title: [Significance of the bioclean room during the treatment of lung cancer].
abstract: The effectiveness of a vertical air flow room using HEPA filter (class 5000) was studied in relation to the prevention of infection during induction chemotherapy for primary lung cancer and metastatic pulmonary tumors. From November 1982 to July 1983, 12 patients (11 primary lung cancer: 9 small cell carcinoma, 2 non-small cell carcinoma and 1 metastatic pulmonary tumor) were treated in the bioclean room, while 14 patients (1 small cell carcinoma, 13 non-small cell carcinoma) were treated in conventional room during this period as control. Partial response was observed in 6 patients with small cell carcinoma treated in the bioclean room and 4 patients with non-small cell carcinoma treated in the conventional room. In patients treated in the bioclean room, the median day of stay in the room was 21 ranged 9 to 43. The leukocyte counts in the peripheral blood less than 1500/mm3 and 1000/mm3 were observed in 6 and 4 cases, respectively. Decrease in granulocyte counts less than 500/mm3 was observed in 6 cases. Only one patient with leukocyte count of 800 (granulocyte count 104) experienced fever higher than 38 C lasting 8 days. On the other hand, in 14 patients treated in the conventional room, leukocytopenia less than 1500/mm3 and 1000/mm3 was observed in 7 and 0 cases, respectively. Granulocytopenia less than 500/mm3 was observed in 8 cases, and 7 patients experienced fever higher than 38 C. Number of non-viable particles in the bioclean room ranged from 2.9 to 6.8 X 10(2)/ft3. Organisms isolated from the bioclean room and from the skin of patients were normal flora, and the numbers of colonies detected from the skin of patients decreased 1-2 weeks after the beginning of treatment in the bioclean room. The usefulness of a vertical air flow room during chemotherapy of lung cancer, especially of small cell carcinoma, was suggested.
