Evaluation of the incidence of melanoma and non-melanoma skin cancer in patients with systemic lupus erythematosus and systemic sclerosis.

The incidence of skin cancer in patients with systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) has only been investigated with retrospective studies enrolling a low number of patients. The aims of our study were to assess the incidence of skin cancer in two large cohorts of patients, one with SLE and the other with SSc and investigating possible risk factors. Ninety SLE, 53 SSc patients and 392 control subjects were enrolled. A questionnaire including personal and medical details was fulfilled. The severity of photoaging, photosensitivity and sun exposure habits was assessed. Skin lesions were evaluated using a video-dermatoscope. Suspicious lesions were surgically removed. The incidence of skin cancer was not different to those of controls. However, a decrease in the incidence of basal cell carcinoma was found in patients with SLE. This finding associated negatively with photosensitivity. SSc patients with skin malignancies did not report photosensitivity and did not adopt a careful photoprotection. A positive association was found between skin cancer and diffuse cutaneous sclerosis, pitting scars, severe photoaging and treatment with Iloprost. Regular avoidance of sun exposure and photoprotection are effective in reducing the development of skin cancer in patients with autoimmune diseases.

Impact of the COVID-19 Pandemic on the Surgical Management of Head and Neck Non-Melanoma Skin Cancers in a Maxillofacial Center of Cluj-Napoca.

Background: The COVID-19 era has been a bleak period for both cancer and non-cancer patients, with delayed non-emergency treatments, such as for non-melanoma skin cancer (NMSC). This study aimed to evaluate how the treatment of NMSC patients was influenced by the management of the COVID-19 pandemic in an Eastern European Maxillofacial Surgery center. Materials and Methods: A total of 176 patients with a histopathological diagnosis of head and neck NMSC who were surgically treated in Cluj-Napoca Emergency County Hospital between 2016 and 2022 were included in this study, and divided into two samples, pre-pandemic (2016-2019) and COVID-19 (2020-2022) periods. Results: The pandemic presented with a decrease of 46.15% in patients' hospitalization, with wealthy and educated patients being prevalent. Even if the waiting time for surgery was increased, the stage of cancer and preference method for reconstruction did not differ. Despite the lower addressability of NMSC patients during the pandemic, there were no changes in surgical treatment. Conclusions: During COVID-19, the number of patients was reduced, with a longer waiting time for surgery, but without any changes in tumor stage and treatment preferences. However, the benefit of removing a cancer tumor is higher compared to the risk of developing COVID-19 infection during hospitalization.

Risk of Skin Cancer in Patients with Psoriasis: Single-Center Retrospective Study Comparing Anti-TNFα and Phototherapy.

Background: The risk of developing non-melanoma skin cancers (NMSCs) in patients with psoriasis is highly debated, and, to date, there is no unambiguous consensus opinion. Psoriasis is known to be related to an increased likelihood of other comorbidities such as psoriatic arthritis, obesity, metabolic syndrome, depression, and cardiovascular disease. Regarding cancer risk, previous studies have reported a greater tendency for the development of cutaneous T-lymphomas and colon, breast, kidney, and lung cancers. Furthermore, data from network meta-analyses have shown that patients with psoriasis have a higher risk of developing squamous cell carcinomas (SCCs) and/or basal cell carcinomas (BCCs). Multiple factors may contribute to the development of NMSCs in psoriatic patients, ranging from immunosuppression induced by biologic agents to previous phototherapy. However, the extent to which each factor may impact this risk has not been entirely assessed. The aim of this study was to evaluate the risk of developing NMSCs in patients with psoriasis observed for at least 5 years, by directly comparing patients only treated with phototherapy and patients treated with anti-tumor necrosis factor α (TNFα) agents, naive to other systemic treatments or phototherapy. Methods: We conducted a single-center retrospective study at Siena University Hospital, Italy, on 200 adult patients with psoriasis divided into two groups: (i) group 1, including 100 patients treated with narrow-band UVB phototherapy (nb-UVB), and (ii) group 2, including 100 patients treated with anti-TNFα. The patients included in group 2 had to be naive to cDMARDs and biologics and treated with anti-TNFα continuously for 5 years without loss of efficacy. All patients were observed for 5 years and underwent annual dermatologic examinations to assess for the occurrence of BCC or SCC. Results: A total of 34 out of 100 patients treated with phototherapy had one BCC or one SCC and 10 out of 34 developed two skin cancers. In particular, five had both types (one BCC and one SCC), and five had two BCCs. Conclusions: The results of our study highlight how the risk of developing NMSCs is greater in patients undergoing phototherapy compared to those treated with anti-TNFα. It also draws attention to the consideration that patients with scalp psoriasis might need closer follow-up as they could be more at risk of developing NMSCs.

