RESUMEN

PURPOSE: To examine health-related quality of life (HRQoL) and supportive care needs among young adult (YA) cancer survivors up to 3 years post-diagnosis. METHODS: A national cohort of individuals diagnosed at 18-39 years with breast, cervical, ovarian, or testicular cancer, lymphoma or brain tumor was approached with surveys at 1.5 (n = 1010, response rate 67%) and 3 (n = 722) years post-diagnosis. HRQoL was measured using the EORTC QLQ-C30. Scores were dichotomized using cut-off scores to predict supportive care needs in the Supportive Care Needs Survey-Long Form 59 (SCNS-LF59). Swedish cancer quality registers provided clinical data. Factors predicting need of support at 1.5 and 3 years post-diagnosis were identified using logistic regression. RESULTS: HRQoL improvements over time were trivial to small. At both time points, a majority of respondents rated HRQoL levels indicating supportive care needs. At 1.5 years post-diagnosis, the risk of having support needs was lower among survivors with testicular cancer (compared to lymphoma) or university-level education, and higher among those on treatment (predominantly endocrine therapy). At 3 years post-diagnosis, when controlling for previous HRQoL scores, most correlations persisted, and poor self-rated household economy and chronic health conditions were additionally associated with supportive care needs. CONCLUSION: A majority of YAs diagnosed with cancer rate HRQoL at levels indicating support needs up to 3 years post-diagnosis. Testicular cancer survivors are at lower risk of having support needs. Concurrent health conditions and poor finances are linked to lower HRQoL. More efforts are needed to provide adequate, age-appropriate support to YA cancer survivors.

RESUMEN

BACKGROUND: Cancer treatment during reproductive ages may negatively impact fertility and there is a need of firm knowledge about the prevalence and predictors of fertility-related distress. The aim was to examine fertility-related distress in a population-based sample of young women and men recently treated for cancer and to identify predictors for this outcome. MATERIAL AND METHODS: This nationwide cohort study included 1010 individuals (694 women and 316 men), mean age 34.5 ± 4.9 and 32.1 ± 5.5, respectively, diagnosed with breast, cervical, ovarian, testicular cancers, brain tumors or lymphoma at ages 18-39 in Sweden. Participants completed a survey 1.5-year post-diagnosis to assess fertility-related distress (RCAC), emotional distress (HADS) and self-efficacy, as well as sociodemographic and clinical factors and fertility preservation. Logistic regression was used to examine associations between explanatory factors and high fertility-related distress (RCAC subscale mean >4). RESULTS: Many participants (69% of women and 47% of men) had previous children and about half reported a wish for future children. High fertility-related distress was more prevalent among women (54%) than men (27%), and women were more likely than men to report distress concerning all but one RCAC dimension after adjustment for sociodemographic factors. Use of fertility preservation was unevenly distributed (15% of women and 71% of men) and was not associated with decreased fertility-related distress. In multivariable logistic regression models, a wish for future children, being single, not having previous children, symptoms of anxiety and low self-efficacy regarding one's ability to handle threats of infertility were associated with high fertility-related distress. CONCLUSION: This nationwide study found a high prevalence of fertility-related distress in young women and men recently treated for cancer and identified sociodemographic and psychological predictors. Fertility preservation was not found to act as a buffer against fertility-related distress, indicating the continuous need to identify strategies to alleviate fertility distress following cancer.

