RESUMO

BACKGROUND: EMIT-1 is a national, observational, single-arm trial designed to assess the value of the Prosigna, Prediction Analysis of Microarray using the 50 gene classifier (PAM50)/Risk of Recurrence (ROR), test as a routine diagnostic tool, examining its impact on adjuvant treatment decisions, clinical outcomes, side-effects and cost-effectiveness. Here we present the impact on treatment decisions. PATIENTS AND METHODS: Patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative pT1-pT2 lymph node-negative early breast cancer (EBC) were included. The Prosigna test and standard histopathology assessments were carried out. Clinicians' treatment decisions were recorded before (pre-Prosigna) and after (post-Prosigna) the Prosigna test results were disclosed. RESULTS: Of 2217 patients included, 2178 had conclusive Prosigna results. The pre-Prosigna treatment decisions were: no systemic treatment (NT) in 27% of patients, endocrine treatment alone (ET) in 38% and chemotherapy (CT) followed by ET (CT + ET) in 35%. Post-Prosigna treatment decisions were 25% NT, 51% ET and 24% CT + ET, respectively. Adjuvant treatment changed in 28% of patients, including 21% change in CT use. Among patients assigned to CT + ET pre-Prosigna, 45% were de-escalated to ET post-Prosigna. Of patients assigned to ET, 12% were escalated to CT + ET and 8% were de-escalated to NT; of those assigned to NT, 18% were escalated to ET/CT + ET. CT was more frequently recommended for patients aged ≤50 years. In the subgroup with pT1c-pT2 G2 and intermediate Ki67 (0.5-1.5× local laboratory median Ki67 score), the pre-Prosigna CT treatment decision varied widely across hospitals (3%-51%). Post-Prosigna, the variability of CT use was markedly reduced (8%-24%). The correlation between Ki67 and ROR score within this subgroup was poor (r = 0.25-0.39). The median ROR score increased by increasing histological grade, but the ROR score ranges were wide (for G1 0-79, G2 0-90, G3 16-94). CONCLUSION: The Prosigna test result changed adjuvant treatment decisions in all EBC clinical risk groups, markedly decreased the CT use for patients categorized as higher clinical risk pre-Prosigna and reduced treatment decision discrepancies between hospitals.

RESUMO

PURPOSE: Chronic fatigue (CF) affects 25-30% of lymphoma survivors, but interventions designed to reduce fatigue are lacking. The main aim of this study was to test the feasibility of a multidimensional intervention study in lymphoma survivors with CF. Secondary aims were to describe individual changes in fatigue, quality of life (QoL) and physical performance from pre (T0) to post (T1) intervention. METHODS: This feasibility study was as a one-armed intervention study performed in 2021. Hodgkin or aggressive non-Hodgkin lymphoma survivors received mailed study information and Chalder Fatigue Questionnaire and were asked to respond if they suffered from fatigue. The 12-week intervention included patient education, physical exercise, a cognitive behavioural therapy (CBT)-based group program and nutritional counselling. Feasibility data included patient recruitment, completion of assessments, adherence to the intervention and patient-reported experience measures. Participants responded to questionnaires and underwent physical tests at T0 and T1. RESULTS: Seven lymphoma survivors with CF were included. Of all assessments, 91% and 83% were completed at T0 and T1, respectively. Adherence to the interventional components varied from 69% to 91%. At T1, all participants rated exercise as useful, of whom five rated the CBT-based program and five rated individual nutritional counselling as useful. Five participants reported improved fatigue, QoL and physical performance. CONCLUSION: Lymphoma survivors with CF participating in a multidimensional intervention designed to reduce the level of fatigue showed high assessment completion rate and intervention adherence rate. Most of the participants evaluated the program as useful and improved their level of fatigue, QoL and physical performance after the intervention.

