- PURPOSE: This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects.METHODS: Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs.RESULTS: CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (β = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = -0.16,95%CI = -0.25;-0.07) and anxiety (β = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05).CONCLUSIONS: CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

- Background: Neoadjuvant treatment with Trastuzumab-emtansine was associated with similar rates of pathological complete remission (pCR) as standard therapy withd ocetaxel, trastuzumab and pertuzumab in the PREDIX HER2 trial. Here, results of event-free survival (EFS), and pCR rates in key clinical-pathological subgroups and biomarkers including the abundance of stromal tumor infiltrating lymphocytes (TILs) are presented.Methods: PREDIX HER2 is a randomized, multicenter, open-label, phase 2 study involving 9 Swedish sites. Patients with HER2 positive breast cancer, verified by ISH, T>20 mm and/or verified lymph node metastases were randomized to six three-weekly courses of either docetaxel, trastuzumab SC and pertuzumab (group A), or trastuzumab emtansine (T-DM1, group B). Switch of treatment to the opposite arm was allowed in case of lack of response or severe toxicity. Radiological evaluation included 18F-FDG PET/CT. Patients in both groups received adjuvant chemotherapy with epirubicin and cyclophosphamide. TILs were evaluated using standard methodology, median 10%.Results: In total 197 pts. were evaluable, 99 in group A, and 98 in group B. pCR (ypT0/is ypN0) was achieved in 90 pts, 45.7%, with no significant difference between the two treatment groups. pCR rates were lower in the group of patients with hormone receptor (HR)epositive compared with HR-negative tumors but similar in both treatment groups. pCR rates did not differ between the two treatments in subgroups defined by age, menopausal status, tumor grade, T size, node status, HR-status, HER2 status and Ki67. Progressive disease was observed in 3 pts. (3%) during treatment with T-DM1, none in group A. After a median follow-up of 2.4 years 13 EFS events occurred, with no significant differences between the treatment groups. The presence of 10% TILs predicted pCR significantly (p¼0.009), similar in both treatment groups. We also found that a decrease of SUVmax by more than 80% was highly predictive of pCR. HRQoL was significantly better in pts. receiving T-DM1.Conclusions: Our data suggest that neoadjuvant T-DM1 may be as effective as standard neoadjuvant treatment in all clinical subgroups evaluated. Both TILs and PET/CT showed potential to predict pCR.Clinical trial identification: NCT02568839.

- Objective: This individual patient data (IPD) meta-analysis aimed to evaluate the effects of psychosocial interventions (PSI) on quality of life (QoL), emotional function (EF), and social function (SF) in patients with cancer, and to study moderator effects of demographic, clinical, personal, and intervention-related characteristics. Methods: Relevant studies were identified via literature searches in 4 databases. We pooled IPD from 22 (n = 4217) of 61 eligible randomized controlled trials. Linear mixed-effect model analyses were used to study intervention effects on the post-intervention values of QoL, EF, and SF (z-scores), adjusting for baseline values, age, and cancer type. We studied moderator effects by testing interactions with the intervention for demographic, clinical, personal, and intervention-related characteristics, and conducted subsequent stratified analyses for significant moderator variables.Results: PSI significantly improved QoL (=0.14,95%CI=0.06;0.21), EF ( beta = 0.13,95%CI = 0.05;0.20), and SF (beta = 0.10,95%CI = 0.03;0.18). Significant differences in effects of different types of PSI were found, with largest effects of psychotherapy. The effects of coping skills training were moderated by age, treatment type, and targeted interventions. Effects of psychotherapy on EF may be moderated by cancer type, but these analyses were based on 2 randomized controlled trials with small sample sizes of some cancer types. Conclusions: PSI significantly improved QoL, EF, and SF, with small overall effects. However, the effects differed by several demographic, clinical, personal, and intervention-related characteristics. Our study highlights the beneficial effects of coping skills training in patients treated with chemotherapy, the importance of targeted interventions, and the need of developing interventions tailored to the specific needs of elderly patients.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The primary aim was to compare long-term health-related quality of life (HRQoL) in patients undergoing sentinel lymph node biopsy (SLNB) alone versus axillary lymph node dissection (ALND), with or without axillary metastases. Secondary aims were to a) investigate agreement between objectively measured and self-reported lymphoedema and b) compare, with respect to HRQoL, women with objective arm lymphoedema without subjective ratings and those with no objective but subjective ratings of arm lymphoedema.METHODS: The three study groups were defined by axillary surgery: 1) SLNB alone (N = 140), 2) ALND in patients without axillary metastases (N = 125) and 3) ALND in patients with axillary metastases (N = 155). Preoperatively, one and three years postoperatively arm volume was measured and questionnaires regarding self-perceived symptoms of arm lymphoedema and HRQoL were completed (The Swedish Short Form-36 Health Survey, SF-36).RESULTS: Out of the original 516 who had axillary surgery, 420 (81%) completed the study. There were no statistically significant differences in HRQoL between the three study groups. No statistically significant agreement was found between self-perceived and objectively measured arm lymphoedema. Women without self-perceived arm lymphoedema, regardless of objective arm lymphoedema or not, scored higher on all eight SF-36 domains than those who reported self-perceived arm lymphoedema.CONCLUSION: Women reporting self-perceived arm lymphoedema, regardless of objective lymphoedema or not, have a decreased long-term health-related quality of life. This indicates that more attention should be given to the subjective reports of symptom in order to better help these women.

