orally for 15 days (250 mg/kg body weight), beginning 3 days before mating. The extract led to decreased blood glucose, increased serum insulin, and decreased serum triglycerides in pregnant and non-pregnant diabetic animals. Liver thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) measurements in extract-treated diabetics were similar to non-diabetic pregnant controls, indicating probable reversal of increased lipid peroxidation in the liver. The mean pup number tended to increase ( p = 0.06) with extract administration. In conclusion, the beneficial effects we encountered with the periconception use of the studied herbal extract warrant further investigation. [ABSTRACT FROM AUTHOR]

- Abstract
Uterine tumors resembling ovarian sex cord tumors (UTROSCTs) are very rare uterine neoplasms. They mostly behave in a benign fashion but cases were reported with extra-uterine spread. There are less than 50 cases reported in the literature so far according to the present authors' knowledge. We report a case of 45-year-old woman with UTROSCT concurrent with adenomyosis and complex hyperplasia with atypia of endometrium and her three-year follow up. [ABSTRACT FROM AUTHOR]

Aim: To compare the seropositivity rate of cancer patients with non-cancer controls after inactive SARS-CoV-2 vaccination (CoronaVac) and evaluate the factors affecting seropositivity. Method: Spike IgG antibodies against SARS-CoV-2 were measured in blood samples of 776 cancer patients and 715 non-cancer volunteers. An IgG level ≥50 AU/ml is accepted as seropositive. Results: The seropositivity rate was 85.2% in the patient group and 97.5% in the control group. The seropositivity rate and antibody levels were significantly lower in the patient group (p, Plain language summary Cancer patients are at high risk for infection with SARS-CoV-2 and of developing the associated disease, COVID-19, which therefore puts them in the priority group for vaccination. This study evaluated the efficacy and safety of CoronaVac, an inactivated virus vaccine, in cancer patients. The immune response rate, defined as seropositivity, was 85.2% in the cancer patient group and 97.5% in the control group. The levels of antibodies, which are blood markers of immune response to the vaccine, were also significantly lower in the patient group, especially in those older than 60 years and receiving chemotherapy. These results highlight the importance of determining the effective vaccine type and dose in cancer patients to protect them from COVID-19 without disrupting their cancer treatment.

PURPOSE: To evaluate the practice patterns among centers and physicians worldwide regarding sentinel lymph node biopsies (SLNB) in cervical cancer (CC) patients. METHOD: A validated 35-item questionnaire regarding SLNB in CC supported by the Gynecologic Cancer Intergroup (GCIG), and sponsored by the North-Eastern German Society of Gynaecologic-Oncology (NOGGO) was sent to all major gynecological cancer societies across the globe for further distribution from October 2015 and continued for a period of 7 months. RESULTS: One hundred and sixty-one institutions from around the world participated. One hundred and six (66%) of the participants were from university centers and one hundred and eleven (69%) were gynecologic oncologists. One hundred and fifty-two (97%) performed lymphadenectomy (LNE), and one hundred and forty-seven (94%) did so systematically; Ninety-seven (60%) used SLNB, due to lower morbidity (73%), reliability (55%) and time-saving (27%). In cases of positive SLNB (pN+), 39% of respondents stopped the operation and sent the patient for chemoradiation (CRT), 45% completed pelvic and paraaortic LNE, whereas 26% went on to perform a radical hysterectomy (RH) and systematic pelvic and paraaortic LNE. In case of negative SLNB (pN0), 39% of institutions still performed a systematic pelvic and paraaortic LNE. CONCLUSION: In this survey worldwide SLNB adoption is an encouraging 60%, yet ample differences exist regarding strategy, and to a lower extent the techniques used. Lack of experience is the most common reason SLNB is not performed. Efforts to increase surgical education on SLNB technique and multicenter prospective trials providing evidence-based guidelines are warranted.

OBJECTIVE: To evaluate the association of three patho-gnomonic criteria, inner border, ridge sign, and rag sign with high-grade cervical intraepithelial neoplasia (CIN) using video exoscopy. METHODS: Retrospective evaluation of video recordings of 335 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and, if indicated loop excisions, was performed. The most severe histologic diagnosis was recorded. Sensitivity, specificity, positive, negative predictive value, and likelihood ratios for highgrade CIN were calculated. RESULTS: In 285 patients (85%), a single colposcopy directed biopsy was taken; 50 patients (15%) underwent two biopsies. One hundred sixty-two patients (48%) underwent subsequent magnification-guided loop excision. Sensitivity, specificity, positive predictive value, and negative predictive value of the inner border to detect high-grade CIN were 20%, 99%, 97.9%, and 34.8%, respectively. The positive likelihood ratio (LR+) was 20.3 and the negative likelihood ratio (LR2) was 0.81. Sensitivity, specificity, positive predictive value, and negative predictive value of the ridge sign to detect high-grade CIN were 52.5%, 96.4%, 96.8%, and 46.6%, respectively. The LR+ ratio was 13.2 and the LR-ratio was 0.49. Sensitivity, specificity, positive predictive value, and negative predictive value of the rag sign to detect high-grade CIN were 38.4%, 96%, 95.7%, and 40.2%, respectively. The LR+ ratio was 9.7 and the LR-ratio was 0.6. Only the ridge sign showed a correlation with young age. Presence of any two signs significantly increased the LR of the presence of high-grade CIN. CONCLUSION: The inner border, ridge sign, and the newly defined rag sign are objective, effective colposcopic signs and are significantly associated with high-grade CIN. © 2013 by The American College of Obstetricians and Gynecologists.

Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of patients and the quality of the study. Strict morphologic criteria should be applied to the candidates to maintain oncological safety. When limited to a tumor less than 2 cm in diameter, the overall recurrence rate after vaginal RT is 3% to 6% and the death rate is 2% to 5%. Data on fertility and obstetric outcome are mostly based on the results of patients who underwent vaginal RT. More data are needed to be able to draw the same conclusions for abdominal RT. Fertility seems not to be decreased, but the risk for premature delivery is 2 to 3 times higher compared to women with an intact cervix. In locally advanced cervical tumors with a diameter larger than 2 cm, neoadjuvant chemotherapy followed by RT may be offered after explaining the experimental nature to the patient. In conclusion, RT is an oncologically safe technique in women with early invasive cancer. The rate of term pregnancies still needs improvement. Fertility-preserving treatment of women with tumors larger than 2 cm in diameter can be done by combining neoadjuvant chemotherapy and trachelectomy; however, experience is still limited.

Purpose: To evaluate the clinical value of four objective colposcopic criteria inner border, ridge sign, cuffed crypt openings and rag sign to diagnose cervical intraepithelial neoplasia grade 2 or worse (CIN 2+), using video exoscopy and to compare it to subjective graduating signs. Methods: Retrospective evaluation of video recordings of 444 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and if indicated loop excisions. Most severe histological diagnosis was recorded. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LR) with 95 % confidence interval, for CIN 2+ were calculated. Results: Single biopsy, two biopsies and magnification-guided loop excision were performed in 60.8, 39.2 and 70.5 % of patients, respectively. Sensitivity, specificity, PPV and NPV to detect CIN 2+ were 19.3, 99.2, 98.3 and 35.8 %, for inner border sign; 53.1, 93.5, 94.7 and 47.6 %, for ridge sign; 51.5, 84.9, 88.2, and 44.3 %, for cuffed crypt openings, and 40.7, 96.4, 96.1 and 42.5 %, for rag sign, respectively. The positive likelihood ratio (LR+) was 26.7 and the negative likelihood ratio (LR−) was 0.81, for inner border sign; 8.2 and 0.5, for ridge sign; 3.41 and 0.57 for cuffed crypt openings; and 11.3 and 0.62 for rag sign, respectively. 90 % of CIN 2+ had at least one objective sign. Combination of any two objective signs significantly increased the LR of the presence of CIN 2+, and was clinically superior to any combination of graduating signs. Conclusion: Objective colposcopic criteria are clinically useful and significantly associated with CIN 2+.

ObjectiveIndividualized treatment of pregnant patients with cervical cancer is mandatory; hence, information on nodal status is pivotal to allow a waiting strategy in early-stage disease.We aimed to verify the oncological safety and surgical reproducibility of a standardized laparoscopic pelvic lymphadenectomy in pregnant patients with cervical cancer.MethodsWe standardized laparoscopic pelvic lymphadenectomy during the first and second term of gestation in 32 patients with cervical cancer since 1999. According to gestational week (GW) of less than 16 GWs or more than 16 GWs, 2 different techniques were used.ResultsThe International Federation of Gynecology and Obstetrics stages were IA in 10 patients, IB1 in 17 patients, IB2 in 4 patients, and IIA in 1 patient. Mean (SD) GW was 17.5 (5.1) weeks. Mean (SD) operative time was 105.4 (29) minutes. Mean (SD) blood loss was 5.3 (10.2) mL. There were no conversion to laparotomy and no intraoperative complications. A median number of 14 pelvic lymph nodes (range, 8–57) were harvested. Median hospital stay was 6 days. Median follow-up is 42.5 months (range, 17–164). Four patients had lymph node metastases. Five patients interrupted their pregnancy. Fourteen patients were given neoadjuvant platin-based systemic therapy. All patients are alive and disease free. All children born through cesarean delivery at a mean (SD) 34 (1.9) GWs are well and show normal clinical neurological development.ConclusionsTo the best of our knowledge, this is the largest series so far reported on laparoscopic pelvic lymphadenectomy during pregnancy. This procedure is safe and associated with good oncological and obstetrical outcomes.

Purpose: To compare loop excisions of cervical intraepithelial neoplasia grade 2 or worse (CIN 2+) under video exoscopy, or colposcopic guidance, with respect to safety and effectiveness. Methods: Prospective multicentric randomized trial of 300 patients, undergoing loop excision for CIN 2+ either under video exoscopy (group A) or colposcope (group B) guidance. Intra- and post-operative complications, resection margins, and removed cervical volume in both groups were evaluated. Results: 19.3% of patients in video exoscopy group and 15.5% in colposcopy group (p = 0.67) had transformation zone (TZ) 3. 45/151 (29.8%) of group A patients and 48/149 (32.2%) of group B patients underwent top-hat procedure, i.e., one superficial excision followed by one deeper removal of the endocervical tissue (p = 0.74). There was no difference in intra- and post-operative complications in the two groups. Positive endocervical resection margins (R0) were 9.9% in video exoscopy group and 8.7% in colposcopy group, respectively. Unclear endocervical resection margins (Rx) were 2.0% in both groups. Mean total excised cervical volume was 1.20 cubic centimeter (cc 3) in group A, and 1.24 cc3 in group B, respectively. Recurrent disease occurred in 2.3% of patients at 6 months follow-up. Conclusion: Magnification assisted loop excision of CIN 2+ is equally effective and safe under colposcopic and video exoscopy guidance. The latter technique could potentially offer an alternative treatment of CIN 2+ lesions for doctors unfamiliar with colposcope. © Springer-Verlag 2013.

Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (T1) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done respectively, followed by endocervical curettage. Volume of removed tissue, complications, and positive resection margins were compared for the colposcopy and the VITOM groups. Findings: Demographic and reproductive features were similar between groups. In the VITOM group 49% of patients had zone T1, 30% had zone T2, and 21% had zone T3. In the group of patients managed by colposcopy, 48, 45, and 7% of patients had zone T1, T2 and T3 zone, respectively (p0.05). There were no significant differences in the type of procedure or the mean volume of removed tissue. Results were similar for both groups with respect to positive resection margins and complications. Conclusion: VITOM is a safe and reliable system. Results using the VITOM system are comparable to those obtained with conventional colposcopy. The potential advantage of VITOM is the broader availability of endoscopic systems in the operating theatre. © Georg Thieme Verlag KG Stuttgart · New York.

Purpose: Our aim is to study the feasibility and effect of bilateral laparoscopic temporary occlusion of uterine arteries by special vascular clamps on blood loss during laparoscopic myomectomy. Methods: Of 166 women with symptomatic uterine myomas necessitating surgical intervention who wished to retain their uteri, 80 underwent laparoscopic uterine artery clipping and myomectomy (experimental group) and 86 received laparoscopic myomectomy only (control group). Main outcome measures were operating time, number and weight of leiomyomas, blood loss, Doppler examination of the uterine arteries and complications of procedure. Results: In the experimental group the median hemoglobin drop measured on day 3 postoperatively was 1.2 g/dl. In the control group the mean hemoglobin drop measured on day 3 postoperatively was 1.45 g/dl. The time needed to put the clips in place (the time from the opening of the retroperitoneum and the positioning of the clips) varied between 6 and 40 min. No patient required blood transfusion. There were no conspicuous complications. Conclusion: The use of the clips has proved to be statistically effective in reducing hemoglobin loss during laparoscopic myomectomy. © 2012 Springer-Verlag.

Presented is a case report of laparoscopic repair of an external iliac artery injury using titanium Yasargil clamps and intracorporeal suture during lymphadenectomy. Yasargil clamps were introduced and placed, 1 distal and 1 proximal to the lesion. The vascular injury site was identified and repaired using intracorporeal sutures. Laparoscopic staging was completed successfully. No sign of thrombosis or vascular occlusion was detected. The patient was discharged on postoperative day 4 to receive adjuvant therapy. Laparotomy is the accepted way of managing major vascular injuries during laparoscopy. However, in controlled circumstances, with availability of Yasargil clamps and a surgeon experienced with intracorporeal suturing, immediate laparoscopic repair of major vascular injury is feasible and is a safe alternative to open surgical repair. © 2011 AAGL.

- Abstract
Objective: Gynecological malignancies are significant causes of mortality and morbidity in women worldwide. Although surgery is an important treatment method, both the extent of the surgery and the factors related to the patient affect postoperative processes. The National Early Warning Score 2 (NEWS2) is a simple, inexpensive, and safe early warning score developed in 2012 and updated in 2017. Although it is not commonly used in surgical patients, its use in patients who will undergo major surgery may provide insights about the postoperative process. This study investigates the importance of NEWS2 and its relationship in patients with for major gynecologic oncology surgery., Materials and Methods: Forty-four patients with gynecologic malignancies scheduled for major abdominal surgery were included in this study. Patients with a NEWS-2 score of <3 were included in group 1, and patients with a NEWS-2 score of more than 3 were included in groups 2. NEWS2 Score, Sequential Organ Failure Assessment (SOFA), and Acute Physiology and Chronic Health Evaluation 2 scores (APACHE 2) were calculated. In addition, postoperative routine clinical and laboratory parameters were evaluated. Operation time, duration of intubation in the intensive care unit (ICU), the length of the intensive care stay, and length of hospitalization were recorded., Results: Duration of intubation in the ICU in group 1 with a NEWS2 <3 [8.2 (0-18) vs 16.2 (3-39), respectively; p<0.01], ICU length of stay [21.6 (4-27) vs 47.3 (4-113), respectively; p<0.01], length of hospitalization [11.6 (5-56) vs 18.6 (8-67), respectively; p<0.01]. NEWS2 >3 was significantly higher compared to group 2. The SOFA score was significantly higher in group 2 compared with group 1 [1.2±0.5 vs 4.1±1.9; respectively; p<0.01]. In the correlation analysis, the NEWS2 score level was positively correlated with the SOFA score (p<0.001, r=0.81) and hospitalization time (p<0.001, r=0.60) and neutrophil lymphocyte ratio (NLR) (p<0.001, r=0.47)., Conclusion: These findings suggest that the NEWS2 score may be correlated with the length of intensive care intubation, length of intensive care stay, and length of hospitalization. NEWS2 is an effective and simple scoring system that provides information about postoperative outcomes in gynecologic oncology patients scheduled for major surgery.

