RESUMO

PURPOSE: Radiation-induced skin reactions remain one of the most frequent side effects of adjuvant radiotherapy for breast cancer, which is the most common global malignancy. In individual cases, we observed a decrease in radiation dermatitis under film dressings used for skin marking purposes. Therefore, we decided to revise the available evidence regarding the prophylactic use of film dressings to reduce radiation dermatitis in breast cancer patients. METHODS: On 20 March 2023, we conducted a systematic review of literature for randomized controlled trials published in the English, German, French, or Spanish language, available in the PubMed database. RESULTS: Of 82 publications, 9 full texts were assessed and 6 randomized controlled trials were included in the final synthesis. Two trials analyzed the application of polyurethane film (Hydrofilm, Paul Hartmann AG, Heidenheim, Germany), the other four of silicone-based polyurethane film (Mepitel film, Molnlycke Health Care Limited, Milton Keynes, United Kingdom). The evaluation scales Common Terminology Criteria for Adverse Events (CTCAE), Radiation Therapy Oncology Group (RTOG), and the Radiation-Induced Skin Reaction Assessment Scale (RISRAS) were used for assessment. All six trials, with a total of 788 patients yielding data for analysis, demonstrate a significant decrease in radiation-induced skin reactions by use of the film (mainly p < 0.001). CONCLUSION: Our analysis demonstrates a significant decrease in radiation-induced skin reactions by prophylactically applied film dressings in breast cancer patients. Consequent preventive use of film dressings might systematically reduce acute radiation-induced skin reactions in these patients.

RESUMO

PURPOSE: To evaluate the overall efficacy of StrataXRT, a topical gel dressing, in preventing acute radiation dermatitis (RD) in breast cancer patients undergoing radiotherapy (RT). METHODS: A systematic search was conducted on April 25, 2023 in Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) assessing the effectiveness of StrataXRT in preventing acute RD in breast cancer patients undergoing adjuvant RT to the breast or chest wall with or without regional nodes were included. Pooled incidence odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model, with analysis and forest plots generated in RevMan v5.4. RESULTS: The analysis included three RCTs with a total of 189 patients assessed using per-protocol analysis. Two RCTs compared StrataXRT to standard of care, while the third compared it with Mepitel film and was reported separately. In the former RCTs, the odds ratio (OR) for developing acute grade 3 RD favored StrataXRT at 0.05 (95% CI, 0.01-0.22; P < 0.0001). The OR for developing acute grades 2-3 RD was 0.32 (95% CI, 0.03-3.18; P = 0.33). The RCT comparing StrataXRT with Mepitel film showed insignificant ORs for grade 3 and grades 2-3 RD. One RCT reported significantly lower erythema index (P = 0.008) and melanin index (P = 0.015) in StrataXRT patients. The use of StrataXRT did not raise additional safety concerns. CONCLUSION: StrataXRT may help prevent severe acute RD in breast cancer RT patients. Further high quality, large-scale studies are needed to confirm these findings.

RESUMO

PURPOSE: This systematic review and meta-analysis aimed to evaluate the efficacy of Mepitel film in preventing or treating acute radiation dermatitis (RD) in patients with breast cancer in randomized controlled trials (RCTs). METHODS: Embase, APA PsychInfo, Journals@Ovid Full Text, Ovid MEDLINE, PubMed, and Cochrane Trials were searched until December 12, 2022, to identify RCTs on the use of Mepitel film for preventing or treating acute RD from breast cancer radiotherapy. Per-protocol analysis was used to compare outcomes, calculate pooled effect sizes, odds ratio (OR), and 95% confidence intervals (CI), and to create forest plots using random effects analysis in RevMan 5.4. RESULTS: Three RCTs were included in this review. Mepitel film significantly reduced the incidence of grade 3 RD (OR 0.15 95% CI 0.06, 0.37, p<0.0001) and grade 2 or 3 RD (OR 0.16 95% CI 0.04, 0.65, p=0.01) as scored on either the CTCAE or the RTOG scale. Additionally, Mepitel film significantly reduced RISRAS mean scores assessed by patients and combined researcher and patient (standardized mean difference (SMD) -7.59, 95% CI -14.42, -0.76, p=0.03; SMD -15.36, 95% CI -30.01, -0.71 p=0.04) but not the researcher component of the assessment tool (SMD -17.55, 95% CI -36.94, 1.84, p=0.08). CONCLUSION: Mepitel film reduced the incidence of acute RD and improved patient-reported outcomes with minimal side effects, the main one being itchiness. Future research should assess the feasibility of Mepitel film with respect to specific patient-reported outcomes such as health-related quality of life issues associated with its use.

