“…In fact, the adenoma and advanced adenoma rates among Latino participants in our study were comparable to those found in the Veterans Affairs Cooperative Study, which included a relatively higher risk population in that the majority were male and white [29]. Only the study of Thoma and coworkers reported adenoma rates higher than those found in the present study [24]. However, since their study was a retrospective analysis, it is possible that the subjects may not have all been average-risk and asymptomatic for CRC.…”

Background Colorectal cancer (CRC) is the second leading malignancy diagnosed among U.S. Latinos. Latinos in the U.S. represent a heterogeneous amalgam of subgroups varying in genetic background, culture, and socioeconomic status. Little is known about the frequency of CRC precursor lesions found at screening colonoscopy among Latino subgroups. Aim The aim was to determine the prevalence and distribution of histologically-confirmed adenomas found at screening colonoscopy among average-risk, asymptomatic U.S. Latinos according to their subgroup and socio-demographic background. Methods Cross-sectional analysis of pathological findings resulting from screening colonoscopy among average-risk, asymptomatic U.S. Latinos aged ≥ 50 in two prospective randomized controlled trials at an academic medical center. Results Among the 561 Latinos who completed screening colonoscopy, the two largest subgroups were Puerto Ricans and Dominicans. The findings among both subgroups were: adenomas 30.6%, proximal adenomas 23.5%, advanced adenomas 12.0%, and proximal advanced adenomas 8.9%. These rates are at least as high as those found at screening colonoscopy among U.S. whites. While Puerto Ricans were more likely than Dominicans to be born in the U.S., speak English, be acculturated, have a smoking history, and be obese, there were no significant differences in adenoma rates between these subgroups. Conclusions The prevalence of adenomas, advanced adenomas, and proximal neoplasia was high among both subgroups. These findings have implications for CRC screening and surveillance among the increasingly growing Latino population in the U.S.

“…Although one study observed a similar ADR for whites and Hispanic patients, another group observed a lower rate for white patients. 33,34 More studies are needed to confirm our findings among a broader population. However, although the absolute ADR may differ slightly between populations, the relative difference in ADR between surveillance and screening colonoscopies nonetheless may remain consistent.…”

BACKGROUND & AIMS The adenoma detection rate (ADR) is an important quality indicator originally developed for screening colonoscopies. However, it is unclear whether the ADR should be calculated using data from screening and surveillance examinations. The recommended benchmark ADR for screening examinations is 20% (15% for women and 25% for men ≥ 50 y). There are few data available to compare ADRs from surveillance vs screening colonoscopies. We used a population-based registry to compare ADRs from screening vs surveillance colonoscopies. The serrated polyp detection rate (SDR), a potential new quality indicator, also was examined. METHODS By using data from the statewide New Hampshire Colonoscopy Registry, we excluded incomplete and diagnostic colonoscopies, and those performed in patients with inflammatory bowel disease, familial syndromes, or poor bowel preparation. We calculated the ADR and SDR (number of colonoscopies with at least 1 adenoma or serrated polyp detected, respectively, divided by the number of colonoscopies) from 9100 colonoscopies. The ADR and SDR were compared by colonoscopy indication (screening, surveillance), age at colonoscopy (50–64 y, ≥65 y), and sex. RESULTS The ADR was significantly higher in surveillance colonoscopies (37%) than screening colonoscopies (25%; P < .001). This difference was observed for both sexes and age groups. There was a smaller difference in the SDR of screening (8%) vs surveillance colonoscopies (10%; P < .001). CONCLUSIONS In a population-based study, we found that addition of data from surveillance colonoscopies increased the ADR, but had a smaller effect on the SDR. These findings indicate that when calculating ADR as a quality measure, endoscopists should use screening, rather than surveillance colonoscopy, data.

Screening Colonoscopy among Uninsured and Underinsured Urban Minorities

Background/AimsUninsured individuals have lower rates of screening colonoscopy (SC), and little is known regarding the pathology results obtained when they undergo colonoscopies. Since 2004, we have participated in a program that offers SC to uninsured New Yorkers; herein, we report our findings.MethodsUninsured, average-risk patients who were at least 50 years of age underwent SC at our institution between April 2004 and June 2011. We analyzed polyp pathology, location, size, incidence of adenomas, and incidence of adenomas with advanced pathology (AAP) with respect to ethnicity, gender, and age.ResultsOut of 493 referrals, 222 patients completed the colonoscopies. Polyps were identified in 21.2% of all patients; 14% had adenomas, and 4.5% had AAP. The rates of adenomas among African-Americans, Hispanics, and Whites were 24.3%, 12.1%, and 11.6%, respectively, and the corresponding rates of AAP were 10.8%, 3.5%, and 2.3%. Differences in the polyp type, location, and AAP did not reach statistical significance with respect to ethnicity or gender. Patients aged 60 and older were found to have a higher rate of advanced adenomas compared with younger patients (8.6% vs 2.6%, p=0.047).ConclusionsFurther efforts to fund screening colonoscopies for uninsured individuals will likely result in the identification of advanced lesions of the colon before they progress to colorectal cancer.