RESUMEN

PURPOSE: Pseudoprogression (PsP) remains an elusive and clinically important, yet ill-defined, phenomena that, generally, involves a period of early radiographic progression (enhancement) followed by a period of radiographic stability or regression. In the current study, we utilized data from the control arm of a phase III clinical trial in newly-diagnosed glioblastoma to explore imaging characteristics of "clinically-defined PsP", or early radiographic progression (PFS < 6 months from chemoradiation) followed by a long post-progression residual overall survival (ROS > 12 months). METHODS: One hundred sixty-nine patients with newly-diagnosed GBM from the control arm of the AVAglio trial (NCT00943826) who presented with early radiographic progressive disease (PD) (< 6 months) were included. Clinical characteristics, topographical patterns, and radiomic features were compared between newly-diagnosed GBM exhibiting early PD and early death (< 12-month ROS, "true PD") with those exhibiting early PD and a long residual survival (> 12-month ROS, "clinically-defined PsP"). RESULTS: "Clinically-defined PsP" occurred to 38.5% of patients with early PD, and was more associated with MGMT methylation (P = 0.02), younger age (P = 0.003), better neurological performance (P = 0.01), and lower contrast-enhancing tumor volume (P = 0.002) at baseline. GBM showing "true PD" occurred more frequently in the right internal capsule, thalamus, lentiform nucleus, and temporal lobe than those with "clinical PsP". Radiomic analysis predicted "clinical PsP" with > 70% accuracy on the validation dataset. CONCLUSION: Patients with early PD that eventually exhibit "clinically-defined PsP" have distinct clinical, molecular, and MRI characteristics. This information may be useful for treating clinicians to better understand the potential risks and outcome in patients exhibiting early radiographic changes following chemoradiation.

RESUMEN

BACKGROUND: Self-reported sex problems among women diagnosed with reproductive and nonreproductive cancers before the age of 40 are not fully understood. This study aimed to determine sexual dysfunction in young women following a cancer diagnosis in relation to women of the general population. Furthermore, to identify factors associated with sexual dysfunction in women diagnosed with cancer. MATERIALS AND METHODS: A population-based cross-sectional study with 694 young women was conducted 1.5 years after being diagnosed with cancer (response rate 72%). Potential participants were identified in national quality registries covering breast and gynecological cancer, lymphoma and brain tumors. The women with cancer were compared to a group of women drawn from the general population (N = 493). Sexual activity and function were assessed with the PROMIS® SexFS. Logistic regression was used to assess differences between women with cancer and the comparison group, and to identify factors associated with sexual dysfunction. RESULTS: The majority of the women with cancer (83%) as well as the women from the comparison group (87%) reported having had sex the last month (partner sex and/or masturbation). More than 60% of the women with cancer (all diagnoses) reported sexual dysfunction in at least one of the measured domains. The women with cancer reported statistically significantly more problems than women of the comparison group across domains such as decreased interest in having sex, and vaginal and vulvar discomfort. Women with gynecological or breast cancer and those receiving more intense treatment were at particular high risk of sexual dysfunction (≥2 domains). Concurrent emotional distress and body image disturbance were associated with more dysfunction. CONCLUSION: The results underscore the need to routinely assess sexual health in clinical care and follow-up. Based on the results, development of interventions to support women to cope with cancer-related sexual dysfunction is recommended.

RESUMEN

OBJECTIVES: Seizures as presenting symptom of glioblastoma (GBM) are known to predict prolonged survival, whereas the clinical impact of other initial symptoms is less known. Our main objective was to evaluate the influence of different presenting symptoms on survival in a clinical setting. We also assessed lead times, tumour size and localization. METHODS: Medical records of 189 GBM patients were reviewed regarding the first medical appointment, presenting symptom/s, date of diagnostic radiology and survival. Tumour size, localization and treatment data were retrieved. Overall survival was calculated using Kaplan-Meier and Mann-Whitney U test. Cox regression was used for risk estimation. RESULTS: Cognitive impairment as the initial symptom was often misinterpreted in primary health care leading to a delayed diagnosis. Initial global symptoms (66% of all patients) were associated with reduced survival compared to no global symptoms (median 8.4 months vs. 12.6 months). Those with the most common cognitive dysfunctions: change of behaviour, memory impairment and/or disorientation had a reduced median survival to 6.4 months. In contrast, seizures (32%) were associated with longer survival (median 11.2 months vs. 8.3 months). Global symptoms were associated with larger tumours than seizures, but tumour size had no linear association with survival. The setting of the first medical appointment was evenly distributed between primary health care and emergency units. CONCLUSION: Patients with GBM presenting with cognitive symptoms are challenging to identify, have larger tumours and reduced survival. In contrast, epileptic seizures as the first symptom are associated with longer survival and smaller tumours.

