Expression of a CD44 variant containing exons 8 to 10 is a useful independent factor for the prediction of prognosis in colorectal cancer patients.

PURPOSE To determine the expression of the CD44 variant containing a variant exon 8 to 10 product (CD44v8-10) in colorectal cancer and to evaluate its prognostic value. MATERIALS AND METHODS CD44v8-10 was studied in resected tumors and normal mucosae obtained from 215 colorectal cancer patients (118 colon cancer and 97 rectal cancer). The expression of CD44v8-10 was analyzed immunohistochemically using the anti-CD44v8-10 monoclonal antibody (mAb) 44-1V. RESULTS One hundred of 215 cancer tissues expressed CD44v8-10. Positive staining was intense mainly on the cell membranes. There was no significant correlation between expression of CD44v8-10 and histologic type, primary tumor, lymphatic invasion, venous invasion, or peritoneal invasion. There were significant correlations between CD44v8-10 immunoreactivity and both lymph node and hematogenous metastasis. Patients with CD44v8-10-positive tumors had a greater relative risk of death compared with those whose tumors were CD44v8-10-negative. Among 169 patients who underwent curative resection, CD44v8-10 expression correlated with a high recurrence rate. The 5- and 10-year survival rates were 90.3% of patients with CD44v8-10-negative tumors, and 72.1% and 58.0% of those with CD44v8-10-positive tumors, respectively; these differences between the two groups of patients were significant (P < .01). In multivariate analysis using the Cox regression model, CD44v8-10 expression emerged as an independent prognostic indicator. CONCLUSION The results suggest that CD44v8-10 plays a role in metastasis of colorectal cancer, and tha CD44v8-10 expression may be a biologic marker of prognostic significance.

Background: In Malaysia, colorectal cancer is the second most common type of cancer for both sexes, represents 10.2% of total cancer cases in Malaysia. This study aims to identify the effect of individual-level factors on survival prognosis for patients with colorectal cancer in Malaysia.Methods: The study involved 4412 of colorectal cancer patients in Malaysia with histologically verified primary colorectal cancer, diagnosed between 2008 and 2013 (ICD-10, C18-C20), recorded in the database of National Cancer Patient Registry- Colorectal Cancer (NCPR-CC) Malaysia. We investigated the effect of individual characteristics such as age, gender, education as well as clinical characteristics such as cancer staging, cancer site and treatment modalities on survival prognosis after a diagnosis of colorectal cancer using a Cox regression survival model.Results: Patients diagnosed at stage IV had an almost 6-fold greater risk of dying from colorectal cancer than those with stage I. Age, third-degree education, poor tumour differentiation, the presence of distant metastases and receiving ‘other’ treatments were the other factors that increased the risk of death for colorectal cancer patients in Malaysian population.Conclusions: Our analysis revealed that the severity of the disease lead to poor prognosis in colorectal cancer in the population after adjusting for other individual characteristics. Health education programs targeting high risk group and emphasizing the importance of early detection of cancer as well as knowledge on the importance of cancer treatment should be implemented. Formulation of a better screening program needs to be extended so that it is a genuinely national program.

The Impact

A drastic difference exists between the 5-year survival rates of colorectal cancer patients with localized cancer and distal organ metastasis. The liver is the most favorable organ for cancer metastases from the colorectum. Beyond the liver-colon anatomic relationship, emerging evidence highlights the impact of liver immune microenvironment on colorectal liver metastasis. Prior to cancer cell dissemination, hepatocytes secrete multiple factors to recruit or activate immune cells and stromal cells in the liver to form a favorable premetastatic niche. The liver-resident cells including Kupffer cells, hepatic stellate cells, and liver-sinusoidal endothelial cells are co-opted by the recruited cells, such as myeloid-derived suppressor cells and tumor-associated macrophages, to establish an immunosuppressive liver microenvironment suitable for tumor cell colonization and outgrowth. Current treatments including radical surgery, systemic therapy, and localized therapy have only achieved good clinical outcomes in a minority of colorectal cancer patients with liver metastasis, which is further hampered by high recurrence rate. Better understanding of the mechanisms governing the metastasis-prone liver immune microenvironment should open new immuno-oncology avenues for liver metastasis intervention.

Abstract Background Serum bilirubin and total bile acid (TBA) levels have been reported to be strongly associated with the risk and prognosis of certain cancers. Here, we aimed to investigate the effects of pretreatment levels of serum bilirubin and bile acids on the prognosis of patients with colorectal cancer (CRC). Methods A retrospective cohort of 1474 patients with CRC who underwent surgical resection between January 2015 and December 2017 was included in the study. Survival analysis was used to evaluate the predictive value of pretreatment levels of bilirubin and bile acids. X-Tile software was used to identify optimal cut-off values for total bilirubin (TBIL), direct bilirubin (DBIL) and TBA in terms of overall survival (OS) and disease-free survival (DFS). Results DBIL, TBIL, and TBA were validated as significant prognostic factors by univariate Cox regression analysis for both 3-year OS and DFS. Multivariate Cox regression analyses confirmed that high DBIL, TBIL and TBA levels were independent prognostic factors for both OS (HR: 0.435, 95% CI: 0.299–0.637, P < 0.001; HR: 0.436, 95% CI: 0.329–0.578, P < 0.001; HR: 0.206, 95% CI: 0.124–0.341, P < 0.001, respectively) and DFS (HR: 0.583, 95% CI: 0.391–0.871, P = 0.008; HR:0.437,95% CI: 0.292–0.655, P <0.001; HR: 0.634, 95% CI: 0.465–0.865, P = 0.004, respectively). In addition, nomograms for OS and DFS were established according to all significant factors, and the c-indexes were 0.819 (95% CI: 0.806–0.832) and 0.835 (95% CI: 0.822–0.849), respectively. Conclusions TBIL, DBIL and TBA levels are independent prognostic factors in colorectal cancer patients. The nomograms based on OS and DFS can be used as a practical model for evaluating the prognosis of CRC patients.
