- PURPOSE: This study aimed to evaluate the effect of high intensity (HI) vs low-to-moderate intensity (LMI) exercise on health-related quality of life (HRQoL) up to 18 months after commencement of oncological treatment in patients with breast, colorectal or prostate cancer. In addition, we conducted a comparison with usual care (UC).METHODS: Patients scheduled for (neo)adjuvant oncological treatment (n = 577) were randomly assigned to 6 months of combined resistance and endurance training of HI or LMI. A longitudinal descriptive study (UC) included participants (n = 89) immediately before the RCT started. HRQoL was assessed by EORTC QLQ-C30 at baseline, 3, 6 and 18 months (1 year after completed exercise intervention) follow-up. Linear mixed models were used to study the groups over time.RESULTS: Directly after the intervention, HI scored significant (P = 0.02), but not clinically relevant, higher pain compared with LMI. No other significant difference in HRQoL was found between the exercise intensities over time. Clinically meaningful improvements in HRQoL over time were detected within both exercise intensities. We found favourable significant differences in HRQoL in both exercise intensities compared with UC over time.CONCLUSION: This study adds to the strong evidence of positive effect of exercise and shows that exercise, regardless of intensity, can have beneficial effects on HRQoL during oncological treatment and also for a substantial time after completion of an exercise intervention. In this study, for one year after.IMPLICATIONS FOR CANCER SURVIVORS: Patients can be advised to exercise at either intensity level according to their personal preferences, and still benefit from both short-term and long-term improvements in HRQoL.

- Every year medical researchers make contact with a large number of cancer survivors with the aim of evaluating cancer treatment. For this reason we decided to investigate how Swedish cancer survivors perceived their participation in research studies focusing on the long-term consequences of being a survivor of gynaecological or urinary bladder cancer. Data were collected by means of two study-specific postal questionnaires, both consisting of questions covering physical symptoms, well-being and the experience of being a cancer survivor. Both questionnaires also included questions evaluating the participants' experience of being research subjects. The questionnaires were developed in close co-operation with cancer survivors. The study population consisted of 1068 cancer survivors. Of these, 95% (n=1003) reported that they thought the study was valuable and 54% (n=559) that they had been positively affected by participating. Four per cent (n=39) expressed that they had been negatively affected by their participation in the study. The vast majority of the cancer survivors thought that participating in their particular study was valuable.

- Although physical exercising has great benefits, little is known regarding factors of significance for cancer survivors to continue exercising within their rehabilitation. The objective was to describe factors experienced to be of significance for cancer survivors to continue with water-exercising long-term after breast cancer surgery. Women (n=29) who had undergone breast cancer surgery (mastectomy 79%, axillary surgery 86%, and radiotherapy 86%) for median (md) 13 (25th-75th percentile 3-21.5) was followed up regarding their rehabilitation, arm function Disabilities of Arm Shoulder and Hand (md 14, IQR 7-32), EQ-5D score (md 0.8, IQR 0.73-1.0) and quality of life EQ health barometer (md 80, IQR 64-95). We performed qualitative focus-group interviews regarding the womens views (n=24). The women had participated in water-exercising 1-46 semesters, md 8 (25th-75th percentile 3-21.5) semesters. Nearly all, 97%, participated in the water-exercising group every week, and 21 (72%) had participated in the water-exercising group at least half of the time since their breast cancer surgery, without complications. The women experienced that factors of significance to continue with water-exercising were the convenience of easily modified weightless exercising in the water, social interaction, and access to a private dressing room. These factors would be important to consider to encourage continuing in exercising.

- PURPOSE: We aimed to investigate the effects of reallocating sedentary time to an equal amount of light (LPA) or moderate-to-vigorous intensity physical activity (MVPA) on cancer-related fatigue and health-related quality of life (HRQoL) in patients with breast cancer. We also aimed to determine the daily amount of sedentary time needed to be reallocated to LPA or MVPA to produce minimal clinically important changes in these outcomes.METHODS: Pooled baseline data from three studies were used, including women with breast cancer who participated in the Phys-Can project. Fatigue was assessed with the Multidimensional Fatigue Inventory questionnaire (MFI; five dimensions, 4-20 scale) and HRQoL with the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30; 0-100 scale). Sedentary time and physical activity were measured with accelerometry. Isotemporal substitution modelling was used for the analyses.RESULTS: Overall, 436 participants (mean age 56 years, fatigue 11 [MFI], HRQoL 66 [EORTC QLQ-C30], LPA 254 min/day, MVPA 71 min/day) were included. Fatigue significantly decreased in two MFI dimensions when reallocating 30 min/day of sedentary time to LPA: reduced motivation and reduced activity (β = - 0.21). Fatigue significantly decreased in three MFI dimensions when reallocating 30 min/day of sedentary time to MVPA: general fatigue (β = - 0.34), physical fatigue (β = - 0.47) and reduced activity (β = - 0.48). To produce minimal clinically important changes in fatigue (- 2 points on MFI), the amount of sedentary time needed to be reallocated to LPA was ≈290 min/day and to MVPA was ≥ 125 min/day. No significant effects were observed on HRQoL when reallocating sedentary time to LPA or MVPA.CONCLUSIONS: Our results suggest that reallocating sedentary time to LPA or MVPA has beneficial effects on cancer-related fatigue in patients with breast cancer, with MVPA having the greatest impact. In relatively healthy and physically active breast cancer populations, a large amount of time reallocation is needed to produce clinically important changes. Future studies are warranted to evaluate such effects in broader cancer populations.TRIAL REGISTRATION: NCT02473003 (10/10/2014) and NCT04586517 (14/10/2020).