- Abstract
Background: The current approach to endometrial cancer screening requires that all patients be able to recognize symptoms, report them, and carry out appropriate interventions. The current approach to endometrial cancer screening could become a problem in the future, especially for Black women and women from minority groups, and could lead to disparities in receiving proper care. Moreover, there is a lack of literature on artificial intelligence in the prediction and diagnosis of endometrial intraepithelial neoplasia and endometrial cancer., Objective: This study analyzed different artificial intelligence methods to help in clinical decision-making and the prediction of endometrial intraepithelial neoplasia and endometrial cancer risks in pre- and postmenopausal women. This study aimed to investigate whether artificial intelligence may help to overcome the challenges that statistical and diagnostic tests could not., Study Design: This study included 564 patients. The features that were collected included age, menopause status, premenopausal abnormal bleeding and postmenopausal bleeding, obesity, hypertension, diabetes mellitus, smoking, endometrial thickness, and history of breast cancer. Endometrial sampling was performed on all women with postmenopausal bleeding and asymptomatic postmenopausal women with an endometrial thickness of at least 3 mm. Endometrial biopsy was performed on premenopausal women with abnormal uterine bleeding and asymptomatic premenopausal women with suspected endometrial lesions. Python was used to model machine learning algorithms. Random forest, logistic regression, multilayer perceptron, Catboost, Xgboost, and Naive Bayes methods were used for classification. The synthetic minority oversampling technique was used to correct the class imbalance in the training sets. In addition, tuning and boosting were used to increase the performance of the models with a 5-fold cross-validation approach using a training set. Accuracy, sensitivity, specificity, positive predictive value, and F1 score were calculated., Results: The prevalence of endometrial or preuterine cancer was 7.9%. Data from 451 patients were randomly assigned to the training group, and data from another 113 patients were used for internal validation. Of note, 3 of 9 features were selected by the Boruta algorithm for use in the final modeling. Age, body mass index, and endometrial thickness were all associated with a high risk of developing precancerous and cancerous diseases, after fine-tuning for the multilayer computer to have the highest area below the receiver operating characteristic curve (area under the curve, 0.938) to predict a precancerous disease. The accuracy was 0.94 for predicting a precancerous disease. Precision, recall, and F1 scores for the test group were 0.71, 0.50, and 0.59, respectively., Conclusion: Our study found that artificial intelligence can be used to identify women at risk of endometrial intraepithelial neoplasia and endometrial cancer. The model is not contingent on menopausal status or symptoms. This may be an advantage over the traditional methodology because many women, especially Black women and women from minority groups, could not recognize them. We have proposed to include patients to provide age and body mass index, and measurement of endometrial thickness by either sonography or artificial intelligence may help improve healthcare for women in rural or minority communities., (© 2023 The Authors.)

Background: New methods to reduce subjectivity in preoperative magnetic resonance imaging (MRI) staging of endometrial cancer are needed., Purpose: To investigate the role of MRI quantitative assessment in staging and risk stratification of endometrial cancer., Material and Methods: Preoperative T2-weighted (T2W) images and diffusion-weighted imaging of 42 patients were analyzed retrospectively by two radiologists. Tumor area ratio (TAR) and tumor volume ratio (TVRseg) were calculated by semi-automatic segmentation of the tumor and uterus on T2W imaging and apparent diffusion coefficient (ADC). TVR was also calculated by the 3D metric method (TVRmetric). Mean ADC
tumor was calculated. The patients were allocated to risk groups regarding the stage, grade, and lymphovascular invasion (LVI) status., Results: TAR, TVRmetric, T2W TVRseg, and ADC TVRseg showed a significant difference between the superficial and deep myometrial invasion groups ( P < 0.001). All of these parameters showed a good diagnostic performance for detecting deep myometrial invasion (AUC>0.82), the highest accuracy rate (85%) was found with T2W TVRseg. LVI was significantly associated with TAR ( P = 0.002) and T2W TVRseg ( P = 0.014), while the cervical invasion was associated with TAR ( P = 0.03). ADCtumor was significantly lower in high-grade tumors ( P = 0.002). There was a significant difference in ADCtumor ( P = 0.002), TAR ( P = 0.004), and T2W TVRseg ( P = 0.038) between the low- and high-risk groups. AUC of TAR and T2W TVRseg for detecting high-risk groups were 0.80 and 0.77, respectively, while AUC of ADCtumor for the low-risk group was 0.75., Conclusion: MRI quantitative assessments such as TAR, TVR, and ADCtumor may improve the accuracy of preoperative staging and can help in risk stratification of endometrial cancer.- Published

