Clinical Trial Summary

The adjuvant radiotherapy (RT) of the early-stage breast cancer patients as local treatment aims to eliminate the potential microscopic residual disease in the surgery bed or satellites in its neighborhood. Nowadays accelerated partial breast irradiation (APBI) is recommended for highly selected patients. This prospective randomized study compares the targeted external beam APBI with commonly used accelerated whole-breast irradiation (WBI) in terms of feasibility, safety, tolerance, and cosmetic effects. It is designed as non-inferiority trial and its aim is to increase the level of evidence for establishment of external beam APBI in indicated patients into daily clinical practice.

Description:

Early-stage breast cancer patients after partial mastectomy are screened for eligibility. The inclusion criteria are age ˃ 50 years, non-lobular carcinoma histology, size ≤ 2 cm, negative margins ≥ 2 mm, L0, ER-positive, HER-2 negative. Enrolled patients are equally randomized into two arms according to radiotherapeutic regiment - external beam APBI (5× 6 Gy) and accelerated whole breast irradiation with the boost (15× 2,67Gy + 5× 2Gy). The follow-up visits are planned at the end of RT and 1, 3, 6, 9, and 12 months after radiation, in the second year every 4 months and then every 6 months. Cosmetics results and toxicity are evaluated using questionnaires, CTCAE criteria, and photodocumentation of the irradiated chest. The main objective of presented study is to evaluate the feasibility, safety, tolerance, and cosmetic effects of SBRT irradiation to the surgery bed in five fractions. In addition to standard clinical examination and evaluation of acute and late side effects, patients together with clinicians and nurses will independently complete a questionnaire on the impact of irradiation on the cosmetic effect. The technique of targeted external beam APBI should demonstrate better feasibility and less toxicity than the standard regimen in the adjuvant setting in treating early-stage breast cancer patients. Consequently, the presented study should increase the level of evidence for RT-indicated patients to the establishment of external APBI into daily clinical practice.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	APBI vs. WBI - toxicity	Comparison of acute and late toxicity of the APBI of the early stage breast cancer with accelerated irradiation regimen.	44 months
Primary	APBI vs. WBI - cosmetic effects	Comparison of cosmetic effects of the APBI of the early stage breast cancer with accelerated irradiation regimen. Cosmetic effects independently evaluated by patient, physician, and nurse scored using Harvard scale (4-point Likert scale). The scale contains 4 values - nearly identical as untreated (the best outcome), slightly different, clearly different, seriously distorted (the worst outcome)	44 months
Primary	APBI - feasibility	Evaluation of feasibility of the APBI regimen based on the proportion of patients who completed radiation in a total of 10 days and the proportion of patients who were irradiated exactly according to technical guidelines.	44 months
Primary	APBI vs. WBI - tolerance	Comparison of tolerance of the APBI of the early stage breast cancer with accelerated irradiation regimen. The toxicity was evaluated by CTCAE criteria (Common Terminology Criteria for Adverse Events). The outcome to define the tolerance a safety was CTCAE grade II or greater skin toxicity.	44 months
Primary	APBI vs. WBI - safety	Comparison of safety of the APBI of the early stage breast cancer with accelerated irradiation regimen. The toxicity was evaluated by CTCAE criteria (Common Terminology Criteria for Adverse Events). The outcome to define the tolerance a safety was CTCAE grade II or greater skin toxicity.	44 months
Secondary	Quality of life C30	Quality of Life assessment using the standardized European Organisation for Research and Treatment of Cancer (EORTC) questionnaire QLQ-C30. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.	44 months
Secondary	Quality of life BR45	Quality of Life assessment using the standardized European Organisation for Research and Treatment of Cancer (EORTC) questionnaire with special module for patients with breast cancer (Breast QLQ-BR45). All of the scales and single item measures range in score from 0 to 100. A high score for the functional scales and functional single items represents a high/healthy level of functioning, whereas a high score for the symptom scales and symptom item represents a high level of symptomatology or problems.	44 months
Secondary	Effectivity	Assessment of effectivity of the treatment method by evaluating subsequent endpoints such as LC (local control) and OS (overall survival). Overall survival (OS) is defined as the time from randomization to death from any cause. Local control (LC) is defined as the time from randomization to the first local recurrence.	44 months
