Xenogeneic platelet-rich plasma lotion for preventing acute radiation dermatitis in patients with breast cancer undergoing radiotherapy: An open-label, randomized controlled trial

Background

Breast cancer patients experience acute radiation dermatitis (ARD) during radiation therapy (RT). This study investigated the prophylactic effect of a newly developed xenogeneic platelet-rich plasma (PRP) lotion on ARD for breast cancer patients.

Methods

This study enrolled patients with ductal carcinoma in situ and early-stage invasive breast cancers after breast-conserving surgery. Hypofractionated whole-breast RT (42.5 Gy in 16 fractions) followed by tumour bed boost (10 Gy in 5 fractions) was used. The patients were randomly assigned to XONRID® gel (n = 48) or PRP lotion (n = 52) groups. We recorded the skin toxicity weekly during RT and at 2 weeks after RT. ARD was graded on the basis of the RTOG definition by two senior radiation oncologists, and the numerical rating scale (NRS) for pain and Dermatology Life Quality Index (DLQI) were subjectively scored by patients.

Results

Grade 3-4 ARD was noted in three (6 %) patients in the XONRID® gel group and no patients in the PRP lotion group (p < 0.001). One patient did not complete RT in the XONRID® gel group due to intolerable pain and refused to complete the weekly questionnaires and follow-ups. Compared with the XONRID® gel group, the PRP lotion group had significantly reduced and delayed progression of mean ARD (p = 0.001), lower mean NRS for pain value (p = 0.021) and lower mean DLQI (p = 0.048).

Conclusions

This randomized controlled trial is the first to use xenogeneic PRP lotion for ARD prevention. This lotion has prophylactic effects against ARD and thus improves quality of life of patients undergoing RT.

Comparison of the efficacy among different interventions for radiodermatitis: A Bayesian network meta‑analysis of randomized controlled trials

BACKGROUND

Radiation dermatitis (RD) is a prevalent and difficult-to-manage consequence of radiation therapy (RT). A variety of interventions have been proven effective in preventing and treating RD. However, the optimal approach remains unclear. This network meta-analysis (NMA) conducted a comparison and ranking of the effectiveness and patient-reported outcomes (PROs) of the interventions currently utilized in RD.

METHODS

PubMed, Web of Science, Embase, and Cochrane Library were searched to identify pertinent randomized controlled trials (RCTs) focused on the prevention and treatment of RD. The primary outcome measures included the incidence of grade≥2 RD (i.e., percentage of moist desquamation) and RD score. The secondary outcome measures encompassed patients' subjective assessment scores of pains, itching and burning sensations.

RESULTS

Our meta-analysis encompassed 42 studies and 4884 participants. Regarding the primary outcomes, photobiomodulation treatment (PBMT) ranked first in surface under curve cumulative ranking area (SUCRA:0.92) for reducing the incidence of grade≥2 RD. It demonstrated a significant difference when compared to Trolamine (OR 0.18,95%CrI 0.09-0.33) and Xonrid® (OR 0.28,95%CrI 0.12-0.66). Mepitelfilm (SUCRA: 0.98) achieved the highest rank in reducing the RD score, demonstrating superiority over StrataXRT® (MD -0.89, 95% CrI -1.49, -0.29). Henna (SUCRA: 0.89) demonstrated the highest effectiveness in providing pain relief, with a significant difference compared to Hydrofilm (MD -0.44, 95% CrI -0.84, -0.04) and Mepitelfilm (MD -0.55, 95% CrI -0.91, -0.19). Hydrofilm (SUCRA: 0.84) exhibited the fewest itching sensations, demonstrating superiority over Mepitelfilm (MD -0.50, 95% CrI -0.84, -0.17). No statistically significant difference was observed among various interventions in the assessment of burning sensations.

CONCLUSION

PBMT and Mepitelfilm demonstrated better efficacy in reducing the incidence of grade≥2 RD and RD score, respectively. In terms of PROs, Henna and Hydrofilm had fewer complaints in pain and itching sensations, respectively. However, studies with larger sample size on different interventions are warranted in the future.

