KeraStat Skin Therapy in Treating Radiation Dermatitis in Patients With Newly Diagnosed Stage 0-IIIA Breast Cancer

PRIMARY OBJECTIVES:

I. To obtain a preliminary estimate the incidence of early adverse skin reaction (EASR)
during radiation therapy (RT) and up to two months post RT after the application of the
cosmetic cream KeraStat Skin Therapy during RT in breast cancer patients in a pilot study.

SECONDARY OBJECTIVES:

I. To associate personal characteristics (e.g., race/ethnicity, age, hormone therapy,
smoking status, comorbidities, breast size) and treatment characteristics (e.g., RT dose) to
incidence of EASR at any time point.

OUTLINE:

Patients apply KeraStat Skin Therapy topically twice daily (BID) during radiation therapy.

After completion of study treatment, patients are followed up at 1 and 2 months.

Inclusion Criteria:

- Newly diagnosed with breast carcinoma, stage 0-IIIA (including ductal carcinoma in

- Plan to receive adjuvant radiation to the whole breast or chest wall +/- regional
lymph nodes

- Total dose >= 40Gy

- Dose per fraction >= 1.8 use of 2-dimensional (2D), 3-dimensional (3D) conformal, or
intensity-modulated radiation therapy (IMRT) treatment techniques allowed; skin
sparing IMRT patients excluded; a daily fraction of 2.7 Gy to the whole breast is
suggested for hypofractionated regimens

- Concurrent and sequential boost techniques are allowed for both standard and
hypofractionated regimens

- Adjuvant hormonal therapy will be allowed prior to, during and/or after RT at the
discretion of a medical oncologist

- Targeted therapies such as Herceptin will be allowed prior to, during, and/or after
RT at the discretion of the medical oncologist

- Patients who are able and willing to sign protocol consent form

Exclusion Criteria:

- Prior radiation to the involved breast or chest wall

- Concurrent chemotherapy; (patients may receive chemotherapy prior to radiation or
following radiation at the treating physician's discretion)
