Abstract

There is accumulating evidence of an increased risk of familial clustering of cancer in the first-degree relatives of lung cancer probands. However, no explanation has been proposed for these epidemiological data. We reviewed 379 female non-small-cell lung cancer (NSCLC) patients to obtain their family histories of malignancy. Among them, nine female NSCLC patients with three or more relatives diagnosed with malignancy and 28 control patients without a family history of malignancy were selected to be analysed for instability at six different microsatellite loci. We observed microsatellite instability (MSI) more frequently in the patients with three or more family histories of malignancy (six out of nine, 67%) than the control patients (5 out of 28, 18%). The incidence of MSI in the former was significantly higher than that in the control (P=0.011: Fisher's exact test). We detected no significant difference in clinicopathological characteristics between the cases with MSI and those without MSI, except for their family histories of cancer. Our results show that a significantly higher rate of MSI is associated with familial clustering of malignancy. MSI could be one of the underlying mechanisms for familial clustering of malignanc...Continue Reading
