Guest Editorial: are diabetes‐related wounds and amputations worse than cancer?

Certainly one of the most feared complications of diabetes is the lower extremity amputation 1. This fear is not unwarranted. Diabetes-related ulcer and amputation may be associated with surprisingly high 5-year mortality. Moulik et al.2 reported a 5-year mortality of 45%, 18% and 55% for neuropathic, neuroischaemic and ischaemic ulcers, respectively. As expected, mortality was higher in ischaemic ulcers than neuropathic ulcers. However, it is fairly evident based on these data that all types of diabetic foot ulcers are associated with high morbidity and mortality. Similarly, approximately half the persons receiving a diabetes-related amputation will not be alive in 5 years. Certainly, peripheral vascular disease may be implicated as a significant factor associated with shorter life span. Criqui reported the 10-year mortality in patients with peripheral arterial disease and found a substantially higher risk of mortality among patients with large vessel peripheral arterial disease – a factor that may be even more profound today than when it was reported in the early 1990s 3, 4. Faglia et al. related this high mortality with the absence of revascularisation, citing a 1.7-fold greater risk for death in ischaemic subjects who might have benefited from intervention 5. How do these data compare with other serious medical conditions, such as cancer? If one reviews Figure 1, one might conclude that persons with lower extremity complications of diabetes have 5-year mortality rates similar or worse than many common types of cancer 6-10. In fact, some high-risk subgroups such as persons with renal disease requiring distal bypass may have 5-year mortality rates approaching 95% 10. Five-year mortality (%). Perhaps now is the time to change our discussion with health-care administrators, policy makers and especially ourselves. The disease state that many of us treat routinely is, quite literally, killing our patients at a rate comparable to cancer. Addressing this issue aggressively may alter this and make a difference for millions of people worldwide.
