Palliation of Ulcerative Breast Lesions with Radiation

Abstract

Background/aim: Patients with advanced breast cancer may experience ulcerative breast lesions. Breast cancer with ulcerative lesions has been shown to severely affect a patient's quality of life (QoL). The role of palliative radiation therapy (RT) in the management of ulcerative breast lesions needs to be further explored.

Patients and methods: We retrospectively reviewed the RT records for all patients who underwent palliative RT for breast cancer at our urban academic medical center. A total of 13 patients were identified, and we herein report their demographics, treatment characteristics, and clinical outcomes.

Results: The mean age of the patients receiving palliative RT for ulcerative breast cancer was 64 years. All patients had stage IV disease when they were evaluated for RT. The mean radiation dose received for palliative RT was 27.54 Gy in 11 fractions, with a median dose of 30 Gy in 15 fractions. Six (46%) patients had received prior RT to the same breast, with a median dose of 59.5 Gy in 31 fractions. Among these six patients, the average interval between initial RT and ulceration was 69.5 months. The median overall survival for the whole patient cohort since ulceration was 5 months and the mean survival did not differ between patients with previous history of RT and RT-naïve patients (4.50 vs. 4.57; p=0.95). Six out of the nine (69%) patients who received 30 Gy or more reported clinical improvement, whereas none of the four patients who received less than 30 Gy reported any benefit. There were no radiation-associated toxicities reported by patients.

Conclusion: These data suggest that palliative RT (≥30 Gy) is an efficacious treatment for ulcerative breast cancer with minimal toxicity. Prior RT should not be a contraindication, as patients with previous history of RT have similar low toxicity rates compared to RT-naïve patients.
