Staging the axilla with selective sentinel node biopsy in patients with previous excision of non-palpable and palpable breast cancer.
To present our experience in the therapeutic approach of the sentinel node biopsy (SNB) in patients with previous excision of the breast cancer, divided in non-palpable and palpable lesions, in comparison with time treatment and stagement of breast cancer. ⋯ The detection of the SLN is also feasible in patients with previous surgery of breast cancer. Because SLN metastasis rates are significantly smaller in non-palpable lesions, the effort in screening programs for early detection of breast cancer and also in improving histopathological confirmation of malignancy with ultrasound or stereotactic guided core biopsies must continue.

Comparative StudyThe use of 18F-FDG PET/CT in colorectal liver metastases--comparison with CT and liver MRI.
We compared 18-fluoro-2-deoxyglucose ((18)F-FDG) positron emission tomography-CT (PETCT) with contrast-enhanced whole-body CT (ceCT) in identifying extrahepatic disease and with manganese dipyridoxyl diphosphate (Mn-DPDP) liver MRI for liver metastases in patients with colorectal liver metastases being considered for surgery. ⋯ PETCT has incremental benefit over conventional ceCT in identifying extrahepatic disease in metastatic colorectal cancer. PETCT has high sensitivity and specificity for the presence of liver metastases and should be included early in initial pre-surgical evaluation and could potentially guide the use of Mn-DPDP MRI. However, Mn-DPDP MRI is superior for small liver metastases and remains a prerequisite for surgical planning in patients with confined liver metastases.
