Ki-67 Labeling Index in Pulmonary Carcinod Tumors Comparison Between Small Biopsy and Resection Using Tumor Tracing and Hot Spot Methods

摘要

Context.-Pulmonary carcinoids are classified as typical or atypical by assessing necrosis and mitoses, which usually cannot be adequately assessed on small biopsies. Ki-67 is not currently used to grade pulmonary carcinoids, but it may be helpful to determine preliminary grade in biopsies. However, the rate at which Ki-67 could underestimate or overestimate grade on small biopsies has not been well studied.
