The pathological examination of early colorectal cancer specimens, in particular ‘malignant polyps', provides important prognostic information. The depth of invasion into the submucosal layer assessed according to the Haggitt (for pedunculated lesions) or Kikuchi (for nonpolypoid lesions) classification systems or by direct measurement has been associated with the risk of lymph node metastasis. Angioinvasion, in particular lymphatic invasion, budding, tumor differentiation or grade, and resection margin status have been identified as further risk factors. The combination of these parameters allows the stratification of affected individuals into low- and high-risk categories, which is pivotal for clinical management. For low-risk cancers, defined as a completely excised Haggitt level 1-3/Kikuchi sm1 tumor with no evidence of poor differentiation or angioinvasion, local excision is generally regarded as adequate treatment. Oncological surgical resection is, however, indicated for high-risk cancers, which show at least one of the following features: Haggitt level 4/Kikuchi sm3 invasion, the presence of lymphatic (or vascular) invasion, poor differentiation, or positive resection margin. The inclusion of molecular markers such as tumor suppressor genes and their products, markers involved in tumor vascularization, and markers related to tumor cell adhesion and invasion may help to refine risk stratification, but data on molecular markers are still limited in this regard.

In the presence of unfavorable pathologic results after endoscopic resection of colorectal cancer, colectomy is routinely performed. We determined the risk factors for residual diseases in patients with colectomy after complete macroscopic endoscopic resection of early colorectal cancer. We identified consecutive patients who underwent endoscopic resection of early colorectal cancer and subsequently underwent colectomy, from January 2011 to December 2014. Clinicopathologic risk factors related to the residual disease were analyzed. In total, 148 patients underwent endoscopic resection and subsequent colectomy. Residual disease on colectomy was noted in 16 (10.9%) patients. The rates of poorly differentiated/mucinous histology (p=0.028) and of positive or unknown vertical resection margin (p=0.047) were higher in patients with residual disease than in those without. In multivariate analysis, a poorly differentiated/mucinous histology and positive or unknown vertical resection margin were significantly associated with residual disease (odds ratio = 7.508 and 2.048, p=0.015 and 0.049, resp.). After complete macroscopic endoscopic resection of early colorectal cancer, there is a greater need for additional colectomy in cases with a positive or unknown vertical resection margin or a poorly differentiated/mucinous histology, because of their higher risk of residual cancer and lymph node metastasis.

Abstract Background Estimating the risk of lymph node metastasis (LNM) is crucial for determining subsequent treatments following curative resection of early colorectal cancer (ECC). This multicenter study analyzed the risk factors of LNM and the effectiveness of postoperative chemotherapy in patients with ECC. Methods We retrospectively analyzed the data of 473 patients with ECC who underwent general surgery in five hospitals between January 2007 and October 2018. The correlations between LNM and sex, age, tumor size, tumor location, endoscopic morphology, pathology, depth of invasion and tumor budding (TB) were directly estimated based on postoperative pathological analysis. We also observed the overall survival (OS) and recurrence in ECC patients with and without LNM after matching according to baseline measures. Results In total, 473 ECC patients were observed, 288 patients were enrolled, and 17 patients had LNM (5.90%). The univariate analysis revealed that tumor size, pathology, and lymphovascular invasion were associated with LNM in ECC (P = 0.026, 0.000, and 0.000, respectively), and the multivariate logistic regression confirmed that tumor size, pathology, and lymphovascular invasion were risk factors for LNM (P = 0.021, 0.023, and 0.001, respectively). There were no significant differences in OS and recurrence between the ECC patients with and without LNM after matching based on baseline measures (P = 0.158 and 0.346, respectively), and no significant difference was observed between chemotherapy and no chemotherapy in ECC patients without LNM after surgery (P = 0.729 and 0.052). Conclusion Tumor size, pathology, and lymphovascular invasion are risk factors for predicting LNM in ECC patients. Adjuvant chemotherapy could improve OS and recurrence in patients with LNM but not always in ECC patients without LNM.

Univariate analysis revealed that tumor size, pathology, lympho-vascular invasion were associated with LNM in ECC (P = 0.026, 0.000, 0.000, respectively), and multivariate logistic regression confirmed that tumor size, pathology, lympho-vascular invasion were risk factors for LNM (P = 0.021, 0.023, 0.001, respectively). There were no significant differences for the OS and recurrence between the ECC patients with and without LNM whose base-lines were matched (P = 0.158,0.346, respectively), neither no significant difference between chemotherapy and no chemotherapy ECC patients without LNM after surgery (P = 0.729,0.052).Conclusion Tumor size, pathology, lympho-vascular invasion were risk factors for predicting LNM in ECC patients. Adjuvant chemotherapy could improve the overall survival and recurrence in patients with LNM, but no necessary for the ECC patients without LNM.

Abstract Aim There is an increase in the number of complex SPECC cases presented at colorectal MDT meetings with a wide variation in the treatments offered to patients, many of whom undergo high-risk and life-changing surgical resection. This study aimed to evaluate the detection, diagnosis and treatment of early colorectal cancer since the introduction of a SPECC MDT. Method This was a retrospective audit of 108 patients, from the SPECC MDT database from January 2014 to December 2019. Primary outcome assessed the recognition of lesions using endoscopy and radiological evaluation to assess depth of invasion and lymph node involvement. Secondary outcomes included definite treatment, pathological reporting and recurrence. Results Overall, mean age of 72, 79% had one or more significant co-morbidity. Clinical presentation; 61 asymptomatic, 46 symptomatic and 31 referred from the national bowel cancer-screening programme. All patients (n = 108) had endoscopic assessment the lesions were, 53% sessile and 47% pedunculated; 78% of the lesions were found in the rectum. We observed surgical management in 31 cases, endoscopic in 28, chemo-radiotherapy in 12 and 3 cases were palliative. However, 17 (n = 108) underwent failed endoscopic resection and required surgical intervention. Recurrence was observed in 17.6% of cases and mortality in 4%. Conclusions Pathological reports provide a definitive answer to questions of malignancy but SPECC can be challenging in all areas. A specialist MDT allows for appropriate assessment and treatment of lesions and leads to better patient outcomes.