Epidemiological and clinical analysis of exposure-related factors in non-melanoma skin cancer: A retrospective cohort study

BackgroundThe incidence of non-melanoma skin cancers (NMSCs) increased over last decades, probably due to environmental concerns or to the increase of frail patients with age related comorbidities. Currently, the relationship of increasing global skin cancer rates with increased ultraviolet radiations (UVRs) resulting from stratospheric ozone depletion, global warming, and air pollution from fossil-fuel combustion. AimsWe conducted a retrospective epidemiological study including 546 NMSC patients managed at the Dermatology Unit of the Tor Vergata Hospital to highlight different trends of sun exposure or different comorbidities. MethodsDescriptive and inferential statistical analyses were performed to evidence differences between continous variable and Spearman rank test for dicotomical variables. Charlson Comorbidity Index was calculated to obtain the 10-years survival rate in order to identify the mean comorbidity burden of our patients. ResultsConsidering patients with comorbidities (73.81%), actinic keratoses (AKs) was the most frequent lesion. In patients with a history of previous melanoma, basal cell carcinoma (BCC) was predominant (ANOVA test, p < 0.05) with a statistically significant correlation (rho = 0.453; p < 0.01). Squamous cell carcinoma (SCC) showed a higher rate in arterial hypertension patients, followed by the chronic heart failure and hematologic neoplasms (60%, 29.7% and 32.1%, respectively) groups. Men were more affected than women, representing 61.54% of patients. Chronic sun exposure is directly correlated with SCC rho = 0.561; p < 0.01), whereas BCC correlated with a history of sunburns (rho = 0.312; p < 0.05). ConclusionsHistory of photo-exposition had an important role on NMSC development especially for work or recreational reasons. Sex, age, and presence of comorbidities influenced different NMSC types. BCC was more frequent in younger patients, associated with melanoma and sunburns. The presence of SCC is associated with older patients and the hypertension group. AKs were diagnosed predominantly in oldest men, with a chronic sun-exposure history, and hematologic neoplasms group.

Exploring the impact of TGF-β family gene mutations and expression on skin wound healing and tissue repair.

Transforming Growth Factor-Beta (TGF-β) signalling pathway is of paramount importance in the processes of wound healing, epidermal integrity maintenance and development of skin cancer. The objective of this research endeavour was to clarify the impact of gene mutations and variations in expression within TGF-β family on mechanisms of tissue repair, as well as to identify potential targets for therapeutic purposes in non-melanoma skin cancer (NMSC). The methods utilized in this study involved obtaining RNA-seq data from 224 NMSC patients and paired normal skin tissues from the PRJNA320473 and PRJEB27606 databases. The purpose of the differential gene expression analysis was to identify genes whose expression had changed significantly. In order to evaluate the effects and interrelationships of identified gene variants, structural analysis with AlphaFold and PDB data and network analysis with the STRING database were both utilized. Critical gene expression was externally validated through the utilization of the GEPIA database. Tumour tissues exhibited a notable upregulation of genes associated with the TGF-β pathway, specifically MMP1, MMP3, MMP9, EGF, COL3A1 and COL1A2, in comparison with normal tissues. As indicated by the central node status of these genes in the network analysis, they play a crucial role in the progression of NMSCs. The results of the structural analysis suggested that mutations might cause functional disruptions. External validation of the upregulation confirmed the expression trends and emphasized the biomarker potential of the upregulated genes. In conclusion, this research offered thorough examination of molecular modifications that occur in TGF-β family genes, which are linked to cutaneous wound healing and NMSC. The modified expression of the identified hub genes may represent innovative targets for therapeutic intervention.

