Changing trends in gastrointestinal malignancy in Indonesia: The Jakarta experience

Research output: Contribution to journalArticlepeer-review


Aims: To identify changing trends in gastrointestinal cancer incidence in Indonesia according to age, gender, histopathology, and cancer location. Methods: We examined retrospectively the demography, cancer location, and pathological characteristics of 295 consecutive gastrointestinal cancer patients admitted to Cipto Mangunkusumo National General Hospital in 2002–2006. We compared these data with data from 343 gastrointestinal cancer patients admitted in 2007–2011. The data were analyzed by chi-square, analysis of variance, Kolmogorov–Smirnov, and Mann–Whitney U tests using SPSS 21.0. Results: The most prevalent gastrointestinal cancers in 2002–2006 and 2007–2011 were colorectal cancer (76.3% and 71.4%), followed by gastric cancer (15.6% and 14.9%), esophageal cancer (7.4% and 7.6%), and duodenal cancer (0.7% and 6.1%).There was an increase in esophageal adenocarcinoma prevalence from 36.4% to 69.2% (p = 0.023). The mean age at diagnosis of esophageal cancer decreased from 53.02 ± 13.12) to 50.43 ± 11.93) years (p = 0.031). The percentage of patients with gastric cancer aged 30–60 years increased from 60.9% to 82.4% (p = 0.018) and the percentage of patients aged > 60 years decreased from 34.8% to 13.7% (p = 0.015). In the histopathological analysis of gastric cancer, the prevalence of adenocarcinoma increased from 58.7% to 78.4% (p = 0.036), whereas the prevalence of signet ring cell carcinoma decreased from 21.7% to 5.9% (p = 0.022). The prevalence of gastric cancer lesions extending to >1 location increased from 2.2% to 27.5% (p = 0.001).The frequency of duodenal cancer among women increased non significantly from 0% to 52.4% (p = 0.261). The demography, histopathology, and location of colorectal cancers did not change between the two periods. Conclusions: Our study shows some changing trends in gastrointestinal malignancy in Indonesia in terms of demography, histopathology, and the location of cancers from 2002–2006 to 2007–2011.
