Objective. Patients with infammatory bowel disease (IBD) are at increased risk from skin cancer. Aims include assessing IBD
patients’ risk factors and knowledge of skin cancer and current skin protection practices to identify gaps in patient education
regarding skin cancer prevention in IBD. Methods. IBD patients ≥ 18 years were recruited to complete an online survey. Results. 164
patients (mean age 43.5 years, 63% female) with IBD (67% Crohn’s disease, 31% ulcerative colitis, and 2% indeterminate colitis) were
included. 12% ( = 19) of patients had a personal history and 34% ( = 55) had a family history of skin cancer. Females scored better
on skin protection (16.94/32 versus 14.53/32, ≤ 0.03) and awareness (35.16/40 versus 32.98/40, ≤ 0.03). Patients over 40 years
old scored better on prevention (17.45/28 versus 15.35/28, = 0.03). Patients with skin cancer scored better on prevention (20.56/28
versus 15.75/28, ≤ 0.001) and skin protection (21.47/32 versus 15.33/32, ≤ 0.001). 61% of patients recognized the link between
skin cancer and IBD. Conclusions. Te majority of IBD patients are aware of the link between skin cancer and IBD; however, skin
protection practices are suboptimal. Tis emphasizes the role of healthcare professionals in providing further education for skin
cancer prevention in the IBD population.
1. Introduction
Skin cancer is the most common form of cancer in the United
States and causes signifcant morbidity and mortality [1].
Infammatory bowel disease (IBD) is a chronic autoimmune
condition that is associated with increased risk of develop-
ment of skin cancer. Proposed mechanisms predisposing IBD
patients to skin cancer include chronic infammation, cellular
damage, and underlying immune dysfunction leading to
altered tumor surveillance [2–4].
Use of immunosuppressants in IBD patients has been
shown to lead to a 4–7-fold increased risk of skin cancer
and approximately half of IBD patients are exposed to these
medications within 5 years of diagnosis [3]. Specifcally, the
use of biologic and immunomodulating agents increases
skin cancer risk [2–6]. Similarly, immunosuppression has
been shown to accelerate the development of skin cancer
in transplant patients; thus, routine skin exams are recom-
mended [3, 4]. According to the United States Preventive
Service Task Force, there is insufcient evidence to assess
the risk versus beneft for general skin cancer screening [7].
In addition, there is a lack of data to support that early
detection of skin cancer reduces morbidity and mortality [5].
However, patients with IBD have diferent risk factors for skin
cancer development compared to the general population.
Tus, these skin cancer screening recommendations may not
be applicable to IBD patients. Despite the lack of specifc
standardized guidelines for screening, there is general con-
sensus among gastroenterologists that IBD patients should
protect themselves from the sun and that annual skin cancer
surveillance should be considered, especially for patients on
biologic and immunomodulating agents [5, 8, 9].
Tus, it is important for IBD patients to be aware of their
risk of skin cancer and to adopt preventive strategies for
