Baseline breast tissue characteristics determine the effect of tamoxifen on mammographic density change.

Tamoxifen prevents recurrence of breast cancer and is also approved for preventive, risk-reducing, therapy. Tamoxifen alters the breast tissue composition and decreases the mammographic density. We aimed to test if baseline breast tissue composition influences tamoxifen-associated density change. This biopsy-based study included 83 participants randomised to 6 months daily intake of placebo, 20, 10, 5, 2.5, or 1 mg tamoxifen. The study is nested within the double-blinded tamoxifen dose-determination trial Karolinska Mammography Project for Risk Prediction of Breast Cancer Intervention (KARISMA) Study. Ultrasound-guided core-needle breast biopsies were collected at baseline before starting treatment. Biopsies were quantified for epithelial, stromal, and adipose distributions, and epithelial and stromal expression of proliferation marker Ki67, oestrogen receptor (ER) and progesterone receptor (PR). Mammographic density was measured using STRATUS. We found that greater mammographic density at baseline was positively associated with stromal area and inversely associated with adipose area and stromal expression of ER. Premenopausal women had greater mammographic density and epithelial tissue, and expressed more epithelial Ki67, PR, and stromal PR, compared to postmenopausal women. In women treated with tamoxifen (1-20 mg), greater density decrease was associated with higher baseline density, epithelial Ki67, and stromal PR. Women who responded to tamoxifen with a density decrease had on average 17% higher baseline density and a 2.2-fold higher PR expression compared to non-responders. Our results indicate that features in the normal breast tissue before tamoxifen exposure influences the tamoxifen-associated density decrease, and that the age-associated difference in density change may be related to age-dependant differences in expression of Ki67 and PR.

Patients with both cancer and psychosis-to what extent do they receive specialized palliative care.

BACKGROUND: Schizophrenia and advanced cancer are complex conditions that impact life expectancy. This study aimed to examine the receipt of specialized palliative care (SPC) in patients with metastatic cancer and a coexisting diagnosis of psychosis compared to patients with cancer only. Secondary objectives included analyzing differences in emergency visits and place of death in relation to receipt of SPC. PATIENTS AND METHODS: This retrospective, observational registry study utilized health care consumption data from the Stockholm Regional Council. We included 23,056 patients aged >18 years who died between 2015 and 2021 with a diagnosis of metastatic cancer, hematologic malignancy, or malignant brain tumor in the Stockholm Gotland region. Among them, 320 patients had a concomitant diagnosis of psychosis. RESULTS: Patients with cancer and psychosis were less likely to receive SPC compared to patients with cancer only (61% vs. 74%, p < 0.001). Additionally, they were, on average, four and a half years younger at the time of death (68.5 years vs. 73.1 years, p < 0.0001), more likely to reside in nursing homes (25% vs. 11%, p < 0.0001), and had a higher prevalence of low area-based socioeconomic status (46% vs. 32%, p < 0.0001). Receipt of SPC was associated with reduced frequency of emergency visits and a higher probability of place of death to be at home or in a care facility outside the acute hospital. CONCLUSIONS: Patients with a coexisting diagnosis of psychosis and metastatic cancer have a lower probability of receiving SPC. Receipt of specialized palliative care was associated with reduced number of unplanned emergency visits and a lower risk for death at an acute hospital. Efforts are needed to ensure equitable provision of SPC for patients with cancer and psychosis.

Effects of tamoxifen on normal breast tissue histological composition: Results from a randomised six-arm placebo-controlled trial in healthy women.

