EVALUATION OF THE REGIONAL METASTATIC SPREADING OF THE NON-SMALL CELL LUNG CANCER COMPLICATED BY THE SECONDARY INFLAMMATORY PROCESS

Objectives. Estimation of the diagnostic value of the computer tomography and mediastinoscopy at complications of the non-small cell lung cancer course (NSCLC) with the secondary inflammatory process.
Methods. The retrospective analysis of the treatment results of 365 patients operated on with NSCLC was carried out. In 280 of them the course of cancer was without the signs of the infection; in 85 of them the secondary inflammatory changes of the lung tissue were revealed. On the ground of the patients inspection results before the operation and the data of the pathological-anatomical investigation of the operative material the diagnostic value of the CT and mediastinoscopy was estimated in the evaluation of the regional metastasis spreading of NSCLC.
Results. The presence of the secondary inflammatory process practically doesnt influence the CT sensitivity in the evaluation of N criterion; at the same time the specificity is significantly lower and it results in the reduction of the general diagnostic accuracy of CT informational content of mediastinoscopy doesnt depend on the presence of the secondary inflammation (accuracy 89,7% and 91,7% in the groups compared).
Conclusion. The secondary inflammation at NSCLC reduces the diagnostic value of CT in the evaluation of the metastasis lesion of the intrathoracic lymphatic nodes; though the accuracy of mediastinoscopy remains high.
