Multicenter Retrospective Andalusian Study of the Use of Sonidegib for the Treatment of Local Advanced Basal Cell Carcinoma in Real Clinical Practice.

INTRODUCTION: Locally advanced basal cell carcinoma (LA-BCC) is defined as that BCC in which there is radiological confirmation of invasion of certain neighboring structures in depth and also, usually, a BCC that is of a sufficient size and invasion (although there is no radiological demonstration of deep invasion) in which surgery and radiotherapy are not adequate, are insufficient or are contraindicated to achieve the cure of the tumor, either due to characteristics of the tumor itself or of the patient. Sonidegib is indicated for the treatment of adult patients with locally advanced basal cell carcinoma that is not amenable to curative surgery or radiotherapy. MATERIAL AND METHODS: This is a retrospective, multicenter and descriptive study in nine centers in Andalusia, Spain. Patients treated with sonidegib for >3 months for locally advanced BCC were included from 1 January 2021 to 1 January 2023. Epidemiological, efficacy and safety data were collected. RESULTS: In the present study, a total of 38 patients were included, with a median age of 76.23 years (range 40-101). Prior treatment was surgery (31.57%; n = 25), radiotherapy (15.78%; n = 6), vismodegib (31.57%; n = 12). Eleven patients had not received prior treatment. LA-BCC were located in the cephalic pole, face or scalp. There was a total response in 9/38 patients (23.7%), partial response in 25/38 patients (65.8%) and no response in 4 patients (10.52%). In 6/34 patients, the dose was reduced to 200 mg every other day until it was discontinued due to adverse effects. The main adverse effects reported were dysgeusia (n = 8), asthenia (n = 8), = 6), muscle spasms (n = 6), alopecia (n = 4) and gastrointestinal intolerance (n = 4). DISCUSSION: Sonidegib is the second iHh authorized for the treatment of adult patients with locally advanced BCC who are not amenable to curative surgery or radiotherapy, based on the results of the phase II clinical trial, BOLT. Sonidegib shows good effectiveness and an acceptable safety profile in routine clinical practice in the sample presented.

Surgery for Cutaneous Squamous Cell Carcinoma and its Limits in Advanced Disease.

Surgery remains the first-line therapeutic option for most patients with cutaneous squamous cell carcinoma (cSCC). However, in the current therapeutic landscape, surgery must attempt to the complete tumor resection (R0 resection) with the lowest risk of surgical complications. This double aim is usually accomplished through standard excision with clinical margins in patients with low-risk tumors or by some of the micrographically controlled surgery procedures for patients with tumors at high-risk of local recurrence and metastasis. Surgery is also a first-line treatment for nodal metastases of cSCC as well as an option to consider in patients who develop recurrences while receiving immunotherapy, or as a palliation procedure in patients with advanced tumors. Neoadjuvant immunotherapy, that is the use of a medical treatment before surgery, is under investigation in patients with cSCC. The decision-making process and guidelines recommendations regarding cSCC surgery are reviewed in this manuscript.

Increasing Frequency of Seborrheic Keratosis Diagnoses as a Favorable Consequence of Teledermatology-Based Skin Cancer Screening: A Cross-sectional Study of 34,553 Patients.

BACKGROUND: Screening of skin cancer by teledermatology (TD) has improved the early detection of skin cancer by enhancing access to skin cancer clinics. OBJECTIVE: We sought to analyze how TD-based skin cancer screening has changed the frequency of consultations for benign lesions. PATIENTS AND METHODS: A cross-sectional study including teleconsultations received during a 7-year period was conducted to analyze and compare the trendlines of each lesion type over the study period. Trendlines were analyzed using a linear regression model with the R-squared (R 2) test for goodness of fit. RESULTS: A total of 34,553 teleconsultations were included in the study. Seborrheic keratoses, followed by benign melanocytic lesions, were the most frequent lesions diagnosed. The pick-up rate for malignant lesions was 1:8.6 teleconsultations. Seborrheic keratoses and precancerous lesions showed a positive trendline with good fit to the linear model (R 2 = 0.8 and R 2 = 0.8, respectively). Tis-T1 malignant melanoma (in situ melanoma or melanoma with a Breslow thickness <1 mm) showed an increasing trendline with moderate-to-low fit to the model (R 2 = 0.4). CONCLUSIONS: TD-based screening of skin cancer is associated with an increasing rate of consultations involving seborrheic keratoses, which can be considered a consequence of improved access to dermatologists resulting from TD implementation.