RESUMO

BACKGROUND: The aim of this study was to characterize the prevalence of self-reported adverse health outcomes (AHOs), track changes in AHOs, and examine their impact on health-related quality of life (HrQoL) in testicular cancer survivors (TCSs) who were diagnosed between 1980 and 1994. These assessments were conducted during two survey waves (SWs), with the first occurring ∼12 years after surgery-only or platinum-based chemotherapy (PBCT), and the second ∼28 years after initial treatment. The study primarily focused on 'typical AHOs', which included Peripheral Sensory Neuropathy (PSN), Raynaud's phenomenon, Tinnitus, and Hearing loss. PATIENTS AND METHODS: A total of 427 TCSs were included in the evaluation, distributed as follows: surgery-only group (n = 155), PBCT-standard group with ≤850 mg cisplatin (n = 222), and PBCT-high group with >850 mg cisplatin (n = 50). For comparison of HrQoL, men from the general population served as a control group (referred to as 'Norms'). The statistical significance level was set at P < 0.05, and clinical importance, in terms of testing HrQoL differences, was defined as Δ ≥2.5 points. RESULTS: A higher number of TCSs who underwent PBCT reported experiencing typical AHOs compared with those who had surgery only. The highest prevalence rates were observed among TCSs who had undergone PBCT-high. Further, the number of TCSs describing typical AHOs, except Raynaud's phenomenon, increased during the observation period of 16 years. At the last SW, a median of 4 AHOs (any type) were reported after PBCT-high compared with a median of 2 AHOs after Surgery-only or after PBCT-standard. With Surgery-only as reference, PBCT-high, but not PBCT-standard, was associated with decreasing physical HrQoL in the last SW (A2 Regression coefficient: -4.3; P = 0.008). When comparing all TCSs with Norms no clinically important difference in physical and mental HrQoL was observed at either SW. However, at the last SW, TCSs after PBCT-high therapy represented a subgroup of TCSs with clinically important impairment of HRQoL. Of the typical AHOs, only PSN reduced HrQoL. Chronic fatigue, pain, anxiety/depression, sexual dysfunction, unemployment, being single, and low education were additional covariates. CONCLUSIONS: After a median of 28 years since their treatment, HrQoL in TCSs was found to be comparable to that of Norms. This similarity held true even though AHOs, especially after PBCT-high, were becoming more prevalent among TCSs. The study revealed that individuals with a history of PBCT-high are at a high risk of experiencing a significantly increased prevalence of long-term AHOs, which subsequently leads to diminished HrQoL. It is crucial to recognize and provide specialized attention to these TCSs during lifelong follow-up care.

RESUMO

PURPOSE: Head and neck cancer (HNC) treatment may lead to late effects and impaired health-related quality of life of survivors. Knowledge on long-term late effects after radiotherapy (RT) and potential underlying biological mechanisms is lacking. We assessed the prevalence of xerostomia, dysphagia, and chronic fatigue (CF) in HNC survivors ≥ 5 years post-RT, and examined associations between pro-inflammatory cytokines and late effects. METHODS: In a cross-sectional study, 263 HNC survivors treated between 2007 and 2013 were enrolled. They completed validated questionnaires assessing xerostomia and dysphagia (the EORTC QLQ-H&N35), and CF (the Fatigue Questionnaire), and underwent blood sampling and clinical examination. Pro-inflammatory cytokines were analyzed in 262 survivors and 100 healthy age- and gender-matched controls. RESULTS: Median time since treatment was 8.5 years. The proportions of survivors reporting xerostomia, dysphagia, and CF were 58%, 31%, and 33%, respectively, with a preponderance of females. We found no significant associations between IL-6, IL-8, IP-10, TARC, TNF, or ENA-78 and the three late effects. The odds of having elevated levels of IL-6 and IP-10 were significantly higher in the survivors compared to the controls. CONCLUSIONS: More than one-third of long-term HNC survivors experienced xerostomia, dysphagia, and CF. Persistent inflammation, with elevated systemic cytokines, was not associated with these late effects, although HNC survivors had higher levels of some cytokines than the controls. IMPLICATIONS FOR CANCER SURVIVORS: This study provides new knowledge on late effects that can serve as grounds for informing patients with HNC about risk of late effects more than 5 years after RT.