RESUMEN

BACKGROUND: Low-grade glioma (LGG) is a relatively rare type of brain tumour. The use of antidepressant, sedative and anti-epileptic drugs can reflect the burden of the disease. While epilepsy is well-described in patients with LGG, less is known about depression and anxiety. METHODS: We used nationwide registers to study the use (dispense) of antidepressants, sedatives, and anti-epileptic drugs (AEDs) before and after histopathological LGG diagnosis (WHO grade II). A total of 485 adult patients with a first-time diagnosis and a matched control cohort (n = 2412) were included. Patterns of use were analysed from one year prior to until one year following index date (date of surgery). Logistic regression analysis identified predictors for postoperative use. RESULTS: At one year before index date, patients were dispensed AEDs 4 times more than controls, while antidepressants and sedatives were similar. Sedatives and AED peaked shortly after index date at 25 and 69%, respectively. AEDs then stabilized while sedatives decreased rapidly. For antidepressants, a delayed increase was seen after index date, stabilizing at 12%. At one year after index date, the use of antidepressants, sedatives, and AEDs among patients was 2, 3, and 26 times higher, respectively, compared to controls. Predictor for use of AEDs and sedatives at one year following index was previous use and/or a related diagnosis. Female sex and later index year were additional predictors for antidepressants. CONCLUSIONS: Use of antidepressants, sedatives and AEDs is elevated following diagnosis of LGG. Antidepressants were more commonly dispensed to female patients and in recent years.

RESUMEN

BACKGROUND: Infertility is a well-known sequela of cancer treatment. Despite guidelines recommending early discussions about risk of fertility impairment and fertility preservation options, not all patients of reproductive age receive such information. AIMS: This study aimed to investigate young adult cancer patients' receipt of fertility-related information and use of fertility preservation, and to identify sociodemographic and clinical factors associated with receipt of information. MATERIALS AND METHODS: A population-based cross-sectional survey study was conducted with 1010 young adults with cancer in Sweden (response rate 67%). The inclusion criteria were: a previous diagnosis of breast cancer, cervical cancer, ovarian cancer, brain tumor, lymphoma or testicular cancer between 2016 and 2017, at an age between 18 and 39 years. Data were analyzed using logistic regression models. RESULTS: A majority of men (81%) and women (78%) reported having received information about the potential impact of cancer/treatment on their fertility. A higher percentage of men than women reported being informed about fertility preservation (84% men vs. 40% women, p < .001) and using gamete or gonadal cryopreservation (71% men vs. 15% women, p < .001). Patients with brain tumors and patients without a pretreatment desire for children were less likely to report being informed about potential impact on their fertility and about fertility preservation. In addition, being born outside Sweden was negatively associated with reported receipt of information about impact of cancer treatment on fertility. Among women, older age (>35 years), non-heterosexuality and being a parent were additional factors negatively associated with reported receipt of information about fertility preservation. CONCLUSION: There is room for improvement in the equal provision of information about fertility issues to young adult cancer patients.

RESUMEN

BACKGROUND: Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) copy number alterations and unbalanced gene recombination events have been reported to occur in breast cancer. Importantly, LRIG1 loss was recently shown to predict early and late relapse in stage I-II breast cancer. METHODS: We developed droplet digital PCR (ddPCR) assays for the determination of relative LRIG1 copy numbers and used these assays to analyze LRIG1 in twelve healthy individuals, 34 breast tumor samples previously analyzed by fluorescence in situ hybridization (FISH), and 423 breast tumor cytosols. RESULTS: Four of the LRIG1/reference gene assays were found to be precise and robust, showing copy number ratios close to 1 (mean, 0.984; standard deviation, +/- 0.031) among the healthy control population. The correlation between the ddPCR assays and previous FISH results was low, possibly because of the different normalization strategies used. One in 34 breast tumors (2.9%) showed an unbalanced LRIG1 recombination event. LRIG1 copy number ratios were associated with the breast cancer subtype, steroid receptor status, ERBB2 status, tumor grade, and nodal status. Both LRIG1 loss and gain were associated with unfavorable metastasis-free survival; however, they did not remain significant prognostic factors after adjustment for common risk factors in the Cox regression analysis. Furthermore, LRIG1 loss was not significantly associated with survival in stage I and II cases. CONCLUSIONS: Although LRIG1 gene aberrations may be important determinants of breast cancer biology, and prognostic markers, the results of this study do not verify an important role for LRIG1 copy number analyses in predicting the risk of relapse in early-stage breast cancer.