- What’s known on the subject? and What does the study add?Functional gastrointestinal symptoms and problems are common after radical cystectomy with urinary diversion. This study adds new important epidemiological data on this group of symptoms. OBJECTIVE: To describe and compare long-term defecation disturbances in patients who had undergone a cystectomy due to urinary bladder cancer with non-continent urostomies, continent reservoirs and orthotopic neobladder urinary diversions. PATIENTS AND METHODS: During their follow-up we attempted to contact all men and women aged 30–80 years who had undergone cystectomy and urinary diversion at seven Swedish hospitals. During a qualitative phase we identified defecation disturbances as a distressful symptom and included this item in a study-specific questionnaire together with free-hand comments. The patients completed the questionnaire at home. Outcome variables were dichotomized and the results are presented as relative risks with 95% confidence interval. RESULTS: The questionnaire was returned from 452 (92%) of 491 identified patients. Up to 30% reported problems with the physiological emptying process of stool (bowel movement, sensory rectal function, awareness of need for defecation, motoric rectal and anal function, straining ability). A sense of decreased straining capacity was reported by 20% of the men and women with non-continent urostomy and 14% and 8% of those with continent reservoirs and orthotopic neobladders, respectively. CONCLUSIONS: Of the cystectomized individuals 30% reported problems with the physiological emptying process of stool (bowel movement, sensory rectal function, awareness of need for defecation, motoric rectal and anal function, straining ability). Those wanting to improve the situation for bladder cancer survivors may consider communicating before surgery the possibility of stool-emptying problems, and asking about them after surgery.

- ObjectivesThis study aimed to explore psychological symptoms in widowed parents with minor children, 2–4 years after the death of their partner. A second aim was to examine the associations between psychological symptoms and nonmodifiable and modifiable illness and healthcare-related factors.MethodsA cross-sectional survey study on widowed parents with minor children after the loss of a partner to cancer. In total, 42 parents completed an online questionnaire including instruments for assessing symptoms of anxiety, depression, grief rumination, prolonged grief, and posttraumatic stress. Descriptive statistics, Spearman's correlation coefficients, Mann–Whitney U tests and Kruskal–Wallis tests were used to analyze differences in symptomology based on modifiable and nonmodifiable factors.ResultsParents reported moderate–severe symptoms of anxiety, posttraumatic stress, and depression. Reporting having received more information during the partner's illness regarding how the illness could affect the partner's somatic and psychological health and where to turn for support were associated with fewer psychological symptoms.ConclusionsA substantial proportion of widowed parents with minor children reported a moderate–severe symptom burden regarding depression, anxiety, and posttraumatic stress, and less so with prolonged grief symptoms. This study also highlighted the value of receiving information from healthcare personnel regarding the somatic and psychological effects of a partner's illness and where widowed parents can turn for support.

- Background: Resistance towards endocrine therapy is a great concern in breast cancer treatment and may partly be explained by the activation of compensatory signaling pathways. The aim of the present study was to investigate if the insulin-like growth factor-1 receptor (IGF1R) signaling pathway was activated or deregulated in breast cancer patients and to explore if any of the markers were prognostic, with or without adjuvant tamoxifen. This signaling pathway has been suggested to cause estrogen independent cell growth and thus contribute to resistance to endocrine treatment in estrogen receptor (ER) positive breast cancer. Methods: The protein expression of IGF1R, phosphorylated Mammalian Target of Rapamycin (p-mTOR) and phosphorylated S6 ribosomal protein (p-S6rp) were investigated by immunohistochemistry using tissue microarrays in two patient cohorts. Cohort I (N = 264) consisted of mainly postmenopausal women with stage II breast cancer treated with tamoxifen for 2 years irrespective of ER status. Cohort II (N = 206) consisted of mainly medically untreated, premenopausal patients with node-negative breast cancer. Distant disease-free survival (DDFS) at 5 years was used as end-point for survival analyses. Results: We found that lower IGF1R expression was associated with worse prognosis for tamoxifen treated, postmenopausal women (HR = 0.70, 95% CI = 0.52 - 0.94, p = 0.016). The effect was seen mainly in ER-negative patients where the prognostic effect was retained after adjustment for other prognostic markers (adjusted HR = 0.49, 95% CI = 0.29 - 0.82, p = 0.007). Expression of IGF1R was associated with ER positivity (p less than 0.001) in the same patient cohort. Conclusions: Our results support previous studies indicating that IGF1R positivity reflects a well differentiated tumor with low metastatic capacity. An association between lack of IGF1R expression and worse prognosis was mainly seen in the ER-negative part of Cohort I. The lack of co-activation of downstream markers (p-mTOR and p-S6rp) in the IGF1R pathway suggested that the prognostic effect was not due to complete activation of this pathway. Thus, no evidence could be found for a compensatory function of IGF1R signaling in the investigated cohorts.