Tamoxifen prevents recurrence of breast cancer and is suggested for preventive risk-reducing therapy. Tamoxifen reduces mammographic density, a proxy for therapy response, but little is known about its effects in remodelling normal breast tissue. Our study, a substudy within the double-blinded dose-determination trial KARISMA, investigated tamoxifen-specific changes in breast tissue composition and histological markers in healthy women. We included 83 healthy women randomised to 6 months daily intake of 20, 10, 5, 2.5, 1 mg of tamoxifen or placebo. The groups were combined to "no dose" (0-1 mg), "low-dose" (2.5-5 mg) or "high-dose" (10-20 mg) of tamoxifen. Ultrasound-guided biopsies were collected before and after tamoxifen exposure. In each biopsy, epithelial, stromal and adipose tissues was quantified, and expression of epithelial and stromal Ki67, oestrogen receptor (ER) and progesterone receptor (PR) analysed. Mammographic density using STRATUS was measured at baseline and end-of-tamoxifen-exposure. We found that different doses of tamoxifen reduced mammographic density and glandular-epithelial area in premenopausal women and associated with reduced epithelium and increased adipose tissue. High-dose tamoxifen also decreased epithelial ER and PR expressions in premenopausal women. Premenopausal women with the greatest reduction in proliferation also had the greatest epithelial reduction. In postmenopausal women, high-dose tamoxifen decreased the epithelial area with no measurable density decrease. Tamoxifen at both low and high doses influences breast tissue composition and expression of histological markers in the normal breast. Our findings connect epithelial proliferation with tissue remodelling in premenopausal women and provide novel insights to understanding biological mechanisms of primary prevention with tamoxifen.

Side effects of low-dose tamoxifen: results from a six-armed randomised controlled trial in healthy women.

BACKGROUND: Adherence to adjuvant tamoxifen therapy is suboptimal, and acceptance of tamoxifen for primary prevention is poor. Published results indicate effect of low-dose tamoxifen therapy. Using questionnaire data from a randomised controlled trial, we describe side effects of standard and low-dose tamoxifen in healthy women. METHODS: In the KARISMA trial, 1440 healthy women were randomised to 6 months of daily intake of 20, 10, 5, 2.5, 1 mg of tamoxifen or placebo. Participants completed a 48-item, five-graded Likert score symptom questionnaire at baseline and follow-up. Linear regression models were used to identify significant changes in severity levels across doses and by menopausal status. RESULTS: Out of 48 predefined symptoms, five were associated with tamoxifen exposure (hot flashes, night sweats, cold sweats, vaginal discharge and muscle cramps). When comparing these side effects in premenopausal women randomised to low doses (2.5, 5 mg) versus high doses (10, 20 mg), the mean change was 34% lower in the low-dose group. No dose-dependent difference was seen in postmenopausal women. CONCLUSIONS: Symptoms related to tamoxifen therapy are influenced by menopausal status. Low-dose tamoxifen, in contrast to high-dose, was associated with less pronounced side effects, a finding restricted to premenopausal women. Our findings give new insights which may influence future dosing strategies of tamoxifen in both the adjuvant and preventive settings. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03346200.

Topical Endoxifen for Mammographic Density Reduction-A Randomized Controlled Trial.

Although breast cancer incidence is increasing, there are few primary preventive initiatives. Tamoxifen can reduce breast cancer incidence but is rarely used for primary prevention due to adverse events and tolerance issues. We tested if endoxifen, a tamoxifen metabolite, applied directly to the skin of the breast, could reduce mammographic density, a proxy for therapy response. Ninety women were randomized to placebo, 10 and 20 mg of topical Z-endoxifen for 6 months. Mammographic density and symptoms were measured at baseline and study exit. Despite a high discontinuation rate, driven by skin rashes, we found a significant mammographic density decrease, a dose-dependent increase in the concentration of plasma Z-endoxifen but no systemic side effects. Topical application of tamoxifen metabolites has the potential to decrease breast cancer incidence without major systemic side effects. However, endoxifen may not be suitable for topical administration and is unlikely to be used for breast cancer prevention.

Time to Mammographic Density Decrease After Exposure to Tamoxifen.

Mammographic density change has proven to be a reliable proxy for tamoxifen therapy response. The primary aim of this study was to identify time to tamoxifen-induced mammographic density change. We also analyzed side effects and adherence to therapy. In all, 42 women were randomized to 10 or 20 mg of daily oral tamoxifen. Mammograms were taken at baseline, 3, 6, and 9 months. Mammographic density change was measured using the automated STRATUS tool. Adverse events were monitored through a web-based questionnaire based on the FACT-ES tool. Nine out of the 42 (21%) participants discontinued therapy due to adverse events leaving 33 women in the study. A significant decrease in density was seen after 3 months of therapy. Dose did not seem to affect density change, side effects or adherence. Given the size of the study, additional studies are needed to confirm our data.

Equal receipt of specialized palliative care in breast and prostate cancer: a register study.

