Abstract
Abstract
Background
Cardiovascular secondary preventive strategies need improvement. The proportion of patients reaching guideline recommended treatment targets are low.
Purpose
We investigated if nurse-led, telephone-based follow-up including medical titration was superior to usual care in controlling blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) levels 36 months after an acute coronary syndrome (ACS).
Methods
All patients admitted with ACS at the local county hospital between 1st January 2010 and 31st December 2014 were screened for inclusion based on their ability to participate in a telephone-based follow-up. Participants were randomized into two parallel groups, an intervention group and a control group receiving usual care. BP and LDL-C were measured at one month, 12, 24 and 36 months. The intervention group received counseling and medical titration to attain treatment targets of BP (<140/<90 mmHG) and LDL-C (<2.5/<1.8 mmol/L). The primary outcome was LDL-C at 36 months.
Results
Out of 962 randomized patients, 797 were available for analysis after 36 months. In the intervention group, mean systolic blood pressure (SBP) was 4.1 mmHg lower (95% CI 1.7 - 6.4, p=0.001), diastolic blood pressure (DBP) was 2.8 mmHg lower (95% CI 1.4- 4.4, p<0.001) and mean LDL-C was 0.26 mmol/L lower (95% CI 0.12 - 0.4, p<0.001) when compared to the control group. The proportion of patients reaching treatment target goals was also significantly higher in the intervention group.
Conclusions
After 36 months of follow-up the nurse-led, telephone-based intervention led to significantly lower systolic blood pressure, diastolic blood pressure and LDL-C levels when compared to the control group. The intervention group also had a larger proportion of patients reaching target values.

Abstract
Background Glioma O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status informs clinical decision making. Worldwide different methods and cutoff levels are used, which can lead to discordant methylation results. Methods We conducted an international survey to clarify which methods are regularly used and why. We also explored opinions regarding international consensus on methods and cutoff. Results The survey had 152 respondents from 25 countries. MGMT methylation status is determined for all glioblastomas in 37% of laboratories. The most common methods are methylation-specific polymerase chain reaction (msPCR) (37%) and pyrosequencing (34%). A method is selected for simplicity (56%), cost-effectiveness (50%), and reproducibility of results (52%). For sequencing, the number of CpG sites analyzed varies from 1–3 up to more than 16. For 50% of laboratories, the company producing the kit determines which CpG sites are examined, whereas 33% select the sites themselves. Selection of cutoff is equally distributed among a cutoff defined in the literature, by the local laboratory, or by the outside laboratory performing the analysis. This cutoff varies, reported from 1% to 30%, and in 1 laboratory tumor is determined as methylated in case of 1 methylated CpG site of 17 analyzed. Some report tumors as unmethylated or weakly vs highly methylated. An international consensus on MGMT methylation method and cutoff is warranted by 66% and 76% of respondents, respectively. The method preferred would be msPCR (45%) or pyrosequencing (42%), whereas 18% suggest next-generation sequencing. Conclusion Although analysis of MGMT methylation status is routine, there is controversy regarding laboratory methods and cutoff level. Most respondents favor development of international consensus guidelines.

