Comparison of liposomal gel with and without addition of chamomile for prevention of radiation dermatitis in head and neck cancer patients: A randomized controlled trial

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.

Evidence-based summary of the prevention and management of radiation dermatitis in patients with breast cancer

Objective

Up to now there is a lack of research to summarize the relevant evidence for radiation dermatitis (RD) management in patients with breast cancer. Therefore, this study aimed to summarize the best evidence for the prevention and management of RD in patients with breast cancer.

Methods

According to the "6S" evidence pyramid model, all major databases were searched from January 2018 to February 2024: UpToDate, BMJ Best Practice, National Guideline Clearinghouse, Guidelines International Network, MedSci, Yi Maitong Guidelines, National Comprehensive Cancer Network, Oncology Nursing Society, Radiology Assistant database, Society and College of Radiographers, Australian JBI Evidence-Based Health Care Center database, Cochrane Library, PubMed, CINAHL, Embase, Web of Science, China National Knowledge Infrastructure, Wangfang Data, Chinese Science and Technology Journal Database, Chinese Biology Medicine, etc.

Results

A total of 22 articles which met the inclusion criteria were included in the study, comprising six guidelines, nine systematic reviews, four evidence summaries, one clinical decision, one expert consensus, and one randomized controlled trial. We summarized 35 pieces of evidence across four aspects: influence factor, evaluation and monitoring, prevention and treatment, care and health education.

Conclusions

This study provides a comprehensive summary of the best evidence for the prevention and management of RD in patients with breast cancer. It is recommended that subsequent evidence transformation should be conducted based on specific clinical circumstances to standardize the process of clinical prevention and management of RD.

Anti-Cancer Properties of Two Intravenously Administrable Curcumin Formulations as Evaluated in the 3D Patient-Derived Cancer Spheroid Model

Curcumin (Cur) is a heavily used complementary derived drug from cancer patients. Spheroid samples derived from 82 patients were prepared and treated after 48 h with two Cur formulations (CurA, CurB) in mono- and combination therapy. After 72 h, cell viability and morphology were assessed. The Cur formulations had significant inhibitory effects of -8.47% (p < 0.001), CurA of -10.01% (-50.14-23.11%, p = 0.001) and CurB of -6.30% (-33.50-19.30%, p = 0.006), compared to their solvent controls Polyethylene-glycol, β-Cyclodextrin (CurA) and Kolliphor-ELP, Citrate (CurB). Cur formulations were more effective in prostate cancer (-19.54%) and less effective in gynecological non-breast cancers (0.30%). CurA showed better responses in samples of patients <40 (-13.81%) and >70 years of age (-17.74%). CurB had stronger effects in metastasized and heavily pretreated tumors. Combinations of Cur formulations and standard therapies were superior in 20/47 samples (42.55%) and inferior in 7/47 (14.89%). CurB stimulated chemo-doublets more strongly than monotherapies (-0.53% vs. -6.51%, p = 0.022) and more effectively than CurA (-6.51% vs. 3.33%, p = 0.005). Combinations of Cur formulations with Artesunate, Resveratrol and vitamin C were superior in 35/70 (50.00%) and inferior in 16/70 (22.86%) of samples. Cur formulations were significantly enhanced by combination with Artesunate (p = 0.020). Cur formulations showed a high variance in their anti-cancer effects, suggesting a need for individual testing before administration.

Radiation-induced skin injury in the head and neck region: pathogenesis, clinics, prevention, treatment considerations and proposal for management algorithm

Worldwide increase of head and neck cancers ranks these malignancies among top causes of cancer in human population. Radiation induced skin injury (RISI) is one of the major side effects of radiotherapy (RT). Skin of the neck is exposed to radiation due to necessity of therapeutic or prophylactic (elective) irradiation of neck lymph nodes and target organs, including the larynx and hypopharynx. The location of the neck exposes these regions of the skin to various additional exposomes such as ultraviolet radiation (UVR), pollution and cigarette smoke. There are many controversies or inconsistencies regarding RISI, from molecular aspects and therapy to terminology. There is lack of high-quality and large-sample studies in both forms of RISI: acute (aRISI) and chronic (cRISI). Finally, no gold standards in the management of aRISI and cRISI have been established yet. In this article, the authors discuss the pathogenesis, clinical picture, prevention and clinical interventions and present a proposed treatment algorithm.

A topical BRAF inhibitor (LUT-014) for treatment of radiodermatitis among women with breast cancer

Background

Modern radiotherapy is associated with dermatitis (RD) in approximately one-third of patients treated for breast cancer. There is currently no standard for treating RD.

