Quality of life in early breast cancer patients after adjuvant accelerated partial-breast irradiation (APBI) in randomized trial

Popis výsledku v původním jazyce

Accelerated partial breast irradiation (APBI) represents a valid option for adjuvant therapy of selected early breast cancer (BC). This single-institution prospective randomized study compares the health-related quality of life (HRQoL) between women treated with the highly conformal-external beam APBI technique and those with the more commonly used moderately hypofractionated whole breast irradiation (hypo-WBI). Eligible patients were women over 50 years with early BC (G1/2 DCIS &lt;= 25 mm or G1/2 invasive non-lobular luminal-like HER2 negative carcinoma &lt;= 20 mm) after breast-conserving surgery with negative margins. APBI arm consisted of 30 Gy in 5 consecutive daily fractions and WBI arm of 40 Gy in 15 fractions plus 10 Gy in 5 fractions boost to the tumor bed. Patients were requested to complete the official Czech translation of the EORTC QoL questionnaires, including QLQ-C30 and QLQ-BR45, before radiation (baseline), at the end of radiation (M0) and 1 (M1), 3 (M3), 6 (M6), 12 (M12), and 24 (M24) months after radiation. Linear regression models were used to analyze differences in HRQoL between the arms. The 85 enrolled patients exhibited no differences in HRQoL scores between the two arms at baseline. Patients in the APBI arm reported more favorable global health status at M6 (p = 0.055). Other functional scales showed a decrease in the WBI arm at M0 (p = 0.027 for physical functioning). During radiation, symptoms scores increased. Significant between-group differences were observed for the pain (p = 0.002), systemic therapy side effects (p = 0.004), and breast symptoms (p &lt; 0.001) scales at M0, with higher scores in the WBI arm. During follow-up, scores on symptoms scales returned to at least the baseline values. Early BC patients treated with APBI showed non-inferior short-term and late HRQoL outcomes compared to hypo-WBI. In addition to previous findings regarding toxicity, promising pain and breast symptoms results, suggest that APBI should be strongly considered as a treatment option for selected low-risk patients. Trial registration NCT06007118, August 23, 2023 (retrospectively registered).