RESUMO

INTRODUCTION: As the 5-year survival rate after breast cancer in Norway is 92%, the population of breast cancer survivors (BCSs) is increasing. Knowledge of work ability in this population is scarce. In a population-based cohort of BCSs, we explored work ability 8 years after diagnosis and the association between work ability and social support, and cancer-related variables including late effects and lifestyle factors. METHODS: In 2019, all Norwegian women < 59 years when diagnosed with stage I-III breast cancer in 2011 or 2012, were identified by the Cancer Registry of Norway and invited to participate in a survey on work life experiences. Work ability was assessed using the Work Ability Index (scale 0-10). Factors associated with excellent work ability (score ≥ 9) were identified using univariate and multivariate logistic regression analyses, and adjusted for socioeconomic-, health- and cancer-related variables. RESULTS: Of the 1951 eligible BCSs, 1007 (52.8%) responded. After excluding survivors with relapse (n = 1), missing information on work ability score (n = 49), or work status (n = 31), the final sample comprised 926 BCSs within working age at survey (< 67 years). Mean age at survey was 56 years and 8 years (SD 0.7) had passed since diagnosis. Work ability had been reduced from 8.9 (SD 2.3) at diagnosis to 6.3 (SD 3.1). One in three BCSs reported poor work ability (WAS ≤ 5), and seven out of ten reported that their physical work ability had been reduced due to cancer. Social support from colleagues during cancer therapy was associated with excellent work ability, which was not observed for social support provided by supervisors or the general practitioner. Cognitive impairment and fatigue were inversely associated with work ability. None of the cancer-related variables, including treatment, were associated with work ability 8 years after diagnosis. CONCLUSION: In this population-based sample, one in three BCSs reported poor work ability 8 years after diagnosis. Collegial social support during cancer therapy appears to be a protective factor for sustained work ability, whilst survivors struggling with fatigue and cognitive impairments may represent a particularly vulnerable group for reduced work ability.

RESUMO

PURPOSE: The study aims to describe work status at diagnosis and 8 years post-diagnosis in a nationwide sample of breast cancer survivors (BCSs), and investigate associated and self-reported factors of reduced work status. METHODS: Women aged 20-65 years when diagnosed with stage I-III breast cancer (BC) in 2011 or 2012 were invited to participate in a questionnaire study in 2019 (n = 2803), of whom 49% (n = 1361) responded. For this sub-study, we included 974 BCSs below the legal retirement age in Norway (< 67 years) at survey and with complete work status data. Reduced work status was defined as being in paid work at BC diagnosis and not working at time of survey. Logistic regression analyses were applied to identify factors associated with reduced work status. RESULTS: Of BCSs who were in paid work at diagnosis (n = 845), 63% maintained their work status to 8 years later. Reduced work status was associated with not living with children (OR .44, 95% CI .24-.82), age (OR 1.16, 95% CI 1.11-1.21), chemotherapy (OR 2.83, 95% CI 1.24-6.61), > 2 comorbid conditions (OR 2.27, 95% CI 1.16-4.32), cognitive function (OR .99, 95% CI .98-.99), fatigue (OR 1.02, 95% CI 1.01-1.03), and neuroticism (OR 1.57, 95% CI 1.00-2.46). BC and late effects were reported as reasons for reduced work status and disability. CONCLUSIONS: The majority of BCSs who were in paid work at diagnosis were working 8 years later. IMPLICATIONS FOR CANCER SURVIVORS: Our results suggest a need to focus on fatigue and reduced cognitive function among long-term BCSs, with the ultimate aim of improving work sustainability.

