- Objective. The aim of the study was to determine survival outcome in patients with serous cancer in the ovary, fallopian tube, peritoneum and of undesignated origin. Methods. Nation-wide population-based study of women 18 years with histologically verified non-uterine serous cancer, included in the Swedish Quality Registry for primary cancer of the ovary, fallopian tube and peritoneum diagnosed 2009-2013. Relative survival (RS) was estimated using the Ederer II method. Simple and multivariable analyses were estimated by Poisson regression models. Results. Of 5627 women identified, 1246 (22%) had borderline tumors and 4381 had malignant tumors. In total, 2359 women had serous cancer; 71% originated in the ovary (OC), 9% in the fallopian tube (FTC), 9% in the peritoneum (PPC) and 11% at an undesignated primary site (UPS). Estimated RS at 5-years was 37%; for FTC 54%, 40% for OC, 34% for PPC and 13% for UPS. In multivariable regression analyses restricted to women who had undergone primary or interval debulldng surgery for OC, FTC and PPC, site of origin was not independently associated with survival. Significant associations with worse survival were found for advanced stages (RR 2.63, P<0.001), moderate (RR 1.90, P<0.047) and poor differentiation (RR 2.20, P<0.009), neoadjuvant chemotherapy (RR1.33, P<0.022), residual tumor (RR 2.65, P<0.001) and platinum single (2.34, P<0.001) compared to platinum combination chemotherapy. Conclusion. Survival was poorer for serous cancer at UPS than for ovarian, fallopian tube and peritoneal cancer. Serous cancer at UPS needs to be addressed when reporting and comparing survival rates of ovarian cancer. (C) 2016 Elsevier Inc. All rights reserved.

Disclosing the invisible : experiences, outcomes and quality of endometriosis healthcare
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Many women with endometriosis report that their symptoms are normalized and trivialized when they seek medical care and they often experience diagnostic delays, ineffective treatments and physiological, psychological and social consequences. However, there is a knowledge gap when it comes to women’s experiences of different aspects of endometriosis healthcare, and the quality of that care. Aim: The aim of this thesis was to identify, describe and analyse the experiences, encounters and outcomes of endometriosis healthcare from different perspectives. Design and Method: This thesis is a summary of four studies with different methods and designs. Study I and II were qualitative interview studies in which nine women with a laparoscopy-verified endometriosis diagnosis (study I) and 25 healthcare professionals (HCPs) (study II) described their experiences of healthcare encounters related to endometriosis symptoms. The interviews were analysed using interpretive phenomenology (study I) and conventional content analysis (study II). Study III was a cross-sectional observational comparative study measuring pain thresholds, health-related quality of life (HRQoL) and symptoms of anxiety and depression using quantitative sensory testing (QST) and questionnaires in order to determine pain thresholds in healthy women (n=55) and women with persistent pelvic pain (PPP), with (n=14) and without (n=23) a confirmed diagnosis of endometriosis. The correlations between pain thresholds and duration of PPP, HRQoL and symptoms of anxiety and depression were also analysed. Study IV was a quantitative observational study using register data from the National Quality Register for Gynaecological Surgery. Patient-reported experience measures (PREM) and patient-reported outcome measures (PROM) after benign hysterectomy were analysed and compared in women with and without PPP and endometriosis (study IV). Results: The results of the thesis are summarized in three themes: The struggle to visualize the pain, The endometriosis diagnosis as a key to understanding and enduring persistent pelvic pain and Healthcare encounters as potentially life changing. In the first theme, women and HCPs described the healthcare encounters concerning endometriosis symptoms as troublesome (study I, II). The women struggled with disclosing, visualizing and communicating their hidden pain to the HCPs (study I), and HCPs expressed insecurity and limited knowledge when caring for these women (study II). Study III showed widespread reduced pain thresholds among women with PPP compared with healthy controls, and a significant positive correlation between duration of PPP and reduced pain thresholds . Study III also showed a reduced HRQoL and higher prevalence of anxiety and depressive symptoms among women with PPP, which were also described by the women (study I).The importance of getting a diagnosis was described in the second theme by both women and HCPs (study I, II), but women with PPP with and without endometriosis diagnosis did not differ significantly in their pain thresholds or psychosocial outcomes in study III. Likewise, women with PPP with and without endometriosis gave more equal PREM and PROM answers than women in the pain-free comparison group. Overall, women undergoing hysterectomy on benign indications were satisfied with the experience and outcomes of the surgery (study IV).As described in the last theme, healthcare encounters could be constructive or destructive. Positive experiences could make the symptoms easier to endure. The constructive encounters were often characterized by a holistic approach and a care structured in multidisciplinary teams. Conclusion and clinical implications: The results suggest that PPP should be taken seriously and treated actively in order to minimize the risk of physiological and psychological consequences, such as reduced pain thresholds, lower HRQoL and symptoms of anxiety and depression. Unrelieved PPP could also be an explanatory factor for long-term physiological consequences, such as lower PREM and PROM after hysterectomy.High-quality endometriosis healthcare should provide an interaction of physical, psychological and social factors. If women experience that HCPs acknowledge their pain and the effect of pain on HRQoL and mental health, and are offered proper pain-relieving treatment, healthcare encounters could change their lives.

