- BackgroundIn low-income countries breast cancer awareness (BCA) is essential to reduce the proportion of advanced stage presentations of breast cancer. There is a lack of studies using multivariable techniques to explore factors related to BCA in low-income countries. The objective of this study was to identify to what extent women in Fiji and Kashmir, India have BCA and practice breast self-examination (BSE) as well as factors associated with BCA and BSE.MethodsA survey of women aged >= 18years was conducted in Fiji and Kashmir, India to assess BCA and rates of BSE. Comparison between Fiji and Kashmir was done using student's t-test for continuous data and chi-square for binary data. Factors associated with BCA and BSE were analysed using a multivariable logistic regression for Fiji and Kashmir separately.ResultsData were collected from 399 and 1982 women in Kashmir and Fiji, respectively. Of 1968 women in Fiji 57% were deemed to have an acceptable BCA compared to only 7.3% of 395 women in Kashmir. Having some education was associated with having BCA with an odds ratio of 4.7 (1.7-13) in Fiji and 10 (1.7-59) in Kashmir. Of 1976 women in Fiji 40% had tertiary education while 40% of 392 women in Kashmir had no education at all. The marital status was similar in both samples (n=1973 and 395) with 68-69% being married and 21-26% being single. The lack of female doctors or nurses with whom to discuss issues, was perceived as a problem in both countries.ConclusionsThe key finding is an association between having any level of education and BCA. This correlation was much stronger than for a family history of breast cancer and BCA. Hence, general education to illiterate women may reduce the proportion of women in low-income countries presenting with advanced-stage breast cancer.

- Background: Rural-dwellers have poorer cancer outcomes than urban counterparts, for reasons which are unclear. At healthcare institution level, poorer access to investigations and different clinical decision-making by rural primary healthcare practitioners (PCPs) could be important. Aim: To compare access to investigations, attitudes to cancer diagnosis and clinical decision-making between rural and urban PCPs. Setting: A vignette-based cross-sectional survey of rural and urban PCPs in 20 European countries. Methods: Data on PCPs' decision-making and attitudes to cancer diagnosis were based on clinical scenarios. Comparisons were made using tests of proportion, univariable and multivariable binary logistic regression. Results: Of the 1779 PCPs completing the survey 541 30.4 %) practiced rurally. Rural PCPs had significantly less direct access to all investigative modalities: ultrasound; endoscopy; x-ray and advanced screening (all p<0.001). Rural PCPs were as likely as urban PCPs to take diagnostic action (investigation and/or referral) at the index consultation in all four clinical vignettes ((OR, 95 % CI) for lung: 0.90, 0.72-1.12; ovarian: 0.95, 0.75-1.19; breast: 0.87, 0.69-1.09; colorectal: 0.98, 0.75-1.30). Rural PCPs were less likely to refer to a specialist at the index consultation for ovarian cancer (OR 0.71 95 % CI 0.51-0.99). Rural PCPs were significantly more likely to report that their patients faced barriers to accessing specialist care, but practitioners did not report greater difficulties making specialist referral than their urban counterparts Conclusions: European rural PCPs report poorer access to investigations but are at least as likely as urban PCPs to investigate or refer patients that might have cancer at the index consultation.

- ObjectiveTo investigate the frequency of physical activity among female pelvic cancer survivors (i.e., gynecological, rectal, and anal cancer survivors) and to investigate if survivors who practiced physical activity less than once a week differed from survivors practicing physical activity at least once a week with respect to urinary and fecal leakage, clinical and sociodemographic characteristics, quality of life (QoL), and depressed and anxious mood.MethodsFemale pelvic cancer survivors (n=578, mean age 64 years) answered a questionnaire 6-48 months after radiotherapy. A multivariable regression model analyzed factors covarying with frequency of physical activity. We compared QoL and depressed and anxious mood between women practicing physical activity at least or less than once a week.ResultsOf 568 women delivering data, 186 (33%) practiced physical activity less than once a week while 382 (67%) practiced physical activity at least weekly. Women who leaked a large or all volume of stools (p=0.01), had just elementary school level of education (p<0.001), smokers (p=0.049), or had lymphedema without receiving lymphedema treatment (p=0.030) were more likely to practice physical activity less than weekly (50%, 45%, 45%, and 37%, respectively) compared with other women. Women practicing physical activity at least weekly reported better QoL (p<0.001) and lower frequency of depressed mood (p=0.044) compared with the others.ConclusionsFemale cancer survivors experiencing fecal leakage were less likely to practice weekly physical activity than survivors without leakage. The survivors practicing weekly physical activity experienced better QoL and experienced depressed mood less frequently than the others.