- Abstract
Background: Screening of the nutrition status is recommended for the early detection and treatment of cancer-associated malnutrition to improve the prognosis. We aimed to compare the prognostic value of Patient Generated-Subjective Global Assessment (PG-SGA) and CT measured sarcopenia in patients with gynecological cancer., Methods: A total of 107 patients of which were 57 endometrial, 37 ovarian, and 13 cervical cancer who underwent surgery and evaluated by PG-SGA were enrolled. Skeletal muscle index (SMI) was calculated by automatic segmentation of the muscle area at the L3 level on abdominal CT scan and defined by the cut-off value of 38.9 cm
2 /m2 . Karnofsky and Eastern Cooperative Oncology Group (ECOG) Performance Status scorings were performed. Hospitalization length (HL), overall- (OS), and progression-free- survival (PFS) were analyzed. Body muscle index (BMI) (kg/m2 ) was calculated. Serum CA-125 and albumin levels were obtained., Results: The prevalence of malnutrition and sarcopenia were 67% and 26.2%, respectively. BMI was significantly associated with PG-SGA (p = 0.02) and SMI (p = 0.01). PG-SGA significantly correlated with CA-125 (r = 0.33, p = 0.002), ECOG (r = 0.29, p = 0.002), Karnofsky (r = -0.34, p < 0.001), and HL (r = 0.27, p = 0.004). PG-SGA showed a significant association with PFS (p = 0.007) and OS (p = 0.001). PG-SGA≥9 showed a significant relationship with prolonged HL, mortality, and progression (OR = 1.08; p = 0.03, OR = 23.09; p = 0.003, and OR = 5.39; p = 0.001, respectively)., Conclusion: PG-SGA can identify patients at nutritional risk earlier than SMI. PG-SGA shows a higher correlation with HL and clinical performance scores than SMI. PG-SGA is a better prognostic factor for prolonged HL, OS, and PFS., Competing Interests: Declaration of competing interest None declared., (Copyright © 2022 European Society for Clinical Nutrition and Metabolism.

- Abstract
Small molecule inhibitors have previously been investigated in different studies as possible therapeutics in the treatment of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In the current drug repurposing study, we identified the leukotriene (D4) receptor antagonist montelukast as a novel agent that simultaneously targets two important drug targets of SARS-CoV-2. We initially demonstrated the dual inhibition profile of montelukast through multiscale molecular modeling studies. Next, we characterized its effect on both targets by different in vitro experiments including the enzyme (main protease) inhibition-based assay, surface plasmon resonance (SPR) spectroscopy, pseudovirus neutralization on HEK293T/hACE2+TMPRSS2, and virus neutralization assay using xCELLigence MP real-time cell analyzer. Our integrated in silico and in vitro results confirmed the dual potential effect of montelukast both on the main protease enzyme inhibition and virus entry into the host cell (spike/ACE2). The virus neutralization assay results showed that SARS-CoV-2 virus activity was delayed with montelukast for 20 h on the infected cells. The rapid use of new small molecules in the pandemic is very important today. Montelukast, whose pharmacokinetic and pharmacodynamic properties are very well characterized and has been widely used in the treatment of asthma since 1998, should urgently be completed in clinical phase studies and, if its effect is proved in clinical phase studies, it should be used against coronavirus disease 2019 (COVID-19)., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2021 The American Society of Gene and Cell Therapy.

- Abstract
The COVID-19 pandemic has resulted in 198 million reported infections and more than 4 million deaths as of July 2021 (covid19.who.int). Research to identify effective therapies for COVID-19 includes: (1) designing a vaccine as future protection; (2) de novo drug discovery; and (3) identifying existing drugs to repurpose them as effective and immediate treatments. To assist in drug repurposing and design, we determine two apo structures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease at ambient temperature by serial femtosecond X-ray crystallography. We employ detailed molecular simulations of selected known main protease inhibitors with the structures and compare binding modes and energies. The combined structural and molecular modeling studies not only reveal the dynamics of small molecules targeting the main protease but also provide invaluable opportunities for drug repurposing and structure-based drug design strategies against SARS-CoV-2., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2021 The Authors.

- Abstract
Study Objective: To present technique of vaginally assisted laparoscopic urethrolysis and mesh excision after tension-free vaginal tape., Design: Demonstration video., Setting: Despite the Food and Drug Administration's warning to limit the use of mesh, midurethral sling surgery (MUS) has not significantly decreased, but operations for complications have increased 3 times [1]. Urethral obstruction after MUS has an incidence of 2.7% to 11% [2] that requires resurgery, which ranges from pull-down, mesh excision to urethrolysis and is chosen by the surgeon's experience. Retropubic urethrolysis and mesh excision are reported to be more successful [3]. Urethrolysis can be performed by a retropubic, transvaginal, or suprameatal approach. Transvaginal mesh excision and urethrolysis are not satisfactory in all cases, and it might be difficult to identify the mesh if it is dislocated proximally or buried in dense fibrosis, which may increase urethral/bladder injuries. Although vaginal urethrolysis and mesh removal are usually preferred as the primary approach, there is no randomized controlled trial comparing retropubic and vaginal urethrolysis with/without mesh removal. Gynecologists should master each technique to provide individualized treatment. Laparoscopic urethrolysis has the advantage of the identification of neighboring structures and provides a safer operation (Fig. 1). Combined vaginal and laparoscopic approaches can be used to totally remove the mesh and for difficult surgeries at the junction of the retropubic urethra and the midurethra (Fig. 2)., Interventions: (1) Timing of urethrolysis is controversial. Although urethral loosening or pulling down in the first few days and mesh excision in the first 15 days can be useful, urethrolysis can be chosen for delayed cases with marked fibrosis. Preoperative diagnostic cystoscopy to exclude urethral mesh erosion is essential. Intermittent catheterization until surgery should be done. (2) The technique is described in 5 steps. The arcus tendineus is an important landmark [4] (Fig. 3)., Conclusion: Laparoscopic urethrolysis for urinary obstruction after MUS can be a safe and successful procedure after failed vaginal approach or can be considered as a primary approach in select cases., (Copyright © 2021 AAGL.