PURPOSE: There are inequalities in cancer treatment. This study aimed to investigate whether receipt of specialized palliative care (SPC) is affected by typical female and male diagnoses (breast and prostate cancer), age, socioeconomic status (SES), comorbidities as measured by the Charlson Comorbidity Index (CCI), or living arrangements (home vs nursing home residence). Furthermore, we wanted to investigate if receipt of SPC affects the place of death, or correlated with emergency department visits, or hospital admissions. METHODS: All breast and prostate cancer patients who died with verified distant metastases during 2015-2019 in the Stockholm Region were included (n = 2516). We used univariable and stepwise (forward) logistic multiple regression models. RESULTS: Lower age, lower CCI score, and higher SES significantly predicted receipt of palliative care 3 months before death (p = .007-p < .0001). Patients with prostate cancer, a lower CCI score, receiving palliative care services, or living in a nursing home were admitted to a hospital or visited an emergency room less often during their last month of life (p = .01 to < .0001). Patients receiving palliative care services had a low likelihood of dying in an acute care hospital (p < .001). Those who died in a hospital were younger, had a lower CCI score, and had received less palliative care or nursing home services (p = .02- < .0001). CONCLUSION: Age, comorbidities, and nursing home residence affected the likelihood of receiving SPC. However, the diagnosis of breast versus prostate cancer did not. Emergency room visits, hospital admissions, and hospital deaths are registered less often for patients with SPC.

Patient interactive digital support for women with adjuvant endocrine therapy in order to increase compliance and quality of life.

PURPOSE: The primary aim of the study was to develop and investigate a patient interactive digital support (an app) for patients on adjuvant endocrine breast cancer treatment. Patient's interactive digital applications are a fast-growing area for research and development. In general, patients want more information and support with regard to their diagnosis, treatment and self-care. At the same time, the health care system has limited resources for follow-up. Our primary endpoints were usability of the app and if it added any value to the patients. METHODS: We designed and constructed a prototype, in dialogue with patients, containing four main modules for registration of drug compliance, performed physical exercise, self-care activities, and questions on health and quality of life. The app was then tested by patients and improved further before we completed a pilot study in which 15 patients used the app for 3 months. RESULTS: Patients perceived the app easy to use with a very high median system usability score of 88.8, range 30-100. The 15 women registered in total 4251 times, range 118 to 372. The majority of registrations concerned compliance (adherence to treatment) and physical exercise. CONCLUSION: The app was perceived easy to use and of support in every-day life of breast cancer survivors. How to best integrate electronically collected patient reported outcome measures in clinical routine needs to be further studied, and future research will show if it will be cost-effective in terms of better health outcome and less resource use.

Chronic obstructive pulmonary disease and lung cancer: access to palliative care, emergency room visits and hospital deaths.

BACKGROUND: Despite the severe symptoms experienced by dying COPD patients, specialized palliative care (SPC) services focus mainly on cancer patients. We aimed to study the access to SPC that COPD and lung cancer (LC) patients receive and how that access affects the need for acute hospital care. METHODS: A descriptive regional registry study using data acquired through VAL, the Stockholm Regional Council's central data warehouse, which covers nearly all healthcare use in the county of Stockholm. All the patients who died of COPD or LC from 2015 to 2019 were included. T-tests, chi-2 tests, and univariable and multivariable logistic regression analyses were performed on the accumulated data. RESULTS: In total, 6479 patients, (2917 with COPD and 3562 with LC) were studied. The patients with LC had more access to SPC during the last three months of life than did those with COPD (77% vs. 18%, respectively; p < .0001), whereas patients with COPD were more likely to be residents of nursing homes than those with LC (32% vs. 9%, respectively; p < .0001). Higher socioeconomic status (SES) (p < .01) and patient age < 80 years (p < .001) were associated with increased access to SPC for LC patients. Access to SPC correlated with fewer emergency room visits (p < .0001 for both COPD and LC patients) and fewer admissions to acute hospitals during the last month of life (p < .0001 for both groups). More COPD patients died in acute hospitals than lung cancer patients, (39% vs. 20%; χ2 = 287, p < .0001), with significantly lower figures for those who had access to SPC (p < .0001). CONCLUSIONS: Compared to dying COPD patients, LC patients have more access to SPC. Access to SPC reduces the need for emergency room visits and admissions to acute hospitals.

The effects of clinical and sociodemographic factors on survival, resource use and lead times in patients with high-grade gliomas: a population-based register study.