Objective

The objective of this study was to determine whether LUT014, a topical BRAF inhibitor which paradoxically activates mitogen-activated protein kinase, can safely improve RD.

Methods

A phase I/II study was designed to first follow a small cohort of women with grade 2 RD regarding toxicity and response. Then, 20 patients were randomized to compare LUT014 to "vehicle" relative to safety and response (measured with common terminology criteria for adverse events, Dermatology Life Quality Index).

Results

No substantial toxicity (eg, 0 serious adverse event) was associated with LUT014. All 8 women receiving LUT014 achieved treatment success (5-point Dermatology Life Quality Index reduction at day 14) compared to 73% (8/11) on the placebo arm (P = .591). The time to complete recovery was shorter in the treatment arm.

Limitations

The sample size was limited. Only 2 hospitals were included.

Conclusions

Topical LU014 is tolerable and may be efficacious for grade 2 RD.

Effectiveness of glutamine for the treatment of radiodermatitis in cancer patients: a meta-analysis of randomized controlled trials

BACKGROUND

After receiving radiation therapy, 60%-95% of patients with cancer develop radiodermatitis, which causes pain, wound infection, and poor quality of life. Glutamine is a popular nutritional supplement for patients with cancer. Several studies examined the usefulness of glutamine for reducing radiodermatitis. However, there is still no consolidated evidence for clinical use.

METHODS

We searched PubMed, Embase, Cochrane Library, CINAHL PLUS, and the China Knowledge Resource Integrated Database for the relevant literature published up to March 2023, without language restrictions. Two reviewers screened, filtered, and appraised these articles independently, and their data were pooled using a random-effects model.

RESULTS

Five randomized controlled trials (RCTs) with 218 participants were analyzed. The incidence of radiodermatitis in the glutamine group (89/110) was significantly lower than in the placebo group (99/108; risk ratio [RR], 0.90; 95% CI, 0.81-1.00; p = 0.05; I2 = 7%). The incidence of moderate to severe radiodermatitis was significantly lower in the glutamine group than in the placebo group (RR, 0.49; 95% CI, 0.32-0.76; p = 0.001; I2 = 52%). Moreover, subgroup analysis demonstrated heterogeneity (I2 = 52%) for moderate to severe radiodermatitis, the risk of which might be significantly reduced by a glutamine dose of 20-30 g/day (RR, 0.60; 95% CI, 0.41-0.87; I2 = 0%).

CONCLUSION

The meta-analysis indicate that glutamine might lead to a lower incidence of radiodermatitis, and that a glutamine dose of 20-30 g/day might decrease the incidence of moderate to severe dermatitis. Thus, the serious impact of radiodermatitis on treatment follow-up makes the clinical use of glutamine even more important. PROSPERO number: CRD42021254394.

StrataXRT for the prevention and treatment of radiation dermatitis: a critical review

PURPOSE

The primary objective is to systematically review primary studies, such as randomized control trials (RCTs), feasibility, exploratory, and case studies; and the secondary objective is to evaluate all secondary articles, such as reviews, guidelines, and editorials, relevant to the use of StrataXRT for the prevention and/or management of radiation dermatitis (RD) in cancer patients.

METHODS

A literature search was conducted up to February 26, 2023, for articles investigating the use of StrataXRT for the prevention and treatment of RD, in the following databases: Ovid MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar. The keywords "StrataXRT", "dermatitis", "radiotherapy", and "radiation" were used to identify relevant articles.

RESULTS

Twenty-seven articles from 2018 to 2022 were identified to fulfill the inclusion criteria of this review, of which nine are primary studies and 18 are secondary papers. Significant heterogeneity was observed in the current literature studying the effects of StrataXRT, making it difficult to make cross-trial comparisons. There is a suggestion of the efficacy of StrataXRT in the prevention and treatment of RD.

CONCLUSION

The findings of this review recommend further adequately powered RCTs with robust methodology including patient and clinician assessments to determine the efficacy of StrataXRT in preventing and treating RD. This is essential to improve the quality of life of patients and identify which groups of patients would benefit most from StrataXRT.

A novel, multi-active emollient for the prevention of acute radiation dermatitis in breast cancer patients: a randomized clinical trial

PURPOSE

To investigate the efficacy of a novel, multi-active emollient in preventing and managing acute radiation dermatitis (ARD) in breast cancer patients undergoing moderate hypofractionated (HF) radiotherapy (RT) compared to standard of care.

