- 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.

- BackgroundThe aim of this study was to analyze overall survival in endometrial cancer patients’ FIGO stages I-III in relation to surgical approach; minimally invasive (MIS) or open surgery (laparotomy).MethodsA population-based retrospective study of 7275 endometrial cancer patients included in the Swedish Quality Registry for Gynecologic Cancer diagnosed from 2010 to 2018. Cox proportional hazard models were used in univariable and multivariable survival analyses.ResultsIn univariable analysis open surgery was associated with worse overall survival compared with MIS hazard ratio, HR, 1.39 (95% CI 1.18–1.63) while in the multivariable analysis, surgical approach (MIS vs open surgery) was not associated with overall survival after adjustment for known risk factors (HR 1.12, 95% CI 0.95–1.32). Higher FIGO stage, non-endometrioid histology, non-diploid tumors, lymphovascular space invasion and increasing age were independent risk factors for overall survival.ConclusionThe minimal invasive or open surgical approach did not show any impact on survival for patients with endometrial cancer stages I-III when known prognostic risk factors were included in the multivariable analyses.

- Background: Research focusing on patients’ perceptions of the quality of gynecological cancer care is needed.Objective: To adapt the Quality from the Patient’s Perspective instrument for use in gynecological cancer care (QPP-GynCa) and describe patients’ perceptions of their quality of care in terms of the care received and the subjective importance of the aspects of care.Methods: A cross-sectional study 6–8 months after diagnosis was conducted, involving 1511 patients (response rate of 50.4%) included in the Swedish quality registry for gynecologic cancer.Results: The exploratory factor analysis (n = 1431) resulted in the QPP-GynCa with a 5-factor structure and an eigenvalue of ≥1, explaining 73.1% of the total scale variance. The final 27-item version of the QPP-GynCa consisted of 18 items with 8 additional single items and 1 global single item. The Cronbach’s alpha was acceptable for most factors (>.80). Subjective importance scores were higher than corresponding quality of care scores for care received (P ≤ .01)in all dimensions, factors, and items.Conclusions: The QPP-GynCa instrument reflects all 4 dimensions of the theoretical model of quality of care and achieved good validity as a reliable instrument in assessing the quality of gynecological cancer care.Implication for Practice: Information related to self-care, aspects of sexuality, and reducing patient waiting times need improvement.What Is Foundational: This study contributes to a better understanding of quality of gynecological cancer treatment and care. The validated QPP-GynCa instrument will be a platform for more research on how this group of patients experience their received care, as well as importance of each aspect of care.

- 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.