BACKGROUND: Previous studies indicate an effect of sociodemographic factors on risk for being diagnosed with, as well as on survival of cancer in general. Our primary aim was to analyse sociodemographic factors, resource use and lead times in health care after diagnosis with high grade malignant glioma (HGG) in a large population based cohort. METHODS: A register-based study using several unique high-coverage registries. All patients over the age of 18 diagnosed with HGG in the Swedish Stockholm-Gotland region between 2001 and 2013 (n = 1149) were included. RESULTS: In multivariable cox proportional hazard model of survival, older age, male sex and high tumour grade were associated with worse survival. No significant differences could be seen related to country of birth. A high disposable income was associated with better survival and fewer occasions of pre-diagnostic inpatient care. Older age and comorbidities were correlated with a significantly increased number of outpatient visits the year before HGG diagnosis. In addition, male sex, being born outside Sweden was associated to a higher number of outpatient visits the year after diagnosis in multivariable analysis. Leadtime from diagnosis (first suspicion on brain scan) to surgery showed that the oldest patients, patients with comorbidity and patients born outside Europe had to wait longer for surgery. CONCLUSIONS: Sociodemographic factors like education, income and country of birth have impact on care processes both before and after the diagnosis HGG. This needs to be acknowledged in addition to important clinical factors like age, comorbidity and tumour grade, in order to accomplish more equal cancer care.

The will to live - breast cancer patients perceptions' of palliative chemotherapy.

BACKGROUND: For women with metastatic breast cancer, late lines of chemotherapy might be beneficial but also harmful. Ongoing chemotherapy late in life increase the risk of late or absent discussions of palliative care and access to symptom relief by other options than chemotherapy. Our aim was, therefore, to investigate breast cancer patients' motives, perceptions, and experiences of late lines of palliative oncologic treatment. MATERIAL AND METHODS: A qualitative study with semi-guided face-to-face interviews with 20 women on at least their second line of palliative chemotherapy (second-eighth line). All women had breast cancer and were 40-80 years old. The interviews were analyzed by a phenomenographical approach according to seven steps, which uses a second-order perspective, i.e., how the informants experience the world. RESULTS: The categories that surrounded the decision to continue with palliative chemotherapy were: The decision, Personal motives and goals and The treatment. All women acknowledged that they knew they had incurable breast cancer and that the treatment goal was to slow down cancer growth. Fear of death was a strong motive for all women in addition to experience of new values of life, still they preferred the doctor to make the decision. Cancer symptoms, especially pain triggered death anxiety, whereas the patients patiently accepted similar side effects from the treatment. There were also external motives for treatment like wishes from family, friends, but also health care staff. CONCLUSIONS: All women knew they had disseminated breast cancer, still they expressed hopes for cure, therefore, death was more of a threat than a reality of an imminent death. None of the women had perceived there was an option to stop treatment. They felt both their families and doctors expected them to continue. Death threat was their main motive for accepting treatment.

Does palliative chemotherapy provide a palliative effect on symptoms in late palliative stages? An interview study with oncologists.

BACKGROUND: The possible chemotherapy effects on symptoms in late stages of palliative chemotherapy are seldom registered in clinical practice or investigated as primary outcomes. The aim was therefore to study physicians' opinions and experiences about chemotherapy effects on symptoms. MATERIAL AND METHODS: Thirty-five physicians (mainly oncologists) with variation as regards age, gender and experience were included in a qualitative study with semi-structured interviews. A qualitative content analysis was used for the 30-60 min long interviews. RESULTS: According to all the informants, symptoms were possible to control in successful cases but the chances reduce rapidly with the number of chemotherapy lines. Symptoms possible to control included various types of pain (bone pain, neuropathic cranial as well as meningeal nerve pain, colic pain, "liver" pain, headache and pain from cutaneous metastases); nausea and vomiting caused by obstruction; dyspnoea due to pleural effusions or bronchial obstructions. Also fatigue and B-symptoms were possible targets, as were diagnosis-specific symptom clusters (e.g., liver metastasis causing pain, nausea, tumour fever and night sweats; or head-neck cancers resulting in nerve pain, ulcerations, odour, dysphagia and impaired breathing). Some of the oncologists discussed whether the effects were related to chemotherapy treatment only or partly to premedication with steroids. Despite the claimed effects, the physicians did not keep record on symptoms, they did not evaluate them with validated instruments. CONCLUSIONS: Palliative chemotherapy has a substantial potential to reduce agonizing symptoms especially in first line treatments, but the effect is limited in late stages. The actual awareness of and knowledge about situations where the treatment has a reasonable potential, should be improved and symptoms should be monitored during treatment.

