Lacerda PN, Lange EP, Luna NM, Miot HA, Abbade LPF. Efficacy of micrographic surgery versus conventional excision in reducing recurrence for basal cell carcinoma and squamous cell carcinoma: A systematic review and meta-analysis. J Eur Acad Dermatol Venereol 2024; 38:1058-1069. [PMID: 38116955 DOI: 10.1111/jdv.19743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/17/2023] [Indexed: 12/21/2023]
Abstract
The standard of care for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) involves excision by conventional surgery (CS) with a predefined safety margin of resection or micrographic surgery (MS) with microscopic margin control. Previous studies have reported the superiority of MS in reducing recurrences for high-risk BCC and SCC. This systematic review aimed to assess MS and CS recurrence rates by including randomized clinical trials (RCTs) and cohort studies. A systematic review and meta-analysis were conducted for related studies in PubMed, LILACS, Embase, Scopus, Web of Science, CINHAL and Cochrane until May 2023. RCTs and cohorts involving patients with BCC or SCC submitted to MS and CS were included. Risk of bias assessment followed Cochrane-recommended tools for RCTs and cohorts, and certainty of evidence followed the GRADE approach. Pooled estimates were used to determine the relative risk (RR) and absolute risk difference (RD) using a random-effects model. Seventeen studies were included, two RCTs and fifteen cohorts. There were 82 recurrences in 3050 tumours submitted to MS, with an overall recurrence rate of 3.1% (95% CI 2.0%-4.7%). For CS, there were 209 recurrences in 3453 tumours, with a recurrence rate of 5.3% (95% CI 2.9%-9.3%). The combined estimate of RR was 0.48 (95% CI 0.36-0.63), without heterogeneity nor evidence of publication bias (p > 0.3). The RD resulted in 2.9% (95% CI 1.0%-4.9%; NNT = 35). Regarding subgroup analysis, the RR for BBC was 0.37 (95% CI 0.25-0.54), and RD was 3.7% (95% CI 0.8%-6.5%; NNT = 28). For SCC, RR was 0.57 (95% CI 0.29-1.13), and RD was 1.9% (95% CI 0.8%-4.7%; NNT = 53). Among primary tumours, RR was 0.39 (95% CI 0.28-0.54), and for recurrent tumours was 0.67 (95% CI 0.30-1.50). There is moderate evidence based on two RCTs, and low evidence based on 15 cohort studies that MS is superior to CS in reducing recurrences of BCCs and primary tumours. The development of protocols that maximize the cost-effectiveness of each method in different clinical scenarios is paramount.

[PMID: 38395222 DOI: 10.1016/j.ad.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 12/29/2023] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
Paraffin-embedded margin-controlled Mohs micrographic surgery (PMMS) includes various procedures such as slow Mohs or deferred Mohs technique, the Muffin and Tübingen techniques, and staged margin excision, or the spaghetti technique. PMMS is a variation of conventional Mohs micrographic surgery (MMS) that allows histopathological examination with delayed margin control. PMMS requires minimum training and may be adopted by any hospital. The setback is that PMMS can require procedures across multiple days. PMMS lowers the rate of recurrence of basal cell carcinoma vs wide local excision in high-risk basal cell carcinoma, and improves the rates of recurrence and survival in lentigo maligna. PMMS can be very useful in high-risk squamous cell carcinoma treatment. Finally, it is a promising technique to treat infrequent skin neoplasms, such as dermatofibrosarcoma protuberans, or extramammary Paget's disease, among others. In this article, we present a literature narrative review on PMMS, describing techniques and indications, and highlighting long-term outcomes.

Assessment of Standard Surgical Excision Efficacy and Analysis of Recurrence-Associated Factors in 343 Cases of Nasal Basal Cell Carcinoma: A Single-Center Retrospective Study. Healthcare (Basel) 2024; 12:513. [PMID: 38470624 PMCID: PMC10931200 DOI: 10.3390/healthcare12050513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 02/04/2024] [Accepted: 02/10/2024] [Indexed: 03/14/2024] Open
Abstract
In Caucasians, basal cell carcinoma, the predominant non-melanoma skin cancer type, poses challenges for surgeons due to anatomical and aesthetic concerns, particularly when located on the nose. The study aimed to evaluate tumor distribution, size, morphological subtypes, surgical outcomes, radicality levels, and their correlation with recurrence rates. A retrospective analysis encompassed 343 cases of nasal skin cancer over a four-year period from 1 January 2019 to 31 December 2022. The research cohort comprised 252 female and 91 male participants, averaging 75.2 years old. Tumors were most found on the left sidewall of the nose (25.4%) and the dorsum (24.8%). The infiltrative morphological subtype was predominant (70.8%). Standard surgical excision with fasciocutaneous plastic was the preferred surgical procedure. Radical excision, defined by the absence of tumor cells in a resection margin, was accomplished in 79.0% of lesions, whereas 16.9% demonstrated incomplete excision, signifying the presence of tumor cells in the resection margin. Non-radically excised tumors exhibited a significantly higher recurrence rate (24.1%) compared to those with radical excision (6.3%). In nasal reconstruction, diverse surgical techniques are essential for precise adaptation based on factors like tumor characteristics and patient needs. Despite surgeons' careful adherence to excision margin guidelines, the possibility of non-radical outcome cannot be eliminated.