Outcomes and characteristics of nonmelanoma skin cancers in patients with myeloproliferative neoplasms on ruxolitinib

AbstractNonmelanoma skin cancers (NMSCs) in ruxolitinib-treated patients with myeloproliferative neoplasms behave aggressively, with adverse features and high recurrence. In our cohort, mortality from metastatic NMSC exceeded that from myelofibrosis. Vigilant skin assessment, counseling on NMSC risks, and prospective ruxolitinib-NMSC studies are crucial.

Incidence of melanoma and non-melanoma skin cancer in patients with celiac disease: a systematic review and meta-analysis.

There is conflicting observational evidence regarding the association between skin cancer and celiac disease (CD). The purpose of this review was to investigate the incidence rate ratio (IRR) of skin cancer incidence between patients with and without CD. MEDLINE and EMBASE databases were searched on October 27th, 2021 and eight articles were identified for review. Quality assessment was conducted using the Newcastle Ottawa Scale. Seven articles were included in meta-analysis for a pooled estimate of IRR across all skin cancers, malignant melanoma (MM), and non-melanoma skin cancers (NMSC). In total, 74,860 CD patients were followed for 710,214 person-years in the meta-analysis. Overall combined incidence was 99.8 cases per 100,000 person-years. Meta-analysis of all skin cancer incidence showed no significant difference in CD patients compared to controls (IRR: 1.06; 95% CI: 0.95, 1.17; p=0.29; I2: 0%). Five studies reported on MM incidence; there was no significant difference in incidence compared to controls (IRR: 0.87, 95% CI: 0.72, 1.06; p=0.22; I2: 9%). Five studies reported on NMSC incidence, revealing a significantly increased risk of NMSC in CD patients (IRR: 1.14; 95% CI: 1.01, 1.28; p=0.04; I2: 0%). Our findings suggest a significantly increased incidence of NMSC in CD patients compared to control data and no significant association between CD and MM incidence. The findings are limited by the quantity and quality of the evidence. Nonetheless, clinicians should emphasize the importance of sun protection, such as sunscreen usage and self-examination for patients with CD.

BI31 Hereditary haemochromatosis: a risk factor for nonmelanoma skin cancer?

Abstract Hereditary haemochromatosis (HH) is an autosomal recessive disease resulting in excessive levels of iron. In a recent study, in a US population of 448 patients diagnosed with HH, a positive association between HH and nonmelanoma skin cancers (NMSCs) was observed (Pan CX, Yang K, Lau CB et al. Non-melanoma skin cancer in patients with hereditary hemochromatosis: a case–control study. J Am Acad Dermatol 2023; 88:692–4). The authors also reported that, among those who required more frequent venesection, the risk of basal cell carcinoma (BCC) was particularly elevated. In terms of the possible pathomechanism, the authors noted that oxidative stress represents a key component in the pathogenesis of both HH and BCC. Ireland has the highest prevalence of HH in the world, with research suggesting approximately 1 in 83 people is predisposed. For this reason, a study was undertaken to determine if a similar association could be observed in an Irish population. A single-centre retrospective cross-sectional analysis was undertaken on a database of patients with haemochromatosis attending the venesection department of a tertiary referral centre over 25 years (1997–2022). All histologically diagnosed NMSCs within this patient group were then recorded. Ethical approval was granted by the local hospital ethics committee. There were a total 1480 patients in the database, 65% Male (n = 956). Five were excluded due to insufficient data. Thus, 1475 patients were analysed, 64% male (n = 949). The mean current age was 60 years (range: 19–100). Only 52/1475 patients (3.5%) had a histologically diagnosed NMSC, 52% male (n = 27). HH genetic mutation: C282Y homozygous (n = 29); H63D homozygous (n = 5); C282Y/H63D compound heterozygous (n = 11); and data not recorded (n = 7). Mean ferritin at HH diagnosis 575 (range: 0–8413). Forty-three patients were diagnosed with a BCC, 58% male (n = 25), with a total of 94 BCCs. Mean age was 67 years at first NMSC diagnosis. Histological classification: nodular (n = 48); superficial (n = 19); unclassified (n = 18); infiltrative (n = 5); micronodular (n = 3); and basosquamous (n = 1). Eleven patients were diagnosed with a squamous cell carcinoma (SCC), with a total of 21 SCCs. This study had limitations. It was a single-centre, retrospective study analysing only histologically confirmed NMSCs. It is acknowledged that a small proportion of NMSCs may be diagnosed clinically, specifically superficial BCCs without histological confirmation. Only records with histology available in our institution were recorded, and it is possible that NMSCs were excised in other institutions, potentially leading to an under-representation of NMSC incidence. The proportion of patients diagnosed with NMSCs in this cohort was relatively low, in contrast to the findings reported by Pan et al. This study indicates that HH is unlikely to represent an independent risk factor.

