Abstracts
jects who were evaluated for body temperature, leukocyte count, and erythrocyte sedimentation rate (BT, WBC, ESR). As for the body temperature it was recorded as: afebrile (af), subfebrile (SD, febrile (f) and highly febrile (hf), using the standard criteria. It was evidenced that 73.3% of the MA group patients were af, while 16.7 were sf, 6.6 f and 3.3% hf. In the TB group: 6.6% were af, 53.3% sf, 16.7% f and 24.4% hf. In the PN group: 13.4% were af, 30% sf, 33.3% f and 23.3% hf. Leukocytes: only 3.3% of the MA group patients had WBC below 4.0 x 109, WBC between 4.1 and 10.0 x 10’ was evidenced in 43.4% of the MA group, 60% of the TB group and 53.3% of the PN group. WBC level above 10 X lo9 was recorded in 53.3% of MA group patients, 40% of the TB group and 46.4% of the PN group. Erythrocyte sedimentation rate was below 20/h in 10% of the MA group patients, 13.4% of the TB group and 6.6% of the PN group. ESR between 21 and 50/h was evidenced in 26.6% of the MA group, 30% of the TB group and 20% of the PN group. ESR above 50/h was recorded in 63.3% of the MA group, 56.5% of the TB group and 73.4% of the PN group. Conclusion: The MA group patients were most frequently afebrile, with WBC increase above 10 X 109, and ESR above 50/h. Among the TB group sf and f conditions were most predominant, accompanied with normal or mildly elevated WBCs and ESR above 50/h. In the PN group, sf, f and v f were almost equally distributed, with WBC and ESR above 50/h. Multiple lung cancer Krejbich F, Zatloukal P, Petruielka L. Dept.

It is very important to differentiate multiple lung cancer from metastases of a single tumour. Patients with synchronous multiple Iung cancer have different prognosis and management needs different treatment strategy. In a 72-year old patient a diagnosis of a small cell carcinoma was put by a transthoracic fine-needle biopsy of the right lung. As a result of combined chemotherapy the tumour in the right lung completely regressed. However in the meantime a solitary pulmonary nodule grew in the contralateral lung. Considering the very slow growth of the left-sided nodule, which did not comply with SCLC biologic behaviour, a duplicite lung cancer was suspected. Therefore, a left upper was performed. Histologically, a different (epidermoid) type of bronchial carcinoma was confirmed. The diagnosis of multiple lung cancer is usua!ly difficult but very important because distinction from lung metastases may result in patient’s profit.

The efficacy of annual screening programs is controversial so we conducted a trial of secondary mass screening for lung cancer using the helical CT scan. Subjects: We performed a helical CT scan examination on all participants who were
suspected of having lung cancer as a result of primary screening that used miniature frontal and lateral chest X-rays and sputum cytology studies. Method: Scan parameters were as follows: phase 1 (1995.7-1996.6) 120 kV, 200 mA, slice thickness 10 mm, table speed 10 mm/s.; phase 2 (1996.7-1997.6) 100 mA, other conditions remained the same as phase 1. Results: Fifteen cases of lung cancer were detected among 600 participants. As to staging, there were 10 cases in stage I. The proportion of stage I carcinomas to the total cases was significantly higher when utilizing the helical CT scan. Four cases were smaller than 2 cm in diameter. Twelve of the 15 cases were treated surgically. Conclusion: Our trial provided that lung cancer screening programs using helical CT scan revealed more positive cases and cases in earlier stages of the disease.

The incidence of radiographic presentation of infiltrative pulmonary shadows was studied in 30 patients diagnosed as having pulmonary malignomas (MA), specific process (TB) and pneumonic infiltrates (PN) treated during 1997 at the Institute, however only in cases where infiltrative shadows were not accompanied by pleural effusions. For better orientation, pulmonary fields were classified as upper left and right (I-J1and Ur), middle left and right (MI and Mr) and lower left and right (Ll and Lr), as well as to the left and right hilar part. In the MA group 66.4% of the shadows were localized in the right lung, 30% in the left one, while they were bilateral in 3.3%. In the TB group 36.6% of the shadows were on the right side, 20% on the left, while bilateral shadows were the most predominant affecting 43.4% of the cases. In the PN group the changes were also most predominant on the right side and were evidenced in 63.4% of the cases, while left side changes were recorded in 23.4% and bilateral in 13.4% cases. As for the level of the changes, TB was most predominant in Ur (30%) followed by MA (26.6%) and PN (10%). In Mr there were 6.6% of MA, no TB cases, and 13.4% of the PN group. In Lr there were 13.4% of MA, 6.6% of TB group and 40% of PN group. In the right hilus there were 20% of the MA group. In Lg there were 6.6% of MA, 3.3% of TB and 13.4% of PN patients. In La there were 16.7% of TB cases, while in Id there were 13.4% of the MA group. In the left hilus there were 13.4% of the MA group. Conclusion: In the MA group the lesions were mostly located in the right lung, i.e. in its apex and right hilus or basally. TB changes were most frequently bilateral, or located in the right apex, while PN infiltrates were most frequently located in the lower right and middle parts, followed by upper left part and somewhat less frequently in the upper right and lower left parts.
