PURPOSE: There are differences between lung cancer alone and multiple primary malignancies associated with lung cancer (MPMLC) in terms of clinical characteristics. However, the importance of these differences has not yet been clarified. METHODS: Univariate and multivariate analyses were performed on 123 patients with MPMLC and 815 patients with lung cancer alone who underwent operative procedures for lung cancer from August 1982 to March 2004. RESULTS: Age, number of family with a family history of other malignancies except for smoking-related cancers, and pathological early stage of lung cancer were significantly high in patients with MPMLC based on univariate analyses (P < 0.0001, P < 0.05, and P < 0.05, respectively). Age and family history of malignancy were thus found to be significant factors based on a multivariate analysis. CONCLUSIONS: MPMLC demonstrated a significant association with advanced age and stronger hereditary factors in comparison with lung cancer alone, indicating the need for different approaches to properly manage and follow up risk patients.