A first census of skin cancer specialist nurses across UK secondary care trusts

BackgroundSkin cancer specialist nurses (SCSNs) support patients and work alongside healthcare professionals throughout the care pathway. Skin cancer management is rapidly evolving, with increasing and more complex treatment options now available, so the need for patient support is growing. While SCSNs are a major source of that support, the provision of SCSN resource across the UK has never previously been assessed. We therefore undertook a first SCSN census on 1st June 2021.MethodsAn electronic survey was disseminated to UK hospital trusts and registered skin cancer healthcare professionals. Responses were identifiable only by the respective trust name.Results112 responses from 87 different secondary care trusts were received; 92% of trusts reporting having at least 1 established SCSN post. Average SCSN staffing per trust was 2.4 (range 0–7) whole time equivalents, managing an average caseload of 83 (range 6–400) patients per week. SCSN workload had increased in 82% hospitals in the previous year and 30% of trusts reported being under-resourced. Most SCSN time was spent managing melanoma (as opposed to non-melanoma skin cancer) patients linked to surgical services. Regional variations existed, particularly associated with provision of lymphoedema services, nurse prescribing skills and patient access to clinical trials. The COVID-19 pandemic was associated with a marked increase in SCSN-led telemedicine clinics, but loss of training and education opportunities.ConclusionsSCSNs based in secondary care hospitals play a major role supporting both clinicians and patients throughout the care pathway. This first UK census confirmed that SCSN workload is increasing and in one third of hospital trusts, the work was reported to outstrip the staffing available to manage the volume of work. Regional variations in SCSN resource, workload and job role, as well as availability of certain skin cancer services were identified, providing valuable information to healthcare commissioners concerned with service improvement.

Non-Melanoma Skin Cancer and Vitamin D: The "Lost Sunlight" Paradox and the Oxidative Stress Explanation.

UV radiation (UVR) is responsible for inducing both harmful and beneficial effects on skin health. Specifically, it has been reported to disrupt oxidant and antioxidant levels, leading to oxidative stress conditions in skin tissue. This phenomenon might trigger photo-carcinogenesis, resulting in melanoma, NMSC (non-melanoma skin cancer), such as BCC (basal cell carcinoma) and SCC (squamous cell carcinoma), and actinic keratosis. On the other hand, UVR is essential for the production of adequate vitamin D levels, a hormone with important antioxidant, anticancer and immunomodulatory properties. The exact mechanisms implicated in this two-fold action are not well understood, as there still no clear relation established between skin cancer and vitamin D status. Oxidative stress seems to be a neglected aspect of this complex relation, despite its role in both skin cancer development and vitamin D deficiency. Therefore, the aim of the present study is to examine the correlation between vitamin D and oxidative stress in skin cancer patients. A total of 100 subjects (25 with SCC, 26 with BCC, 23 with actinic keratosis, and 27 controls) were assessed in terms of 25-hydroxyvitamin D (25(OH) D) and redox markers such as thiobarbituric acid reactive substances (TBARS), protein carbonyls, total antioxidant capacity (TAC) in plasma, glutathione (GSH) levels and catalase activity in erythrocytes. The majority of our patients revealed low vitamin D levels; 37% of the subjects showed deficiency (<20 ng/mL) and 35% insufficiency (21-29 ng/mL). The mean 25(OH) D level of the NMSC patients (20.87 ng/mL) was also found to be significantly lower (p = 0.004) than that of the non-cancer patients (28.14 ng/mL). Furthermore, higher vitamin D levels were also correlated with lower oxidative stress (positive correlation with GSH, catalase activity TAC index and negative correlation with TBARS and CARBS indices). NMSC patients diagnosed with SCC showed lower catalase activity values compared to non-cancer patients (p < 0.001), with the lowest values occurring in patients with a chronic cancer diagnosis (p < 0.001) and vitamin D deficiency (p < 0.001). Higher GSH levels (p = 0.001) and lower TBARS levels (p = 0.016) were found in the control group compared to the NMSC group, and to patients with actinic keratosis. Higher levels of CARBS were observed in patients with SCC (p < 0.001). Non-cancer patients with vitamin D sufficiency showed higher TAC values compared to non-cancer patients with vitamin D deficiency (p = 0.023) and to NMSC patients (p = 0.036). The above-mentioned results indicate that NMSC patients reveal increased levels of oxidative damage markers compared to control levels, while vitamin D status plays a critical role in the determination of individuals' oxidative status.