RESUMEN

OBJECTIVE: To investigate outcomes after surgery for rare brain tumors using the Swedish Brain Tumor Registry (SBTR). METHODS: This is a nationwide study of patient in the SBTR, validated in the Surveillance, Epidemiology, and End Results (SEER) registries. We included all adults diagnosed 2009-2015 with a rare brain tumor entity (n = 216), defined as ependymoma (EP, n = 64), subependymoma (SUBEP, n = 21), ganglioglioma (GGL, n = 54), pilocytic astrocytoma (PA, n = 56) and primitive neuroectodermal tumor (PNET, n = 21). We analyzed symptomatology, tumor characteristics and outcomes. RESULTS: Mean age was 38.3 ± 17.2 years in GGL, 36.2 ± 16.9 in PA, 37.0 ± 19.1 in PNET, 51.7 ± 16.3 in EP and 49.8 ± 14.3 in SUBEP. The most common symptom was focal deficit (39.6-71.4%), and this symptom was most common in GGL patients with 64.2% of GGL presenting with seizures. Most patients had no or little restriction in activity before surgery (Performance Status 0-1), although up to 15.0% of PNET patients had a performance status of 4. Gross total resection was achieved in most (> 50%) tumor categories. Incidence of new deficits was 11.1-34.4%. In terms of postoperative complications, 0-4.8% had a hematoma of any kind, 1.9-15.6% an infection, 0-7.8% a venous thromboembolism and 3.7-10.9% experienced a complication requiring reoperation. There were 3 deaths within 30-days of surgery, and a 1-year mortality of 0-14.3%. CONCLUSION: We have provided benchmarks for the current symptomatology, tumor characteristics and outcomes after surgery for rare brain tumors as collected by the SBTR and validated our results in an independent registry. These results may aid in clinical decision making and advising patients.

RESUMEN

BACKGROUND: Despite aspirations to achieve equality in healthcare we know that socioeconomic differences exist and may affect treatment and patient outcome, also in serious diseases such as cancer. We investigated disparities in neurosurgical care and outcome for patients with low-grade glioma (LGG). METHODS: In this nationwide registry-based study, patients who had undergone surgery for LGG during 2005-2015 were identified (n = 547) through the Swedish Brain Tumor Registry. We linked data to multiple national registries with individual level data on income, education and comorbidity and analyzed the association of disease characteristics, surgical management and outcome, with levels of income, education and sex. RESULTS: Patients with either low income, low education or female gender showed worse pre-operative performance status. Patients with low income or education also had more comorbidities and those with low education endured longer waiting times for surgery. Median time from radiological imaging to surgery was 51 days (Q1-3 27-191) for patients with low education, compared to 32 days (Q1-3 20-80) for patients with high education (p = 0.006). Differences in waiting time over educational levels remained significant after stratification for age, comorbidity, preoperative performance status, and tumor size. Overall survival was better for patients with high income or high education, but income- and education-related survival differences were not significant after adjustment for age and comorbidity. The type of surgical procedure or complications did not differ over socioeconomic groups or sex. CONCLUSION: The neurosurgical care for LGG in Sweden, a society with universal healthcare, displays differences that can be related to socioeconomic factors.

RESUMEN

PURPOSE: The survival of esophageal and gastric cancer patients treated with chemotherapy is rarely assessed outside of clinical trials. Therefore, we compared the effectiveness of various curative or palliative chemotherapy regimens on the survival of esophageal and gastric cancer patients in a "real world" clinical setting. METHODS: We identified a cohort of 966 incident esophageal and gastric cancer patients in Stockholm/Gotland County (a low-risk Western population) during 2008-2013. Patients who received chemotherapy with curative intention (n = 279) and palliative intention (n = 182) were analyzed separately. Using Cox proportional hazards regression models, we estimated hazard ratios (HRs) with 95% confidence intervals (CIs) and adjusted for the potential confounding factors: age, sex, TNM stage, radiotherapy, comorbidity, marital status, education, income, and country of birth. RESULTS: In esophageal cancer patients with curative treatment intention, we observed a higher hazard for death among patients who received carboplatin-fluorouracil compared to patients who received cisplatin-fluorouracil, corresponding to a HR of 2.18 (95% CI 1.09-4.37). Conversely, in patients with cancer in the gastroesophageal junction who had a curative treatment intention at diagnosis, we observed a reduced hazard for death among those who received fluorouracil-oxaliplatin, compared to patients who received cisplatin-fluorouracil (HR 0.28; 95% CI 0.08-0.96). CONCLUSION: Among patients with esophageal cancer who received treatment with curative intention, cisplatin-fluorouracil was associated with better survival compared to carboplatin-fluorouracil, while patients with gastroesophageal junction cancer who were treated with cisplatin-fluorouracil had worse survival compared to fluorouracil-oxaliplatin.

