Background/Aim. Adenocarcinomas of the colon are the most common malignant colorectal tumors. Macroscopic and histopahtological features of colorectal cancer significantly affect its outcome. The aim of this study was to analyze the impact of histopahological finding as a prognostic factor on the surgical treatment outcome and the course of the disease. Methods. In the first part of this study the distribution (numerical and proportional) of certain histopathological parameters in the examined groups of patients were reviewed; in the second part of the study the statistical significance of the impact of the certain elements of a histopahtological finding on the surgical treratment outcome was analyzed. The histopathological elements analyzed included: the hsitological tumor type grading according to Duke, ie Astler-Coller, and tumor, nodes, metastases (TNM) staging in the examined sample of 100 patients. Results. Statistically significant prognostic factors of the outcome of surgical treatment were selected after multivariant analysis. These factors comprise Astler-Coller-Dukes stage D (revealed in 77.78% patients died), stage IV according TNM classification (T1-4, N0-2, M1), histological structure (poorly diferentiated adenocarcinoma in 85.2% patents died) and type of tumor (mucynous adenocarcinoma was more often present in died, 77.78%). Since ? = 0.000 for four risk factors were formed using discriminant analysus, it was proved their significant influence on the outcome of surgical treatment. Discriminant coefficient showed that the greatest influence on surgical treatment were registred in patients with tumor of Astler-Coller-Dukes stage D (0.255), poorly differentiated adenocarcinoma (histological structure) (0.139), mucynous adenocarcinoma (type of tumor) (0.074) and stage IV according to the TNM elassification (T1-4, N0-2, M1) (0.39). Conclusion. The prognostic factors influencing the outcome of surgery for colorectal carcinoma were defined. Patients with pathohistological finding of Astler-Coller-Dukes stage D, stage IV according to the TNM classification (T1-4, N0-2, M1) and poorly differentiated adenocarcioma have statistically highly significant mortality during the perioperative course of the disease.

Abstract Background The risk of colorectal cancer (CRC) development has been related to telomere dysfunction and obesity. However, prognosis of patients affected by CRC has not clearly established considering both telomere attrition and obesity status. Previous published data highlights the importance of studying how obesity influences telomere function and its potential role as a predictor of prognosis in CRC. The aim of this study was to evaluate the impact of obesity and telomere status in the prognosis of patients affected by CRC and submitted to curative surgical treatment. Methods We performed a prospective study including 162 CRC patients submitted to curative surgical treatment. Samples were obtained from tumor and non-tumor tissues. Subjects were classified according to their Body Mass Index (BMI). Telomere status was established through telomere length and telomerase evaluation. Statistical analyses were performed using the SPSS software package version 22. Differences in two or more groups of study were calculated by parametric or non-parametric tests, depending on normality and homoscedasticity conditions of the variables. Prognosis was analyzed using the Kaplan-Meier method. The potential prognostic impact of the variables considered in this work jointly, was evaluated by Cox multivariate regression analyses. Results Patients with shorter telomeres, both in the tumor (median telomere length < 6.5 kb) and their non-tumor paired tissues (median telomere length < 7.1 kb), had the best clinical evolution, independently of the Dukes' stage of cancers (P = 0.025, for tumor samples; P = 0.003, for non-tumor samples). Telomere shortening was inversely associated with BMI in CRC patients. Also, subjects with a BMI > 31.85kg/m 2 showed the worse clinical outcomes. Of interest, the impact of BMI showed gender dependence, since only the group of men showed significant differences in CRC prognosis in relation to obesity status (P = 0.037). Conclusions Telomere length constitutes a useful biomarker to predict prognosis in CRC. Independently of BMI values, the better clinical evolution was associated with shorter telomeres. Obesity seems to have an impact on the clinical outcomes of CRC; however, the impact of BMI seems to be related to other factors such as gender.

One of the factors affecting the effectiveness of treatment and determining the prognosis of a patient with colorectal cancer may be inflammatory status both before and after surgical treatment. The review is devoted to the description of possible mechanisms of relationa between patient's inflammatory status and oncogenesis. Particular attention is paid to the ability of tumor cells to modify the immune cells from the antioncogenic to prooncogenic status. The paper makes an attempt to present a unified concept of the impact of postoperative complications on tumor recurrence in the light of the inflammatory response to surgical intervention.

There are presented results of surgical treatment of 347 patients with colorectal cancer. Based on the retrospective analysis a comparative study of results of surgical treatment for colorectal cancer using laparoscopic technologies and “open” access was carried out. Predictive factors that correlate with the risk of postoperative complications with laparoscopic and “open” access at the surgical stage of treatment for colorectal cancer were determined.

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.