METHODSA

A monocentric, open-label, randomized clinical trial (RCT) with breast cancer patients receiving moderate HF (dose: 40.05-55.86 Gy, fractions: 15-21) was conducted between January 2022 and May 2023. The experimental group received the novel emollient, while the control group received the standard skin care. Patients applied the skin care products twice daily during the complete RT course. The primary outcome was the severity of ARD at the final RT session measured by the modified Radiation Therapy Oncology Group (RTOG) criteria. Secondary outcomes included patient symptoms, quality of life (QoL), and treatment satisfaction.

RESULTS

A total of 100 patients with 50 patients per group were enrolled. In the control group, 50% of the patients developed RTOG grade 1 ARD and 48% grade 2 or higher, while in the experimental group, the severity of ARD was significantly lower with 82% grade 1 and 16% grade 2 ARD (P = .013, χ2-test). The frequency and severity of xerosis were significantly lower in the experimental compared to the control group (Ps ≤ .036, Mann Whiney U test). The impact of ARD on the QoL was low, and treatment satisfaction was high in both groups, with no significant difference.

CONCLUSION

This RCT shows that the novel, multi-active emollient significantly reduced the ARD RTOG grade. Research in a more diverse patient population is warranted.

Prevention of radiation dermatitis with skin hygiene and washing: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aims to evaluate the effects of washing in patients receiving radiotherapy (RT) on radiation dermatitis (RD) severity.

METHODS

A literature search was performed using Ovid MEDLINE, Embase, and Cochrane databases between January 1, 1946, and January 31, 2023. Four randomized controlled trials (RCTs) studying the effects of washing with or without soap on RD were identified. A meta-analysis was conducted for clinician-reported outcomes using RevMan 5.4 and a narrative synthesis for patient-reported outcomes due to a lack of reported data amenable to quantitative comparison in accordance with the Synthesis Without Meta-analysis (SWiM) guidelines. The Cochrane Risk of bias (RoB2) and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria were used to assess risk of bias and certainty of evidence, respectively.

RESULTS

Two RCTs met the inclusion criteria for meta-analysis. Washing with or without soap significantly reduced the incidence of severe RD (OR: 0.32, 95% CI: 0.19-0.55, p < 0.01) and moist desquamation (OR: 0.25, 95% CI: 0.12-0.52, p < 0.01). Two of four trials found an association between washing and reduced itching score (p = 0.38). Pain score was not found to be significantly different with or without washing in any of the four studies (p = 0.07). The two studies that assessed burn scores did not detect any difference between the washing group versus no washing group (p = 0.25). Washing was associated with improved quality of life (QoL) measures in one study.

CONCLUSION

Washing with or without soap during RT resulted in less severe RD and less moist desquamation. Given the QoL benefits of washing, it should be advocated as part of routine skin care during RT.

Systematic review and meta-analysis on interventions for radiation dermatitis prevention and management: an overview of the methods

Over several decades, research on the prevention and management of acute radiation dermatitis (RD) has continued to emerge, yet there remains no "gold standard" treatment for RD care. Recent guidelines on RD prevention and management were published in 2022 by the Oncodermatology Study Group of the Multinational Association of Supportive Care in Cancer (MASCC). As part of this guideline process, a collaborative effort was undertaken by international RD experts to quantitatively compare commonly studied RD skin interventions through meta-analyses and discern superiority of interventional treatments over another intervention, standard-of-care, or placebo in RD prevention and management. This paper summarizes the materials and methodology used in a set of meta-analysis studies that supplement the 2022 MASCC Clinical Practice Guidelines on RD Prevention and Management.

Multinational Association of Supportive Care in Cancer (MASCC) clinical practice guidelines for the prevention and management of acute radiation dermatitis: international Delphi consensus-based recommendations

Acute radiation dermatitis is a frequent adverse effect of radiotherapy, but standardisation of care for acute radiation dermatitis is lacking. Due to the conflicting evidence and variability in current guidelines, a four-round Delphi consensus process was used to compile opinions of 42 international experts on care for people with acute radiation dermatitis on the basis of the evidence in existing medical literature. Interventions for acute radiation dermatitis prevention or management that reached at least 75% consensus were recommended for clinical use. Six interventions could be recommended for the prevention of acute radiation dermatitis: photobiomodulation therapy and Mepitel film in people with breast cancer, Hydrofilm, mometasone, betamethasone, and olive oil. Mepilex Lite dressings were recommended for the management of acute radiation dermatitis. Most interventions were not recommended due to insufficient evidence, conflicting evidence, or lack of consensus to support use, suggesting a need for further research. Clinicians can consider implementing recommended interventions in their practice to prevent and manage acute radiation dermatitis until additional evidence becomes available.

