Objective: Patients undergoing Mohs Micrographic Surgery (MMS) for facial non-melanoma skin cancer (NMSC) experience appearance-related psychosocial distress due to its post-surgical esthetic changes. However, little is known about its development over a longer follow-up period. This study prospectively assessed appearance-related psychosocial distress in patients undergoing MMS for facial NMSC over a 1-year follow up period., Methods: Patients who had MMS for facial NMSC between September 2020 and October 2021 were invited to answer the FACE-Q Skin Cancer - appearance-related psychosocial distress scale preoperatively, 2 weeks, 6 months, and 1 year after surgery., Results: A total of 217 patients completed the questionnaire at baseline. In addition, 158 (72.8%), 139 (64.1%), and 120 (55.3%) questionnaires were successfully answered 2 weeks, 6 months, and 1 year after surgery, respectively. Patients with a peripheral lesion presented higher appearance-related psychosocial distress scores at baseline than patients with a central lesion (p = 0.02). There was a decreasing trend in appearance-related psychosocial distress over time, but without a significant result (baseline-2-week; p = 0.73, 2-week-6-month; p = 0.80, 6-month-1-year; p = 0.17, baseline-1-year; p = 0.23). Patients with secondary intention healing and graft reconstruction methods experienced more appearance-related psychosocial distress over time than patients with primary wound closures (p = 0.03)., Conclusions: Patients still experience appearance-related psychosocial distress 1 year after MMS. These patients may benefit from targeted counseling. Additionally, predictors of more appearance-related psychosocial distress, such as secondary intention healing and graft reconstruction methods, may benefit from additional psychological care., (© 2023 John Wiley & Sons Ltd.)

Background: Punch biopsy is the gold standard for diagnosis and subtyping of basal cell carcinoma. The aim of this study was to assess whether use of optical coherence tomography (OCT), a non-invasive imaging tool, might avoid the need for biopsy., Methods: In a multicentre, randomised, non-inferiority trial, patients (aged ≥18 years) with an indication for biopsy of a suspected basal cell carcinoma outside the H-zone (high-risk zone) of the face were randomly assigned (1:1) to receive either OCT or punch biopsy (regular care) via a web-based randomisation system. Patients were enrolled from three participating centres in the Netherlands: Maastricht University Medical Centre+, Catharina Hospital Eindhoven, and Zuyderland Medical Centre Heerlen. Stratification factors for randomisation were participating centre and the grade of clinical basal cell carcinoma suspicion (high vs low). The primary endpoint was the proportion of patients free from a recurrent or residual lesion (malignant or premalignant) 12 months after treatment. Modified intention-to-treat and per-protocol analyses were conducted, with a predefined non-inferiority margin of -10%. This trial is registered with ClinicalTrials.gov number, NCT03848078, and is complete., Findings: Between Feb 25, 2019, and Sept 2, 2020, 598 patients were enrolled and randomly assigned to either the regular care group (n=299) or the OCT group (n=299). Data on the primary endpoint were available in 553 patients (n=268 in the regular care group, n=285 in the OCT group). After median follow-up of 12·7 months (IQR 11·2-14·1) in the OCT group and 12·6 months (10·8-14·3) in the regular care group, 253 (94%) of 268 patients in the OCT group and 266 (93%) of 285 patients in the regular care group were free from recurrent or residual lesions (malignant or pre-malignant) 12 months after treatment. According to our modified intention-to-treat analysis, the absolute difference (OCT vs regular care) was 1·07% (95% CI -2·93 to 5·06; one-sided p=0·30), with the lower limit of the 95% CI not exceeding the predefined non-inferiority margin of -10%. Per-protocol analyses led to proportions free from a residual or recurrent lesion (premalignant or malignant) of 95% (250 of 263) in the OCT group and 94% (262 of 278) in the regular care group, and an absolute difference of 0·81% (95% CI -2·98 to 4·60; one-sided p=0·34)., Interpretation: OCT-guided diagnosis and treatment of basal cell carcinoma is non-inferior to regular care punch biopsy. Implementation of OCT for diagnosis of basal cell carcinoma could reduce the number of consultations and invasive procedures., Funding: The Netherlands Organization for Health Research and Development and Maurits en Anna de Kock Stichting., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2022 Elsevier Ltd.