Healthcare resource use, comorbidity, treatment and clinical outcomes for patients with primary intracranial tumors: a Swedish population-based register study.

BACKGROUND: Primary intracranial tumors are relatively uncommon and heterogeneous, which make them challenging to study. We coupled data from unique Swedish population-based registries in order to deeper analyze the most common intracranical tumor types. Patient characteristics (e.g. comorbidities), care process measures like adherence to national guidelines, healthcare resource use and clinical outcome was evaluated. MATERIALS AND METHODS: A register-based study including several population-based registries for all patients living in Stockholm-Gotland, diagnosed with primary intracranial tumor between 2001 and 2013 was performed. Patient characteristics were captured and investigated in relation to survival, healthcare resource use (inpatient-, outpatient- and primary care) and treatment process. RESULTS: High-grade glioma and meningioma were the most common tumor types and most patients (76%) were above the age of 40 in the patient population (n = 3664). Older age, comorbidity (Elixhauser comorbidity index) and type of tumor (high-grade glioma) were associated with lower survival rate and increased use of healthcare resources, analyzed for patients living in Stockholm (n = 3031). The analyses of healthcare use and survival showed no differences between males and females, when stratifying by tumor types. Healthcare processes were not always consistent with existing national treatment recommendations for patients with high-grade gliomas (n = 474) with regard to specified lead times, analyzed in the Swedish Brain Tumor Registry, as also observed at the national level. CONCLUSIONS: Age, comorbidity and high-grade gliomas, but not sex, were associated with decreased survival and increased use of healthcare resources. Fewer patients than aimed for in national guidelines received care according to specified lead times. The analysis of comprehensive population-based register data can be used to improve future care processes and outcomes.

Familial adversity: association with discontinuation of adjuvant hormone therapy and breast cancer prognosis.

BACKGROUND: Many studies have examined patient-related factors affecting adjuvant hormone therapy adherence in patients with breast cancer. Our study aimed to examine associations of family-related factors with adjuvant hormone therapy discontinuation and breast cancer-specific mortality. METHODS: By cross-linking 7 Swedish health registers, we performed a cohort study that included all patients with breast cancer who initiated adjuvant hormone therapy during 2006-2019 in Sweden (N = 10 701). A group-based multitrajectory model was used to identify familial adversity groups based on 3 dimensions: material deprivation, negative family dynamics, and loss or threat of loss. Cox proportional hazard models were used to investigate associations of familial adversity with hormone therapy discontinuation and breast cancer-specific mortality. RESULTS: We identified 5 distinctive familial adversity groups among the cohort participants. Compared with women who had low familial adversity, higher risks to discontinue adjuvant hormone therapy were observed among women with material deprivation (hazard ratio [HR] = 1.31, 95% confidence interval [CI] = 1.20 to 1.43), negative family dynamics (HR = 1.16, 95% CI = 1.06 to 1.28), loss or threat of loss (HR = 1.15, 95% CI = 1.00 to 1.32), or high familial adversity (HR = 1.53, 95% CI = 1.40 to 1.68). Furthermore, women with material deprivation (HR = 1.37, 95% CI = 1.05 to 1.79), negative family dynamics (HR = 1.41, 95% CI = 1.01 to 1.97), or high adversity (HR = 1.67, 95% CI = 1.26 to 2.23) were at higher risk of dying from breast cancer. CONCLUSION: Familial adversity is associated with a higher risk of adjuvant hormone therapy discontinuation and breast cancer-specific mortality. Family-related factors identified in our study may help identify high-risk patients for interventions to prevent treatment discontinuation and subsequently improve breast cancer outcomes.

Determinants and Effectiveness of Extending the Duration of Adjuvant Hormone Therapy beyond 5 Years in Patients with Breast Cancer.