Barrier Films and Dressings for the Prevention of Acute Radiation Dermatitis: A Systematic Review and Meta-Analysis

PURPOSE

This systematic review and meta-analysis aimed to evaluate the efficacy of barrier films and dressings in preventing acute radiation dermatitis (RD).

METHODS

OVID Medline, Embase, and Cochrane databases were searched from 1946 to September 2020 to identify randomized controlled trials on the use of barrier films or dressings to prevent RD. For comparable outcomes between studies, pooled effect sizes and 95% confidence intervals (CI) were calculated using the random effects analysis in RevMan 5.4.

RESULTS

Fourteen and 11 studies were included in the qualitative and quantitative analyses, respectively. Five types of barrier films used for RD were identified: Hydrofilm, StrataXRT®, Mepitel® Film, 3 M™ Cavilon™ No-Sting Barrier Film, and silver leaf nylon dressing. Hydrofilm and Mepitel Film significantly reduced the development of RD grade ≥ 2 in breast and head and neck cancer patients (RR 0.32, 95%CI 0.19, 0.56, p < 0.0001; RR 0.21, 95%CI 0.05, 0.89, p = 0.03, resp.). Moreover, Hydrofilm had a beneficial effect on patient-reported outcomes (PROs) (SMD -0.75, 95%CI -1.2, -0.29, p = 0.001). The meta-analyses on the other barrier films did not show any significant effect.

CONCLUSION

This review and meta-analysis demonstrated that Hydrofilm and Mepitel Film could effectively reduce RD severity and improve PROs. The evidence is generally weak for all the studies on barrier films and dressings due to a limited study number, high risk of bias, small sample sizes, and minimal comparable outcome measures. It's potential has been proven, but future research in this field is recommended to confirm the efficacy of these products and assess real-world feasibility.

Topical non-steroidal agents for the prevention of radiation dermatitis: a systematic review and meta-analysis

PURPOSE

Radiation dermatitis (RD) is a common side effect of radiation therapy, affecting a majority of breast and head and neck cancer patients with a negative impact on quality of life. Currently, no consensus exists regarding the prevention of RD.

METHODS

PubMed, Embase and Cochrane databases (1946 to December 2022) were searched using PRISMA guidelines to identify randomized controlled trials (RCTs) that investigated the use of topical non-steroidal agents in the prevention of RD in patients undergoing radiotherapy.

RESULTS

A total of six RCTs were included, comprising 627 patients. Among the topical non-steroidal agents analyzed, only the use of Biafine® in breast cancer patients was significant in preventing grade 4 and 3 + RD as classified by the Radiation Therapy Oncology group (RTOG) scale (OR = 0.07, 95% CI 0.01-0.63, p = 0.02, and OR 0.11, 95% CI 0.03-0.41, p < 0.01, respectively). The remaining agents (trolamine alone and hyaluronic acid/hyaluronan) did not significantly prevent the occurrence of RD.

CONCLUSION

The results of this systematic review and meta-analysis indicate that Biafine® can prevent grade 3 + RD in breast cancer patients. The use of trolamine and hyaluronic acid does not significantly affect the incidence of RD.

The effect of antiperspirant and deodorant use on acute radiation dermatitis in breast cancer patients during radiotherapy: a systematic review and meta-analysis

PURPOSE

While some authors have investigated the impact of antiperspirant /deodorant on the development of acute radiation dermatitis (RD) among patients undergoing radiotherapy (RT) for breast cancer, recommendations supporting the use of antiperspirant/deodorant during breast RT remain highly variable. This systematic review and meta-analysis aims to evaluate the evidence investigating the effect of antiperspirant/deodorant on the development of acute RD during post-operative breast RT.

METHODS

A literature search has been performed using OVID MedLine, Embase, and Cochrane databases (1946 to September 2020) to identify randomized controlled trials (RCTs) that have investigated deodorant/antiperspirant use during RT. The meta-analysis was conducted using RevMan 5.4 to calculate pooled effect sizes and 95% confidence intervals (CI).