Psoriasis Patients Treated With Methotrexate Have an Increased Risk of Nonmelanoma Skin Cancer: A Systematic Review and Meta-Analysis.

Both psoriasis and methotrexate are associated with an increased risk of nonmelanoma skin cancer. The effect of methotrexate on the development of nonmelanoma skin cancer in patients with psoriasis is currently unknown. To evaluate this relationship, a systematic review of the literature was conducted using databases including Ovid Medline (from 1946), Scopus (from 1970), and Embase (from 1974) through June 2019. Observational comparative and case-control studies comparing psoriasis patients treated with methotrexate to those not treated with methotrexate with data on the subsequent development of nonmelanoma skin cancer in both cohorts were included based on prespecified criteria. Two reviewers analyzed all studies for relevant data, which were analyzed using OpenMeta-Analyst statistical software. Quality was assessed with the Newcastle-Ottawa method. Nine cohort and case-control comparative studies of 1,486 screened abstracts met the inclusion criteria. Of 11,875 reported patients with psoriasis, 2,192 were taking methotrexate. A meta-analysis demonstrated an odds ratio of 2.8 (95% confidence interval = 1.47-5.39; p = 0.002) for nonmelanoma skin cancer development in patients with psoriasis taking methotrexate compared with those not taking methotrexate. Based on these findings, psoriasis patients treated with methotrexate are at a significantly increased (2.8 times higher) risk of developing nonmelanoma skin cancer. Risk counseling can improve healthcare outcomes in patients with psoriasis.

A novel tool for predicting the dose distribution of non-sealed 188 Re (Rhenium) resin in non-melanoma skin cancers (NMSC) patients.

High-dose rate brachytherapy using a non-sealed 188 Rhenium resin (188 Re) is a recently approved treatment option for non-melanoma skin cancer (NMSC). The treatment goal is to deliver a personalized absorbed dose to the deepest point of neoplastic infiltration corresponding to the minimal target dose. The treatment consists of the application of a 188 Re-based resin over a plastic foil placed on the target skin surface. However, there is no treatment planning tool to assess the 188 Re activity needed for a personalized treatment. The paper aims to present a novel Monte Carlo (MC)-based tool for 188 Re-based resin activity and dose calculation, experimentally validated using Gafchromic EBT3 films. MC simulations were carried out using FLUKA modeling density and composition of 188 Re resin. The MC-based look up table (LUT) was incorporated in an ad hoc developed tool. The proposed tool allows the personalized calculation of treatment parameters (i.e., activity to be dispensed, the treatment duration, and dose volume histograms), according to the target dimension. The proposed tool was compared using Bland-Altman analysis to the previous calculation approaches conducted using VARSKIN in a retrospective cohort of 76 patients. The tool was validated in ad hoc experimental set ups using a stack of calibrated Gafchromic EBT3 films covered by a plastic film and exposed using a homogenous activity distribution of 188 Re eluate and a heterogeneous activity distribution of 188 Re resin mimic the patient treatment. The agreement between the proposed tool and VARSKIN was evaluated on the investigated cohort with median range of target area, target depth, and treatment time equal to 4.8 [1.0-60.1]cm2 , 1.1 [0.2-3.0]mm, and 70 [21-285]min, with a median range of target dose (Gy) of 23.5 [10-54.9]. The calculated minimal target doses, ranged from 1% to 10% for intermediate target depths (1.2±0.7mm), while showing significant differences in the estimation of superficial (maximal) target doses. The agreement between MC calculation and measurements at different plans in a stack of Gafchromic EBT3 films was within 10% for both the homogenous and heterogeneous activity distribution of 188 Re. Worst agreements were observed for absorbed doses lower than 0.3Gy. Our results support the implementation of our MC-based tool in the practical routine for calculating the 188 Re resin activity and treatment parameters necessary for obtaining the prescribed minimal target dose.

