["PLASTICS" DURING THE WAR OF "IRON SWORDS" - THE ROLE OF A SPECIALIST IN PLASTIC AESTHETIC AND RECONSTRUCTIVE SURGERY].

INTRODUCTION: A war usually requires a new or adjusted set up and needs of all caregivers according to the "new" status. The current war in Israel began on the 7.10.2023. The Israeli Ministries of Defense and Health were in a new status in which they had to complete new requirements according to the use of new weapons, and in numbers and types of injuries that overwhelmed the system from the day the war began. In the past, we published evidence that in times of terror, as in times of war, epidemiology of injuries changes and requires adjustments in human resources, surgical tools and consumables in the Israeli health and defense systems. This article aims to describe the role of specialists in plastic, aesthetic and reconstructive surgery and the first response according to the existing system divided into prevention, preparedness, response and rehabilitation. In the long term rapid response, recruitment of human resources, abilities and flexibility of the system enables overcoming a sudden "new" status as in war, terror and mass casualty events.

Bromelain-based enzymatic burn debridement: A systematic review of clinical studies on patient safety, efficacy and long-term outcomes.

In 2012 the European Medicines Agency approved a pineapple stem-derived Bromelain-based debridement concentrate of proteolytic enzymes (NexoBrid®, MediWound Ltd, Yavne, Israel) for adult deep burns. Over 10 000 patients have been successfully treated with NexoBrid® globally, including in the US. The aim of our study is to perform a systematic review of the current literature on Nexobrid® outcomes. We conducted a literature search in PubMed, Google Scholar, Embase, and other search engines (2013-2023). The online screening process was performed by two independent reviewers with the Covidence tool. The protocol was reported using the Preferred Reporting Items for Systematic Review and Meta-Analyses, and it was registered at the International Prospective Register of Systematic Reviews of the National Institute for Health Research. We identified 103 relevant studies of which 34 were found eligible. The included studies report the positive effects of Nexobrid® on burn debridement, functional and cosmetic outcomes, scarring, and quality of life. Also, they validate the high patient satisfaction thanks to enhanced protocols of analgosedation and/or locoregional anaesthesia during Bromelain-based debridement. Two studies investigate potential risks (coagulopathy, burn wound infection) which concluded there is no strong evidence of these adverse events. NexoBrid® is a safe, selective, non-surgical eschar removal treatment modality. The benefits of Bromelain-based debridement are faster debridement and healing times, reduced operations, length of stay, cases of sepsis, blood transfusions, and prevention of compartment syndrome. Existing evidence suggests that the indications and the role of Bromelain-based debridement are expanding to cover "off-label" cases with significant benefits to the global healthcare economy.

Bromelain-based enzymatic debridement of chronic wounds: Results of a multicentre randomized controlled trial.

Chronic wounds are estimated to affect over 6 million people annually in the United States with an estimated annual cost of $25 billion. Debridement represents a key step in their management and is considered a basic necessity to induce the functional process of tissue repair. However, there is an unmet need for an efficient rapid acting non-surgical debridement agent. Bromelain-based enzymatic debridement has been proven to provide an effective, selective and safe non-surgical debridement in deep burns. EscharEx (MediWound Ltd, Yavne, Israel), is a bromelain-based enzymatic debridement agent currently in development for chronic wounds. The aim of this study was to assess its safety and efficacy in chronic wounds. Seventy-three patients suffering from a lower extremity ulcer of diabetic/venous insufficiency/post-surgical/traumatic aetiology were enrolled in a multicentre, assessor blinded, randomized controlled trial. Patients were randomized to topical treatment by either EscharEx or its gel vehicle for up to 10 daily 4 hour applications, and then continued follow-up for up to 6 months. The EscharEx arm achieved a significantly higher incidence of complete debridement compared to the gel vehicle arm; 55 versus 29% (p = .047), thus meeting the primary endpoint of this study. The EscharEx and gel vehicle arms achieved similar reductions in wound area, non-viable tissue area and wound healing scores during the debridement period. There were no significant differences between the arms in the incidence of complete wound closure (41% in the EsxcharEx arm vs. 53% in the gel vehicle arm) and in the mean time to complete wound closure (70.0 ± 32.8 days in the EsxcharEx arm vs. 65.7 ± 38.4 days in gel vehicle arm). There were no significant safety issues and EscharEx demonstrated a favourable benefit to risk profile.

