Perceptions of Risk of Developing Skin Cancer for Diverse Audiences: Enhancing Relevance of Sun Protection to Reduce the Risk

Cutaneous Squamous Cell Carcinoma

Cutaneous squamous cell carcinoma represents 20% of all skin cancers, resulting in 1 million cases in the United States each year. The lifetime risk of developing squamous cell carcinoma continues to increase annually and will likely continue to increase because of the aging population. Most cutaneous squamous cell carcinoma are treated locally, with a subset leading to recurrence, metastasis, and death. This review of cutaneous squamous cell carcinoma covers incidence, recurrence rates, mortality rates, risk factors, staging systems, treatment, prevention, and monitoring.

Behavioural and pharmaceutical interventions for the prevention of skin cancers in solid organ transplant recipients: a systematic review of randomised controlled trials

OBJECTIVES

Solid organ transplant recipients are at increased risk of skin cancer, affecting more than 50% of recipients. We aimed to determine the effectiveness of interventions for behavioural change for sun protection or skin cancer prevention in solid organ transplant recipients.

DESIGN

Systematic review.

DATA SOURCES

We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL) and CINAHL from inception to November 2019.

ELIGIBILITY CRITERIA

We included randomised controlled trials that evaluated the effect of behavioural or pharmaceutical interventions on behavioural change or skin cancer prevention in solid organ transplant recipients.

DATA EXTRACTION AND SYNTHESIS

Risks of bias and evidence certainty were assessed using Cochrane and the Grading of Recommendations Assessment Development and Evaluation framework.

RESULTS

Twenty trials (n=2295 participants) were included. It is uncertain whether behavioural interventions improve sun protection behaviour (n=3, n=414, standardised mean difference (SMD) 0.89, 95% CI -0.84 to 2.62, I²=98%) and knowledge (n=4, n=489, SMD 0.50, 95% CI 0.12 to 0.87, I²⁼ 76%) as the quality of evidence is very low. We are uncertain of the effects of mammalian target of rapamaycin inhibitors on the incidence of non-melanocytic skin cancer (n=5, n=1080, relative risk 0.46, 95% CI 0.28 to 0.75, I^{2 =}72%) as the quality of evidence is very low.

CONCLUSIONS

Behavioural and pharmaceutical preventive interventions may improve sun protective behaviour and knowledge, and reduce the incidence of non-melanocytic skin cancer, but the overall quality of the evidence is very low and insufficient to guide decision-making and clinical practice.

Skin Cancer Awareness and Sun Protection Behavior Before and Following Treatment Among Skin Cancer-Treated Patients

There is little known about illness perception in patients with skin tumors. We conducted this study to investigate Iranian patients' understanding of skin tumors, and to evaluate their sun-protective behavior changes after treatment of skin cancer. Patients with a skin biopsy of basal cell carcinoma were asked to complete questionnaires. A total of 110 patients were enrolled in the study. Patients were mostly referred to our tumor clinic from rural areas. At the skin cancer perception investigation, 63% of patients did not consider their disease as a long-lasting situation. Besides, 45.4% of patients consider their illness as a serious condition which significantly affecting their lives. Our patients had a strong belief in treatment control (81%) and 81% of them also described worries about their skin cancer. The leading causes of skin cancer as assumed by patients were: history of skin cancer (37.4%), poor medical care in the past (36.4%), extreme sun exposure (31.5%), and lack of sun protection (27.5%). In regard to sun-protective behavior after treatment of skin cancer, 55.4% of patients showed no changes or even negative change in their sun-protective behavior, But 44.5% of the patients changed their sun-protective behavior in a positive way which was statically significant (P ≤ 0.001). Our study demonstrates how our patients with skin cancer perceive their disease and we need to educate our patients, considering diseases' aspects, causes and symptoms. This is of great value as dermatologists should be aware of patients' perceptions of their disease in order to improve patients' knowledge through educating more about different aspects of disease.

A qualitative systematic review of the efficacy of sun protection education in organ transplant recipients

BACKGROUND

Transplant recipients are at increased risk of developing skin cancer as a result of chronic immunosuppression. Educating patients on sun protection has been routine posttransplantation, but to our knowledge, no systematic review has yet analyzed the efficacy of such education measures in this high-risk population.

OBJECTIVE

We sought to examine the efficacy of educating transplant recipients on skin cancer and sun protection.

METHODS

A literature search of interventional patient education studies published between January 1995 and March 2016 was performed in PubMed, CINAHL, Cochrane, and EMBASE databases.

RESULTS

Data from 7 studies meeting inclusion criteria were analyzed. No study attempted to examine the direct effect of sun protection education on skin cancer incidence in transplant recipients. Two randomized controlled trials showed that educational intervention can improve sun-protective behavior and decrease skin pigmentation or skin damage in sun-exposed areas. Three other randomized controlled trials compared the efficacy of 2 different forms of patient education at changing sun-protective behavior, but did not examine patient-oriented outcomes.

LIMITATIONS

A lack of high-quality randomized controlled trials with patient-oriented evidence and a dependence on self-reported data are limitations.

CONCLUSION

Sun protection education can be effective at altering patient behavior in transplant recipients, but its effect on posttransplantation skin cancer incidence remains to be elucidated.

A Randomized Controlled Trial of a Mobile Medical App for Kidney Transplant Recipients: Effect on Use of Sun Protection

BACKGROUND

Perception of skin cancer risk, belief that sun protection prevents skin cancer, and having sun protection choices enhance sun protection behaviors by kidney transplant recipients, who are at greater risk of developing skin cancer than the general population.

METHODS

A randomized controlled trial used stratified recruitment of non-Hispanic White, non-Hispanic Black, and Hispanic/Latino kidney transplant recipients, who received a transplant 2-24 months prior to the study. The same culturally sensitive SunProtect™ program was delivered to all recipients with tablet personal computers in two urban ambulatory offices. Text messages reminders were provided at two week intervals. Self-reported surveys and skin pigmentation measured prior to the intervention and six weeks later were analyzed.

RESULTS

Among 552 eligible participants, 170 participated (62 non-Hispanic Whites, 60Blacks, and 48 Hispanics). Among participants receiving the intervention with skin that burns after sun exposure and becomes tan or becomes irritated and gets darker, there was a statistically significant increase in self-reported knowledge, recognition of personal skin cancer risk, confidence in sun protection preventing skin cancer, and sun protection behaviors in participants compared to those receiving usual education (p<0.05). At the six week follow-up, participants in the intervention group with skin that burns or becomes irritated, had significantly less darkening of the sun-exposed forearm than control participants (p<0.05).

CONCLUSIONS

Providing sun protection education with SunProtect™ in the springwith reminders during the summer facilitated adoption of sun protection behaviors among kidney transplant recipients with skin that burns or becomes irritated.
