An early diagnosis and treatment of this condition could improve patients’ outcome. Aim of this study was to define the role of postoperative 18 F-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography ( 18 F-FDG-PET/CT) in patients with high risk of residual disease after EC surgery. Methods : Patients operated for EC, with one or more risk factors, who underwent 18 F-FDG-PET/CT before adjuvant treatment were included in this observational study. The primary endpoint was the rate of patients in whom 18 F-FDG-PET/CT changed the treatment strategy and/or the radiotherapy (RT) planning. Results : Our analysis included 58 patients (median age: 67.5 years, range: 48.0–86.0) with the following risk factors: lymphadenectomy not performed (26 patients; 44.8%), inadequate lymphadenectomy (23 patients; 39.7%), and high risk of residual disease due to advanced stage (nine patients; 15.5%). Postoperative 18 F-FDG-PET/CT imaging was positive in 18 patients (31%) in the following sites: pelvic extra-nodal disease (one patient), pelvic and/or paraaortic lymph nodes (12 patients), distant metastases (one patient), or combination of previous sites (four patients). Based on these results, the adjuvant therapeutic strategy was changed in five patients, three of whom were referred to chemotherapy alone due to distant metastases and two of whom were referred to nodal-directed treatment due to lymph node metastases (lymphadenectomy and pelvic chemoradiation plus boost, respectively). Furthermore, based on the 18 F-FDG-PET/CT results, the RT plan was modified in 13 patients (addition of a boost on residual pelvic/abdominal disease in 12 and target modification in one, respectively). Therefore, based on postoperative 18 F-FDG-PET/CT findings, the therapeutic strategy and the RT plan were changed in 5 patients (8.6%) and 13 patients (22.4%), respectively. Conclusion : In this analysis, the adjuvant treatment was modified after post-operative 18 F-FDG-PET/CT in about one third of patients. Further studies are needed to better define the risk factors (or their combinations) correlated with higher probability of residual disease after radical hysterectomy-adnexectomy for EC.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47107659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods : A systematic search of PubMed/MEDLINE, CINAHL, EMBASE, Web of Science, and PsycINFO databases from January 2000 through May 2020 included keywords related to research on educational programs for BCSs. Inclusion criteria included: (1) focus on an educational program for post-treatment breast cancer survivors; (2) original research; (3) peer-review journals; (4) English language; and (5) published between January 2000 to May 2020. EndNote X9 (software version: X9, manufacturer: Clarivate, website location: endnote.com) was used as the reference management software package to manage citations from search results. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) flowchart of the selection process is presented in this paper. Results : A total of 24 educational programs/interventions research studies include one mixed-method study, three qualitative studies, and twenty quantitative studies, were identified and analyzed. Three programs focused on BCSs’ self-management and self-efficacy, two programs focused on BCSs’ cognitive problems, seven programs focused on BCSs’ psychological distress, emotional support, and information seeking. In addition, one program focused on BCSs’ body image, body function, and sexual dysfunction issues, five programs focused on BCSs’ physical activities, nutritional levels, and normal body weight maintenance, two programs focused on BCSs’ supportive care and peer advocate support. Finally, one program focused on BCSs’ palliative care and end of life care, and three programs focused on BCSs’ post-treatment symptom clusters and overall quality of life. Conclusions : After breast cancer treatment ends, BCSs continue to suffer from long-term physical and psychological symptoms and report multiple unmet needs. Research on post-treatment breast cancer educational programs showed that programs assist BCSs with post-treatment symptom management and address their concerns while promoting supportive care and peer support to improve BCS’s overall quality of life. program.

