Abstract
This article reports on how the introduction of patient-generated health data affects the nurses' and patients' data work and unpacks how new forms of data collection trigger shifts in the work with data through translation work. The article is based on a 2.5-year case study examining data work of nurses and patients at a cancer rehabilitation clinic at a Swedish Hospital in which patient-generated health data are gathered by patients and then used outside and within clinical practice for decision-making. The article reports on how data are prepared and translated, that is, made useful by the nurses and patients. Using patient-generated health data alters the data work and how the translation of data is performed. The shift in work has three components: (1) a shift in question tactics, (2) a shift in decision-making, and (3) a shift in distribution. The data become mobile, and the data work becomes distributed when using patient-generated health data as an active part of care.

Abstract
Purpose: All types of surgery are associated with complications. The debate is ongoing whether robot-assisted radical prostatectomy can lower this risk compared to open surgery. The objective of the present study was to evaluate post-operative adverse events leading to readmissions, using clinical records to classify these adverse events systematically. Materials and methods: A prospective controlled trial of men who underwent robot-assisted laparoscopic (RALP) or retropubic radical prostatectomy (RRP) at 14 departments of Urology (LAPPRO) between 2008 and 2011. Data on all readmissions within 3 months of surgery were collected from the Patient registry, Swedish Board of Health and Welfare. For each readmission the highest Clavien-Dindo grade was listed. Results: A total of 4003 patients were included in the LAPPRO trial and, after applying exclusion criteria, 3706 patients remained for analyses. The results showed no statistically significant difference in the overall readmission rates (8.1 vs. 7.1%) or readmission due to major complications (Clavien-Dindo ≥3b, 1.7 vs. 1.9%) between RALP and RRP within 90 days after surgery. Patients subjected to lymph-node dissection (LND) had twice the risk for readmission as men not undergoing LND, irrespective RALP or RRP technique. Blood transfusion was significantly more frequent during and within 30 days of RRP surgery (16 vs. 4%). Abdominal symptoms were more common after RALP. Conclusions: There is a substantial risk for hospital readmission after prostate-cancer surgery, regardless of technique; although major complications are rare. Regardless of surgical technique, attention should be focused on specific types of complications.

Abstract
BACKGROUND Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term follow-up is sparse. METHODS We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated. We evaluated the prognostic value of histopathological measures with a Cox proportional-hazards model. RESULTS By December 31, 2017, a total of 261 of the 347 men in the radical-prostatectomy group and 292 of the 348 men in the watchful-waiting group had died; 71 deaths in the radical-prostatectomy group and 110 in the watchful-waiting group were due to prostate cancer (relative risk, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001; absolute difference in risk, 11.7 percentage points; 95% CI, 5.2 to 18.2). The number needed to treat to avert one death from any cause was 8.4. At 23 years, a mean of 2.9 extra years of life were gained with radical prostatectomy. Among the men who underwent radical prostatectomy, extracapsular extension was associated with a risk of death from prostate cancer that was 5 times as high as that among men without extracapsular extension, and a Gleason score higher than 7 was associated with a risk that was 10 times as high as that with a score of 6 or lower (scores range from 2 to 10, with higher scores indicating more aggressive cancer). CONCLUSIONS Men with clinically detected, localized prostate cancer and a long life expectancy benefited from radical prostatectomy, with a mean of 2.9 years of life gained. A high Gleason score and the presence of extracapsular extension in the radical prostatectomy specimens were highly predictive of death from prostate cancer.

Abstract
Preclinical studies indicate that an optimal diet during pelvic radiotherapy may be able to prevent radiation-induced survivorship diseases that diminish cancer survivors' intestinal health. We do not yet know what this optimal diet might be because scientific studies needed to determine what dietary advice might best be given to patients during treatment. Oncology clinics in Sweden were contacted to determine the nature of dietary advice given to gynaecological and prostate cancer patients at each clinic before, during and after radiotherapy. Reports from these clinics revealed that dietary advice given to patients differs from one clinic to another. This was as expected, since it was known that the scientific evidence needed to identify the best possible diet is not yet available. Clinical studies of the effects of different diets are urgently needed if we are to prevent survivorship diseases that decrease intestinal health.

