Brief Summary:
Breast cancer patients undergoing adjuvant radiotherapy commonly experience radiation-induced skin reactions which adversely impact quality of life. Importantly, patients receiving chest wall radiation or patients with large breasts are more likely to have worse skin reactions. In the last decade, there have been no significant advances in preventing or treating radiation-induced skin toxicities. In response to the lack of evidence, Sunnybrook investigators previously conducted a pilot study (REB #294-2018) of Mepitel Film and preliminary results showed improvements in high grade skin reactions. Mepitel Film has not been widely adopted in North America as more evidence is needed. The validate the efficacy of the film compared to the standard of care, a study testing the efficacy of the film is proposed. In the study, 216 patients will be randomized (2:1) to receive either the film or the institution's current skin treatments and all patients will have their skin assessed.

Breast Cancer Radiation Dermatitis Device: Mepitel Film Phase 3

Detailed Description:

Breast cancer patients undergoing adjuvant radiotherapy commonly experience radiation-induced skin toxicities which adversely impact patients' quality of life. These skin toxicities may present in the form of acute reactions including erythema, pruritus or moist desquamation and late toxicities in the form of hyperpigmentation or fibrosis. The development of severe skin toxicities may result in treatment interruptions or increase the risk of reconstructive complications. Importantly, patients receiving radiotherapy to the chest wall or patients with larger breast size are more likely to have more severe skin reactions. In the last few decades, there have been no significant advances in preventing or treating radiation-induced skin toxicities.

A phase III randomized trial was conducted by Herst et al. (n=78) in New Zealand which showed that the prophylactic use of Mepitel Film prevented moist desquamation (26% vs. 0%, p < 0.001) and reduced skin reaction severity by 92% (p < 0.001) compared to skin treated only with aqueous cream. Mepitel Film has not been adopted in routine practice in North America as more convincing proof may be needed from international multi-centre trials to influence changes in standard clinical practice guidelines. A phase II feasibility study has recently been completed at Sunnybrook Odette Cancer Centre and the preliminary results have shown reductions in severe skin reactions.

Mayo Clinic has also completed a phase II pilot study which, like the feasibility study conducted at our centre, yielded promising results. The Alliance trial group in the US is planning for a phase III multi-centre trial for post-mastectomy patients receiving conventional radiation treatment. As the Alliance trial is only enrolling post-mastectomy patients receiving conventional radiotherapy, our study will additionally investigate outcomes for post-mastectomy patients receiving hypofractionated radiation treatment. Additionally, the investigators will be enrolling patients with large breasts [bra size 36 in and/or C cup or greater] as these patients are at known risk for developing increased acute skin toxicities

A randomized controlled trial is a critical next step in establishing whether Mepitel Film reduces acute and long-term skin toxicity in post-mastectomy and large breasted patients and in order for it to become standard of care in breast radiotherapy. This study plans to enroll 216 patients in a 2:1 ratio (2 Mepitel Film: 1 institutional standard of care).

The primary objective is to compare the efficacy of Mepitel Film versus the institutional standard of care in reducing the severity of radiation dermatitis in patients undergoing whole breast or chest wall radiotherapy. Secondary objectives include an evaluation of patient-reported and healthcare professional (HCP)-reported skin toxicities including moist desquamation with the use of Meptiel Film.

Radiation oncologists will first introduce the study to their patients in their breast clinic, showing a sample of the product and also pictures from the trial conducted in New Zealand. Patients if interested may be provided a patient information sheet to review at home. Then, patients will be approached by a CRA at their radiation planning appointment to review all information and obtain informed consent.

For patients randomized to the Mepitel Film arm, patients will receive the film for the entire duration of treatment. Radiation treatment will be delivered as prescribed by the treating radiation oncologist irrespective of study arm and may include a variety of techniques and beam modifiers.

Arm Intervention/treatment
Experimental: Mepitel Film Arm
Patients randomized to the Mepitel Film arm will receive the film for the entire duration of their radiation treatment and will be worn up to 2 weeks after completion of radiotherapy.
Device: Mepitel Film
Mepitel® Film is a thin, soft and conformable transparent film dressing with Safetac®, offering protection for vulnerable skin.

No Intervention: Standard of Care Arm
Patients randomized to the Standard of Care arm will be instructed to use the institutional standard of care skin treatments for the entire duration of their radiation treatment and up to 2 weeks after completion of radiotherapy.



Primary Outcome Measures :
  1. Number of participants with treatment-related radiation-induced skin toxicity as assessed by the CTCAE v.5.0. [ Time Frame: Within 3 months following radiation ]
    Number of participants with radiation-induced skin toxicities as assessed by the Common Terminology Criteria for Adverse Events v.5.0, comparing changes in the treated versus non-treated breast or chest wall from baseline to weekly during radiation treatment and once a week for 6 weeks post-treatment.


Secondary Outcome Measures :
