Case-control study of gastric cancer screening in Venezuela.
A screening programme for early gastric cancer was introduced in the state of Tachira, Venezuela, in 1980.
Screening was performed by photofluorography, using two mobile units.
The efficacy of this programme in reducing mortality from stomach cancer was evaluated by means of a case-control study.
Cases were 241 individuals who died from stomach cancer in the period 1985-89.
Ten live controls per case were drawn from the electoral rolls, matched by sex, age and residence.
Exposure to the screening examination of cases and controls was assessed through individual linkage with the programme's centralised database.
