The results of PFT performed at least 1 year from diagnosis were available for 80 patients. Median time of follow up was 3.9 years (range 1.1–11.76 years). Median cumulative dose of bleomycin was 65 IU/m<sup>2</sup> (range 10–120). The most common diagnoses were Hodgkin lymphoma and germ cell tumor. At least one pulmonary function abnormality was present in 42 (52.5%) patients. When classified in groups, 22.5% patients had obstructive lung disease, 7.5% had restrictive lung disease, 28.8% had hyperinflation and 14% of patients had non‐uniform distribution of ventilation. Non‐Hispanic patients (OR 2.81) and children younger than 8 years (OR 4.14) had higher odds of having an abnormal PFT parameter. Very few patients had pulmonary symptoms.</p> </sec> <sec id="pbc25098-sec-0004" sec-type="section"> <title>Conclusions</title> <p>More than half the patients who received bleomycin had subclinical pulmonary dysfunction as evidenced by abnormalities in pulmonary function tests, although the incidence of clinical symptoms was low.