Abstract
Basal cell carcinoma (BCC) is the most common malignant tumour in white populations. Multidisciplinary experts from European Association of Dermato-Oncology (EADO), European Dermatology Forum, European Society for Radiotherapy and Oncology (ESTRO), Union Européenne des Médecins Spécialistes, and the European Academy of Dermatology and Venereology developed updated recommendations on diagnosis and treatment of BCC. BCCs were categorised into 'easy-to-treat' (common) and 'difficult-to-treat' according to the new EADO clinical classification. Diagnosis is based on clinico-dermatoscopic features, although histopathological confirmation is mandatory in equivocal lesions. The first-line treatment of BCC is complete surgery. Micrographically controlled surgery shall be offered in high-risk and recurrent BCC, and BCC located on critical anatomical sites. Topical therapies and destructive approaches can be considered in patients with low-risk superficial BCC. Photodynamic therapy is an effective treatment for superficial and low-risk nodular BCCs. Management of 'difficult-to-treat' BCCs should be discussed by a multidisciplinary tumour board. Hedgehog inhibitors (HHIs), vismodegib or sonidegib, should be offered to patients with locally advanced and metastatic BCC. Immunotherapy with anti-PD1 antibodies (cemiplimab) is a second-line treatment in patients with a progression of disease, contraindication, or intolerance to HHI therapy. Radiotherapy represents a valid alternative in patients who are not candidates for or decline surgery, especially elderly patients. Electrochemotherapy may be offered when surgery or radiotherapy is contraindicated. In Gorlin patients, regular skin examinations are required to diagnose and treat BCCs at an early stage. Long-term follow-up is recommended in patients with high-risk BCC, multiple BCCs, and Gorlin syndrome.

Abstract
Imaging across different scales is essential for understanding healthy organ morphology and pathophysiological changes. The macro- and microscale three-dimensional morphology of large samples, including intact human organs, is possible with X-ray microtomography (using laboratory or synchrotron sources). Preparation of large samples for high-resolution imaging, however, is challenging due to limitations such as sample shrinkage, insufficient contrast, movement of the sample and bubble formation during mounting or scanning. Here, we describe the preparation, stabilization, dehydration and mounting of large soft-tissue samples for X-ray microtomography. We detail the protocol applied to whole human organs and hierarchical phase-contrast tomography at the European Synchrotron Radiation Facility, yet it is applicable to a range of biological samples, including complete organisms. The protocol enhances the contrast when using X-ray imaging, while preventing sample motion during the scan, even with different sample orientations. Bubbles trapped during mounting and those formed during scanning (in the case of synchrotron X-ray imaging) are mitigated by multiple degassing steps. The sample preparation is also compatible with magnetic resonance imaging, computed tomography and histological observation. The sample preparation and mounting require 24-36 d for a large organ such as a whole human brain or heart. The preparation time varies depending on the composition, size and fragility of the tissue. Use of the protocol enables scanning of intact organs with a diameter of 150 mm with a local voxel size of 1 μm. The protocol requires users with expertise in handling human or animal organs, laboratory operation and X-ray imaging.