- Background. Oestrogen receptor (ER) status is important for the choice of systemic treatment of breast cancer patients. However, most data from randomised trials on the effect of adjuvant endocrine therapy according to ER status are based on the cytosol methods. Comparisons with immunohistochemical methods have given similar results. The aim of the present study was to examine whether different ER antibodies and heat-induced epitope retrieval (HIER) methods influence the prevalence of ER-positivity in primary breast cancer. Material and methods. This study is based on patients included in a clinical trial designed to compare the effect of two years of adjuvant tamoxifen versus no adjuvant systemic treatment in premenopausal women. From 1986 to 1991, 564 patients from two study centres in Sweden were enrolled and randomised. Patients were randomised independently of ER status. In the present study, ER status was assessed on tissue microarrays with the three different ER antibody/HIER combinations: 1D5 in citrate pH 6 (n = 390), SP1 in Tris pH 9 (n = 390) and PharmDx in citrate pH 6 (n = 361). Results. At cut-offs of 1% and 10%, respectively, the prevalence of ER-positivity was higher with SP1 (75% and 72%) compared with 1D5 (68% and 66%) and PharmDx (66% and 62%). At these cut-offs, patients in the discordant groups (SP1-positive and 1D5-negative) seem to have a prognosis intermediate between those of the double-positive and double-negative groups. Comparison with the ER status determined by the cytosol-based methods in the discordant group also showed an intermediate pattern. The repeatability was good for all antibodies and cut-offs, with overall agreement andgt;= 93%. Conclusion. The present study shows that the choice of antibody and HIER method influences the prevalence of ER-positivity. We suggest that this be taken into consideration when choosing a cut-off for clinical decision making.

- Purpose: To investigate the clinical management and outcome of patients with muscle-invasive bladder cancer with clinical lymph node involvement, using longitudinal nationwide population-based data.Methods: In the Bladder Cancer Data Base Sweden (BladderBaSe), treatment and survival in patients with urinary bladder cancer clinical stage T2-T4 N + M0 diagnosed between 1997 and 2014 was investigated. Patients´ characteristics were studied in relation to TNM classification, curative or palliative treatment, cancer-specific (CSS) and overall survival (OS). Age at diagnosis was categorised as ≤60, 61-70, 71-80 and >80 years, and time periods were stratified as follows: 1997-2001, 2002-2005, 2006-2010 and 2011-2014.Results: There were 786 patients (72% males) with a median age of 71 years (interquartile range = 64-79 years). The proportion of patients with high comorbidity increased over time. Despite similar low comorbidity, curative treatment was given to 44% and to 70% of those in older (>70 years) and younger age groups, respectively. Curative treatment decreased over time, but chemotherapy and cystectomy increased to 25% during the last time period. Patients with curative treatment had better survival compared to those with palliative treatment, both regarding CSS and OS in the whole cohort and in all age groups.Conclusions: The low proportion of older patients undergoing treatment with curative intent, despite no or limited comorbidity, indicates missed chances of treatment with curative intent. The reasons for an overall decrease in curative treatment over time need to be analysed and the challenge of coping with an increasing proportion of node-positive patients with clinically significant comorbidity needs to be met.

- Objective To study how patients with urinary bladder cancer (UBC) with previous or concomitant other primary cancers (OPCs) were treated, and to investigate their prognosis. Patients And Methods Using nationwide population-based data in the Bladder Cancer Data Base Sweden (BladderBaSe), we analysed the probability of treatment with curative intent, and UBC-specific and overall survival (OS) in patients with UBC diagnosed in the period 1997-2014 with or without OPC. The analyses considered the patient's characteristics, UBC tumour stage at diagnosis, and site of OPC. Results There were 38 689 patients, of which 9804 (25%) had OPCs. Those with synchronous OPCs more often had T2 and T3 tumours and clinically distant disease at diagnosis than those with UBC only. Patients with synchronous prostate cancer, female genital cancer and lower gastro-intestinal cancer were more often treated with curative intent than patients with UBC only. When models of survival were adjusted for age at diagnosis, marital status, education, year of diagnosis, Charlson Comorbidity Index and T-stage, UBC-specific survival was similar to patients with UBC only, but OS was lower for patients with synchronous OPC, explained mainly by deaths in OPC primaries with a bad prognosis. Conclusions OPC is common in patients with UBC. Treatment for UBC, after or in conjunction with an OPC, should not be neglected and carries just as high a probability of success as treatment in patients with UBC only. The needs of patients with UBC and OPC, and optimisation of their treatment considering their complicated disease trajectory are important areas of research.
