Abstract
AIMS Many individuals suffer from keloids that are refractory to standard treatment modalities, including surgical excision alone. Radiation therapy can be used to reduce the risk of recurrent keloids post-operatively, as well as be used as primary treatment for keloids not amenable to surgical resection. The purpose of this study was to review our institutional experience of radiation therapy for keloid management. MATERIALS AND METHODS A retrospective review of patients treated with radiation therapy for keloids between 2014 and 2020 at our institution was performed. RESULTS A total of 70 keloids in 41 patients were treated. For the 55 keloids treated with post-operative radiation therapy (16Gy delivered in 2 fractions), 82.5% (33/40) of evaluable lesions did not recur. Among the 15 keloids treated with definitive radiation therapy (24Gy delivered in 3 fractions), 78.6% (11/14) of evaluable keloids showed complete flattening, and 14.3% (2/14) had partial flattening. Both acute and late toxicities were mild, with only a single instance of grade 3 toxicity (dermatitis). CONCLUSION Our study confirms that radiation therapy has a role in reducing the risk of keloid recurrence post-operatively, and plays an important role in the definitive management of unresectable keloids.

Abstract
BACKGROUND Different combinations of excision and adjuvant therapies have been applied to improve outcomes for earlobe keloids, though evidence in this field is still lacking. OBJECTIVES This study sought to systematically investigate efficacy and safety of these treatments. METHODS We conducted a systematic search on PubMed, Embase, Web of Science, and Cochrane Library to find all relevant studies. Meta-analysis of recurrence rates (RRs) and adverse event rates with 95% confidence intervals, and individual participants data (IPD) were calculated for each intervention when possible. Otherwise, narrative syntheses were performed. RESULTS A total of 85 articles, covering 23 treatments for earlobe keloids, were included, indicating a preference for multiple combination therapy. The estimated RRs for 6 interventions (i.e., excision monotherapy, combinations of excision with imiquimod, pressure therapy, radiotherapy, steroids, and steroids with pressure therapy) appeared to be comparable. Electron radiotherapy was found to have potential advantages over X-ray treatment, contributing to the observed heterogeneity. Further meta-analysis using IPD revealed that both combination therapies of excision plus steroid therapy (p=0.003) and excision plus radiotherapy (p=0.003) yielded better recurrence-free survival compared to excision alone. The median recurrence-free interval for combination therapy was 10 months. Adverse event rates were similar among different intervention groups. CONCLUSIONS This study suggests that combining excision with radiotherapy or perioperative steroid therapy has the potential to improve prognosis of earlobe keloids without increasing the risk of adverse events. Overall evaluation of patients' conditions and further studies with sufficient follow-up are warranted for clinical practice.

Abstract
OBJECTIVE Keloids and hypertrophic scars are benign fibroproliferative lesions that occur as a result of skin injury. Postoperative radiation therapy is used to reduce the recurrence rate because of the high recurrence rate with surgical treatment alone. This study aimed to identify the risk factors for recurrence after postoperative electron beam radiotherapy. MATERIALS AND METHODS Patients with keloid or hypertrophic scars with at least one lesion and who underwent postoperative electron beam radiotherapy at our institution from June 2013 to March 2022 were included in the study, while patients with a follow-up period of fewer than three months were excluded. RESULTS A retrospective analysis was performed on 94 lesions in 81 patients. Exactly two years after the treatment, the actuarial local control rate was 86.4%. The chest wall, shoulder, and suprapubic area were identified as high-risk recurrence sites. Compared to other body sites, these sites had significantly lower local control rates (two-year local control rates: 75.5% vs. 95.2%, P = 0.005). After multivariate analysis, treatment site (P = 0.014), male gender (P = 0.019), and younger age (P = 0.029) were revealed to be statistically significant risk factors for local recurrence. Risk factors for keloid recurrence after postoperative electron beam radiotherapy were therefore identified. CONCLUSION This result could be used for follow-up and as a determinant for the optimal dose/fractionation of postoperative radiotherapy.

Abstract
BACKGROUND Keloids are a fibroproliferative skin disorder with a high recurrence rate. Combined therapies are often used in clinical treatment, but, in addition to the relatively high risk of relapse and complexity of the treatment process, side effects remain unknown for combination therapies. METHODS A total of 99 patients with keloids in 131 positions were included in this retrospective study. Fractional CO 2 laser therapy was first applied with energy ranging from 360 to 1008 mJ; then, 6-Mev, 900-cGy electron beam irradiation was applied twice. The first pass was initiated within 24 hours after the laser therapy, and the second pass was performed on the seventh day after laser therapy. The Patient and Observer Scar Scale evaluated the lesions before the treatment and at 6, 12, and 18 months after treatment. At each follow-up visit, the patients filled out a questionnaire on recurrence, side effects, and satisfaction. RESULTS The authors found a significant decrease in total Patient and Observer Scar Scale score [29 (23, 39) versus 61.2 ± 13.4; P < 0.001] at the 18-month follow-up compared with the baseline value (before the therapy). A total of 12.1% of the patients had recurrences during the 18-month follow-up period (11.1% partial recurrence and 1.0% complete recurrence). The total satisfaction rate was 97.0%. No severe adverse effects were observed during the follow-up period. CONCLUSIONS Laser combined with radiotherapy is a new comprehensive therapy comprising ablative lasers and radiotherapy for keloids. It had excellent clinical efficacy, low recurrence rate, and no serious adverse effects. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
The aim of this study was to investigate the effect of postoperative electron radiotherapy (RT) on local control for keloids and to identify risk factors for recurrence. The clinical data of 82 patients treated at our institution from January 2015 to October 2019 were collected. The data included the general condition of the patients, clinical characteristics of the keloids, treatment plan, local control, and treatment side effects. A total of 82 patients (129 keloids) were included. The study included 23 men (28%) and 59 females (72%). The median patient age was 32 years (range, 18-67 years). Twenty-six recurrences were observed, and the 1-, 3-, and 5-year local control rates were 93%, 81%, and 73%, respectively. Univariate analysis revealed that age (P = .03), hypertension (P = .04), scar shape (P < .001), primary site (P = .02), maximum lesion diameter (P < .001), pain and itching (P = .005), local tension (P = .005), and infection (P < .001) were risk factors for local recurrence. Multivariable analysis revealed that maximum lesion diameter (P < .001), infection (P < .001), interval between surgery and RT (P = .02), and previous treatment (P = .02) were independent risk factors. Complete excision of keloids combined with electron RT is safe and seemingly effective. For keloids with a high risk of recurrence, more aggressive treatment should be chosen, and further prospective studies are needed to explore the optimal treatment.

