Evaluation of the preoperative stage and operative findings in patients with non-small cell lung cancer.
Lung cancer is responsible for 40% mortalities from malignant diseases in man and exhibits an extremely infiltrating way of growing. It does not respect the lobes' or the organs' borders and spreads by blood system, lymph system and per continuitatem. According to its biological characteristics and response to treatments it may be divided in to small cell lung cancer (SCLC) and non small cell lung cancer (NSCLC), which also includes other histological types. Lung cancer treatment includes surgical treatment, chemotherapy, radiotherapy, the combination of the former three as well as symptomatic treatment. In this study, we analyzed 125 patients with lung cancer, that were hospitalized at the Clinic for Thoracic Surgery in KCU Sarajevo. The difference according to gender is statistically significant because we had 111 (88,8%) male patients in comparison with 14 (11,2%) female patients. The average age of male patients was 60,3 years while female patients were 61,9 years old on average. Thus, the difference in average age is not statistically significant. In diagnostic procedures: chest radiography was the most significant in peripheral lesions (60, 8%). CT of the thoracic organs has a statistical significance because the tumor changes were confirmed in 123 patients (98,4%). In bronchoscopy, we had 120 patients (96,0%). The number of patients with preformed lobectomy (63) is statistically significantly greater in the observed group (125) then the number of patients with other operative procedures preformed. From the postoperative complications we had exitus letalis 2 (1,6%), wound infection 19 (15,2%), and 104 without complications (83,2%). The results of testing the significance of differences according to the cancer types in non small cell lung cancer were planocellular, adenocarcinoma, and macrocellular. Comparing the preoperative staging and operative findings through stages we obtained to the following results: in stage ST0 the deviation was 16,7%, STIA the deviation was 40,1%, STIB the deviation was 16,1%, STIIA the deviation was 11,1%, STIIB the deviation was 12,5%, STIIIA the deviation was 33,33%, STIIIB the deviation was 33, 3%. From the overall number of patients, who were in preoperatively graded stage STIA, operative findings confirmed STIA, which makes the most important statistically significant difference. In 36 patients or 28,8% the status was changed in operative finding. In 89 patients preoperative status or 72,2% remained unchanged following the operation.
