Fluorouracil for keloids

BACKGROUND: Bowen's disease (BD) is a precancerous in-situ squamous cell carcinoma and has a high recurrence rate with any single treatment modality, necessitating combination therapy for a successful outcome. AIM: This study aimed to the efficacy and safety of carbon dioxide (CO2 ) laser ablation followed by manual dermabrasion and intralesional 5-fluorouracil (IL 5-FU) injection as combination therapy for BD. MATERIALS AND METHODS: This was a retrospective, observational study comprising 29 clinically and histopathologically diagnosed BD patients with no history of prior treatment...

SIGNIFICANCE: Pathologic scarring occurs secondary to imbalances in the cellular mechanisms of wound healing and affects millions of people annually. This review article aims to provide a concise overview of the pathophysiology and management of pathologic scarring for clinicians and scientists alike. RECENT ADVANCES: Contemporary research in the field has identified aberrations in TGF-β/SMAD signaling pathways as key drivers of pathologic scar formation; indeed, this pathway is targeted by many treatment modalities and translational investigations currently underway...

BACKGROUND: Keloids are common benign skin lesions originating from a disorganized fibroproliferative collagen response; these lesions often lead to both physical and psychological problems. The optimal treatment for keloids is yet to be standardized. Intralesional injection, which is simple and nontraumatic, is one of the most commonly used treatment modalities for these lesions. In this study, we compared 5 different drugs (intralesional injections) for the treatment of keloids in terms of efficacy...

Injury to the skin can cause abnormal wound healing and continuous inflammation that leads to the formation of hypertrophic scars and keloids. These lesions often cause significant negative impact on a patient's life due to aesthetic, physical, social, and psychological consequences. Numerous treatment modalities exist for these hypertrophic scars and keloids, which include silicone sheeting, pressure garments, intralesional injection/topical application of scar-modulating agents, laser therapy, and surgical excision...

Introduction: Benign fibroproliferative scars that are larger than the initial lesion are called keloids. Keloids treatment in clinical practice is still difficult. Although there are various therapy choices, none is embraced by everyone or is relapse-free. Various treatment modalities such as intralesional corticosteroid injection with 5-fluorouracil (5-FU), fractional Er:YAG laser, pulsed dye laser (PDL), and others can be used either as monotherapies or combined therapies. Therefore, efforts should be made to select the treatment that will provide the best results...

BACKGROUND: The high recurrence rate after nonsurgical treatment of keloid is a major challenge for clinicians. Although there are many existing treatment options, how to optimize and upgrade the existing options and make a reasonable combination of utilization is our concern. The aim of this study is to provide a comprehensive non-surgical treatment for keloid-cocktail therapy. METHODS: According to the different changes of keloid with treatment, the treatment was divided into four stages, and different treatment schemes were adopted for each stage...

Hypertrophic scars (HTS) and keloids are pathologic scars that are products of a wound healing pathway error attributed to genetic and inflammatory causes (Leventhal et al., Arch Facial Plast Surg 8(6):362-368. https://doi.org/10.1001/archfaci.8.6.362 , 2006). Methods of pathologic scar treatment include intralesional agents, cryotherapy, surgical excision, pressure dressings, topical agents, laser resurfacing, radiotherapy, and other investigational therapies (Leventhal et al. 2006). The recurrence of pathologic scar is high across all treatment modalities, including the use of intralesional agents (Trisliana Perdanasari et al...

INTRODUCTION: Keloid is an abnormal fibroproliferative healing response characterized by excessive and invasive tissue growth beyond the wound boundaries. The conventional treatment involves injecting drugs such as triamcinolone acetonide (TA), 5-fluorouracil (5-FU), or their combination intralesionally. However, the pain associated with injections often leads to low patient compliance and treatment failure. The spring-powered needle-free injector (NFI) provides an affordable alternative option for drug delivery with reduced pain...

