First experience with Sirius Pintuition ® - A novel magnetic localization system for breast cancer surgery

Surgical Marker Navigation System in Breast Conserving Surgery and Excision of Non-palpable Lesions: First Spanish Single-Center Experience

“…In our study, all the markers that were implanted could be successfully removed, which is consistent with current literature [8][9][10][11]. If we compare the retrieval rate of the seed within the specimen, we report a slightly lower rate (88.1%) than the reported on the literature.…”

“…In our series, most markers were placed under ultrasonographic guidance (82.1%) and were placed less than 5 mm from the lesion (84.5%). Clement et al also report a majority of placement guided by ultrasound (98%) and an accuracy of placement (< 5 mm) of 93% [9], which is slightly higher than our results. This might be due to the higher rate of ultrasound guidance for the placement.…”

“…Also, McCamley et al reported on a multicentric cohort of non-palpable breast lesions and targeted axillary nodes, that in 96% of cases the seed was located within the main specimen [18]. When we compare our results to Sirius Pintuition® technology, Bessems et al reported that the seed was retrieved within the specimen in 94% of the cases [10], as well as in the cohort by Clement et al [9]. We hypothesize that the higher rate of accidental dislocation during surgery is due to our initial scarce experience with the technology and the use of metal instruments in contrast to the rest of the literature published.…”

“…In fact, to our knowledge this is one of the largest cohorts published in the literature. The evidence published regarding the effectiveness of the SMN Sirius Pintuition® is scarce, with only two studies published in specialized journals [3,8] and four conference papers [9][10][11][12]. There is evidence, though, published on the literature about the use of other non-wire, probe-guided magnetically guided localization technology [13][14][15][16][17].…”

Resection Ratios and Tumor Eccentricity in Breast-Conserving Surgery Specimens for Surgical Accuracy Assessment

“…The value of this outcome measure becomes even more apparent in light of the increasing number of technologies that are currently being investigated for the purpose of breast tumor localization. These techniques include magnetic and paramagnetic localization (Magseed [28][29][30][31], Sirius Pintuition [32,33], MOLLI [34], TAKUMI [35]), radiofrequency reflector-based localization (SAVI SCOUT [36][37][38]), radiofrequency identification tags (LO-Calizer [39][40][41]), EnVisio [42]), and stereotactic marking using a carbon suspension [43][44][45]. Due to the lack of solid evidence with regard to clinical effectiveness, none of these investigated techniques have widespread adoption [46].…”
