Objective: To determine the effect of intraperitoneal chemotherapy (IPC) with mitomycin C on expression of intraperitoneal cancer cells markers in patients with T4 colon cancer.
Material And Methods: For the period from January 2019 to April 2020, 65 patients with T4 colon cancer were included in prospective comparative study. There were 46 patients in the main group and 19 patients in the control group. In the main group, surgical procedure was followed by IPC with mitomycin C. No IPC was performed in the control group. An effectiveness of IPC was evaluated using CD133, CD24, CD26, CD44, CD184 markers expression in peritoneal lavages.
Results: Significant between-group differences were observed for CD133 (=0.0168), CD24 (=0.0455) and CD44 (=0.0012). There was a tendency to decrease in the level of CD184 expression in both groups in the second lavage (=0.0605).
Conclusion: IPC in patients with T4 colon cancer can reduce the expression and proliferative potential of free cancer cells.

Background And Objective: Cancer is one of the most difficult diseases facing modern medicine, and increasing amounts of research and clinical treatments are being applied to the treatment of cancer. Immunotherapy, particularly immune checkpoint inhibitor (ICI) therapy, has revolutionized the treatment and overall survival of patients with several different types of cancer. Approximately one-third of patients treated with ICIs may experience immune-related adverse events (irAEs).

The relationship between cancer and thrombosis was initially highlighted in the 19th century. Vascular complications in oncology can be arterial or venous thrombosis, and incidental pulmonary embolism is a growing challenge. We aimed to describe the frequency and clinical characteristics of cancer patients with incidental venous thromboembolism (iVTE).

Colon neoplasia is one of the major malignancies in industrialized countries due to their Western-style food habits. It accounts for more than 50% of the population developing adenomatous polyps by the age of 70 years, but 10% of cancers in developed countries. The aim of this study was to evaluate the pathological role of the C-X-C chemokine receptor type 4/stromal-derived factor 1 axis (CXCR4-SDF-1 axis), and the inhibitory molecules PD-1 and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) in postoperative colon cancer patients undergoing treatment with chemotherapy (oxaliplatin and capecitabine) and estimate the correlation between these studied factors to deeply understand the basic mechanisms and potential diagnostic or therapeutic effects.

Background: Colorectal cancer (CRC) causes substantial morbidity and mortality internationally. In Hungary, the incidence and mortality of CRC are among the world's highest. Fortunately, CRC is a highly preventable disease, since there is a long asymptomatic phase before neoplastic transformation.

Background: Metastatic colon cancer (MCC) is a debilitating condition with a poor prognosis. Currently, there is limited data that investigates MCC in relation to mismatch repair (MMR) status. The aims of this study are to compare sociodemographic and clinicopathologic features and mortality between patients with MMR-proficient (MMR-P) and MMR-deficient (MMR-D) MCC.
