Show moreBackground: Knowledge of the psychosocial impact of facial skin surgery on patients can help improve counselling strategies.Objectives: The objective was to measure the psychological impact of facial skin cancer surgery on patients over a 1-year period. Secondary objective was to meas-ure the difference between Mohs micrographic surgery (MMS) and conventional excision (CE) on these parameters.Methods: This observational survey study was conducted between March 2019 and July 2020. Patients who had facial skin surgery using MMS or CE were selected. Five surveys were conducted on four timepoints (preoperative, 1 week, 3 months and 1 year post-operative) measuring the quality of life, perceived stigmatization, body image, satisfaction with facial appearance and psychosocial distress.Results: A total of 228 patients (MMS 154 patients, CE 74 patients) were included for the analysis. Scores for quality of life did not significantly change, in the year after surgery (PCS-12 mean 50.5, SD 9.3 and MCS-12 50.6, SD 9.4); however, stigmatiza-tion (F (3, 235,39) 7,26, p < 0.01, d = −0.07), body image concerns (F (3, 198,28) = 3.75, p < 0.01, d = −0.14), satisfaction with facial appearance (F (3, 205,18) = 10.74, p < 0.01, d = 0.43) and psychosocial distress (F (3, 208,69) = 9.26, p < 0.01, d = −0.15) did change over time. The use of MMS or CE did not significantly affect outcome scores after 1 year.Conclusion: Patients receiving facial skin cancer surgery exhibited low scores for perceived stigmatization and body image concerns. Their quality of life was not statistically inf luenced by facial surgery, and their satisfaction with their facial appearance and psychosocial distress even improved after 1 year. The results suggest that the surgical treatment type (MMS or CE) does not inf luence the outcome. The overall results can help in counselling strategies to improve expectations for patients receiving facial surgery. Show less

Show moreBackground: Solid organ-transplant recipients (SOTR) have an increased risk of cutaneous squamous-cell carcinoma (cSCC), metastasis and death from cSCC. In immunocompetent patients with mucosal SCC, downregulation of HLA class I is associated with poor prognosis. Since the degree of HLA expression on tumor cells could play a role in immunogenicity and pathophysiology of cSCC metastasis, we hypothesized that decreased HLA expression is associated with an increased risk of metastasis.Methods: We compared HLA expression between primary metastasized cSCCs, their metastases, and nonmetastasized cSCCs from the same patients. Samples were stained for HLA-A, HLA-B/-C and quantified by calculating the difference in immunoreactivity score (IRS) of the primary cSCC compared with all nonmetastasized cSCCs. Results: The mean IRS score for HLA-B/C expression was 2.07 point higher in metastasized compared to nonmetastasized cSCCs (p = 0.065, 95 % CI -0.18-4.32). 83.3 % of the primary metastasized cSCCs had an IRS score of 4 or higher, compared to 42.9 % in non-metastasized cSCCs. Moderately to poorly differentiated cSCCs had more HLA class I expression compared to well-differentiated cSCCs. Conclusion: Contrary to immunocompetent patients, HLA-B/C expression tends to be upregulated in metastasized cSCC compared to non-metastasized cSCC in SOTR, suggesting that different tumor escape mechanisms play a role in SOTR compared to immunocompetent patients.

Show moreMechanical stress influences scarring of a surgical wound. Several lines have been proposed for the best excision direction. It is unknown if these lines still apply when the body posture changes. The objective is to measure the skin reaction force in four directions and determine the direction of least force. Secondary objective is to determine if the reaction force varies in a different body posture. Skin reaction force was measured with the compressiometer in 30 participants on four different locations (forearm/upper arm/shoulder blade/lower back) in four directions (0°–45°–90°–135°) and two body postures. The direction of least skin reaction force changed with a different body posture and was significant for the forearm (p < 0.01) and shoulder blade (p = 0.05) The skin reaction force in all four direction changed significantly in a different body posture, except the 45° line in the upper arm and shoulder blade. Our results demonstrate that the skin reaction force in four directions in four locations varies with change in body posture. Focus should therefore not only lay on choosing the right direction, but also on managing skin tension postoperatively. Show less

