Contribution of skin cancer to overall healthcare costs of lung transplantation in Queensland, Australia

BACKGROUND

Skin cancers are a major source of morbidity in lung transplant recipients, but the relative costs associated with their treatment are unknown.

METHODS

We prospectively followed 90 lung transplant recipients from enrollment in the Skin Tumors in Allograft Recipients study in 2013-2015, until mid-2016. We undertook a cost analysis to quantify the health system costs relating to the index transplant episode and ongoing costs for 4 years. Linked data from surveys, Australian Medicare claims, and hospital accounting systems were used, and generalized linear models were employed.

RESULTS

Median initial hospitalization costs of lung transplantation were AU$115,831 (interquartile range (IQR) $87,428-$177,395). In total, 57 of 90 (63%) participants were treated for skin cancers during follow-up at a total cost of AU$44,038. Among these 57, total government costs per person (mostly of pharmaceuticals) over 4 years were median AU$68,489 (IQR $44,682-$113,055) vs AU$59,088 (IQR $38,190-$94,906) among those without skin cancer, with the difference predominantly driven by more doctors' visits, and higher pathology and procedural costs. Healthcare costs overall were also significantly higher in those treated for skin cancers (cost ratio 1.50, 95%CI: 1.09, 2.06) after adjusting for underlying lung disease, age on enrollment, years of immunosuppression, and the number of treated comorbidities.

CONCLUSIONS

Skin cancer care is a small component of overall costs. While all lung transplant recipients with comorbidities have substantial healthcare costs, those affected by skin cancer incur even greater healthcare costs than those without, highlighting the importance of skin cancer control.

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.

Multimodal Transplant-clinic-based Skin Cancer Prevention Education for Organ Transplant Recipients: Feasibility Study

We studied the feasibility of transplant-clinic staff routinely providing primary prevention advice to lung transplant recipients at high risk of skin cancer.

Methods

Patients enrolled by a transplant-clinic study nurse completed baseline questionnaires and received sun-safety brochures. For the 12-mo intervention, transplant physicians were alerted to provide standard sun-protection advice (use of hat, long sleeves, and sunscreen outdoors) by sun-advice prompt cards attached to participants' medical charts at each clinic visit. Patients indicated receiving advice from their physician and from study personnel via an exit-card postclinic, and at final study clinics, they also reported their sun behaviors by questionnaire. Feasibility of the intervention was measured by patients' and clinic staff's study engagement; effectiveness was assessed by calculating odds ratios (ORs) for improved sun protection, using generalized estimating equations.

Results

Of 151 patients invited, 134 consented (89%), and 106 (79 %) (63% male, median age 56 y, 93% of European descent) completed the study. Odds of receiving sun advice from transplant physicians and study nurses rose after the intervention compared with baseline (ORs, 1.67; 95% confidence interval [CI], 0.96-2.96 and 3.56; 95% CI, 1.38-9.14, respectively). After 12 mo of regular transplant-clinic advice, odds of sunburn decreased (OR, 0.59; 95% CI, 0.13-2.60), and odds of applying sunscreen (OR, 1.93; 95% CI, 1.20-3.09) almost doubled.

Conclusions

Encouragement of primary prevention of skin cancer among organ transplant recipients by physicians and nurses during routine transplant-clinic visits is feasible and appears to be effective.

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.

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.

Polygenic Risk Scores Stratify Keratinocyte Cancer Risk among Solid Organ Transplant Recipients with Chronic Immunosuppression in a High Ultraviolet Radiation Environment

