Accessing cancer services in North West England: the Chinese population.

Relatively few Chinese patients access tertiary cancer services in North West England. We investigated the reasons behind this using a culturally sensitive questionnaire. The questionnaire, completed by 214 Chinese people in English, Cantonese or Mandarin, evaluated the Chinese population's access and satisfaction with primary care, understanding of cancer and awareness of local cancer services. Ninety-five per cent of respondents were registered with a general practitioner (GP) and 75% had accessed primary care in the last year. Satisfaction with GP consultations was high but a third of respondents reported a lack of confidence in local National Health Service (NHS) services. Only 57% of eligible women had attended cervical screening programmes. The overall understanding of the causes and treatment of cancer and cancer services in the North West was poor. Despite registration with primary healthcare, the Chinese population under-utilise cancer prevention programmes and tertiary cancer services because of a lack of awareness and understanding of cancer services in the North West. A significant proportion of the population is dissatisfied with the perceived slow service and lack confidence in services, with 41% considering using healthcare abroad. These data highlight the critical need to engage with, educate and support the Chinese population if they are to access NHS cancer services.

Assessment of diurnal changes and confounding factors that affect circulating cell death biomarker levels: a short communication.

There is increasing use of circulating cell death biomarkers in patients and clinical trials. Knowledge of the potential noise and confounders in assays are vital for biomarker interpretation. The daily and diurnal variability and effect of menstruation and exercise on nucleosomal DNA (nDNA), total cytokeratin 18 (tK18) and apoptotic specific cytokeratin 18 (cK18) were assessed in 3 cohorts of healthy volunteers; 12 pre-menopausal women to establish the effect of menstruation, 12 men to perform exercise and 12 post-menopausal women. All 36 subjects were evaluated to establish daily and diurnal variability. Estimates of variability were derived in a linear mixed effects model and presented as the back transformed coefficient of variation (%CV). Minimal variation was seen in cK18 (11%CV) and tK18 (11%CV) but higher variability was seen in nDNA (85%CV). K18 results appeared stable throughout the day but a possible peak in nDNA was seen at 15:00. Menstruation had minimal effects but exercise led to immediate short-lived elevations in cell death biomarkers. There is no evidence of significant daily variability in K18 assays. We recommend subjects should not exercise for 6h before blood sampling.
