title: Trends in oesophagus and Stomach cancer incidence in Bangalore, India.
abstract: BACKGROUND
  During recent decades, an increase in the incidence of certain oesophago-gastric cancer has been reported in some countries and in India. This study sought to analyze oesophageal and gastric cancer incidence trends in Bangalore by sex and morphology for the period 1982-2007.
  
  
  METHODS
  Oesophageal and gastric cancer cases were drawn from Bangalore population-based cancer registry locating in Kidwai memorial Institute of Oncology started in 1982 under national cancer Registry Programme funded by Indian Council of Medical Research. Time trends in sex- and age-standardized cancer incidence rates were analyzed by site and histology over the study period, using relative change.
  
  
  RESULTS
  Age-standardised oesophageal cancer incidence rates increased in males, in females failed to register a significant trend over the study period. Overall, gastric cancer decreased from 9.81 and 5.48 rates per 100 000 person-years in 1982-86 to 9.45 and 5.25 in 2002-07, among men and women, respectively. Where as oesophageal adenocarcinomas increased sharply in both sex, among men, oesophageal squamous cell cancer rates increased steadily from the mid-1982s onwards a bit decline was observed from 1997, the same trend observed in females. The gastric cancer decreased over the study period. There was a marked decrease in the incidence of oesophago-gastric cancer presenting with unknown and unspecified morphology reported.
