Abstract
Keloids are benign, fibroproliferative dermal tumours, often arising after trauma, that are more common in darker skin types. Numerous therapeutic options have been employed for the treatment of keloids; however, there is no one gold standard approach. Five-fluorouracil, a potent chemotherapeutic agent, has emerged as a promising therapeutic option. Therefore, this systematic review, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, focused on providing a broad overview of the use of 5-fluorouracil for the management of keloids. Forty studies (2325 patients) met inclusion criteria and investigated 5-fluorouracil for keloid management, with 19 studies (1043 patients) including a 5-fluorouracil monotherapy group. Five-fluorouracil monotherapy demonstrated consistent keloid improvement with >254 keloids injected across various anatomical regions. Five-fluorouracil monotherapy was most often compared to intralesional triamcinolone acetonide, utilizing the Patient and Observer Scar Assessment Scale and the Vancouver Scar Scale. The most common keloid parameters assessed were height, size, volume, width, length, induration, pruritus, and erythema. Five-fluorouracil monotherapy exhibited substantial improvements, with weight averages of 73% of patients experiencing >25% improvement and 67% achieving >50% improvement. Relapse rate was 16% at 27 weeks after 5-fluorouracil monotherapy treatment. Limitations included potential selection bias, language restrictions, and heterogenous data analysis among studies. Overall, our findings underscore the potential effectiveness of 5-fluorouracil monotherapy in the management of keloids, with an encouraging safety profile. Larger prospective trials are needed to determine optimal therapy or combination therapy for the management of keloids. This detailed compilation of treatment protocols, outcomes, and relapse rates stand as a valuable resource for further research and clinical applications.

Fu S, Duan L, Zhong Y, Zeng Y. Comparison of surgical excision followed by adjuvant radiotherapy and laser combined with steroids for the treatment of keloids: A systematic review and meta-analysis. Int Wound J 2023; 21:e14449. [PMID: 37967571 PMCID: PMC10895202 DOI: 10.1111/iwj.14449] [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: 09/04/2023] [Accepted: 10/10/2023] [Indexed: 11/17/2023] Open
Abstract
This meta-analysis aims to evaluate and compare the effect of surgical excision followed by adjuvant radiotherapy and laser combined with steroids on keloids. Relevant studies reporting the recurrence rate or incidence of adverse events (AEs) were retrieved from the PubMed, Web of Science, Embase and Cochrane Library databases through August 2023. The quality of noncomparative single-arm clinical trials was evaluated using the methodological index for nonrandomised studies (MINORS) Methodological items. This meta-analysis was conducted utilizing Stata 12.0 statistical software. 26 studies involving 989 patients were included in the analysis. The recurrence rate in the laser combined with steroids therapy group (12.2%, 95% confidence interval [CI]: 5.9%-18.5%) was lower than that of the surgical excision combined with radiotherapy group (13.5%, 95% CI: 6.6%-22.2%). For the incidence of AEs, relatively low incidence of atrophy (0.0%, 95% CI: 0.0%-1.2%), telangiectasia (3.2%, 95% CI: 0.4%-7.6%), erythema (2.3%, 95% CI: 0.0%-10.6%), infection (0.2%, 95% CI: 0.0%-1.6%) and high hyperpigmentation rate (8.3%, 95% CI: 4.2%-13.4%) were obtained in the surgical excision combined with radiotherapy group. Compared with surgical resection followed by radiotherapy, the combination of laser and steroids for keloids showed a lower hyperpigmentation rate (6.5%), as well as a higher incidence of atrophy (22.7%), telangiectasia (6.4%), erythema (3.3%) and infection (3.3%). Only a hypopigmentation rate of 2.9% was obtained in patients treated with surgical excision plus radiotherapy. Current evidence revealed that surgical excision followed by adjuvant radiotherapy and laser combined with steroids therapy were effective and safe treatments for keloids, with relatively low recurrence rate and complication rate. Comparative studies are needed to further compare the effects of these two combination therapies on keloids.

