Sentinel lymph node biopsy is associated with reduced arm morbidity and better quality of life than standard axillary treatment and should be the treatment of choice for patients who have early-stage breast cancer with clinically negative nodes.
These data demonstrate that all three transcription factors have inappropriate expression in breast cancer and that this may play a part in the progression of human breast tumors.
SLNB can accurately determine whether axillary metastases are present in patients with early stage breast cancer with clinically negative axillary nodes. Both success and accuracy of SLNB are optimised by the combined use of blue dye and isotope. SLNB success decreases with increasing body mass, tumor location other than the upper outer quadrant and non-visualisation of hot nodes on the pre-operative lymphoscintiscan. This study demonstrates reduction in the predictive value of a negative SLNB in grade 3 tumors.
PurposeWire localization has several disadvantages, notably wire migration and difficulty scheduling the procedure close to surgery. Radioactive seed localization overcomes these disadvantages, but implementation is limited due to radiation safety requirements. Magnetic seeds potentially offer the logistical benefits and transcutaneous detection equivalence of a radioactive seed, with easier implementation. This study was designed to evaluate the feasibility and safety of using magnetic seeds for breast lesion localization.MethodsA two-centre open-label cohort study to assess the feasibility and safety of magnetic seed (Magseed) localization of breast lesions. Magseeds were placed under radiological guidance into women having total mastectomy surgery. The primary outcome measure was seed migration distance. Secondary outcome measures included accuracy of placement, ease of transcutaneous detection, seed integrity and safety.ResultsTwenty-nine Magseeds were placed into the breasts of 28 patients under ultrasound guidance. There was no migration of the seeds between placement and surgery. Twenty-seven seeds were placed directly in the target lesion with the other seeds being 2 and 3 mm away. All seeds were detectable transcutaneously in all breast sizes and at all depths. There were no complications or safety issues.ConclusionsMagnetic seeds are a feasible and safe method of breast lesion localization. They can be accurately placed, demonstrate no migration in this feasibility study and are detectable in all sizes and depths of breast tissue. Now that safety and feasibility have been demonstrated, further clinical studies are required to evaluate the seed’s effectiveness in wide local excision surgery.
The allergic potential of patent blue V dye compares favourably with isosulfan blue however both the surgeon and anaesthetist need to be alert to the risk of allergic reactions.
The indiscriminate use of SLNB in patients with DCIS seems excessive. Our study suggests that patients with a mass on clinical examination or mammogram have an increased risk of invasive disease at the time of definitive operative procedure and should undergo SLNB at the initial procedure. In addition, SLNB should be performed in patients undergoing mastectomy because mastectomy precludes SLNB if invasive disease is subsequently discovered.
Breast pain or mastalgia is the common symptom in the breast. The two most common concerns of patients presenting with mastalgia are: the fear that breast pain is a symptom of breast cancer and the presence of severe pain that affects a woman's quality of life. Breast pain requires thorough assessment and should be investigated in the same manner as any other breast symptom. We conducted a systematic review of treatment for breast pain. We searched various reviews, randomized controlled trial, and observational studies over Pubmed and Medline via internet. Searches were carried out on MEDLINE
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