Abstract
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. When prevention therapies fail, keloids have been shown to be respond to a variety of therapies including topical and injectable corticosteroids, 5-fluorouracil, radiotherapy, lasers, and surgical excision, all with varying efficacies. As such, management should be tailored to the individual patient's risk factors with the use of combination therapies to reduce recurrence rates. Still, keloid and hypertrophic scar therapies are widely diverse with novel treatment modalities providing alternatives for recurring lesions. Laser-assisted drug delivery, skin priming, and novel topical therapies may provide alternative options for the management of hypertrophic scars and keloids.

Abstract
Abstract
Background The treatment of keloidal scars with radiotherapy has been practiced for more than a century. Radiotherapy post-surgery has been deemed necessary and effective in preventing recurrence but still, no clear guidelines exist as to the best modality of radiotherapy, the ideal dose, and the time it should be given for keloidal scars. The purpose of this study is to confirm the effectiveness of this treatment and address these issues.
Methods Since 2004, 120 patients presenting with keloidal scars were seen by the author. Out of them, 50 were managed with surgery followed by HDR brachytherapy/electron beam radiotherapy delivering 2000 rads to the scar within 24 hours of surgery. Patients were followed up for at least 18 months to assess the scar status and the recurrence of keloids. Recurrence was defined as the appearance of a nodule or an obvious return of the keloid within 1 year of treatment.
Results Three patients developed a nodule in the scar, which was deemed a recurrence, making an incidence of 6%. There was no major problem after immediate postoperative radiotherapy. Five patients had delayed healing at 2 weeks and a hypertrophic scar was noted in five patients at 4 weeks that settled with conservative measures.
Conclusion Treating the vexing problem of keloids with surgery and immediate postoperative radiotherapy is safe and effective. We recommend that this be adopted as the standard treatment in keloid management.

Abstract
Postoperative radiation therapy has been shown to significantly reduce recurrence rates of keloids after surgical excision. Adverse effects of radiation therapy in this setting are generally minimal because the radiation utilized quickly dissipates below the skin, and the radiation effects on the internal organs are usually negligible. This case report describes a patient who underwent excision of a wide anterior neck keloid and received postoperative external beam radiation therapy of the incision. She presented with extensive upper airway edema, dyspnea, and dysphagia requiring readmission and steroids. Re-evaluation of the radiation protocol revealed an inadvertent intersection of the multiple abutting radiation fields at the supraglottic region, resulting in tripling of the dose in the area, and likely leading to her complication. She did well with conservative management with IV steroids, and did not require intubation. She has had no long-term sequelae and no recurrence at 6 months postoperative.

Abstract
BACKGROUND Keloid is a benign tumor with high recurrence rate; accordingly, complete surgical excision with adjuvant radiotherapy is one of the most effective treatments. This study reviewed outcomes of keloid patients receiving surgery and adjuvant radiotherapy in Kaohsiung Medical University Hospital. MATERIALS AND METHODS All patients received radiation dose with 15 Gy, with their first radiotherapy within 24 hours after surgical excision. The end points were recurrence rate and local recurrence-free interval (LRFI), defined clinically as palpable gross tumor over the treatment site and duration from the last day of radiotherapy to disease recurrence. RESULTS From May 2017 to July 2020, 32 patients with 40 keloid lesions were included. The mean age for these patients was 37.6 years, and the median follow-up time was 15.3 months. The overall recurrence rate was 52.5%, and the median LRFI was 9.7 months. Recurrence rates for males and females were 46.7% and 56% ( P = 0.567), respectively; for head and ear, chest, shoulder and upper extremities, and abdomen and back were 12.5%, 61.5%, 63.6%, and 62.5% ( P = 0.093); for lesions over 20 cm 2 and below 20 cm 2 were 62.5% and 50% ( P = 0.527); and for megavoltage electron beam and kilovoltage photon beam were 56.7% and 40% ( P = 0.361), respectively. Patients were further classified into 2 groups by lesion sites, which showed lower recurrence rate ( P = 0.011) and longer LRFI ( P = 0.028) with lesions over the head and ear than other sites. CONCLUSIONS We found that lesion site might be a prognostic factor for keloid recurrence. Adjuvant radiation dose escalation for high-recurrence risk areas (other than the head and ear) might be required.

Abstract
BACKGROUND Patients with chest keloids undergoing surgery and adjuvant radiotherapy still have a high recurrence rate, which is a critical problem. The level of keloid activity has not been studied, and a nomogram model for predicting keloid recurrence has not been established in previous studies. METHODS A total of 145 patients with chest keloids who underwent surgery and radiotherapy between January 2015 and January 2019 at Peking Union Medical College Hospital were included in our study. Demographic and clinical features and the score of KAAS were analyzed. We compared the area under the curve (AUC) and decision curve analysis (DCA) between KAAS and the Vancouver scar scale (VSS) and established a nomogram model for predicting the risk of recurrence. We used bootstrap and calibration plots to evaluate the performance of the nomogram. RESULTS The KAAS can predict recurrence in patients with chest keloids after surgery and radiotherapy. Areas under the curve (AUCs) of KAAS and VSS were 0.858 and 0.711, respectively (p < 0.001). Decision curve analysis (DCA) demonstrated that the KAAS was better than the VSS. Complications after treatment may be risk factors for keloid recurrence. We created a nomogram by using complications and KAAS. The AUC was 0.871 (95% CI 0.812-0.930). The ROC of the model's bootstrap was 0.865 and was well calibrated. CONCLUSIONS The KAAS can be used to predict the recurrence and we developed a nomogram for predicting the recurrence of chest keloids after surgery and adjuvant radiotherapy.

Abstract
Keloid is a common benign skin tumor in the outpatient department, and patients are often accompanied by itching and pain. Since the pathogenesis is unknown, the effect of single method treatment is unsatisfactory, and therefore the recurrence rate is high. Therefore, comprehensive treatment is mostly used in clinical treatment. Adjuvant radiotherapy is currently one of the most effective treatments for keloid. After long-term clinical practice, brachytherapy and electron beam radiotherapy has increasingly become the gold standard of treatment, because brachytherapy provides more focused radiation treatment to focal tissue to significantly reduce recurrence rate, and better preserve normal tissue. With the development of new radiotherapy techniques, more options for the treatment of keloid. Currently, adjuvant radiotherapy has been widely recognized, but there is no consensus on the optimal protocol for adjuvant radiotherapy for keloids. This review provides a review of published treatment options and new radiotherapy techniques for adjuvant radiotherapy of keloids and gives a comprehensive evaluation for clinical treatment.