RESUMO

PURPOSE: The majority of childhood, adolescent, and young adult cancer survivors (CAYACS) are at risk of late effects but may not receive long-term follow-up care for these. Here, we investigated (1) self-reported late effects, (2) long-term follow-up care, and (3) factors associated with receiving follow-up care in a population-based sample of Norwegian long-term CAYACS. METHODS: Survivors were identified by the Cancer Registry of Norway. All > 5-year survivors diagnosed between 1985 and 2009 with childhood cancer (CCS, 0-18 years old, excluding CNS), breast cancer (BC, stages I-III), colorectal cancer (CRC), leukemias (LEUK), non-Hodgkin lymphoma (NHL), or malignant melanoma (MM) at age 19-39 years were mailed a questionnaire (NOR-CAYACS study). Descriptive statistics and logistic regression models were used to analyze occurrence of late effects, long-term follow-up care for these, and associated factors. RESULTS: Of 2104 responding survivors, 1889 were eligible for analyses. Of these, 68% were females, with a mean age of 43 years at survey, on average 17 years since diagnosis, and diagnosed with CCS (31%), BC (26%), CRC (8%), NHL (12%), LEUK (7%), and MM (16%). Overall, 61.5% reported the experience of at least one late effect, the most common being concentration/memory problems (28.1%) and fatigue (25.2%). Sixty-nine percent reported not having received long-term follow-up care focusing on late effects. Lower age at survey (p = 0.001), higher education (p = 0.012), and increasing number of late effects (p = < 0.001) were associated with increased likelihood of follow-up care in the multivariate model. CONCLUSIONS: The majority of survivors reported at least one late effect, but not receiving specific follow-up care for these. This indicates a need for structured models of long-term follow-up to ensure adequate access to care.

RESUMO

Background This study examined employment patterns and associated factors in lymphoma survivors treated with high-dose chemotherapy with autologous stem cell transplantation (HDT-ASCT) from diagnosis to a follow-up survey at a mean of 10 years after HDT-ASCT. Patients and methods All lymphoma survivors aged ≥18 years at HDT-ASCT in Norway from 1987 to 2008, and alive at the end of 2011 were eligible for this cross-sectional study performed in 2012/2013. Participants completed a mailed questionnaire. Job status was dichotomized as either employed (paid work) or not-employed (disability and retirement pension, on economic support, home-makers, or students). Results The response rate was 78%, and the sample (N = 312) contained 60% men. Mean age at HDT-ASCT was 44.3 and at survey 54.0 years. At diagnosis 85% of survivors were employed, 77% before and 77% after HDT-ASCT, and 58% at follow-up. Forty seven percent of the survivors were employed at all time points. The not-employed group at survey was significantly older and included significantly more females than the employed group. No significant between-group differences were observed for lymphoma-related variables. Fatigue, mental distress and type D personality were significantly higher among those not-employed, while quality of life was significantly lower compared to the employed group. Older age at survey, being female, work ability and presence of type D personality remained significantly related to being not-employed at survey in the multivariable analysis. Conclusions Our findings show that not-employed long-term survivors after HDT-ASCT for lymphoma have more comorbidity, cognitive problems and higher levels of anxiety/depression than employed survivors. These factors should be checked and eventually treated in order to improve work ability.

RESUMO

BACKGROUND: Chronic fatigue (CF) has been reported to be slightly more prevalent in testicular cancer survivors (TCSs) than in the general population. In this study, we wished to explore possible determinants of CF in TCSs median 12 (survey I) and 19 years (survey II) after treatment, in particular the relation to late effects after treatment. PATIENTS AND METHODS: Overall, 812 TCSs treated between 1980 and 1994 provided blood samples (testosterone and luteinizing hormone) and completed questionnaires at survey I (1998-2002) and survey II (2007-2008). Hormone levels were categorized according to quartile thresholds for decadal age groups of controls. Associations between CF and possible risk factors, including the Hospital Anxiety and Depression Scale (HADS), treatment, physical activity, hormone levels, neurotoxicity, and comorbidity, were analyzed by logistic regression. RESULTS: Prevalence of CF increased from 15% at survey I to 27% at survey II (P < 0.001). At survey II, risk for CF was increased three- to four-fold for high levels of neuropathy compared with no neuropathy, and two- to three-fold for high levels of Raynaud-like phenomena, and having testosterone levels in the lowest quartile, while being moderately and highly physically active, had a protective effect. Risk for CF in TCSs with higher levels of HADS-Anxiety and HADS-Depression was increased two- to five-fold, respectively. CONCLUSIONS: The increasing prevalence of CF in TCSs is a novel finding. Lifestyle interventions, early detection and treatment of depression and anxiety, and possibly testosterone substitution might reduce the risk of CF. Extended long-term follow-up seems to be important.