RESUMO

PURPOSE: Radiation-induced skin injury represents one of the most common side effects in breast cancer patients receiving adjuvant whole-breast radiotherapy. Numerous systemic and topical treatments have been studied in the prevention and management of radiation-induced skin injury without providing sustainable treatment strategies. While superficial barrier-forming skin products such as dressings are the standard of care in wound care management, their utilization as preventive treatment approach in radiotherapy has barely attracted attention. METHODS: In this prospective, intra-patient randomized study, Hydrofilm polyurethane film dressings were applied prophylactically to either the medial or lateral breast half of 62 patients with breast cancer undergoing adjuvant radiation therapy following breast conserving surgery. The breast half contralateral to the film dressing was concurrently treated with 5% urea lotion as control skin care. Maximum severity of radiation dermatitis was assessed using RTOG/EORTC toxicity scores, photospectrometric erythema measurements and patient-assessed modified RISRAS scale. RESULTS: In the Hydrofilm compartments, mean maximum RTOG/EORTC radiation dermatitis severity grades were significantly reduced from 1.33 to 0.35 and photospectrometric measurements showed significantly reduced erythema severity, as compared to the control compartments, with an overall response rate of 89.3%. Hydrofilm completely prevented moist desquamation and significantly reduced patients' subjective experience of itching and pain. CONCLUSION: The obtained results along with a favorable cost-benefit ratio and an easy and quick application suggest a prophylactic application of Hydrofilm in adjuvant radiotherapy of breast cancer patients to reduce or even prevent radiation dermatitis.

RESUMO

Psychological stress exacerbates many pathological conditions including inflammatory skin conditions. The effect of psychological stress on acute radiation-induced skin reactions has not been documented before. Here, we aimed to explore if psychological stress could aggravate skin reaction severity in breast cancer patients. We conducted a secondary analysis of patient data obtained during a randomised, controlled clinical trial for acute radiation-induced skin reaction severity in 78 breast cancer patients. Patients were assessed three times a week during treatment. Skin reaction severity was measured using the modified Radiation-Induced Skin Reaction Assessment Scale (RISRAS) and Radiation Therapy Oncology Group grades. Stress levels were determined using a 5-point LIKERT scale to rate physical well-being, managing stress levels, house, family, work and other commitments. A total of 20 patients (26%) of the 78-patient cohort were considered stressed. Skin reaction severity in stressed patients was twice that of non-stressed patients (p < 0.001) and stressed patients were five times more likely to develop moist desquamation. Our results show that psychological stress aggravates skin reaction severity during radiation therapy. This research needs to be validated in a more rigorous manner by incorporating a validated scale such as the Distress Thermometer and Impact Thermometer in future skin trials.

RESUMO

The aim of this systematic review is to assess the available evidence concerning the effectiveness of semi-permeable dressings, on the full range of skin reactions, related to radiation therapy in cancer patients, from local erythema to moist desquamation, including subjective symptoms such as pain, discomfort, itchiness, burning and the effect on daily life activities. The bibliographic search was carried out looking for Randomised Clinical Trials (RCTs) indexed in PubMed, Cinhal, Cochrane plus and Biblioteca Nacional de Salud, published in the English and Spanish language, between 2010 and 2015. Data extraction and evaluation of study quality was undertaken by peer reviewers using the Critical Appraisal Skills Programme (CASP). Of 181 studies, nine full texts were assessed. Finally, six RCT were included in the final synthesis: three analysed the application of Mepilex® Lite in breast cancer and head & neck cancer; one evaluated the application of Mepitel® Film in breast cancer; and two assessed the use of silver nylon dressings in breast cancer and in patients with lower gastrointestinal cancer. The results show that semi-permeable dressings are beneficial in the management of skin toxicity related to radiation therapy. However, rigorous trials showing stronger evidence are needed.

