State central cancer registries are often asked to respond to questions about the spatial distribution of cancer cases. Spatial analysis methods and technology are evolving rapidly, and can be a considerable challenge to registries that do not have staff with training in this area. The purpose of this article is to describe a general methodological approach that potentially might be a starting point for many cancer registry spatial analyses at the county level. ⋯ Mapping disease occurrence by time period is an effective way to explore spatio-temporal patterns. HGLM models and software are available to control for covariates and for unstructured and spatially structured variability that may confound spatial variability patterns.

Maps depicting the geographic variation in cancer incidence, mortality or treatment can be useful tools for developing cancer control and prevention programs, as well as for generating etiologic hypotheses. An important question with every cancer map is whether the geographic pattern seen is due to random fluctuations, as by pure chance there are always some areas with more cases than expected, or whether the map reflects true underlying geographic variation in screening, treatment practices, or etiologic risk factors. ⋯ When publishing cancer maps we recommend evaluating the spatial patterns observed using Tango's MEET, a global clustering test, and the spatial scan statistic, a cluster detection test.

Current healthcare evidence relies on relatively narrow efficacy data to make decisions about program impact. This paper illustrates the application of impact indices derived from the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework that takes a broader perspective and includes issues important to decision makers, such as reach, adoption, and cost. ⋯ Greater use of indices focused on public health and external validity criteria could help identify programs most likely to have a meaningful impact on population health and to fit local settings and priorities.

Nondaily smokers are a growing subpopulation of smokers. Current cessation guidelines were developed for daily smokers, and how clinicians might help nondaily smokers is not clear. ⋯ While daily smokers may seem a higher cessation priority, nondaily smokers may be more likely to quit with brief interventions. Cessation messages should address health risks of any smoking, ethnic differences, smoke-free messages, and situational triggers.

This discussion examines the use of litigation as a strategy to protect the public health. The history of tobacco litigation provides a model to evaluate potential litigation strategies against other industries that pose a threat to public health, particularly the food industry. This paper demonstrates that although legislation would be a preferable solution, lessons from the tobacco wars suggest that effective national legislation is unlikely at the present time. ⋯ Likewise, state lawsuits under consumer protection acts may be a distinct type of litigation that permits cases to focus on deceptive advertisements while avoiding complicated causation issues. Such lawsuits have the potential to be a useful tool to fight obesity and enlist the efforts of the food industry in resisting the epidemic. Understanding the lessons of tobacco can save public health advocates much time and many resources and thus allow tobacco litigation to benefit public health in new ways.