- Abstract
Objective: Surgical staging is the most confidential method for prognosis prediction. However, in which stage the surgery is needed and the treatment management of these patients is controversial. Presentation of new determinant factors with imaging methods for prediction of poor prognosis can provide better disease management. The aim of our study was to demonstrate the ability of metabolic tumor volume and total lesion glycolysis as a prognostic factor to predict the disease-free survival time, necessity of adjuvant radiotherapy-chemotherapy, and the association of these parameters with the clinicopathological features., Methods: Forty-four endometrial cancer diagnosed patients whose PET/CT scans were performed for treatment planning were included in our study. Metabolic parameters (SUVmax, metabolic tumor volume, total lesion glycolysis) of the primary tumor were calculated. Abdominal hysterectomy was performed for all patients. Histopathologic findings were noted. Patients were followed for 31.4 ± 14.8 months., Results: Metabolic tumor volume and total lesion glycolysis were significant prognostic factors for disease-free survival, whereas SUVmax did not effect disease-free survival. According to regression analysis, only metabolic tumor volume was found significant for radiotherapy planning (cutoff metabolic tumor volume; 26.30 ml). There was significant association between metabolic tumor volume, total lesion glycolysis and early-stage, myometrial invasion, and lymph node positivity. We observed only weak association between SUVmax and myometrial invasion. ROC curve calculated metabolic tumor volume and total lesion glycolysis cutoff values as 19.6 ml and 90 g for early-stage, 14.3 ml and 173.4 g for myometrial invasion, and 29.7 ml and 283.1 g for lymph node positivity, respectively., Conclusion: Metabolic tumor volume and total lesion glycolysis may be used as prognostic factors for endometrial cancer. The association between SUVmax and clinical findings, disease-free survival, histopathological features are weak. Further studies are needed for demonstrating the prognostic value of metabolic volumetric parameters.

- Abstract
Objectives: The more surgical effort and performing extensive upper abdominal surgery (UAS) are often required to accomplish the highest rates of optimally cytoreduction in patients with ovarian cancer. Nonetheless, the rate of complications increases with extensive surgery. We have studied the upper abdominal surgery complications by Clavien-Dindo Classification (CDC) and analyzed parameters affecting post-operative severe complications classified through Clavien-Dindo., Material and Methods: A retrospective cohort of patients diagnosed with epithelial ovarian cancer from January 1st 2009 to April 30th 2016 was evaluated. Patients who underwent at least one UAS procedure with or without optimal cytoreduction for epithelial ovarian cancer (stage IIIC-IV or recurrent) were included. Postoperative complications were recorded according to the Clavien-Dindo Classification., Results: In total, 58 patients were included. There were 120 UAS procedures performed on the 58 patients. Diaphragm peritonectomy was the most performed surgery (50%, 29/58), and then the other UAS procedures were liver surgery (39.7%, 23/58), cholecystectomy (24.1%, 14/58), splenic surgery (24.1%, 14/58), full-thickness diaphragm resection (22.4%, 13/58), pancreatic surgery (19%, 11/58), resection of tumor from porta hepatis (17.2%, 10/58), celiac lymph node excision (8.6%, 5/58), partial gastrectomy (1.7%, 1/58), respectively. Thirteen patients (22.4%) had post-operative grade 3-5 complications according to CDC within 30 days after surgery., Conclusions: This current study demonstrated that the addition of extensive upper abdominal surgery procedures were not associated with increased postoperative severe complications in patients with recurrent or advanced ovarian cancer. These procedures are safe and feasible for patients in need and also can be performed with acceptable mortality and morbidity.

- Abstract
The present study aimed to examine hypoxia-inducible factor (HIF)-1α expression and its association with glucose uptake in invasive breast cancer. In addition, connections between glucose uptake and several other prognostic parameters of breast cancer were studied. Between August 2013 and April 2015, 92 patients with biopsy-diagnosed breast cancer were subjected to
18 F-fluorodeoxyglucose positron emission tomography/computed tomography. The primary tumor and nodal maximum standardized uptake values (SUVmax) were recorded, and HIF-1α expression and clinical parameters, including tumor mass, estrogen receptor (ER) and progesterone receptor (PgR) levels, human epidermal growth factor receptor-2 (HER-2), Ki-67 index, grade and histology, were analyzed. SUVmax was compared with clinicopathological parameters and HIF-1α expression. The median SUVmax values of the ER-negative and PgR-negative tumors were significantly increased compared with ER and PgR-positive tumors, respectively (P=0.004 and P=0.008). SUVmax differed significantly between the T2 and T3 tumors and the T1 tumors. The median SUVmax levels were higher in the Ki-67 expression >10% group than the Ki-67 index <10% group (P=0.001). Although the median SUVmax values in HER-2-positive and -negative tumors were similar, triple-negative tumors demonstrated significantly higher values (P=0.04). With regard to tumor grade, the median SUVmax was greater in the high-grade tumors compared with the low-grade tumors. SUVmax did not exhibit a significant correlation with HIF-1α expression; however, HIF-1α expression was associated with tumor size and PgR expression. HIF-1α expression increased with a larger tumor size (r=0.27; P=0.008) and decreased PgR expression (r=-0.26; P=0.0002). The axillary nodal SUVmax of the N1 tumors was significantly lower than the N2 and N3 tumors (P<0.0001). In the multivariate analysis, tumor size, Ki-67 expression and ER Allred score were independent factors that impacted SUVmax. The results of the present study indicated strong associations between tumor size, tumor grade, Ki-67 expression, triple-negativity, downregulated hormone receptor expression and SUVmax values. Conversely, there was no association observed between glucose uptake and levels of HIF-1α. Based on these results, it is suggested that the lack of assiocation between hypoxia and glucose uptake indicates phenotypic independence.- Published

