A follow-up study has been carried out to assess the association between MTHFR polymorphisms (SNPs) and overall survival (OS) of colorectal cancer (CRC) patients. Data on 411 CRC patients after surgery were tested for the MTHFR 677C > T and 1298A > C polymorphisms. For MTHFR C677T, patients with CT genotype (HR = 1.17; 95 % CI 0.77-1.80) and those with TT genotype (HR = 1.09; 95 % CI 0.67-1.75) had no statistically significant greater risk of dying than those with wild-type genotype. For MTHFR A1298C, the HRs of AC and CC genotype were 1.09 (95 % CI 0.75-1.59) and 0.79 (95 % CI 0.48-1.29) comparing with AA genotype. In the subgroup, 183 patients received chemotherapy treatment, and the HRs of patients with CT and TT genotype were 0.93 (95 % CI 0.50-1.72) and 0.86 (95 % CI 0.44-1.68) for MTHFR C677T. For A1298C polymorphism, AC genotype (HR = 1.39; 95 % CI 0.81-2.39) and CC genotype (HR = 1.22; 95 % CI 0.75-2.00) did not show significant differences. In conclusions, no significant association was observed between the 677C > T and 1298A > C polymorphisms of MTHFR and the prognosis of colorectal cancer patients with curative resection, including all the subjects and the subgroup of chemotherapy.

Background: Bacterial toxins are emerging as promising hallmarks of colorectal cancer (CRC) pathogenesis. In particular, Cytotoxic Necrotizing Factor 1 (CNF1) from E. coli deserves special consideration due to the significantly higher prevalence of this toxin gene in CRC patients with respect to healthy subjects, and to the numerous tumor-promoting effects that have been ascribed to the toxin in vitro.

Objective: The clinical benefits of neoadjuvant bevacizumab plus chemotherapy in locally advanced gastric cancer patients are controversial. This study intended to evaluate the efficacy and safety of neoadjuvant bevacizumab plus chemotherapy in these patients.
Methods: In this retrospective study, 71 locally advanced gastric cancer patients receiving neoadjuvant bevacizumab plus chemotherapy or neoadjuvant chemotherapy alone were divided into bevacizumab plus chemo group (N = 23) and chemo group (N = 48).

Background: Tumor microenvironment (TME), particularly immune cell infiltration, programmed cell death (PCD) and stress, has increasingly become a focal point in colorectal cancer (CRC) treatment. Uncovering the intricate crosstalk between these factors can enhance our understanding of CRC, guide therapeutic strategies, and improve patient prognosis.
Methods: We constructed an immune-related cell death and stress (ICDS) prognostic model utilizing machine learning methodologies.

Background: DNA hypomethylation and uracil misincorporation into DNA, both of which have a very important correlation with colorectal carcinogenesis. Folate plays a crucial role in DNA synthesis, acting as a coenzyme in one-carbon metabolism, which involves the synthesis of purines, pyrimidines, and methyl groups. MTHFR, a key enzyme in folate metabolism, has been widely studied in relation to neural tube defects and hypertension, but its role in colorectal cancer remains underexplored.

Background: Early detection and diagnosis of cancer are vital to improving outcomes for patients. Artificial intelligence (AI) models have shown promise in the early detection and diagnosis of cancer, but there is limited evidence on methods that fully exploit the longitudinal data stored within electronic health records (EHRs). This review aims to summarise methods currently utilised for prediction of cancer from longitudinal data and provides recommendations on how such models should be developed.