A comparison of skin grafts versus local flaps for facial skin cancer from the patient perspective: protocol for a feasibility study.

This is a protocol to assess feasibility of conducting a prospective cohort study comparing local flaps versus skin grafts for surgical excision of skin cancer from the face. Skin cancer is the most common malignancy worldwide and the face is one of the most common locations of occurrence. Surgical excision is the most popular treatment for small lesions of the face. Defects can be reconstructed using local flaps or skin grafts. There is a paucity of literature evaluating outcomes after skin cancer surgery from the patient's perspective using valid measurement tools. The purpose of this study is to assess the feasibility of conducting a prospective observational cohort study. The primary outcomes include recruitment rates, eligibility rate, compliance of intervention and rate of completion of the primary outcome (FACE-Q scales) at 3 months. Secondary outcomes include examining patient characteristic and FACE-Q score differences between local flaps to skin grafts and adverse events. This study is a prospective cohort study consisting of an anticipated 30 patients aged ≥18years. The study population will consist of a consecutive sample of non-melanoma facial skin cancer patients undergoing a skin graft or local flap. Patients will be followed and evaluated with the FACE-Q questionnaire at 2weeks, 3months, 6months and 1 year post-operation. The following criteria will determine success: patients who meet eligibility criteria >70%; recruitment rate >70%; compliance with intervention >90%; rate of completion of full-scale prospective study primary outcome (FACE-Q at 3months) >80%; retention rate at 6-month follow-up visit >70%. The findings of this study will be used to guide the sample size calculation for a future, large-scale prospective study.Trial registration: ClinicalTrials.gov (NCT04842279).

Management of Non-Melanoma Skin Cancer: Radiologists Challenging and Risk Assessment.

Basal cell carcinoma, squamous cell carcinoma, and Merkel cell carcinoma are the three main types of nonmelanoma skin cancers and their rates of occurrence and mortality have been steadily rising over the past few decades. For radiologists, it is still difficult to treat patients with advanced nonmelanoma skin cancer. Nonmelanoma skin cancer patients would benefit greatly from an improved diagnostic imaging-based risk stratification and staging method that takes into account patient characteristics. The risk is especially elevated among those who previously received systemic treatment or phototherapy. Systemic treatments, including biologic therapies and methotrexate (MTX), are effective in managing immune-mediated diseases; however, they may increase susceptibility to NMSC due to immunosuppression or other factors. Risk stratification and staging tools are crucial in treatment planning and prognostic evaluation. PET/CT appears more sensitive and superior to CT and MRI for nodal and distant metastasis as well as in surveillance after surgery. The patient treatment response improved with advent and utilization of immunotherapy and different immune-specific criteria are established to standardized evaluation criteria of clinical trials but none of them have been utilized routinely with immunotherapy. The advent of immunotherapy has also arisen new critical issues for radiologists, such as atypical response pattern, pseudo-progression, as well as immune-related adverse events that require early identification to optimize and improve patient prognosis and management. It is important for radiologists to have knowledge of the radiologic features site of the tumor, clinical stage, histological subtype, and any high-risk features to assess immunotherapy treatment response and immune-related adverse events.

Health-related quality of life and associated factors among non-melanoma skin cancer patients: a cross-sectional study.