RESUMO

Breast cancer is the most common cancer in women worldwide, with an incidence of 1.7 million in 2012. Breast cancer and its treatments can bring along serious side effects such as fatigue, skin toxicity, lymphedema, pain, nausea, etc. These can substantially affect the patients' quality of life. Therefore, supportive care for breast cancer patients is an essential mainstay in the treatment. Low-level light therapy (LLLT) also named photobiomodulation therapy (PBMT) has proven its efficiency in general medicine for already more than 40 years. It is a noninvasive treatment option used to stimulate wound healing and reduce inflammation, edema, and pain. LLLT is used in different medical settings ranging from dermatology, physiotherapy, and neurology to dentistry. Since the last twenty years, LLLT is becoming a new treatment modality in supportive care for breast cancer. For this review, all existing literature concerning the use of LLLT for breast cancer was used to provide evidence in the following domains: oral mucositis (OM), radiodermatitis (RD), lymphedema, chemotherapy-induced peripheral neuropathy (CIPN), and osteonecrosis of the jaw (ONJ). The findings of this review suggest that LLLT is a promising option for the management of breast cancer treatment-related side effects. However, it still remains important to define appropriate treatment and irradiation parameters for each condition in order to ensure the effectiveness of LLLT.

RESUMO

BACKGROUND: Radiation recall dermatitis (RRD) is an acute inflammatory reaction confined to previously irradiated skin, mainly subsequent to the administration of certain chemotherapeutics. Here we present a rare case of RRD induced by the oral multikinase inhibitor sorafenib. CASE REPORT: A 77-year-old male with hepatocellular carcinoma was irradiated at ten different sites for bone metastases with 20-36 Gray in 5-12 fractions from January to March 2015. Sorafenib 400 mg was administered twice daily from mid-March. One week later the patient presented with fever and erythematous lesions on the right upper arm, mandible, and trunk. All skin symptoms were confined to previously irradiated areas. After RRD was diagnosed by exclusion of other causes and skin biopsy, sorafenib was paused. With the administration of topical corticosteroids and oral antihistamines, the skin reaction subsided within several days. Sorafenib was readministered after 3 weeks, which did not lead to recurrence of RRD but did cause fluctuating fever. DISCUSSION: Only four other such cases have been reported in the literature and WHO pharmacovigilance database on individual case safety reports. The current report is the first to show a potential relationship between the severity of sorafenib-induced RRD and radiation dose, histopathological features, and simultaneous acute radiation dermatitis and mucositis. CONCLUSION: RRD induced by sorafenib is a rare phenomenon, but should be considered in patients showing erythematous skin lesions 1-2 weeks after initiation of the drug, predominantly in areas where skin has been irradiated with an equivalent dose ≥ 30 Gy. Discontinuation of sorafenib with possible readministration should be evaluated with respect to the clinical situation and severity of reaction.

RESUMO

This article describes the prophylactic use of Mepitel Film in three breast-cancer patients undergoing adjuvant radiotherapy. Each patient had significant risk factors for developing severe radiotherapy-induced skin reactions. This article details the experience encountered by these patients through their treatment courses, with observations by the review radiographers responsible for the care and support of these patients during their radiotherapy and the patients themselves. The film was found to be easy to use by the clinical team and resulted in a significant reduction in adverse side effects to the skin, with an associated improvement in patient satisfaction. There was found to be a financial benefit with the use of Mepitel Film when compared to the foam dressings often required for wound management if the patients had suffered moist desquamation.