Abstract
PURPOSE To find out what organs and doses are most relevant for 'radiation-induced urgency syndrome' in order to derive the corresponding dose-response relationships as an aid for avoiding the syndrome in the future. MATERIAL AND METHODS From a larger group of gynecological cancer survivors followed-up 2-14 years, we identified 98 whom had undergone external beam radiation therapy but not brachytherapy and not having a stoma. Of those survivors, 24 developed urgency syndrome. Based on the loading factor from a factor analysis, and symptom frequency, 15 symptoms were weighted together to a score interpreted as the intensity of radiation-induced urgency symptom. On reactivated dose plans, we contoured the small intestine, sigmoid colon and the rectum (separate from the anal-sphincter region) and we exported the dose-volume histograms for each survivor. Dose-response relationships from respective risk organ and urgency syndrome were estimated by fitting the data to the Probit, RS, LKB and gEUD models. RESULTS The rectum and sigmoid colon have steep dose-response relationships for urgency syndrome for Probit, RS and LKB. The dose-response parameters for the rectum were D50: 51.3, 51.4, and 51.3 Gy, γ50 = 1.19 for all models, s was 7.0e-09 for RS and n was 9.9 × 107 for LKB. For Sigmoid colon, D50 were 51.6, 51.6, and 51.5 Gy, γ50 were 1.20, 1.25, and 1.27, s was 2.8 for RS and n was 0.079 for LKB. CONCLUSIONS Primarily the dose to sigmoid colon as well as the rectum is related to urgency syndrome among gynecological cancer survivors. Separate delineation of the rectum and sigmoid colon in order to incorporate the dose-response results may aid in reduction of the incidence of the urgency syndrome.

Abstract
BACKGROUND AND PURPOSE Traditionally, elastase has been used to study exocrine activity of the pancreas in patients with chronic pancreatitis and cystic fibrosis, and calprotectin as a marker for gut-wall inflammation in patients with inflammatory bowel disease. The aim of the study was to find out whether elastase and calprotectin could be used as inflammatory markers for radiation-induced gut wall injury of the distal bowel. MATERIAL AND METHODS Adult male mice were exposed to two, three, or four fractions of 6 Gy or 8 Gy irradiation to the sigmoid and rectum of the large bowel, using a linear accelerator. Fecal samples were collected from mice at 1, 3, and 6 weeks post-irradiation. The fecal levels of elastase and calprotectin were analyzed using ELISA. RESULTS Three and 6 weeks after irradiation, we found a dose-effect relationship between dose of ionizing radiation and the fecal level of elastase; that is significantly higher levels of elastase were observed in mice that had received a high irradiation dose. We also found that irradiated mice hosted in the same cage had a comparable level (either high or low) of elastase. No significant differences were observed from the calprotectin data. CONCLUSIONS We found a clear association between the dose of ionizing radiation to the distal colon and the level of elastase in the fecal samples.

Abstract
BACKGROUND The adoption of robot-assisted laparoscopic radical prostatectomy (RALP) has increased rapidly, despite lack of conclusive evidence of its superiority regarding long-term outcomes over open retropubic RP (RRP). In 2015, we reported on 12-mo follow-up from the LAPPRO trial showing a moderate advantage of RALP regarding erectile dysfunction. No significant differences were seen for urinary incontinence or surgical margin status. OBJECTIVE To present patient-reported functional outcomes and recurrent and residual disease at 24-mo follow-up from the prospective multicenter LAPPRO trial. DESIGN, SETTING, AND PARTICIPANTS A total of 4003 patients with clinically localized prostate cancer were recruited from 14 Swedish centers, seven performing RALP and seven RRP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Data were only analyzed for patients operated on by surgeons with >100 prior RPs. Adjusted odds ratios (AORs) were calculated using logistic regression, with adjustment for differences in patient mix. RESULTS AND LIMITATIONS At 24 mo, there was a significant difference in erectile dysfunction in favor of RALP (68% vs 74%; AOR 0.72, 95% confidence interval [CI] 0.57-0.91; p=0.006). No significant difference was observed for incontinence (19% vs 16%; AOR 1.29, 95% CI 1.00-1.67; p=0.053) or recurrent or residual disease (13% vs 13%; AOR 0.79, 95% CI 0.59-1.07; p=0.13). We did not adjust for individual surgeon volume and experience, which is a potential limitation. CONCLUSIONS Extended follow-up corroborated our previous report at 12 mo of a persistent RALP benefit regarding potency. PATIENT SUMMARY LAPPRO is a Swedish trial comparing two different prostate cancer surgical techniques (robotic compared to open). At 24-mo follow-up after surgery there was a moderate advantage for the robotic technique regarding erectile dysfunction (potency), while there was a small but not significant difference in urinary leakage in favor of open surgery. We did not find any difference regarding cancer relapse.

