Verdye approval for Breast SLN\u00a0across Europe\u00a0including Austria, Belgium, Croatia, Czechia, Denmark, Finland, Greece, Hungary, Ireland, Italy, Netherlands, Poland, Portugal, Romania, Slovenia, Sweden and the UK. Verdye has previously been approved for the breast SLN indication in Spain.<\/strong><\/p>

The presence of lymphatic metastases<\/a> is an important prognostic factor for the survival of breast cancer patients and their identification has a bearing on further treatment.1<\/sup> Sentinel lymph node biopsy (SLNB) remains a cornerstone in the management of early breast cancer and is the current standard of care for clinically and radiologically node-negative patients.2<\/sup><\/p>

Importantly, SLNB enhances patient\u2019s quality of life without compromising diagnostic accuracy or prognostic information for node-negative patients.3<\/sup> Until recently, the gold standard for SLNB in patients with breast cancer is radio-guided surgery with radioisotope<\/a> technetium-99m (99mTc) which has a reported sentinel lymph node (SLN) detection rate of 86.4%.4<\/sup> Some clinicians combine 99mTc with blue dyes such as Methylene Blue dye<\/a>, increasing the detection rate to 96%-99.8%.4<\/sup> However, both 99mTc and blue dyes have many associated adverse effects.5,6<\/sup> In particular, Methylene Blue dye is associated with many devastating effects including soft tissue necrosis, (permanent) skin tattooing at the injection site, metabolic and haematologic side effects making it infrequently utilised for routine surgical care.7<\/sup> Further, Patent Blue and Isosulphan Blue are associated with increased rates of adverse reactions (0.7% – 1.1% of cases) in comparison to Methylene Blue.8,9<\/sup> Also, the use of 99mTc imposes a significant burden on patients and hospitals, including the logistical challenges associated with pre-operative administration, risk of exposure to ionising radiation for healthcare professionals, and adherence to regulatory requirements for handling and storage of radio-pharmaceuticals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