Development of a porcine hard-to-heal wound model: evaluation of a bromelain-based enzymatic debriding agent.

AIMS: We describe the development of a novel porcine eschar model and compare the debridement efficacy of various concentrations of a novel bromelain-based enzymatic agent with collagenase. METHODS: Full thickness excisional wounds were created on pigs and injected intradermally with various doses of doxorubicin. Wounds were monitored for a period of 46 days for the development of eschar and wound closure. After determining the optimal concentration and dose of doxorubicin resulting in non-healing eschars, these conditions were used to create additional wounds on another set of animals. The resulting eschars were treated with various concentrations of a novel bromelain-based enzymatic agent (EscharEx-02) or collagenase. The primary endpoint was greater than 95% removal of the central eschar. RESULTS: Consistent eschars composed of two distinct areas (a central area of exudate and slough representing the hard-to-heal wound bed, and a peripheral area of full-thickness mummified necrosis) were seen after injection of doxorubicin (0.5 ml/cm2 of stock solution 0.75mg/ml) at one and six days after wound creation. Complete removal of the central eschar was achieved in all wounds after five and eight treatments with 5% and 2% EscharEx-02 respectively. Complete removal of the central eschar with collagenase was achieved in 0% and 82% of the wounds after 10 and 16 treatments respectively. CONCLUSIONS: We describe a porcine model for creating eschars similar to hard-to-heal wounds in humans. A novel bromelain-based enzymatic debridement agent was more effective than a commercially available collagenase in removing eschars in this wound model.

Rapid enzymatic burn debridement: A review of the paediatric clinical trial experience.

NexoBrid (NXB) has been proven to be an effective selective enzymatic debridement agent in adults. This manuscript presents the combined clinical trial experience with NXB in children. Hundred and ten children aged 0.5 to 18 years suffering from deep thermal burns of up to 67% total body surface area were treated with NXB in three clinical trials. Seventy-seven children were treated with NXB in a phase I/II study, where 92.7% of the areas treated achieved complete eschar removal within 0.9 days from admission. Thirty-three children (17 NXB, 16 standard of care [SOC]) participated in a phase III randomized controlled trial. All wounds treated with NXB achieved complete eschar removal. Time to complete eschar removal (from informed consent) was 0.9 days for NXB vs 6.5 days for SOC (P < .001). The incidence of surgical excision was 7.9% for NXB vs 73.3% for SOC (P < .001). Seventeen of these children participated in a phase III-b follow-up study (9 NXB and 8 SOC). The average long-term modified Vancouver Scar Scale scores were 3.4 for NXB-treated wounds vs 4.4 for SOC-treated wounds (NS). There were no significant treatment-related adverse events. Additional studies are needed to strengthen these results.

Effect of Botulinum Toxin A on Muscle Healing and its Implications in Aesthetic and Reconstructive Surgery.

BACKGROUND: Muscle activity contributes to the enhancement of facial aging deformity, blepharospasm, cerebral palsy spasticity, trismus, torticollis, and other conditions. Myotomy of the involved muscles in order to reduce the deformity has variable success rates due to muscle healing and regeneration of activity. OBJECTIVES: The goal of this study was to investigate whether blocking striated muscle activity with Botulinum toxin (BtxA) during the healing time after myotomy alters the healing process and reduces long-term muscle activity. METHODS: Eighteen Sprague Dawley rats where divided into 3 groups: group A (n = 7) underwent myotomy of their Latisimus Dorsi muscle; group B (n = 7) underwent myotomy and injection of BtxA into their severed muscle; group C (n = 4) injection of BtxA only. Muscle strength was tested periodically using a grip test. RESULTS: Starting at week 16 and until the termination of study at week 22, group B (Myotomy + BtxA) showed significant reduction in muscle power compared to the two control groups. CONCLUSIONS: Addition of BtxA injection into a muscle immediately after myotomy may interfere with muscle healing and contribute to a more successful long-term result.

