Transthoracic aspiration biopsy. Cytological classification of aspirated malignant tumour cells.
On correlating our cytological classification of aspirated malignant tumour cells from intrathoracic lesions with the histological classification of the same lesions, agreement was found in 75 per cent. The cytological criteria used for the classification of the  differentiated types of tumour cells were convenient. It is proposed to utilize the cytological classification in the planning of an individualized tumour therapy in cases not accessible to pretreatment bioptic histological classification.