Materials and methods : The study includes 127 cervical cancer patients diagnosed and treated at Akdeniz University Faculty of Medicine between January 2002 and December 2019. Data were collected retrospectively using the electronic archive system of the hospital. Patients with pathologically unknown tumor diameters were excluded from the study. Data were tested for normal distribution, and the mean, standard deviation, median, min-max values, and frequencies were used as descriptive statistics. Categorical data were expressed as numbers and percentages (%). The Student’s t -test, one of the parametric tests, was used to compare tumor diameters. Statistical Package for the Social Sciences (SPSS) 23 software (IBM Corp., Chicago, IL, USA) was used for data analysis. A p -value less than 0.05 was considered statistically significant in all tests. Results : The mean age of patients included in the study was 49.55 ± 11.67 years. Of all patients, 79.5% had a normal delivery. 87 (68%) of the patients were not using any contraceptive method, with 0.7%, condom protection was the least. Among the complaints of patients at admission, postcoital vaginal bleeding was the most common complaint with 42.5%, and asymptomatic patients were the second most common with 22%. Human papillomavirus (HPV) status was unknown in the vast majority of patients (91.3%). Regarding the stage status, stage 1b2 was the most frequently seen stage with 29 patients. Tumor histology revealed SCC in 80.3% and adenocarcinoma in 18.1%. The mean tumor diameter measured by transvaginal ultrasonography (TVS) was 3.30 ± 1.95, by magnetic resonance imaging (MRI) was 3.37 ± 2.03, and the pathologically measured tumor diameter was 3.17 ± 1.86. There was no statistically significant difference between the mean tumor diameter measured by TVS and MRI, MRI and pathology, and TVS and pathology ( p : 0.769, p : 0.589, p : 0.891, respectively). Conclusion : When used by specialists experienced in the field of gynecological oncology, ultrasonography can be considered as effective as MRI, especially in tumor size measurement in cervical cancer, due to its ease of use, cheapness, and easy accessibility in regions with low socioeconomic status.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47942549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes BRCA mutation screening patterns and results, demographics, clinical characteristics and the use of poly (ADP-ribose) polymerase inhibitors (PARPi) as maintenance treatment within a real-world sample of patients with advanced OC in the second-line (2L) treatment setting. Methods : Data were collected using the Adelphi Real World OC Disease Specific Programme (DSP)™, a point-in-time survey of physicians and their consulting patients with OC in clinical practice, undertaken across Europe (EU5: France, Germany, Italy, Spain and United Kingdom) and the United States (US) between December 2017–March 2018. Physicians completed a detailed patient record form for their next eight consecutively consulting patients, capturing data on their clinical history and treatment. All analysis was descriptive. Results : Of 1315 patients identified, 1096 (83%) were receiving 2L treatment and 219 (17%) were receiving 2L maintenance treatment; either PARPi (olaparib, rucaparib or niraparib, n = 103) or a non-PARPi (n = 116). BRCA screening rates varied between countries, increased with each line of therapy and were higher in the EU5 (55%) than the US (44%). 28% of patients receiving 2L treatment had a BRCA1/2 mutation. Patients receiving PARPi maintenance treatment had better Eastern Cooperative Oncology Group (ECOG) performance status, higher BRCA screening rates and higher proportions of serous epithelial OC than those receiving 2L treatment or non-PARPi maintenance. Common reasons for choosing 2L treatments were progression-free/overall survival benefit and improvement of quality of life. Conclusions : Despite guidelines recommending BRCA testing in patients with OC, many OC patients undergoing 2L treatment were not screened for BRCA mutations. Decisions related to PARPi use in 2L maintenance appeared to be driven by BRCA status, histology and response to first-line treatment.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46911422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key role of WEE1 kinase at this checkpoint makes inhibition of WEE1 kinase in combination with DNA damaging agents an attractive therapeutic strategy for HGSOC. Our aim was to characterise resistance mechanisms to WEE1 inhibitor AZD1775 and identify ways to overcome resistance ready for use in the clinic. Methods : AZD1775-resistant HGSOC cell clones were isolated and western blotting, cell cycle analysis, growth assays, RNA-Seq and gene expression analysis were used to characterise resistance mechanisms and investigate a way to overcome resistance. Results : A resistance mechanism previously reported in small cell lung cancer did not operate in HGSOC. Instead, resistance resulted from different cell cycle control pathway changes that slow AZD1775-induced cell cycle progression and reduce accumulation of replication associated DNA damage. One major change was reduced levels of CDK1, the substrate for WEE1 kinase inhibition; another was increased levels of PKMYT1, which can also inhibit CDK1. Increased expression of TGF β signalling to slow cell cycle progression occurred in resistant clones. A TGF β R1 inhibitor overcame resistance in a clone with the highest TGF β R1 receptor expression. Conclusions : Although overexpression of the membrane glycoprotein MDR1 is a common mechanism of drug resistance, it was not involved in our HGSOC cells. Instead AZD1775 resistance resulted from cell cycle control pathway changes that combine to slow AZD1775-induced cell cycle progression and so reduce accumulation of replication-associated DNA damage.","PeriodicalId":11903,"journal":{"name":"European journal of gynaecological oncology","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44865387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
