Brief Summary

Calcification clusters are 30-40% of recalls in mammographic screening, but have a low positive predictive value (\~15%) for ductal cancer in situ (DCIS) or invasive cancer. These calcifications often need histological assessment with stereotaxic guided biopsy (Mammotome). With extended calcifications, choosing the best area to biopsy may be challenging. The main objective of this 1:1 randomized controlled clinical trial is to compare the accuracy of the CESM guide (study arm with biopsy under CESM guidance) with the traditional Mammotome (control arm with biopsy under stereotactic guidance) in conducting the biopsy in the area of greatest malignancy/grade of the lesion, using as gold-standard the histological exam of the operating piece. Women recalled with indication to perform stereotactic biopsy for clusters of suspicious calcifications on mammography (BIRADS R3 or R4 or R5) not mass-associated will be included. Anticipated sample size is 100 women per arm.

Outcome Measures

Primary Outcomes (1)

  • Distance in mm between the biopsy site and the area of greatest malignancy/grade in the operating piece.

    In patients sent to surgery, the main outcome will be determined on the operating piece by a single pathologist operating in blind, which will assess the type of lesion (B1-B5), invasiveness, grade, the extent of the lesion in mm, the percentage of invasive component, the distance in mm between the location of the biopsy and the area of greatest malignancy (DCIS G3 or invasive component). In patients not sent to surgery, the outcome will be determined by following the patients for a follow-up of at least 24 months, verifying if they have undergone surgery on that specific lesion during the follow-up (in particular if they have developed B5 lesions in situ or invasive in that location).

    Cross-sectional: the reference standard will be collected during surgery, usually 3 to 6 weeks after biopsy. In any case, it cannot be collected more than 6 months after biopsy.

Secondary Outcomes (7)

  • Proportion of patients needing contrast imaging

    Cross-sectional: the reference standard will be collected during surgery, usually 3 to 6 weeks after biopsy. In any case, it cannot be collected more than 6 months after biopsy.

  • Diagnosis upgrading

    Cross-sectional: the reference standard will be collected during surgery, usually 3 to 6 weeks after biopsy. In any case, it cannot be collected more than 6 months after biopsy.

  • Biopsy sensitivity

    The reference standard will be collected during surgery, usually 3 to 6 weeks after biopsy. Women not needing surgery (negative at biopsy) will be followed up for 24 months in orther to assess the presence of cancers.

  • Waiting time between biopsy and surgery

    The outcome measure is the time from biopsy to first surgical intervention, usually this time is in the range of 3 to 6 weeks.

  • Accuracy for lesion size

    Cross-sectional: the reference standard will be collected during surgery, usually 3 to 6 weeks after biopsy. In any case, it cannot be collected more than 6 months after biopsy.

Study Arms (2)

Contrast enhanced mammography guided biopsy

EXPERIMENTAL

Patients will be subjected to CESM; the two orthogonal mammographic projections, after intravenous administration of iodized contrast-enhancement (Omnipaque), will be performed. Surgical and medical treatments will be defined accordingly to the imaging and histological findings obtained with the experimental procedure.

Other: Contrast enhanced mammography guided biopsy (diagnostic procedure)

mammography guided biopsy

ACTIVE COMPARATOR

Patients will be subjected to stereotactic biopsy Mammotome as normal clinical practice. Surgical and medical treatments will be defined accordingly to the imaging and histological findings obtained with the standard procedure.

Other: Mammography guided biopsy (diagnostic procedure)

Interventions

With visible contrast-enhancement, stereotactic biopsy will be performed under CESM guidance. After administration of an additional dose of iodized contrast-enhancement (Omnipaque), the insertion of the biopsy needle and the biopsy sampling will be targeted on the area of greatest enhancement in the context of calcifications. In the absence of contrast-enhancement, stereotactic biopsy Mammotome will be performed, using X-ray guidance. The insertion of the biopsy needle and biopsy will be targeted on the most suspicious calcification cluster or area. At the end of the procedure, a metal clip marker will be placed in the biopsy site; the placement will be verified with dual orthogonal mammography projection (as regular clinical practice).

Contrast enhanced mammography guided biopsy

For all lesions, stereotactic biopsy Mammotome will be performed, using X-ray guidance. The insertion of the biopsy needle and biopsy will be targeted on the most suspicious calcification cluster or area. At the end of the procedure, a metal clip marker will be placed in the biopsy site; the placement will be verified with dual orthogonal mammography projection (as regular clinical practice).
