New Pathfinder Approach With Radioactive Tracer Reduces Surgical Trauma.(Brief Article)
2001 NOV 15 - (NewsRx.com & NewsRx.net) -- A revolutionary technique to treat breast cancer could safeguard patients from painful and disabling side effects of surgery, Professor Umberto Veronesi, scientific director of the European Institute of Oncology reports.
Traditional breast surgery involves removing lymph glands in the armpit to determine if the cancer has spread and if further treatment is necessary. This can stop the lymph fluid from draining properly, resulting in persistent lymphoedema, which can lead to grossly swollen and painful arms and loss of mobility in the affected limbs. Between 10% and 20% of breast cancer patients are affected to some degree by lymphoedema after breast surgery and radiotherapy.
The new technique is designed to restrict lymph gland or node removal to cases in which the cancer has actually drained from the breast to the sentinel node, the first node into which breast cancer spreads - if it spreads at all. Veronesi, who is based in Milan, outlined the development at the ECCO 11 - the European Cancer Conference in Lisbon, Portugal.
A radioactive tracer is injected close to the tumor and carried by the lymphatic system into the sentinel node. This enables the surgical team to locate the node's position. A biopsy then establishes if the cancer has spread into the node - and if further surgery is necessary.
A study of 500 patients has shown that the new technique is as effective as routine dissection, which removes all lymph nodes in the axilla, most of which are totally healthy in women with early cancer. Veronesi told the conference: "The early ...