Abstract
BACKGROUND Keloids and hypertrophic scars frustrate patients by the deformity of appearance and organ dysfunction. Many modalities had been tried in clinic practice, but the results are unsatisfied. OBJECTIVE We retrospectively analysed the combined application of bleomycin and triamcinolone for the treatment of keloids and hypertrophic scars. METHODS The combination of bleomycin and triamcin acetonide was applied to the treatment of keloids and hypertrophic scars, 86 cases accepted the treatment. Follow-up 2-5 years after treatment. RESULTS (1) The pain of scars and itching symptoms have basically subsided through treatment. (2) After drug injection treatment, the keloid began to shrink, some of the keloids disappeared. (3) Small keloids did not recur after treatment. Large keloids had local recurrence after treatment. When further treatment was given, the recurrence disappeared. CONCLUSION The combined application of bleomycin and triamcin acetonide can effectively cure keloids and hypertrophic scars.

Abstract
Raised dermal scars including hypertrophic, and keloid scars as well as scalp-associated fibrosing Folliculitis Keloidalis Nuchae (FKN) are a group of fibrotic raised dermal lesions that mostly occur following cutaneous injury. They are characterized by increased extracellular matrix (ECM) deposition, primarily excessive collagen type 1 production by hyperproliferative fibroblasts. The extent of ECM deposition is thought to be proportional to the severity of local skin inflammation leading to excessive fibrosis of the dermis. Due to a lack of suitable study models, therapy for raised dermal scars remains ill-defined. Immune cells and their associated markers have been strongly associated with dermal fibrosis. Therefore, modulation of the immune system and use of anti-inflammatory cytokines are of potential interest in the management of dermal fibrosis. In this review, we will discuss the importance of immune factors in the pathogenesis of raised dermal scarring. The aim here is to provide an up-to-date comprehensive review of the literature, from PubMed, Scopus, and other relevant search engines in order to describe the known immunological factors associated with raised dermal scarring. The importance of immune cells including mast cells, macrophages, lymphocytes, and relevant molecules such as cytokines, chemokines, and growth factors, antibodies, transcription factors, and other immune-associated molecules as well as tissue lymphoid aggregates identified within raised dermal scars will be presented. A growing body of evidence points to a shift from proinflammatory Th1 response to regulatory/anti-inflammatory Th2 response being associated with the development of fibrogenesis in raised dermal scarring. In summary, a better understanding of immune cells and associated molecular markers in dermal fibrosis will likely enable future development of potential immune-modulated therapeutic, diagnostic, and theranostic targets in raised dermal scarring.

Keloid treatments: an evidence-based systematic review of recent advances. Syst Rev 2023; 12:42. [PMID: 36918908 PMCID: PMC10012475 DOI: 10.1186/s13643-023-02192-7] [Citation(s) in RCA: 16] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 02/15/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Keloids are pathologic scars that pose a significant functional and cosmetic burden. They are challenging to treat, despite the multitude of treatment modalities currently available. OBJECTIVE The aim of this study was to conduct an evidence-based review of all prospective data regarding keloid treatments published between 2010 and 2020. METHODS A systematic literature search of PubMed (National Library of Medicine), Embase (Elsevier), and Cochrane Library (Wiley) was performed in November of 2020. Search strategies with the keywords "keloid" and "treatment" were performed by a medical librarian. The search was limited to prospective studies that were peer-reviewed, reported on clinical outcomes of keloid therapies, and were published in the English language between January 1, 2010, and November 24, 2020. RESULTS A total of 3462 unique citations were identified, of which 108 studies met inclusion criteria. Current literature supports silicone gel or sheeting with corticosteroid injections as first-line therapy for keloids. Adjuvant intralesional 5-fluorouracil (5-FU), bleomycin, or verapamil can be considered, although mixed results have been reported with each. Laser therapy can be used in combination with intralesional corticosteroids or topical steroids with occlusion to improve drug penetration. Excision of keloids with immediate post-excision radiation therapy is an effective option for recalcitrant lesions. Finally, silicone sheeting and pressure therapy have evidence for reducing keloid recurrence. CONCLUSIONS This review was limited by heterogeneity of subject characteristics and study outcome measures, small sample sizes, and inconsistent study designs. Larger and more robust controlled studies are necessary to further understand the variety of existing and emerging keloid treatments, including corticosteroids, cryotherapy, intralesional injections, lasers, photodynamic therapy, excision and radiation, pressure dressings, and others.