Non-melanoma skin cancer (NMSC) is a common malignant tumor that can lead to disability and a high recurrence rate, thus affecting the health-related quality of life (HRQoL) of patients. However, the HRQoL and its associated factors among Chinese patients with NMSC remain unknown. Considering HRQoL is a comprehensive indicator to assess an individual's health and well-being, as well as to provide a basis for future treatment decisions and care interventions, we investigated Chinese NMSC patients to assess the status of HRQoL, and to explore the associated factors of HRQoL. This cross-sectional study was conducted at the largest dermatology hospital in China from November 2017 to February 2022. Participants were over 18 years, diagnosed with NMSC by pathological examination, and able to provide informed consent. A consecutive sampling technique was used and 202 eligible patients with NMSC were surveyed. Dermatology Life Quality Index, general information questionnaire, Athens Insomnia Scale, and Self-rating Anxiety Scale were used to measure their HRQoL and relevant information. Descriptive statistics, non-parametric test and Spearman's correlation analyses were used to compare the differences and assess the relationships between participants' demographic and clinical factors, sleep, anxiety, and HRQoL. Multiple linear regression analysis was performed to identify factors associated with HRQoL. A total of 176 NMSC patients (mean age 66 years, including 83 males and 93 females) were included. The median score of HRQoL was 3 [1, 7], and 116 (65.9%) NMSC patients' HRQoL was negatively affected. The score of the symptom and feeling domain was the highest 2 [1, 3], NMSC patients with squamous cell carcinoma and extramammary Paget disease had a significantly lower HRQoL than patients with basal cell carcinoma (P<0.05). Primary skin diseases, long-term history of mechanical stimulation, poor sleep, and anxiety were the associated factors of the HRQoL, comprising 43.5% of the total variance. Most patients with NMSC live with poor HRQoL in China. It is necessary to provide timely assessment and develop targeted strategies to improve NMSC patients' HRQoL, such as multiple forms of health education, psychological care for the target population, and effective measures to improve patients' sleep.

Analysis of image-guided superficial radiation therapy (IGSRT) on the treatment of early-stage non-melanoma skin cancer (NMSC) in the outpatient dermatology setting

BackgroundInterest in image-guidance superficial radiation therapy (IGSRT) for the treatment of early-stage non-melanoma skin cancer (NMSC) has resurfaced given its low complication rates, superior cosmesis and local control and cure rates. In addition, it has been recommended by the American Academy of Dermatology (AAD) for early-stage NMSC in patients who are considered poor surgical candidates.Methods1899 NMSC lesions were treated with energies ranging from 50 to 100 kilovoltage (kV), for a mean of 20.2 fractions, and treatment dose of 5364.4 centigray (cGy). Lesions were treated for a mean of 7.5 weeks and followed for 65.5 weeks. SAS studio was used to conduct Kaplan–Meier analysis to calculate local control rates and account for differences in follow-up intervals. A log-rank test was used to calculate statistical differences between histologies.ResultsAbsolute lesion control was achieved in 99.7% of the patients after an average of 7.5 weeks of treatment, with a stable control rate of 99.6% when the follow-up duration was over 12 months. 95% of lesions with toxicity scoring received a Radiation Treatment Oncology Group Toxicity (RTOG) score of 1 or 2.ConclusionIGSRT has a high safety profile, can achieve superior cosmesis and should be considered first-line for treating early-stage NMSC tumors as cure rates have been shown to be effective in all NMSC on early follow-up.

Same Day Biopsy and Treatment of Non-Melanoma Skin Cancer in Patients with Field Cancerization: A Retrospective Chart Study.

Patients with field cancerization will develop numerous superficial non-melanoma skin cancers (NMSCs). Treating patients with field cancerization can be challenging and burdensome due to the numerous non-melanoma skin cancers (NMSCs) they develop and the frequent dermatology visits required for biopsy and treatment. The success rate of diagnosing and treating lesions suspicious for NMSCs on the same day is measured, immediately after biopsy. We retrospectively reviewed records of patients with same day lesion diagnosis and curettage treatment to determine diagnostic accuracy, treatment failure, and number needed to treat to reduce a follow-up treatment. A total of 237 lesions underwent same day biopsy and treatment, of which the majority were NMSC (66%) or actinic keratosis (23%). Patients had at least 3 months and a median of 17 months follow-up. A total of 20 lesions either recurred or were deemed to require additional treatment. The number needed to treat (NNT) to prevent one follow-up treatment was 1.3. Limitations: sample size limited ability to determine risk factors for treatment failure. Simultaneous diagnosis and treatment of superficial NMSCs is a successful way of improving efficiency and patient satisfaction.
