Clinical risk factors and survival analysis of postoperative recurrence or metastasis of colorectal cancer

Q: What does the study focus on in colorectal cancer patients?

The study focuses on clinical risk factors related to postoperative recurrence or metastasis of colorectal cancer and how these factors relate to outcomes.

Q: Which factors were reported as independent risk factors for postoperative recurrence or metastasis?

Mesocolon fascia infiltration, total number of lymph nodes, number of metastatic lymph nodes, and tumor TNM stage were reported as independent risk factors for postoperative recurrence or metastasis.

Postoperative recurrence or metastasis is a major determinant of survival in colorectal cancer patients. This study retrospectively included patients who underwent colorectal cancer surgery between January 2016 and December 2020, analyzing recurrence or metastasis, liver metastasis, lung metastasis, and death. Multivariate logistic regression identified mesocolon fascia infiltration, lymph node counts, metastatic lymph node number, and tumor TNM stage as independent risk factors for postoperative recurrence or metastasis.

Methods Patients who underwent colorectal cancer surgery between January 2016 and December 2020 were included. Multivariate Logistic regression was used to analysis statistically, including recurrence or metastasis, liver metastasis, lung metastasis and death respectively. Results 419 cases of colorectal cancer were included in the clinical study according to the screening criteria. Multivariate Logistic regression analysis showed that Mesocolon fascia infiltration (OR,2 . 769; 95%CI, 1.374–5. 579, P = 0 . 004), Total number of lymph nodes (OR,0 . 949; 95%CI, 0 .99–0. 988, P = 0 . 011), The number of metastatic lymph nodes (OR,1 . 173; 95%CI, 1.063–1. 294, P = 0 . 001), Tumor TNM stage (P < 0. 001), were independent risk factors for postoperative recurrence or metastasis of colorectal cancer. Mesocolic fascia infiltration (OR,3 . 113; 95%CI, 1.209–8. 015, P = 0 . 019) and TNM stage (P = 0 . 014) were independent risk factor for postoperative liver metastasis of colorectal cancer. TNM stage of tumor (P = 0 . 037) was an independent risk factor for pulmonary metastasis after colorectal cancer surgery. Conclusions Multifactor logistic regression analysis showed mesocolon fascia infiltration, total number of lymph nodes, the number of metastatic lymph nodes and tumor TNM stage were independent risk factor for postoperative recurrence and metastasis of colorectal cancer.

BMC Cancer (2026) 26:427 Introduction Colorectal cancer is one of the major gastrointestinal malignancies threatening human death worldwide. According to the International Agency for Research on Cancer (IARC) statistics, the number of new colorectal cancer cases in 2020 will be 1,931,600, accounting for 10% of the total number of new cancers worldwide [1]. Colorectal cancer is mainly treated by surgery, combined with chemotherapy, radiation therapy, targeted therapy and other comprehensive treatment. However, the local recurrence rate of colorectal cancer after radical surgery is about 4% to 30%. Data collected since 1990 show that the 5-year survival rate of patients w