Abstract
Background Combined therapy for keloids is currently recommended. Surgery is one of the main options, but the measures to prevent recurrence after excision are still being explored. Objective The randomized controlled study aimed at evaluating the efficacy of excision followed by intralesional low concentrations of 5-fluorouracil (5-FU)(12.5 mg/mL) and betamethasone. Methods Sixty patients were randomly assigned to three groups. Patients in group A had excision followed by 5-FU and betamethasone intralesional injections, group B had 5-FU and betamethasone intralesional injections, and group C had excision followed by radiotherapy. Efficacy parameters were assessed from 8 to 12 months, including improvement on the Vancouver Scar Scale (VSS) and the Patient and Observer Scar Scale (POSAS), as well as side effects and recurrence. Trial registration number: ChiCTR2100046025. Results After 4 months' treatment, the improvement of the VSS and POSAS scores in group A was not different from that in group C (P > 0.05) but was superior to that in group B (P < 0.05); the pain and pruritus of the three groups were relieved more than 50%. After 8 to 12 months' follow-up, there was no statistical difference in the incidence of side effects and recurrence among the groups (P > 0.05). Conclusion Excision followed by intralesional low concentrations of 5-FU (12.5mg/mL) with betamethasone is a safe and sustainable treatment for keloid, with no significant difference from excision followed by radiotherapy.

Abstract
Background Although multiple methods have been proposed to treat auricular keloids, low curative effects and high recurrence rates are currently major clinical problems. Thereinto, surgery combined with radiotherapy and triamcinolone acetonide injection is considered to be the proper choice for comprehensive treatment of auricular keloids. This study aimed at evaluating the therapeutic effect of individualized surgery combined with radiotherapy for the treatment of auricular keloids. Methods From February 2014 to February 2017, 67 patients with 113 auricular keloids in total were enrolled in this study. According to specific conditions of lesions, the local tissue and patients’ individual wishes, different surgical methods were selected to analyze the scar excision and repairment of the defect. Within 24 h after the keloid was excised, 5 MeV electron beam irradiation by the linear accelerator was used by radiotherapy with a total dose of 20 Gy at interval of 1 day for 10 consecutive times. Triamcinolone acetonide was injected immediately after surgery, and per month afterward in the following three months. Results 113 keloids in total were received treatment. The follow-up period was 24 months. Fourteen keloids (12.39%) showed subjective recurrence with a success rate of 87.61%. Wilcoxon matched-pairs rank-sum test was used to compare the differences of the 24-month postoperative VSS scores and the preoperative VSS scores. The VSS scores were as follows: 82 keloids (72.57%) scored less than 5 points (good result), 21 keloids (18.58%) scored 6 to 10 points (fair result), and only 10 keloids (8.85%) scored more than 10 points (bad result). The effective rate was 91.15%. Conclusions Individualized surgery combined with early postoperative radiotherapy and triamcinolone acetonide injection is an ideal treatment method to ensure good auricular appearance, low incidences of complications and recurrence based on effective treatment of auricular keloids.