RESULTS

Five RCTs met the inclusion criteria. The use of antiperspirant/deodorant did not significantly affect the incidence of grade (G) 1 + RD (OR 0.81, 95% CI 0.54-1.21, p = 0.31). Prohibition of deodorant use did not significantly prevent the occurrence of G2 + acute RD (OR 0.90, 95%, CI 0.65-1.25, p = 0.53). No significant effect was reported in preventing G3 RD between the antiperspirant/deodorant and control groups (OR 0.54, 95%, CI 0.26-1.12, p = 0.10). There was no significant difference in pruritus and pain between patients undergoing skin care protocols with or without antiperspirant/deodorant (OR 0.73, 95% CI 0.29, 1.81, p = 0.50, and OR 1.05, 95% CI 0.43-2.52, p = 0.92, respectively).

CONCLUSIONS

The use of antiperspirant/deodorant during breast RT does not significantly affect the incidence of acute RD, pruritus, and pain. As such, the current evidence does not support recommendation against antiperspirant/deodorant use during RT.

Natural and miscellaneous agents for the prevention of acute radiation dermatitis: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to evaluate the available literature describing the efficacy of natural and miscellaneous agents in preventing acute radiation dermatitis (RD) in cancer patients.

METHODS

OVID MedLine, Embase, and Cochrane literature databases were searched from 1946 to January 2023 for randomized controlled trials studying the use of natural and miscellaneous agents to prevent RD. RevMan 5.4 was used for the meta-analysis to calculate the pooled effect sizes and 95% confidence intervals (CI) using the random effects analysis.

RESULTS

For the systematic review and meta-analysis, 19 and 16 studies were included, respectively. Of the five studied natural products (aloe vera, oral enzymes, olive oil, calendula, and curcumin), only oral enzymes and olive oil significantly reduced the incidence of Radiation Therapy Oncology Group grade 2⁺ (RR: 0.42, 95%CI 0.30-0.58, p < 0.00001, RR: 0.66, 95% CI 0.51-0.85, p = 0.001, resp.). The oral enzymes also reduced the grade 3⁺ RD incidence (RR: 0.18, 95%CI 0.06-0.55, p = 0.003). The other agents demonstrated no significant effect.

CONCLUSION

This review and meta-analysis on natural and miscellaneous agents in preventing RD in cancer patients demonstrated that oral enzymes and olive oil prevented RD severity. However, evidence supporting natural agents to prevent RD is inconsistent, mainly because of low studies numbers, low-quality study designs, and small sample sizes. Therefore, concrete conclusions cannot be made. Research on (new) natural or miscellaneous agents should focus on a randomized controlled double-blinded study design with a large patient population, a higher consistency in research methods, and clinician- and patient-reported outcomes.

Smoking and Radiation-induced Skin Injury: Analysis of a Multiracial, Multiethnic Prospective Clinical Trial

INTRODUCTION

Smoking during breast radiotherapy (RT) may be associated with radiation-induced skin injury (RISI). We aimed to determine if a urinary biomarker of tobacco smoke exposure is associated with increased rates of RISI during and after breast RT.

PATIENTS AND METHODS

Women with Stage 0-IIIA breast cancer treated with breast-conserving surgery or mastectomy followed by RT to the breast or chest wall with or without regional nodal irradiation were prospectively enrolled on a multicenter study assessing acute/late RISI. 980 patients with urinary cotinine (UCot) measurements (baseline and end-RT) were categorized into three groups. Acute and late RISI was assessed using the ONS Acute Skin Reaction scale and the LENT-SOMA Criteria.

RESULTS

Late Grade 2+ and Grade 3+ RISI occurred in 18.2% and 1.9% of patients, respectively-primarily fibrosis, pain, edema, and hyperpigmentation. Grade 2+ late RISI was associated with UCot group (P= 006). Multivariable analysis identified UCot-based light smoker/secondhand smoke exposure (HR 1.79, P= .10) and smoking (HR 1.60, p = .06) as non-significantly associated with an increased risk of late RISI. Hypofractionated breast RT was associated with decreased risk of late RISI (HR 0.51, P=.03). UCot was not associated with acute RISI, multivariable analysis identified race, obesity, RT site/fractionation, and bra size to be associated with acute RISI.

CONCLUSIONS

Tobacco exposure during breast RT may be associated with an increased risk of late RISI without an effect on acute toxicity. Smoking cessation should be encouraged prior to radiotherapy to minimize these and other ill effects of smoking.

Effect of standard skin care treatments on skin barrier function in X-irradiated hairless mice

Objective

The effectiveness of skin care to radiation dermatitis (RD) on patients who received radiotherapy for cancer has not been clarified. The purpose of this study was to investigate the effect of moisturizers and skin washing on skin barrier function possibly leading to the development of RD using X-ray irradiated hairless mice.

