Seven-day treatment with FMOX was effective against acute pneumonia caused by Staphylococcus aureus in a patient with lung cancer. Nine-day treatment with FMOX was effective against pulmonary suppuration caused by Streptococcus pneumoniae in a patient with lung cancer. Six-day and 7-day treatment with FMOX were excellently or moderately effective against suspected obstructive pneumonia in 2 patients with lung cancer. Five-day and 6-day treatment with FMOX were ineffective against fever of unknown origins in 2 patients with lung cancer. Overall, FMOX was effective in 4 of the 7 patients evaluated.