Solid organ transplant recipients (SOTRs) have elevated risks for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), especially in high UVR environments. We assessed whether polygenic risk scores can improve the prediction of BCC and SCC risks and multiplicity over and above the traditional risk factors in SOTRs in a high UV setting. We built polygenic risk scores for BCC (n = 594,881) and SCC (n = 581,431) using UK Biobank and 23andMe datasets, validated them in the Australian QSkin Sun and Health Study cohort (n > 6,300), and applied them in SOTRs in the skin tumor in allograft recipients cohort from Queensland, Australia, a high UV environment. About half of the SOTRs with a high genetic risk developed BCC (absolute risk = 45.45%, 95% confidence interval = 33.14-58.19%) and SCC (absolute risk = 44.12%, 95% confidence interval = 32.08-56.68%). For both cancers, SOTRs in the top quintile were at >3-fold increased risk relative to those in the bottom quintile. The respective polygenic risk scores improved risk predictions by 2% for BCC (area under the curve = 0.77 vs. 0.75, P = 0.0691) and SCC (area under the curve = 0.84 vs. 0.82, P = 0.0260), over and above the established risk factors, and 19.03% (for BCC) and 18.10% (for SCC) of the SOTRs were reclassified in a high/medium/low risk scenario. The polygenic risk scores also added predictive accuracy for tumor multiplicity (BCC R2 = 0.21 vs. 0.19, P = 3.2 × 10-3; SCC R2 = 0.30 vs. 0.27, P = 4.6 × 10-4).

Low participation in preventative health measures in a cohort of liver transplant recipients: A cross-sectional analysis

BACKGROUND

Despite high rates of infection and malignancy post-solid organ transplant, there are little data on patient participation in preventative health care.

METHODS

We conducted a cross-sectional survey of post-liver transplant patients to evaluate insight into transplant-associated infective and neoplastic risks, and receipt of vaccination and cancer surveillance in accordance with Australian and local institution-specific guidelines. Descriptive analyses were used to assess characteristics potentially influencing adherence.

RESULTS

Of 219 patients surveyed, adherence to bowel cancer surveillance was significantly reduced in those distant from transplantation compared with those recently transplanted (95.8% if transplanted ≤ 5 years ago vs. 68.3% if transplanted > 5 years ago, P < .001). Skin cancer surveillance participation with annual physician-directed examination was low (42.9%), particularly in younger patients (29.5% in < 50yo vs. 48.1% in ≥ 50yo, P = .01), who were also less adherent to vaccination recommendations (72.1% in < 50yo vs. 87.3% in ≥ 50yo, P = .008).

CONCLUSIONS

This is the first analysis of preventative healthcare participation in a cohort of Australian liver transplant recipients, revealing concerning adherence to bowel and skin cancer surveillance recommendations. Major interventions to avoid preventable disease in this high-risk cohort are warranted.

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.

Omega-3 fatty acid intake and decreased risk of skin cancer in organ transplant recipients

PURPOSE

Organ transplant recipients have over 100-fold higher risk of developing skin cancer than the general population and are in need of further preventive strategies. We assessed the possible preventive effects of omega-3 polyunsaturated fatty acid (PUFA) intake from food on the two main skin cancers, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) in kidney and liver transplant recipients.

METHODS

Adult kidney or liver transplant recipients transplanted for at least 1 year and at high risk of skin cancer were recruited from the main transplant hospital in Queensland, 2012-2014 and followed until mid-2016. We estimated their dietary total long-chain omega-3 PUFAs and α-linolenic acid intakes at baseline using a food frequency questionnaire and ranked PUFA intakes as low, medium, or high. Relative risks (RRs_adj) of skin cancer adjusted for confounding factors with 95% confidence intervals (CIs) were calculated.

RESULTS

There were 449 transplant recipients (mean age, 55 years; 286 (64%) male). During follow-up, 149 (33%) patients developed SCC (median 2/person; range 1-40) and 134 (30%), BCC. Transplant recipients with high total long-chain omega-3 PUFA compared with low intakes showed substantially reduced SCC tumour risk (RR_adj 0.33, 95% CI 0.18-0.60), and those with high α-linolenic acid intakes experienced significantly fewer BCCs (RR_adj 0.40, 95% CI 0.22-0.74). No other significant associations were seen.

CONCLUSION

Among organ transplant recipients, relatively high intakes of long-chain omega-3 PUFAs and of α-linolenic acid may reduce risks of SCC and BCC, respectively.

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.

Bone marrow transplant recipients and their compliance with sun-protection measures in Queensland, Australia

There is no current published work on the sun-protection practices of bone marrow transplant recipients. The burden of post-transplant skin malignancy is a growing public health concern. This paper evaluates the compliance of bone marrow transplant recipients with advice about sun protection through a cross-sectional observational study involving participants completing a questionnaire regarding sun protection. Whilst most bone marrow transplant patients recalled receiving education (94%) and understood why they required additional precautions (84%), half did not practice adequate photoprotection. Future research should explore barriers to non-compliance with sun-protection measures in bone marrow transplant patients so additional interventions can be more targeted within this population.

