Impact of Skin Cancer Awareness on Prophylactic Behavior Among Renal Transplant Recipients

Factors Affecting Knowledge Levels and Protective Behaviors to Prevent the Development of Skin Cancer in Organ Transplant Recipients as a High-Risk Group

OBJECTIVES

Organ transplantrecipients are at high risk of skin cancer due to immunosuppressant therapy. This study investigated the factors affecting organ transplant recipients' knowledge and protective behaviors to prevent the development of skin cancer.

MATERIALS AND METHODS

This was a cross-sectional descriptive study of kidney (n = 82) and liver (n = 31) transplant recipients seen at our hospitals in Turkey from June 2019 to February 2020. A sociodemographic and clinical characteristics form, the Skin Cancer and Sun Knowledge scale, the Sun Protection Behavior questionnaire, and the General Self-Efficacy scale were used to collect data.

RESULTS

The mean age of organ transplant recipients was 46.63 ± 13.24 years. Self-efficacy and awareness that transplant increases the risk of skin cancer are 2 characteristics that affected the participants' knowledge level. The type of graft (kidney) affected participants' behavior in avoiding outdoor exposure between the hours of 10 am and 4 pm. Green/blue eye color and self-efficacy affected the participants' hatwearing behavior. These details showed that, as the patients' sensitivity and self-efficacy increased, their levels of knowledge and sun protection behaviors were positively affected.

CONCLUSIONS

The knowledge level of patients was affected by (1) awareness that transplant is associated with an increased risk of skin cancer and (2) high levels of self-efficacy. We observed that (1) organ transplant recipients with high self-efficacy and kidney transplant recipients were more likely to avoid outdoor exposure between 10 am and 4 pm and that (2) organ transplant recipients with green/blue eyes and high levels of selfefficacy were more likely to wear a hat when outdoors. Organ transplant teams should provide education and counseling about skin cancer and sun protection in the follow-up care of transplant recipients.

Patterns of photoprotective behavior, cumulative sun-exposure and skin cancer risk among solid organ transplant recipients: a dermatology transplant clinic experience

BACKGROUND

The risk for keratinocyte cancer is dramatically increased in solid organ transplant recipients (OTR) with a first post-transplant keratinocyte cancer conferring a high risk for subsequent keratinocyte cancer arising with accelerated dynamics. Despite cumulative ultraviolet radiation (UVR) being the primary responsible environmental carcinogen reduced compliance with photoprotective measures among OTR has been reported. Risk assessment tools could help guide clinical decision-making and targeted prevention strategies for patients at particularly high risk for post-transplant keratinocyte cancer.

OBJECTIVES

To evaluate cumulative sun exposure by means of an assigned total sun burden (TSB) score, sunscreen use and associated risk factors for keratinocyte cancer in the post-transplantation phase of OTR.

METHODS

A retrospective single-center cohort study analyzing medical records and standardized questionnaires of 290 OTR cared for at a German dermatology transplant clinic.

RESULTS

Significantly lower TSB scores were noted in OTR not developing a first keratinocyte cancer compared to OTR developing keratinocyte cancer during their follow-up period ( P  = 0.005). Regression analysis assigned a significantly higher risk for the development of first keratinocyte cancer to OTR with TSB scores >10. In total 70.7% of OTR with a history of ≥1 keratinocyte cancer reported intermittent sunscreen use, while daily sunscreen use was overall associated with female gender (21.3%) and age >30 years (17.6%).

CONCLUSIONS

The risk of OTR for developing keratinocyte cancer is reflected by their UV-exposure patterns, which may be assessed by the TSB-score, a scored risk assessment tool. Complementing clinical data, the TSB score may help clinicians to identify OTR at particularly high risk for keratinocyte cancer and to endorse intensified prevention strategies and dermato-oncologic care.

Comparison of Patient and Provider Practices between Bone Marrow and Solid Organ Transplantation Programs for Patient Education on Increased Risk of Skin Cancer

Patients receiving immunosuppressive therapy following transplantation are at risk for skin cancer owing to dampened tumor surveillance. As long-term immunotherapy is necessary to prevent graft rejection, transplantation providers and recipients are expected to perform regular surveillance for the development of suspicious lesions, and recipients are encouraged to practice preventative sun safe behaviors. No consensus exists regarding the timing of full body skin exams, and despite the well-established risk, patient education is not always prioritized. We investigated whether differences exist between bone marrow transplant (BMT) and organ transplant (OT) recipients and their providers regarding prevention and screening. We distributed surveys to adult and pediatric BMT and OT recipients, as well as their providers, at a single academic institution. Results were evaluated using the chi-square test. The survey results show that most BMT recipients (69%) and OT recipients (77%) were aware of their increased risk for skin cancer, but despite this knowledge, only 13% of patients overall reported using sunscreen, 29% reported reapplying sunscreen, and 48% reported wearing sun protective clothing. Most OT recipients (63%) reported never having a total body skin exam, whereas only 34% BMT recipients reported having a total body skin exam every 6 months (P = .006). BMT providers recommended a total body skin exam every 6 or 12 months (44.4% each), and OT providers recommended a total body skin exam every 12 months (58.3%). Only 11.1% of BMT providers and 8.3% of OT providers reported performing a total body skin exam at each visit. Despite results indicating widespread patient knowledge of skin cancer risk, most patients do not practice adequate prevention. Inclusion of a transplantation dermatologist in the care team or use of risk stratification tools by providers may help streamline timely referrals to Dermatology.

