Association between Family History of Cancer and Lung Cancer Risk among Japanese Men and Women.

Association between Family History of Cancer and Lung Cancer Risk among Japanese Men and Women. Tohoku J Exp Med. 2019;247(2):99-110 Authors: Yoshida K, Takizawa Y, Nishino Y, Takahashi S, Kanemura S, Omori J, Kurosawa H, Maemondo M, Minami Y Abstract Although cigarette smoking is a major risk factor for lung cancer, genetic susceptibility may also affect lung cancer risk. To explore the role of genetic risk, this case-control study investigated the association between family history of cancer at several sites and lung cancer risk. A total of 1,733 lung cancer cases and 6,643 controls were selected from patients aged 30 years and over admitted to a single hospital in Japan between 1997 and 2009. Information on family history of cancer was collected using a self-administered questionnaire and odds ratios (ORs) were estimated by unconditional logistic regression. Family history of lung cancer in first-degree relatives was associated with an increased risk of lung cancer among both sexes. According to histology and type of relatives, a parental history of lung cancer was significantly associated with an increased risk of female adenocarcinoma (OR = 1.72). Stratification by smoking status revealed that this significant positive association in women was limited to ever-smokers (OR = 4.13). In men, a history of lung cancer in siblings was significantly associated with an increased risk of small cell carcinoma (OR = 2.28) and adenocarcinoma...
