“…Although CRCs have generally been more common in the countries of North America, Oceania, and Europe, the incidence of CRC in Asian and South American countries has increased considerably during the past decade. In Chile, mortality from CRC has increased rapidly over the past 15 years, and the prevention of CRC has come to be recognized as an urgent issue that might be addressed through organized screening systems.…”

of 10,575 asymptomatic participants were enrolled in PRENEC. Participants with positive immunochemical fecal occult blood test (iFOBT) results or a family history of CRC underwent colonoscopy. The colonoscopy results from a similar, previous project in Chile (PREVICOLON) were compared with those from PRENEC. Furthermore, the initial colonoscopies of 1562 participants in PRENEC were analyzed according to whether the colonoscopists were from TMDU or Chile. RESULTS: The complete colonoscopy, adenoma detection, and cancer detection rates were 88.0%, 26.7%, and 1.1%, respectively, in PREVICOLON, while the corresponding values were 94.4%, 41.8%, and 6.0%, respectively, in PRENEC. In PRENEC, 107 cases of CRC were detected, amounting for 1.0% of all participants. Considering initial colonoscopies in PRENEC, the complete colonoscopy, adenoma detection, and cancer detection rates were 97.4%, 45.3%, and 9.3%, respectively, for physicians at TMDU and 93.3%, 41.5%, and 5.1%, respectively for Chilean physicians. The detection rates of intramucosal cancer were 7.3% and 3.7%, respectively, for TMDU and Chilean physicians. CONCLUSIONS: Quality indicators of colonoscopy substantially improved from PREVICOLON to PRENEC. The assessments made by Chilean physicians alone were improved in PRENEC, but remained better in the TMDU group. Moreover, physicians from TMDU detected more CRCs than Chilean physicians, especially at earlier stages. Cancer 2016;122:71-7.

INTRODUCTIONColorectal cancer (CRC) is the third most common cancer and the fourth most common cause of mortality in the world, accounting for approximately 694,000 deaths in 2012. 1 Although CRCs have generally been more common in the countries of North America, Oceania, and Europe, the incidence of CRC in Asian and South American countries has increased considerably during the past decade. In Chile, mortality from CRC has increased rapidly over the past 15 years, 2 and the prevention of CRC has come to be recognized as an urgent issue that might be addressed through organized screening systems.Some studies have reported that screening with a fecal occult blood test (FOBT) has reduced CRC mortality and have suggested FOBT as a suitable population-based screening test for CRC. [3][4][5] Screening for CRC with FOBT not only leads to the detection of advanced CRCs, but also results in detection at earlier clinical stages. 6 Another advantage of screening with FOBT is that the removal of adenomatous, precancerous polyps can decrease the incidence of CRC 7,8 and consequently reduce mortality from CRC. 9 In particular, immunochemical FOBT (iFOBT) has been shown to be more sensitive than guaiac-based FOBT. 10 Reduced mortality and the detection of CRC in earlier stages results in high costeffectiveness and lowered health costs for both patients and the government. 11 In Chile, a prospective mult...

“…Diversos factores genéticos y mediambientales han sido asociados al desarrollo de este tumor, inlcuyendo la dieta rica en proteí-nas y grasas, baja ingesta de fibras, estilo de vida sedentario, obesidad y tabaquismo 2 . Durante las dos últimas décadas, la mortalidad por CCR se ha incrementado significativamente en países de América del Sur como Chile y Brasil, entre otros 3,4 . El incremento en la esperanza de vida, así como la mayor prevalencia de los factores de riesgo medioambientales, podrían explicar esta .…”

Increasing crude and adjusted mortality rates for colorectal cancer in a developing South American country

Abstract: The crude mortality rate from CRC has doubled in Chile in this period. After adjustment of mortality rates, it appears that much of this increase is due to the aging population. However, part of this increase could be explained by other factors.
