ABSTRACT
OBJECTIVE:
Surgery on non-palpable breast lesions is becoming increasingly common and new techniques for preoperative lesion localization have appeared. Radio-guided occult lesion localization (ROLL) enables malignant or probably malignant non-palpable breast lesions to be located and biopsy of the sentinel node to be performed (SNOLL sentinel node and occult lesion localization). MATERIAL ANDMETHODS:
Included were 118 patients with malignant or probably malignant non-palpable breast lesions visible on ultrasonography in whom radio-guided lesion resection and sentinel node biopsy were indicated. 99mTechnetium-albumin colloid was injected into the periphery of the lesion under ultrasonographic guidance and all patients underwent preoperative scintigraphy.RESULTS:
From November 2001 to December 2004, 118 patients were included. All patients underwent conservative surgery, with the non-palpable lesion being located in all cases (100% lesion detection rate). The histological diagnoses were 81 invasive ductal carcinomas (68.64%), 7 infiltrating lobular carcinomas (5.93%), 5 mixed-type carcinomas (4.24%), 17 carcinomas in situ (14.40%), and 8 other invasive carcinomas (6.78%). The sentinel node was detected in 98.41%. DISCUSSION ANDCONCLUSIONS:
Radio-guided ROLL surgery on non-palpable lesions located under ultrasonographic guidance is a simple, fast technique that enables the lesion to be safely excised. Both ROLL and SNOLL can be carried out in the same intervention with a single ultrasound-guided injection of 99mTechnetium-albumin colloid with satisfactory results.
