- 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 interobserver reproducibility among ultrasound experts and gynecologists in the prediction by transvaginal ultrasound of deep myometrial and cervical stromal invasion in women with endometrial cancer. Methods Sonographic videoclips of the uterine corpus and cervix of 53 women with endometrial cancer, examined preoperatively by the same ultrasound expert, were integrated into a digitalized survey. Nine ultrasound experts and nine gynecologists evaluated presence or absence of deep myometrial and cervical stromal invasion. Histopathology from hysterectomy specimens was used as the gold standard. Results Compared with gynecologists, ultrasound experts showed higher sensitivity, specificity and agreement with histopathology in the assessment of cervical stromal invasion (42% (95% CI, 31-53%) vs 57% (95% CI, 45-68%), P < 0.01; 83% (95% CI, 78-86%) vs 87% (95% CI, 83-90%), P = 0.02; and kappa, 0.45 (95% CI, 0.40-0.49) vs 0.58 (95% CI, 0.53-0.62), P< 0.001, respectively) but not of deep myometrial invasion (73% (95% CI, 66-79%) vs 73% (95% CI, 66-79%), P = 1.0; 70% (95% CI, 65-75%) vs 69% (95% CI, 63-74%), P = 0.68; and kappa, 0.48 (95% CI, 0.44-0.53) vs 0.52 (95% CI, 0.48-0.57), P = 0.11, respectively). Though interobserver reproducibility (in the context of test proportions 'good' and 'very good', according to kappa) regarding deep myometrial invasion did not differ between the groups (experts, 34% vs gynecologists, 22%, P = 0.13), ultrasound experts assessed cervical stromal invasion with significantly greater interobserver reproducibility than did gynecologists (53% vs 14%, P< 0.001). Conclusion Preoperative ultrasound assessment of deep myometrial and cervical stromal invasion in endometrial cancer is best performed by ultrasound experts, as, compared with gynecologists, they showed a greater degree of agreement with histopathology and greater interobserver reproducibility in the assessment of cervical stromal invasion.

- Allogeneic hematopoietic stem cell transplantation is associated with several complications and risk factors, for example, graft versus host disease (GVHD), viral infections, relapse, and graft rejection. While high levels of CD3+ cells in grafts can contribute to GVHD, they also promote the graft versus leukemia (GVL) effect. Infusions of extra lymphocytes from the original stem cell donor can be used as a treatment after transplantation for relapse or poor immune reconstitution but also they increase the risk for GVHD. In peripheral blood, 95% of T-cells express the alpha beta T-cell receptor and the remaining T-cells express the gamma delta. T-cell receptor. As alpha beta T-cells are the primary mediators of GVHD, depleting them from the graft should reduce this risk. In this pilot study, five patients transplanted with HLA-matched related and unrelated donors were treated with alpha beta T-cell depleted stem cell boosts. The majority of gamma delta T-cells in the grafts expressed V delta 2 and/or V gamma 9. Most patients receiving alpha beta-depleted stem cell boosts increased their levels of white blood cells, platelets, and/or granulocytes 30 days after infusion. No signs of GVHD or other side effects were detected. A larger pool of patients with longer follow-up time is needed to confirm the data in this study.

- Aim. The first Swedish National Guidelines for Ovarian Cancer (NGOC) were published in 2012. We aimed to evaluate surgical outcomes and survival in patients with stage IIIC-IV disease, before and after the NGOC implementation. Method. Women with primary epithelial ovarian cancer, FIGO stage IIIC?IV, registered in the Swedish Quality Registry for Gynecologic Cancer 2008?2011 and 2013?2016 were included. Surgical outcomes were analyzed, including frequency of complete cytoreduction (R0). Relative survival (RS) and excess mortality rate ratios (EMRRs) were computed as measures of survival. Univariable and multivariable regression (Poisson) were calculated. Results. In total, 3728 women were identified, 1746 before and 1982 after NGOC. After adjusting for age and stage, survival was improved 2013?2016 vs. 2008?2011 (EMRR 0.89; 95%CI:0.82?0.96, p < 0.05). For women undergoing primary debulking surgery (PDS), R0 frequency (28.9% vs. 53.3%; p < 0.001) and 5-year RS (29.6% (95% CI:26.8?32.8) vs. 37.4% (95%CI:33.6?41.7)) were increased, but fewer patients (58% vs. 44%, p < 0.001) underwent PDS after NGOC implementation. Median survival for the PDS cohort increased from 35 months (95%CI,32.8?39.2) to 43 months (95%CI,40.9?46.4). In the neoadjuvant chemotherapy (NACT) + interval debulking surgery (IDS) cohort, R0 increased (36.8% to 50.1%, p < 0.001), but not 5-year RS (17.5% vs. 20.7%,ns). Compared to PDS, the EMRR was 1.32 (95%CI,1.19 & ndash;1.47, p < 0.001) for NACT+IDS and 3.00 (95% CI,2.66 & ndash;3.38, p < 0.001) for chemotherapy alone. In multivariable analyses, PDS, R0, age <= 70 years, and stage IIIC were found to be independent factors for improved RS. Conclusion. Implementation of the first National Guidelines for Ovarian Cancer improved relative survival in advanced ovarian cancer. (c) 2021 Published by Elsevier Inc.

- Background Poor survival rates in different cancer types are sometimes blamed on diagnostic and treatment delays, and it has been suggested that such delays might be related to sociodemographic factors such as education and ethnicity. We examined associations of the wait time from diagnosis to surgery and survival in endometrial cancer (EC) and explored patient and tumour factors influencing the wait time. Material and methods In this historical population-based cohort study, The Swedish Quality Registry for Gynaecologic Cancer (SQRGC) was used to identify EC patients who underwent primary surgery between 2010 and 2018. Factors associated with a wait time > 32 d were analysed with logistic regression. The 32-d time point was defined in accordance with the Swedish Standardisation Cancer Care programme. Adjusted Poisson regression analyses were used to analyse excess mortality rate ratio (EMRR). Results Out of 7366 women, 5535 waited > 32 d for surgery and 1098 > 70 d. The overall median wait time was 44 d. The factors most strongly associated with a wait time > 32 d were surgery at a university hospital (adjusted odds ratio [OR] 1.34, 95% confidence interval [CI] 1.08-1.66) followed by country of birth (OR 1.31, 95% CI 1.10-1.55) and year of diagnosis. There were no associations between wait time and histology or age. A wait time < 15 d was associated with higher mortality (adjusted EMRR 2.29,95% CI 1.36-3.84) whereas no negative survival impact was seen with a wait time of 70 d. Age, tumour stage, histology and risk group were highly associated with survival, whereas education, country of origin and hospital level did not have any impact on survival. Conclusions Surgery within the first two weeks after EC diagnosis was associated with worsened survival. A prolonged wait time did not seem to have any significant adverse effect on prognosis.