- Background: The significance of metaphors for the experience of cancer has been the topic of extensive previous research, with “Battle” and “Journey” metaphors standing out as key. Adaptation to the patient’s use of metaphor is generally believed to be an important aspect of person-centered care, especially in palliative care. The aim of this study was to investigate the use of metaphors in blogs written in Swedish by people living with advanced cancer and explore possible patterns associated with individuals, age and gender.Methods: The study is based on a dataset totaling 2 602 479 words produced some time during the period 2007–2016 by 27 individuals diagnosed with advanced cancer. Both qualitative and quantitative procedures were used, and the findings are represented as raw frequencies as well as normalized frequencies per 10 000 words. Our general approach was exploratory and descriptive. The Mann-Whitney U test was used to analyze statistical significance.Results: Our results confirm the strong foothold of “Journey” and “Battle” metaphors. “Imprisonment” and “Burden” metaphors were also used by the majority of the individuals. The propensity to use metaphors when describing the cancer experience was found to differ extensively across the individuals. However, individuals were not found to opt for one conceptualization over the other but tended to draw on several different metaphor domains when conceptualizing their experience. Socio-demographic factors such as age or gender were not found to be strong predictors of metaphor choice in this limited study.Conclusions: Using a range of different metaphors allows individuals with advanced cancer to highlight different aspects of their experience. The presence of metaphors associated with “Journey”, “Battle”, “Imprisonment” and “Burden” across individuals could be explained by the fact that the bloggers are part of a culturally consistent cohort, despite variations in age, sex and cancer form. Awareness of metaphors commonly used by patients can enhance health professionals’ capacity to identify metaphorical patterns and develop a common language grounded in the patients’ own metaphor use, which is an important requisite for person-centered palliative care.

Tidskriftsartikel (refereegranskat)abstract
- Background: Data are lacking regarding which human papillomavirus (HPV) types cause high-grade cervical neoplasia (CIN2+) in people with HIV in Europe. We assessed which HPV types are associated with CIN2+ in women living in Sweden by HIV status. Methods: The Swedish National HIV Registry, the Swedish Population Registry, and the Swedish National Cervical Screening Registry were linked. CIN2+ tissue blocks of 130 women living with HIV (WLWH) and 234 HIV-negative women, matched for country of birth (1:2), were retrieved from bio-banks and HPV genotyped. Adjusted ORs (adjOR), stratified by country of birth, were calculated using conditional logistic regression. Matching was broken for cross-group comparisons. Results: WLWH with CIN2 were less likely to have HPV16 [14% vs. 40%; adjOR 0.1; 95% confidence interval (CI), 0.04-0.56] than HIV-negative women, but among women with CIN3, there was no difference in HPV16 prevalence by HIV status (adjOR 0.9; 95% CI, 0.51-1.70). WLWH were six times more likely to have HPV35 in CIN3 than HIV-negative women (adjOR 6.2; 95% CI, 1.3-30.4). WLWH from sub-Saharan Africa (SSA) had less 9-valent vaccine types, compared with both HIV-negative women born in Sweden (adjOR 0.1; 95% CI, 0.02-0.44) and WLWH born in Sweden (adjOR 0.1; 95% CI, 0.01-0.73), mostly because of decreased HPV16 and increased HPV35. Conclusions: WLWH from SSA were less likely to be covered by the 9-valent vaccine, mostly due to less HPV16 and more HPV35. Impact: This could have implications for HPV vaccines, currently not including HPV35, and for HPV-screening algorithms in women with origin from SSA.

Tidskriftsartikel (refereegranskat)abstract
- Background Rectal bleeding is considered an alarm symptom for colorectal cancer (CRC) but it is common and mostly caused by benign conditions. Qualitative faecal immunochemical tests (FITs) for occult blood have been used as diagnostic aids for many years in Sweden when CRC is suspected. The study aimed to evaluate the usefulness of FITs requested by primary care physicians for patients with and without histories of rectal bleeding, in the diagnosis of CRC. Methods Results of all FITs requested in primary care for symptomatic patients in the orebro region during 2015 were retrieved. Data on each patient's history of rectal bleeding was gathered from electronic health records. Patients diagnosed with CRC within 2 years were identified from the Swedish Cancer Register. The analysis focused on three-sample FITs, the customary FIT in Sweden. Results A total of 4232 patients provided three-sample FITs. Information about the presence/absence of rectal bleeding was available for 2027 patients, of which 59 were diagnosed with CRC. For 606 patients with the presence of rectal bleeding, the FIT showed sensitivity 96.2%, specificity 60.2%, positive predictive value 9.8% (95% CI 6.1-13.4) and negative predictive value 99.7% (95% CI 99.2-100) for CRC. For 1421 patients without rectal bleeding, the corresponding figures were 100%, 73.6%, 8.3% (95% CI 5.6-10.9) and 100% (95% CI 99.6-100). Conclusion The diagnostic performance of a qualitative three-sample FIT provided by symptomatic patients in primary care was similar for those with and without a history of rectal bleeding. FITs seem useful for prioritising patients also with rectal bleeding for further investigation.