RESUMO

BACKGROUND AND PURPOSE: Head and neck cancer patients frequently develop radiation dermatitis (RD) during radiotherapy. We compared liposomal gel with and without chamomile extract for the prevention and management of RD in head and neck cancer patients undergoing radiotherapy. MATERIALS AND METHODS: Sixty participants undergoing radiotherapy for the first time for head and neck cancer were recruited in a double-blind randomized clinical trial. Primary outcomes were the occurrence of dry desquamation and the cumulative dose of ionizing radiation at the first occurrence of dry desquamation. Secondary outcomes were the occurrence of erythema, moist desquamation, global RD, and participant self-reported symptoms. RESULTS: Dry desquamation occurred in 76.9 % (95 % CI: 57.9, 89.0) of participants in the chamomile liposomal gel group and in 88.9 % (95 % CI: 71.9, 96.1) in the liposomal gel group (p = 0.43). The median cumulative dose of ionizing radiation when dry desquamation occurred was 48.0 Gy in the chamomile liposomal gel group and 40.0 Gy in the liposomal gel group. Fewer symptoms were reported in the chamomile liposomal gel group. CONCLUSION: No statistically significant differences in outcomes were found between the two groups, though the chamomile liposomal gel group presented with lower grades of RD than the liposomal gel group. In addition, when compared to the literature on other topical interventions to manage RD, our results show that chamomile liposomal gel has potential for better management and prevention of RD in this population, which should be further tested. This study provides crucial information to design future studies. Clinical Trials Registration (REBEC): RBR-92cts3.

RESUMO

Episil is a bioadhesive barrier-forming liquid gel that can relieve mucositis caused by radiotherapy (RT) and effectively relieve pain. The purpose of this trial is to compare the efficacy and safety of Episil in improving acute radiation dermatitis (ARD) in patients with breast cancer. This study included patients who met the criteria for postoperative RT for breast cancer. The primary end point was the grade of RD during treatment. A total of 102 patients were included in this study. The patients were grouped in a 2:1 ratio using the randomized number table method: 67 patients received Episil combined with conventional skin care (the Episil group), whereas the remaining 35 patients served as the control group and received conventional skin care only (the control group). According to the grading criteria of the Radiation Therapy Oncology Group (RTOG), the skin reaction rate and severity were significantly better in the Episil group than the control group (24.62%, 72.31%, 3.08, 0, 0 vs. 0, 85.71%, 14.29%, 0, 0, 0) across grades 0 to 4 (P < 0.05). The itchiness score exhibited s significant reduction in the Episil group as compared with the control group (P < 0.05). The results of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) showed that the overall health (z = -5.855, P < 0.001) and overall quality of life (z = -6.583, P < 0.001) were better in the Episil group than the control group after RT. Overall, in patients with breast cancer receiving RT, the topical application of Episil may significantly reduce the grading of ARD, alleviate patient symptoms, and improve the patient's overall quality of life.

RESUMO

Radiotherapy is a pivotal means of cancer treatment, but it often leads to radiation dermatitis, a skin injury caused by radiation-induced excess reactive oxygen species (ROS). Scavenging free radicals in the course of radiation therapy will be an effective means to prevent radiation dermatitis. This study demonstrates a novel double network hydrogel doped with MoS2 nanosheets for the prevention of radiation-induced dermatitis. The resultant SPM hydrogel constructed from polyacrylamide (PAM) and sodium alginate (SA) nanofiber presented favorable mechanical and adhesion properties. It could conform well to the human body's irregular contours without secondary dressing fixation, making it suitable for skin protection applications. The in vitro and in vivo experiments showed that the antioxidant properties conferred by MoS2 nanosheets enable SPM to effectively mitigate excessive ROS and reduce oxidative stress, thereby preventing radiation dermatitis caused by oxidative damage. Biosafety assessments indicated good biocompatibility of the composite hydrogel, suggesting SPM's practicality and potential as an external dressing for skin radiation protection.

RESUMO

PEGylated superoxide dismutase (PEG-SOD) is commonly used as a cytoprotective agent in radiotherapy. However, its effectiveness in preventing radiation dermatitis is limited owing to its poor skin permeability. To address this issue, a PEG-SOD-loaded dissolving microneedle (PSMN) patch was developed to effectively prevent radiation dermatitis. Initially, PSMN patches were fabricated using a template mold method with polyvinylpyrrolidone K90 as the matrix material. PSMNs exhibited a conical shape with adequate mechanical strength to penetrate the stratum corneum. More than 90 % of PEG-SOD was released from the PSMN patches within 30 min. Notably, the PSMN patches showed a significantly higher drug skin permeation than the PEG-SOD solutions, with a 500-fold increase. In silico simulations and experiments on skin pharmacokinetics confirmed that PSMN patches enhanced drug permeation and skin absorption, in contrast to PEG-SOD solutions. More importantly, PSMN patches efficiently mitigated ionizing radiation-induced skin damage, accelerated the healing process of radiation-affected skin tissues, and exhibited highly effective radioprotective activity for DNA in the skin tissue. Therefore, PSMN patches are promising topical remedy for the prevention of radiation dermatitis.