Bromelain-based enzymatic debridement of chronic wounds: A preliminary report.

Sharp debridement is currently considered most effective for debridement of chronic wounds; however, some patients do not have access to or cannot be treated by surgical methods. This study was designed to provide a first impression of the safety and efficacy of bromelain-based enzymatic debridement of chronic wounds. Two consecutive single-arm studies assessing the enzymatic debridement efficacy of a concentrate of proteolytic enzymes enriched in bromelain in chronic wounds was conducted in 2 medical centres. Patients were treated with up to 11 consecutive 4-hour enzymatic debridement sessions and then treated until wound closure. Twenty-four patients with chronic wounds of different aetiologies were enrolled. All wounds achieved an average of 68% ± 30% debridement in an average of 3.5 ± 2.8 enzymatic debridement 4-hour sessions. Seventeen responding wounds (venous, diabetic, pressure, and post-traumatic aetiologies) achieved an average 85% ± 12% debridement in 3.2 ± 2.5 applications. Seven non-responding wounds (arterial and post-surgical aetiologies) achieved an average 26% ± 13% debridement in 4.3 ± 3.5 applications. No treatment-related serious adverse events were observed, and the only adverse event attributed to the enzymatic debridement was pain. These preliminary results indicate the potential safety and efficacy of bromelain-based enzymatic debridement in chronic wounds. Larger controlled studies are needed to further investigate this indication.

Facial Reconstruction of a Mucormycosis Survivor by Free Rectus Abdominis Muscle Flap, Tissue Expansion, and Ocular Prosthesis.

Invasive sinonasal mucormycosis is a rare fungal infection that usually occurs in immunocompromised or diabetic patients, and it is often fatal. The authors present a case of a woman patient suffering from systemic lupus erythematosus and diabetes mellitus treated with prednisone, presenting with a rapidly progressive rhino-orbital-cerebral mucormycosis. She was successfully treated with combined intravenous antifungal therapy and radical debridement followed by complex defect reconstruction with a free vertical rectus abdominis myocutaneous flap, tissue expander, and ophthalmic prosthesis.

Defensive Medicine Among Plastic and Aesthetic Surgeons in Israel.

BACKGROUND: Defensive medicine (DM) includes medical practices that are aimed at avoiding liability rather than benefitting the patient. DM has not been well characterized among plastic surgeons. OBJECTIVES: The authors examined the extents of intended and unintended DM among members of the Israeli Society of Plastic and Aesthetic Surgery (ISPAS) and identified risk factors for DM. METHODS: A total of 108 ISPAS members were asked to complete a questionnaire that addressed physician attitudes toward DM and intended or unintended DM practices. RESULTS: Seventy-eight surgeons (72.2% response rate) returned the questionnaire, although some questionnaires were returned incomplete. Forty respondents acknowledged practicing DM (ie, DM group), and 33 respondents did not (ie, non-DM group). There were no between-group differences in gender, years of practice, or number of previous litigations. Thirty-one percent of respondents in the DM group indicated that they avoid certain surgical procedures, compared with 6% of respondents in the non-DM group (P = .008). In private practice, 66.2% of respondents stated that they obtain written informed consent twice before surgery, and 100% request preoperative blood-coagulation testing. In contrast, 40% and 74% of respondents in public practice, respectively, acknowledged these behaviors (for consent, P = .027; for testing, P = .0059). Sixty-three percent of respondents prescribe antibiotics for more than 24 hours postoperatively, and this practice was slightly more common in the DM group (34 prescribe antibiotics vs 21 in the non-DM group; P = .079). CONCLUSIONS: DM is highly integrated into the daily medical practices of plastic surgeons in Israel.