Epidermal Keratinocyte Depletion during Five Weeks of Radiotherapy is Associated with DNA Double-Strand Break Foci, Cell Growth Arrest and Apoptosis: Evidence of Increasing Radioresponsiveness and Lack of Repopulation; The Number of Melanocytes Remains Unchanged

- During fractionated radiotherapy, epithelial cell populations are thought to decrease initially, followed by accelerated repopulation to compensate cell loss. However, previous findings in skin with daily 1.1 Gy dose fractions indicate continued and increasing cell depletion. Here we investigated epidermal keratinocyte response with daily 2 Gy fractions as well as accelerated and hypofractionation. Epidermal interfollicular melanocytes were also assessed. Skin-punch biopsies were collected from breast cancer patients before, during and after mastectomy radiotherapy to the thoracic wall with daily 2 Gy fractions for 5 weeks. In addition, 2.4 Gy radiotherapy four times per week and 4 Gy fractions twice per week for 5 weeks, and two times 2 Gy daily for 2.5 weeks, were used. Basal keratinocyte density of the interfollicular epidermis was determined and immunostainings of keratinocytes for DNA double-strand break (DSB) foci, growth arrest, apoptosis and mitosis were quantified. In addition, interfollicular melanocytes were counted. Initially minimal keratinocyte loss was observed followed by pronounced depletion during the second half of treatment and full recovery at 2 weeks post treatment. DSB foci per cell peaked towards the end of treatment. p21-stained cell counts increased during radiotherapy, especially the second half. Apoptotic frequency was low throughout radiotherapy but increased at treatment end. Mitotic cell count was significantly suppressed throughout radiotherapy and did not recover during weekend treatment gaps, but increased more than threefold compared to unexposed skin 2 weeks post-radiotherapy. The number of melanocytes remained constant over the study period. Germinal keratinocyte loss rate increased gradually during daily 2 Gy fractions for 5 weeks, and similarly for hypofractionation. DSB foci number after 2 Gy irradiation revealed an initial radioresistance followed by increasing radiosensitivity. Growth arrest mediated by p21 strongly suggests that cells within or recruited into the cell cycle during treatment are at high risk of loss and do not contribute significantly to repopulation. It is possible that quiescent (G0) cells at treatment completion accounted for the accelerated post-treatment repopulation. Recent knowledge of epidermal tissue regeneration and cell cycle progression during genotoxic and mitogen stress allows for a credible explanation of the current finding. Melanocytes were radioresistant regarding cell depletion. © 2020 by Radiation Research Society. All rights of reproduction in any form reserved.

Forskningsöversikt (refereegranskat)abstract
- Radiotherapy and radiation oncology play a key role in the clinical management of patients suffering from oncological diseases. In clinical routine, anatomic imaging such as contrast-enhanced CT and MRI are widely available and are usually used to improve the target volume delineation for subsequent radiotherapy. Moreover, these modalities are also used for treatment monitoring after radiotherapy. However, some diagnostic questions cannot be sufficiently addressed by the mere use standard morphological imaging. Therefore, positron emission tomography (PET) imaging gains increasing clinical significance in the management of oncological patients undergoing radiotherapy, as PET allows the visualization and quantification of tumoral features on a molecular level beyond the mere morphological extent shown by conventional imaging, such as tumor metabolism or receptor expression. The tumor metabolism or receptor expression information derived from PET can be used as tool for visualization of tumor extent, for assessing response during and after therapy, for prediction of patterns of failure and for definition of the volume in need of dose-escalation. This review focuses on recent and current advances of PET imaging within the field of clinical radiotherapy / radiation oncology in several oncological entities (neuro-oncology, head & neck cancer, lung cancer, gastrointestinal tumors and prostate cancer) with particular emphasis on radiotherapy planning, response assessment after radiotherapy and prognostication.

Tidskriftsartikel (refereegranskat)abstract
- Objective The aim was to evaluate the effects of cocreated internet-based stepped care (iCAN-DO) on anxiety, depression, posttraumatic stress, and health-related quality of life (HRQoL) in individuals with cancer and self-reported anxiety and/or depression symptoms, compared with standard care.Methods Clinically recruited individuals with breast, colorectal, or prostate cancer underwent online screening with the Hospital Anxiety and Depression Scale (HADS). Those with anxiety and/or depression symptoms (>7 on any of the HADS subscales) were randomized to iCAN-DO or standard care. iCAN-DO comprised psychoeducation and self-care strategies (step 1) and internet-based cognitive behavioral therapy (iCBT, step 2). Data were collected before randomization and at 1, 4, 7, and 10 months and analyzed with intention-to-treat regression analysis and randomization tests.Results Online screening identified 245 (27%) of 909 individuals who reported anxiety and/or depression symptoms. They were randomized to iCAN-DO (n = 124) or standard care (n = 121). Of them 49% completed the 10-month assessment, and in the iCAN-DO group 85% accessed step 1 and 13% underwent iCBT. iCAN-DO decreased the levels of symptoms of depression (−0.54, 95% confidence interval: −1.08 to −0.01, P < .05) and the proportion of individuals with symptoms of depression (P < .01) at 10 months, compared with standard care, according to HADS. There were no significant effects on anxiety, posttraumatic stress, or HRQoL.Conclusion Internet-based stepped care improves symptoms of depression in individuals with cancer. Further studies are needed to gain knowledge on how to optimize and implement internet-based support in oncology care.