Show moreBackground The standard treatment for cutaneous squamous cell carcinoma (cSCC) is surgical excision. Failure to radically remove a cSCC is a risk for recurrence, progression and metastasis. Objectives This study investigates several risk factors for incomplete excision of cSCC. Methods All consecutive patients in a single institution treated with wide local excision for primary cSCC over a 10-year period were included in this study. Risk factors such as: gender, age, immunosuppression, tumour size, location, differentiation grade, tumour depth, perineural and lymphovascular invasion (PNI and LVI) were extracted from the database. Univariable and (if applicable) multivariable logistic regression analysis were used to identify risk factors (P < 0.05). Generalized estimating equations (GEEs) were used for multiple tumours within the same patients. Results A total of 566 patients with 1159 cSCC were identified. Univariable and multivariable logistic regression analysis showed that depth beyond the dermis (OR: 5.7 95% CI: 3.1-10.5) was the only risk factor for incomplete excision of cSCC. Immunosuppression was only a risk factor in the deep plane (OR: 2.5, 95% CI: 1.3-4.6). Conclusion Tumour depth beyond the dermis is the most important risk factor for incomplete excision of cSCC. Immunosuppression is a risk factor in the deep plane but its relevance is uncertain. Immunosuppression is not consistently included in the current cSCC staging systems, but care should be taken when treating these patients. Show less

Show moreThe incidence of cutaneous squamous cell carcinoma (cSCC) is rapidly increasing. A growing part of this patient group is formed by immunocompromised patients, for example organ-transplant recipients (OTR). Although over 90% of the cSCC show a relatively harmless clinical behaviour, there is also a chance of developing advanced cSCC and metastases. Locally advanced cSCC are defined as cSCC that have locally advanced progression and are no longer amenable to surgery or radiation therapy. Better understanding of the clinical behaviour of cSCC is essential to discriminate between low- and high-risk cSCC. Staging systems are important and have recently been improved. Genetic characterisation of SCC will likely become an important tool to help distinguish low and high-risk cSCC with an increased potential to metastasise in the near future. Available treatments for high-risk and advanced cSCC include surgery, radiotherapy, chemotherapy and targeted therapy with epidermal growth factor receptors inhibitors. Anti-PD-1 antibodies show promising results with response rates of up to 50% in both locally advanced and metastatic cSCC but, in its present form, is not suitable for OTR. Show less

Show moreAfter surgery, around 35% of patients experience problems of excessive scarring, causing disfiguring and impaired function. An incision placed in the wrong direction causes unnecessary skin tension on the wound, resulting in increased collagen disposition and potentially hypertrophic scars. Currently, skin tension lines are used for incision planning. However, these lines are not universal and are a static representation of the skin tension that is in fact under influence of muscle action. By designing a new skin force measurement device the authors intend to make research on dynamic skin characteristics possible and to objectify incision planning and excision closure planning. The device applies a known compressive force to the skin in standardized directions and measures the displacement of the skin. This allows users to measure the skin reaction force in response to compression and to determine the optimal incision line or best wound closure direction. The device has an accuracy of 96% and a sensitivity of < 0.01 mm. It is compact, works non-invasively and standardizes measurement directions and is therefore an improvement over previously designed skin tensiometers. Show less

Show moreTrichoblastomas are rare dermal neoplasms usually found on the scalp and face. Histology shows a proliferation of small basaloid cells arranged in cords or fields surrounded by cellular stroma. Trichoblastomas are usually not aggressive, but trichoblastic carcinomas arising from preexisting trichoblastomas have been described and have been linked to basal cell carcinoma. We found a tumor with features of trichoblastoma with presence of Merkel cells, but with a deeply infiltrative growth pattern into the fat and muscle tissue, without significant architectural or cellular atypia. Tumors with similar growth patterns were previously described as deeply invasive trichoblastic neoplasms. It appears to be a new entity that has been described before but has not been fully characterized: low-grade trichoblastic carcinoma. This malignancy seems to show only locally aggressive growth. Radical excision was accomplished with Mohs micrographic surgery. Show less