[REVIEW OF 30 YEARS OF RESEARCH AND DEVELOPMENT OF AN ENZYMATIC DEBRIDEMENT AGENT FOR BURNS].

INTRODUCTION: Early removal of burn eschar is a cornerstone of burn care. The most commonly practiced eschar removal technique for deep burns in modern burn care is surgical debridement but this technique is associated with surgical burden and leads to unnecessary excision of viable tissue. GOALS: To review 30 years of research and development of an enzymatic debridement agent for burns. METHODS: Studies performed during the last 30 years are reviewed in this manuscript. RESULTS: Patients who underwent enzymatic debridement had a significantly shorter time to complete debridement, the surgical burden was significantly lower, hand burns did not necessitate escharotomy, and the long term results were favorable. DISCUSSION: Early enzymatic debridement leads to an efficient debridement, preservation of viable tissue, a reduction in surgical burden and favorable long term results. CONCLUSION: We believe early enzymatic debridement will lead to better care for burn victims and perhaps, even to a paradigm shift in the treatment of burns.

Double Back Cut in Post-mastectomy Breast Skin (Fish-Shaped Skin Paddle) in Delayed Pedicled TRAM Flap Breast Reconstruction.

Breast reconstruction has become standard of care for female patients with breast cancer. The transverse rectus abdominis musculo-cutaneous flap (TRAMf) is the most common method of immediate or delayed autologous breast reconstruction following mastectomy. We share our experience with modified, double back cut of post-mastectomy skin in delayed pedicled TRAMf breast reconstruction, resulting in fish-shaped skin paddle. This sort of back cut is a simple, reliable way to obtain a natural, esthetically pleasant breast mound with inconspicuous hidden scars.

Total lip reconstruction with tendinofasciocutaneous radial forearm flap.

INTRODUCTION: Squamous cell carcinoma is a common tumour of lower lip. Small defects created by surgical resection may be readily reconstructed by linear closure or with local flaps. However, large tumours resection often results with microstomia and oral incompetence, drooling, and speech incomprehension. The goal of this study is to describe our experience with composite free radial forearm-palmaris longus tendon flap for total or near total lower lip reconstruction. PATIENTS AND METHODS: This procedure was used in 5 patients with 80-100% lip defect resulting from Squamous cell carcinoma. Patients' age ranged from 46 to 82 years. They are three male patients and two female. In 3 cases chin skin was reconstructed as well and in one case a 5 cm segment of mandible was reconstructed using radius bone. In one case where palmaris longus was missing hemi-flexor carpi radialis tendon was used instead. All patients tolerated the procedure well. RESULTS: All flaps totally survived. No patient suffered from drooling. All patients regained normal diet and normal speech. Cosmetic result was fair to good in all patients accept one. CONCLUSION: We conclude that tendino-fasciocutaneous radial forearm flap for total lower lip reconstruction is safe. Functional and aesthetic result approaches reconstructive goals.

Efficacy of transfer form implementation for adult burn patients between institutions to the Israeli National Burn Center.

Burns are serious injuries associated with significant morbidity and mortality. In Israel, burn patients are often transferred between facilities. However, unstructured and non-standardized transfer processes can compromise the quality of patient care and outcomes. In this retrospective study, we assessed the impact of implementing a transfer form for burn management, comparing two populations: those transferred before and after the transfer form implementation. This study included 47 adult patients; 21 were transferred before and 26 after implementing the transfer form. We observed a statistically significant improvement in reporting rates of crucial information obtained by Emergency Room clinicians and inpatient management indicators. Introducing a standardized transfer form for burn patients resulted in improved communication and enhanced primary management, transfer processes, and emergency room preparation. The burns transfer form facilitated accurate and comprehensive information exchange between clinicians, potentially improving patient outcomes. These findings highlight the importance of structured transfer processes in burn patient care and emphasize the benefits of implementing a transfer form to streamline communication and optimize burn management during transfers to specialized burn centers.

