Introduction:The presence of tumor budding, i.e.,single cancer cells or a nest of poorly differentiated cells at the front of tumor invasion appears to be a new histopathological indicator of increased aggressiveness of colorectal carcinoma. Purpose: The aim of this work was a retrospective evaluation of the invasion front (tumorbudding, vascular invasion,and lymphocytic infiltration) in postoperative biopsies of patients with colorectal carcinoma and analysis of the 5-year survival. Materialsand methods:The study was based on the material received after surgical treatment of 164 patients with colon cancer. Tissue was obtained directly following tumor resection, fixed in 10% formaldehyde and embedded in paraffin blocks using a routine method by melting with paraffin at a temperature of 56º C. These samples were then routinely stained with haematoxylin and eosin and underwent a histopathological evaluation, with particular attention being paid to the invasion front of the tumor. The immunohistochemical expression of cytokeratin 20 was also evaluated using anti-human CK20 monoclonal antibody (clone Ks.20.8, Dako, Poland). Results: Tumor budding was found in 124 out of 164 patients. Statistical analysis showed a correlation between the presence of tumor budding TB and depth of invasion (pT), lymph node metastasis, distant metastasis, lymphocytic infiltration,and vascular invasion. The cumulative five-year survival correlated with the lack of tumor budding and vascular invasion, as well as a decrease in lymphocyticinfiltration.

BACKGROUND: Tumor budding is associated with adverse histology and is a predictor of lymph node metastasis. Human chorionic gonadotropin-beta (hCG-β) expression in non-trophoblastic tumors has been associated with aggressive behavior. AIM: Evaluation of tumor budding and hCG-β _immunohistochemical expression in colorectal carcinoma (CRC), and correlation of their expression with various clinicopathological parameters. MATERIALS AND METHODS: Immunohistochemical staining for hCG-β _was performed on paraffin-embedded sections of 60 cases of CRC. Tumors with cytoplasmic or membranous staining of more than five epithelial cell clusters were designated hCG-β _positive; otherwise, they were designated hCG-β _negative. Tumor budding was assessed in hematoxylin and eosin stained slides and was classified as; low: 0–4 buds, intermediate: 5–9 buds and high: ≥10 buds; with exclusion of pure mucoid or signet ring cell morphology cases from analysis. RESULTS: Tumor budding was low in (58.8%) of the cases, intermediate in (15.7%), and high in (25.5%). There was a statistically significant correlation between tumor budding and tumor histological grade (p = 0.011), lymph node metastasis (N) (p = 0.009), overall pathologic stage group (p = 0.009), modified Dukes’ stage (p = 0.009), lymphovascular invasion (p = 0.000), and desmoplastic reaction (p = 0.004). Positive hCG-β _alpha expression was detected in 12 (20%) of cases. There were statistically significant correlations between hCG-β _expression and each of lymphovascular invasion (p = 0.042) and tumor budding (p = 0.000). CONCLUSION: hCG-β _is a marker of aggressiveness that may have essential role in tumor invasion. Tumor budding is crucial event in tumor invasion and metastasis. Tumor budding with hCG-β _expression is a novel prognostic parameter and may represent a potential therapeutic target.