Show moreBackground: The use of sutures remains the first choice for wound closure. However, incorrect use of a suture technique can lead to impaired healing. Many techniques are described for high-tension wounds, but not much is known about their mechanical properties. Complications of excessive tension include dehiscence, infection, and ischemic necrosis and could be prevented. This study aimed to compare forces in five techniques (single, horizontal mattress, vertical mattress, pulley, and modified pulley suture) in a standardized wound tension model.Materials and methods: A standardized neoprene wound model was developed on the ForceTRAP system (MediShield B.V., Delft, The Netherlands) to mimic a 5 Newton (N) wound. Five different suture techniques were each repeated 10 times by a student, resident dermatology, and dermsurgeon. The pulling force of the suture's first throw was measured with the Hook-in-Force sensor (Technical University Delft, The Netherlands). Changes in wound tension were measured by the ForceTRAP system. The ForceTRAP is a platform measuring forces from 0 to 20 N in three dimensions with an accuracy of 0.1 N. The Hook-in-Force is a force sensor measuring 0-15 N with an accuracy of 0.5 N. Maximum and mean forces were calculated for each suture technique and operator.Results: Mean maximum pulling force: 5.69 N (standard deviation [SD], 0.88) single, 7.25 N (SD, 1.33) vertical mattress, 8.11 N (SD, 1.00) horizontal mattress, 3.46 N (SD, 0.61) pulley, and 4.52 N (SD, 0.67) modified pulley suture. The mean force increase on the skin (substitute) ranged between 0.80 N (pulley) and 0.96 N (vertical mattress).Conclusions: The pulley suture requires less pulling force compared with other techniques. The mechanical properties of sutures should be taken in consideration when choosing a technique to close wounds. (C) 2020 The Authors. Published by Elsevier Inc. Show less

Show moreThe treatment of choice for cutaneous squamous cell carcinoma is complete surgical excision. Incomplete excision of cutaneous squamous cell carcinoma has an increased risk of local recurrence, deep subclinical progression, and metastasis. This study aimed to investigate the proportion and risk factors of incomplete excised cutaneous squamous cell carcinoma. A systematic review of the literature was performed. Incomplete excision rates for cutaneous squamous cell carcinoma ranged from 0.4% to 35.7%. The pooled incomplete excision risk estimate was 13% (95% confidence interval 9-17%). Risk factors noted in more than one study for incomplete excision included tumor depth and size, type of operator, head and neck localization, and former incomplete excision. We found an overall incomplete excision rate of 13% for cutaneous squamous cell carcinoma. Risk factors should be taken into account in the management of cutaneous squamous cell carcinoma surgical treatment. Show less

Show moreThe risk of cutaneous squamous cell carcinoma (cSCC) is highly increased in organ transplant recipients (OTR) and these tumours carry a major health burden for these patients. This thesis dealt with several aspects of cSCC in OTR. The chapters 2 and 3 review the role of HPV in cSCC and study HPV as a prognostic factor in the aetiology of cSCC. Subsequently, diagnostic factors were studied. In chapter 4 we intended to identify p16 as a possible histopathological marker for cSCC and in chapter 5 we studied the clinical implication of pain as a symptom to differentiate cSCC from other keratinocyte lesions. In chapter 6 we reviewed the literature on metastasis risk in immunocompetent versus OTR population. We studied in chapter 7 in our own population the risk for metastasis, and subsequently risk factors, of cSCC in OTR compared to immunocompetent patients. Show less

Show moreBackground Organ transplant recipients (OTR) have a higher risk of developing cutaneous squamous cell carcinoma (cSCC) compared to the immunocompetent population. Immunosuppression is often stated as a risk factor for metastasis. However, evidence for this is scarce.Objectives To investigate the cSCC metastasis risk in OTR and the immunocompetent population by systematically reviewing the literature.Methods A systematic review of the literature was performed up to January 2018 using: Medline; Embase; Web of Science and ISI Science Citation Index. Studies assessing cSCC metastasis risk in ORT or immunocompetent cohorts were considered. A pooled risk estimate for metastasis was calculated for the immunocompetent population and OTR separately.Results The pooled metastasis risk estimate for OTR was, respectively, 7.3% (95% CI 6.2-8.4) for cSCC on total body, and 11.0% (95% CI 7.7-14.8) for cSCC of the head neck area. For the immunocompetent population reported risk estimate analysis showed a pooled metastatic risk of 3.1% (95% CI 2.8-3.4) in total body cSCC and of 8.5% (95% CI 7.3-9.8) in cSCC of the head and neck area. Pooled risk estimate per single cSCC in OTR was 1.3% (95% CI 1.0-1.7) in total body cSCC and 4.0% (95% CI 2.7-5.5) in cSCC of the head and neck area. In the immunocompetent population, these pooled risk estimates were, respectively, 2.4% (95% CI 2.1-2.6) and 6.7% (95% CI 5.7-7.8).Conclusions Organ transplant recipients show a higher overall risk of cSCC metastasis compared to the immunocompetent population. Metastasis risks per single cSCC were substantially lower in both groups. However, due to heterogeneity and differences between studies, comparisons are difficult. Comprehensive follow-up studies with defined cohorts are necessary to adequately asses the risk for cSCC metastasis. Show less
