Screening for pancreatic cancer (PC) in high-risk groups aimed to detect early cancers is currently done only in the research setting, and data on psychological outcomes of screening in these populations is scarce. To determine the psychological impact of a national Australian pancreatic screening program, a prospective study was conducted using validated psychological measures: impact of events scale (IES), psychological consequences questionnaire (PCQ) and the cancer worry scale. Measures were administered at baseline, 1-month and at 1-year post-enrolment and correlations with abnormal endoscopic ultrasound (EUS) results were calculated. Over a 6-year period, 102 participants were recruited to the screening program. Thirty-nine patients (38.2%) had an abnormal endoscopic ultrasound, and two patients (2.0%) were diagnosed with PC and two with other malignancies. Those with a personal history of cancer or a positive BRCA2 mutation demonstrated significantly increased worry about developing other types of cancer at baseline (p < 0.01). Irrespective of EUS result, there was a significant decrease of total IES score at 1 year (Z = - 2.0, p = 0.041). In patients with abnormal EUS results, there was a decrease in the total IES score at 1 year (Z = - 2.5, p = 0.011). In participants deemed to be most distressed at baseline based on their negative PCQ score, there was a significant decrease of the total PCQ (Z = - 3.2, p = 0.001), emotional (Z = - 3.0, p = 0.001), social (Z = 3.0, p = 0.001) and physical (Z = - 2.8, p = 0.002) subscale at 1-year post-intervention. This study provides evidence of the long-term psychological benefits of PC screening in high-risk patients. There was no negative impact of screening in the short-term and the positive benefits appeared at 1-year post-intervention irrespective of screening result.

Objective: To estimate the prevalence of Huntington disease (HD) in New South Wales on Australian Census Day (6 August) 1996., Design: Survey of records of the Huntington Disease Service and major hospitals, and of neurologists, psychiatrists, clinical geneticists and genetic counsellors., Subjects and Setting: All patients in NSW who, on Census Day 1996, either had a definite diagnosis of HD (motor signs of chorea or ataxia and family history of HD or positive DNA test result) or would have had signs and later received a definite diagnosis (assessed 1 April 1997 to 1 July 1999)., Main Outcome Measures: Prevalence (HD patients per 100,000 population); patient characteristics; year and basis of diagnosis., Results: 380 patients with definite HD were identified, giving a prevalence of HD in NSW in 1996 of 6.29 per 100,000 population (95% CI, 5.68-6.96). A third of HD patients were aged 60 years or older. Diagnosis was confirmed by DNA testing for 171 patients (45%), including 30 (8%) with no recorded family history. Average numbers of new diagnoses per year were 11.8 (1984-1988), 21.8 (1989-1993) and 28.6 (1994-1998). Estimated number of people with a 50% risk of inheriting the HD mutation was 25.2 per 100,000 population. Estimated incidence of HD in 1996 was 0.65 per 100,000 population., Conclusions: Prevalence of HD in NSW is similar to estimated prevalence in other Australian and Western populations. Increasing numbers of cases are being diagnosed, and the 18 chronic care beds currently designated for HD patients in NSW are unlikely to be sufficient.
