Is this trial a fit for you?

Likely a good fit

Adult women with pathologically confirmed breast cancer who have had mastectomy and are scheduled for post-mastectomy radiotherapy.

Probably not a fit

Patients with contraindications to the study skin care products or those not receiving the specified radiotherapy regimen may not benefit.

What this trial studies

This Phase 2 interventional trial compares three skin care strategies—Mometasone Furoate 1% cream, Mepitel Film, and chlorhexidine body cleansing, with or without mupirocin—to prevent dermatitis from post-mastectomy radiation therapy. Eligible participants are adults with pathologically confirmed breast cancer who have had mastectomy and are planned for comprehensive radiotherapy to the chest wall and regional nodes. The study uses randomized or parallel assignment to assess which approach most effectively reduces skin reactions, with safety and tolerability monitored throughout treatment. Location is MSK facilities in New Jersey, including Basking Ridge, Monmouth, and Bergen sites.

Why it matters

Potential benefit: If successful, participants and future patients could experience fewer radiation-related skin reactions and improved comfort during therapy.

How similar studies have gone: Prior studies in skin care for radiation dermatitis have shown varying success; this trial applies three standard approaches in a post-mastectomy setting.

Exclusion Criteria:

* Patients with indication for escalated skin dose (dermal invasion, skin involvement, positive surgical margin).

* Comorbid conditions:

  o Active infection requiring parenteral antibiotic(s)
* Concomitant Medications:

  o Concurrent systemic therapy during the course are not allowed, including cytotoxic chemotherapy, immunotherapy, and targeted therapy. Last dose of these agents must be delivered at least 2 weeks prior to start of radiotherapy and not to be restarted until at least 2 weeks following completion of radiotherapy. Endocrine therapy, pembrolizumab, Herceptin, Perjeta, and Kadcyla are allowed. Concurrent oral steroid medications are not allowed.
