Immunohistochemical Application to the Pathologic Diagnosis of Lung Cancer

Lung cancer is the most common cause of death from neoplasms in Korea. Since the pathologic diagnosis is very important to determine the optimal treatment protocol of the patients, not only pathologists, but also oncologists, have an interest in the diagnosis of cancer. At the present time, immunohistochemical studies do more than play a supplementary role on the biopsied or excised specimens from cancer patients. Thus, I have reviewed the general principles and applications of immunohistochemistry on the histologic diagnosis of lung cancer. (J Lung Cancer 2008;7(1):19�� 21)