RESUMO

Attempted and achieved post-treatment parenthood, with or without use of assisted reproduction techniques (ARTs), was assessed in Hodgkin's lymphoma survivors treated from 1971-1998, aged below 50 (females) or 65 (males) at diagnosis, aged 18 to 75 at survey. Four treatment groups were constructed: radiotherapy only, low -, medium - and high gonadotoxic chemotherapy (with or without radiotherapy in the three chemotherapy groups). Using Kaplan-Meier estimates, log-rank tests and Cox regression analyses, factors influencing post-treatment parenthood were investigated, with birth of the first child after treatment as the end point. Forty-five per cent (120/269) of males and 50% (91/184) of females reported attempted post-treatment parenthood. Of these, 76 (63%) males and 68 (75%) females had a child without use of ARTs. In addition 10 males and one female achieved post-treatment parenthood with use of ARTs. Treatment group was significantly associated with post-treatment parenthood, with highest probabilities after radiotherapy only and low gonadotoxic chemotherapy. In univariate analyses, age at diagnosis was a significant factor related to post-treatment parenthood in females.

RESUMO

Dietary intake of fish oils, rich in the polyunsaturated fatty acids (PUFAs) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), has given inconsistent results as to their influence on the plasma fibrinogen level (1, 2, 3, 4, 5, 6). In the present study we have examined the effects of various fatty acids, the PUFAs and the saturated fatty acid palmitic acid (PA), alone or combined with the antioxidant vitamin E (Vit.E), on the fibrinogen concentration in the growth medium of human hepatoma (HepG2) cells. Vit.E alone decreased the amount of fibrinogen in the medium in a dose dependent fashion, where fibrinogen was measured as Fibrinopeptide A (FPA) releasable by thrombin. EPA and Vit.E decreased the amount of fibrinogen additively. PUFAs alone increased the fibrinogen concentration in a dose dependent manner. PUFAs combined with a fixed dose of Vit.E decreased the fibrinogen concentration, also dose dependently. OA and PA had an inhibitory effect, both alone and combined with Vit.E. These results indicate that Vit.E may be necessary for PUFAs to have a fibrinogen lowering effect, whereas both OA and PA apparently may decrease the fibrinogen concentration in the cell medium of HepG2 cells, both alone and combined with Vit.E. Possibly, peroxidation of the PUFAs may increase the fibrinogen production, that may be counteracted and reversed by the simultaneous presence of Vit.E.

RESUMO

The protective influence of bovine serum albumin against growth inhibition caused by fatty acids was studied in human hepatoma (HepG2) and immortalized human kidney epithelial (IHKE) cells. In general, growth inhibition by unsaturated fatty acids (0.15 mmol/liter) increased with increasing number of double bonds. For HepG2 cells crude albumin (1 g/100 ml) did not greatly modify growth inhibition by arachidonic, eicosapentaenoic, and docosahexaenoic acid. With oleic, linoleic, and linolenic acids, crude and defatted albumin stimulated cell growth. In contrast, for IHKE cells both albumins counteracted growth inhibition by unsaturated fatty acids to approximately the same extent. When HepG2 cells were cultured in the presence of saturated fatty acids (0.3 mmol/liter), C2, C6, and C8 had no or little inhibitory effect. C10 and C12 inhibited cell growth appreciably, whereas C14, and especially C16, had poor inhibitory effects. Crude albumin counteracted growth inhibition by all these fatty acids. In contrast, defatted albumin had little or no effect (except against C10 and C12), and even increased the growth inhibition by C14 and C16. With unsaturated fatty acids there seemed to be an inverse relationship between cell growth and the concentration of thiobarbituric acid reactive substances (TBARS) in media. Vitamin E abolished growth inhibition (and the increase in TBARS concentration) by unsaturated fatty acids. The complex interaction between fatty acids and albumins calls for great caution when interpreting data on growth effects.

RESUMO

Rape involves mental and physical trauma for the victim. The mental trauma, of which anxiety and guilt are the most prominent, are the most serious. Rape victims are at high risk of developing serious long-term mental problems. We describe various theories about such reactions and the characteristic patterns of phenomena seen in rape victims. The prognosis is best for victims who contact the health service soon after the incident. We discuss the consequences of the above facts in relation to the best ways of providing relevant medical help to rape victims.