RESUMO

PURPOSE: Radiation dermatitis (RD) is common in patients undergoing breast radiotherapy. Mepitel film (MF) can reduce RD, but the results from two randomized controlled trials are conflicting. We aimed to conduct a confirmatory randomized controlled trial in patients at risk of RD. METHODS: Patients were randomly assigned to receive MF or standard care (2:1 ratio). Patients with large breasts after lumpectomy (bra size ≥ 36 inches or cup size ≥ C) or after mastectomy were eligible. Stratification factors included surgery type, dose fractionation, and administration of boost/bolus. The primary end point was grade (G) 2 or 3 RD using the Common Terminology Criteria for Adverse Events v5.0. Secondary end points included patient- and clinician-reported outcomes. RESULTS: Between January 2020 and May 2022, 376 patients were included in the modified intention-to-treat analysis. The incidence of G2 or 3 RD was significantly lower in MF patients compared with standard care (n = 39/251, 15.5%; 95% CI, 11.3 to 20.6% v n = 57/125, 45.6%; 95% CI, 36.7 to 54.8% respectively, odds ratio (OR): 0.20, P < .0001). Benefits of MF remained significant in patients who developed G 3 RD (n = 7, 2.8%; 95% CI, 1.1 to 5.7% v n = 17, 13.6%; 95% CI, 8.1 to 20.9%, OR: 0.19) and moist desquamation (n = 20, 8.0%; 95% CI, 4.9 to 12.0% v n = 24, 19.2%; 95% CI, 12.7 to 27.1%, OR: 0.36). When evaluating the combined patient and health care provider score using Radiation-Induced Skin Reaction Assessment Scale, the MF arm had significantly lower scores (P < .0001). Individual items on the Radiation-Induced Skin Reaction Assessment Scale also favored the MF for both patient- and clinician-reported outcomes. Blistering/peeling, erythema, pigmentation, and edema were significantly reduced in the MF arm. Three patients removed the film prematurely because of rash (n = 2) and excessive pruritus (n = 1). CONCLUSION: MF significantly reduces RD in patients undergoing breast radiotherapy.

RESUMO

BACKGROUND/AIM: Several reports have evaluated the efficacy and safety of concurrent radiotherapy with cetuximab (BRT) in patients with nasopharyngeal carcinoma (NPC). Combination therapy with cetuximab can be a treatment option for NPC. Although clinical data regarding the efficacy and safety of BRT without induction chemotherapy (ICT) or adjuvant chemotherapy is essential for the development of new therapeutic strategies, such data are rarely reported. PATIENTS AND METHODS: We retrospectively investigated a series of patients with NPC treated in our institution to evaluate the efficacy and safety of BRT. Eleven patients with newly diagnosed NPC were identified from an inpatient database from July 2015 to April 2018. Seven patients who received BRT were reviewed. RESULTS: All patients completed BRT without cessation of treatment. Six (85.7%) patients achieved a complete response and one (14.3%) achieved stable disease. The response rate was 85.7%. All patients with ≤T3 disease achieved a complete response. Both patients with T3 disease developed local recurrence, and one of the four patients with T1-2 disease developed distant metastases. The 1- and 3-year overall survival rates were 85.7% and 47.6%, respectively. The most common adverse events (AEs) were pharyngeal mucositis (100%), radiation dermatitis (100%), anorexia (28.6%), weight loss (28.6%), acneiform rash (28.6%), and dry mouth (28.6%). Grade 3 AEs were pharyngeal mucositis (42.9%), radiation dermatitis (28.6%), and anorexia (14.3%). No grade 4/5 AEs were observed. CONCLUSION: BRT for NPC was tolerable, but our findings suggest that BRT without induction chemotherapy or adjuvant chemotherapy is insufficient at least for ≥T3 disease.

