Latest Sentinel lymph node Stories
During the past two decades there has been a significant increase in the percentage of patients who have a high number of lymph nodes evaluated during colon cancer operations, but this improvement is not associated with an increase in the overall proportion of colon cancers that are node positive.
A new study shows removing lymph nodes because of the presence of microscopic cancer cells found in the sentinel node has no impact on survival among women with early-stage breast cancer.
A common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area.
A new study shows that removing lymph nodes due to the presence of occult, or microscopic, cancer cells found in the sentinel lymph node â€“ the one closest to the tumor -- has no impact on survival outcomes of women with early-stage breast cancer.
The sentinel node (SN) procedure in breast cancer is based on the premise that if the first node into which breast tissue drains is clean, the remaining lymph nodes in the armpit are likely not involved, with no need for removal.
The validation of a test, based on gene expression and predicting the tumours that will metastasize in lymph nodes of head & neck cancers.
A study released Tuesday by the Journal of the American Medical Association (JAMA) leaves researchers with evidence that early stage breast cancer patients who have a small amount of lymph node removed fare as well as those who get more extensive surgery.
Among patients with early-stage breast cancer that had spread to a nearby lymph node and who received treatment that included lumpectomy and radiation therapy, women who just had the sentinel lymph node removed (the first lymph node to which cancer is likely to spread from the primary tumor) did not have worse survival than women who had more extensive axillary lymph node dissection (surgery to remove lymph nodes found in the armpit).
Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a second breast cancer surgery.
Predicting breast cancer spread from a sentinel lymph node removed during surgery is a hit or miss affair, say researchers: there are still many false negatives, which means the node, when analyzed under a microscope, appears clean of cancer cells, but metastasis can still occur in the patient.