Clinical guidelines have recommended patients with high-risk breast cancer to extend adjuvant hormone therapy beyond 5 years. However, the prevalence, predictors, and outcomes of extended adjuvant hormone therapy in the real world remain unknown. By linking six Swedish health registries, we prospectively followed 13,168 patients with breast cancer (2005-2020) from their first prescription of tamoxifen or aromatase inhibitors and categorized them as extending or not extending adjuvant hormone therapy. Cox regression analysis was used to investigate whether extended therapy was associated with breast cancer outcomes. Among patients with breast cancer who were recommended to extend adjuvant hormone therapy by the national guidelines, the proportion of women who extended therapy increased 5 folds during the past 10 years, reaching 80.9% during 2018 to 2020. Patients were more likely to extend therapy after completing 5-year adjuvant hormone therapy if they were young [40 vs. ≥65 years: OR, 1.71; 95% confidence interval (CI), 1.13-2.58], had positive lymph nodes (OR, 2.25; 95% CI, 1.85-2.73), had high tumor grade (grade 3 vs. 1: OR, 1.79; 95% CI, 1.34-2.39), received chemotherapy (OR, 5.22; 95% CI, 4.19-6.50), had first-degree relatives who died from breast cancer (OR, 1.84; 95% CI, 1.21-2.81), or had a high income (OR, 1.23; 95% CI, 1.01-1.49). Extended use of adjuvant hormone therapy was statistically significantly associated with improved disease-free survival (HR, 0.72; 95 CI%, 0.55-0.95). This study provides real-world evidence showing the use and improved breast cancer outcomes of extended adjuvant hormone therapy beyond 5 years. SIGNIFICANCE: The proportion of patients with breast cancer extending adjuvant hormone therapy beyond 5 years has increased dramatically in recent years, which is associated with improved patient outcomes.

'Palliative-D'-Vitamin D Supplementation to Palliative Cancer Patients: A Double Blind, Randomized Placebo-Controlled Multicenter Trial.

The aim of the 'Palliative-D' study was to test the hypothesis that correction of vitamin D deficiency reduces opioid use in cancer patients admitted to palliative care. A multicenter randomized, placebo-controlled, double-blind trial in three home-based palliative care facilities in Sweden was performed. Patients with advanced cancer and 25-hydroxyvitamin D < 50 nmol/L were randomized to vitamin D3 4000 IU/day or placebo for 12 weeks. The primary endpoint was the difference of long-acting opioid use (fentanyl ug/h) between the groups during 12 weeks, based on four time points. Secondary outcomes included changes in antibiotic use, fatigue and Quality of Life (QoL). A total of 244 patients were randomized, and 150 patients completed the 12 weeks. The major reason for drop-out was death due to cancer. The vitamin D-group had a significantly smaller increase of opioid doses compared to the placebo-group; beta coefficient -0.56 (p = 0.03), i.e., 0.56 µg less fentanyl/h per week with vitamin D treatment. Vitamin D-reduced fatigue assessed with ESAS was -1.1 points after 12 weeks (p < 0.01). Antibiotic use or QoL did not differ significantly between the groups. The treatment was safe and well-tolerated. In conclusion, correction of vitamin D deficiency may have positive effects on opioid use and fatigue in palliative cancer patients, but only in those with a survival time more than 12 weeks.

The Impact of Integrated Home Palliative Care Services on Resource Use and Place of Death.

Background: Specialized home-based palliative care (HPC) services aim at reducing the number of visits to emergency departments (EDs) and hospitalizations at end of life. In addition, it offers patients the possibility to die at home. Objective: To investigate whether the last years' expansion of palliative care in Stockholm County, Sweden, reduced the health care resource use and/or increased the number of patients who died at home. Design: This is a population-based study of all registered 2780 patients referred to HPC in 2015 in the Stockholm region. The majority of the patients (2087) had cancer, but 693 patients had chronic medical illness, most often cardiovascular and pulmonary diseases. Results: HPC reduced visits to the ED and hospital admissions by 51% and 41%, respectively. The number of hospital admissions to the departments of oncology, medicine, and surgery was reduced, whereas admissions to palliative care units increased. For the 1773 patients alive after 90 days with HPC, the number of days spent in hospital reduced from 19,628 before HPC to 13,743 (30%) days with HPC. The most common place of death was at a specialized palliative care unit (48%), whereas 36% died at home. Conclusions: HPC reduced emergency health care resource use for the majority of patients, despite patients having progressing disease. To improve the quality of end-of-life care, we need to make early integration of palliative care available for a larger number of patients. In addition, we have to improve care pathways, especially for patients with gastrointestinal and lung cancer, who continued to be frequently admitted to hospital.

