Lymphadenectomy, obesity and open surgery are associated with surgical complications in endometrial cancer

To investigate surgical complications related to the staging procedure for endometrial cancer (EC) and to explore complication associations towards patient characteristics and survival. A population-based cohort study of women diagnosed with EC where primary surgery was performed at a tertiary centre between 2012 and 2016. The Swedish Quality Registry for Gynecological Cancer was used for identification, medical records reviewed and surgical outcomes, including complications according to Clavien-Dindo (CD), and comorbidity (Charlson's index) registered. Uni- and multivariable logistic regression analyses were performed with complications as outcome and multivariable Cox regression analysis with overall survival (OS) as endpoint. In total 549 women were identified where 108 (19.7%) had CD grade II-V complications. In the multivariable regression analysis; surgical technique, BMI and lymph node dissection, but not comorbidity or age, were found to be risk factors for complications CD grade II-V, with OR of 0.32 (95%CI:0.18-0.56) for minimalinvasive surgery (MIS) compared to open, OR 2.18 (95%CI:1.37-3.49) for BMI ≥30 and OR 2.63 (95%CI:1.32-5.31) for pelvic and paraaortic lymphnode dissection. In Cox regression analysis, a significant lower OS was found within the first 1.5 years for the cohort of complications (CD II-V) compared to no complications. Surgical staging with lymphadenectomy was found a risk factor for complications together with high BMI in EC. Using MIS was significantly associated with less complications. Overall survival was found to be negatively affected within the first years after complications. Our results may be taken into consideration when performing updated treatment guidelines including surgical staging.

Colposcopic assessment by Swedescore, evaluation of effectiveness in the Swedish screening programme: a cross‐sectional study

AbstractObjectiveTo evaluate the effectiveness and performance of Swedescore in the Swedish screening programme.DesignCross‐sectional register study.Setting and PopulationAll Swedish women aged over 18 years with a colposcopic assessment linked to a biopsy in the Swedish National Cervical Screening Registry, 2015–20.MethodsColposcopies with Swedescore were compared with the histopathological diagnosis of cervical intraepithelial neoplasia grade 2 or higher (CIN2+). The respective influence of cytology and human papillomavirus (HPV) testing, at referral for colposcopy and concurrently with colposcopy, were investigated in regression models.Main Outcome MeasuresCIN2+.ResultsA total of 11 317 colposcopic assessments with Swedescore were included. Odds ratios for CIN2+ increased for every step in the Swedescore scale. At Swedescore ≥0–1, the proportion of CIN2+ was 9.8%. At Swedescore ≥8, the specificity was 93.3% and the positive predictive value was 60.1%, Area under the receiver operating characteristics curve (AUC) was 0.71. If the smear had been abnormal at referral, a normal colposcopy (Swedescore 0–1) was still associated with a CIN2+ risk of more than 5%. In the regression model, cytology and HPV had higher odds ratio for CIN2+ than colposcopy; the combination resulted in an AUC of 0.88.ConclusionsSwedescore works well in a routine clinical setting but colposcopy assessed with Swedescore was inferior to that reported in previous clinical studies. No safe cutoff level was identified for refraining from biopsy. See‐and‐treat at Swedescore 8–10 is feasible only if referral cytology showed high‐grade squamous intraepithelial lesion.Tweetable AbstractNo safe cutoff level for refraining from biopsy nor for see‐and‐treat with Swedescore.

Molecular Classification in Relation to Prevention of Endometrial Cancer Recurrence and Lifestyle Factors

Endometrial cancer (EC) is one of the most prevalent cancers in women worldwide with a significantly increasing incidence, especially in developed countries. One of the reasons for the increase in the incidence of this disease is the rising incidence of obesity as the biggest risk factor for the development of this disease. Other important risk factors are hypertension, diabetes mellitus and the general ageing of the population. These risk factors are not only associated with a higher risk of developing the disease, but also, for example, with post-operative complications affecting the quality of life of patients after surgery. The molecular classification of endometrial cancer, which has been introduced into clinical practice in recent years, is currently helping physicians to make treatment decisions for individual patients and predict prognosis. In this project, we would like to focus on the relationship of this molecular classification with genomic mutational signatures detected by whole-exome sequencing and their association with lifestyle risk factors for endometrial cancer (obesity - BMI, hypertension, diabetes mellitus), including the extent of staging lymphadenectomy. Identification and detailed analysis of dominant mutational profiles associated with a specific molecular subtype of EC and their influence on the presence of lifestyle risk factors may have a major impact on both disease development and prevention of disease recurrence. The possible relationship of the mutational profile with the extent of staging lymphadenectomy may help in deciding the extent of this surgical procedure, which subsequently affects the quality of life of patients, especially in patients with high BMI. Given the widespread prevalence of lifestyle risk factors in the developed world, a detailed understanding of the relationship between the genetic profile, its alterations and the prevalence of these risk factors, with potentially major implications for treatment success, is crutial.