Risk analysis of systemic side effects of tumescent local anaesthesia in the surgical treatment of geriatric and multimorbid patients with skin cancer. J Eur Acad Dermatol Venereol 2023; 37:65-74. [PMID: 36152007 DOI: 10.1111/jdv.18588] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 08/17/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Due to demographic change and increased UV exposure, the number of dermatosurgical procedures in the elderly is increasing. Data on the occurrence of systemic side effects during and after treatment with tumescent local anaesthesia are limited and do not refer to details such as volume and composition of local anaesthetics or epinephrine additive. OBJECTIVES The aim of this study was to investigate the risk of systemic side effects in elderly patients undergoing skin tumour surgery with tumescent local anaesthesia. METHODS Investigation of systemic complications in patients (≥75 years) who underwent head and neck skin tumour surgery under tumescent local anaesthesia at the Department of Dermatology, University Medical Centre Tübingen, between October 2018 and March 2020. RESULTS In total 782 patients (479 males, 303 females) with a mean age of 83.3 years (range: 75.1-102.2 years) could be included. A total of 2940 procedures were performed. Patients were assigned to two groups. The old-old group (≥75-84 years) included 491 patients and the oldest-old group (≥85 years) included 291 patients. The total inpatient stay and thus mean follow-up period was 4.9 days (range 1-28 days). 92.0% (719/782) suffered from pre-existing comorbidities. Systemic complications occurred in 10.2% (80/782; old-olds: 8.6%, oldest-olds: 13.1%). Hypertensive crisis (>180/120 mmHg) requiring intervention (6.7%) that occurred intraoperatively or during the inpatient stay was the most frequent systemic complication. Cardiac arrhythmias occurred postoperatively in 0.8% of cases. No life-threatening complications directly related to tumescent local anaesthesia were found. CONCLUSIONS Skin tumour surgery in tumescent local anaesthesia for the elderly is safe, and complications caused by general anaesthesia can be avoided. Systemic complications can occur, but are usually mild, are caused by pre-existing diseases and perioperative excitement, and can be rapidly detected and well treated by monitoring. There is no direct correlation of complications to high-tumescent concentrations or volume quantities.

Abstract
Histopathology is the gold standard for disease diagnosis. The use of digital histology on fresh samples can reduce processing time and potential image artifacts, as label-free samples do not need to be fixed nor stained. This fact allows for a faster diagnosis, increasing the speed of the process and the impact on patient prognosis. This work proposes, implements, and validates a novel digital diagnosis procedure of fresh label-free histological samples. The procedure is based on advanced phase-imaging microscopy parameters and artificial intelligence. Fresh human histological samples of healthy and tumoral liver, kidney, ganglion, testicle and brain were collected and imaged with phase-imaging microscopy. Advanced phase parameters were calculated from the images. The statistical significance of each parameter for each tissue type was evaluated at different magnifications of 10×, 20× and 40×. Several classification algorithms based on artificial intelligence were applied and evaluated. Artificial Neural Network and Decision Tree approaches provided the best general sensibility and specificity results, with values over 90% for the majority of biological tissues at some magnifications. These results show the potential to provide a label-free automatic significant diagnosis of fresh histological samples with advanced parameters of phase-imaging microscopy. This approach can complement the present clinical procedures.

Abstract
INTRODUCTION Cutaneous squamous cell carcinoma (cSCC) is a common tumor of elderly Caucasian patients. METHODS Competing multivariable risk models to analyze different types of cSCC associated death (local infiltration [LI], locoregional [LR], and distant metastases [DM]) in terms of prognostic factors. RESULTS AND DISCUSSION 1400 patients were analyzed. In the adjusted multivariable subdistribution hazard approach for tumor volume, the best model for death of cSCC overall revealed the presence of desmoplasia (HR 4.52; p < 0.001), bone invasion (HR 10.06; p < 0.01), and immunosuppression (HR 3.19; p = 0.003) as significant factors. Death due to LI indicated desmoplasia (HR 15.39; p < 0.01) and bone invasion (HR 16.9; p < 0.001) as significant factors. For death by LM, immunosuppression with a HR of 3.27; p = 0.004 was the only significant prognostic factors as well as in death by DM with a HR of 4.54; p = 0.02. CONCLUSIONS The three types of death caused by cSCC can be distinguished based on risk factors with different weights. Patients with these factors should be monitored closely.

Abstract
BACKGROUND Basal cell carcinoma (BCC) can cause extensive tissue damage if untreated. Complete surgical excision is the treatment of choice, but especially in the head-and neck area, defining both radical and healthy skin sparing surgical margins is complex. MATERIALS AND METHODS Excised, small (≤ 1 cm), BCCs of the head and neck were retrospectively analyzed, comparing histological properness of surgical margins after clinical-dermatoscopical preoperative evaluation (cases), vs. clinical evaluation only (controls) and recurrences. RESULTS Of 281 BCCs: 6 % (8/139) of cases and 8 % (12/142) of controls had unproper deep margins; 4 % (5/139) of cases, 20 % (29/142) of controls had unproper lateral margins (P < 0.001). Surgical 3 mm lateral margins were unproper in 0 % (15/66) of cases, 15 % (10/66) of controls (P > 0.005); surgical 1-2 mm lateral margins were unproper in 7 % (5/73) of cases, 25 % (19/76) of controls (P < 0.01). Of cases excised at 3 mm, 1-2 mm, and controls, 1.5 %, 0 %, and 7.7 % recurred, respectively. CONCLUSIONS BCC excision at 3 mm may be appropriate in the head and neck for small, dermatoscopically well-defined and non-aggressive BCCs, attaining surgical cure rates of 100 % and 1.5 % recurrences. Excision at 1-2 mm should be reserved only for BCCs in very difficult-to-treat areas, as the surgical cure rate was only 93 %.