Abstract
BACKGROUND Keloid is a type of benign tumor of the skin with abnormal proliferation of fibrous tissue. We sought to observe the changes in skin microcirculation and endothelial cell function around the recurred keloid and explore the skin microcirculation characters in recurred keloid patients. METHODS Six patients with recurred keloid were treated with keloid surgery and radiotherapy for the second time. Microcirculation of recurred keloids and their surrounding normal skin tissue was observed with laser Doppler flowmeter before operation. Expression of vascular endothelial growth factor (VEGF), CD31, and HIF-1α were identified by several assay. RESULTS The local blood flow of group RN was enhanced. The average strength of group N is 0.87. The average strength of group RN is 2.08. The expression of VEGF, CD31, and hypoxia inducible factor-1α (HIF-1α) protein in the keloid-recurred skin (RN) group was higher than the normal skin group via immunohistochemistry (IHC) and Western blotting analysis. The relative expression of VEGF and CD31 mRNA was significantly increased in RN group samples (P < .05). CONCLUSIONS There are significant differences in the expression of VEGF, CD31, and HIF-1α in the recurred keloid skin after radiotherapy and normal skin. They may be used as potential biomarkers and targets for future research on keloid recurrence.

Non-Oncological Radiotherapy: A Review of Modern Approaches. J Pers Med 2022; 12:jpm12101677. [PMID: 36294816 PMCID: PMC9605240 DOI: 10.3390/jpm12101677] [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: 09/22/2022] [Revised: 10/04/2022] [Accepted: 10/06/2022] [Indexed: 11/05/2022] Open
Abstract
Despite being usually delivered in oncological patients, radiotherapy can be used as a successful treatment for several non-malignant disorders. Even though this use of radiotherapy has been scarcely investigated since the 1950s, more recent interest has actually shed the light on this approach. Thus, the aim of this narrative review is to analyze the applications of non-oncological radiotherapy in different disorders. Key references were derived from a PubMed query. Hand searching and clinicaltrials.gov were also used. This review contains a narrative report and a critical discussion of non-oncological radiotherapy approaches. In conclusion, non-oncological radiotherapy is a safe and efficacious approach to treat several disorders that needs to be further investigated and used in clinical practice.

Abstract
Background: Keloid scars (KSs), which are composed of abnormal hyperplastic scar tissue, form during skin wound healing due to excessive fibroblast activation and collagen secretion. Although surgical resection and radiation therapy are used to prevent recurrence, KS recurrence rates range from 15 to 23%, and the underlying mechanism is unclear. Methods: To elucidate the mechanism of keloid recurrence, we established a PDX model and the grafts remained for over 20 weeks after transplantation on the bilateral backs of the NCG mice. Results: RNA-seq revealed that KS tissue gene expression was highly consistent before and after transplantation. Then, one side of the KS graft was irradiated with electron beam therapy (10 Gy), significant increases in vimentin and fibroblast activation protein alpha (FAP) expression were observed after irradiation and were accompanied by severe microvascular destruction. Surprisingly, 4 weeks after irradiation, significantly increased recurrence was observed with increased FAP + tissue and cell cycle regulator expression, resulting in a remarkable altered graft volume. Moreover, irradiation-induced FAP upregulation markedly facilitated radiation resistance and increased cell cycle progression, decreased senescence, and increased energy production. Conclusion: Our findings revealed that irradiation causes increased abundance of FAP + cells, which was associated with cell proliferation and delayed cellular senescence, accompanied by ATP production.

AAPS PharmSciTech 2022; 23:216.

Abstract
Hypertrophic scar is a serious skin disorder, which reduces the patient's quality of life. 5-aminolevulinic acid (5-ALA)-mediated photodynamic therapy has been used to treat patients with hypertrophic scar. However, the poor skin retention of 5-ALA limited the therapeutic effect. In this study, we constructed the 5-ALA-hyaluronic acid (HA) complex to potentially prolong the skin retention of 5-ALA for improving the therapeutic efficacy. HA is a polysaccharide with viscoelasticity and the carboxyl groups could conjugate with amino groups of 5-ALA via electrostatic interaction. The protoporphyrin IX (PpIX) assay revealed that 5-ALA-HA complexes markedly enhanced the skin retention, resulting in increased generation and accumulation of endogenous photosensitizer PpIX. Furthermore, 5-ALA-HA complexes allowed PpIX to be maintained at a high level for 12 h, much longer than the 3 h of 5-ALA alone. And then, the accumulative PpIX induced by 5-ALA-HA in human hypertrophic scar fibroblasts (HSF) was triggered by laser irradiation to produce sufficient reactive oxygen species, leading to efficient necrosis and apoptosis of HSF. In vivo therapeutic efficacy study indicated that 5-ALA-HA effectively reduced the appearance and scar thickness, and the scar elevation index with 5-ALA-HA treatment was significantly lower than other groups, suggesting that the 5-ALA-HA-treated scar became flattened and was closely matched to the unwounded tissues. Moreover, 5-ALA-HA treatment markedly downregulated the gene expression levels of α-SMA and TGF-β1, demonstrating attenuated the scar formation and growth. Therefore, the 5-ALA-HA complex enhancing skin retention and PpIX accumulation at the lesion site provide a promising therapeutic strategy for hypertrophic scar.

Abstract
Various treatments are available for auricular keloids, but none has an absolute advantage. A practical and safe therapy to optimize the surgical outcome for auricular keloids is needed. We adopted a multimodal treatment of surgical enucleation, core fillet flap reconstruction, intraoperative corticosteroid injection, and immediate postoperative radiotherapy. There were no routine intralesional corticosteroid injections during follow-up. Keloid recurrences, complications, and risk factors for recurrences were analyzed. The outcome was compared with other published literatures. 45 auricular keloids were included in this study. 85.7% were female with an average age of 27.1 ± 7.5 years, and averaged size was 1.8 × 1.2 ± 0.9 × 0.6 cm. 71.1% were located at ear helix with 28.9% at the ear lobe. Nine keloids were classified as Chang-Park classification type I, 30 for type II, two for type III, and four for IV. The average radiation dosage was 1578.6 cGy. The recurrence rate was 6.7% at an average 24.1-month follow-up. There were no complications of surgery, radiotherapy, and intralesional corticosteroid injection. Our recurrence rate was lower than those in mono-adjuvant therapies of intraoperative corticosteroid injection or radiotherapy. This one-session multimodal approach optimizes treating auricular keloids with a low recurrence rate and minimal post-radiation and long-term corticosteroid injection-related complications.

