Abstract

The effective screening, prognosis and survival rate of a patient with bronchogenic carcinomas such as adeno, squamous and carcinoid tumors, depends mainly upon the tumor type and the stage at the time of diagnosis. In spite of significant advancement in operative techniques, intensive-care medicine, oncology and pulmonary medicine in the last thirty years, the prognosis of bronchogenic carcinomas has remained virtually unchanged. So an early diagnosis of these tumors are important for treatment modality. However, in most of the cases the surgeon is unable to visually differentiate the tumor tissue from normal tissue and they seek pathologist support. However, a pathologist confirm the diagnosis or diseases status with the help of various immunohistochemical stains, which are time consuming and costly. Thus medical science needs a better, rapid and economic method to differentiate tumor tissues from normal tissues and a brief review of various approaches reveals that optimal methods must still be established.