Breast Cancer Patients' Preferences for Truth Versus Hope Are Dynamic and Change During Late Lines of Palliative Chemotherapy.

CONTEXT: Women with metastatic breast cancer often receive many lines of palliative chemotherapy, which might be beneficial but also harmful. Still, little is known about the patients' perception of the patient-doctor communication regarding late lines of noncurative treatment. OBJECTIVES: Our aim was to explore breast cancer patients' preferences and perceptions of patient-doctor communication regarding continuous late lines of palliative chemotherapy. PATIENTS AND METHODS: A qualitative study was conducted with semiguided face-to-face interviews with 20 women, 40-80 years old, on at least their second line of palliative chemotherapy (second to eighth line). We used a qualitative conventional content analysis. RESULTS: All women knew they had incurable breast cancer but expressed hope for cure. Patients' definition of a good compassionate doctor was one who gives positive news and leaves room for hope. Ongoing chemotherapy, positive news from the doctors, and support from relatives encouraged hope. The women often expressed they accepted chemotherapy to please their doctor and relatives. The informants appreciated the doctor to be honest, but within positive limits. Over time, they stopped asking questions afraid of getting bad news, and left more and more treatment decisions to the doctor. CONCLUSIONS: The women's preferences for truth versus hope in patient-doctor communication changed over time, which increase the risk for continuous late lines of palliative chemotherapy by common collusion. Doctors need to individualize information, help patients make sense of their life, and allow hope to endure without further chemotherapy.

How to treat male breast cancer.

The prevalence for breast cancer in males in Europe is estimated to be 1 or less per 100,000. Male breast cancer has a peak incidence at the age of 71 years. There are no randomized data giving information on the optimal therapy for male breast cancer patients, thereby limiting firmer conclusions. The preferred primary surgical therapy is modified radical/simple mastectomy, but breast-conserving surgery has also been used in males. Post-operative radiotherapy should be used on a more routine basis; as males have shorter breast-anatomical distances and males are diagnosed at a later stage compared with females. The so far preferred adjuvant therapy modality has been tamoxifen for patients with endocrine responsive disease. The use of aromatase inhibitors in males is more controversial, since they may not deplete the estradiol levels sufficiently. Different chemotherapy regimens have been used in the adjuvant and metastatic setting. The use of adjuvant therapy has in institutional and review comparisons been demonstrated to result in an improved outcome.

Vitamin D supplementation to palliative cancer patients shows positive effects on pain and infections-Results from a matched case-control study.

BACKGROUND: We previously showed an association between low vitamin D levels and high opioid doses to alleviate pain in palliative cancer patients. The aim of this case-controlled study was to investigate if vitamin D supplementation could improve pain management, quality of life (QoL) and decrease infections in palliative cancer patients. METHODS: Thirty-nine palliative cancer patients with levels of 25-hydroxyvitamin D < 75 nmol/L were supplemented with vitamin D 4000 IE/day, and were compared to 39 untreated, matched "control"-patients from a previous study at the same ward. Opioid doses, antibiotic consumption and QoL-scores measured with the Edmonton Symptom Assessment Scale (ESAS) were monitored. The primary endpoint was the change from baseline after 1 and 3 months compared between the groups using linear regression with adjustment for a potential cofounding factor. RESULTS: After 1 month the vitamin D treated group had a significantly decreased fentanyl dose compared to the untreated group with a difference of 46 µg/h; 95% CI 24-78, which increased further at 3 months to 91 µg/h; 95% CI 56-140 µg/h. The ESAS QoL-score improved in the Vitamin D group the first month; -1.4; 95% CI -2.6 - (-0.21). The vitamin D-treated group had significantly lower consumption of antibiotics after 3 months compared to the untreated group, the difference was -26%; 95%CI -0.41%-(-0.12%). Vitamin D was well tolerated by all patients and no adverse events were reported. CONCLUSION: Vitamin D supplementation to palliative cancer patients is safe and improvement in pain management is noted as early as 1 month after treatment. Decreased infections are noted 3 months after vitamin D treatment. The results from this pilot-study have been used for the power-calculation of a future randomized, placebo-controlled, double-blind study called "Palliative-D" that will start in Nov 2017 and will include 254 palliative cancer patients.