- INTRODUCTION: Endometriosis is a gynecological disorder that may cause considerable pelvic pain in women of fertile age. Determining pain mechanisms is necessary in order to optimize the treatment of the disease. The objective of the study was to evaluate pain thresholds in women with persistent pelvic pain with and without confirmed endometriosis, and healthy, unaffected controls, and analyze how pain thresholds in these cohorts related to duration of pelvic pain, quality of life, and symptoms of anxiety and depression.MATERIAL AND METHODS: Pain thresholds for heat, cold and pressure were assessed with quantitative sensory testing on six locations on a reference group of 55 healthy women and on 37 women with persistent pelvic pain who had been admitted for diagnostic laparoscopy on the suspicion of endometriosis. Validated instruments were applied to assess quality of life and symptoms of anxiety and depression. Data were analyzed by means of uni- and multivariate analysis of variance and Spearman's rank-order correlation.RESULTS: The women with persistent pelvic pain had significantly lower pain thresholds compared with the reference women. In the women with pain, no differences were observed in pain thresholds between women with (n = 13) and women without (n = 24) biopsy-proven endometriosis. The duration of pelvic pain correlated significantly positively with reduced pain thresholds, ie, the longer the duration, the more sensitization. In the persistent pelvic pain group, pain thresholds for heat correlated significantly with the Short Form Health Survey 36 dimension of bodily pain, and thresholds for cold correlated with Short Form Health Survey 36 bodily pain and with symptoms of depression.CONCLUSIONS: Our results showed widespread alterations in pain thresholds in women with persistent pelvic pain that are indicative of central sensitization and a time-dependent correlation. Women with pelvic pain and suspicion of endometriosis should probably be treated more thoroughly to prevent or at least minimize the concomitant development of central sensitization.

- The International Federation of Gynecology and Obstetrics (FIGO) ovarian cancer staging system includes no sub-stage for lymph nodes (LN) as only distant disease manifestation. We explore the prognostic implication of LN as only stage IV classifier in serous ovarian cancer.This is a nation-wide, population-based study on 551 women with serous stage IV cancers diagnosed between 2009-2014. We compare overall survival (OS) in women with LN as only distant metastatic site to those with pleural metastases only and to patients with other/multiple stage IV manifestations. Cox regression models were used for uni- and multivariable estimations.Of 551stage IV cases, distant metastatic site was registered in 433. Median OS for women with LN (n=51) was 41.4 months, compared to 25.2 and 26.8 months for patients with pleural (n=195) or other/multiple (n=187) distant metastases (p=.0007). The corresponding five-year survival rates were 32, 11 and 22%, respectively. Multivariable analyzes confirmed shorter survival for women with pleural (HR 2.99, p=.001) or other/multiple distant sites (HR 2.67, p=.007), as compared to LN cases. LN only patients lived 9.1 months longer after primary than after interval surgery, but this difference was not significant (p=.245).Women with stage IV serous ovarian cancer having lymph nodes as only distant metastatic site live longer than other stage IV patients.

- Objective There are limited prospective data on the evaluation of quality of life in patients undergoing robotic hysterectomy for endometrial cancer. Our objective was to determine whether post-operative recovery differs between robotic and abdominal hysterectomy.Methods At a Swedish tertiary referral university hospital, 50 women with low-risk endometrial cancer scheduled for surgery between February 2012 and May 2016 were included in a randomized trial. Surgery was performed according to principles for minimal invasive surgery. Anesthesia and peri-operative care followed a standardized enhanced recovery after surgery program in both groups. The EuroQol Group form EQ-5D and the Short Form-36 were used to evaluate patients' health-related quality of life. The Swedish Postoperative Symptoms Questionnaire assessed symptoms pre-operatively, daily for 7 days from the day of surgery, and then weekly until 6 weeks post-operatively. Data were analyzed by means of non-parametric tests and repeated measures ANOVA. To evaluate the time-dependent occurrence of complications, Kaplan-Meier survival and Cox proportional-hazard models were used.Results A total of 50 women were enrolled in the study (25 robotic and 25 abdominal hysterectomy). Median age (68 years vs 67 years), estimated blood loss (50 mL vs 50 mL), length of hospital stay de facto (53 hours vs 51 hours), and time to meet discharge criteria (36 hours vs 36 hours) in the robotic and abdominal groups, respectively, did not differ significantly (p>0.05) Women in the robotic hysterectomy group recovered significantly faster (p=0.01) in the EQ-5D health index, and reached their pre-operative level after approximately 3 weeks, nearly 2 weeks earlier than the abdominal group. Differences regarding improvement in health-related quality of life (Short Form-36) were statistically significant in general health and social functioning only, and were in favor of robotic hysterectomy. Consumption of analgesics, pain intensity, and symptom sum score post-operatively were equal. Occurrence of complications was an independent risk factor and influenced significantly the EQ-5D health index, length of hospital stay, pain intensity, opioid consumption, and symptom sum score adversely.Conclusion Robotic hysterectomy in the setting of an enhanced recovery after surgery program led to faster recovery in health-related quality of life compared with abdominal hysterectomy.

- Aim: The aim of this study is to evaluate the quality of data on endometrial (EC) and ovarian, fallopian tube, peritoneal, abdominal or pelvic cancers (OC) registered in the Swedish Quality Register of Gynecologic Cancer (SQRGC).Method: A random sample of 500 patients was identified in the SQRGC and their medical charts were reviewed for re-abstraction of 31 selected core variables by an independent validator. The data in the SQRGC and the re-abstracted data were compared. The data were collected from 25 hospitals evenly distributed throughout Sweden. The main outcomes were comparability, timeliness, completeness and validity. Coverage was compared with the National Cancer Register (NCR). Timeliness was defined as the speed of registration i.e. when patients were registered in the SQRGC relative to date of diagnosis. Internationally accepted coding systems for stage, grading and histologic type were used ensuring a high degree of comparability. Correlations were estimated using Pearson’s correlation coefficient and Cohen´s kappa coefficient.Results: The completeness was 95%. The timeliness was 88–91% within 12 months of diagnosis. The median degree of agreement between re-abstracted data and data in the SQRGC was 82.1%, with a median kappa value of 0.73 for ordinate variables and a median Pearson’s correlation coefficient of 0.96. The agreements for the type of surgery were 76% (95% CI 70–81%; kappa 0.49) and type of primary treatment 90% (95% CI 87–94%; kappa 0.85) in OC and in EC 88% (95% CI 84–93%; kappa 0.84). The agreements for the FIGO stage were in OC and EC 74% (95% CI 68–80%; kappa 0.69) and 87% (95% CI 82–91%; kappa 0.79), respectively.Conclusions: The data in the Swedish Quality Register for Gynecologic Cancer are of adequate quality in order to be used as a basis for research and to evaluate possible differences in treatment, lead times and treatment results.

