Background: Non-persistence and non-compliance are common in women prescribed hormonal therapy for breast cancer, but little is known about their influence on recurrence.

Methods: A nested case-control study of associations between hormonal therapy non-persistence and non-compliance and the risk of early recurrence in women with stage I-III breast cancer was undertaken. Cases, defined as women with a breast cancer recurrence within 4 years of hormonal therapy initiation, were matched to controls (1 : 5) by tumour stage and age.

Background: Radical prostatectomy (RP) is a leading treatment option for localised prostate cancer. Although hospital in-patient stays accounts for much of the costs of treatment, little is known about population-level trends in length-of-stay (LOS). We investigated factors predicting hospital LOS and readmissions in men who had RP following prostate cancer.

Dancers are expected to maintain consistently high levels of performance capability and to perform on demand. To meet these expectations, they subject their bodies to long hours of intensive physical training. Such training regimens are often combined with tight rehearsal and performance schedules, which over time can lead to persistent fatigue, psychological distress, performance decrements, and injury.

Background: Geriatric oncology guidelines state that fit older men with prostate cancer should receive curative treatment. In a population-based study, we investigated associations between age and non-receipt of curative treatment in men with localised prostate cancer, and the effect of clinical variables on this in different age groups.

Methods: Clinically localised prostate cancers (T1-T2N0M0) diagnosed from 2002 to 2008 among men aged ≥ 40 years, with hospital in-patient episode(s) within 1 year post-diagnosis, were included (n=5456).

The criteria for allocation of medical cards to colorectal cancer patients < 70 were explored. All invasive colorectal cancers diagnosed during 2002-2006 (n = 4,762) were abstracted and linked to the PCRS master file to determine medical card status. Determinants of medical card possession before diagnosis were; age 65-69yr vs.

Background: A societal perspective in economic evaluation necessitates that all resources associated with a disease or intervention should be valued; however, informal care time costs are rarely considered.

Objective: We estimated time allocated to care by informal carers of colorectal cancer survivors; and investigated the impact of applying alternative valuation methods to this time.

Methods: Colorectal cancer cases (ICD10 C18-C20) diagnosed 6-30 months previously and identified from the National Cancer Registry Ireland were invited to provide details of informal carers.

Background: Fecal DNA (fDNA) testing is a noninvasive potential alternative to current colorectal cancer screening tests.

Objective: We conducted a systematic review and quality assessment of studies of cost-effectiveness of fDNA as a colorectal cancer screening tool (compared with no screening and other screening modalities), and identified key variables that impinged on cost-effectiveness.

Data Sources: We searched MEDLINE, Embase, and the Centre for Reviews and Dissemination for cost-effectiveness studies of fDNA-based screening, published in English by September 2011.

Guidelines that recommend spirometry to confirm airflow obstruction among patients with suspected COPD are not routinely followed. We conducted a qualitative study to identify attitudes and barriers of primary care physicians to performing spirometry for patients with possible COPD. We conducted four focus groups, each with three primary care physicians (PCPs) who practice in an urban, academic medical center.

Background: Organised colorectal cancer screening is likely to be cost-effective, but cost-effectiveness results alone may not help policy makers to make decisions about programme feasibility or service providers to plan programme delivery. For these purposes, estimates of the impact on the health services of actually introducing screening in the target population would be helpful. However, these types of analyses are rarely reported.
