Condition: Breast Cancer Metastatic · Breast Carcinoma · Sponsor: Istanbul Training and Research Hospital
Invasive ductal carcinoma is the most common type of invasive breast cancer. In cases where axillary lymph node metastases are diagnosed through screening, they can be found in up to 25% of cases, and in symptomatic cases, up to 60% of cases. The clinical detection accuracy of axillary lymph node metastases is only 33%. Accurate staging of lymph nodes in breast cancer patients is crucial for both prognosis and treatment. Ultrasonography is much more sensitive than physical examination alone for determining axillary lymph node involvement in breast cancer staging. Fine needle aspiration biopsy or core biopsy is diagnostic in lymph nodes that cannot be clarified solely by ultrasonography or are suspicious. Although biopsy sampling yields high diagnostic rates, it requires an experienced pathologist and sometimes takes weeks to yield results. Therefore, there is a need for faster and less costly diagnostic methods for diagnosing axillary metastases. Among thyroid cancers, papillary thyroid carcinomas, a malignancy in which the lymph node washout method is used to determine lymph node metastasis, are the most common. In papillary thyroid cancer patients, washout sampling of neck lymph nodes by fine needle aspiration, searching for thyroglobulin, a protein normally found in thyroid tissue, is considered one of the most valid methods for detecting lymph node metastasis in this cancer. In recent years, immune checkpoint molecules associated with cancer have been widely used as bioma…