Dermatoskopisch kontrollierte, schmalere Resektionsränder bei Basalzellkarzinomen an Kopf und Hals: Retrospektive Fallkontrollstudie. J Dtsch Dermatol Ges 2022; 20:807-817.

Abstract
Hintergrund: Unbehandelt kann das Basalzellkarzinom (BCC) erhebliche Gewebezerstörungen verursachen. Die komplette chirurgische Exzision ist die Behandlung der Wahl. Allerdings stellt es besonders im Gesichts- und Halsbereich eine Herausforderung dar, den Tumor vollständig zu entfernen und möglichst viel gesundes Gewebe zu erhalten. Material und Methoden: Bereits exzidierte kleine BCC (≤ 1 cm) von Kopf oder Hals wurden retrospektiv analysiert. Verglichen wurde die histologisch kontrolliert angemessene Breite des Resektionsrandes nach präoperativer dermatoskopischer Untersuchung (Fälle) im Vergleich zur rein klinischen Untersuchung (Kontrollen), sowie die Rezidivrate. Ergebnisse: Bei 281 BCC: 6 % (8/139) der Fälle und 8 % (12/142) der Kontrollen zeigten inadäquate basale Resektionsränder; 4 % (5/139) der Fälle und 20 % (29/142) der Kontrollen zeigten inadäquate laterale Resektionsränder (P < 0.001). Laterale Resektionsränder von 3 mm waren in 0 % (15/66) der Fälle, jedoch in 15 % (10/66) der Kontrollen inadäquat (P >0.005); laterale Resektionsränder von 1-2 mm waren in 7 % (5/73) der Fälle und in 25 % (19/76) der Kontrollen inadäquat (P < 0.01). Rezidive traten in den Fällen mit 3 mm Resektionsrand in 1,5 % auf, in den Fällen mit 1-2 mm Resektionsrand bei 0 %, und bei den Kontrollen bei 7,7 %. Schlussfolgerung: Für BCC im Kopf- und Halsbereich erscheint ein Resektionsrand von 3 mm angemessen, sofern das BCC klein, dermatoskopisch gut definiert und wenig aggressiv ist. Hier zeigten sich operative Heilungsraten von 100 % mit 1,5 % Rezidiven. Resektionsränder von 1-2 mm sollten nur für BCC in sehr schwierig zu behandelnden Bereichen in Betracht gezogen werden, da die Heilungsrate hier nur bei 93 % lag.

J Eur Acad Dermatol Venereol 2022; 36:1178-1190. [PMID: 35274381 DOI: 10.1111/jdv.18048] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 02/15/2022] [Indexed: 11/29/2022]
Abstract
In high-risk basal cell carcinomas (BCCs), micrographic surgery (MS) has high tissue preservation and low recurrence rates. The Mohs technique is the most commonly used technique, with limited use of other MS techniques. No studies have been designed to compare the MS methods. This review aimed to assess BCC recurrence rates of different MS techniques. A systematic review and meta-analysis was conducted to search for related studies in PubMed, LILACS, EMBASE, SCOPUS, WEB OF SCIENCE, CINHAL, and COCHRANE until March 2021. Randomized clinical trials (RCTs) and observational studies involving patients with BCC and indications for different MS techniques were included. Study selection and data extraction were performed independently by three peer reviewers, as was the risk of bias assessment using the Joanna Briggs Institute tool. Pooled estimates were assessed using the random-effects model (Logit), and heterogeneity was assessed by the chi-square test (χ2 ). Stata Software version 17.0 was used for analysis. Eighteen studies were included, 2 RCTs and 16 observational studies. The overall recurrence rate was 2% (95% CI, 1.0-3.0%; χ2 = 46.2; p = 0.00; 18 studies, 10,424 BCCs). In studies using the Mohs technique, the recurrence rate was 3.0% (95% CI, 1.0-5.0%; χ2 = 11.0; p = 0.00; 6 studies; 1,582 BCCs), with the Munich technique 3.0% (95% CI, 2.0-5.0%; χ2 = 0.0; no heterogeneity; 3 studies; 404 BCCs), with Tubingen technique 1% (95% CI, 1.0-2.0%; χ2 = 12.1; p = 0.00; 8 studies; 8,374 BCCs) and with the Muffin technique 0.0% (95% CI, 0.0-6.0%; 1 study; 64 BCCs). Relapse rates between MS techniques were low and appeared to be similar. However, the design of this review and the absence of primary studies that directly compare the techniques do not allow us to assert the superiority between them.