Early Enzymatic Burn Debridement: Results of the DETECT Multicenter Randomized Controlled Trial.

Since 1970 surgeons have managed deep burns by surgical debridement and autografting. We tested the hypothesis that enzymatic debridement with NexoBrid would remove the eschar reducing surgery and achieve comparable long-term outcomes as standard of care (SOC). In this Phase 3 trial, we randomly assigned adults with deep burns (covering 3-30% of total body surface area [TBSA]) to NexoBrid, surgical or nonsurgical SOC, or placebo Gel Vehicle (GV) in a 3:3:1 ratio. The primary endpoint was complete eschar removal (ER) at the end of the debridement phase. Secondary outcomes were need for surgery, time to complete ER, and blood loss. Safety endpoints included wound closure and 12 and 24-months cosmesis on the Modified Vancouver Scar Scale. Patients were randomized to NexoBrid (n = 75), SOC (n = 75), and GV (n = 25). Complete ER was higher in the NexoBrid versus the GV group (93% vs 4%; P < .001). Surgical excision was lower in the NexoBrid vs the SOC group (4% vs 72%; P < .001). Median time to ER was 1.0 and 3.8 days for the NexoBrid and SOC respectively (P < .001). ER blood loss was lower in the NexoBrid than the SOC group (14 ± 512 mL vs 814 ± 1020 mL, respectively; P < .0001). MVSS scores at 12 and 24 months were noninferior in the NexoBrid versus SOC groups (3.7 ± 2.1 vs 5.0 ± 3.1 for the 12 months and 3.04 ± 2.2 vs 3.30 ± 2.76 for the 24 months). NexoBrid resulted in early complete ER in >90% of burn patients, reduced surgery and blood loss. NexoBrid was safe and well tolerated without deleterious effects on wound closure and scarring.

Anacaulase-bcdb for the treatment of severe thermal burns.

INTRODUCTION: Accurate burn depth assessment and early excision of burn eschar with maximal dermal preservation are key concepts in the optimal care of burn injury. Although excision with knife has long since been standard of care, a newer technique for wound bed preparation utilizing a bromelain-based enzyme has gained popularity worldwide and may offer several advantages. AREAS COVERED: Here we report the pharmacologic properties, evidence for clinical efficacy, safety, and tolerability of anacaulase-bcdb for the treatment of deep partial thickness and full thickness burns. EXPERT OPINION: Anacaulase-bcdb is a safe, non-surgical, selective eschar removal agent. It offers advantages over surgical excision of burn with knife and fulfills two unmet needs: burn depth assessment and dermal preservation during excision. Evidence supports a faster time to complete eschar removal; reduced number of operations; reduction in the amount of autografting, length of stay, and blood loss; prevention of burn induced compartment syndrome; and improved cosmetic outcome.

Enzymatic Debridement of Deep Thermal Burns in the Russian Federation: First Experience.

Since its approval in Europe a decade ago, NexoBrid® enzymatic debridement of deep thermal burns has been gaining acceptance as standard practice around the world. The purpose of this study is to report the first experience with NexoBrid® in the Russian Federation. During 2019-2020, we conducted a post-registration clinical study assessing the safety and treatment results of NexoBrid® enzymatic debridement. The study involved 15 adult patients suffering from deep thermal burns over an area ≤15% of their total body surface area. Patients were treated with NexoBrid® within 3 days of injury, followed by spontaneous or surgical wound closure. Complete eschar removal was achieved in twelve patients, 80% eschar removal in two patients, and 70% in one patient. Complete spontaneous epithelialization of wounds was achieved in 12 patients (80%) within 18 ± 1.9 days after the start of treatment. We did not witness pathological scarring during follow-up, and there were no significant safety issues throughout the study. Early use of NexoBrid® resulted in rapid, effective, and safe eschar removal with good results and sufficient preservation of viable dermis to allow for spontaneous healing in 80% of patients. These results demonstrate the ability to minimize surgical intervention and hopefully lead to better long-term scarring results.

