Outcome Measures

Primary Outcomes (1)

  • recurrence

    Recurrence was defined as the appearance of a lesion within 2-3 cm of the original surgical area with corresponding clinical manifestations, such as nipple discharge and imaging support, which was later pathologically confirmed as IDP

    The cut-off date for follow-up was September 2024

Study Arms (2)

recurrent

Patients who relapsed after receiving ultrasound-guided vacuum-assisted rotary excision

Procedure: enlarged resection

non-recurrent

Patients who did not relapsed after receiving ultrasound-guided vacuum-assisted rotary excision

Interventions

patients underwent secondary enlarged resection within 1 month after the diagnosis of IDP combined with ADH,

Also known as: secondary enlarged resection
recurrent

Sampling MethodProbability Sample
Study Population

You may qualify if:

  • IDP was diagnosed pathologically after VAE treatment
  • the tumor was a solitary lesion with the margin \>1cm from the nipple and the longest diameter of the tumor \<3cm
  • it was not associated with other breast diseases

You may not qualify if:
