    • This study aims to investigate acceptance of vaginal self-sampling for high-risk human papilloma virus (HPV) among long-term screening non-attenders at increased cervical cancer risk and to identify leverage points to promote screening adherence among these women. Forty-three long-term screening non-attenders performed home vaginal self-sampling for HPV, had positive HPV results, and subsequently attended gynecologic examination. Sixteen (37.2%) had high-grade cervical intraepithelial neoplasia (CIN2 or 3), and two had invasive cervical cancer. Forty-one of these women completed a questionnaire concerning Specific Knowledge about HPV, CIN, and cervical cancer, potential barriers to screening and views about self-sampling. Results were compared with 479 women treated for CIN2+ who attended gynecologic follow-up and also performed self-sampling. Significant multivariate predictors of long-term non-attender status compared with referents were low Specific Knowledge, high confidence in self-sampling, and potential barriers-refraining from activity to attend gynecologic examination, needing another's help to attend, and long travel time. Non-attenders citing fear/refraining from gynecologic examination as why they preferred self-sampling significantly more often had lowest Specific Knowledge compared with other non-attenders. All non-attenders could envision themselves doing self-sampling again while only 74% of referents endorsed this statement (p = 0.0003). We conclude that HPV self-sampling is an acceptable option for women at increased cervical cancer risk who have been long-term screening non-attenders. Educational outreach to enhance Specific Knowledge about HPV, CIN and cervical cancer is critical. Those non-attenders who explicitly avoid gynecologic examinations need special attention.

  • Incomplete excision of cervical intraepithelial neoplasia as a predictor of the risk of recurrent disease : a 16-year follow-up study
  • 2020
  • Ingår i: American Journal of Obstetrics and Gynecology. - : Elsevier. - 0002-9378 .- 1097-6868. ; 222:2, s. 172.e1-172.e12

    • BACKGROUND: Women treated for high-grade cervical intraepithelial neoplasia (CIN, grade 2 or 3) are at elevated risk of developing cervical cancer. Suggested factors identifying women at highest risk for recurrence post-therapeutically include incomplete lesion excision, lesion location, size and severity, older age, treatment modality and presence of high-risk human papilloma virus (hrHPV) after treatment. This question has been intensively investigated over decades, but there is still substantial debate as to which of these factors or combination of factors most accurately predict treatment failure.OBJECTIVES: In this study, we examine the long-term risk of residual/recurrent CIN2+ among women previously treated for CIN2 or 3 and how this varies according to margin status (considering also location), as well as comorbidity (conditions assumed to interact with hrHPV acquisition and/or CIN progression), post-treatment presence of hrHPV and other factors.STUDY DESIGN: This prospective study included 991 women with histopathologically-confirmed CIN2/3 who underwent conization in 2000-2007. Information on the primary histopathologic finding, treatment modality, comorbidity, age and hrHPV status during follow-up and residual/recurrent CIN2+ was obtained from the Swedish National Cervical Screening Registry and medical records. Cumulative incidence of residual/recurrent CIN2+ was plotted on Kaplan-Meier curves, with determinants assessed by Cox regression.RESULTS: During a median of 10 years and maximum of 16 years follow-up, 111 patients were diagnosed with residual/recurrent CIN2+. Women with positive/uncertain margins had a higher risk of residual/recurrent CIN2+ than women with negative margins, adjusting for potential confounders (hazard ratio (HR)=2.67; 95% confidence interval (CI): 1.81-3.93). The risk of residual/recurrent CIN2+ varied by anatomical localization of the margins (endocervical: HR=2.72; 95%CI: 1.67-4.41) and both endo- and ectocervical (HR=4.98; 95%CI: 2.85-8.71). The risk did not increase significantly when only ectocervical margins were positive/uncertain. The presence of comorbidity (autoimmune disease, human immunodeficiency viral infection, hepatitis B and/or C, malignancy, diabetes, genetic disorder and/or organ transplant) was also a significant independent predictor of residual/recurrent CIN2+. In women with positive hrHPV findings during follow-up, the HR of positive/uncertain margins for recurrent/residual CIN2+ increased significantly compared to women with hrHPV positive findings but negative margins.CONCLUSIONS: Patients with incompletely excised CIN2/3 are at increased risk of residual/recurrent CIN2+. Margin status combined with hrHPV results and consideration of comorbidity may increase the accuracy for predicting treatment failure.

