[A study on gastric cancer risk factors--a case-control study based on medical records (1) Matched pair method].
To determine the gastric cancer risk factors, a case-control study was performed. Cases were the gastric cancer patients operated at NCC hospital from 1980 to 1982. Controls were the patients in Adult Disease Clinic. Main items of risk factors were cancer family inheritance tobacco smoking and alcohol drinking. Although in the case of cancer family and tobacco smoking either alone might produce gastric cancer, the syncarcinogenic type of combination of cancer family, tobacco smoking and alcohol drinking might act most definitely in gastric carcinogenesis.