Prevalence of Perineural Invasion in keratinocyte cancer in the general population and among organ transplant recipients

BACKGROUND/OBJECTIVES

Basal cell carcinomas (BCCs) and cutaneous squamous cell carcinomas (SCCs) are the most commonly encountered cancers in fair-skinned populations worldwide. Perineural invasion is associated with worse outcomes for patients with BCC or SCC. Estimates of perineural invasion prevalence range widely, likely reflecting non-representative patient samples. We sought to determine the prevalence of perineural invasion in BCC and SCC in the general population, as well as among cancers arising in solid organ transplant recipients.

METHODS

We retrospectively analysed histopathology reports of BCC and SCC from patients enrolled in the QSkin Study (a population-based cohort of 43 794 Queensland residents recruited 2010-2011) and the Skin Tumours in Allograft Recipients (STAR) study (a cohort of 509 high-risk kidney or liver transplant recipients at the Princess Alexandra Hospital, Brisbane, recruited 2012-2014.) We estimated the prevalence of perineural invasion (and 95% confidence interval) in BCC and SCC, respectively, and identified clinical factors associated with perineural invasion.

RESULTS

In QSkin, we observed 35 instances of perineural invasion in 9850 histopathologically confirmed BCCs (0.36%) and 9 instances of perineural invasion in 3982 confirmed SCC (0.23%) lesions. In the STAR cohort, we identified 4 lesions with perineural invasion in 692 BCCs (0.58%) and 16 reports of perineural invasion in 875 SCC lesions (1.9%).

CONCLUSIONS

These data suggest that the overall prevalence of perineural invasion in keratinocyte cancer is low, although perineural invasion prevalence may be slightly higher among organ transplant recipients when compared to the general population.

Keratinocyte Carcinomas: Current Concepts and Future Research Priorities

Cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC) are keratinocyte carcinomas, the most frequently diagnosed cancers in fair-skinned populations. Ultraviolet radiation (UVR) is the main driving carcinogen for these tumors, but immunosuppression, pigmentary factors, and aging are also risk factors. Scientific discoveries have improved the understanding of the role of human papillomaviruses (HPV) in cSCC as well as the skin microbiome and a compromised immune system in the development of both cSCC and BCC. Genomic analyses have uncovered genetic risk variants, high-risk susceptibility genes, and somatic events that underlie common pathways important in keratinocyte carcinoma tumorigenesis and tumor characteristics that have enabled development of prediction models for early identification of high-risk individuals. Advances in chemoprevention in high-risk individuals and progress in targeted and immune-based treatment approaches have the potential to decrease the morbidity and mortality associated with these tumors. As the incidence and prevalence of keratinocyte carcinoma continue to increase, strategies for prevention, including effective sun-protective behavior, educational interventions, and reduction of tanning bed access and usage, are essential. Gaps in our knowledge requiring additional research to reduce the high morbidity and costs associated with keratinocyte carcinoma include better understanding of factors leading to more aggressive tumors, the roles of microbiome and HPV infection, prediction of response to therapies including immune checkpoint blockade, and how to tailor both prevention and treatment to individual risk factors and needs.

Skin Cancer-Sun Knowledge and Sun Protection Behaviors of Liver Transplant Recipients in Turkey

The aim of this study was to compare liver transplant recipients (LTRs) with the general population regarding their knowledge of skin cancer, sun health, sun protection behaviors, and affecting factors. This cross-sectional study was conducted in Turkey between March 2016 and September 2016 with 104 LTRs and 100 participants from the general population group (GPG). The mean age of the LTRs was 53.2 ± 11.8 and that of the GPG was 42.7 ± 14.5. The LTRs' skin cancer and sun knowledge were significantly lower than in the GPG, but there was no difference between the two groups in terms of their sun protection behavior scores. The most commonly used sun protection behaviors of LTRs were not being outside and not sunbathing between 10 a.m. and 4 p.m., wearing clothing that covers the skin, and avoiding the solarium. Behaviors commonly practiced by the GPG were wearing sunglasses, wearing sunscreen with a sun protection factor of 15 or higher before going outside, wearing sunscreen at the beach, while swimming or doing physical activity outside, and reapplying it every 2 h. Results of our study will contribute to the development of education and training programs for LTRs on skin cancer. The results also demonstrated the importance of practicing adequate sun protection behaviors which will certainly impact their future health.