Abstract
PURPOSE To investigate whether inter-institutional cohort analysis uncovers more reliable dose-response relationships exemplified for late rectal bleeding (LRB) following prostate radiotherapy. MATERIAL AND METHODS Data from five institutions were used. Rectal dose-volume histograms (DVHs) for 989 patients treated with 3DCRT or IMRT to 70-86.4 Gy@1.8-2.0 Gy/fraction were obtained, and corrected for fractionation effects (α/β = 3 Gy). Cohorts with best-fit Lyman-Kutcher-Burman volume-effect parameter a were pooled after calibration adjustments of the available LRB definitions. In the pooled cohort, dose-response modeling (incorporating rectal dose and geometry, and patient characteristics) was conducted on a training cohort (70%) followed by final testing on the remaining 30%. Multivariate logistic regression was performed to build models with bootstrap stability. RESULTS Two cohorts with low bleeding rates (2%) were judged to be inconsistent with the remaining data, and were excluded. In the remaining pooled cohorts (n = 690; LRB rate = 12%), an optimal model was generated for 3DCRT using the minimum rectal dose and the absolute rectal volume receiving less than 55 Gy (AUC = 0.67; p = 0.0002; Hosmer-Lemeshow p-value, pHL = 0.59). The model performed nearly as well in the hold-out testing data (AUC = 0.71; p < 0.0001; pHL = 0.63), indicating a logistically shaped dose-response. CONCLUSION We have demonstrated the importance of integrating datasets from multiple institutions, thereby reducing the impact of intra-institutional dose-volume parameters explicitly correlated with prescription dose levels. This uncovered an unexpected emphasis on sparing of the low to intermediate rectal dose range in the etiology of late rectal bleeding following prostate radiotherapy.

Abstract
BACKGROUND Robot-assisted radical prostatectomy (RARP) for prostate cancer (PCa) treatment has been widely adopted with limited evidence for long-term (>5 yr) oncologic efficacy. OBJECTIVE To evaluate long-term oncologic outcomes following RARP. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of 885 patients who underwent RARP as monotherapy for PCa between 2002 and 2006 in a single European centre and followed up until 2016. INTERVENTION RARP as monotherapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Biochemical recurrence (BCR)-free survival (BCRFS), salvage therapy (ST)-free survival (STFS), prostate cancer-specific survival (CSS), and overall survival (OS) were estimated using the Kaplan-Meier method, and event-time distributions were compared using the log-rank test. Variables predictive of BCR and ST were identified using Cox proportional hazards models. RESULTS AND LIMITATIONS We identified 167 BCRs, 110 STs, 16 PCa-related deaths, and 51 deaths from other/unknown causes. BCRFS, STFS, CSS, and OS rates were 81.8%, 87.5%, 98.5%, and 93.0%, respectively, at median follow-up of 10.5 yr. On multivariable analysis, the strongest independent predictors of both BCR and ST were preoperative Gleason score, pathological T stage, positive surgical margins (PSMs), and preoperative prostate-specific antigen. PSM >3mm/multifocal but not ≤3mm independently affected the risk of both BCR and ST. Study limitations include a lack of centralised histopathologic reporting, lymph node and post-operative tumour volume data in a historical cohort, and patient-reported outcomes. CONCLUSIONS RARP appears to confer effective long-term oncologic efficacy. The risk of BCR or ST is unaffected by ≤3mm PSM, but further follow-up is required to determine any impact on CSS. PATIENT SUMMARY Robot-assisted surgery for prostate cancer is effective 10 yr after treatment. Very small (<3mm) amounts of cancer at the cut edge of the prostate do not appear to impact on recurrence risk and the need for additional treatment, but it is not yet known whether this affects the risk of death from prostate cancer.

