Abstract

The last 100 years have seen the incidence of lung cancer transformed from it being an almost unknown disease to it far outstripping all other forms of cancer as a cause of death in many countries. In men it is responsible for about 40% of cancer deaths and in women it now rivals breast cancer as the major cause of cancer mortality. Many developing countries have a relatively low incidence of lung cancer but are beginning to see the rises already experienced elsewhere as the inhabitants take to smoking in increasing numbers. Lung carcinoma is largely a disease of the elderly and this tumor is very rare in children but occasional cases are encountered. It carries a very poor prognosis as spread of the tumor often results in it being inoperable at presentation while many patients with lung carcinoma have coexistent chronic obstructive lung disease that renders them unfit for surgery. Overall 5 year survival rates vary from 6-20%. Lung carcinomas fulfill many of the following criteria for successful screening programme : the condition is common ,the population at risk is well known and premalignant changes can be detected cheaply(eg,sputum cytology).Unfortunately the premalignant changes cannot be easily eradicated as there is no bronchopulmonary equivalent of a uterine cone biopsy. Nor does screening for early invasive growths by a combination of sputum cytology and radiography appear to reduce mortality. Transthoracic biopsy is a safe and effective procedure in the evaluation of benign lesions, undetermined pulmonary lesions and an important tool in those patients with a peripheral mass inaccessible by bronchoscopy. The methods that are commonly used are for obtaining materials for pathological diagnosis are: 1) Core needle biopsy by radiological intervention 2) Transbronchial biopsy 3) Transthoracic needle aspiration Our study is based on histomorphological profile of lung tumors on CT/USG guided core needle biopsies
