  • This study was conducted to evaluate the role of SLN biopsy using NIR-fluorescence in colon cancer patients with respect to detection rate, upstaging rate, frequency of aberrant lymph node drainage, accuracy, and sensitivity of the SLN biopsy procedure. (turkjsurg.com)
  • For high-risk melanoma, adjuvant therapy aims at eradicating melanoma micrometastases in those patients that carry an unacceptable risk of mortality from melanoma recurrence. (amegroups.org)
  • Forty-eight patients of clinically staged T1-T3 node negative colon cancer underwent laparoscopic/open resection. (turkjsurg.com)
  • One of the reasons for recurrence in pathologically node-negative patients could be missed micrometastasis and occult tumor cells on routine histopathological examination or inadequate lymph node harvesting leading to understaging ( 4 ). (turkjsurg.com)
  • It has eliminated unnecessary axillary lymph node dissection in more than half of the early breast cancers. (elsevierpure.com)
  • However, one of the unresolved issues in sentinel node biopsy is how to manage axilla surgery for sentinel node-positive patients and clinically node-negative patients.To evaluate the outcome of no axillary lymph node dissection in sentinel node-positive breast cancer, a prospective cohort study registering early breast cancer patients with positive sentinel nodes has been conducted (UMIN 000011782). (elsevierpure.com)
  • Patients treated with sentinel node biopsy followed by axillary lymph node dissection are also registered simultaneously to compare the prognosis. (elsevierpure.com)
  • Background: The prognostic significance of sentinel lymph node (SLN) micrometastases and the need for axillary lymph node dissection (ALND) on patients with micrometastases in SLNs remain controversial. (elsevierpure.com)
  • There are many reports on the frequency of non-sentinel lymph node involvement when isolated tumor cells are found in the sentinel node, but results and recommendations for the use of an axillary lymph node dissection differ among studies. (johnshopkins.edu)
  • This systematic review was conducted to give an overview of this issue and to provide recommendations for the use of an axillary lymph node dissection in these patients. (johnshopkins.edu)
  • We searched Medline, Embase, and Cochrane databases from January 1, 2002, through November 27, 2007, for articles on patients with invasive breast cancer who had isolated tumor cells in the sentinel lymph node (according to the sixth edition of the Cancer Staging Manual of the American Joint Committee on Cancer) and who also underwent axillary lymph node dissection. (johnshopkins.edu)
  • This pooled risk estimate was marginally higher than the risk of a false-negative sentinel lymph node biopsy examination (ie, 7%-8%) but marginally lower than the risk of non-sentinel lymph node metastases in patients with micrometastases (ie, approximately 20%) who are currently eligible for an axillary lymph node dissection. (johnshopkins.edu)
  • Because 36 (64%) of the 56 patients with isolated tumor cells in their sentinel lymph node also had non-sentinel lymph node macrometastases, those patients with isolated tumor cells in the sentinel lymph node without other indications for adjuvant systemic therapy might be candidates for axillary lymph node dissection.