Methods

Nine-week-old hairless mice were irradiated with 10 ​Gy of X-rays, and the skin care group had moisturizers applied or skin washing with soap from the day of irradiation during observations. The condition of the skin was observed to evaluate RD. Skin barrier function was evaluated by measuring skin temperature and transepidermal water loss (TEWL) once every two days until 25 days after X-ray irradiation.

Results

RD was not observed in all groups until 25 days after X-ray irradiation. Skin temperature tended to increase in all groups regardless of irradiation or skin care. However, unlike the control group, the measured value of TEWL in the no skin care group tended to increase in the days after the X-ray irradiation. On the other hand, TEWL was increased in the skin care group compared with the no skin care group a few days after X-ray irradiation. While TEWL was constant in the moisturizer group, the skin washing groups showed an increasing tendency of TEWL and it reached a peak at 13 days after X-ray irradiation.

Conclusions

These results suggested that the decrease in skin barrier function was caused by X-ray irradiation and also that skin washing could contribute to the deterioration of skin barrier function after X-ray irradiation.

Radiodermatitis: severity, predictive factors and discontinuation of radiotherapy in patients with anal and rectal cancer

OBJECTIVE

to determine the prevalence of radiodermatitis, severity grades and predictive factors of its occurrence in patients with anal and rectal cancer followed up by the nursing consultation, and to analyze the association of severity grades of radiodermatitis with temporary radiotherapy interruption.

METHOD

a quantitative, cross-sectional and retrospective study, carried out with 112 medical records of patients with anal and rectal cancer undergoing curative radiotherapy followed up in the nursing consultation. Data were collected using a form and analyzed using analytical and inferential statistics.

RESULTS

99.1% of patients had radiodermatitis, 34.8% of which were severe. The predictive factors were female sex, age greater than 65 years, anal canal tumor, treatment with cobalt device and IMRT technique. Treatment interruption occurred in 13% of patients, associated with severe radiodermatitis.

CONCLUSION

there was a high prevalence of radiodermatitis, mainly severe, which resulted in treatment interruption.

Comparison of clinical practice guidelines on radiation dermatitis: a narrative review

PURPOSE

Radiation dermatitis (RD) is a common side effect of radiation therapy (RT). While many different treatment strategies are currently used to address RD, there is a lack of consensus and RD prophylaxis and management guidelines have remained largely unchanged over the last 10 years. This review aims to formulate unambiguous supportive care interventions by comparing RD clinical practice guidelines published between 2010 and 2021 by several organizations: Multinational Association for Supportive Care in Cancer (MASCC), British Columbia Cancer Agency (BCCA), Cancer Care Manitoba (CCMB), Oncology Nursing Society (ONS), Society and College of Radiographers (SCoR), and International Society of Nurses in Cancer Care (ISNCC).

METHODS

Areas of agreement and discordance were assessed among the MASCC, BCCA, CCMB, ONS, SCoR, and ISNCC guidelines.

RESULTS

Treatment recommendations across guidelines for acute RD and chronic RT-induced skin toxicities have been summarized. The strongest agreement among the guidelines exists for the use of topical corticosteroids, silver sulfadiazine, washing, and deodorant. All guidelines recommend the use of topical corticosteroids, and washing with water and soap is consistently supported. There is minimal consensus on an optimal dressing or barrier film for RD prophylaxis or management. MASCC weakly recommends prophylactic use of silver sulfadiazine to reduce RD, while BCCA, CCMB, and SCoR recommend its use upon signs of infection. MASCC and CCMB recommend the use of a long-pulsed dye laser to manage telangiectasia, a late effect of RT.

CONCLUSIONS

Given the extent of discordance among guideline recommendations, further research is recommended to establish optimal treatments for RD prophylaxis and management.

Efficacy of Epigallocatechin-3-Gallate in Preventing Dermatitis in Patients With Breast Cancer Receiving Postoperative Radiotherapy: A Double-Blind, Placebo-Controlled, Phase 2 Randomized Clinical Trial

Importance

Safe and effective prophylactic therapies for radiation-induced dermatitis (RID) remain an unmet need.

Objective

To determine if epigallocatechin-3-gallate (EGCG) solution reduces the incidence of RID in patients undergoing radiotherapy after breast cancer surgery.

Design, Setting, and Participants

This phase 2 double-blind, placebo-controlled randomized clinical trial enrolled 180 patients with breast cancer receiving postoperative radiotherapy at Shandong Cancer Hospital and Institute in Shandong, China, between November 2014 and June 2019. Data analysis was performed from September 2019 to January 2020.