Abstract
Radiotherapy is one of the therapeutic methods for keloids, and the irradiation technique has innovated from superficial X-ray to brachytherapy after decades of clinical practice. At present, the application of adjuvant radiotherapy has been widely accepted by clinicians, while the consensus of optimal adjuvant radiotherapy strategies for keloids has not been reached. Factors such as radiation timing, dose, fractions, and lesion locations may be associated with the clinical outcomes of patients with keloids after radiotherapy while a comprehensive review is lacking. Herein, this review summarized the published literature of adjuvant radiotherapy for keloids involving mechanism, timing, dose, fractions, and complications, etc., which may facilitate clinical decision making.Level of Evidence III This journal requires that authors assign a level of evidence to each article.

Abstract
Purpose Keloids are caused by uncontrolled excessive proliferation of fibrous tissue. Multiple treatment strategies including steroid injection, surgical excision, laser therapy and radiation therapy have been reported. Few studies have evaluated the performance of plasma skin regeneration (PSR) in the treatment of keloid. This study aimed to evaluate the effectiveness of PSR combined with radiation therapy for keloids on different body parts. Patients and Methods A total of 71 patients with 98 keloids were enrolled in this study. Keloids <4 mm thick underwent single-dose PSR, while keloids ≥4 mm thick were administered compound betamethasone injection beforehand. Radiation therapy was administered after 24 hours and again 7 days later after PSR. The outcome was evaluated using the patient and observer scar assessment scale at 12 months post-treatment. Results Patient-reported average scores for all keloids significantly decreased from 35.05±9.94 to 21.84±7.04 (p < 0.05). Keloids on face and neck, chest, and back responded better than those on shoulders and limbs. The recurrence rate was observed to be 15.3% (15 out of 98). Adverse effects were mild. Conclusion PSR combined with radiation therapy is an effective and safe strategy to treat keloids. Location could be a factor that affects curative effects.

Abstract
Keloids are a benign fibroproliferative disease with a high tendency of recurrence. Keloids cause functional impairment, disfigurement, pruritus, and low quality of life. Many therapeutic options have been used for keloids. However, the high recurrence rates have led to the use of adjuvant therapy after surgical keloid excision. There are different radiotherapy regimens available, and the advantages and disadvantages of each are still unclear. The aim of this review is to explain the appropriate radiotherapy regimen for keloids as well as discuss the recent reports on keloid management with radiotherapy. Adjuvant radiotherapy after surgical excision for keloids yields excellent local control with tolerable side effects. Hypofractionated radiotherapy with a BED of more than 28 Gy (α/β value of 10) after excision is recommended in the light of its biologic background.

Abstract
Scars vary from mature linear scars to abnormal excessive scars such as hypertrophic scars and keloid scars. Keloid scars are fibro-proliferative disease entities that reflect an abnormal process of wound healing. They can cause pain, itching, stiffness, and psychological distress, all of which can affect quality of life. Various treatment options have been advocated as ways to prevent and treat keloid scars. These include noninvasive treatments such as use of silicone gel sheeting and compression therapy, and invasive treatments such as intralesional corticosteroid injections, surgery, and radiotherapy. Novel treatments include chemotherapy, immunotherapy, and anti-inflammatory therapies. Unfortunately, keloids continue to pose a significant challenge due to the lack of efficacious treatments. Therefore, clinicians should be familiar with various therapeutic options and apply the most suitable treatment plan for patients. In this review, we introduce the current therapeutic options for the management of keloid scars.

Abstract
At present, the consensus on the best treatment for keloids is the combination of clinical and surgical therapies, if necessary, associated with adjuvant radiotherapy like brachytherapy. Whereas, the uniform scheme of radiotherapy in keloids is unclear. Here, we conducting a retrospective analysis to assess the efficacy and safety of a specific treatment regimen (20 Gy in 5 fractions) in keloid patients. We retrospectively analysed the medical records of keloid patients receiving auxiliary postoperative radiotherapy (PORT) treatment from 2009 to 2019. The patients were treated with the hypofractionation method of 20 Gy in 5 fractions. We compared the local control rate and complications, using the chi-square test and logistic regression analyses. After screening, we identified 100 keloid patients in this study, with a median follow-up of 59 months. In this study, the overall local control rate of keloid lesions was 84.8%. After multivariate analyses (primary keloid or not, family history, interval from surgery to irradiation and site), our research showed that primary keloid, site and interval from surgery to irradiation were significantly related to recurrence. Acute radiation injury and late radiation injury accounted for 3% (erythema) and 1% (skin sclerosis) of the total cases, respectively. Our results indicate that a postoperative hypofractionation with radiation dose of 20 Gy in 5 fractions may be effective, easy to accept and safe for keloid patients.

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
PURPOSE To assess the efficacy and toxicity of hypofractionated radiotherapy (RT) alone in treatment-resistant symptomatic keloids. METHODS Six patients with a total of 13 inoperable large keloid lesions and no response to previous treatments were admitted to our department between 2017 and 2019. All patients were examined for detailed wound localization, size, contour, and color assessment, and for objective and subjective symptoms. Response to treatment was graded as "complete remission" in case of full symptomatic relief and >75% decrease in lesion size, as "partial remission" in case of partial symptomatic relief and 25-75% decrease in lesion size, and as "stable disease" in case of no symptomatic relief or <25% decrease in lesion size. Patients were followed up monthly for the first 3 months and every 3 months thereafter by physical examination. RESULTS A total dose of 37.5 Gy external RT in five fractions was prescribed by 6‑MeV electrons in 4 patients and 6‑MV photons in 2 patients. Complete response was obtained in all patients at the 6‑month control. All patients were satisfied with cosmetic results at their last control. Grade 2 dermatitis developed in all patients during the second week of RT but resolved completely in all after 6 months following the end of RT. CONCLUSION In keloids that are unresponsive to standard treatment, hypofractionated RT using a total dose of 37.5 Gy in five fractions is feasible.