Abstract
PURPOSE Ear keloids lead to psychological problems in the patient by causing complaints, such as itching and swelling. It is highly resistant to treatment, and recurrences are frequent. In the present study, the purpose was to investigate the treatment success of the intralesional steroid and PRP combination in addition to surgical excision in ear keloids. The 5-year recurrence rates and adverse effects of both treatments were also compared in this respect. MATERIALS AND METHODS In this study, 60 patients between the ages of 16 and 65 who were followed up between 2015 and 2020 due to ear keloids were evaluated retrospectively. Patients were divided into 3 different groups (n = 20) as (A-B-C). There were patients who had only intralesional steroid injections due to ear keloids in Group A, patients who had intraoperative/postoperative steroid injections combined with surgical excision were in Group B, and patients who had intraoperative/postoperative steroid+intraoperative Platelet-Rich Plasma (PRP) injections combined with surgical excision were in Group C. RESULTS It was found that the 5-year recurrence rate was the lowest in Group C (Surgical Excision+PRP + TAC). The 5-year recurrence rate of Group C was significantly lower when compared with other groups (p < 0.05). When the 5-year recurrence rate of Group A (TAC) and B (Surgical Excision+TAC) was compared, the recurrence rate of Group B was significantly lower (p < 0.05). When the adverse effects were compared, no significant differences were detected between two Groups (A-B) in terms of Skin Atrophy and Telangiectasia. Significant differences were detected between patients in Group C and other groups (p < 0.05). No significant differences were detected between Group B and C (p = 0.832). CONCLUSION The combination of surgical excision with Intralesional TAC and PRP treatment in patients with ear keloids should be considered as a highly successful multimodal treatment in terms of low recurrence and adverse effects.

Abstract
Background: Keloids are an abnormal proliferation of scars that can involve large areas of tissue beyond the original injury site. Hypertrophic scars are similar clinically, but do not exceed the original scar limits. These scarring abnormalities can cause noxious symptoms such as pain, tenderness, itching, and ulcerations. The aim of this review is to discuss current therapies for both types of abnormal scarring, and to determine if guidelines can be provided for excisional treatment with adjuvant therapies versus non-excisional methods. Methods: A systematic literature search was performed through the Web of Science database. The search revolved around keywords such as “keloid,” “hypertrophic scars,” and “treatment.” Articles were reviewed and screened for inclusion and exclusion criteria. The review focuses on an analysis and summarization of randomized control trials regarding keloid or hypertrophic scar treatments. Results: The original searches produced 1161 and 1275 articles for keloid and hypertrophic scars, respectively. In total, 316 duplicates were found. After accounting for 2014–2019 publication time, 655 keloid and 893 hypertrophic scar articles were reviewed. This resulted in 15 articles that pertained to treatment and randomized control trials. Conclusions: Keloids and hypertrophic scars present a clinical challenge. Based on qualitative review of recurrence, neither excision plus adjuvant therapy or nonsurgical treatments can be recommended preferentially at this time. More research is needed to determine if recurrence rate bias exists between the treatment regimens, as excisional treatment plus adjuvant therapy is reserved for refractory scars.

5-Fluorouracil Management of Oculofacial Scars: A Systematic Literature Review. Ophthalmic Plast Reconstr Surg 2021; 36:222-230.

Abstract
PURPOSE To review the literature for the safety and efficacy of intralesional 5-fluorouracil (5-FU) in the management of oculofacial scars. METHODS A literature search was performed in July 2019 in the PubMed database to identify reports of the use of 5-FU injections for modulating oculofacial cutaneous scars. The search yielded 152 articles, of which 15 met criteria outlined for assessment. Data were abstracted from these 15 relevant articles. RESULTS While there were no high-level prospective randomized controlled trials, 8 were lower-quality randomized controlled trial, 3 were retrospective cohort studies, and 4 were case series. Most studies pooled results of facial and nonfacial cutaneous applications. Three studies focused solely on oculofacial applications, and these were all lower-level evidence studies. The study outcomes included scar dimension reduction, erythema, patient satisfaction score, observer assessment of scar improvement, and recurrence rates. 5-Fluorouracil was administered as monotherapy or as part of multimodality treatment with other agents (usually corticosteroids) or with CO2 laser, radiotherapy, or pulsed dye laser. 5-Fluorouracil was usually given as an intralesional injection, but in some studies, it was applied topically after micropuncture of the skin. The number and timing of treatments varied between studies. Overall, the level of safety of 5-FU was high. Pain with injection was the most common reported side effect. Other common adverse side effects included pruritus, telangiectasias, changes in pigmentation, and purpura, and 2 studies noted more serious events, such as ulceration, superficial necrosis, and local infection. There were no severe side effects such as anaphylaxis, immune suppression, secondary malignancy, systemic infection, blindness, or death. In all studies, 5-FU was associated with prophylaxis of oculofacial scars or improvement of keloids or hypertrophic scars in terms of reducing size, erythema, and pruritus. 5-Fluorouracil application was associated with favorable patient satisfaction and observer assessment scores especially compared with corticosteroid injections alone. CONCLUSIONS High-quality randomized controlled trials are currently lacking, and the existing literature is predominately not specific to use of 5-FU on the face. These studies, however, suggest that intralesional 5-FU is safe and probably more effective than other options in the management of cutaneous scars in the oculofacial region. The delivery methods, timing, dosing, and concomitant therapies were highly variable. Further high-quality controlled studies specific to oculofacial scars may be indicated to assess the efficacy of 5-FU and to establish the best protocols for administering this medication.

