Article
Aims: Among colorectal cancer (CRC) patients, preexisting diabetes is suggested to influence poor prognosis, but the impact on adjuvant chemotherapy implementation is largely unknown. We aimed to compare the implementation rate of adjuvant chemotherapy between CRC patients with and without preexisting diabetes in a retrospective cohort study. Met...
Article
In Japan, risk behaviors for cancer remain inadequately controlled, often due to a lack of necessary information and support to guide consumers in cancer control decisions. The use of strategic health communication efforts based on social marketing has substantial potential to provide groups of consumers who are underinformed or misinformed with re...