RESUMEN

Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) is a tumor suppressor and a negative regulator of several receptor tyrosine kinases. The molecular mechanisms by which LRIG1 mediates its tumor suppressor effects and regulates receptor tyrosine kinases remain incompletely understood. Here, we performed a yeast two-hybrid screen to identify novel LRIG1-interacting proteins and mined data from the BioPlex (biophysical interactions of ORFeome-based complexes) protein interaction data repository. The putative LRIG1 interactors identified in the screen were functionally evaluated using a triple co-transfection system in which HEK293 cells were co-transfected with platelet-derived growth factor receptor α, LRIG1, and shRNAs against the identified LRIG1 interactors. The effects of the shRNAs on the ability of LRIG1 to down-regulate platelet-derived growth factor receptor α expression were evaluated. On the basis of these results, we present an LRIG1 protein interaction network with many newly identified components. The network contains the apparently functionally important LRIG1-interacting proteins RAB4A, PON2, GAL3ST1, ZBTB16, LRIG2, CNPY3, HLA-DRA, GML, CNPY4, LRRC40, and LRIG3, together with GLRX3, PTPRK, and other proteins. In silico analyses of The Cancer Genome Atlas data sets revealed consistent correlations between the expression of the transcripts encoding LRIG1 and its interactors ZBTB16 and PTPRK and inverse correlations between the transcripts encoding LRIG1 and GLRX3. We further studied the LRIG1 function-promoting paraoxonase PON2 and found that it co-localized with LRIG1 in LRIG1-transfected cells. The proposed LRIG1 protein interaction network will provide leads for future studies aiming to understand the molecular functions of LRIG1 and the regulation of growth factor signaling.

RESUMEN

Mutations in leucine-rich-repeats and immunoglobulin-like-domains 2 (LRIG2) or in heparanase 2 (HPSE2) cause urofacial syndrome, a devastating autosomal recessive disease of functional bladder outlet obstruction. It has been speculated that urofacial syndrome has a neural basis, but it is unknown whether defects in urinary bladder innervation are present. We hypothesized that urofacial syndrome features a peripheral neuropathy of the bladder. Mice with homozygous targeted Lrig2 mutations had urinary defects resembling those found in urofacial syndrome. There was no anatomical blockage of the outflow tract, consistent with a functional bladder outlet obstruction. Transcriptome analysis revealed differential expression of 12 known transcripts in addition to Lrig2, including 8 with established roles in neurobiology. Mice with homozygous mutations in either Lrig2 or Hpse2 had increased nerve density within the body of the urinary bladder and decreased nerve density around the urinary outflow tract. In a sample of 155 children with chronic kidney disease and urinary symptoms, we discovered novel homozygous missense LRIG2 variants that were predicted to be pathogenic in 2 individuals with non-syndromic bladder outlet obstruction. These observations provide evidence that a peripheral neuropathy is central to the pathobiology of functional bladder outlet obstruction in urofacial syndrome, and emphasize the importance of LRIG2 and heparanase 2 for nerve patterning in the urinary tract.

