Administration of a tumour-seeking compound labeled with a low-energy isotope and intraoperative screening with the gamma probe (radioguided surgery, RGS) could be useful in reoperations for advanced neuroblastoma when the normal anatomy is altered. A pilot study was performed to test the feasibility of this technique. Five patients underwent six relaparotomies for recurrent stage III or IV neu...
The 'regional nodal mapping', is a fundamental step to stage breast carcinoma. In addition to the axillary nodes status, the involvement of internal mammary nodes is an important prognostic factor. Six hundred and sixty-three patients with breast carcinoma, mainly in the inner quadrants, underwent a biopsy of internal mammary nodes. Positive internal mammary nodes were found in 68 out of 663 ca...
A patient with a history of a jejunal carcinoid and resection of liver metastases underwent CT, MRI and FDG-PET as well as somatostatin receptor scintigraphy using 111In-pentetreotide during follow-up. Octreoscan demonstrated one extrahepatic abdominal lesion with pathologic uptake, while the other imaging modalities failed to show a corresponding abnormality. For verification of this finding 1...
Discovery of osteitis may be delayed because of late appearance of X-ray signs in patients with diabetic foot. Scintigraphy with labelled leukocytes is able to detect flogosis but often misses bone involvement, due to inadequate resolution of Anger camera, the commonest detector used in nuclear medicine. Radioguided surgery and biopsy with high resolution scintigraphy (HRS) started to be studie...
Sentinel node mapping is becoming a routine procedure for staging of various malignancies, because it can determine lymph node status more precisely. Due to anatomical problems, localizing sentinel nodes in the head and neck region on the basis of conventional images can be difficult. New diagnostic tools can provide better visualization of sentinel nodes. In an attempt to keep up with possible...
Aims and background: Locoregional lymph node status is one of the most important prognostic factors determining the need for adjuvant chemotherapy in patients with breast cancer. Many authors have reported that micrometastases were not detected by routine sectioning of lymph nodes but were identified by multiple sectioning and additional staining. Among lymph node-negative patients 15-20% had a...
We read with interest the editorial by Chung discussing advantages of radio-guided occult lesion localisation (ROLL) over other commonly used pre-operative localisation techniques for breast tumours. While the results from our audited introduction of ROLL support the conclusion that ROLL is “a simple and effective solution for guiding the excision of impalpable breast lesions”, two important dr...