Helpful hints in deciding what and when to operate after enzymatic debridement.

INTRODUCTION: In recent years, it has become clear that the burn eschar in deep burns can be selectively removed using the enzymatically debriding agent NexoBrid® (EDNX). In deep partial-thickness burns, such selective debridement preserves all non-injured dermis, which is sometimes sufficient for spontaneous re-epithelization. Nevertheless, it can be extremely challenging to determine exactly what and when to operate after an EDNX procedure. In this manuscript, we sought to investigate the clinical aspect of the enzymatically debrided wound bed of laser Doppler imaging (LDI)-confirmed deep dermal and full-thickness burns after NexoBrid® application. This to evaluate the residual wound healing capacity and implement specific indications for surgical therapy after enzymatic debridement. MATERIAL AND METHODS: Mainly LDI-blue areas, determined between 48 h and 5d after burn and afterwards treated with EDNX were selected. Six practical and three expert EDNX users evaluated the high-quality digital images of the wound beds immediately post NexoBrid® removal and after a 2 h wet-to-dry (WTD) dressing period. RESULTS: One hundred and two mainly LDI-blue areas in 32 patients were analyzed. Regarding the early decision-making, there were no significant differences in the wound bed evaluations, wound healing assessment and treatment decision of all 9 EDNX users post EDNX removal versus post WTD. Moreover, there was a good to excellent consensus between the practical and expert EDNX users in the individual wound bed evaluations. Even in the evaluation of a newly developed wound bed color code, with 7 different colors/patterns to choose from, the consensus was 80%. There was also an 84% consensus on the decision whether or not to operate. All mainly LDI-blue areas with incomplete enzymatic debridement, determined during clinical investigation by expert EDNX users, required surgery. Additionally, the expert investigators demonstrated that the following wound bed characteristics were independent predictors of the need for surgical treatment: visible fat lobules (p = 0.028), translucent fat lobules (p < 0.001), dermal step-off in the wound bed (p < 0.001), visible blood vessels (p < 0.001) and coagulated blood vessels (p = 0.023). Also, higher color code ranges on our own developed wound bed classification were significantly related to a surgical intervention (p = 0.006). When including the LDI flux values, the perfusion units were significantly different (p < 0.001) between the exclusively LDI-blue areas treated conservatively (mean 145.7) and the areas ultimately treated with autografts (mean 119.5). CONCLUSION: To the best of our knowledge, this study is the first to address the clinical wound bed evaluation of LDI-confirmed deep burns after NexoBrid® application. Based on our results, it is recommended to evaluate the wound bed twice: immediately after removing NexoBrid® to assess the viability of the wound bed and after the WTD period to reach a more complete decision. During these evaluations, wound bed characteristics such as incomplete debridement, visible and/or translucent fat lobules, visible and/or coagulated blood vessels and a dermal step-off in the wound bed combined with a higher range (4-5) in the newly developed wound bed color code should lead to an early and reliable decision for skin grafting. For burn centers using LDI, mean flux values below 119.5PU - in addition to the above-mentioned wound bed evaluation - are a clear indicator for surgical therapy.

A Comparison of Topical Agents for Eschar Removal in a Porcine Model: Bromelain-enriched vs Traditional Collagenase Agents.

