Comparative StudyCancer survival in Indigenous and non-Indigenous Australian children: what is the difference?
This study assessed variation in childhood cancer survival by Indigenous status in Australia, and explored the effect of place of residence and socio-economic disadvantage on survival. ⋯ Differences in place of residence, socio-economic disadvantage, and cancer diagnostic group only partially explain the survival disadvantage of Indigenous children. Other reasons underlying the disparities in childhood cancer outcomes by Indigenous status are yet to be determined, but may involve factors such as differences in treatment.

Fruit and vegetable intake and the risk of colorectal cancer: results from the Shanghai Men's Health Study.
The observed associations of fruit and vegetable consumption with the risk of colorectal cancer have been inconsistent. Therefore, we aimed to evaluate the association of fruit and vegetable consumption with the risk of colorectal cancer among Chinese men. ⋯ Fruit intake was generally inversely associated with the risk of colorectal cancer, whereas vegetable consumption was largely unrelated to risk among middle-aged and older Chinese men.

The impact of a two- versus three-yearly cervical screening interval recommendation on cervical cancer incidence and mortality: an analysis of trends in Australia, New Zealand, and England.
To assess the impact of cervical screening interval recommendations on cervical cancer incidence and mortality during periods of organized and opportunistic screening in Australia (2-yearly screening interval for organized screening), New Zealand (3 yearly interval for organized screening), and England (3/5 yearly interval for organized screening). ⋯ In the era of opportunistic screening, some reductions were observed in cervical cancer mortality rates, but these were relatively modest and seen inconsistently between countries. After the introduction of organized cervical screening, cervical cancer mortality rates fell by a similar amount (~40% or more) in all countries, and incidence fell by more than a third in Australia and New Zealand and by approximately one-fifth in England. Although several factors are likely to have influenced these observed reductions in cervical cancer rates, these findings do not support the more frequent 2-yearly cervical screening interval recommendation in Australia.

Impact of hormone replacement therapy use on mammographic screening outcomes.
This study aims to measure the impact of HRT use at the time of screening on rates of screen-detected invasive breast cancer (IBC) and ductal carcinoma in situ (DCIS), interval cancers and investigative procedures, within a well-established population-based mammography screening program. ⋯ Increased risks of recall, biopsy rates, screen-detected, and interval cancers among HRT users have important implications for population-based breast cancer screening programs. Our findings support the concept that HRT use may increase the growth of preexisting cancers. Lack of effect on DCIS could imply different etiology or time frames for DCIS and IBC development or increased transition from preinvasive to invasive disease due to HRT use.

Clinical trial discussion, referral, and recruitment: physician, patient, and system factors.
Patient participation in cancer clinical trials is imperative to the advancement of medical science. Physicians play an important role in recruitment by discussing clinical trials with their cancer patients. Patient-physician discussion is influenced by many factors relating to the physician, the patient, and the healthcare system. ⋯ Multilevel interventions may be successful at increasing participation of women in clinical trials.
