- Patients with any stage of small cell lung cancer were given low-dose interferon-alpha (IFN-alpha) from the first day of treatment as long as possible irrespective of changes in treatment dictated by disease progression. All patients received 6 cycles of the chemotherapy (CT): cisplatin 70 mg/m2 i.v. day 1 and etoposide 100 mg/m2 i.v. days 1, 2, 3 every 28 days. Seventy-eight patients were assigned to arm 1: CT alone, 75 patients to arm 2: CT + natural IFN-alpha (3 MU three times a week i.m.), and 66 patients to arm 3: CT + recombinant IFN alpha-2a (3 MU three times a week i.m.). There was no difference in median survival between the arms (10.2 months, 10.0 months, 10.1 months, respectively), p = 0.32. The 2-year survival rates were 15%, 3%, and 11%, respectively. Grade 3 and 4 leukopenia occurred more frequently in the IFN arms than in the CT alone arm and resulted in dose reductions. Antibodies occasionally developed to recombinant IFN. We conclude that IFN-alpha can be administered concomitantly with chemotherapy but is probably better kept for maintenance therapy so that optimal full doses of induction CT can be given.

- BACKGROUND AND PURPOSE: We undertook this study to evaluate the frequency and risk factors of white matter hyperintensities seen on T2-weighted MR imaging. We examined cohorts of neurologically nondiseased elderly subjects participating in a general-community study, the Helsinki (Finland) Aging Brain Study. Cohorts of consecutive subjects aged 55, 60, 65, 70, 75, 80, and 85 years (n = 20, 18, 20, 18, 19, 18, and 15, respectively; total, n = 128) were divided into a young-old (age < 75 years, n = 76) group and an old-old (age > or = 75 years, n = 52) group. METHODS: Frequency of hyperintensities seen on T2-weighted axial and coronal MR images (0.02 T) was rated using a four-point scale in periventricular and centrum semiovale areas. RESULTS: The majority of the subjects showed only mild white matter hyperintensities, which were more frequent in the periventricular areas. Age was the most important factor to explain the presence of hyperintensities. A logistic regression analysis related periventricular hyperintensities in the entire group to central atrophy (odds ratio [OR], 4.7; 95% confidence interval [CI], 1.7 to 12.9) and silent infarcts (OR, 5.6; 95% CI, 1.0 to 19.8); among the young-old, hyperintensities related to diabetes (OR, 17.0; 95% CI, 1.9 to 154.2) and central atrophy (OR, 14.7; 95% CI, 3.5 to 61.8). Centrum semiovale hyperintensities related in the entire group to cardiac arrhythmia (OR, 4.0; 95% CI, 1.0 to 15.5), central atrophy (OR, 3.9; 95% CI, 1.2 to 12.4), and silent infarcts (OR, 3.6; 95% CI, 1.0 to 12.5). CONCLUSIONS: These mild white matter hyperintensities in the neurologically nondiseased elderly related especially to age and also to concomitant silent infarcts, atrophy, and some vascular risk factors. The known factors, however, explained only part of the variation. The young-old and old-old groups showed different associations. In contrast to former assumptions, the presence of white matter hyperintensities among the aged is likely to be linked to other as yet unidentified age-related factors.