Abstract
BACKGROUND Research evaluating the efficacy of multimodal therapy for the treatment of keloids has reported combination regimens are most effective. OBJECTIVE To compare recurrence rates for keloids treated with surgery plus one adjuvant intervention (dual therapy) versus surgery plus 2 or more adjuvant interventions (triple therapy). MATERIALS AND METHODS Systematic literature review and meta-analysis of combination treatment for keloids. RESULTS After full-text review, we included 60 articles representing 5,547 keloids: 5,243 received dual therapy, 259 received triple therapy, and 45 received quadruple therapy (the latter 2 groups were combined for analysis). The difference in recurrence rates between dual (19%) and triple therapy (11.2%) was not significant (p = .343). However, the difference in recurrence rates between dual therapy using surgery and radiation (18.7%) and triple therapy using surgery, radiation, and a third intervention (7.7%) was significant (p = .002). The differences for surgery and intralesional triamcinolone (TAC) showed trends toward significance, because keloids treated with dual therapy (21.7%) had a higher recurrence rate than those treated with triple therapy comprised of surgery, TAC, and another intervention (13.7%; p = .099). CONCLUSION Triple therapy using surgery plus radiation and/or TAC as one of the adjuvant treatment modalities may achieve the lowest recurrence rates for keloids.

Abstract
BACKGROUND Recurrence rates of keloids have generally been reported at one time point. However, the longer the duration after treatment, the greater the likelihood that such lesions will recur. In this study, we analysed the time to recurrence during long-term follow-up. MATERIAL AND METHODS We retrospectively reviewed recurrence-free interval in 52 patients with keloid (age 8-79 years) who had been treated between June 2006 and January 2011 using a standardised protocol developed by our group. RESULTS Mean duration of follow-up was 37.5 (range, 7-120) months in patients with keloid. Kaplan-Meier survival curves revealed a statistically significant difference in recurrence-free interval between ear keloids and keloids excluding ear keloids. Recurrence rate for keloids was high in the first 2 years after treatment. CONCLUSIONS Kaplan-Meier analysis was useful for understanding the tendency of recurrence of keloids after treatment using a standardised protocol.

Abstract
Commonly affecting those with skin of color, keloids are an aberrant wound response that leads to wound tissue expanding above and beyond the original cutaneous injury. Keloids are notoriously and particularly difficult to treat because of their tendency to recur after excision. The current standard of care is intralesional steroid (triamcinolone acetonide). However, because no therapy has yet proven to be fully curative, keloid treatments have expanded to include a number of options, from injections to multimodal approaches. This review details current treatment of keloids with injections (bleomycin, verapamil, hyaluronic acid and hyaluronidase, botulinum toxin, and collagenase), cryotherapy, laser, radiofrequency ablation, radiation, extracorporeal shockwave therapy, pentoxifylline, and dupilumab.

