We have read the article by Nysom et al. [1] entitled, ''Risk Factors for Reduced Pulmonary Function After Malignant Lymphoma in Childhood.'' It would seem that somehow Dr. Nysom et al. have misinterpreted the results reported by us [2] in that they claim that we ''found normal or better than normal lung function'' in our patients, and later that ''one study (ours) even found most lung function parameters at or above predicted,'' concluding that such a study is hard to believe.''
It is important to recognize that we state in our report that ''all PFT parameters were within normal limits for the whole study group'' and that ''only FEV 1 values were lower for the patients who received mantle irradiation.'' Moreover, we stated that ''more severe changes may be observed in a longer follow-up . . . or with other study techniques.''
We do not understand how this misunderstanding could have occurred, because it is obvious that no patient who has received chemotherapy could be expected to have better function than normal in any organs.
We therefore think it is important to bring to the at-tention of your readers the facts as we stated them, and not as they were attributed to us by Nysom et al. [1].
