NCT07755553

Brief Summary

This study evaluated a mushroom extract-containing topical cosmetic formulation for skin care in women receiving radiotherapy to the breast after breast-conserving surgery. Participants were randomly assigned to use either the investigational cosmetic formulation or usual moisturizing cosmetic care. The assigned cosmetic product was applied to intact skin of the breast twice daily, beginning approximately 15 days before radiotherapy, continuing throughout the approximately 3-week radiotherapy period, and ending 1 month after radiotherapy. Participants were instructed not to apply the cosmetic product during the 3 to 4 hours before a radiotherapy session. Skin condition was assessed before use of the assigned product, at the start and end of radiotherapy, and 1 month after radiotherapy. Assessments included skin hydration, transepidermal water loss, erythema, pigmentation, dermatologic evaluation, photographs, participant-reported product experience, and adverse events. The study compared changes over time between the investigational formulation and usual cosmetic skin care.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in skin hydration

    Skin hydration of the irradiated breast was measured in arbitrary units using the Corneometer® CM 825. Measurements were obtained from predefined breast regions. The outcome was the change from baseline and the trajectory of skin hydration over the study visits. Higher values indicate greater stratum corneum hydration. Changes over time were compared between the mushroom extract-containing topical cosmetic formulation and usual moisturizing cosmetic care.

    Baseline, approximately 15 days before radiotherapy; start of radiotherapy; end of radiotherapy, approximately Day 21; and 1 month after radiotherapy

Secondary Outcomes (6)

  • Change from baseline in transepidermal water loss

    Baseline, approximately 15 days before radiotherapy; start of radiotherapy; end of radiotherapy, approximately Day 21; and 1 month after radiotherapy

  • Change from baseline in skin erythema index

    Baseline, approximately 15 days before radiotherapy; start of radiotherapy; end of radiotherapy, approximately Day 21; and 1 month after radiotherapy

  • Change from baseline in skin melanin index

    Baseline, approximately 15 days before radiotherapy; start of radiotherapy; end of radiotherapy, approximately Day 21; and 1 month after radiotherapy

  • Severity of radiation-induced skin reactions

    Baseline, approximately 15 days before radiotherapy; start of radiotherapy; end of radiotherapy, approximately Day 21; and 1 month after radiotherapy

  • Participants with adverse events

    From first product application, approximately 15 days before radiotherapy, through 1 month after completion of radiotherapy

  • +1 more secondary outcomes

Study Arms (2)

Mushroom extract-containing topical cosmetic formulation

EXPERIMENTAL

Participants applied the investigational mushroom extract-containing topical cosmetic formulation to intact skin of the breast scheduled for irradiation twice daily. Application began approximately 15 days before radiotherapy, continued throughout the approximately 3-week radiotherapy period, and continued until 1 month after radiotherapy. Participants were instructed not to apply the formulation during the 3 to 4 hours before a radiotherapy session and not to use another cosmetic product on the study area.

Other: Mushroom extract-containing topical cosmetic formulation

Usual moisturizing cosmetic care

ACTIVE COMPARATOR

Participants used a moisturizing cosmetic product selected from products recommended as part of routine clinical practice. The product was applied to intact skin of the breast scheduled for irradiation twice daily, beginning approximately 15 days before radiotherapy, continuing throughout the approximately 3-week radiotherapy period, and ending 1 month after radiotherapy. Participants were instructed not to apply the product during the 3 hours before radiotherapy and not to use another cosmetic product on the study area.

Other: Usual moisturizing cosmetic care

Interventions

A multi-ingredient topical cosmetic cremigel containing extracts of Cordyceps sinensis, Ganoderma lucidum, and Hericium erinaceus, together with moisturizing and skin-conditioning ingredients. Participants applied the required amount with a gentle massage to intact skin of the breast twice daily, beginning approximately 15 days before radiotherapy, continuing throughout the approximately 3-week radiotherapy period, and ending 1 month after radiotherapy. The formulation was not applied during the 3 to 4 hours before a radiotherapy session. No other cosmetic product was permitted on the study area.

Mushroom extract-containing topical cosmetic formulation

A nonstandardized moisturizing cosmetic product selected by the participant from products recommended by the clinical staff as part of routine skin care during breast radiotherapy. Participants applied the selected product to intact skin of the breast twice daily, beginning approximately 15 days before radiotherapy, continuing throughout the approximately 3-week radiotherapy period, and ending 1 month after radiotherapy. The product was not applied during the 3 hours before a radiotherapy session. No other cosmetic product was permitted on the study area.

Usual moisturizing cosmetic care

Masking Details
Participants and the principal investigator were aware of the assigned cosmetic regimen. Dermatologic and instrumental outcome assessments were performed by evaluators who were intended to remain unaware of treatment allocation. The same dermatologist performed the dermatologic assessments, and the same trained evaluator performed the instrumental measurements throughout the study.

Intervention Model
PARALLEL
Model Details: Participants were randomized in a 1:1.5 ratio to one of two parallel groups: a mushroom extract-containing topical cosmetic formulation or usual moisturizing cosmetic care. Both groups used their assigned topical cosmetic regimen from approximately 15 days before breast radiotherapy until 1 month after completion of radiotherapy.