  • Cadmium Intake as a Prognostic Factor in Endometrial Cancer : A Swedish Cohort-Based Study
  • 2021
  • Ingår i: Nutrition and Cancer. - : Routledge. - 0163-5581 .- 1532-7914. ; , s. 1-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Metalloendocrinology is a new interdisciplinary field, which was established due to the importance of connections between inorganic chemicals and hormonal mechanisms. The role of cadmium in hormone-related tumors is an excellent example of this connection, as cadmium mimics estrogen in the human body. Since endometrial cancer (EC) is hormone-related, it is well-suited for assessing the estrogenic effects of cadmium. Therefore, the present study aims to explore the role of dietary cadmium intake in the progression-free survival (PFS) and overall survival (OS) in women with EC. Dietary cadmium intake was estimated based on a large cohort of Swedish women (n = 416) with EC. Median dietary cadmium intake was then analyzed in relation to different tumor characteristics and clinical outcomes. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Median daily dietary cadmium intake in the cohort was 13.1 μg (interquartile range 25%-75%=6.4). High dietary cadmium intake (μg/day) was associated with significantly decreased OS in the study cohort (HR = 0.956, 95% CI = 0.914-1.001, p = 0.05). Dietary cadmium intake was not associated with PFS (HR = 0.975, 95% CI = 0.924-1.028, p = 0.348). Therefore, our results indicate that high dietary cadmium intake could be associated with poor outcome in women with EC.

  • PGC1α and VDAC1 expression in endometrial cancer
  • 2021
  • Ingår i: Molecular and clinical oncology. - : Spandidos Publications. - 2049-9450 .- 2049-9469. ; 14:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Endometrial cancer (EC) is one of the ten most common gynecological cancers. As in most cancers, EC tumour progression involves alterations in cellular metabolism and can be associated with, for instance, altered levels of glycolytic enzymes. Mitochondrial functions and proteins are known to serve key roles in tumour metabolism and progression. The transcriptional coactivator peroxisome proliferator-activated receptor gamma coactivator 1 (PGC1α) is a major regulator of mitochondrial biogenesis and function, albeit of varying prognostic value in different cancers. The voltage-dependent anion channel type 1 (VDAC1) regulates apoptosis as well as metabolite import and export over the mitochondrial outer membrane, and is often used for comparative quantification of mitochondrial content. Using immunohistochemistry, the present study examined protein expression levels of PGC1α and VDAC1 in tumour and paired benign tissue samples from 148 patients with EC, in order to examine associations with clinical data, such as stage and grade, Ki-67, p53 status, clinical resistance and overall survival. The expression levels of both PGC1α and VDAC1, as well as a PGC1α downstream effector, were significantly lower in tumor tissues than in benign tissues, suggesting altered mitochondrial function in EC. However, Kaplan-Meier, log rank and Spearman's rank correlation tests revealed that their expression was not correlated with survival and clinical data. Therefore, PGC1α and VDAC1 are not of major prognostic value in EC.

  • Which dietary and everyday life habits affect endometrial cancer recurrence? The machine gives the answer
  • 2020
  • Ingår i: International Journal of Gynecological Cancer. - : Lippincott Williams & Wilkins. - 1048-891X .- 1525-1438. ; 30:Suppl. 4, s. A32-A33
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Introduction/Background: The increased life expectancy and westernization of the lifestyle are considered the major contributors to a sustainable rise in endometrial cancer (EC) rates. The factors predicting EC recurrence include patient age and tumour characteristics, such as type, differentiation, and depth of invasion. At the same time, recent studies testify the impact of meal and exercises on the course of various diseases. What are the food preferences and activities that could influence the ultimate risk of EC relapse and death?Methodology: The study included 481 women who previously underwent a hysterectomy due to EC at Karolinska University Hospital. The participants filled an extensive questionnaire on their dietary habits and everyday routines. Related clinical data was obtained through the National e-health system. It resulted in a large dataset with more than 180 variables, which was processed using the Random Survival Forest (RSF) approach. The latter is applied to a right-censored data and uses a collection of decision trees to rank the variables by their importance for the occurrence of an event. The top-ranked variables were further investigated with the Cox proportional hazards model. Analyzes were performed using the RandomForestSRC package for Python.Results: The consumption of the fried potatoes significantly increased the risk of EC relapse and death [HR=8.62 (2.22–33.56), p=0.002; HR=6.00 (1.06–34.01), p=0.043, respectively), the latter persisted after adjustment for body mass index, age and smoking status. Besides, each additional serving of sweetened soda drinks increased the risk of death [3.262 (1.834–5.800), p=0.0001]. In contrast, physical activity was beneficial with each additional Metabolic Equivalent per day decreasing the risk of death by 7.3% [HR=0.927 (0.892–0.964), p< 0.0001).Conclusion: We hypothesise that the fried potatoes’ detrimental effect may be related to the acrylamide, which is formed in starch-rich foods under high-temperature conditions. It acts as a carcinogen and endocrine disruptor, causing the endometrial hyperplasia and EC in animal studies. Sweetened beverages cause a rise in insulin, which in turn inhibits sex-hormone binding protein. This results in higher levels of circulating free oestrogens. Also, insulin has mitogenic and anti-apoptotic properties, further inducing the endometrium proliferation. The favorable influence of regular physical activity on EC relapse and death is in accordance with previous studies, including recent meta-analysis.Therefore, we encourage women treated for EC to consider reducing sweetened beverages and fried potatoes consumption and increasing physical activity.