Interventions to improve quality of life in patients with head and neck cancers receiving radiation therapy: a scoping review

BACKGROUND

Quality of life (QOL) is impaired in patients with head and neck cancers (HNC) due to illness and treatment-associated morbidity. Although there is evidence from the studies on interventions' role in improving QOL receiving radiation therapy, these are not systematically synthesised. In this scoping review, we searched and synthesised the evidence on interventions to improve the QOL and its impact among patients with HNCs.

METHODS

This scoping review was conducted using the framework proposed by Arksey and O'Malley, and the extensions suggested by Levac et al. were incorporated. Two reviewers independently searched four electronic databases using key thesaurus and free-text terms, and the data was extracted, tabulated, synthesised and reported as categories.

RESULTS

Seventy-nine papers reported various interventions of diverse nature such as pharmacological, physical, nutritional, complementary and alternative therapies, psychosocial, oral care related, laser and photobiomodulation therapies, rehabilitative, educational, technology-based, surgical, device-related and nurse lead interventions. Most studies reported clinically meaningful impact of interventions on QOL, although the outcome differences were often statistically insignificant. Few studies reported a combination of interventions to address the multidimensional concerns faced by patients with HNCs. None of the studies examined the impact of interventions on QOL among long-term survivors of HNCs.

CONCLUSION

As QOL concerns in patients with HNCs are multifaceted, more extensive studies with complex multi-component interventions and robust research designs are warranted.

Do Barrier Films Impact Long-Term Skin Toxicity following Whole-Breast Irradiation? Objective Follow-Up of Two Randomised Trials

Purpose: Hydrofilm, a polyurethane-based barrier film, can be used to prevent acute radiation dermatitis (RD) in adjuvant whole-breast irradiation (WBI) for breast cancer. This cost-effective prophylactic measure is currently being recommended to a growing number of patients, yet long-term safety data and its impact on late radiation-induced skin toxicity such as pigmentation changes and fibrosis have not been investigated. Methods: We objectively evaluated patients who were previously enrolled in either of two intrapatient-randomised (lateral versus medial breast halve) controlled trials on the use of Hydrofilm for RD prevention (DRKS00029665; registered on 19 July 2022). Results: Sixty-two patients (47.7% of the initial combined sample size) provided consent for this post-hoc examination, with a median follow-up time (range) of 58 (37-73) months. Following WBI, there was a significant increase in yellow skin tones of the entire breast when compared to baseline measurements before WBI (p < 0.001) and a significant increase of cutis, subcutis, and oedema thickness (p < 0.001, p < 0.001, and p = 0.004, respectively). At follow-up, there were no significant differences in either pigmentation changes or skin fibrosis between the Hydrofilm and standard of care breast halves. Conclusion: These data suggest that Hydrofilm can be safely used in the context of acute RD prevention, without affecting late side effects, supporting its widespread use.

Cicaderma® in radiation-related dermatitis of breast cancer: Results from the multicentric randomised phase III CICA-RT

Background and purpose

To prevent the occurrence of grade ≥ 2 radiodermatitis after post-operative breast irradiation in patients with non metastatic breast cancer.

Methods

This prospective randomised open-label multicenter study allocated patients from 3 French institutions, ≥18 years, requiring postoperative radiotherapy for histologically proven, early-stage (non-metastatic) unilateral breast adenocarcinoma or in situ breast cancer, with R0 or R1 post-operative status, to receive hygiene rules, associated with either Cicaderma® (Arm A), or preventive treatment according to the investigator preference (mainly hyaluronic acid (ialuset®), essential oils, or water spray, or no medication (Arm B). The primary outcome was to compare the efficacy of Cicaderma® versus local standard management in preventing the occurrence of grade ≥ 2 radiodermatitis. Main secondary objectives include Cicaderma® impact on radiotherapy discontinuation and on skin toxicity (pruritus), pain, quality of life, satisfaction.

Results

The CICA-RT study enrolled from June 2020 to April 2021, 258 women with a median age of 61 (22-91) years in 3 institutions. Patients received either Cicaderma® (A: N = 130) or standard practice (B: N = 128). In the 123 patients who initiated radiotherapy in each arm, 95 (77%, 95%CI 68.8%-84.3%) patients did not develop grade ≥ 2 dermatitis. Sensitivity and per-protocol analyses confirmed the absence of differences between arms.

