Abstract

ABSTRACT Introduction After coronary heart disease and accidents, cancer is the third main cause of death and gastrointestinal cancers are comprised nearly half of deaths arising from cancer in Iran. Therefore this study was designed to explain frequency of gastrointestinal cancers among patients who referred to Shahid Rajai radiotherapy Center during 10 years. Methods Study was a retrospective research. Data were obtained by the review of patients' documents with gastrointestinal cancers during 2000-2009. Data included demographic variables and type of cancers. This center is located in Mazandaran province in the north of Iran which is the only radiotherapy center in this area. Data were analyzed by SPSS 19. Results Among 2086 patients (25.1% of all patients), 60.8% were male. Nearly half of them (47.9%) were elderly persons (above 65 years old) followed by, 39.3% middle aged (45-64) and 12.6% young (15-44). Mean age of men (62.1±14) was significantly higher than women (60.44 ±14) (P=0.003). Most common cancers among males were esophagus (20.4%), stomach (20.1%) and colorectal (16.6%) and females were esophagus (16.3%), colorectal (12.3%) and stomach (8.4%). Patients with esophagus cancer were older than others (67.2±14) (P=0.001). Frequency trend of stomach cancer during 10 years went up from 13 to 84 (in 2000 to 2009) (P=0.001). Conclusion Gastrointestinal cancers were the most common cancer among elderly persons. This study also found the same results. Esophagus was in the first place. Findings indicated that growth trend of stomach cancer was more than others which can be caused by geographic factors, genetics or changing the dietary habits.