Abstract
Keloids are a fibroproliferative disorder that can result from a cutaneous injury to the reticular dermis. Recurrence rates as high as 100% have been reported following surgical excision alone. Consequently, a variety of post-surgical techniques have been employed to prevent keloid recurrence, including the use of radiation. Although numerous studies have shown post-excisional X-rays, electron beam, lasers and brachytherapy can reduce the rate of keloid recurrence, numerous inconsistencies, including a wide range of definitions for keloid recurrence, make it difficult to compare study outcomes. The review aims to examine the various means for defining keloid recurrence in clinical trials involving the use of radiation therapy. Searches of the Cochrane Library and PubMed were performed to identify the available information for post-surgical keloid recurrence following radiation therapy. Each identified study was reviewed for patient follow-up and criteria used to define keloid recurrence. The search results included clinical studies with external beam radiation, brachytherapy and superficial radiation therapy. Many studies did not include a definition of keloid recurrence, or defined recurrence only as the return of scar tissue. Other studies defined keloid recurrence based on patient self-assessment questionnaires, symptoms and scar elevation and changes in Kyoto Scar Scale, Japan Scar Workshop Scale and Vancouver Scar Scale scores. The results of this review indicate keloidectomy followed by radiation therapy provide satisfactory recurrence rates; however, clinical studies evaluating these treatments do not describe treatment outcomes or use different definitions of keloid recurrence. Consequently, recurrence rates vary widely, making comparisons across studies difficult. Keloid recurrence should be clearly defined using both objective and subjective measures.

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.

Risk factors of recurrence after postoperative electron beam radiation therapy for keloid: Comparison of long-term local control rate. Rep Pract Oncol Radiother 2020; 25:606-611. [PMID: 32523428 DOI: 10.1016/j.rpor.2020.05.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 03/25/2020] [Accepted: 05/06/2020] [Indexed: 11/17/2022] Open
Abstract
Aim To investigate the new risk factors for keloid recurrence after postoperative electron beam radiotherapy (RT) and evaluate the effectiveness of tranilast in combination with electron beam RT by comparing the local control rate. Background Identifying patients at high risk of recurrence after postoperative RT for keloids remains a challenge. Besides, no study examined the effectiveness of tranilast in combination with RT after surgery for the prevention of keloids recurrence. Materials and Methods This study included 75 lesions in 59 consecutive patients who had undergone postoperative RT at our institute. The follow-up period and prescription of tranilast were examined beside several potential risk factors, such as multiple lesions, size, and shape. Results The median follow-up was 72 months (range, 6-147 months). Twenty-one lesions in 17 patients recurred in a median of 12 months after treatment (range, 1-60 months). Local control rates of all 75 lesions were estimated as 93%, 78%, 70%, and 68% at 1, 2, 5, and 10 years. Multiple lesions constituted a significant risk of recurrence (P = 0.03). A larger long axis was significantly related to the recurrence (P < 0.01). Irregular shape was associated with a significantly worse local control rate (P = 0.02). There was no significant difference in the local control rate between patients receiving tranilast and those who did not (P = 0.52). Conclusions Multiple lesions and irregular shape were risk factors of keloid recurrence after postoperative electron beam RT. The effectiveness of tranilast was not demonstrated in the study.

Inhibition of microRNA-21-5p reduces keloid fibroblast autophagy and migration by targeting PTEN after electron beam irradiation. J Transl Med 2020; 100:387-399. [PMID: 31558773 DOI: 10.1038/s41374-019-0323-9] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 08/14/2019] [Accepted: 08/22/2019] [Indexed: 01/17/2023] Open
Abstract
Electron beam (EB) irradiation is useful to reduce the recurrence of keloids; however, the underlying mechanism remains unknown. MicroRNA-21 (miR-21), which regulates autophagy during cancer radiation therapy, was identified as a potential therapeutic target for keloids. Here, we investigate the regulatory mechanism(s) of miR-21-5p on keloid fibroblast autophagy and migration after EB irradiation. The microRNA expression profile of the keloid dermis was examined by performing a microRNA microarray. Levels of LC3B and Beclin-1 were detected by immunohistochemical and western blot analysis in the keloid dermis and fibroblasts. Autophagy and apoptosis were tested in keloid fibroblasts after EB irradiation or transfection with an miR-21-5p inhibitor using electron microscopy, a Cyto-ID Green Autophagy Detection Kit, and an Annexin V PE Apoptosis Detection Kit. Migration was analyzed by an in vitro scratch-wound healing assay. Mechanistic tests were performed using small interfering RNAs to phosphatase and tensin homolog (siPTEN). Levels of miR-21-5p, PTEN, programmed cell death 4 (PDCD4), p-AKT, and apoptosis- and autophagy-associated genes were examined by qRT-PCR and western blotting. LC3B expression and migration ability were enhanced in fibroblasts and the keloid margin dermis compared with those in the adjacent normal skin. Both EB irradiation and an miR-21-5p inhibitor reduced keloid fibroblast autophagy, which was accompanied by decreased expression of miR-21-5p, p-AKT, and LC3B-II and increased expression of PTEN, PDCD4, and apoptosis-related genes. MiR-21-5p downregulation inhibited migration and suppressed LC3B expression and this was reversed by PTEN reduction. In conclusion, with increasing apoptosis, EB irradiation inhibits autophagy in keloid fibroblasts by reducing miR-21-5p, which regulates migration and LC3B expression via PTEN/AKT signaling. These data suggest a potential mechanism wherein miR-21-5p inhibition regulates autophagy and migration in EB-irradiated keloid fibroblasts, effectively preventing local invasion and recurrence. Therefore, miR-21-5p could be a new therapeutic target, to replace EB irradiation, and control keloid relapse.

Pediatric earlobe keloids: Outcomes and patterns of recurrence. J Pediatr Surg 2020; 55:461-464. [PMID: 31383580 DOI: 10.1016/j.jpedsurg.2019.07.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Revised: 06/23/2019] [Accepted: 07/15/2019] [Indexed: 11/21/2022]
Abstract
PURPOSE Keloids occur as a result of abnormal wound healing and as many as 70% of keloids and hypertrophic scars affect the pediatric population. Earlobe keloids, similar to lesions elsewhere in the body, remain a challenging problem given the high rates of recurrence and lack of consensus regarding treatment strategy. This study aims to evaluate the outcomes and patterns of recurrences following treatment of earlobe keloids in a large cohort of pediatric patients to facilitate identification of the optimal treatment strategy. METHODS All pediatric patients who underwent surgical therapy for earlobe keloids over a 10-year period (2004-2015) were identified and demographic, clinical and outcomes data were collected. A follow-up phone survey was administered to assess rates of long-term recurrence and overall satisfaction with the treatment strategy. Data analysis was performed using Student's t-test and Fisher's exact as appropriate. RESULTS A total of 94 patients with 135 keloids were identified. Mean age was 14 years with slight preponderance of females (52%) and a majority (75%) of the patients were African American (AA). Mean keloid size was 2.4 cm (0.25-11 cm) with ear piercing being the most common inciting etiology. Excision with steroid injection (59%) was the most frequent treatment approach followed by excision alone (25%). During a median follow up of 2 years, keloid recurrence occurred in 27 (28.7%) patients, 19 (70.4%) underwent additional therapy with 10 (52.6%) re-recurrences noted. Median time to recurrence was 23 months, with a slightly higher recurrence rate in AA patients (32%; p = 0.26) and in those age < 10 years (50%; p = 0.11). CONCLUSION This represents the largest series of earlobe keloids treatment in children. Our data suggest that recurrence rates are unaffected by the age at excision and race of the patient. Moreover, adjuncts to excisional therapy such as steroid injection, compression therapy and radiation also did not appear to influence recurrence. Given the pattern of recurrences studies with longer term follow-up are needed to assess the efficacy of treatment strategies. TYPE OF STUDY Case series. LEVEL OF EVIDENCE IV.

