Earlier diagnosis and treatment of symptomatic bowel cancer: can it be achieved and how much will it improve survival?

AIM

To determine current delays in diagnosis and treatment of bowel cancer, when and why they occur, and what effect they have on survival.

METHOD

A detailed review of the literature based on the development of the GP referral guidelines in 2000.

RESULTS

There is no evidence of a reduction in the delay to diagnosis and treatment of bowel cancer over the last 60 years. There is no strong theoretical basis for a benefit from earlier diagnosis of symptomatic bowel cancer and this is consistent with observational studies.

CONCLUSION

Campaigns to earlier diagnose bowel cancer will not be successful unless new strategies are developed. There is substantial evidence that earlier diagnosis of symptomatic bowel cancer will not improve survival in the majority of patients. However as excessive delays still occur in some patients it is reasonable to continue to aim to diagnose and treat all bowel cancer within 6 months of the onset of symptoms with an overall median of 3-4 months.

The concept of prevention: a good idea gone astray?

Over time, the definition of prevention has expanded so that its meaning in the context of health services is now unclear. As risk factors are increasingly considered to be the equivalent of "diseases" for purposes of intervention, the concept of prevention has lost all practical meaning. This paper reviews the inconsistencies in its utility, and suggests principles that it should follow in the future: a population orientation with explicit consideration of attributable risk, the setting of priorities based on reduction in illness and avoidance of adverse effects, and the imperative to reduce inequities in health.

A fragment of the explanation': the use and abuse of words

This paper explores the normative basis of power in language, story, labels and evidence, and attempts to show how these dimensions of power are used systematically to simplify the reality of exprience, deny ignorance and exclude uncertainty. Through the resulting abuse of words, doctors may often constrain and limit their patients' stories, consigning many of them to stories of failure, and reducing their capacity to celebrate, or even recognise, achievement.

Joining together to combat poverty

The International Poverty and Health Network (IPHN) was created in December 1997 following a series of conferences organized by the World Health Organization, with the aim of integrating health into plans to eradicate poverty. Around 1.3 billion people live on less than US$1 per day. Of the 4.4 billion people in developing countries nearly 60% lack access to sanitation, 30% do not have clean water, 20% have no health care, and 20% do not have enough dietary energy and protein. Even among rich nations there are gross socioeconomic inequalities. Many children are robbed of their physical and mental potential through poverty. Expressed in constant 1963 US dollars, an average Croatian family needed the annual income of US$894 to meet the poverty line in 1960 and US$9,027 in 1995. Accordingly, 9-25% of Croatian households were below the poverty line between 1960 and 1995. The increase in the poverty rate after 1991 was compounded by the war that destroyed almost a third of industrial capacity and infrastructure. Dissipation of the communist economy and inadequate privatization have contributed to the increase in unemployment rate, corruption, and other social ills. IPHN invited Croatian Medical Journal to publish this editorial to help push the issue of poverty up political and medical agendas on a global level. We argue that a factor contributing to the failure of most large-scale programs against poverty to date is the excessive emphasis on material and infrastructure assistance at the expense of spiritual, moral, and intellectual development.