RESUMEN

BACKGROUND: Surgery is the main treatment modality for intracranial meningiomas, but data on short-term surgical outcome are limited. The aim of this Swedish nationwide registry-based study was to benchmark the 30-day complication rate in a cohort of meningioma patients using data from the Swedish brain tumor registry (SBTR). Furthermore, we investigated outcomes for asymptomatic patients. METHODS: Data were collected from the SBTR for all adults with histopathologically verified intracranial meningioma between 2009 and 2015. Patient symptoms, tumor characteristics, and complications within 30 days postoperatively were analyzed. RESULTS: In total, 2324 patients, with a mean age of 58.7 years (SD 13.5), underwent surgery for intracranial meningioma and 14.1% of the patients were asymptomatic before the intervention. The most common symptom prior to treatment was focal deficit, which occurred in 1450 patients (62.4%). Moreover, within 30 days after surgery, 344 patients (14.8%) developed new neurological deficits and new-onset seizures occurred in 105 patients (4.5%), while 8.3% of asymptomatic patients developed neurological deficit and 3.7% new-onset seizures. Due to complications, reoperations were performed in 120 patients (5.2%). The postoperative 30-day mortality in the whole cohort was 1.5%. CONCLUSION: This study benchmarks the 30-day complication rate after meningioma surgery and provides outcome data in the highly relevant group of asymptomatic patients using data from the Swedish brain tumor registry. Since surgical decision-making is a careful consideration of short-term risk versus long-term benefit, this information may be useful for both caregivers and patients.

RESUMEN

BACKGROUND: Access to and advice on Complementary and Alternative Medicine (CAM) are uncommon within Swedish conventional cancer care and little is known about cancer patients' own use of CAM. The aim of this cross-sectional study was to explore Swedish cancer patients´ patterns of CAM use, their experiences and preferences. METHODS: Questionnaires were distributed consecutively to 1297 cancer patients at a university hospital's out-patient oncology units. The response rate was 58% (n = 755). Descriptive statistics were used to analyze the survey data. A logistic regression model was used to investigate the association between CAM use and gender, age and level of education. Open-ended responses were analyzed, using qualitative content analysis. RESULTS: Lifetime CAM use was reported by 34% (n = 256), and 26% (n = 198) used CAM after cancer diagnosis. Being female, younger and having higher education predicted CAM use. Most commonly used methods were natural products including vitamins and minerals and relaxation. Main reasons for CAM use were improvement of physical, general and emotional wellbeing and increasing the body's ability to fight cancer. Satisfaction with CAM usage was generally high. Reported adverse effects were few and mild; 54% of users spent < 50 Euro a month on CAM. One third had discussed their CAM use with cancer care providers. More than half of all participants thought that cancer care providers should be able to discuss (58%) and to consider (54%) use of CAM modalities in cancer care. CONCLUSIONS: Despite limited access and advice within conventional cancer care, one fourth of Swedish cancer patients use CAM. The insufficient patient-provider dialogue diverges with most patients' wish for professional guidance in their decisions and integration of CAM modalities in conventional cancer care. Concurrent and multimodal CAM use implies challenges and possibilities for cancer care that need to be considered.

RESUMEN

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.

RESUMEN

INTRODUCTION: Several supportive care strategies are described in Swedish legislation and policy documents, such as the National Cancer Strategy and the Patient act. No previous systematic evaluation from a patient perspective has been performed. The aim of this study was to evaluate how these supportive care strategies are experienced by patients treated for cancer in the Stockholm-Gotland region. MATERIAL AND METHODS: In this cross-sectional study, we identified patients (diagnosed with gynaecological, haematological, upper gastrointestinal and head and neck cancer during 2014) from the Swedish Cancer Register. The European Organization of Research and Treatment of Cancer, EORTC, Quality of Life Questionnaires, QLQ-C30, Information QLQ-INFO25 and a study-specific questionnaire was used to collect data during follow-up after cancer treatment. We collected data on 869 cancer patients' perception of availability and access to supportive care strategies and how they were experienced. RESULTS: Among the supportive care strategies suggested in the legislation and policy documents, just over half of the patients (n = 393, 53%) reported that they had access to a contact nurse, while 43% (n = 312) had received an individual written care plan and 16% (n= 137) had been referred to palliative care. Only 29% (n = 218) of the patients reported that they had received information about patient advocacy groups and 8% (n= 62) on medical second opinions from their cancer care team. DISCUSSION: The supportive care strategies suggested in Swedish legislation and policy documents may be useful but are only available for some patients. The implementation goals for the National Cancer Strategy and the Swedish Patient act have not been reached.

