Awareness about characteristics of colorectal tumors at different anatomical sites enables better cancer control strategies.This study aimed to compare the clinicopathologic features of cecal and rectal cancers.</span><br> <span style="line-height:13.0pt"><b><i><span style="color:blue">Methods:</span></i></b> In this cross-sectional study, Demographic, clinical and pathologic information of patients with newly diagnosed rectal and cecal cancer were statistically compared, using SPSS software.</span><br> <span style="line-height:13.0pt"><b><i><span style="color:blue">Results:</span></i></b> 98 patients with cancer of rectum and 53 patients with cancer of cecum were included, the mean age of patients with cecal cancer was significantly higher than rectal cancer (P= 0.012)<b> </b>and the odds of cecal cancer in patients older than 50 years old was two times more than the younger ones<b>. </b>The number of male patients was significantly higher than female patients in rectal cancer group comparing with cecal cancer group (P=0.016). 41.8% of patients with cecal cancer and 20.8% of patients with rectal cancer had smoking risk factor (P=0.012). Abdominal pain was more frequent in cecal cancer group (P=0.007) and the proportion of rectal bleeding was significantly higher in rectal cancer group (P=0.006). In terms of histopathologic findings, rectal tumors tend to be more differentiated than cecal cancers (P= 0.004).</span><br> <span style="line-height:13.0pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> Despite the differences of proximal and distal colorectal cancers, due to the lack of enough evidence in this area, it is not possible yet to conclude whether rectal and colon cancer are distinct diseases or not.</span></span></span><br> &nbsp; Rectal Cancer,Cecal cancer, colorectal cancer, cancer of cecum,cancer of rectum,clinicopathologic features 544 548 http://caspjim.com/browse.php?a_code=A-10-1367-6&slc_lang=en&sid=1 Javad Shokri Shirvani javadshokry@gmail.com 100319475328460057779 100319475328460057779 No Clinical Research and Development Unit of Rouhani University Hospital, Babol University of Medical Sciences, Babol,I.R.Iran Catherine Behzad catherinebehzad@yahoo.com 100319475328460057780 100319475328460057780 Yes Clinical Research and Development Unit of Rouhani University Hospital, Babol University of Medical Sciences, Babol,I.R.Iran Moein Shirchi moeinshirchisasi@gmail.com 100319475328460057781 100319475328460057781 No Student Research Committee, Babol University of Medical Sciences, Babol, Iran Mohammad Ranaee drm.ranaee55@gmail.com 100319475328460057782 0009-0002-3155-0008 No Clinical Research and Development Unit of Rouhani University Hospital, Babol University of Medical Sciences, Babol,I.R.Iran Hemmat Ghoinia h_gholinia@yahoo.com 100319475328460057783 100319475328460057783 No Clinical Research and Development Unit of Rouhani University Hospital, Babol University of Medical Sciences, Babol,I.R.Iran
