Abstract

TAKEZAKI and colleagues, Division of Epidemiology and Prevention, Aichi Cancer Center Research Institute, 1-1 Kanokoden, Chikusa-ku, 464-8681, Nagoya, Japan, investigated dietary factors as modifiers of risk for lung cancer in Japanese patients.

Background

Methodology

This hospital-based case control study recruited 367 male and 240 female patients with adenocarcinomas ; 381 males and 57 females with squamous cell or small cell carcinomas ; and 2964 male and 1189 female cancer-free outpatients matched with the cancer cases for sex and age. Odds ratios (ORs) and their 95% CIs for lung cancer were calculated with adjustment for potential confounding factors using an unconditional logistic model.

Results

Males and females who consumed cooked/raw fish but not dried/salted fish displayed decreased ORs (males: 0.51; females: 0.48) for adenocarcinomas at the highest quartile frequency compared with the lowest. In females, soybean curd consumption was associated with a decreased OR for adenocarcinoma . In males, frequent consumption of raw and green vegetables, fruit and milk was associated with decreased ORs for squamous cell and small cell carcinomas ; whereas consumption of carrot, pumpkin, egg and coffee was associated with increased ORs.
