CLINICAL QUESTION

What is the best available evidence for barrier films for preventing and treating radiation dermatitis in people undergoing radiation therapy for cancer?

SUMMARY

Radiation dermatitis (RD) is an acute skin reaction that occurs as a result of radiotherapy used to treat a range of different cancers. Severity of symptoms ranges from erythema to dry desquamation (dry flaky skin with itching) to moist desquamation (serous exudate, oedema and blistering). Level 1 evidence1-3 reporting effectiveness of barrier films for preventing RD. Some studies2-4 showed statistically significant reductions in severity of RD and reduction in patient-reported symptoms.; however, the volume of evidence was small. Largest effect was achieved with a silicone-based barrier film forming gel dressing that was associated with a 41% reduction in risk of grade 2 RD.4 Level 1 and 3 evidence4, 5 failed to demonstrate a benefit in using a barrier film to treat existing RD.

CLINICAL PRACTICE RECOMMENDATIONS

All recommendations should be applied with consideration to the wound, the person, the health professional and the clinical context.

A barrier film could be applied as prophylactic protection to reduce the incidence of radiation dermatitis (Grade B).

There is no strong evidence to support the use of a barrier film for healing existing radiation dermatitis.

SOURCES OF EVIDENCE

This summary was conducted using methods published by the Joanna Briggs Institute.6-8 The summary is based on a systematic literature search combining search terms related to radiation dermatitis/radiodermatitis and wound dressings and barrier films. Searches were conducted in Embase, Medline, Pubmed, the Cochrane Library and Google Scholar for evidence published up to January 2021 in English. Levels of evidence for intervention studies are reported in the table below.

BACKGROUND

Radiation dermatitis is a common side effect of radiotherapy, which is a type of therapy delivered in the management of cancer. Radiation causes damage to epithelial cells and underlying structures of the skin, usually commencing early during radiotherapy and persisting up to six months following radiotherapy.11, 12 The severity of RD is related to the dose and regimen of radiation and the area of skin over which radiotherapy is administered,11-13 increasing when cell destruction occurs faster than normal cell reproduction. In early stages of RD the skin becomes warmer, itchy and erythema may present. As cumulative exposure to radiation increases, old skin becomes dry and flaky (referred to as dry desquamation). When the rate of new skin cell production cannot replace shedding cells the epidermis breaks down, becomes oedematous and exudate is present (referred to as moist desquamation).12 Pain, skin warmth, pruritus, burning sensations are reported by people experiencing RD.14 Consistent with outcome measures reported in the evidence, when referring to ‘grade’ of RD this evidence summary uses the Radiation Therapy Oncology Group (RTOG) scale for categorising the severity acute of RD.15

Barrier films are applied to the skin in a spray, liquid or gel and dry to form a protective film coating the skin that protect the skin and wound.14

CLINICAL EVIDENCE

Barrier film for preventing radiation dermatitis

Three studies reported on the same no-sting barrier film product for preventing RD. The barrier film was compared to Sorbolene cream (n = 61, participants acted as own controls) in an RCT conducted with women undergoing radiotherapy for breast cancer. Sorbolene was applied twice daily and the barrier film was applied 2—3 times weekly, with treatments continuing until either moist desquamation occurred or two weeks after radiotherapy completion. The barrier film was statistically significantly superior based on RTOG scores (p = 0.005) and pruritus (p = 0.011). Pain scores were not statistically significantly difference2 (Level 1).

In a multi-arm RCT, participants acted as their own controls to compare the barrier film to corticosteroid (n = 17 in arm) or to no treatment (n = 13 in arm). Compared to topical corticosteroids, people using the barrier film showed no statistically significant difference in time to occurrence of grade 1 RD (32.4 days versus 28.4 days, n = 0.072). However, the barrier film was inferior to corticosteroid for time until occurrence of grade 2 RD (44.5 days versus 53.4 days, p = 0.002). The barrier film was not statistically different to no treatment for time to occurrence of grade 1 RD (32.5 versus 29.4, p = 0.079) or grade 2 RD (44.2 versus 46.6, p = 0.196). There was also no significant difference in either arm for pain outcomes1 (Level 1).

In a third RCT, the barrier film was compared to a regimen of skin hygiene, moisturiser and topical corticosteroid (n = 79 analysed, participants acted as own controls). Skin regions receiving the barrier film were statistically significantly less likely to experience sensitivity (p < 0.001) , pain (p < 0.001), burning sensation (p = 0.005) or oedema (p = 0.005)3 (Level 1).

One RCT (n = 189)4 reported on a silicone-based barrier film forming gel dressing;** for preventing RD. The comparator group received Sorbolene cream. The participants receiving the barrier film forming gel had four weeks free from RD compared to a median of three weeks for Sorbolene, equating to a 41% risk reduction for grade 2 RD4 (Level 1).

Barrier film for treating existing radiation dermatitis

Two studies4, 5 reported on a silicone-based barrier film forming gel4  dressing;†† one of these studies compared the barrier film to Sorbolene cream4 (Level 1) and the second undertook an observational assessment5 (Level 3). The observation study (n = 54) found that there was no statistically significant improvement in dry desquamation (p = 0.40) or moist desquamation (p = 0.589)5 (Level 3). In the larger RCT (n = 189),4 mean RD severity grade over a maximum of four weeks was lower in the barrier film-forming dressing group (mean = 2.4, 95% CI 2.2 to 2.6 versus mean = 2.7, 95% CI 2.5 to 3.0, p = 0.002), and the dressing was associated with slower progression to RD severity of grade 3 (6 weeks versus 5 weeks)4 (Level 1). The observational study5 showed a statistically significant 16.9% improvement in clinical condition (p < 0.05) using the Radiation-Induced Skin Reaction Assessment Scale (RISRAS) score, with improvement noted in erythema, pain, pruritus, burning, inflammation and skin hydration5 (Level 3). However, the RCT4 found no statistically significant difference in scores for pruritus, pain or quality of life4 (Level 1).

The findings from these two studies4, 5 showed weak evidence that this silicone-based barrier film forming gel dressing was associated with statistically significantly faster healing of RD, although the differences may not be clinically significant. A small amount of evidence5 suggested that progression to more severe RD might be delayed, and evidence4, 5 was conflicting on the impact of this product on associated skin signs and symptoms.

CONSIDERATIONS FOR USE

  • Selection of a barrier film should be made with consideration to the goals of care, which may differ based on severity of the person’s RD.9
  • Silicone-based barrier film forming gel dressing does not need to be removed prior to undergoing radiation therapy.10
  • Ability for a dressing to manage exudate is a consideration for people with moist desquamation.9
  • The average cost of a no-sting barrier film regimen was comparable to treatment with Sorbolene in Australia in 2004.2