RESUMEN

BACKGROUND: Sweden's national cancer strategy points out several areas of cancer care that need improvements. Among them the need for supportive care resources to be accessible through the entire cancer trajectory and the reduction of socioeconomic inequalities. The aim of this study was to compare the patient-reported access to supportive care in the Stockholm-Gotland region between patients diagnosed in 2014 and 2016. The aim was also to describe how socioeconomic and other demographic factors impact access to supportive care. MATERIAL AND METHODS: All patients with gynaecological, head and neck, haematological and upper gastrointestinal cancers diagnosed in the Stockholm-Gotland regions were identified through the Swedish Cancer Registries. Data were collected via a questionnaire on demographic, socioeconomic factors and patients' perception (n = 1872) of access to supportive care. Data were summarized using descriptive statistics and logistic regression was used for relevant variables. RESULTS: Access to some supportive care resources, such as contact nurses (CNs) and individual written care plans (IWCPs) had significantly improved from 2014 to 2016. The proportion of patients that had received information about patient advocacy groups (PAGs) had also improved but remained on a relatively low level (29 and 35%, respectively). The proportion of patients being refereed to palliative care (PC) did not change between 2014 and 2016. In total, 10% of the patients reported to having received information on second medical opinion (SMO). Patients that had undergone multimodality cancer treatment were more likely to report access to supportive care, and those with lower education levels were more likely to have access to CNs and IWCPs. CONCLUSION: Access to some of the supportive care resources have shown improvements in the Stockholm-Gotland region but further efforts are required, especially regarding access to PC, information about PAGs and SMOs.

RESUMEN

BACKGROUND: Geographic cancer health disparities have been reported in Sweden. The disparities are not fully understood, but may be attributed to differences in exposure to risk factors as well as differences in health care, socioeconomics and demography. The aim of this study was to describe the new nationwide population based RISK North database and its potential by analysing health disparities in colorectal cancer between Northern and Southern Sweden. METHODS: Cancer-specific data from the National Cancer Quality Registers for colorectal, gastric and oesophageal cancer and brain tumours were linked to several nationwide registers hereby creating a new database - RISK North. To exemplify the potential of RISK North, we analyzed differences in colorectal cancer incidence, mortality and survival in relation to gender, age, cohabitation and education between Northern and Southern Sweden 2007-2013. RESULTS: In colon cancer, the age-adjusted incidence per 100.000 was lower in Northern than Southern Sweden, 35.9 in the North vs. 41.1 in the South (p < .01); mortality rates were 11.0 vs. 12.2 (p < .01). For rectal cancer, incidence rates were 17.6 vs. 19.7 (p < .01) and mortality rates 5.33 vs. 5.89 (p = .07), respectively. The largest difference in incidence was demonstrated for colon cancer among individuals >79 years old (190. vs. 237, i.e., ∼20%). Survival in colon cancer was higher in Southern Sweden, HR 0.92 (0.87-0.98) adjusted for age, gender, co-habiting, education and m-stage at diagnosis. No difference in survival was seen for rectal cancer. CONCLUSIONS: The new RISK North database enabled analysis of cancer disparities between Northern and Southern Sweden. The incidence of colorectal cancer were lower in the North of Sweden whereas colon cancer survival was higher in the South. These differences can be further analysed utilising the RISK North database.

RESUMEN

Patients with glioma present with complex palliative care needs throughout their disease trajectory. The life-limiting nature of gliomas and the presence of specific symptoms related to neurological deterioration necessitate an appropriate and early palliative care approach. The multidisciplinary palliative care task force of the European Association of Neuro-Oncology did a systematic review of the available scientific literature to formulate the best possible evidence-based recommendations for the palliative care of adult patients with glioma, with the aim to reduce symptom burden and improve the quality of life of patients and their caregivers, particularly in the end-of-life phase. When recommendations could not be made because of the scarcity of evidence, the task force either used evidence from studies of patients with systemic cancer or formulated expert opinion. Areas of palliative care that currently lack evidence and thus deserve attention for further research are fatigue, disorders of behaviour and mood, interventions for the needs of caregivers, and timing of advance care planning.
