Improved long-term patient-reported health and well-being outcomes of early-stage breast cancer treated with partial breast proton therapy



Improved long-term patient-reported health and well-being outcomes of early-stage breast cancer treated with partial breast proton therapy



Cancer Medicine 2018



Because early-stage breast cancer can be treated successfully by a variety of breast-conservation approaches, long-term quality of life (QoL) is an important consideration in assessing treatment outcomes for these patients. This study compares patient-reported QoL outcomes among women with stage 0-2 disease treated via lumpectomy followed by whole breast irradiation (WBI) or partial breast proton irradiation (PBPT). In this cross-sectional study, 129 participants evaluated QoL several years post-treatment by responding to subjective instruments, including established scalar questionnaires and self-report measures. Responses were averaged between the two groups. At 6.5 years (median) postdiagnosis, participants' demographic, and clinical characteristics were similar. Patient-reported outcomes were reported as mean scale scores for the two groups, all displaying significant differences favoring PBPT, including: cosmetic breast cancer treatment outcome scale (BCTOS) (PBPT mean 1.45, WBI mean 1.88, P < 0.001); breast pain (PBPT mean 1.30, WBI mean 1.67, P < 0.05); breast texture (BPT mean 1.44, WBI mean 1.91, P < 0.001); clothing fit (PBPT mean 1.06, WBI 1.46, P < 0.001); fatigue (PBPT mean 2.24, WBI mean 3.77, P < 0.002); impact of daily life fatigue on personal relations (OBPT mean 0.83, WBI mean 2.15, P < 0.001); and self-consciousness (appearance dissatisfaction) (PBPT mean 1.38, WBI mean 1.77, P < 0.004). Patients' responses suggest that PBPT is associated with improved overall QoL compared to standard whole breast treatment. These self-perceptions are reported by patients who are 5-10 years post-treatment, and that PBPT may enhance QoL in a multitude of interrelated ways.
