- Background: Symptoms of terminal cancer have previously been reported as under-treated. The aim of this study was to assess the use of palliative medications before death from prostate cancer. Methods: This Swedish register study included men who died from 2009 to 2012 with prostate cancer as the underlying cause of death. We assessed the proportion who collected a prescription of androgen deprivation therapy, non-steroidal anti-inflammatory drugs, paracetamol, opioids, glucocorticoids, antidepressants, anxiolytics and sedative-hypnotics and the differences in treatment related to age, time since diagnosis, educational level, close relatives and comorbidities. Data were collected from 3 years before death from prostate cancer. Results: We included 8326 men. The proportion who received opioids increased from 30% to 72% during the last year of life, and 67% received a strong opioid at the time of death. Antidepressants increased from 13% to 22%, anxiolytics from 9% to 27% and sedative-hypnotics from 21% to 33%. Men without close relatives and older men had lower probability to receive opioids (odds ratio [OR]: 0.56, 95% confidence interval [CI]: 0.47-0.66 for > 85 years versus < 70 years) and (OR 0.78, 95% CI: 0.66-0.92 for unmarried without children versus married with children). Conclusion: Our results represent robust epidemiological data from Sweden for comparison of palliative care quality between countries. The findings indicate that men without close relatives and older men are disadvantaged with respect to the treatment of cancer pain and need closer attention from health care providers and highlight the importance to identify psychological distress in terminal prostate cancer.

- INTRODUCTION: Predictors for site of distant metastasis and impact on survival in breast cancer are incompletely understood.METHODS: Clinico-pathological risk factors for site of distant metastasis and survival were analysed in patients with invasive breast cancer treated between 1986 and 2006.RESULTS: Of 3553 patients, with median follow-up 6.32years, 825 (23%) developed distant metastasis. The site of metastasis was bone in 196/825 (24%), viscera in 540/825 (65%) and unknown in 89 (11%). Larger primary invasive tumour size, higher tumour grade and axillary nodal positivity increased risk of metastasis to all sites. Lobular carcinoma was more likely to first metastasise to bone compared to invasive ductal carcinoma (NST). Oestrogen receptor (ER) negative, progesterone receptor (PgR) negative and/or Human epidermal growth factor (HER2) positive tumours were more likely to metastasise to viscera. A striking relationship between increasing age at diagnosis and a reduction in risk of distant metastasis to bone and viscera was observed. Median time to death from onset of metastatic disease was 1.52 (Interquartile range (IQR) 0.7-2.9)years for patients with bone metastasis and 0.7 (IQR 0.2-1.5)years for visceral metastasis. On multivariate analysis, despite the decrease in risk of distant metastasis with increasing age, there was an elevated hazard for death in patients >50years at diagnosis of metastasis if they developed bone metastasis, with a similar trend observed in the >70years age group if they developed visceral metastasis.CONCLUSION: These findings indicate that there are biological mechanisms underlying the impact of age on the development of distant metastasis and subsequent death. This may have important implications in the treatment of breast cancer.

- AIM: The primary aims were to study risk factors for an ipsilateral breast event (IBE) after sector resection for ductal carcinoma in situ of the breast (DCIS) in a trial comparing adjuvant radiotherapy to no therapy and to assess predictive factors for response to radiotherapy. Secondary aims were to analyse reproducibility of the histopathological evaluation and to estimate correctness of diagnosis in the trial. SETTING: A randomised trial in Sweden (the SweDCIS trial), including 1046 women with a median of 5.2 years of follow-up in a population, offered routine mammographic screening. METHODS: A case-cohort design with a total of 161 cases of IBE (42 of those being members of the subcohort) and 284 sampled for the sub-cohort. Ninety five percent of the participants' slides could be retrieved and were re-evaluated by three experienced pathologists. RESULTS: Low nuclear grade (NG 1-2) and absence of necrosis halves the risk of IBE in both irradiated and non-irradiated patients. Lesion size, margins of excision and age at diagnosis did not modify these associations. The presence of necrosis modified the effect of radiotherapy: relative risk was 0.40 with necrosis present and 0.07 with necrosis absent (p-value for interaction 0.068). In all subsets of prognostic factors, radiotherapy conferred a substantial benefit. The risk factors for in situ and invasive IBE were similar. The agreement between pathologists was moderate (kappa=0.486). Correctness of diagnosis in the subcohort of SweDCIS was 84.8%. CONCLUSION: Although nuclear grade and necrosis carry prognostic information, we could not define a group with very low risk after sector resection alone. Radiotherapy has a protective effect in all substrata of risk factors studied. The interaction between the presence of necrosis and radiotherapy is a clinically and biologically relevant research area.