- Abstract
Objective: To study the relation between SUVmax, hypoxia inducible factor 1α (HIF-1α), angiogenetic factor adrenomedullin (AM) and antiapoptotic factor Bcl-2 in endometrial cancer., Subjects and Methods: Thirthy eight patients who were diagnosed after a preoperative endometrial biopsy with endometrium cancer underwent pre-operative positron emission tomography/computed tomography (PET/CT) utilizing fluorine-18-fluorodeoxy glucose (¹⁸F-FDG). Maximum standardized uptake values (SUVmax) of the primary tumor were measured. After hysterectomy and bilateral salpingo-oophorectomy, microscopic slides of the 38 endometrial adenocarcinoma patients were evaluated by a surgical pathologist to confirm the diagnosis. Immunohistochemical staining for AM, Bcl-2 and HIF-1α was studied., Results: In all patients, ¹⁸F-FDG uptake was detected. The mean SUVmax of the tumors was 11.8 ± 5.9. Although SUVmax was higher in HIF-1α positive tumors, this finding was not statistically important. No correlation was found between SUVmax and HIF-1α positivity. Mean SUVmax was 6.4 ± 3 and 12.3 ± 1.4 in AM negative and AM positive patients, respectively. Mean SUVmax was 10.6 ± 4.9 and 12.3 ± 1.4 in Bcl-2 negative and Bcl-2 positive patients, respectively. We found no correlation between SUVmax, AM or Bcl-2 expression. Allred scores were not related with SUVmax in regression analysis., Conclusion: Our study in a small number of patients is the first to show that SUVmax, although expected is not associated with HIF-1α, AM or with Bcl-2 in endometrial cancer. Increased uptake of ¹⁸F-FDG in endometrial cancer seems to be independent of HIF-1α and its downstream factors.

Objective: Pre-operative imaging characteristics of placental site trophoblastic tumor (PSTT) are variable and non-specific. Although magnetic resonance imaging (MRI), ultrasonography, chest CT and X-rays findings have been studied the fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) findings of PSTT have not been previously documented. We present the findings of a first case of PSTT evaluated by pre-operative ¹⁸F-FDG PET/CT. A suspicious mass was biopsied and revealed PSTT in post-operative pathological examination. She was referred to the gynecology-oncology department. The ¹⁸F-FDG PET/CT scan revealed a 27 x 20 mm laterally expanded lesion that showed increased ¹⁸F-FDG uptake (SUVmax: 5.20) on the right isthmus of the uterus. The ¹⁸F-FDG PET/CT findings were in accordance with those from chest X-ray/s, CT and pelvic ultrasonography. A systematic, nerve sparing, paraaortic and pelvic lymph node dissection along with total hysterectomy and salpingoopherectomy was performed. The patient was discharged uneventfully., Conclusion: ¹⁸F-FDG PET/CT scan was able to identify the mass in the uterus which was shown by pathology to be PSTT. This finding of PET/CT was in accordance with other imaging techniques. Lymphatic mapping of ¹⁸F-FDG PET/CT in this case was also in accordance with surgery and pathology findings.

- Abstract
Objectives: The aim of the present study is to evaluate mental workload and fatigue in fingers, hand, arm, shoulder in single-incision laparoscopic surgery (SILS) and multiport laparoscopy., Methods: Volunteers performed chosen tasks by standard laparoscopy and SILS. Time to complete tasks and finger and hand strength were evaluated. Lateral, tripod, and pulp pinch strengths were measured. Hand dexterity was determined by pegboard. Electromyography recordings were taken from biceps and deltoid muscles of both extremities. The main outcome measurement was median frequency (MF) slope. NASA-TLX was used for mental workload., Results: Time to complete laparoscopic tasks were longer in the SILS group (P < .05). Decrease of strength in fingers and hand were similar in SILS and standard laparoscopy. Pegboard time was increased in both hands after SILS (P < .05). MF slope of biceps muscle and deltoid muscle in SILS was far away from the reference slope. MF slope of biceps muscle and deltoid muscle in standard laparoscopy was close to reference slope, indicating there was more fatigue in biceps and deltoid muscles of both upper extremities in SILS group. NASA-TLX score was 73 ± 13.3 and 42 ± 19.5 in SILS and multiport laparoscopy, respectively (P < .01). Mental demand, physical demand, temporal demand, performance, effort, and frustration were, respectively, scored 10.7 ± 3.8, 11.7 ± 3.5, 12.2 ± 2.7, 11 ± 3, 13.6 ± 2.7, and 13.5 ± 2.8 in SILS and 6.3 ± 3.1, 6.6 ± 3.3, 7.3 ± 3.3, 7.1 ± 4.1, 7.9 ± 3.9, and 6.6 ± 3.8 in standard laparoscopy (P < .01)., Conclusions: SILS is mentally and physically demanding, particularly on arms and shoulders. Fatigue of big muscles, effort, and frustration were major challenges of SILS. Ergonomic intervention of instruments are needed to decrease mental and physical workload., (© The Author(s) 2014.)

