- Backround: We wanted to characterize conditional survival in prostate cancer (PC) in Sweden around and after 2005 when the vast increase in incidence due to the opportunistic testing for prostate specific antigen (PSA) culminated. We hypothesize that analyzing survival data during that time period may help interpret survival trends. We focus on stage-specific analysis using conditional survival in order to define the periods when deaths most commonly occurred. Methods: Data on PC patients were obtained from the Swedish cancer registry for analysis of 1-, 2.5- and 5-year relative survival and conditional relative survival between years 2004 and 2018. Tumor-node-metastatic stage classification at diagnosis was used to specify survival. Results: Small improvements were observed in stage- and age-related relative survival duriring the study period. Applying conditional relative survival showed that survival in stage T3 up to 2.5 years was better than survival between years 2.5 and 5. Survival in stage T4 was approximately equal in the first and the subsequent 2.5-year period. For M1, the first 2.5 year survival period was worse than the subsequent one. The proportion of high risk and M1 disease in old patients (80+ years) remained very high and their survival improved only modestly. Conclusions: The data indicate that M1 metastases kill more patients in the first 2.5 years than between years 2.5 and 5 after diagnosis; T4 deaths are equal in the two periods, and in T3 mortality in the first 2.5-year period is lower than between years 2.5 and 5 after diagnosis. Conditional survival could be applied to explore critical survival periods even past 5 years after diagnoses and to monitor success in novel diagnostic and treatment practices. Improvement of survival in elderly patients may require clinical input.

- PurposeTo investigate the short- and long-term risk of psychotropic medication use in parents who lose a child to cancer diagnosed in adolescence.MethodsThis is a Swedish nationwide register-based study including 184 bereaved mothers and 184 bereaved fathers of 184 children diagnosed with cancer in adolescence. Logistic regression analyses, adjusted for sociodemographic characteristics and history of mental health problems, were performed to estimate risk of a prescription of psychotropic medication (anxiolytics, hypnotics/sedatives, antidepressants) in cancer-bereaved parents from 1 year before to 5 years after the child's death, with a general population sample of non-bereaved parents (n = 3291) as referents.ResultsAt the year of the child's death, 28%–36% of mothers and 11%–20% of fathers had a prescription of anxiolytics, hypnotics/sedatives or antidepressants. The corresponding percentages for non-bereaved mothers and fathers were 7%–12% and 4%–7%, respectively. Compared to non-bereaved mothers, bereaved mothers showed higher odds of prescriptions from 1 year before up to four (anxiolytics) and 5 years (hypnotics/sedatives and antidepressants) after the child's death. Bereaved fathers showed higher odds than non-bereaved fathers of prescriptions from 1 year before up to the year of (anxiolytics and hypnotics/sedatives) and 1 year after (antidepressants) the child's death. No differences in odds between bereaved and non-bereaved fathers were found at 2 years after the child's death. Being unmarried, born outside Sweden, and having a history of mental health problems were associated with higher odds of prescribed medications.ConclusionsIndicative of mental health problems of clinical importance, cancer-bereaved parents had a higher prevalence of use of psychotropic medication. A decrease in medication use was evident with time, but still at 5 years after the child's death mothers displayed a higher use while fathers showed no difference to non-bereaved fathers after 2 years.

- BACKGROUND: Children experience a higher risk of psychiatric problems when their parents are diagnosed with cancer. However, the psychological effect among offspring who are born after parental cancer diagnosed in childhood or adolescence is unknown. We aimed to investigate the risk of psychiatric disorders in children of survivors with childhood or adolescent central nervous system (CNS) tumors.METHODS: By combining several nationwide Swedish registers, we identified all children who had at least one parent previously diagnosed with CNS tumor below the age of 20. Five children without parental CNS tumor were randomly selected for the matching. Cox proportional hazards model was used to calculate hazard ratios (HRs) with 95% confidence interval (CI).RESULTS: The incidence rate of psychiatric disorders was 8.46 per 1000 person-years in children of CNS tumor survivors, whereas the rate was 7.47 in the matched comparisons, yielding an adjusted HR of 1.10 (95% CI = 0.94, 1.28). Boys of survivors had a higher risk of psychiatric disorders (adjusted HR = 1.29, 95% CI = 1.04, 1.59). The risk of the specific types of psychiatric disorders in children of tumor survivors was comparable with that in the matched comparisons, except for mental retardation. Children of survivors experienced 2.36 times higher risk of mental retardation (95% CI = 1.21, 4.58), mainly of mild mental retardation (adjusted HR = 2.99, 95% CI = 1.40, 6.38).CONCLUSION: Children of survivors with CNS tumor in early life did not experience a significantly increased risk of overall psychiatric disorders, with the exception of an elevated risk of mental retardation that was mainly mild.

- Background: Patients with muscle-invasive bladder cancer (MIBC) constitute a heterogenous group in terms of patient and tumour characteristics (‘case-mix’) and prognosis. The aim of the current study was to investigate whether differences in survival could be used to separate MIBC patients into separate classes using a recently developed latent class regression method for survival analysis with competing risks.Methods: We selected all participants diagnosed with MIBC in the Bladder Cancer Data Base Sweden (BladderBase) and analysed inter-patient heterogeneity in risk of death from bladder cancer and other causes.Results: Using data from 9653 MIBC patients, we detected heterogeneity with six distinct latent classes in the studied population. The largest, and most frail class included 50% of the study population and was characterised by a somewhat larger proportion of women, higher age at diagnosis, more advanced disease and lower probability of curative treatment. Despite this, patients in this class treated with curative intent by radical cystectomy or radiotherapy had a lower association to risk of death. The second largest class included 23% and was substantially less frail as compared to the largest class. The third and fourth class included each around 9%–10%, whereas the fifth and sixth class included each 3%–4% of the population.Conclusions: Results from the current study are compatible with previous research and the method can be used to adjust comparisons in prognosis between MIBC populations for influential differences in the distribution of sub-classes.