- In the Robot Assisted Surgery for High Risk Endometrial Cancer (RASHEC) trial, patients with high-risk endometrial cancer were randomly assigned to robot-assisted laparoscopic surgery (RALS) or laparotomy for pelvic and infrarenal para-aortic lymph node dissection. We here report on self-reported lower limb lymphedema (LLL), lymphocyst formation, ascites, and long-term serious adverse events 12 months after surgery.Patients and methodsPatients were enrolled between 2013 and 2016, and 96 patients were included in the per protocol analysis, evenly distributed between RALS and laparotomy. Self-reported LLL was recorded using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire for endometrial cancer—EN24, assessed before and 12 months after surgery. Computed tomography was assessed at baseline, 3, and 12 months. Medical charts were reviewed for serious adverse events and hospital admissions 31 to 365 days after surgery.ResultsAt 12 months after laparotomy and RALS, 61% and 50% patients, respectively, reported LLL (p = 0.31). In univariate analysis, the mean score of LLL at 12 months was significantly higher for laparotomy than for RALS (p < 0.05) and for those without abdominal drainage (p = 0.02), but was not independently associated with LLL in the multivariate analysis. Imaging showed no significant difference in lymphocyst formation or ascites between surgical modalities. No difference was found in serious adverse events and admissions to hospital for any reason. There was no agreement between lymphocyst formation or ascites and self-reported LLL.ConclusionFollow-up 1 year after comprehensive surgical staging for high-risk endometrial cancer showed no differences in self-reported LLL, findings on imaging, or SAE between laparotomy and robot-assisted surgery.

- BACKGROUND. Conventional interferon-a (IFN) is an effective treatment for patients with myeloproliferative disorders. However, many patients discontinue therapy because of side effects. METHODS. In this 24-month, Phase II feasibility study of pegylated interferon a-2b (PEG-IFN) treatment, a starting dose of 0.5 µg/kg per week was received by 21 patients with polycythemia vera (PV) and 21 patients with essential thrombocythemia (ET). The treatment objective, a complete platelet response (CR), was a platelet count <400 × 109/L in symptomatic patients and <600 in asymptomatic patients. Neutrophil polycythemia rubra vera-1 (PRV-1) messenger RNA expression was analyzed prior to and during therapy. Quality of life (QoL) was investi-gated by using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire. RESULTS. At 6 months, 29 of 42 patients (69%) had achieved a CR after a median of 83 days. The CR rate was not related to diagnosis, gender, or previous therapy. Nineteen patients completed the planned 2-year treatment in CR. No thromboembolic or bleeding complications were observed. Phlebotomy requirements were reduced in the majority of patients with PV. Five of 14 patients (36%) who initially were positive for PRV-1 achieved normalized PRV-1 expression under PEG-IFN treatment. Side effects were the cause of therapy failure in 16 of 23 patients. However, only 8 of 19 patients reported any side effects at 2 years. The QLQ-C30 revealed clinically significant impairments in several aspects of QoL at 6 months, however, at 2 years, QoL measurements were not different from baseline. CONCLUSIONS. PEG-IFN effectively reduced platelet counts in 29 of 42 patients, but only 19 patients maintained a CR at 2 years. The reversal of PRV-1 positivity noted in a subset of patients suggested that PEG-IFN may have an effect on the malignant clone. PEG-IFN is a valuable therapeutic alternative for patients who tolerate its initial side effects. © 2006 American Cancer Society.

- Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

- Management of acute chest pain focuses on diagnosis or safe rule-out of an acute coronary syndrome (ACS). We aim to determine the additional value of self-reported computerised history taking (CHT).Methods and analysisProspective cohort study design with self-reported, medical histories collected by a CHT programme (Clinical Expert Operating System, CLEOS) using a tablet. Women and men presenting with acute chest pain to the emergency department at Danderyd University Hospital (Stockholm, Sweden) are eligible. CHT will be compared with standard history taking for completeness of data required to calculate ACS risk scores such as History, ECG, Age, Risk factors and Troponin (HEART), Global Registry of Acute Coronary Events (GRACE), and Thrombolysis in Myocardial Infarction (TIMI). Clinical outcomes will be extracted from hospital electronic health records and national registries. The CLEOS-Chest Pain Danderyd Study project includes (1) a feasibility study of CHT, (2) a validation study of CHT as compared with standard history taking, (3) a paired diagnostic accuracy study using data from CHT and established risk scores, (4) a clinical utility study to evaluate the impact of CHT on the management of chest pain and the use of resources, and (5) data mining, aiming to generate an improved risk score for ACS. Primary outcomes will be analysed after 1000 patients, but to allow for subgroup analysis, the study intends to recruit 2000 or more patients. This ongoing project may lead to new and more effective ways for collecting thorough, accurate medical histories with important implications for clinical practice.Ethics and disseminationThis study has been reviewed and approved by the Stockholm Regional Ethical Committee (now Swedish Ethical Review Authority). Results will be published, regardless of the outcome, in peer-reviewed international scientific journals.Trial registration numberThis study is registered athttps://www.clinicaltrials.gov(unique identifier:NCT03439449).

- PURPOSE: To compare health-related quality of life (HRQoL) and side-effects in patients with high-risk melanoma participating in a randomised phase III trial of adjuvant interferon alfa-2b (IFN). PATIENTS AND METHODS: A total of 855 patients with histologically verified resected cutaneous melanoma in AJCC stage IIb (T4 N0 M0) or stage III (Tx N1-3 M0) were randomised to: Arm A: observation only (n=284); Arm B: 1-year treatment: induction: IFN alfa-2b, 10 MU (flat dose), SC, 5days/week, 4weeks, maintenance: IFN alfa-2b, 10 MU (flat dose), SC, 3days/week for 12months (n=285); or Arm C: 2years of same treatment as Arm B. HRQoL was assessed using The European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) before randomisation and at 8 pre-defined time-points during 2years. IFN-related side-effects were assessed by a study-specific questionnaire. RESULTS: >80% of eligible patients returned questionnaires at the different assessment points. Statistically significant interactions between randomisation arm and time after randomisation were found for almost all EORTC QLQ-30 variables. While patients in Arm A improved or remained at baseline levels; patients in Arms B and C reported decreased functioning and quality of life, and an increase in side-effects during their treatment. Patients in Arm B improved after the 12th month assessment, when IFN treatment was scheduled to end, to the 16th month assessment (p<0.001). The same pattern of improvement was found for 5 of 7 interferon-related side-effects. CONCLUSION: A significant negative impact on HRQoL of IFN treatment was demonstrated, however the impact were reversible when treatment was stopped.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate the role of 70Gy salvage radiotherapy (SRT) combined with short-term neoadjuvant hormonal therapy (NHT) in the treatment of recurrent disease after radical prostatectomy (RP), and to consider quality of life (QoL), survival outcomes and impact of co-morbidities on treatment-related rectal-genitourinary toxicity. Electronic records of 184 SRT patients treated consecutively between October 2001 and February 2007 were analyzed. Median age was 64 years (median follow-up 48months). NHT was given to 165 patients (median 3 months). Pre-RP and pre-SRT PSA, PSA doubling time, Gleason score (GS), seminal vesicle invasion (SVI) and detectable post-SRT PSA were recorded. Any detectable PSA or PSA >0.1 ng/ml + nadir was considered biochemical failure (BcF). The Charlson co-morbidity index was used to correlate co-morbidities and rectal-genitourinary toxicity. Scores from the health-related QoL EORTC QLQ-C30 and PR-25 questionnaires were also evaluated. In 116 (63%) patients, a long-lasting curative effect was indicated by undetectable PSA levels. In univariate analysis, using BcF as an outcome variable, p<0.001 was found for GS, pre-SRT PSA, SVI and detectable post-SRT PSA. Multivariate analysis showed p=0.01 for SVI, p=0.09 for GS, and detectable post-SRT PSA (p=0.01); with metastases as an outcome variable, only SVI was significant (p=0.007). Cancer-specific and overall survival were 99 and 95%, respectively. Although microscopy showed SVI or GS 8-10 in the prostatectomy specimens 17/40(43%) and 13/29 (45%), respectively, of patients still showed undetectable PSA at long-term follow-up (median 55 months) after SRT. Likewise, 11/31 (36%) patients with pre-SRT PSA >1.0 ng/ml and 80/134 (60%) patients with PSA doubling time (PSADT) <10 still showed undetectable PSA after 50 months. Slightly elevated acute and late rectal-genitourinary grade 3-4 toxicity was observed. No association with co-morbidity/toxicity was found. EORTC QLQ-C30 scores were similar to or slightly better than reference values. SRT with 70 Gy combined with 3-month NHT results in long-term undetectable PSA in >50% of patients with recurrence after RP with acceptable rectal-genitourinary toxicity and without negatively affecting long-term QoL. Non-metastatic patients should not be disqualified from receiving SRT although presenting with poor prognostic factors at surgery.