Abstract
Abstract
BACKGROUND
A seizure as the only symptom before diagnosing glioblastoma improves survival rate. Apart from seizures, the main presenting symptom of glioma in adults is cognitive dysfunction. The effect of generalized symptoms or loss of function on lead times and survival of glioblastoma has not been studied. Generalized symptoms include cognitive dysfunction, headache, dizziness and fatigue. Loss of function comprise paresis, sensory deficit and speech aberrations. The objective of this study was to evaluate the influence of different presenting symptoms regarding health care level, lead times and survival.
MATERIAL AND METHOD
Medical case notes regarding 189 consecutive patients with histopathologically verified glioblastoma, were reviewed for information about the date and level of care of the first medical appointment, presenting symptom/s, and date of the diagnostic radiology. The extent of surgery was noted. Data on oncologic treatment was retrieved. Summary statistics were provided for patient demographics and treatment factors. The estimates of overall survival were calculated using the Kaplan-Meier method. Survival time was calculated from the date of radiological diagnosis.
RESULTS
The majority of patients (66%) presented with generalized symptoms, which significantly reduced survival compared to not having generalized symptoms (mean survival 10.5 months vs 19.9 months, p=0.001). The most common generalized symptom was cognitive dysfunction which further reduced survival (mean survival 9.0 months, p=0.0001). Among the different cognitive aberrations, personality change and memory impairment were associated with a significantly poorer survival, (mean survival 7.9 months, p=0.015 and 8.0 months p=0.010, respectively). Disorientation also significantly reduced survival (mean survival 8.2 months p=0.001). Presenting with loss of function (58%) did not influence survival (mean survival 12.3 months). 32% of patients with an epileptic seizure as initial symptom had significantly prolonged survival compared to those not having an epileptic seizure (mean 18.9 months vs 11.0 months p=0.002). When comparing focal and secondary generalized epileptic seizures, focal epileptic seizures were more favorable. The first medical appointment was evenly distributed between primary health care and the emergency units. 8.4% of patients had multiple contacts in primary health care without being admitted to radiology or specialized care. All but one of them presented with generalized symptoms.
CONCLUSION
Glioblastoma patients presenting with generalized symptoms such as cognitive dysfunction are difficult to identify and have significantly poorer survival than other glioblastoma patients. Patients presenting with an epileptic seizure have shorter leadtime and longer survival.

Abstract
Introduction A water-soluble Cremophor EL-free formulation of paclitaxel, in which retinoic acid derivates solubilize paclitaxel by forming micelles (paclitaxel micellar), was studied for the first time in man to establish the maximum tolerated dose (MTD) and to characterize the pharmacokinetics (PK). Methods This was an open-label, one-arm, dose-escalating study in patients with advanced solid malignant tumours, for which no standard therapy was available or had failed. Paclitaxel micellar was given as 1-h intravenous infusion every 21 days for 3 cycles, mainly without premedication. Plasma samples were collected during 24 h at the first cycle and paclitaxel concentrations were assayed by high-performance liquid chromatography. PK was evaluated using a two-compartment model. Results Thirty-four patients received paclitaxel micellar at doses ranging between 90 and 275 mg/m2. MTD was established as 250 mg/m2. Fatigue and neuropathy were the most frequent dose-limiting toxicities. No hypersensitivity reactions were observed. PK of paclitaxel was evaluated in 25 data sets. Paclitaxel micellar had a rapid initial distribution phase, mean half-life 0.55 h, estimated to be completed 3 h after dosing and a mean terminal half-life of 8.8 h. Mean clearance was 13.4 L/h/m2 with fivefold interindividual variability. The residual areas after 10 h and 24 h were 15.7 ± 8.6% and 5.7 ± 3.9% of the area under the plasma concentration–time curve to infinite time (AUCinf), respectively. Conclusion No new side effects unknown for paclitaxel were observed. Maximum plasma concentration (Cmax) and AUCinf showed a tendency to increase linearly with dose within the 150–275 mg/m2 dose range. The possibility to administer paclitaxel micellar without steroid premedication makes it an attractive candidate for further studies in combination with immunotherapy.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND In the last decade, increasing evidence has evolved for early and maximal safe resection of diffuse low-grade gliomas (LGGs) regarding survival. However, changes in clinical practice are known to occur slowly and we do not know if the scientific evidence has yet resulted in changes in neurosurgical patterns of care. METHODS The Swedish Brain Tumor Registry was used to identify all patients with a first-time histopathological diagnosis of LGG between 2005 and 2015. For analysis of surgical treatment patterns, we subdivided assessed time periods into 2005-2008, 2009-2012, and 2013-2015. Population-based data on patient and disease characteristics, surgical management, and outcomes were extracted. RESULTS A total of 548 patients with diffuse World Health Organization grade II gliomas were identified: 142 diagnosed during 2005-2008, 244 during 2009-2012, and 162 during 2013-2015. Resection as opposed to biopsy was performed in 64.3% during 2005-2008, 74.2% during 2009-2012, and 74.1% during 2013-2015 (P = .08). There was no difference among the 3 periods regarding overall survival (P = .11). However, post hoc analysis of data from the 4 (out of 6) centers that covered all 3 time periods demonstrated a resection rate of 64.3% during 2005-2008, 77.4% during 2009-2012, and 75.4% during 2013-2015 (P = .02) and longer survival of patients diagnosed 2009 and onward (P = .04). CONCLUSION In this nationwide, population-based study we observed a shift over time in favor of LGG resection. Further, a positive correlation between the more active surgical strategy and longer survival is shown, although no causality can be claimed because of possible confounding factors.