Abstract
Objective: Keloid patients usually have local pruritus and pain. In our clinical work, we have found keloid patients after receiving hyperbaric oxygen (HBO) therapy reflect less pruritus and pain. The hypothesis was that patients with keloid and a history of HBO therapy would have less pruritus and pain than patients without HBO therapy, and the pruritus or pain-related factors were detected in keloid with/without HBO therapy and normal skin. Methods: Three groups of samples were established: keloid samples from patients with HBO therapy for two weeks before and after surgery (H group); keloid samples from patients without HBO therapy (G group); normal skin samples from patients without obvious scar (N group). Hematoxylin and eosin (H&E) staining was used to observe morphological changes. Pruritus/pain related factors: Tryptophan Hydroxylase1 (TPH1), connexin-43 (Cx43) and transient receptor potential vanilloid type 1 (TRPV1) were detected by immunofluorescence and western blot technology. The expression of these factors' mRNA was also measured by the real-time quantitative polymerase chain reaction (RT-qPCR). Results: Among three groups, G group presented significantly highest expression levels of TPH1, Cx43 and TRPV1, conversely, N group presented significantly lowest expression levels of TPH1, Cx43 and TRPV1. Conclusion: TPH1, Cx43 and TRPV1 were overexpressed in the samples of keloid patients, indicating that the pruritus and pain of keloid might be related to these factors. Furthermore, TPH1, Cx43 and TRPV1 were expressed highest in keloid patients without HBO therapy, indicating that HBO therapy might relief pruritus of keloid patients by regulating these factors.

Abstract
OBJECTIVE To demonstrate that superficial high-dose-rate (HDR) brachytherapy by means of Leipzig applicators or moulds with catheters is an adjuvant treatment with impact on local control and low toxicity. BACKGROUND Keloid scars occur in 5-15 % of cases, secondary to an uncontrolled proliferation of fibroblasts and reduction in the inhibition of growth factors. MATERIAL AND METHODS Retrospective, longitudinal and descriptive study in patients with keloid scars who were treated with superficial HDR brachytherapy in the General Hospital of Mexico between November 2009 and December 2013. RESULTS Eighty patients were evaluated, and the mean follow-up was 22.18 months (range 8-48). The anatomic site treated was the ear in 72 patients (90.0 %), anterior thorax in 5 patients, retroauricular region in 2, and abdomen region in 1 patient. The application was performed 24 h after surgery; the dose for 79 patients (99 %) was 1500 cGy/3 fractions, and 1 received 500 cGy in 1 fraction. Adequate healing occurred in 76 patients (95 %), and the local failure was 5 % (95 % CI). Acute toxicity occurred in 15 % (12 patients) with grade 1 radioepithelitis. Chronic toxicity occurred in 22 patients (27.5 %) with grade 1 hypopigmentation and 18 patients (22.5 %) with grade 1 fibrosis. The cosmetic result was good in 72 patients (90 %). During follow-up, 2 patients presented recurrence, and 2 patients persisted. CONCLUSIONS Treatment with superficial brachytherapy in keloid scars using a mould with catheters or a Leipzig applicator is a therapeutic option that results in 95 % local control and low toxicity.

Abstract
Keloids are pathological scars that grow over time and extend beyond the initial site of injury after impaired wound healing. These scars frequently recur and rarely regress. They are aesthetically disfiguring, can cause pain, itching, discomfort as well as psychological stress, often affecting quality of life. Many treatment modalities, including surgical and non-surgical, have been explored and have been reported to be beneficial; however, none have been absolutely satisfactory or optimal for the treatment of all keloid subtypes to date. This poses a major challenge to clinicians. Often, a combinational therapeutic approach appears to offer the best results with higher patient satisfaction compared to monotherapy. The aetiopathogenesis of keloids is not fully elucidated; however, with recent advances in molecular biology and genetics, insight is being gained on the complex process of scar formation and hence new therapeutic and management options for keloids. In this paper, we explore the literature and summarise the general concepts surrounding keloid development and review both current (corticosteroids, surgical excision, silicone-based products, pressure therapy, radiotherapy, cryotherapy, laser therapy, imiquimod and 5-fluorouracil) and emerging (stem cell therapy, mitomycin C, verapamil, interferons, bleomycin, botulinum toxin type A and angiotensin-converting enzyme inhibitors) treatments. Increased knowledge and understanding in this area may potentially lead to the discovery and development of novel therapeutic options that are more efficacious for all keloid types. LAY SUMMARY Keloids are problematic scars that are difficult to treat and manage. The aetiopathogenesis of keloids is not clear; however, recent advances in molecular biology and genetics are beginning to shed light on the underlying mechanisms implicated in keloid scar formation which will hopefully lead to the development of treatment options for all keloid types. This review summarises current and emerging therapies.

Abstract
Keloids are caused by an imbalance between collagen matrix decomposition and
production during wound repair. Spontaneous keloids are a rare type of keloid
that arise without a significant history of trauma or surgery. We herein report
a case involving a 59-year-old woman with symmetric neoplasms at the bilateral
labia majora that had persisted for about 3 years and a >10-year history of
pruritus and pain at the bilateral labia majora with folliculitis. The bilateral
labia majora gradually swelled and lost their normal physiological morphology.
The patient was diagnosed with keloids. Under general anesthesia, the keloids
were resected. The right incision was sutured directly and the left was closed
using an inguinal flap. Adjuvant radiotherapy was administered after the
surgery. No recurrence of the keloids was observed at the 1-year follow-up, and
the patient was satisfied with the appearance of the vulvar region. This is the
first report of spontaneous symmetrical giant keloids at the bilateral labia
majora, and it emphasizes the importance of the effect of abnormal inflammation
on keloid formation. Repairing genital defects using an inguinal flap has only a
minor effect on the patient’s postoperative movement, and an ideal vulvar
appearance can be achieved.

