Background: Previous studies have suggested an increased risk of cancer among patients with scleroderma. Objective: To study a population based cohort of patients with scleroderma in South Australia. Methods: Subjects with scleroderma were identified from the South Australian Scleroderma Registry established in 1993. All subjects on the scleroderma registry were linked to the South Australian Cancer Registry to identify all cases of cancer until 31 December 2000. Standardised incidence ratios (SIRs) for cancer for subjects with scleroderma were determined using the age- and sex-specific rates for South Australia. Results: In 441 patients with scleroderma, 90 cases of cancer were identified, 47 of which developed after inclusion on the scleroderma registry. The SIRs for all cancers among these patients were significantly increased (SIR=1.99; 95% confidence interval (95% CI) 1.46 to 2.65) compared with the cancer incidence rates for South Australia. The SIRs for lung cancer (SIR=5.9; 95% CI 3.05 to 10.31) were also significantly increased. The SIRs for all cancers among the subgroups with diffuse scleroderma (SIR=2.73; 95% CI 1.31 to 5.02) and limited scleroderma (SIR=1.85; 95% CI 1.23 to 2.68) were significantly increased. Conclusions: This population based cohort study provides evidence that scleroderma is associated with cancer, and in particular, lung cancer. In addition, both diffuse and limited forms of scleroderma are associated with a similarly increased risk of cancer.

In a population survey, 2652 respondents aged 15+years reported their preferred place of death, if dying of ‘a terminal illness such as cancer or emphysema’, to be home (70%), a hospital (19%), hospice (10%), or nursing home (< 1%). The majority of respondents in all socio-demographic categories reported a preference for dying at home, with the greatest majorities occurring in younger age groups. After weighting to the age-sex distribution of all South Australian cancer deaths, 58% in our survey declared a preference to die at home, which is much higher than the 14% of cancer deaths that actually occurred at home in South Australia in 2000-2002. Multivariable analyses indicate that predictors of preferred home death include younger age, male, born in the UK/Ireland or Italy/Greece, better physical health, poorer mental health, and fewer concerns about dying at home. Predictors of preference for death in a hospice rather than hospital include older age, female, single, metropolitan residence, having higher educational and income levels, paid employment, awareness of advanced directives, and interpreting ‘dying with dignity’ as death without pain or suffering. Investigating the differences between preferred and actual places of death may assist service providers to meet end-of-life wishes.

BACKGROUND: Previous reports have described differences in biology and outcome for colorectal cancer based on whether the primary is right or left sided. Further division by right, left, and rectum or even exact primary site has also been explored. Possible differences in response to biological agents have also been reported based on side of primary lesion.METHODS: We explored the South Australian registry for metastatic colorectal cancer to assess if there were any differences in patient characteristics, prognostic markers, and treatment received and outcomes based on whether the primary was right or left sided. We also explored if differences exist based on left colon and rectum and by exact primary site.RESULTS: Two thousand nine hundred seventy‐two patients were analyzed. Thirty‐five percent had a right‐sided primary. The median overall survival for the entire group right versus left was 9.6 versus 20.3 months (P < .001). Multivariate analysis confirmed side of primary as an independent prognostic factor. For the group that had active therapy, defined as chemotherapy (± metastasis resection), median overall survival was right, 18.2 months; and left, 29.4 months (P < .001). Importantly, we found no suggestion of major differences if left side was divided by left colon and rectum, and trends by individual site still supported a left and right division.CONCLUSIONS: Patients with a right‐sided primary have more negative prognostic factors and indeed have inferior outcomes compared with those with a left‐sided primary. Our data with further breakdown by exact site still favor a simple left‐versus‐right division moving forward for metastatic colorectal cancer. Cancer 2015;121:830–835. © 2014 American Cancer Society.