- 36 Background: Prostate-specific antigen (PSA) is used to screen for prostate cancer but suffers from a high false-positive rate that translates into unnecessary prostate biopsies and over-diagnosis of low-risk prostate cancers. We aimed to develop a model for prostate cancer screening with better test characteristics than PSA. Methods: STHLM3 is a prospective, population-based, paired screen-positive diagnostic study. It investigates whether the predefined STHLM3 model, a combination of 6 plasma protein biomarkers (PSA, free-PSA, intact-PSA, HK2, MIC-1, and MSMB), genetic polymorphisms (232 SNPs), and clinical variables (age, family history, previous biopsies, DRE, and prostate volume) can substantially reduce the proportion of men biopsied while maintaining the same sensitivity to diagnose Gleason score ≥ 7 prostate cancer as PSA ≥3 ng/ml. In addition, a health economic evaluation was performed comparing the STHLM3 model with current clinical practice in Stockholm. Results: 58,818 men without prostate cancer aged 50-69, participated in the STHLM3 study, with 6,700 undergoing subsequent prostate biopsy. The STHLM3 model performed significantly better (p<0.001) than PSA for detecting GS ≥7 cancers, increasing the Area Under the Curve from 0.56 to 0.74. All variables used in the STHLM3 Model were significantly associated with Gleason score ≥7 prostate cancers (p<0.05) in a multiple logistic regression model. Using the same sensitivity as PSA ≥3 ng/ml to diagnose Gleason score ≥7 prostate cancer, the STHLM3 model reduced the number of biopsies by 32% (95% CI 24%-39%) and avoided 44% (95% CI; 35%-54%) of the negative biopsies. The number of Gleason score 6 cancers was reduced by 17% (95% CI; 7%-26%). Positive ICER for the STHLM3 model was seen in all models of the health economic analysis. Conclusions: The STHLM3 model reduces unnecessary biopsies without compromising the ability to diagnose Gleason score ≥7 prostate cancer in a cost-efficient way.

- Anthracyclines and taxanes are active cytotoxic drugs in the treatment of early metastatic breast cancer. It is yet unclear whether addition of capecitabine to the combination of these drugs improves the treatment outcome. Patients with advanced breast cancer were randomized to first-line chemotherapy with a combination of epirubicin (Farmorubicin(A (R))) and paclitaxel (Taxol(A (R))) alone (ET) or in combination with capecitabine (Xeloda(A (R)), TEX). Starting doses for ET were epirubicin 75 mg/m(2) plus paclitaxel 175 mg/m(2), and for TEX epirubicin 75 mg/m(2), paclitaxel 155 mg/m(2), and capecitabine 825 mg/m(2) BID for 14 days. Subsequently, doses were tailored related to side effects. Primary endpoint was progression-free survival (PFS); secondary endpoints were overall survival (OS), time to treatment failure (TTF), objective response (OR), safety and quality of life (QoL). 287 patients were randomized, 143 to ET and 144 to TEX. Median PFS was 10.8 months for patients treated with ET, and 12.4 months for those treated with TEX (HR 0.84, 95% CI 0.65-1.07, P = 0.16); median OS was 26.0 months for women in the ET versus 29.7 months in the TEX arm (HR 0.84, 95% CI 0.63-1.11, P = 0.22). OR was achieved in 44.8% (ET) and 54.2% (TEX), respectively (chi(2) 3.66, P = 0.16). TTF was significantly longer for patients treated with TEX, 6.0 months, versus 5.2 months following ET (HR 0.73, 95% CI 0.58-0.93, P = 0.009). Severe hematological side effects related to epirubicin and paclitaxel were evenly distributed between the treatment arms, mucositis, diarrhea, and Hand-Foot syndrome were significantly more frequent in the TEX arm. Toxicity-adjusted treatment with ET and TEX showed similar efficacy in terms of PFS, OS, and OR. In this trial with limited power, the addition of capecitabine to epirubicin and paclitaxel as first-line treatment did not translate into clinically relevant improvement of the outcome.
