Background: To evaluate the prognostic value of the presence and number of tumor deposits (TDs) and the combination of TDs and number of positive lymph nodes (PLNs) in patients undergoing colorectal cancer (CRC) surgery, and to modify N staging.

Method: The clinical data of 1470 patients with stage I-IV CRC who underwent surgery in Wuhan Union Hospital from February 2014 to May 2018 were collected. The optimal cutoff value for TD + PLNs was obtained using X-tile software, and patients were regrouped accordingly.

Objective: To investigate the prognostic value of preoperative body composition and serum tumor markers (STM) in patients undergoing surgical treatment for colorectal cancer (CRC) and to establish the prognostic score for patients with CRC.

Methods: This study enrolled 365 patients (training set 245, validation set 120) with CRC who underwent surgical resection. The predictive value of various body composition features and STM for determining CRC prognosis were compared.

Despite the notable achievements of programmed death 1 (PD-1) antibodies in treating various cancers, the overall efficacy remains limited in the majority of colorectal cancer (CRC) cases. Metabolism reprogramming of tumors inhibits the tricarboxylic acid (TCA) cycle, leading to down-regulation of fumarate hydratase (FH), which is related to poor prognosis in CRC patients. By establishing a tumor-bearing mouse model of CRC with Fh1 expression deficiency, we confirmed that the therapeutic effect of PD-1 antibodies alone was suboptimal in mice with low Fh1 expression, which was improved by combination with a protein invertase subtilisin/kexin 9 (PCSK9) inhibitor.

Article Synopsis
  • This study investigates how body composition, specifically skeletal muscle and fat levels measured via CT scans, impacts postoperative complications and long-term outcomes in rectal cancer patients after surgery.
  • Researchers analyzed data from 415 patients at Wuhan Union Hospital between 2014 and 2018, using CT images taken within 3 months before surgery to assess muscle and fat indices.
  • Findings show that higher skeletal muscle density and index correlate with better overall survival and disease-free survival, while larger intermuscular fat areas are linked to poorer outcomes, suggesting body composition is crucial for predicting recovery and prognosis in these patients.

Background: Tumour perineural invasion (PNI) is a predictor of poor prognosis, but its effect on the prognosis of patients with colorectal cancer (CRC) has not yet been elucidated.

Methods: This retrospective study used propensity score matching (PSM). The clinical case data of 1470 patients with surgically treated stage I-IV CRC at Wuhan Union Hospital were collected.