Abstract
BACKGROUND/AIM The main objective of this study was to evaluate if there was an increased incidence of brain tumours between years 1980-2012, a time period when mobile phone usage has increased substantially. MATERIALS AND METHODS From the Swedish Cancer Registry, cases of meningiomas, low-grade gliomas (LGG) and high-grade gliomas (HGG) were identified in patients between 1980-2012. Direct age-standardised incidence rates were used to calculate incidence trends over time. RESULTS A total of 13,441 cases of meningiomas, 12,259 cases of high-grade gliomas and 4,555 cases of LGG were reported to the register during the study period. The results suggest that there may be a negative development in the trend for LGG of -0,016 cases per 100,000 and year, corresponding to a mean reduction of approximately 1% per year. CONCLUSION The present study was not able to demonstrate an increased incidence of glioma during the past 30 years in Sweden.

Abstract
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.

Abstract
Background: Vestibular Schwannoma (VS) is a benign neoplasm arising from the 8th cranial nerve, with surgery one of the treatment modalities. In a nation-wide registry study, we describe the baseline, treatment characteristics, and short-term outcome in patients surgically treated for VS. Methods: We performed a nationwide study with data from the Swedish Brain Tumor Registry (SBTR) for all adults diagnosed with VS 2009–2015. Patient symptoms, tumor characteristics, and postoperative complications were analyzed. Results: In total 348 patients underwent surgery for VS. Mean age was 50.6 ± 14.5 years and 165 patients (47.4%) were female. The most common symptom was focal neurological deficit (92.0%), with only 25 (7.2%) being asymptomatic prior to surgery, and 217 (63.6%) had no restriction in activity. Following surgery, 100 (28.7%) patients developed new deficit(s). In terms of postoperative complications; 11 (3.2%) had a hematoma, 35 (10.1%) an infection, 10 (2.9%) a venous thromboembolism, and 23 (6.6%) had a reoperation due to complication. There were no deaths within 30-days after surgery. When grouped according to tumor size (< 4 vs. ≥4 cm), those with ≥4 cm tumors were more often males (p = 0.02), had more often ICP related symptoms (p = 0.03) and shorter time from imaging to surgery (p < 0.01). Analysis of the younger (< 65 years) vs. elderly (≥65 years) revealed no difference in outcome except increased 1-year mortality (p = 0.002) in elderly. Conclusion: In this nation-wide registry-study, we benchmark the 30-day complication rate after VS surgery as collected by the SBTR. Further, we present the current neurosurgical outcome data from both VS smaller than 40 mm compared to larger tumors, as well as younger vs. elderly VS patients. Since surgical decision making is a careful consideration of short term risk vs. long term benefit, this information can be useful in clinical decision making.

