ObjectivesTo present 7 years data mentioning the spectrum of preneoplastic & neoplastic cases of intestine received at Dow Diagnostic Research and Reference Laboratory.MethodsAll the cases of preneoplastic & neoplastic lesions of intestine received during 2009 - 2015 were reviewed. The data obtained were subjected to descriptive statistical analysis using SPSS version 22. Furthermore, the association of diagnosis was seen with various other variables including age, gender & site of the lesion. A p-value of < 0.05 was considered as significant.ResultsThe total samples were 486, out of which 33 cases were of premalignant and 453 were of malignant lesions. Out of total 33 cases of premalignant lesions of intestine, it consisted adenomatous polyp = 39.4% (n=13), dysplasia = 36.4% (n=12) and adenoma = 24.2% (n=8). From the total of 453 cases diagnosed as malignant lesions; adenocarcinoma as Grade-I were 14.2% (n=64), Grade-II were 7.6% (n=260) and Grade-III were 22% (n=99). Squamous cell carcinoma Grade-I were 0.4% (n=2), Grade-II 1.6% (n=7) and Grade-III 0.9% (n=4). 2.4% (n=11) cases were of metastatic adoncarcinoma, 0.9% (n=4) were diagnosed as neuroendocrine tumors and 0.4% (n=2) as lymphoma. A significant association was seen between site of the tumor and diagnosis, rectum was the commonest site for adenocarcinomas (p=0.001). Moderately differentiated adenocarcinoma was predominantly present in young age (p=0.001).ConclusionColorectal carcinoma is on rise in Pakistan, predominantly in young males, and rectum being the commonest site. In our study, all the lesions showed male predominance with adenomatous polyp as the commonest premalignant lesion & Grade-II adenocarcinoma the most common malignancy of intestine.Copyright: © Pakistan Journal of Medical Sciences.