An integrated skin cancer education program in renal transplant recipients and patients with glomerular disease

Sun-protective strategies focusing on skin cancer awareness are needed in immunosuppressed patients at risk of skin cancers. The study aims to determine the effect of an integrated skin cancer education program on skin cancer awareness and sun-protective behaviours in renal transplant recipients (RTRs) and patients with glomerular disease (GD) treated with long-term immunosuppressants. A pilot prospective cohort study in Central Queensland, Australia was undertaken among adult RTRs and patients with GD, who completed survey questionaries on skin cancer and sun-health knowledge (SCSK), sun-protection practices and skin examination pre- and post-education. Fifty patients (25 RTRs, 25 patients with GD) participated in the study. All of them completed questionnaires at pre-, 3-month post-education and 92%(n = 46) at 6-month post-education. There was a significant increase in SCSK scores from baseline at 3-months (p < 0.001) and 6-months post-intervention (p < 0.01). Improved knowledge was retained for 6 months after education. There were changes in 2 of 8 photoprotective behaviours at 6 months. Interventional education enhanced regular self-skin examination rate (p < 0.001) as well as the frequency of full skin checks by general practitioners (GPs) (p < 0.001). Overall, RTRs had better compliance with sun-protective methods and higher skin examination rates by themselves and/ or GPs before and after the intervention of education compared to patients with GD. To conclude, an integrated skin cancer education program improved knowledge of skin cancer and skin health as well as the frequency of self-skin examination and formal skin assessments. However, improvement in patient compliance did not extend to other sun-protective practices.

Comparison of skin cancer awareness and sun protection behaviours between renal transplant recipients and patients with glomerular disease treated with immunosuppressants

BACKGROUND

There is no previous study that compare skin cancer awareness and photoprotective behaviours between renal transplant recipients (RTR) and patients with glomerular disease (GD).

OBJECTIVES/METHODS

Sixty-one RTR and 51 patients with GD were given a self-reported questionnaire to evaluate skin cancer awareness and photoprotective behaviours in this cross-sectional study. The former group received a formal education on skin cancer and the latter an informal session prior to immunosuppressant use.

RESULTS

Ninety-three percent (n = 57) of RTRs and 88% (n = 45) of patients with GD responded to the survey. Majority of participants from both groups were aware that ultraviolet radiation could play a role in the occurrence of skin cancers and the awareness increased in participants with higher education (odds ratio [OR] = 1.50, 95% confidence interval [CI] = 1.15-1.95, P = .003). Ninety-eight percent vs 71% were aware that immunosuppressants can increase the risk of developing cancer (P < .001) and higher awareness was noted in younger participants (OR = 0.92, 95% CI = 0.87-0.97, P = .003). Suboptimal photoprotective behaviours (sun avoidance, sunscreen usage and sun-protective clothing) were noted in both cohorts and slightly lower sun protection rates were reported in RTR when compared with patients having GD. The level of sun protective measures in RTR based on high, moderate and minimal use of photoprotective measures were 21%, 46% and 33%, respectively. In terms of patients with GD, the latter practices were 13%, 50% and 37%, respectively (P = .560). Higher educational status was significantly associated with better sunscreen usage in RTR (P = .017) whereas this finding was not observed in patients with GD.

CONCLUSION

Patients with GD and RTR should have formal education on the risks of skin cancers before starting immunosuppressants. Follow-up education and surveillance is required to improve skin protective practices in these patients.

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.

Common Questions and Misconceptions in the Management of Renal Transplant Patients: A Guide for Health Care Providers in the Posttransplant Setting

Once renal transplant recipients are stabilized and require less frequent follow-up with their transplant team, health care providers outside of the transplant setting play an integral role in patients' ongoing medical care. Given renal transplant recipients' inherent complexity, these health care providers often seek consult regarding decisions that may affect transplant-related medications or outcomes. In this review, we discuss answers to 10 of the questions commonly posed to our renal transplant team by other health care providers.

Skin Cancer Risk Awareness and Sun-Protective Behavior Among Solid-Organ Transplant Recipients

OBJECTIVES

Solid-organ transplant recipients are at an increased risk of developing skin cancer; this risk is due to long-term graft-preserving immunosuppressive therapy, and excessive sun exposure is a major contributing factor to this process. The aim of this study was to evaluate the skin cancer awareness and sun-protective behavior of solid-organ transplant recipients.

MATERIALS AND METHODS

In all, 70 consecutive solid-organ transplant recipients were evaluated regarding knowledge of their increased skin cancer risk and regarding the influence of this knowledge on their sun-protective practices, by applying a questionnaire during their routine check-up visits.

RESULTS

Of 70 solid-organ transplant recipients, 38 (54.3%) stated knowledge of hazardous consequences of sun exposure; however, only 28 (40%) had the knowledge of causal relationship between sun and skin cancer development. There were 31 patients (44.3%) who were unable to recall anybody giving any information to them about sun protection, and 40 patients (57.1%) had never visited a dermatology clinic. The 10 solid-organ transplant recipients (14.3%) who used sunscreen creams daily had been undergoing regular dermatologic examination. Regarding sun-protective clothing, only 8 patients (11.4%) had been wearing a suitable hat, long sleeves, and sunglasses when outdoors. There was a statistically significant difference between the groups who had visited a dermatology clinic versus those who had not regarding knowledge of sun protection, the causal relationship between sun exposure and skin cancer, the use of sunscreens, and use of sun-protective clothing (P < .05).

CONCLUSIONS

Our data showed that dermatologic examination and education of patients about skin cancer development and sunscreen measures improved the sun-protective habits of solid-organ transplant recipients. Therefore, orderly visits once or twice a year should be strongly advised for this patient population by their medical care providers.