Abstract
OBJECTIVE Cancer treatment may result in various effects that last long after treatment has been concluded. The purpose of this study was to explore to what extent scars affect adolescents and young adults postcancer treatment. METHODS In this population-based study, a study-specific questionnaire was developed by a method used in several previous investigations carried out by our research group, Clinical Cancer Epidemiology. Question development involved expert validation by professionals from oncology units, midwives, epidemiologists, and statisticians. The questionnaire was developed in collaboration with adolescent and young adult cancer survivors. The topics covered in the questionnaire were as follows: psychosocial health, body image and sexuality, fertility, education, work, and leisure. The web-based questionnaire was sent to teenage and young adult cancer survivors and matched controls in Sweden. RESULTS In this study, the relative risk of feeling less attractive due to scars was higher both for female cancer survivors RR 1.48, CI 1.05-2.08 and male cancer survivors RR 1.90, CI 1.15-3.13 compared to controls. The feeling of attractiveness was negatively related to the size of scars in both cancer and control groups. In a logistic regression analysis, significant associations were found between age, education, exercise, depression, and the feeling of low attractiveness due to scars. CONCLUSIONS The results of this study provide a basis for care interventions for teenage and young adult cancer patients during and after cancer treatment. Further research is needed on care interventions to reduce, if possible, the impact of scars.

Abstract
Background Urologists are frequently confronted with questions of urinary bladder cancer (UBC) patients about what they can do to improve their prognosis. Unfortunately, it is largely unknown which lifestyle factors can influence prognosis. Objective To systematically review the available evidence on the association between body mass index (BMI), diet, dietary supplements, and physical activity and UBC prognosis. Methods We searched PubMed and Embase up to May 2017. We included thirty-one articles reporting on observational and randomized controlled trials investigating BMI, diet and dietary supplements in relation to recurrence, progression, cancer-specific or all-cause mortality in UBC patients. Results In non-muscle invasive bladder cancer (NMIBC) patients, both overweight (3 studies, pooled hazard ratio (HR) 1.29, 95% CI 1.05-1.58, I2 = 0%) as well as obesity (3 studies, pooled HR 1.82, 95% CI 1.12-2.95, I2 = 79%) were associated with increased risk of recurrence when compared to normal weight. No association of BMI with risk of progression was found. Results for BMI and prognosis in muscle-invasive or in all stages series were inconsistent. Observational studies on diet and randomized controlled trials with dietary supplements showed inconsistent results. No studies on physical activity and UBC prognosis have been published to date. Conclusions Evidence for an association of lifestyle factors with UBC prognosis is limited, with some evidence for an association of BMI with risk of recurrence in NMIBC. Well-designed, prospective studies are needed to develop evidence-based guidelines on this topic.

Abstract
This article presents preliminary findings on how the introduction of patient-generated health data (PGHD) triggers changes during patient-nurse consultations. This article builds on a two-year case study, examining the work practice at a cancer rehabilitation clinic at a Swedish Hospital using PGHD. The study focuses on how nurses' use data, gathered by patients with a mobile phone app, during consultations. The use of PGHD introduce a change in the translation work, the work of turning rich patient descriptions and transform them into data, during the consultation for documentation and clinical decision-making. This change affects precision, questions asked and the use of visualizations as well as the patient-nurse decision making.

Abstract
BACKGROUND Prostate-cancer diagnosis increases the risk for psychiatric morbidity and suicide. Thoughts about one's own death could indicate need for psychiatric care among men with localized prostate cancer. We studied the prevalence and predictors of thoughts about own death among men with prostate cancer. METHODS Of the 3930 men in the prospective, multi-centre LAPPRO-trial, having radical prostatectomy, 3154 (80%) answered two study-specific questionnaires, before and three months after surgery. Multivariable prognostic models were built with stepwise regression and Bayesian Model Averaging. RESULTS After surgery 46% had thoughts about their own death. Extra-prostatic tumor-growth [Adjusted Odds-Ratio 2.06, 95% Confidence Interval 1.66-2.56], university education [OR 1.66, CI 1.35-2.05], uncertainty [OR 2.20, CI 1.73-2.82], low control [OR 2.21, CI 1.68-2.91], loneliness [OR 1.75, CI 1.30-2.35], being a burden [OR 1.59, CI 1.23-2.07], and crying [OR 1.55, CI 1.23-1.96] before surgery predicted thoughts about one's own death after surgery. CONCLUSIONS We identified predictors for thoughts about one's own death after prostate cancer diagnosis and surgery. These factors may facilitate the identification of psychiatric morbidity and those who might benefit from psychosocial support already during primary treatment.

