چکیده
STUDY OBJECTIVES To evaluate lung function in patients cured from childhood acute lymphoblastic leukemia (ALL) with chemotherapy alone or plus bone marrow transplantation (BMT). Pulmonary toxicity is a well-recognized side effect of many ALL treatments. DESIGN Cross-sectional study conducted at least 3 years after cessation of therapy. SETTING Outpatient pneumology department of the University Hospital. PATIENTS Forty-four subjects (age range at observation, 6 to 23 years): 21 treated only with intensive Berlin-Frankfurt-Munster (BFM)-type chemotherapy for newly diagnosed ALL (group A), and 23 treated with chemotherapy plus BMT (group B). MEASUREMENTS A detailed history of smoking habit, respiratory symptoms, and diseases was recorded directly from the patients with the aid of their parents. A complete physical examination and lung function testing (lung volumes and diffusion capacity for carbon monoxide [DLCO]) were performed in all subjects. RESULTS No patient reported acute or chronic respiratory symptoms or diseases. In group A patients, lung function was in the normal range, except for three subjects in whom there was an isolated impairment of DLCO. In group B patients, lung function was markedly impaired, with more than half the patients having an abnormal DLCO. A statistically significant difference was found between the two groups for FVC (p = 0.022) and DLCO (p = 0.004). CONCLUSIONS Intensive, BFM-type frontline chemotherapy is not associated with late pulmonary dysfunction; however, retreatment including BMT can frequently injure the lung. Thus, in patients who undergo BMT and whose life expectancy is long, careful monitoring of lung function and counseling about avoiding additional lung risk factors is recommended.

Face Bones Involvement and Relapse in a Case of Childhood Acute Leukemia
Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...
