What is Gallbladder cancer: Incidence and survival in a high‐risk area of Chile about?

## Abstract We assessed population incidence rates 1998–2002 and 5‐year survival rates of 317 primary gallbladder cancer (GBC) entered in the population‐based cancer registry in Valdivia. We analyzed GBC incidence (Poisson regression) and GBC survival (Cox regression). Cases were identified by histology (69.4%), clinical work‐up (21.8%), or death certificate only (8.8%). Main symptoms were abdominal pain (82.8%), jaundice (53.6%) nausea (42.6%), and weight loss (38.2%); at diagnosis, 64% had Stage TNM IV. In the period, 4% of histopathological studies from presumptively benign cholecystectomies presented GBC. GBC cases were mainly females (76.0%), urban residents (70.3%), Hispanic (83.7%) of low schooling <4 years (64.0%). GBC standardized incidence rate per 100,000 (SIR) were all 17.5 (95%CI: 15.5–19.4), women 24.3, and men 8.6 (__p__ < 0.00001); Mapuche 25.0, Hispanic 16.2 (__p__ = 0.09). The highest SIRs were in Mapuche (269.2) and Hispanic women (199.6) with 8 years of schooling. Low schooling, female and urban residence were independent risk factors. By December 31, 2007, 6 (1.9%) cases were living, 280 (88.3%) died from GBC, 32 (10.1%) were lost of follow‐up. Kaplan Meier Gl