BACKGROUND: Keloids and hypertrophic scars cause physical and psychosocial problems. Combination 5-fluorouracil (5-FU) with triamcinolone acetonide (TAC) may enhance the treatment of pathological scars, although the evidence base is limited. OBJECTIVES: We aimed to evaluate the efficacy and complication rates of combination intralesional TAC and 5-FU in comparison to monotherapy intralesional TAC or 5-FU for the treatment of keloids and hypertrophic scars. METHODS: EMBASE, MEDLINE and CENTRAL were searched by two independent reviewers...

OBJECTIVES: Keloid is a highly aggressive fibrotic disease resulting from excessive extracellular matrix deposition after dermal injury. Intra-lesional injection of triamcinolone acetonide (TAC) in combination with 5-fluorouracil (5-FU) is a commonly used pharmacological regimen and long-term repeated injections can achieve sustained inhibition of keloid proliferation. However, the molecular mechanisms underlying the inhibitory effect on keloids remain insufficiently investigated. METHODS AND MATERIALS: This study performed single-cell RNA sequencing analysis of keloids treated with TAC+5-FU injections, keloids, and skins to explore patterns of gene expression regulation and cellular reprogramming...

BACKGROUND: Vocal fold (VF) scar can result from trauma, neoplasm, inflammatory processes, congenital causes, surgery and other etiologies. In general, once the vibratory margin of the VF has been scarred, it has not been possible to return VF function to normal; but often it can be improved. The drug 5-fluorouracil (5-FU) is a pyrimidine antimetabolic that has many clinical applications ranging from systemic chemotherapy to topical treatment of actinic keratosis and basal cell carcinoma of the skin...

BACKGROUND: The recurrence of keloids after intralesional injections is significant, and a review of the literature shows an inconsistent range of success rates. In this study, the modified medical proportion and intralesional injection method were intended to enhance the treatment effect. METHODS: Twenty patients completed the study. Regional block anesthesia (lidocaine, ropivacaine) was performed. Triamcinolone acetonide (40 mg/mL), 5-fluorouracil (25 mg/mL), and ropivacaine (7...

UNLABELLED: Keloids are the result of an abnormal wound-healing process and are associated with various risk factors. The majority of diagnoses are clinical. Successful treatment of keloid is challenging due to its nonregressing and recurring nature. CASE PRESENTATION: We discuss the case of a 30-year-old mongoloid male who had multiple swellings over his body for the past 10 years. More striking are the giant keloids that are present over his bilateral scapulae...

The objectives of this study are to evaluate the efficacy and safety of needle-free jet injections for dermatological indications and to provide evidence-based treatment recommendations. An electronic literature search was conducted in April 2022. Two reviewers independently selected studies based on predefined criteria and performed a methodological quality assessment using the Cochrane Collaborations risk-of-bias 2...

Exaggerated healing and remodeling after skin injury may cause hypertrophic and keloidal scars, which are associated with functional and quality of life impairment. There is limited guidance available regarding the relative effectiveness of therapies for hypertrophic scars and keloids. In this review, we aim to compare the effectiveness of treatments for hypertrophic scars and keloids. MEDLINE, Embase, Scopus, and the Cochrane Collaboration database were searched from inception to March 2019 for randomized control trials of treatments for hypertrophic and keloid scars that included 20 or more patients...

Individuals with skin of color represent a diverse population of racial and ethnic backgrounds, including but not limited to Black or African American, American Indian or Alaska Native, Asian American or Pacific Islander, Hispanic or Latino, and Middle Eastern or North African. Dermatologic health disparities exist in part because of systemic racism and are exacerbated by inadequate physician training and a lack of high-quality research on skin diagnoses that disproportionately affect people with skin of color...

Hypertrophic scars and keloids can have significant detrimental effects on patients both psychosocially and functionally. A careful identification of patient risk factors and a comprehensive management plan are necessary to optimize outcomes. Patients with a history of dystrophic scarring should avoid unnecessary procedures and enhance the wound-healing process using various preventive strategies. As there is no single, fully efficacious treatment modality, prevention remains the best approach in reducing aberrant scar formation...
