“…Median age of the patients with polyps was similar to other studies, in which the mean ranged from 57.5 and 62.5 years 7,9,19 . Thus, the prevalence of the disease is higher among individuals over 50 years old 1,4,6,7,20 .…”

“…Most of the patients who had polyps were females. The relation between gender and the development of polyps is not clear yet, but some studies point to higher prevalence rates among men 2,4,5,7,19 . This difference in our findings in comparison to literature is possibly due to the higher number of colonoscopies performed in women than in men in the analyzed service.…”

Adenocarcinoma represents 96-98% of colorectal neoplasms, and neoplastic polyps (adenomas) are their precursors. The aim of this study is to correlate size, location and histologic type of colorectal polyps at the presence of dysplasia and adenocarcinoma. Methods: Colonoscopies from January/2007 to December/2008 were retrospectively studied, in order to evaluate the characteristics of the polyps. Results and Discussion: Out of the 2,401 analyzed colonoscopies, 583 (24.3%) presented polyps. Due to the lack of histopathologic data, 139 exams were excluded. Mean age of the patients was 58±12 years, and 60% were females. Polyps were prevalent in the left colon (38.5%) and rectum (32.5%). Out of the 850 polyps which were histologically examined, 55.17% were tubular adenomas; 21.88%, hyperplastic; 17.05%, serrated; 5.4%, tubulovillous; and 0.47%, villous. As to polyps £1.0 cm, dysplasia was observed in 16.0% and adenocarcinoma in 1.9%. Those >1.0 cm, 72.0% (p<0.001) presented dysplasia, and 25.3% (p<0.001) presented adenocarcinoma. Polyps in the right and transverse colon were strongly associated with dysplasia (17.8% and 16.7%). Adenocarcinomas were prevalent in the left colon (2.5%) and rectum (2.1%). Conclusion: Polyps were more frequent in the left colon and rectum. The right and transverse colons were strongly correlated with dysplasia. Those of the left colon and rectum were associated with adenocarcinoma. Lesions >1.0 cm were positively related to dysplasia and neoplasm.
O adenocarcinoma representa 96-98% do câncer colorretal, sendo os pólipos neoplásicos (adenomas) seus precursores. O objetivo desse estudo é correlacionar tamanho, localização e tipo histológico de pólipos colorretais com a presença de displasia e adenocarcinoma. Métodos: Estudou-se retrospectivamente colonoscopias realizadas entre janeiro/2007 e dezembro/2008, avaliando-se as características dos pólipos. Resultados e Discussão: Das 2401 colonoscopias analisadas, 583 (24,3%) apresentaram pólipos. Por falta de dados histopatológicos, excluiu-se 139 exames. A média de idade foi 58±12 anos, sendo 60% mulheres. Houve predomínio no cólon esquerdo (38,5%) e reto (32,5%). Quanto ao tamanho, 86,58% eram £1 cm. Dos 850 pólipos analisados histologicamente, 55,17% eram adenomas tubulares, 21,88% hiperplásicos, 17,05% serrilhados, 5,4% tubulovilosos e 0,47% vilosos. Dos pólipos £1,0 cm, 16,0% apresentaram displasia e 1,9% adenocarcinoma; dos >1,0 cm houve displasia em 72,0% (p<0,001) e adenocarcinoma em 25,3% (p<0,001). Pólipos do cólon direito e transverso associaram-se mais à displasia (17,8% e 16,7%, respectivamente). Adenocarcinoma predominou no cólon esquerdo (2,5%) e reto (2,1%). Conclusão: Os pólipos predominaram em cólon esquerdo e reto. Os do cólon direito e transverso correlacionam-se fortemente à displasia, e os do reto e cólon esquerdo ao adenocarcinoma. Lesões maiores que 1,0 cm associaram-se positivamente com a presença de displasia e neoplasia

Esta investigación tuvo como objetivo analizar las características sociodemográficas y clínicas, tabaquismo, alcoholismo, práctica de ejercicios físicos de pacientes sometidos a colonoscopia, en el período de febrero a junio de 2012. Se ha observado que en los 84 pacientes entrevistados los síntomas de mayor prevalencia que llevaron a la indicación de la Colonoscopia fueron el dolor abdominal con 39 (46,4%). De los entrevistados cinco (6%) presentaron cáncer colorrectal (CCR), y la historia familiar de esta neoplasia fue relatada por 18 (21,4%) personas y la neoplasia en cuestión apareció en cinco (6%) de los encuestados, el tabaquismo estuvo presente en 17 (20,2%) de los pacientes y el consumo de bebida alcohólica fue negada por 26 (31%) de los entrevistados. En relación a la práctica de actividad física 71 (84,5%) de los pacientes eran insuficientemente activos.

Context Colorectal cancer is the third leading cause of death from malignancy in the world and the fourth leading cause in Brazil's ranks. Adenomatous polyps are considered premalignant lesions, and its resection reduces both morbidity and mortality rates. Objectives Investigate the prevalence of premalignant lesions and correlate it with age and gender, as well as with the lesion found profile: location, morphology, histology and grade dysplasia. Methods This was a retrospective, observational and descriptive study. We analyzed and tabulated results of polyps reports sent to Pathology Laboratory in the period ranging from January 1 to December 31, 2013, in Curitiba, Paraná, Brazil. Results We analyzed 4640 reports of colorectal polypectomy, coming from 3089 patients, of whom 97.6% were examined by colonoscopy. Concerning gender, 56.5% were female and 43.5% were male. The mean age was 57.6 years (ranging from 15 to 92 years). The predominant removal areas of polyps were rectum in 26.2% and sigmoid in 24.2% cases. About histological aspects, the most common type – adenoma – was present in 75.1% polyps, of which 74.2% were tubular and 21.7% were serrated. Among the non-adenomatous polyps, hyperplastic prevailed with 88.7% cases. Malignancy was observed in 100 cases (2.15%). Conclusion This study showed higher incidence of colorectal polyps in women, although adenocarcinomas are equally distributed in both sexes. In addition, the average age of patients undergoing colonoscopy is decreasing. Furthermore, 2.15% polyps sent for pathology analysis were found to be malignant.