Abstract
Although the use of ionizing radiation on malignant conditions has been well established, its application on benign conditions has not been fully accepted and has been inadequately recognized by health care providers outside of radiation therapy. Most frequently, radiation therapy in these benign conditions is used along with other treatment modalities, such as surgery, when the condition causes significant disability or could even lead to death. Radiation therapy can be helpful for inflammatory/proliferative disorders. This article discusses the present use of radiation therapy for some of the most common benign conditions.

Abstract
RATIONALE Micro-plasma radio-frequency (MPR) technology has been demonstrated a safe and effective treatment for kinds of scars, but there is no report about the application of the MPR on keloids. In this investigation, we creatively use MPR technology combining with hypofractionated electron-beam radiation to cure keloids. PATIENT CONCERNS AND DIAGNOSES From February 2013 to December 2016, 22 Asian patients (16 male, 6 female, age 19-46 years, mean age 28.14 ± 7.31 years) with keloids over half a year were enrolled in this study. INTERVENTIONS AND OUTCOMES All patients received a single MPR technology treatment by roller tip at 80-100 watt, and then hypofractionated electron-beam radiation of 6 MeV were performed twice, within 24 hours and one week after the operation with 9 Gy per time. Improvement were determined by the Vancouver Scar Scales (VSS) according to digital photographs. The results show that the volume of keloids reduced significantly among most patients. Only 3 patients encountered with mild to moderate hyperpigmentation, and none of malignance and worsening or recurrence of scars was observed. LESSONS MPR technology combined with post-operative hypofractionated electron-beam radiation therapy is an effective method for patients with multiple keloids distributed widely on the body with minimal complications, especially for patients with widely distributed keloids.

Abstract
Skin is the largest organ of the human body. Being the interface between the body and the outer environment, makes it susceptible to physical injury. To maintain life, nature has endowed skin with a fast healing response that invariably ends in the formation of scar at the wounded dermal area. In many cases, skin remodelling may be impaired, leading to local hypertrophic scars or keloids. One should also consider that the scarring process is part of the wound healing response, which always starts with inflammation. Thus, scarring can also be induced in the dermis, in the absence of an actual wound, during chronic inflammatory processes. Considering the significant portion of the population that is subject to abnormal scarring, this review critically discusses the state-of-the-art and upcoming therapies in skin scarring and fibrosis.

Retrospective study of immediate postoperative electron radiotherapy for therapy-resistant earlobe keloids. Arch Dermatol Res 2019; 311:469-475. [PMID: 31041525 PMCID: PMC6594988 DOI: 10.1007/s00403-019-01922-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 02/25/2019] [Accepted: 04/13/2019] [Indexed: 11/17/2022]
Abstract
Keloid resection followed by adjuvant radiotherapy is the most efficacious treatment for keloids. However, for earlobe keloids, an optimal protocol for the total dose and fractions of adjuvant radiation has not yet been established. We retrospectively analyzed the efficacy and safety of immediate three-fraction electron radiotherapy after operation for resistant earlobe keloids. From 2011 to 2017, three-fraction electron radiotherapy with single dose of 5 Gy was given postoperatively to 23 patients with 30 keloids in our hospital. The first fraction of adjuvant radiotherapy was administered within 2 h of surgery, and the other two sessions were completed within the next day or two. Five (16.7%) primary keloids and 25 (83.3%) recurrent keloids were examined in this study. The primary endpoint was the local control rate, which was 86.7% after a median follow-up of 26 months (14–93 months). Secondary endpoints were acute and late procedure-related complications, and no severe complications were observed after combination therapy. Our results suggest that three-fraction electron radiotherapy after excision within 2 days of surgery is a safe and effective protocol for the prevention of earlobe keloid recurrence that can also improve patient compliance and comfort.

Abstract
Background: The use of superficial radiation therapy (SRT) has experienced a renaissance for treating nonmelanoma skin cancers (NMSCs) and recurrent keloids; however, published treatment guidelines are lacking. Objective: The objective of this work was to provide consensus guidelines on the use of SRT for treating NMSC and recurrent keloids based on a review of the literature and expert opinion. Methods and Materials: A search of the medical literature was performed to obtain published information on the use of SRT for review. A group of qualified dermatologists convened to discuss their views on the use of SRT for the treatment of NMSCs and recurrent keloids. The various guidelines were considered to have consensus based on a supermajority two-thirds vote. The final consensus guidelines are thus based on the medical literature, when available, and expert opinions. Results: Agreement on consensus guidelines was reached for numerous aspects of SRT use, including appropriate tumor types for SRT; anatomical areas suitable for SRT; energy, fractions, and scheduling recommendations for SRT; use of SRT in the presence of comorbidities; safety factors; and treatment recommendations for recurrent keloids, based the literature and on both the opinions of the expert group and a survey of experienced users. Conclusion: Consensus was reached that SRT is a safe and effective treatment for basal cell and squamous cell carcinomas and should be considered as the first-line form of radiation treatment. Postsurgical treatment of keloid excision suture lines with SRT significantly reduces keloid recurrence rates.

Abstract
The aim of this study is to report an uncommon case of nasal keloid treated with adaptive image-guided high-dose-rate (HDR) intracavitary brachytherapy. A 34-year-old female presented with nasal keloid after facial trauma was treated with scar resection and HDR intracavitary brachytherapy with a customized eccentric applicator. The total dose was 21 Gy in 6 fractions. During 3 years of follow-up, there was no evidence of recurrence at the local site, and no complications. In conclusion, HDR intracavitary brachytherapy is an effective way to prevent the recurrence of nasal keloids post-surgery.

Abstract
PURPOSE Surgical excision of keloids can result in an insidious cycle of tissue injury and repeat keloid formation unless combined with adjuvant therapy to halt this cycle. We present our results of postoperative radiation therapy for keloids with various dose regimens. METHODS AND MATERIALS A retrospective review of 124 patients with 250 keloid lesions treated with postoperative radiation therapy was analyzed. In this institutional review board-approved study, 125 keloids were treated to 20 Gy in 5 fractions and 125 keloids were treated to 12 to 16 Gy in 3 to 4 fractions. Local failure was defined as redevelopment of any clinically apparent keloid at the treated site. The median age was 34 years (14-84 years). Keloids were located on the ear (34%), neck/shoulder (19%), abdomen (13%), chest (10%), face (9%), breast (7%), extremities (4%), and back (3%). Median keloid size was 4 cm (0.5-20 cm). RESULTS At a median follow-up of 40 months, the recurrence rate for all lesions was 5.6%. Lesions treated to 20 Gy had a recurrence rate of 1.6% compared with 9.6% with <20 Gy and an odds ratio of 0.16 (P = .02). Upon univariate and multivariate analysis there were no differences in recurrence rate with respect to location, race, gender, age, previously treated lesions, and presence of multiple keloids. The lone predictor for improved control rate was the dose of 20 Gy in 5 fractions compared with less than that. Control rate for lesions treated to a biologically equivalent dose2 of 35 to 36 Gy2, 48 to 52.5 Gy2, and 60 to 72 Gy2 were 10% (P = .007), 8.9% (P = .16), and 1.6% (P = .02), respectively. CONCLUSIONS Surgical excision followed by immediate adjuvant radiation therapy for keloids provides excellent local control and cosmesis. Treatment with a biologically equivalent dose2 > 60 (20 Gy in 5 fractions) yielded superior local control over lower dose regimens.

