Résumé
One hundred thirty-four lung cancer cases who were histologically proven in life and who had chest x-rays at time of initial diagnosis were entered into this retrospective study covering the period from January 1, 1979 to April 30, 1985The major histologic subtype of lung cancer in this study were similar to those cited by foreign literatures, namely epidermoid cell cancer (37). Adenocarcinoma (25), small cell cancer (20) and large cell cancer (5). By frequency and odds ratio, squamous cell and adenocarcinoma histologies presented with a peripheral radiographic location two times more than with a central location. On the other hand, small cell cancer histology was three times more associated with central radiogaphic presentation. Large cell cancer histology showed to be either centrally or peripherally located without preference. (author)
