Different Localization Techniques for Non-palpable Breast Lesions

Status Recruiting

Clinical Trial Summary

Breast conservative surgery (BCS) is nowadays the standard of care for patients affected by early breast lesions. Screening programmes led to an increase of non-palpable breast lesion detection rates. These patients are often eligible for BCS and an accurate preoperative localization technique for the detection of the lesion is required to guarantee a safe surgical excision. The primary goal of BCS is to obtain a complete resection of the tumor with disease-free surgical margins. The presence of tumor on surgical margins on postoperative histological examination of the specimen increases the risk of local recurrence and it requires a surgical re-excision. For all these reasons different techniques for localization of non-palpable breast lesions have been developed over time. Since '70s the wire guided localization (WGL) technique has represented the gold standard; however it has several limitations such as wire migration or fracture and patient referred discomfort related to wire placement. Over time, other techniques have been proposed, such as the radioguided occult lesion localization (ROLL), radioactive and magnetic seeds, carbon dye and ultrasound-guided preoperative localization. Currently there are several studies of comparison between the WGL and the more modern techniques. All of these data claim the effectiveness of the new "wire-free" methodics ensuring a safe surgical resection with tumor-free margins and, in some cases, a better aesthetic result. Studies of comparison between the modern techniques are limited. There is no scientific evidence of the superiority of a technique over the other. A multicentric Italian survey demonstrated that the most used localization techniques nowadays are the WGL, ROLL, the magnetic seed and the carbon dye. The aim of this retrospective study is to compare these techniques to assess their efficacy in the localization of non-palpable breast lesions.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