Abstract
Background In this exploratory analysis of AVAglio, a randomized phase III clinical study that investigated the addition of bevacizumab (Bev) to radiotherapy/temozolomide in newly diagnosed glioblastoma, we aim to radiologically characterize glioblastoma on therapy until progression and investigate whether the type of radiologic progression differs between treatment arms and is related to survival and molecular data. Methods Five progression types (PTs) were categorized using an adapted algorithm according to MRI contrast enhancement behavior in T1- and T2-weighted images in 621 patients (Bev, n = 299; placebo, n = 322). Frequencies of PTs (designated as classic T1, cT1 relapse, T2 diffuse, T2 circumscribed, and primary nonresponder), time to progression (PFS), and overall survival (OS) were assessed within each treatment arm and compared with molecular subtypes and O6-methylguanine DNA methyltransferase (MGMT) promoter methylation status. Results PT frequencies differed between the Bev and placebo arms, except for "T2 diffuse" (12.4% and 7.1%, respectively). PTs showed differences in PFS and OS; with "T2 diffuse" being associated with longest survival. Complete disappearance of contrast enhancement during treatment ("cT1 relapse") showed longer survival than only partial contrast enhancement decrease ("classic T1"). "T2 diffuse" was more commonly MGMT hypermethylated. Only weak correlations to molecular subtypes from primary tissue were detected. Conclusions Progression of glioblastoma under therapy can be characterized radiologically. These radiologic phenotypes are influenced by treatment and develop differently over time with differential outcomes. Complete resolution of contrast enhancement during treatment is a favorable factor for outcome.

Abstract
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.

Abstract
BACKGROUND Low-grade gliomas (LGG) are slow-growing primary brain tumors that typically affect young adults. Advanced age is widely recognized as a poor prognostic factor in LGG. The impact of age on postoperative outcome in this patient group has not been systemically studied. METHODS We performed a nationwide register-based study with data from the Swedish Brain Tumor Registry (SBTR) for all adults diagnosed with a supratentorial LGG (WHO grade II astrocytoma, oligoastrocytoma, or oligodendroglioma) during 2005-2015. Patient- and tumor-related characteristics, postoperative complications, and survival were compared between three different age groups (18-39 years, 40-59 years, and ≥60 years). RESULTS We identified 548 patients; 204 patients (37.2%) aged 18-39 years, 227 patients (41.4%) aged 40-59 years, and 117 patients (21.4%) ≥60 years of age. Unfavorable preoperative prognostic factors (eg, functional status and neurological deficit) were more common with increased age (P < .001). In addition, overall survival was significantly impaired in those 60 years and above (P < .001). We observed a clear dose-response for age with separation of survival curves at 50 years. Biopsy was more common in patients ≥60 years (P < .001). Subgroup analysis of patients with resection revealed a higher amount of postoperative neurological deficits in older patients (P = .029). CONCLUSION In general, older patients with LGG have several unfavorable prognostic factors compared with younger patients but seem to tolerate surgery in a comparable fashion. However, more neurological deficits were observed following resections in elderly. Our data further support a cutoff at 50 years rather than 40 years for selection of high-risk patients.

Abstract
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.

Abstract
OBJECTIVES The human leucine-rich repeats and immunoglobulin-like domains (LRIG) protein family comprises the integral membrane proteins LRIG1, LRIG2 and LRIG3. LRIG1 is frequently down-regulated in human cancer, and high levels of LRIG1 in tumor tissue are associated with favorable clinical outcomes in several tumor types including non-small cell lung cancer (NSCLC). Mechanistically, LRIG1 negatively regulates receptor tyrosine kinases and functions as a tumor suppressor. However, the details of the molecular mechanisms involved are poorly understood, and even less is known about the functions of LRIG2 and LRIG3. The aim of this study was to further elucidate the functions and molecular interactions of the LRIG proteins. MATERIALS AND METHODS A yeast two-hybrid screen was performed using a cytosolic LRIG3 peptide as bait. In transfected human cells, co-immunoprecipitation and co-localization experiments were performed. Proximity ligation assay was performed to investigate interactions between endogenously expressed proteins. Expression levels of LMO7 and LIMCH1 in normal and malignant lung tissue were investigated using qRT-PCR and through in silico analyses of public data sets. Finally, a clinical cohort comprising 355 surgically treated NSCLC cases was immunostained for LMO7. RESULTS In the yeast two-hybrid screen, the two paralogous proteins LMO7 and LIMCH1 were identified as interaction partners to LRIG3. LMO7 and LIMCH1 co-localized and co-immunoprecipitated with both LRIG1 and LRIG3. Endogenously expressed LMO7 was in close proximity of both LRIG1 and LRIG3. LMO7 and LIMCH1 were highly expressed in normal lung tissue and down-regulated in malignant lung tissue. LMO7 immunoreactivity was shown to be a negative prognostic factor in LRIG1 positive tumors, predicting poor patient survival. CONCLUSION These findings suggest that LMO7 and LIMCH1 physically interact with LRIG proteins and that expression of LMO7 is of clinical importance in NSCLC.

Abstract
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.

Abstract
New data show a continuously increased five-year survival for almost all analyzed cancer diagnoses since 1990. It has to be emphasized that the figures are uncertain due to the limited number of patients. The variation is huge and the greatest improvements are seen not least among the three major tumor diseases (breast, colorectal and prostate cancer), where the society, industry and research bodies made the biggest investments over the years. The causes of improved survival can be sought in several areas, such as earlier detection and better treatments. In addition to survival estimates, it is also always of importance to consider aspects around patient related outcome, such as quality of life.

Abstract
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.

Abstract
Papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC) are characterized by genomic rearrangements and point mutations in the proto-oncogene RET. Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) is a suppressor of various receptor tyrosine kinases, including RET. LRIG1 expression levels are associated with patient survival in many cancer types. In the present study, we investigated whether the oncogenic RET mutants RET2A (C634R) and RET2B (M918T) were regulated by LRIG1, and the possible effects of LRIG1 expression in thyroid cancer were investigated in three different clinical cohorts and in a RET2B-driven mouse model of MTC. LRIG1 was shown to physically interact with both RET2A and RET2B and to restrict their ligand-independent activation. LRIG1 mRNA levels were downregulated in PTC and MTC compared to normal thyroid gland tissue. There was no apparent association between LRIG1 RNA or protein expression levels and patient survival in the studied cohorts. The transgenic RET2B mice developed pre-cancerous medullary thyroid lesions at a high frequency (36%); however, no overt cancers were observed. There was no significant difference in the incidence of pre-cancerous lesions between Lrig1 wild-type and Lrig1-deficient RET2B mice. In conclusion, the findings that LRIG1 is a negative regulator of RET2A and RET2B and is also downregulated in PTC and MTC may suggest that LRIG1 functions as a thyroid tumor suppressor.

Abstract
Recently, a genome-wide association study showed that a single nucleotide polymorphism (SNP) —rs11706832—in intron 2 of the human LRIG1 (Leucine-rich repeats and immunoglobulin-like domains 1) gene is associated with susceptibility to glioma. However, the mechanism by which rs11706832 affects glioma risk remains unknown; additionally, it is unknown whether the expression levels of LRIG1 are a relevant determinant of gliomagenesis. Here, we investigated the role of Lrig1 in platelet-derived growth factor (PDGF)-induced experimental glioma in mice by introducing mono-allelic and bi-allelic deletions of Lrig1 followed by inducing gliomagenesis via intracranial retroviral transduction of PDGFB in neural progenitor cells. Lrig1 was expressed in PDGFB-induced gliomas in wild-type mice as assessed using in situ hybridization. Intriguingly, Lrig1-heterozygous mice developed higher grade gliomas than did wild-type mice (grade IV vs. grade II/III, p = 0.002). Reciprocally, the ectopic expression of LRIG1 in the TB107 high-grade human glioma (glioblastoma, grade IV) cell line decreased the invasion of orthotopic tumors in immunocompromised mice in vivo and reduced cell migration in vitro. Concomitantly, the activity of the receptor tyrosine kinase MET was downregulated, which partially explained the reduction in cell migration. In summary, Lrig1 is a haploinsufficient suppressor of PDGFB-driven glioma, possibly in part via negative regulation of MET-driven cell migration and invasion. Thus, for the first time, changes in physiological Lrig1 expression have been linked to gliomagenesis, whereby the SNP rs11706832 may affect glioma risk by regulating LRIG1 expression.