Long-term Change in the Risk of Skin Cancer After Organ Transplantation: A Population-Based Nationwide Cohort Study

Importance

The high risk of skin cancer after organ transplantation is a major clinical challenge and well documented, but reports on temporal trends in the risk of posttransplant cutaneous squamous cell carcinoma (SCC) are few and appear contradictory.

Objective

To study temporal trends for the risk of skin cancer, particularly SCC, after organ transplantation.

Design, Setting, and Participants

Population-based, nationwide, prospective cohort study of 8026 patients receiving a kidney, heart, lung, or liver transplant in Norway from 1968 through 2012 using patient data linked to a national cancer registry. The study was conducted in a large organ transplantation center that serves the entire Norwegian population of approximately 5.2 million.

Exposures

Receiving a solid organ transplant owing to late-stage organ failure, followed by long-term immunosuppressive treatment according to graft-specific treatment protocols.

Main Outcomes and Measures

Occurrence of first posttransplant SCC, melanoma, or Kaposi sarcoma of the skin. Risk of skin cancer was analyzed using standardized incidence ratios (SIRs) and, for SCC, multivariable Poisson regression analysis of SIR ratios, adjusting for 5-year time period of transplantation, different follow-up time, age, sex, and type of organ.

Results

The study cohort included 8026 organ transplant recipients, 5224 men (65.1%), with a mean age at transplantation of 48.5 years. Median follow-up time was 6.7 years per recipient; total follow-up time, 69 590 person-years. The overall SIRs for SCC, melanoma, and Kaposi sarcoma were 51.9 (95% CI, 48.4-55.5), 2.4 (95% CI, 1.9-3.0), and 54.9 (95% CI, 27.4-98.2), respectively. In those who underwent transplantation in the 1983-1987 period, the unadjusted SIR for SCC was 102.7 (95%, 85.8-122.1), declining to 21.6 (95% CI, 16.8-27.0) in those who underwent transplantation in the 2003-2007 period. Adjusting for different follow-up times and background population risks, as well as age, graft organ, and sex, a decline in the SIR for SCC was found, with SIR peaking in patients who underwent transplantation in the 1983-1987 period and later declining to less than half in patients who underwent transplantation in the 1998-2002, 2003-2007, and 2008-2012 periods, with the relative SIRs being 0.42 (95% CI, 0.32-0.55), 0.31 (95% CI, 0.22-0.42), and 0.44 (95% CI, 0.30-0.66), respectively.

Conclusions and Relevance

The risk of SCC after organ transplantation has declined significantly since the mid-1980s in Norway. Less aggressive and more individualized immunosuppressive treatment and close clinical follow-up may explain the decline. Still, the risk of SCC in organ transplant recipients remains much higher than in the general population and should be of continuous concern for dermatologists, transplant physicians, and patients.

Insect antimicrobial peptides: potential tools for the prevention of skin cancer

Antimicrobial peptides/proteins (AMPs) are biologically active molecules with diverse structural properties that are produced by mammals, plants, insects, ticks, and microorganisms. They have a range of antibacterial, antifungal, antiviral, and even anticancer activities, and their biological properties could therefore be exploited for therapeutic and prophylactic applications. Cancer and cancer drug resistance are significant current health challenges, so the development of innovative cancer drugs with minimal toxicity toward normal cells and novel modes of action that can evade resistance may provide a new direction for anticancer therapy. The skin is the first line of defense against heat, sunlight, injury, and infection, and skin cancer is thus the most common type of cancer. The skin that has been exposed to sunlight is particularly susceptible, but lesions can occur anywhere on the body. Skin cancer awareness and self-efficacy are necessary to improve sun protection behavior, but more effective preventative approaches are also required. AMPs may offer a new prophylactic approach against skin cancer. In this mini review, we draw attention to the potential use of insect AMPs for the prevention and treatment of skin cancer.