Surgical excision and grafting of deep partial-thickness (DPT) and full-thickness (FT) burns is a cornerstone of wound care. The use of commercially available topical enzymatic agents has been limited due to slower and less complete eschar removal than surgical excision. Using a porcine model of DPT and FT burns, we compared the eschar removal efficacy of a bromelain-enriched enzymatic agent derived from the stems of pineapple plants and a commercially available collagenase. We created 40 DPT and 40 FT burns on four anesthetized Yorkshire pigs. Eschar removal was initiated 24 hours later. Two pigs each were randomly assigned to collagenase or the bromelain-enriched agent. The bromelain-enriched agent was applied topically once for 4 hours followed by a 2-hour soaking. The collagenase was applied topically daily until complete removal of eschar or for up to 14 days. All bromelain-enriched treated FT burns underwent complete removal of the eschar after a single application while none of the collagenase-treated FT burns underwent complete removal of the eschar even after 14 days of treatment. All bromelain-enriched treated DPT burns had complete eschar removal after the single application. None of the collagenase-treated DPT burns experienced complete removal of eschar after 10 days; by day 14, 35% had complete eschar removal, 30% had >50% eschar removed, and 35% had <50% eschar removed. We conclude that eschar removal is quicker and more complete with the bromelain-enriched compared with collagenase debriding agent.

Blood Stream Infections in Burns: A 14-Year Cohort Analysis.

BACKGROUND: Blood stream infections are a significant cause of morbidity and mortality in burns, and pathogen identification is important for treatment. This study aims to characterize the microbiology of these infections and the association between the infecting pathogen and the hospitalization course. METHODS: We conducted a cohort study that included records of burn patients treated at the Soroka University Medical Center between 2007-2020. Statistical analysis of demographic and clinical data was performed to explore relationships between burn characteristics and outcomes. Patients with positive blood cultures were divided into four groups: Gram-positive, Gram-negative, mixed-bacterial, and fungal. RESULTS: Of the 2029 burn patients hospitalized, 11.7% had positive blood cultures. The most common pathogens were Candida and Pseudomonas. We found significant differences in ICU admission, need for surgery, and mortality between the infected and non-infected groups (p < 0.001). Pathogen groups differed significantly mean TBSA, ICU admission, need for surgery, and mortality (p < 0.001). Multivariate analysis showed flame (OR 2.84) and electric burns (OR 4.58) were independent risk factors for ICU admission and surgical intervention (p < 0.001). Gram-negative bacterial infection was found to be an independent predictor of mortality (OR = 9.29, p < 0.001). CONCLUSIONS: Anticipating specific pathogens which are associated with certain burn characteristics may help guide future therapy.

The Implications of a Dermatopathologist's Report on Melanoma Diagnosis and Treatment.

An accurate and comprehensive histopathology report is essential for cutaneous melanoma management, providing critical information for accurate staging and risk estimation and determining the optimal surgical approach. In many institutions, a review of melanoma biopsy specimens by expert dermatopathologists is considered a necessary step. This study examined these reviews to determine the critical primary histopathology Breslow score in which a histopathology review would be most beneficial. Histopathology reports of patients referred to our institute between January 2011 and September 2019 were compared with our in-house review conducted by an expert dermatopathologist. The review focused on assessing fundamental histologic and clinical prognostic features. A total of 177 specimens underwent histopathology review. Significant changes in the Breslow index were identified in 103 cases (58.2%). Notably, in many of these cases (73.2%), the revised Breslow was higher than the initially reported score. Consequently, the T-stage was modified in 51 lesions (28.8%). Substantial discordance rates were observed in Tis (57%), T1b (59%), T3a (67%) and T4a (50%) classifications. The revised histopathology reports resulted in alterations to the surgical plan in 15.3% of the cases. These findings emphasize the importance of having all routine pathologies of pigmented lesions referred to a dedicated cancer center and reviewed by an experienced dermatopathologist. This recommendation is particularly crucial in instances where the histopathology review can potentially alter the diagnosis and treatment plan, such as in melanoma in situ and thinner melanomas measuring 0.6-2.2 mm in thickness. Our study highlights the significant impact of histopathology reviews in cutaneous melanoma cases. The observed changes in Breslow scores and subsequent modifications in T-stage classification underline the need for thorough evaluation by an expert dermatopathologist, especially in cases of melanoma in situ and thin melanomas. Incorporating such reviews into routine practice within dedicated cancer centers can improve diagnostic accuracy and guide appropriate treatment decisions, ultimately leading to better patient outcomes.
