Anatomic Stage I Breast Cancer AJCC v8

Reading the Anatomic Stage I Breast Cancer AJCC v8 Trial Landscape

ClinicalTrials.gov lists 64 US studies indexed under Anatomic Stage I Breast Cancer AJCC v8, and 35 of those are currently open to recruitment — roughly 55% of the total volume on the registry. That ratio is a useful proxy for activity level: a high share of recruiting studies often signals that research interest is current and that new enrollment opportunities are appearing, while a low share typically means the field is dominated by completed or follow-up work where most participant spots have already been filled. These counts reflect the public registry only and include studies at every stage of design, so they should be read as an index of research attention rather than as a measure of treatment availability.

The phase distribution for Anatomic Stage I Breast Cancer AJCC v8 shows 7 late-stage studies (Phase 3 and Phase 4 combined) alongside 19 earlier-phase entries (Phase 1 through Phase 2). Phase 1 and Phase 2 studies focus on early safety signals, dosing, and preliminary effect, while Phase 3 studies are typically the larger efficacy and safety trials submitted toward regulatory review, and Phase 4 studies follow approved interventions in real-world use. A condition weighted toward later phases often reflects a mature research pipeline with several interventions already close to or past approval, whereas a heavier early-phase tilt suggests the field is still exploring new mechanisms and candidate approaches.

Top sponsor activity for Anatomic Stage I Breast Cancer AJCC v8 is led by M.D. Anderson Cancer Center with 12 indexed trials, alongside 9 other organizations in the top contributor list. The list on this page surfaces up to 64 of the most relevant recent and active entries, ordered with recruiting studies first so practical options are visible. All figures are derived from the public ClinicalTrials.gov dataset maintained by the National Library of Medicine and are reproduced here for reference. Inclusion of a trial, sponsor, or intervention on this page is neither an endorsement nor a recommendation — eligibility, protocol changes, and site-level status can shift frequently, so always verify current details on ClinicalTrials.gov and consult a qualified healthcare provider before acting on anything you see here.