OBJECTIVE Studies indicate that social constraints (barriers to emotional expression) may be a risk factor for psychological morbidity. We aimed to investigate the association between prostate cancer-related social constraints and psychological well-being following prostate cancer surgery. METHODS In a group of 3478 partnered patients, participating in the Laparoscopic Prostatectomy Robot Open trial, a prospective multicenter comparative study of robot-assisted laparoscopic and retropubic radical prostatectomy for prostate cancer, we used log-binomial regression analysis to investigate the links between prostate cancer-related social constraints at 3 months after surgery and psychological well-being at 12 and 24 months. RESULTS A total of 1086 and 1093 men reported low well-being at 12 and 24 months, respectively. Prostate cancer-related social constraints by partner predicted low psychological well-being at 12 months (adjusted RR: 1.4; 95% CI, 1.1-1.9) and by others (adjusted RR: 1.9; 95% CI, 1.1-3.5). Intrusive thoughts mediated the association. CONCLUSIONS Negative responses from the social environment, especially from partner to talking about the prostate cancer experience affected patients' psychological well-being 2 years after radical prostatectomy. Results emphasize the importance of helping patients mobilize psychosocial resources within their social network, especially among those with a lack of quality psychosocial support.

Abstract
Purpose To determine the effect of comorbidity on prostate cancer (PCa)-specific mortality across treatment types. Patients and Methods These are the results of a population-based observational study in Sweden from 1998 to 2012 of 118,543 men who were diagnosed with PCa with a median follow-up of 8.3 years (interquartile range, 5.2 to 11.5 years) until death from PCa or other causes. Patients were categorized by patient characteristics (marital status, educational level) and tumor characteristics (serum prostate-specific antigen, tumor grade and clinical stage) and by treatment type (radical prostatectomy, radical radiotherapy, androgen deprivation therapy, and watchful waiting). Data were stratified by Charlson comorbidity index (0, 1, 2, or ≥ 3). Mortality from PCa and other causes and after stabilized inverse probability weighting adjustments for clinical patient and tumor characteristics and treatment type was determined. Kaplan-Meier estimates and Cox proportional hazards regression models were used to calculate hazard ratios. Results In the complete unadjusted data set, we observed an effect of increased comorbidity on PCa-specific and other-cause mortality. After adjustments for patient and tumor characteristics, the effect of comorbidity on PCa-specific mortality was lost but maintained for other-cause mortality. After additional adjustment for treatment type, we again failed to observe an effect for comorbidity on PCa-specific mortality, although it was maintained for other-cause mortality. Conclusion This large observational study suggests that comorbidity affects other cause-mortality but not PCa-specific- mortality after accounting for patient and tumor characteristics and treatment type. Regardless of radical treatment type (radical prostatectomy or radical radiotherapy), increasing comorbidity does not seem to significantly affect the risk of dying from PCa. Consequently, differences in oncologic outcomes that were observed in population-based comparative effectiveness studies of PCa treatments may not be a result of the varying distribution of comorbidity among treatment groups.

Abstract
A deeper understanding of the radiation-induced pathophysiological processes that develop in the gut is imperative to prevent, alleviate, or eliminate cancer survivorship diseases after radiotherapy to the pelvic area. Most rodent models of high-dose gastrointestinal radiation injury are limited by high mortality. We therefore established a model that allows for the delivering of radiation in fractions at high doses while maintaining long-term survival. Adult male C57/BL6 mice were exposed to small-field irradiation, restricted to 1.5 cm of the colorectum using a linear accelerator. Each mouse received 6 or 8 Gy, two times daily in 12-h intervals in two, three, or four fractions. Acute cell death was examined at 4.5 h postirradiation and histological changes at 6 wk postirradiation. Another group was given four fractions of 8 Gy and followed over time for development of visible symptoms. Irradiation caused immediate cell death, mainly limited to the colorectum. At 6 wk postirradiation, several crypts displayed signs of radiation-induced degeneration. The degenerating crypts were seen alongside crypts that appeared perfectly healthy. Crypt survival was reduced after the fourth fraction regardless of dose, whereas the number of macrophages increased. Angiogenesis was induced, likely as a compensatory mechanism for hypoxia. Four months postirradiation, mice began to show radiation-induced symptoms, and histological examination revealed an extensive crypt loss and fibrosis. Our model is uniquely suitable for studying the long-term trajectory and underlying mechanisms of radiation-induced gastrointestinal injury.NEW & NOTEWORTHY A novel mouse model for studying the long-term trajectory of radiation-induced gut injury. The method allows for the use of high doses and multiple fractions, with minor impact on animal health for at least 3 mo. Crypt loss and a slow progression of fibrosis is observed. Crypt degeneration is a process restricted to isolated crypts. Crypt degeneration is presented as a convenient proxy endpoint for long-term radiation-induced gut injury.

