- Objective: Survival in cervical cancer has improved little over the last decades. We aimed to elucidate primary treatment patterns and survival. Methods: Population-based study of patients included in the Swedish Quality Registry for Gynecologic Cancer diagnosed 2011-2015. Main outcome was 5-year relative survival (RS). Age-standardised RS (AS-RS) was estimated for the total cohort and for the pooled study population of squamous, adenosquamous-, adenocarcinoma. Results: Median follow-up time was 4.6 years. The study population consisted of 2141 patients; 97% of the 2212 patients in the total cohort and the 5-year AS-RS was 71% and 70%, respectively. RS stage IB1: surgery alone 95% vs. 72% for definitive chemoradiotherapy (CT-RT) (p < 0.001). In stage IIA1 74% had CTRL, and 47% of operated patients received adjuvant (CT)-RT. RS stage IB2: surgically treated 81% (69% received adjuvant (CT)-RT) vs. 76% for (CT)-RT (p = 0.73). RS stage IIB: 77% for CT-RT + brachytherapy BT), 37% for RT + BT (p = 0.045) and 27% for RT-BT (p < 0.001). Stages III-IVA; <40% received CT-RT + BT, RS 45% vs. 18% for RT-BT (RR 4.1, p < 0.001). RS stage IVB 7%. Conclusion: Primary treatment of cervical cancer in Sweden adhered to evidence-based standard of care. Areas of improvement include optimising treatment for stages III-IVA, and avoiding combining surgery and radiotherapy. (C) 2019 Elsevier Inc. All rights reserved.

- Objective Design Correct preoperative identification of high-risk patients is important to optimise surgical treatment and improve survival. We wanted to explore if asparaginase-like protein 1 (ASRGL1) expression in curettage could predict lymph node metastases and poor outcome, potentially improving preoperative risk stratification. Multicentre study. Setting Population Ten hospitals in Norway, Sweden and Belgium. Women diagnosed with endometrial carcinoma. Methods Main outcome measures ASRGL1 expression in curettage specimens from 1144 women was determined by immunohistochemistry. ASRGL1 status related to disease-specific survival, lymph node status, preoperative imaging parameters and clinicopathological data. Results Conclusions ASRGL1 expression had independent prognostic value in multivariate survival analyses, both in the whole patient population (hazard ratio (HR) 1.63, 95% CI 1.11-2.37, P = 0.012) and in the low-risk curettage histology subgroup (HR 2.54, 95% CI 1.44-4.47, P = 0.001). Lymph node metastases were more frequent in women with low expression of ASRGL1 compared with women with high ASRGL1 levels (23% versus 10%, P < 0.001), and low ASRGL1 level was found to independently predict lymph node metastases (odds ratio 2.07, 95% CI 1.27-3.38, P = 0.003). Low expression of ASRGL1 in curettage independently predicts lymph node metastases and poor disease-specific survival.

Tidskriftsartikel (refereegranskat)abstract
- Background: Most endometrial carcinoma patients are diagnosed at an early stage with a good prognosis. However, a relatively low fraction with lethal disease constitutes a substantial number of patients due to the high incidence rate. Preoperative identification of patients with high risk and low risk for poor outcome is necessary to tailor treatment. Nucleotyping refers to characterization of cell nuclei by image cytometry, including the assessment of chromatin structure by nuclear texture analysis. This method is a strong prognostic marker in many cancers but has not been evaluated in preoperative curettage specimens from endometrial carcinoma. Methods: The prognostic impact of changes in chromatin structure quantified with Nucleotyping was evaluated in preoperative curettage specimens from 791 endometrial carcinoma patients prospectively included in the MoMaTEC multicenter trial. Results: Nucleotyping was an independent prognostic marker of disease-specific survival in preoperative curettage specimens among patients with Federation Internationale des Gynaecologistes et Obstetristes (FIGO) stage I-II disease (HR = 2.9; 95% CI, 1.2-6.5; P - 0.013) and significantly associated with age, FIGO stage, histologic type, histologic grade, myometrial infiltration, lymph node status, curettage histology type, and DNA ploidy. Conclusions: Nucleotyping in preoperative curettage specimens is an independent prognostic marker for disease-specific survival, with potential to supplement existing parameters for risk stratification to tailor treatment. Impact: This is the first study to evaluate the prognostic impact of Nucleotyping in curettage specimens from endometrial carcinoma and shows that this may be a clinically useful prognostic marker in endometrial cancer. External validation is warranted. (C) 2016 AACR.