Conclusion

This prospective study did not meet its primary endpoint of superiority of Cicaderma® over routine practice skin care in terms of prevention of acute radioinduced dermatitis of grade 2 or higher. However, Cicaderma® showed a significant decrease in the occurrence of pruritus with less patients reporting at least once grade ≥ 2 pruritus (A: N = 38, 31%; B: N = 58, 47%; p = 0.009).ClinicalTrials.gov identifier NCT04300829.

MASCC clinical practice guidelines for the prevention and management of acute radiation dermatitis: part 1) systematic review

Acute radiation dermatitis (ARD) commonly develops in cancer patients undergoing radiotherapy and is often characterized by erythema, desquamation, and pain. A systematic review was conducted to summarize the current evidence on interventions for the prevention and management of ARD. Databases were searched from 1946 to September 2020 to identify all original studies that evaluated an intervention for the prevention or management of ARD, with an updated search conducted in January 2023. A total of 235 original studies were included in this review, including 149 randomized controlled trials (RCTs). Most interventions could not be recommended due to a low quality of evidence, lack of supporting evidence, or conflicting findings across multiple trials. Photobiomodulation therapy, Mepitel® film, mometasone furoate, betamethasone, olive oil, and oral enzyme mixtures showed promising results across multiple RCTs. Recommendations could not be made solely based on the published evidence due to limited high-quality evidence. As such, Delphi consensus recommendations will be reported in a separate publication.

Photobiomodulation therapy for the prevention of acute radiation dermatitis: a systematic review and meta-analysis

PURPOSE

Approximately 95% of patients undergoing radiotherapy (RT) experience radiation dermatitis (RD). Evidence has suggested that photobiomodulation therapy (PBMT) can stimulate skin renewal and minimize RD. The aim of the present paper was to investigate the efficacy of PBMT in RD prevention through a comprehensive literature review.

METHODS

A literature search of Ovid MEDLINE, Embase, and Cochrane databases was conducted from 1980 to March 2021 to identify RCT on the use of PBMT for RD prevention. Forest plots were developed using RevMan software to quantitatively compare data between studies.

RESULTS

Five papers were identified: four in breast and one in head and neck cancer patients. Patients receiving PBMT experienced less severe RD than the control groups after 40 Gray (Gy) of RT (grade 3 toxicity: Odds Ratio (OR): 0.57, 95% CI 0.14-2.22, p = 0.42) and at the end of RT (grade 0 + 1 vs. 2 + 3 toxicity: OR: 0.28, 95% CI 0.15-0.53, p < 0.0001). RT interruptions due to RD severity were more frequent in the control group (OR: 0.81, 95% CI 0.10-6.58, p = 0.85).

CONCLUSION

Preventive PBMT may be protective against the development of severe grades of RD and reduce the frequency of RT interruptions. Larger sample sizes and other cancer sites at-risk of RD should be evaluated in future studies to confirm the true efficacy of PBMT, also in preventing the onset of RD and to finalize a standardized protocol to optimize the technique. At present, starting PBMT when RT starts is recommendable, as well as performing 2 to 3 laser sessions weekly.

Topical Prevention of Radiation Dermatitis in Head and Neck Cancer Patients: A Network Meta-analysis

BACKGROUND/AIM

Head and neck cancer is a major malignancy worldwide. The treatment strategy for head and neck cancer usually involves radiotherapy. The main side effect of radiotherapy is radiation dermatitis. Thus, determining the most effective topical regimen for the prevention of radiation dermatitis in head and neck cancer patients is a critical issue.

PATIENTS AND METHODS

PRISMA-NMA guidelines were used in this network meta-analysis. We included only randomized control trials. A random effects model was used. Heterogeneity was evaluated by I2 and Cochran's Q tests.

RESULTS

We included a total of 1,304 patients in the network meta-analysis. Among them, olive oil was the only effective regimen when compared with usual care (OR=0.18, 95%CI=0.03-0.95). The I2 value was 56%. The test of heterogeneity yielded a p-value of 0.10.

CONCLUSION

Olive oil was the most effective regimen for the prevention of radiation dermatitis.