Internet-based skin cancer screening using clinical images alone or in conjunction with dermoscopic images: A randomized teledermoscopy trial.

BACKGROUND: Teledermoscopy involves the use of dermoscopic images for remote consultation and decision-making in skin cancer screening. OBJECTIVE: We sought to analyze the potential benefits gained from the addition of dermoscopic images to an internet-based skin cancer screening system. METHODS: A randomized clinical trial assessed the diagnostic performance and cost-effectiveness of clinical teleconsultations (CTC) and clinical with dermoscopic teleconsultations. RESULTS: A total of 454 patients were enrolled in the trial (nCTC = 226, nclinical with dermoscopic teleconsultation = 228). Teledermoscopy improved sensitivity and specificity (92.86% and 96.24%, respectively) compared with CTC (86.57% and 72.33%, respectively). Correct decisions were made in 94.30% of patients through clinical with dermoscopic teleconsultations and in 79.20% in CTC (P < .001). The only variable associated with an increased likelihood of correct diagnosis was management using teledermoscopy (odds ratio 4.04; 95% confidence interval 2.02-8.09; P < .0001). The cost-effectiveness analysis showed teledermoscopy as the dominant strategy, with a lower cost-effectiveness ratio (65.13 vs 80.84). LIMITATIONS: Potentially, a limitation is the establishment of an experienced dermatologist as the gold standard for the in-person evaluation. CONCLUSIONS: The addition of dermoscopic images significantly improves the results of an internet-based skin cancer screening system, compared with screening systems based on clinical images alone.

Effect of teledermatology on the prognosis of patients with cutaneous melanoma.

OBJECTIVE: To evaluate differences in the initial prognosis of patients with cutaneous melanoma managed by teledermatology (TD) vs other non-TD referral systems. DESIGN: Descriptive and longitudinal study of a store-and-forward TD system aimed at the triage of patients with suspicious pigmented lesions. SETTING: In 2003, a store-and-forward TD triage system aimed at the selection of patients with skin growths suggestive of cancer was implemented at a skin cancer clinic. This system has been shown to be accurate and reliable and able to significantly shorten waiting periods for consultation with a dermatologist. PARTICIPANTS: Patients with primary cutaneous melanoma referred to the Melanoma Clinic of the Dermatology Unit, Hospital Universitario Virgen Macarena, Seville, Spain, by TD or non-TD tracks were included in the study. MAIN OUTCOME MEASURES: Decisions on the referral of patients with suspicious skin lesions by store-and-forward TD vs by a conventional referral system. Breslow thickness and tumor stage were recorded in each study group (TD and non-TD) and were compared. RESULTS: Two hundred one patients with primary cutaneous melanoma were enrolled in the study. In total, 33.3% were managed at their primary care center by teleconsultation, whereas 66.7% were managed by a conventional referral system. The mean Breslow thickness was significantly lower among patients in the TD group than among patients in the non-TD group (1.06 vs 1.64 mm, P = .03). The frequency of melanoma with a favorable initial prognosis (tumor stages Tis and T1a) was significantly higher in the TD group (70.1% vs 56.9%, P = .03). The odds ratio of having a cutaneous melanoma with a favorable initial prognosis in the TD group was 1.96 (95% CI, 1.14-3.50; P = .04). CONCLUSION: Teledermatology as a screening system for cutaneous melanoma has a favorable effect on the initial prognosis of patients with melanoma.

Economic evaluation of a store-and-forward teledermatology system for skin cancer patients.

We conducted an economic analysis of a store-and-forward teledermatology system for the routine triage of skin cancer patients. A cost-identification, cost-effectiveness and sensitivity analysis under a societal perspective was used to compare teledermatology with the conventional care alternative. In the period March 2004 to July 2005, a total of 2009 teledermatology referrals were managed from 12 Primary Care Centres (PCCs) of the public health system. The unit cost was of Euro 79.78 per patient in teledermatology, and Euro 129.37 per patient in conventional care (P < 0.005), with an incremental cost of Euro 49.59 per patient in favour of teledermatology. The cost ratio between teledermatology and conventional care was 1.6. There was a significant inverse relation between the unit cost in each participating PCC and the number of teleconsultations transmitted from them (P < 0.001). Teledermatology resulted in a more cost-effective, or dominant, methodology. In a public health system equipped with an intranet, the routine use of teledermatology in skin cancer clinics is a cost-effective method of managing referrals.
