Fri 30th Aug 2013 Session 2 / Talk 5 11:40 – 12:00 BROOKLYN 2 RADIOTHERAPY Patries HERST • ABSTRACT Purpose: Severe acute radiation-induced skin reactions occur in a significant proportion of women who receive radiation therapy for breast cancer. We previously showed that soft silicone dressings decreased the severity of severe skin reactions by 40% when applied from the onset of erythema. Here we report the effect of a transparent silicone film on the severity of skin reactions and the incidence of moist desquamation when used from the beginning of treatment in breast cancer patients. Methods and Material: A total of 80 women were recruited from Dunedin Hospital. The breast or chest wall was randomly divided into lateral and medial halves at the start of radiation therapy treatment; one half was treated with Mepitel Film, the other half with aqueous cream. Skin reactions were assessed using the Radiation-Induced Skin Reaction Assessment Scale. Results: Mepitel Film prevented the onset of moist desquamation in all patients and decreased the severity of skin reactions by more than 80%. Patients preferred the film and found it very comfortable to wear. Conclusions: Mepitel Film prevents moist desquamation when used prophylactically

Rationale • Unavoidable side effect of external beam RT • No standard treatment • Form protective barrier • Inert • Adhere to healthy skin but do not stick to open wounds • Decrease the severity of erythema by 30% in a pilot study of 30 breast cancer patients. • (Diggelmann et al. Br J Radiol 83, 2010)
Erythema Eligibility • Post-mastectomy • No metastatic disease • No previous RT to chest • Able to attend follow up • Good performance status In-Patient Randomization Mepilex Aqueous cream 2] % MD 3] time to MD Moist desquamation Assessment Standard dressings Mepilex RISRAS • 3x a week during TMT • 1x a week for 4 weeks after TMT completion 4] time to healing Healing Stage III RCT: Mepilex Lite: Management Trial Auckland (ARO), Palmerston North, Wellington, Dunedin 80 patients enrolled, 74 analysed 1] severity
RISRAS Results of 74 mastectomy patients Decrease in overall skin reaction severity: 40% p<0.001 Paterson et al., Journal of Cancer Science and Therapy 4(11) 347-356 (2012)
Moist Desquamation Results • Decreased the area of MD by 49% • Did not affect % MD or time to MD/healing • Fall off in shower or when perspiring, do not stick well in axilla • Are not transparent: can’t see tattoos • Have a small bolus effect (0.5mm), so must be removed during RT
We need something better: Mepitel Film? • Same features as MepilexLite • Much thinner, transparent and more sticky than dressings and negligible bolus effect (0.1mm) Lateral Medial
Eligibility In-Patient Randomization • No metastatic disease • No previous RT to chest • Able to attend follow up • Good performance status 1] severity Mepitel Film Aqueous cream 2] % MD Assessment • RISRAS • 3x a week during TMT • 1x a week for 4 weeks after TMT completion Moist desquamation Stage III RCT: Mepitel Film Dunedin: 80 patients (both breast and mastectomy) Start of RT treatment
RISRAS Scores of 78 patients Decrease in severity of skin reactions: 92% P<0.001
Moist Desquamation Results No Moist Desquamation under the Film
Interesting finding Stressed patients have worse skin reactions
Conclusions Is Mepitel Film the answer to RT-induced acute skin reactions? Try it out and let me know……

Difference not due to differences in dose between Film and cream covered skin. Areas measured and compared: • Axilla (2TLDs) • IFM fold (4 TLDs) • Superior-medial (5 TLDs) • Inferior Lateral (5 TLDs)