- The role of lymphadenectomy in the management of early endometrial cancer remains controversial. In the recent ESMO-ESGO-ESTRO guidelines, lymphadenectomy is recommended for patients with endometrioid adenocarcinoma Grade 3 with deep myometrial invasion, but complete agreement was not achieved. In Sweden, DNA aneuploidy has been included as a high-risk factor. The aim of our study was to evaluate the impact of tumor histology, FIGO grade, DNA ploidy and myometrial invasion (MI) on occurrence of lymph node metastasis (LNM) in patients with endometrial cancer. The study design is a retrospective cohort study based on prospectively recorded register data. Endometrial cancer patients registered in the Swedish Quality Registry for Gynecologic Cancer 2010-2015 with FIGO Stages I-III and verified nodal status were included. Data on DNA ploidy, histology, FIGO grade and MI were included in multivariable log-binomial regression analyses with LNM as dependent variable. 1,165 cases fulfilled the inclusion criteria. The multivariable analyses revealed increased risk of LNM in patients with tumors with MI50% (risk ratio [RR]=4.1; 95% confidence interval [CI] 3.0-5.6), nonendometrioid compared to endometrioid histology (RR 1.8; CI 1.4-2.4) and FIGO Grade 3 compared to Grade 1-2 tumors (RR 1.5; CI 1.1-2.0). No statistically significant association between DNA ploidy status and LNM was detected. This population-based, nation-wide study in women with endometrial cancer confirms a strong association between MI50%, nonendometrioid histology and FIGO Grade 3, respectively, and LNM. DNA ploidy should not be included in the preoperative decision making of removing nodes or not. What's new? Whether lymphadenectomy is beneficial for women with endometrial cancer remains uncertain. Moreover, additional studies are needed to explore factors that reliably predict lymph node metastasis (LNM). Here, multiple factors, including tumor histology, grade of differentiation and DNA aneuploidy, were evaluated for associations with LNM risk in women with endometrial cancer and verified lymph node status. Most significantly, deep myometrial invasion in tumors increased LNM risk fourfold, whereas DNA ploidy had essentially no impact on LNM risk. The findings confirm the predictive relevance of myometrial invasion, histology and grade reported in previous single-center and multicenter studies.

Tidskriftsartikel (refereegranskat)abstract
- Background: In squamous cell vulvar cancer, sentinel node biopsy is accepted as standard treatment in well-defined patient groups and has reduced surgical morbidity considerably. Currently, due to the lack of evidence, it cannot be offered to patients with tumors of 4 cm diameter or greater or with multifocal tumors, or in local recurrences. Primary objective: This study is primarily a pilot and feasibility trial, aiming to evaluate if the prerequisites concerning detection rate and negative predictive value are satisfactory before the implementation of a multinational trial. Study hypothesis: Sentinel node biopsy has an acceptable negative predictive value and detection rate in the study cohort. Trial design: This study is planned as a prospective, national, multicenter interventional trial. Participating patients will undergo a sentinel node biopsy in addition to an inguinofemoral lymphadenectomy. Inclusion and exclusion criteria: Inclusion criteria: for women in group 1, a primary tumor ≥4 cm in diameter; in group 2, a multifocal primary tumor; in group 3, a local recurrence without previous inguinofemoral lymphadenectomy or radiation to the groins; in group 4, a local recurrence, with previous inguinofemoral lymphadenectomy and/or radiation to the groins. Primary endpoint: The primary endpoints are the detection rate and the negative predictive value of the sentinel node procedure. Sample size: In each of the four study arms, recruitment of 20-30 patients is planned. Estimated dates for completing recruitment and presenting results: Recruitment will take place between November 2019 and October 2021. Results will be available in December 2021.
