This 2014 study investigated the effects of core needle biopsy (CNB) on the dissemination of epithelial cellular material (ECM) into the bloodstream in patients with prostate cancer. Blood samples from 23 prostate cancer patients and 15 controls were analyzed before and after CNB. The results demonstrated a significant increase in
This 2004 study examined whether the method of preoperative biopsy influences the incidence of sentinel lymph node (SN) metastases in invasive breast cancer. Analyzing 676 cases, patients were grouped based on biopsy type: fine-needle aspiration (FNA), large-gauge needle core, or excisional biopsy. Results indicated that FNA and core biopsies were
This retrospective cohort study analyzed long-term outcomes in breast cancer patients diagnosed using fine-needle aspiration biopsy (FNAB) in the 1970s versus core-needle biopsy (CNB) in the 1990s. Researchers matched patients on age, tumor size, DNA ploidy, mammography screening status, and treatment protocols. The findings indicated a significantly higher incidence of
