HER2-negative breast cancer patients with high relapse risk after standard neoadjuvant treatment, HER2-negative breast cancer
Conditions
Brief summary
iDFS is defined as time from randomization until first iDFS event: local invasive recurrence following mastectomy, local invasive recurrence in the ipsilateral breast following lumpectomy, regional recurrence, distant recurrence, contralateral invasive breast cancer, second non-breast primary cancer (excluding squamous or basal cell carcinoma of the skin), or death from any cause.
Detailed description
OS is defined as the time from randomization until death from any cause., DDFS is defined as the time from randomization until distant recurrence of disease, second primary invasive cancer (non-breast, excluding squamous or basal cell carcinoma of the skin), and death due to any cause., iBCFS is defined as the time from randomization until first iDFS event excluding any second non-breast primary cancer., LRRFI is defined as the time from randomization until any loco-regional (ipsilateral breast (invasive), chest wall, local/regional lymph nodes) recurrence of disease or any invasive contralateral breast cancer whichever occurs first. Distant recurrence, secondary malignancy and death are considered as competing risks and will be accounted for in the analysis., Frequency and severity of adverse events graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0., Dose-density, dose reductions, dose delays, treatment interruptions and treatment discontinuation rates., Patient reported breast cancer specific QoL as measured by FACT–B; functional assessment of cognitive function assessed by FACT-Cog; patient reported global QoL assessed by EQ-5D-5L.
