Age and Gender in Relation to Colorectal Cancer in Najef Province: A Histopathological Study

Colorectal cancer (CRC), which is also referred to colorectal adenocarcinoma, occurs when the growth of cells goes out of control in the colon or rectum. A number of histological colorectal carcinoma are listed, such as mucinous, signet ring cell, and moderately
differentiated adenocarcinoma. The present study included fifty tissue blocks (16 females and 34 males) of patient groups with CRC and thirty five tissue blocks of colon tissue (ulcerative colitis) which were used as control group. The mean age of patients group was
51.44 ± 16.67 years. The majority of patients with colonic carcinoma were above the age of 40, accounting for 80%, while 20% of cases were below the age of 40 years. A recto-sigmoid location is the most common site for colonic tumors accounting for 60%. Grade of tumor was well differentiated in 56%, and the following features were observed: The tissue appears with multi-layering, back to back arrangement (little intervening stroma), loss of polarity, loss of goblet cells, and invasion of stroma and presence of nuclear
criteria of malignancy: hyperchromatism, high N/C ratio visible nucleoli and abnormal mitosis. The present results also showed that in grade I lesion, most of tumor retains glandular pattern, moderately differentiated in 28%, and tumor is nearly equally composed of glandular and solid patterns. However, the poorly differentiated was 16% with same cellular criteria of malignancy but almost all
the tumor was composed of solid areas. The present findings divided the stage of tumor patients into: 22% stage I; 66% stage II, and 12% stage III.