Objective: Nonmelanoma skin cancer (NMSC) is one of the most diagnosed cancers in the world, with the number of new occurrences rising every year. Most patients with facial skin cancer experience cancer-related worry. Yet, little is known about their worry during the period after cancer treatment. This study aimed to assess the long-term change of cancer worry after surgical treatment in patients with NMSC., Methods: Patients undergoing surgery for facial NMSC between December 2017 and March 2020 were asked to complete the FACE-Q Skin Cancer-Cancer Worry scale before (baseline), 3-month, and 1-year post-surgery., Results: A total of 151 patients completed the baseline and 3-month, and 99 (65.6%) the 1-year post-operative survey. A significant decrease in cancer worry score was seen between baseline and 3-month post-surgery (p < 0.001). No difference was found between the 3-month and 1-year post-surgery scores (p = 0.78). Less improvement in cancer worry was seen for patients who had one facial skin cancer in their medical history (p = 0.001) and patients who had a history of facial surgery (p < 0.001)., Conclusion: Post-surgery patients still experience cancer worry. Therefore, targeted counseling might be of value when coping with cancer-related concerns. Patients with a history of facial NMSC and patients with a history of facial surgery might benefit from additional counseling., (© 2022 John Wiley & Sons Ltd.)

Background: Nonsteroidal anti-inflammatory drugs and vitamin-D derivatives can target signaling pathways activated in basal cell carcinoma (BCC)., Objective: We investigated the efficacy of topically applied diclofenac sodium 3% gel, calcitriol 3 μg/g ointment, and a combination of both in superficial BCC (sBCC) and nodular BCC., Methods: Patients with a primary, histologically proven sBCC (n = 64) or nodular BCC (n = 64) were randomized to topical diclofenac, calcitriol, combination of both, or no topical treatment (control group). After self-application twice daily under occlusion (8 weeks), tumors were excised. Primary outcome was posttreatment expression levels of proliferation (Ki-67) and antiapoptosis (B-cell lymphoma [Bcl-2]) immunohistochemical markers. Secondary outcomes were histologic clearance, adverse events, application-site reactions, and patient compliance., Results: sBCC treated with diclofenac showed a significant decrease in Ki-67 (P < .001) and Bcl-2 (P = .001), and after combination therapy for Ki-67 (P = .012). Complete histologic tumor regression was seen in 64.3% (P = .0003) of sBCC (diclofenac) and 43.8% (P = .007) of sBCC (combination therapy) compared with 0.0% of controls. No significant changes were found in nodular BCC. Application-site reactions were mostly mild to moderate., Limitations: The sample size was small., Conclusion: Our results suggest that topical diclofenac is a promising new treatment for sBCC. Its mode of action differs from available noninvasive therapies, and thus has an additive value., (Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Background: Basal cell carcinoma (BCC) is the most common cancer in Caucasians. Trichoepithelioma (TE) is a benign neoplasm that strongly resembles BCC. Both are hair follicle (HF) tumours. HFs are hypoxic microenvironments, therefore we hypothesized that hypoxia-induced signalling pathways could be involved in BCC and TE as they are in other human malignancies. Hypoxia-inducible factor 1 (HIF1) and mechanistic/mammalian target of rapamycin (mTOR) are key players in these pathways., Objectives: To determine whether HIF1/mTOR signalling is involved in BCC and TE., Methods: We used immunohistochemical staining of formalin-fixed paraffin-embedded BCC (n = 45) and TE (n = 35) samples to assess activity of HIF1, mTORC1 and their most important target genes. The percentage positive tumour cells was assessed manually in a semi-quantitative manner and categorized (0%, <30%, 30-80% and >80%)., Results: Among 45 BCC and 35 TE examined, expression levels were respectively 81% and 57% (BNIP3), 73% and 75% (CAIX), 79% and 86% (GLUT1), 50% and 19% (HIF1α), 89% and 88% (pAKT), 55% and 61% (pS6), 15% and 25% (pMTOR), 44% and 63% (PHD2) and 44% and 49% (VEGF-A). CAIX, Glut1 and PHD2 expression levels were significantly higher in TE when only samples with at least 80% expression were included., Conclusions: HIF and mTORC1 signalling seems active in both BCC and TE. There are no appreciable differences between the two with respect to pathway activity. At this moment immunohistochemical analyses of HIF, mTORC1 and their target genes does not provide a reliable diagnostic tool for the discrimination of BCC and TE.
