Key findings

What ClinicalTrials.gov does not surface for Breast Ductal Carcinoma In Situ on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. Breast Ductal Carcinoma In Situ is recruiting above its size-band peers.

    10 of 16 indexed trials (62.5%) are open to enrollment, against a 46.5% average across 28,061 conditions with fewer than 20 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. One sponsor concentrates Breast Ductal Carcinoma In Situ research.

    National Cancer Institute (NCI) accounts for 5 of 16 trials (31.3%). 9 distinct sponsors appear on at least one study for this condition label.

  3. Typical Breast Ductal Carcinoma In Situ enrolment sits around 113 participants.

    Median target enrolment is 113 among the 16 trials that report a genuine target (sentinel values excluded). 8 of those (50%) plan for fewer than 100 participants.

  4. Breast Ductal Carcinoma In Situ research is mostly interventional.

    15 interventional and 1 observational studies make up this index (93.8% interventional). Study type is sponsor-reported on ClinicalTrials.gov.

Why a small condition index still matters

Thin indexes still surface the registry rows that exist for this label. Counts stay small when ClinicalTrials.gov lists few studies under the condition string, not because this page omits rows. Verify any enrollment decision on ClinicalTrials.gov and with a clinician.