RESUMO

PURPOSE: Severe radiation dermatitis (RD) is distressing and may have adverse long-term effects including fibrosis and telangiectasia. Treatment interruptions due to severe RD may increase the risk of recurrence. Two randomized trials of Mepitel film demonstrated efficacy in preventing severe RD in breast cancer, but this product has not been widely adopted in North America. We aimed to assess the feasibility and efficacy of Mepitel film for prevention of breast RD at a Canadian center. METHODS AND MATERIALS: Patients were stratified based on breast size and receipt of postmastectomy radiation therapy. The primary outcome was RD grade using the Common Terminology Criteria for Adverse Events. Secondary outcomes included moist desquamation, patient- and clinician-reported symptoms of skin toxicity, and cosmetic outcomes. RESULTS: Thirty patients receiving external beam radiation therapy to the breast or chest wall were enrolled. Two patients (6.7%) discontinued use of the Mepitel film before completing radiation therapy. No patients developed grade 3 RD or higher. Five patients (17.9%) developed grade 2 RD: 3 (10.7%) had moist desquamation, and 2 (7.1%) had brisk erythema without moist desquamation. CONCLUSIONS: Mepitel film completely prevented grade 3 RD. Rates of moist desquamation and grade 2 RD were lower with Mepitel film than in studies using aqueous cream, but unlike previous trials of Mepitel film we did not achieve complete prevention of moist desquamation. Further research is needed to confirm the efficacy of Mepitel film versus standard prophylaxis for RD and identify the patients who will benefit the most from the film.

RESUMO

Purpose of this review of medical literature is to present the immediate side effects of radiation therapy for head and neck cancer and their treatment. The likelihood and severity of these immediate side effects depends on a number of factors, including the total dose of radiation delivered, over what time it was delivered and what parts of the head and neck received radiation. Early side effects include: inflammation of the oropharyngeal mucosa (mucositis), painful swallowing (odynophagia), difficulty swallowing (dysphagia), hoarseness, lack of saliva (xerostomia), orofacial pain, laryngeal radionecrosis, dermatitis, hair loss, nausea, vomiting, inadequate nutrition and hydration, and weight loss. These complications can interfere with, and delay treatment. Most of these side effects generally dissipate over time. In conclusion, radiation treatment for the head and neck cancer causes significant early side effects. Many of these side effects present difficult challenges to the patients. Their recognition and treatment can significantly improve the patients' health, long-term survival and quality of life. The review provides information that can assist head and cancer survivors deal with radiation side effects.

RESUMO

BACKGROUND/AIM: To evaluate whether topical use of a film-forming silicone gel (StrataXRT®) could reduce radiation dermatitis compared to a moisturizing cream (X-derm®) in patients receiving whole breast radiotherapy. PATIENTS AND METHODS: A total of 56 patients with breast cancer were randomized to use StrataXRT or X-derm. The severity of radiation dermatitis was graded using physiological skin parameters, clinician-assessed visual rating scales and patient-reported symptoms. Changes in these parameters from baseline to 4 weeks post-radiotherapy were evaluated every two weeks. RESULTS: Two-way repeated-measures ANOVA revealed different patterns of changes in the erythema index (F=3.609, p=0.008) and melanin index (F=3.475, p=0.015). The post hoc analysis demonstrated a significantly lower erythema index and melanin index in the patients allocated to the StrataXRT group. CONCLUSION: The use of StrataXRT can reduce radiation dermatitis with respect to objectively measured physiological skin parameters. The results of the present study will support the feasibility of conducting a larger randomized controlled trial.

RESUMO

Radiation recall dermatitis (RRD) is a rare cutaneous reaction occurring within a previously irradiated field, precipitated by certain drugs. We report a case of RRD occurring after pre-sensitization with pegylated liposomal doxorubicin (PLD) in a woman with Stage IV breast cancer. The RRD occurred in one of the patient's four previous radiotherapy fields. We discuss the time/dose factors of radiation exposure and measure the corresponding skin dose. In our case the radiation dose was low and below previously reported thresholds, and illustrates that there is a more complex interaction between the radiotherapy and the trigger agent than has previously been considered.