- This chapter provides details on surgical preparations of the recipient before uterus transplantation. In both deceased and live donor uterus transplantation, the recipient should be surgically prepared so that the uterus can be brought into the pelvis of the recipient, as soon as the graft is prepared at the back-table. A synchronized preparation of the recipient will minimize the cold ischemic time of the organ. In our experience, the surgical preparation of a typical recipient takes about 1 h. This preparation is from first skin incision until all tissues are dissected, cleared, and with fixation sutures placed. In a live donor situation, the surgery of the recipient can start around 0.5 h before predicted vascular clamping with subsequent retrieval of the uterus. The recipient surgery will include sub-umbilical midline incision, dissection of the vaginal vault to free the top of the vagina from the bladder and the rectum, bilateral dissections to clear external iliac artery and vein, and bilateral placements of sutures for subsequent uterine fixation. In patients with the Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, there will be rudimentary uterine-like tissue above the vaginal vault and that tissue has to be cleaved to reach the top of the vagina. In patients with a present but nonfunctioning uterus or a cervical stump, total hysterectomy or cervical excision is included in the preparation procedure. A surgically well-prepared pelvic region of the recipient will increase the chance of a successful uterus transplantation procedure by facilitating short durations of warm ischemia and well-controlled surgery. © Springer Nature Switzerland AG 2020.

- Background: Preoperative risk stratification is essential in tailoring endometrial cancer treatment, and biomarkers predicting lymph node metastasis and aggressive disease are aspired in clinical practice. DNA ploidy assessment in hysterectomy specimens is a well-established prognostic marker. DNA ploidy assessment in preoperative curettage specimens is less studied, and in particular in relation to the occurrence of lymph node metastasis. Methods: Curettage image cytometry DNA ploidy in relation to established clinicopathological variables and outcome was investigated in 785 endometrial carcinoma patients prospectively included in the MoMaTEC multicentre trial. Results: Diploid curettage status was found in 72.0%, whereas 28.0% were non-diploid. Non-diploid status significantly correlated with traditional aggressive postoperative clinicopathological features, and was an independent predictor of lymph node metastasis among FIGO stage I-III patients in multivariate analysis (OR 1.94, P = 0.033). Non-diploid status was related to shorter disease-specific survival (5-year DSS of 74.4% vs 88.8% for diploid curettage, P<0.001). When stratifying by FIGO stage and lymph node status, the prognostic effect remained. However, in multivariate regression analysis, preoperative histological risk classification was a stronger predictor of DSS than DNA ploidy. Conclusions: Non-diploid curettage is significantly associated with aggressive clinicopathological phenotype, lymph node metastasis, and poor survival in endometrial cancer. The prognostic effect was also observed among subgroups with (presumably) less aggressive traits, such as low FIGO stage and negative lymph node status. Our results indicate curettage DNA ploidy as a possible supplement to existing parameters used to tailor surgical treatment. ELER VM, 1991, CANCER, V67, P3093

- Surgery is the cornerstone in primary endometrial cancer treatment, and with curative intent it constitutes total hysterectomy and bilateral salpingo-oopherectomy. In addition, lympha-denectomy is performed in selected patients dependent on a preoperative risk assessment. Recent reports from the surgical approach to esophageal cancer reveal worse outcome when esophagectomy is performed later in the week. On this basis, we set out to explore weekday of surgery in relation to long-term outcome in 1302 endometrial cancer patients prospectively included in the MoMaTEC multicenter study. Day of surgery was dichotomized as early-week (Monday-Tuesday) or late-week (Wednesday-Friday), and evaluated as a discrete variable. Adjusted for patient age, Body Mass Index (BMI), FIGO stage, and histology, surgery performed later in the week was associated with 50.9% increased risk of all-cause death (p = 0.029). Among high-stage patients (FIGO stage III and IV), 5-year disease-specific survival proportions were 53.0% for early-week operated vs. 40.2% for lateweek operated (p = 0.005 for difference). In multivariate survival analysis of high-stage patients, late-week surgery correlated with an increased risk of disease-specific death by 88.7% and all-cause death by 76.4% (p<0.017). Evaluating only patients who underwent lymphadenectomy, the adverse prognostic effect of being operated late-week remained for both disease-specific and all-cause death (HR 2.151 and HR 1.912, p = 0.004). Whether surgery was performed early- or late-week was not influenced by patient age, BMI, preoperative histology risk classification, FIGO stage or postoperative histology (all p>0.05). In conclusion, endometrial cancer surgery conducted late-week is associated with worse long-term outcome. Our findings are most evident among patients with higher FIGO stages, and patients who underwent more extensive surgical procedure (lymphadenectomy). With support from other studies, our results suggest that high-risk patients may benefit from surgery earlier in the week.

- Endometrial cancer is the most common gynecological cancer in developed countries and the observed rise in incidence is mainly caused by life style factors including obesity and diabetes. The management of the disease has undergone major changes in the past 5-10 years. Morphological and genetic studies constitute the basis for the new classification of the disease, and data emerging from the Cancer Genome Atlas suggest that genomic patterns differ within the two types of endometrial cancer. The prognosis seems to be related to occult lymphatic spread but the role of lymphadenectomy is heavily debated. Development of novel biomarkers, sentinel lymph node technique and refined radiological methods may reduce the need of comprehensive staging in the future. The results from the Cancer Genome Atlas suggest that women with endometrial cancer may benefit from »targeted therapies« in the evolving era of personalised medicine.

