Serum KL-6 levels in lung cancer patients with or without interstitial lung disease

JOURNAL OF CLINICAL LABORATORY ANALYSIS, Issue 5 2010

Abstract Background: It is not known whether lung cancer patients with interstitial lung disease (ILD) might have higher serum levels of KL-6, a high molecular weight glycoprotein classified as a polymorphic epithelial mucin. In addition, prognosis of these patients with elevated serum KL-6 levels might be poorer than that with normal KL-6 levels, but it has not been well clarified. Methods: Serum KL-6 levels in 273 lung cancer patients with or without ILD, and prognostic significance of elevated serum KL-6 levels in these patients were studied using uni- and multivariate analyses. Results: Serum KL-6 levels were elevated (>500,U/ml) in 73.5% of lung cancer patients with ILD and in 33.7% of those without ILD. Serum KL-6 levels in lung cancer patients with ILD were significantly higher than those without ILD. In lung cancer patients with ILD, elevated serum KL-6 has no prognostic significance, but in those without ILD, however, it was one of the unfavorable prognostic factors. Conclusions: Elevated serum KL-6 levels can be observed in lung cancer patients both with and without ILD. Having ILD has strong prognostic impact in patients with lung cancer. In those without ILD, however, elevated KL-6 levels may be related to poor prognosis. J. Clin. Lab. Anal. 24:295,299, 2010. 2010 Wiley-Liss, Inc. [source]


Peripheral T-cell lymphoma with diffuse pulmonary infiltration and an increase in serum KL-6 level

RESPIROLOGY, Issue 3 2007

Abstract: Peripheral T-cell lymphoma is a subtype of non-Hodgkin's lymphoma. A case of peripheral T-cell lymphoma showing diffuse pulmonary involvement together with a marked increase in the level of serum KL-6 is presented. CXR and CT revealed reticular and ground-glass opacities, which mimicked interstitial pneumonia. Immunopathological findings and an analysis of T-cell receptor gene rearrangements of the lung biopsy specimen led to a definite diagnosis of peripheral T-cell lymphoma. In addition, the extensive proliferation of type II pneumocytes, which stained strongly positive for anti-KL-6 antibody suggested that the pneumocytes were the source of serum KL-6. [source]
