What this phase means
This study does not use the classic phase 1–4 drug ladder. It may be a device, a behavior program, a surgery timing study, or an early feasibility test.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Endoscopy-assisted breast-conserving surgery (SRRSHzb-EABCS), or Conventional open breast-conserving surgery (CBCS). The registry lists allocation as randomized. This multicenter, open-label, prospective, randomly assigned controlled study compares a novel endoscopy-assisted breast-conserving surgery technique (SRRSHzb-EABCS) with conventional open breast-conserving surgery (CBCS) in women with breast cancer who wish to preserve their breast.
They plan to enroll about 422 people at 22 sites. Taking part typically means a procedure as part of the study plus check-ins.