Interventions

Participants were randomly assigned (2:1) to receive either EGCG solution (660 μmol/L) or placebo (0.9% NaCl saline) sprayed to the whole radiation field from day 1 of the radiation until 2 weeks after radiation completion.

Main Outcomes and Measures

The primary end point was incidence of grade 2 or worse RID, defined by the Radiation Therapy Oncology Group scale. The secondary end points included RID index (RIDI), symptom index, changes in the skin temperature measured by infrared thermal images, and safety.

Results

A total of 180 eligible patients were enrolled, of whom 165 (EGCG, n = 111; placebo, n = 54) were evaluable for efficacy (median [range] age, 46 [26-67] years). The occurrence of grade 2 or worse RID was significantly lower (50.5%; 95% CI, 41.2%-59.8%) in the EGCG group than in the placebo group (72.2%; 95% CI, 60.3%-84.1%) (P = .008). The mean RIDI in the EGCG group was significantly lower than that in the placebo group. Furthermore, symptom indexes were significantly lower in patients receiving EGCG. Four patients (3.6%) had adverse events related to the EGCG treatment, including grade 1 pricking skin sensation (3 [2.7%]) and pruritus (1 [0.9%]).

Conclusions and Relevance

In this randomized clinical trial, prophylactic use of EGCG solution significantly reduced the incidence and severity of RID in patients receiving adjuvant radiotherapy for breast cancer. It has the potential to become a new choice of skin care for patients receiving radiotherapy.

Nurse-Led Consultation and Symptom Burden in Patients with Head and Neck Cancer: A Comparative Analysis of Routine Clinical Data

Background: Head and neck cancer (HNC) patients experience distressing symptoms that can significantly impact their health-related quality of life (HRQoL). We analyzed the implementation of a nurse-led consultation (NLC) and explored potential associations with symptom burden in HNC patients. Methods: We retrospectively analyzed routinely collected data to describe the implementation of the nurse-led interventions and the evolution of the M.D. Anderson Symptom Inventory scores as patient-reported outcome measures (PROMs). Patients who received routine care (n = 72) were compared with patients in the NLC group (n = 62) at a radiation oncology unit between 2017 and 2019. PROMs were measured at T0 (between simulation and the first week of radiotherapy), T1 (week 3−4), and T2 (week 5−6). Results: Screening for nutrition, smoking, oral cavity status, and capacity for swallowing/chewing, but not for pain, was applied in >80% of patients in the NLC group from T0 to T1. Education (16%) and care coordination (7%) were implemented to a lesser extent. Symptom burden increased over time with no significant differences between groups. Conclusions: The nurse-led consultation was not associated with symptom burden over time. A larger implementation study including a detailed process evaluation, larger sample size, and a focus on long-term effects is needed.

Comparison of clinical practice guidelines on radiation dermatitis: a narrative review

PURPOSE

Radiation dermatitis (RD) is a common side effect of radiation therapy (RT). While many different treatment strategies are currently used to address RD, there is a lack of consensus and RD prophylaxis and management guidelines have remained largely unchanged over the last 10 years. This review aims to formulate unambiguous supportive care interventions by comparing RD clinical practice guidelines published between 2010 and 2021 by several organizations: Multinational Association for Supportive Care in Cancer (MASCC), British Columbia Cancer Agency (BCCA), Cancer Care Manitoba (CCMB), Oncology Nursing Society (ONS), Society and College of Radiographers (SCoR), and International Society of Nurses in Cancer Care (ISNCC).

METHODS

Areas of agreement and discordance were assessed among the MASCC, BCCA, CCMB, ONS, SCoR, and ISNCC guidelines.

RESULTS

Treatment recommendations across guidelines for acute RD and chronic RT-induced skin toxicities have been summarized. The strongest agreement among the guidelines exists for the use of topical corticosteroids, silver sulfadiazine, washing, and deodorant. All guidelines recommend the use of topical corticosteroids, and washing with water and soap is consistently supported. There is minimal consensus on an optimal dressing or barrier film for RD prophylaxis or management. MASCC weakly recommends prophylactic use of silver sulfadiazine to reduce RD, while BCCA, CCMB, and SCoR recommend its use upon signs of infection. MASCC and CCMB recommend the use of a long-pulsed dye laser to manage telangiectasia, a late effect of RT.

CONCLUSIONS

Given the extent of discordance among guideline recommendations, further research is recommended to establish optimal treatments for RD prophylaxis and management.

