Aim: Multiple cancer rates increase with an average increased lifespan. Therefore, many malignant patients are at high risk for a second primary malignancy. This study aims to evaluate lung cancer patients with a previous malignancy.
Materials and Methods:Forty-five patients who underwent resection for a second primary lung cancer in our department between January 2007 and June 2013 were reviewed retrospectively.
Results:The patients included 37 (82.2%) males and eight (17.8%) females. When the patients were evaluated for the first primary malignancy, the distribution of the malignancies according to the systems was 14 (31.1%) urogenital malignancies, ten (22.2%) respiratory, six (13.3%) hematological, six (13.3%) endocrine, five (11.1%) malignancies, and four (8.9%) integumentary malignancies. The comparison of the site of primary malignancy and survival data showed that the rates of long-term survival were shorter in patients with gastrointestinal system malignancies and the difference was statistically significant (p=0.028). The long-term survival of patients who received chemotherapy after the resection of the first primary lung cancer was significantly shorter (p=0.016).
Conclusion:The follow-up of patients should be done more carefully by the consideration of the positive effects of early diagnosis on cancer prognosis and keeping in mind the risk of primary lung cancer development in a patient with other system malignancy. We especially recommend caution in administering chemotherapy to patients with double primary tumors after a lung cancer operation.