Purpose: To discuss what features of colposcopy should be developed for the future in different settings., Result: There are cons and pros of aiming sensitivity, negative predictive value and specificity and positive predictive value. In case of diagnosis and intervention, methods increasing the specificity and positive predictive value will help to decrease unnecessary interventions. Besides, HPV test is highly sensitive and has a good negative predictive value. It is usually available before colposcopy., Conclusion: Colposcopy can be used in a screening or diagnostic/interventional scenario. Aims to improve sensitivity or specificity may change according to the aim of colposcopy. However, in the presence of highly sensitive tests which are performed before colposcopy, first goal to improve for colposcopy can be specificity and positive predictive value.

Purpose: To evaluate the clinical value of four objective colposcopic criteria inner border, ridge sign, cuffed crypt openings and rag sign to diagnose cervical intraepithelial neoplasia grade 2 or worse (CIN 2+), using video exoscopy and to compare it to subjective graduating signs., Methods: Retrospective evaluation of video recordings of 444 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and if indicated loop excisions. Most severe histological diagnosis was recorded. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and likelihood ratios (LR) with 95% confidence interval, for CIN 2+ were calculated., Results: Single biopsy, two biopsies and magnification-guided loop excision were performed in 60.8, 39.2 and 70.5% of patients, respectively. Sensitivity, specificity, PPV and NPV to detect CIN 2+ were 19.3, 99.2, 98.3 and 35.8%, for inner border sign; 53.1, 93.5, 94.7 and 47.6%, for ridge sign; 51.5, 84.9, 88.2, and 44.3%, for cuffed crypt openings, and 40.7, 96.4, 96.1 and 42.5%, for rag sign, respectively. The positive likelihood ratio (LR+) was 26.7 and the negative likelihood ratio (LR-) was 0.81, for inner border sign; 8.2 and 0.5, for ridge sign; 3.41 and 0.57 for cuffed crypt openings; and 11.3 and 0.62 for rag sign, respectively. 90% of CIN 2+ had at least one objective sign. Combination of any two objective signs significantly increased the LR of the presence of CIN 2+, and was clinically superior to any combination of graduating signs., Conclusion: Objective colposcopic criteria are clinically useful and significantly associated with CIN 2+.

- Abstract
Purpose: To compare loop excisions of cervical intraepithelial neoplasia grade 2 or worse (CIN 2+) under video exoscopy, or colposcopic guidance, with respect to safety and effectiveness., Methods: Prospective multicentric randomized trial of 300 patients, undergoing loop excision for CIN 2+ either under video exoscopy (group A) or colposcope (group B) guidance. Intra- and post-operative complications, resection margins, and removed cervical volume in both groups were evaluated., Results: 19.3 % of patients in video exoscopy group and 15.5 % in colposcopy group (p = 0.67) had transformation zone (TZ) 3. 45/151 (29.8 %) of group A patients and 48/149 (32.2 %) of group B patients underwent top-hat procedure, i.e., one superficial excision followed by one deeper removal of the endocervical tissue (p = 0.74). There was no difference in intra- and post-operative complications in the two groups. Positive endocervical resection margins (R0) were 9.9 % in video exoscopy group and 8.7 % in colposcopy group, respectively. Unclear endocervical resection margins (Rx) were 2.0 % in both groups. Mean total excised cervical volume was 1.20 cubic centimeter (cc³) in group A, and 1.24 cc³ in group B, respectively. Recurrent disease occurred in 2.3 % of patients at 6 months follow-up., Conclusion: Magnification assisted loop excision of CIN 2+ is equally effective and safe under colposcopic and video exoscopy guidance. The latter technique could potentially offer an alternative treatment of CIN 2+ lesions for doctors unfamiliar with colposcope.

- Abstract
Objective: Individualized treatment of pregnant patients with cervical cancer is mandatory; hence, information on nodal status is pivotal to allow a waiting strategy in early-stage disease.We aimed to verify the oncological safety and surgical reproducibility of a standardized laparoscopic pelvic lymphadenectomy in pregnant patients with cervical cancer., Methods: We standardized laparoscopic pelvic lymphadenectomy during the first and second term of gestation in 32 patients with cervical cancer since 1999. According to gestational week (GW) of less than 16 GWs or more than 16 GWs, 2 different techniques were used., Results: The International Federation of Gynecology and Obstetrics stages were IA in 10 patients, IB1 in 17 patients, IB2 in 4 patients, and IIA in 1 patient. Mean (SD) GW was 17.5 (5.1) weeks. Mean (SD) operative time was 105.4 (29) minutes. Mean (SD) blood loss was 5.3 (10.2) mL. There were no conversion to laparotomy and no intraoperative complications. A median number of 14 pelvic lymph nodes (range, 8-57) were harvested. Median hospital stay was 6 days. Median follow-up is 42.5 months (range, 17-164). Four patients had lymph node metastases. Five patients interrupted their pregnancy. Fourteen patients were given neoadjuvant platin-based systemic therapy. All patients are alive and disease free. All children born through cesarean delivery at a mean (SD) 34 (1.9) GWs are well and show normal clinical neurological development., Conclusions: To the best of our knowledge, this is the largest series so far reported on laparoscopic pelvic lymphadenectomy during pregnancy. This procedure is safe and associated with good oncological and obstetrical outcomes.