- Background: The aim of this study is to evaluate the impact of lymphovascular space invasion (LVSI) on the risk of lymph node metastases and survival in endometrioid endometrial adenocarcinoma. Material and methods: As regard the study design, this is a cohort study based on prospectively recorded data. Patients with endometrioid endometrial adenocarcinoma registered in the Swedish Quality Registry for Gynecologic Cancer 2010-2017 with FIGO stages I-III and verified nodal status were identified (n = 1587). LVSI together with established risk factors, namely DNA ploidy, FIGO grade, myometrial invasion and age, were included in multivariable regression analyses with lymph node metastases as the dependent variable. Associations between the risk factors and overall and relative survival were included in multivariable models. Estimates of risk ratios (RR), hazard ratios (HR), excess mortality rate ratios (EMR), and 95% confidence intervals (95% CI) were calculated. Results: The presence of LVSI presented the strongest association with lymph node metastases (RR = 5.46, CI 3.69-8.07, p < .001) followed by deep myometrial invasion (RR = 1.64, CI 1.13-2.37). In the multivariable survival analyses, LVSI (EMR = 7.69, CI 2.03-29.10,) and non-diploidy (EMR = 3.23, CI 1.25-8.41) were associated with decreased relative survival. In sub-analyses including only patients with complete para-aortic and pelvic lymphadenectomy and negative lymph nodes (n = 404), only LVSI (HR = 2.50, CI 1.05-5.98) was associated with a worsened overall survival. Conclusion: This large nationwide study identified LVSI as the strongest independent risk factor for lymph node metastases and decreased survival in patients with endometrioid adenocarcinomas. Moreover, decreased overall survival was also seen in patients with LVSI-positive tumors and negative lymph nodes, indicating that hematogenous dissemination might also be important.

- Objectives To assess the effects on relative survival of established and new prognostic factors in stage I-III grade 1-3 endometrioid endometrial carcinoma and in the subgroup of stage I grade 1-2. Methods This was a population-based, retrospective study including all women (n=1113) in the western Swedish healthcare region diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage I-III grade 1-3 endometrioid endometrial carcinoma in 2006-2011. Histology, grade, stage, and age were prospectively reported to the regional clinical and national cancer registers. DNA ploidy and S-phase fraction were analyzed by flow cytometer. S-phase fraction cut-off was set at >= 8%. Tumor biopsies were classified as diploid if there was one G0/G1 peak or the DNA index was 1.0 +/- 0.04. Overexpression of p53 as determined by immunohistochemistry was positive if strong nuclear staining was found in >30% of the neoplastic cells. Results Based on univariable statistical analyses we found that 5-year relative survival was significantly associated with S-phase fraction, DNA ploidy, p53, stage, grade, and age. Excess mortality for S-phase fraction >= 8%, aneuploidy, and p53 overexpression was 8, 14, and 8 and times higher, respectively. However, in a multivariable regression model, adjusted for stage, grade, and age, S-phase fraction, DNA ploidy, and p53 were not statistically independent prognostic factors (p=0.413, p=0.107, p=0.208, respectively) for 5-year relative survival in stage I-III grade 1-3 endometrioid endometrial carcinoma. In a subgroup analysis of stage I grade 1-2, aneuploidy identified a subgroup with impaired 5-year relative survival. Conclusion We can conclude that S-phase fraction, DNA ploidy, and p53 overexpression did not improve identification of high-risk patients by stage, grade, and age in stage I-III endometrioid endometrial carcinoma. In stage I, aneuploidy and grade 2 predicted lower relative survival rates than other variables.

- Objective: To evaluate if increased individualization in endometrial cancer classification/treatment affected relative survival. Methods: The present retrospective register-based population study included data from all women in the western Swedish healthcare region who were treated for endometrial cancer between January 1, 1995, and December 31, 2011. Outcomes and prognostic data were retrieved from the western Swedish healthcare region's cancer and clinical endometrial cancer registries. Patients were stratified based on two different treatment programs (cohort 1 January 1, 1995, to September 10, 2006, and cohort 2 September 11, 2006, to December 31, 2011) and relative survival was compared. Results: Data from 4338 patients were included; 2936 in cohort 1 and 1402 in cohort 2. Among endometrioid endometrial carcinomas, the 5-year relative survival rate for did not differ significantly between the groups (P=0.751); radiotherapy was used more frequently in cohort 1 (P<0.001). Among non-endometrioid endometrial carcinomas, relative survival was lower in cohort 1 (P=0.006); radiotherapy use was more frequent in cohort 1 and chemotherapy use was more frequent in cohort 2 (P<0.001). Conclusion: Increased individualization in endometrioid endometrial cancer management did not improve relative survival. Improved relative survival was observed for non-endometrioid endometrial cancer; possibly due to increased adjuvant chemotherapy use.