Radiodermatite: severidade, fatores preditivos e interrupção da radioterapia em pacientes com câncer anal e de reto

RESUMO Objetivo: determinar a prevalência da radiodermatite, os graus de severidade e os fatores preditivos da sua ocorrência em pacientes com câncer de canal anal e reto acompanhados pela consulta de enfermagem, e analisar a associação dos graus de severidade da radiodermatite com a interrupção temporária da radioterapia. Método: pesquisa quantitativa, seccional e retrospectiva, realizada com 112 prontuários de pacientes com câncer de canal anal e reto submetidos à radioterapia curativa acompanhados na consulta de enfermagem. Dados foram coletados por formulário e analisados empregando-se estatística analítica e inferencial. Resultados: 99,1% dos pacientes apresentaram radiodermatite, sendo 34,8% graus severos. Os fatores preditivos foram sexo feminino, idade maior que 65 anos, tumor de canal anal, tratamento com aparelho de cobalto e técnica IMRT. A interrupção do tratamento ocorreu em 13% dos pacientes, associada à radiodermatite severa. Conclusão: houve alta prevalência de radiodermatite, principalmente grau severo, que resultou em interrupção do tratamento.

Use of Chamomile Infusion to Mitigate Radiotherapy-Induced Dry Desquamation in Head and Neck Cancer Patients

Purpose:

To evaluate the effect of using a compress with Chamomilla recutita infusion in the regression of dry desquamation and in the prevention of moist desquamation in head and neck cancer patients undergoing radiotherapy.

Methods:

A prospective intervention study was carried out from May 2019 to May 2021. In total, 43 participants were included, who were instructed to apply the compress with the infusion 3 times a day, after occurrence of dry desquamation. Skin evaluation took place daily from initiation of the intervention up to the end of radiotherapy.

Results:

All the participants presented dry desquamation regression, where 65.1% (95% CI 50.1-78.1) had total regression until the end of radiotherapy, with a mean of 9 days of regression. Only 34.9% (95% CI 21.8-49.9) of the participants developed moist desquamation by the end of the radiotherapy sessions, with a mean accumulated dose of ionizing radiation of 50.9 Gy.

Conclusion:

This study highlighted the potential clinical benefits of using Chamomilla recutita in the regression of dry desquamation and in the prevention of moist desquamation.

Radiation Therapy: Understanding the Patient Experience

Radiation therapy is used as definitive or adjuvant treatment for more than half of all people receiving cancer treatment. The process for the patient spans several months and is demanding physically, mentally, and logistically. Understanding the patient experience from start to finish is important for all oncology nurses, because adherence to the treatment regimen is integral and side effects can occur even after radiation treatment has completed.

Radiodermatitis: Clinical Summary of the ONS Guidelines™ for Cancer Treatment-Related Radiodermatitis

Approximately 50%-70% of patients with cancer will receive radiation therapy. Radiodermatitis is one of the most common side effects of radiation therapy, with as many as 95% of patients experiencing some degree of skin change. Radiodermatitis can cause pain, itching, and burning and potentially has a significant impact on a patient's quality of life. If radiodermatitis becomes severe, it can cause treatment interruption. The prevalence of radiodermatitis coupled with the effect this side effect can have on quality of life prompts the need for evidence-based recommendations for management.

Radiodermatitis in Patients With Cancer: Systematic Review and Meta-Analysis

PROBLEM IDENTIFICATION

A systematic review and meta-analysis was conducted to inform the development of guidelines on the management of radiodermatitis among patients with cancer.

LITERATURE SEARCH

The authors updated a systematic review to include available literature published through September 30, 2019.

DATA EVALUATION

Two investigators assessed risk of bias using the Cochrane Collaboration risk-of-bias tool and certainty of the evidence using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach.

SYNTHESIS

The use of deodorant/antiperspirant had no effect on development of radiodermatitis. Aloe vera and emu oil were equivalent or less effective than standard care. Oral curcumin had a minimal beneficial effect. Nonsteroidal topical interventions had a minimal beneficial effect on the development of moist desquamation and relief of itching while causing a small increase for grade 2 radiodermatitis. Topical calendula increased risk for the development of radiodermatitis. Topical steroids and dressings each showed benefits to minimize the development of radiodermatitis and moist desquamation while lowering rates of patient-reported symptoms, such as pain and pruritus.

IMPLICATIONS FOR RESEARCH

Symptom management strategies for radiodermatitis among patients with cancer that are likely to be effective include topical nonsteroidals, topical steroids, and dressings.