Abstract
Background One of the first-line options to treat keloid scars is corticosteroid injection after excision of the existing scar. A thorough literature search has shown a lack of research on the injection of corticosteroid injection immediately after the excision of the existing caesarean section keloid scars. Therefore, in the proposed study, we aim to investigate the effect of surgical excision and corticosteroid (triamcinolone acetonide) injection immediately after surgical removal of old caesarean section keloid scars on the recurrence of the scars. This is a protocol for a randomised controlled trial. Methods/design Pregnant women (n = 150), who attend antenatal clinics at Westmead Hospital in New South Wales, Australia, have a keloid scar from a previous caesarean section, meet the inclusion criteria and sign the consent form, will be randomised to either the control or the intervention group. The control group will receive surgical excision of the keloid scar at the beginning of the procedure during skin incision. The baby will be delivered according to normal procedures, and routine wound closure will be performed in accordance with National Institute for Health and Care Excellence guidelines. The intervention group will receive surgical excision of the keloid scar after the delivery of the baby, and closure of the uterus layers, rectus sheath and the fat layer will be completed as explained above. Then, triamcinolone acetone will be injected sub-dermally at the time of wound closure. Two ampules of triamcinolone acetonide will be administered at a single dose; each ampule contains 10 mg/1 ml active medication. The surgeon will inject one ampule along the entire length of the upper edge of the skin incision and one ampule along the entire length of the lower edge of the skin incision, using a 25 G needle. After the procedure is completed, the surgeon will fill in the post-operation survey. The participants will be followed up post-operation, daily on the ward and then at 6 weeks, 6 months and 12 months post-partum. Main outcomes are (1) keloid formation after caesarean section and (2) changes in the appearance and specification of the keloid scar after the intervention. Discussion We anticipate that surgical excision and steroid injection will be a safe, lasting and cost-effective treatment in the management of caesarean keloid scars which will be useful for patients unable to undergo cosmetic surgery due to clinical or financial reasons.

Abstract
Introduction: Hypertrophic scars and keloids are challenging to manage due to recurrence
and often sub-optimal response to treatment. There is a lack of both
definitive treatment standards and randomised controlled trials comparing
therapeutic options. While a wide array of procedures has been utilised to
improve traumatic burn scars, such interventions have been used with varying
degrees of success. Some reported methods include intralesional injections
of anti-inflammatory and anti-mitotic medications, laser-based therapy,
topical therapies, cryotherapy, silicone gel sheeting, pressure therapy,
radiotherapy and reconstructive surgery. Case: We report a case of extensive traumatic burn scarring on the head and neck
successfully treated with a multimodal approach comprised of an infrequently
used modified subcision technique to deliver alternating intralesional
injections of anti-inflammatory (high-dose steroid) and anti-metabolite
(5-flurouracil) concurrently with a series of laser (epilatory, vascular and
fractional) treatments. Methods: Our treatment modality utilised a subcisional technique to deliver
intralesional steroid and anti-metabolite medications directly into scar
tissue to downregulate inflammation and inhibit collagen synthesis.
Alexandrite, fractional and pulsed dye laser therapy was employed to improve
skin texture, reduce dyschromia and reduce tissue burden of hypertrophic
scar and keloid tissue, resulting in improved mobility and skin
elasticity. Conclusion: Our case supports a combined medical and procedural, subcisional, approach to
successfully treat a patient with extensive hypertrophic scarring and keloid
formation with associated hair entrapment after a head and neck burn.
Head and neck scarring can result in significant psychological and physical
impairments that may interfere with a patient’s daily life activities and
self-esteem. Burn injuries can result in hypertrophic scars and keloids that are
large in size, out of proportion to the initial area of injury, thought to be
due to inflammation that increases collagen production in the skin. In our case
report, we utilise a combined, non-surgical method of steroid and
anti-metabolite injections as well as laser technology to successfully reduce
the symptoms and appearance of large head and neck scars. Treatments consisted
of a non-invasive combination of injections into the scar tissue delivering
medication to reduce inflammation, pulsed dye laser to aid in decreasing scar
thickness and Alexandrite laser to reduce inflammation associated with trapped
hair follicles. One session of erbium fractional laser therapy was performed
with local anaesthesia, creating microscopic wounds to stimulate collagen
remodelling in the skin and facilitate resurfacing and healing of the scar.
These treatment sessions were performed outpatient and occurred at eight-week
intervals for 10 months. Results included decreased associated itching,
increased mobility of the head and neck, and improved skin texture and colour.
Our patient also reported an overall improvement in his mental wellbeing.
