“…By adding the rectosigmoid junction to rectal primary site, the mean proportion of the rectum as the primary site increased to 42%. Only 4 studies, including 7561 patients provided a detailed information regarding the sublocation of colon primary site as follows: Sigmoid colon 43%, ascending clon 21%, cecum 21%, descending colon 12%, and transverse colon 3% (11,13,15,16,(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40).

Context:Colorectal cancer is one of the most common cancers and the leading cause of cancer death in Iran. This study aimed to identify the clinical and pathological characteristics, as well as survival rate of colorectal cancer in Iran. Evidence Acquisition: The articles published in PubMed without language and time restrictions were included in this review. Only original clinical articles were included in the review and non-clinical studies, including cellular, molecular, genetics, and animal reports, were excluded. The case reports, letters, reviews, and clinical reports with less than 100 patients were excluded, as well. All the clinical data regarding the patients' demographics, tumor characteristics, and survival rate were collected. Results: A total of 178 studies were identified at the initial step of literature search. After applying the inclusion and exclusion criteria, 27 studies, including 37901 patients were eligible. The mean age of the patients was 57.2 years, and the male-female ratio was 1.38. Colon, rectum, and rectosigmoid junction accounted for 58%, 28%, and 14% of all colorectal primary sites, respectively. Moreover, the average proportion of the patients with stages 0-I, II, III, and IV was 9%, 39%, 36%, and 16%, respectively. Besides, tumor grades 1, 2, and 3 were reported in 52%, 37%, and 11% of the patients, respectively. Adenocarcinoma (96.8%) was the most frequent histological type. The mean and median survival rate was 80.1 and 55.2 months, respectively. Additionally, the average 5-year overall survival rate was 52.5%. Conclusions: In Iran, colorectal cancer tends to manifest at locally advanced stage with poor prognosis. Therefore, public health strategies, such as screening programs, should be planned for early detection of this aggressive neoplasm.

“…Some stage III patients with inadequate lymph nodes evaluation may be incorrectly classified as stage I or II (4,10,11). N stage is the most important prognostic factor in resected lo-coregional colorectal cancer (12). Several studies have investigated the association between the number of lymph node identified and overall survival in patients with colorectal cancer (13).…”

Background:The extent of lymph node involvement is the most significant prognostic indicator in resected locoregional colorectal cancer. Objectives: This study aimed to investigate the prognostic value of total lymph nodes identified and ratio of lymph nodes in resected colorectal cancer. Patients and Methods: Two hundred seventy five patients with histologically proven resected locoregional invasive colorectal adenocarcinoma from 2003 to 2011 were included. All patients were treated with standard surgical resection for their colorectal cancer. Patients with incomplete data, or unresectable tumors or distant metastases were excluded from the study. All potential prognostic variables were evaluated for their impact on the local control, disease-free, and overall survival rates. Results: Of the 275 patients, 162 were men and 113 were women with a median age of 54 (range 23-84) years. The mean total lymph nodes were significantly higher in colon cancer than rectal cancer (11 versus 7.5, P = 0.001). In node positive (stage III) patients, the mean lymph nodes ratio was 0.5 for rectal cancers and 0.37 for colon cancers respectively showing a nonsignificant (P = 0.05) trend toward higher lymph nodes ratio in rectal cancer patients. In univariate analysis, the mean total number of lymph node identified was a prognostic factor for 5-year disease free (P = 0.04) and overall survival (P = 0.02) rates. In node positive patients, lymph nodes ratio was a prognostic factor for 5-year local control (P = 0.04), disease free survival (P = 0.01), and overall survival (P = 0.01) rates. On multivariate analysis, advanced primary tumor stage, rectal primary site and the presence of perineural invasion were independent adverse prognostic factors for overall survival. Conclusions: Total lymph nodes identified and ratio of lymph nodes are associated with oncological outcomes outcomes in patients with colorectal cancer.