Abstract
BACKGROUND A majority of cancer-bereaved siblings report long-term unresolved grief, thus it is important to identify factors that may contribute to resolving their grief. OBJECTIVE To identify modifiable or avoidable family and care-related factors associated with unresolved grief among siblings two to nine years post loss. DESIGN This is a nationwide Swedish postal survey. MEASUREMENTS Study-specific questions and the standardized instrument Hospital Anxiety and Depression Scale. Primary outcome was unresolved grief, and family and care-related factors were used as predictors. SETTING/PARTICIPANTS Cancer-bereaved sibling (N = 174) who lost a brother/sister to childhood cancer during 2000-2007 in Sweden (participation rate 73%). Seventy-three were males and 101 females. The age of the siblings at time of loss was 12-25 years and at the time of the survey between 19 and 33 years. RESULTS Several predictors for unresolved grief were identified: siblings' perception that it was not a peaceful death [odds ratio (OR): 9.86, 95% confidence interval (CI): 2.39-40.65], limited information given to siblings the last month of life (OR: 5.96, 95% CI: 1.87-13.68), information about the impending death communicated the day before it occurred (OR: 2.73, 95% CI: 1.02-7.33), siblings' avoidance of the doctors (OR: 3.22, 95% CI: 0.75-13.76), and lack of communication with family (OR: 2.86, 95% CI: 1.01-8.04) and people outside the family about death (OR: 5.07, 95% CI: 1.64-15.70). Depressive symptoms (OR: 1.27, 95% CI: 1.12-1.45) and time since loss (two to four years: OR: 10.36, 95% CI: 2.87-37.48 and five to seven years: OR: 8.36, 95% CI: 2.36-29.57) also predicted unresolved grief. Together, these predictors explained 54% of the variance of unresolved grief. CONCLUSION Siblings' perception that it was not a peaceful death and poor communication with family, friends, and healthcare increased the risk for unresolved grief among the siblings.

Abstract
Purpose Previous research shows that the death of a parent places children at risk for a number of negative outcomes. The role of trust in health care at the end of life has been acknowledged as crucial for patients and adult family members. However, the consequences of children’s distrust in the care provided to their parents remain unknown. Therefore, we investigated the negative long-term outcomes of cancer-bereaved sons’ and daughters’ distrust in the care that was provided to a dying parent. Methods We used a population-based nationwide survey to investigate self-reported distrust in the care provided and possible negative outcomes in 622 (73%) participants who had lost a parent as a result of cancer 6 to 9 years earlier, at ages 13 to 16 years. All participants were 18 years or older at the time of the survey. Results In those who reported no or little trust (ie, distrust) in the health care provided to their dying parents, we found statistically significantly higher risks of various negative outcomes at the time of survey: bitterness toward health care professionals for not having done everything that was possible (crude risk ratio [RR], 3.5; 95% CI, 2.3 to 5.1) and for having stopped treatment (RR, 3.4; 95% CI, 2.1 to 6.0), self-destructiveness (eg, self-injury [RR, 1.7; 95% CI, 1.2 to 2.4]), and psychological problems (eg, moderate to severe depression according to the Patient Health Questionnaire–9 [RR, 2.3; 95% CI, 1.5 to 3.5]). Conclusion In cancer-bereaved former adolescents, distrust in the health care provided to the dying parent is associated with a higher risk of negative long-term outcomes. The health care professionals involved in this care might play an important role in safeguarding the trust of adolescents.