Abstract
Objective: Radiation therapy combined with surgical excision was considered as one of the most effective treatment plans for keloid lesions. However, there was no unanimity found over present literatures regarding the issue on optimized treatment strategy for keloids. We here provide a comprehensive review over this issue and emphasize on the influencing factors. Data Sources: The data analyzed in this review were searched from articles included in PubMed and EMBASE databases. Study Selection: The original articles and critical reviews discussing the application of radiation therapy in keloids treatment were selected for this review. Results: The application of radiation therapy has transitioned from simple superficial X-ray irradiation to brachytherapy. Furthermore, several factors including radiation type, dose, fraction, interval, and complications were reviewed, and the results revealed that these factors were significant toward clinical outcome at various levels. Conclusions: Both past and present evidence support the idea that combination therapy of radiation and surgical therapy is safe and feasible. However, the optimization of treatment strategy was based on different radiation types and should take dose, fractions, interval, and complications into consideration, which will then decrease the rate of recurrence and increase the level of satisfaction.

Abstract
Hypertrophic scars and keloids are fibroproliferative disorders that may arise after any deep cutaneous injury caused by trauma, burns, surgery, etc. Hypertrophic scars and keloids are cosmetically problematic, and in combination with functional problems such as contractures and subjective symptoms including pruritus, these significantly affect patients’ quality of life. There have been many studies on hypertrophic scars and keloids; but the mechanisms underlying scar formation have not yet been well established, and prophylactic and treatment strategies remain unsatisfactory. In this review, the authors introduce and summarize classical concepts surrounding wound healing and review recent understandings of the biology, prevention and treatment strategies for hypertrophic scars and keloids.

Abstract
BACKGROUND: Radiotherapy has been used historically to treat a wide variety of dermatologie conditions, including nonmelanoma skin cancers, lymphomas, and inflammatory skin conditions. Recently, radiotherapy has been used increasingly as a valuable tool in the postsurgical treatment of large or recalcitrant keloids. OBJECTIVE: The objective of this review was to explore the use of radiation therapy as an adjuvant to surgically excised keloids. DESIGN: A PubMed search of all published English literature regarding the applications of radiotherapy for the treatment of keloids was performed using a combination of keywords including radiation, radiotherapy, brachytherapy, electron beam, superficial radiation, orthovoltage radiation, and keloid. The results were analyzed and collated. RESULTS: A comprehensive review of radiotherapy for the adjuvant treatment of keloids was outlined. CONCLUSION: Radiotherapy appears useful as an adjuvant therapy to surgically excised keloids. Dermatologists should be well versed in radiotherapy to provide optimal care for patients with recalcitrant keloids.

Abstract
BACKGROUND Keloid and hypertrophic scars represent an aberrant response to the wound healing process. These scars are characterized by dysregulated growth with excessive collagen formation, and can be cosmetically and functionally disruptive to patients. OBJECTIVE Objectives are to describe the pathophysiology of keloid and hypertrophic scar, and to compare differences with the normal wound healing process. The classification of keloids and hypertrophic scars are then discussed. Finally, various treatment options including prevention, conventional therapies, surgical therapies, and adjuvant therapies are described in detail. MATERIALS AND METHODS Literature review was performed identifying relevant publications pertaining to the pathophysiology, classification, and treatment of keloid and hypertrophic scars. RESULTS Though the pathophysiology of keloid and hypertrophic scars is not completely known, various cytokines have been implicated, including interleukin (IL)-6, IL-8, and IL-10, as well as various growth factors including transforming growth factor-beta and platelet-derived growth factor. Numerous treatments have been studied for keloid and hypertrophic scars,which include conventional therapies such as occlusive dressings, compression therapy, and steroids; surgical therapies such as excision and cryosurgery; and adjuvant and emerging therapies including radiation therapy, interferon, 5-fluorouracil, imiquimod, tacrolimus, sirolimus, bleomycin, doxorubicin, transforming growth factor-beta, epidermal growth factor, verapamil, retinoic acid, tamoxifen, botulinum toxin A, onion extract, silicone-based camouflage, hydrogel scaffold, and skin tension offloading device. CONCLUSION Keloid and hypertrophic scars remain a challenging condition, with potential cosmetic and functional consequences to patients. Several therapies exist which function through different mechanisms. Better understanding into the pathogenesis will allow for development of newer and more targeted therapies in the future.

Abstract
Background The high recurrence rate following keloid resection has generated interest in adjuvant treatments for this disease. Objective This study assesses keloid recurrence when treated with surgery and adjuvant radiotherapy. Methods Retrospective analysis of resected keloids in patients referred to a Chilean radiation oncology centre between 2006 and 2013. Local recurrence was defined as new tissue growth on the surgical scar margin. Results Around103 keloids were analysed in 63 patients treated with 15 Gy in three fraction radiotherapy which was initiated on the same day as the surgery (75% of cases). The median keloid diameter was 6 cm; the most common site was thoracic (22%); the most common cause was prior surgery (35%); 37% caused symptoms, and several (47%) had received prior treatment with corticosteroids (32%), or surgery (30%). The median follow-up was three years, and 94% of recurrences occurred during the first year following treatment. Uni and multivariate analyses showed that an absence of symptoms was a protective factor for recurrence (OR: 0.24), while the time interval from onset to treatment with surgery plus radiotherapy >4.2 years was a risk factor (OR: 2.23). The first year recurrence rate was 32% and stabilised at 32% by the second year with no recurrences after 15 months. Conclusions The combination of surgery and radiotherapy proved to be a good therapeutic alternative in the management of keloids. Our results are similar to those described in the literature for a dose of 15 Gy. Given these results, our centre will implement a new dose escalation protocol to improve future outcomes.