Abstract
Background: Gene expression profiling has made considerable contributions to our understanding of cancer biology and clinical care. This study describes a novel gene expression signature for breast cancer-specific survival that was validated using external datasets.Methods: Gene expression signatures for invasive breast carcinomas (mainly luminal B subtype) corresponding to 136 patients were analyzed using Cox regression, and the effect of each gene on disease-specific survival (DSS) was estimated. Iterative Bayesian model averaging was applied on multivariable Cox regression models resulting in an 18-marker panel, which was validated using three external validation datasets. The 18 genes were analyzed for common pathways and functions using the Ingenuity Pathway Analysis software. This study complied with the REMARK criteria.Results: The 18-gene multivariable model showed a high predictive power for DSS in the training and validation cohort and a clear stratification between high- and low-risk patients. The differentially expressed genes were predominantly involved in biological processes such as cell cycle, DNA replication, recombination, and repair. Furthermore, the majority of the 18 genes were found to play a pivotal role in cancer.Conclusions: Our findings demonstrated that the 18 molecular markers were strong predictors of breast cancer-specific mortality. The stable time-dependent area under the ROC curve function (AUC(t)) and high C-indices in the training and validation cohorts were further improved by fitting a combined model consisting of the 18-marker panel and established clinical markers.Impact: Our work supports the applicability of this 18-marker panel to improve clinical outcome prediction for breast cancer patients.

Abstract
BACKGROUND Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable. OBJECTIVE To report erectile function and early oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping. DESIGN, SETTING, AND PARTICIPANTS In a prospective nonrandomised trial, we recruited 2545 men with prostate cancer from seven open (n=753) and seven robot-assisted (n=1792) Swedish centres (2008-2011). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Clinometrically-validated questionnaire-based patient-reported erectile function was collected before, 3 mo, 12 mo, and 24 mo after surgery. Surgeon-reported degree of neurovascular-bundle preservation, pathologist-reported positive surgical margin (PSM) rates, and 2-yr prostate-specific antigen-relapse rates were measured. RESULTS AND LIMITATIONS Among 1702 preoperatively potent men, we found enhanced erectile function recovery for low/intermediate-risk patients in the robot-assisted group at 3 mo. For patients with high-risk tumours, point estimates for erectile function recovery at 24 mo favoured the open surgery group. The degree of neurovascular bundle preservation and erectile function recovery were greater correlated for robot-assisted surgery. In pT2 tumours, 10% versus 17% PSM rates were observed for open and robot-assisted surgery, respectively; corresponding rates for pT3 tumours were 48% and 33%. These differences were associated with biochemical recurrence in pT3 but not pT2 disease. The study is limited by its nonrandomised design and relatively short follow-up. CONCLUSIONS Earlier recovery of erectile function in the robot-assisted surgery group in lower-risk patients is counterbalanced by lower PSM rates for open surgeons in organ-confined disease; thus, both open and robotic surgeons need to consider this trade-off when determining the plane of surgical dissection. Robot-assisted surgery also facilitates easier identification of nerve preservation planes during radical prostatectomy as well as wider dissection for pT3 cases. PATIENT SUMMARY For prostate cancer surgery, an open operation reduces erection problems in high-risk cancers but has higher relapse rates than robotic surgery. Relapse rates appear similar in low/intermediate-risk cancers and the robot appears better at preserving erections in these cases.

Abstract
OBJECTIVE To longitudinally describe practice of Complementary and Alternative Medicine (CAM) self-care strategies for nausea during radiotherapy. METHODS Two hundred patients daily registered nausea and practice of CAM self-care strategies, beside conventional antiemetic medications, for nausea during abdominal/pelvic irradiation (median five weeks) for gynecological (69%) colorectal (27%) or other tumors (4%). RESULTS During radiotherapy, 131 (66%) experienced nausea, and 50 (25%) practiced self-care for nausea at least once, for a mean (m) of 15.9days. The six of 50 patients who stayed free from nausea practiced self-care more frequent (m=25.8days) than the 44 patients experiencing nausea (m=14.5) (p=0.013). The CAM self-care strategies were: modifying eating (80% of all self-care practicing patients, 80% of the nauseous patients versus 83% of the patients free from nausea; ns) or drinking habits (38%, 41% vs 17%; ns), taking rests (18%, 20% vs 0%; ns), physical exercising (6%, 2% vs 33%; p=0.035), acupressure (4%, 5% vs 0%; ns) and self-induced vomiting (2%, 2% vs 0%; ns). CONCLUSION A fourth of patients undergoing emetogenic radiotherapy practiced CAM self-care for nausea, mostly by modifying eating or drinking habits. The CAM self-care practicing patients who did not become nauseous practiced self-care more frequent than the nauseous patients did. To make such self-care evidence based, we need studies evaluating its efficacy.
