A preoperative nomogram to predict surgical site infection (SSI) in colorectal cancer (CRC) patients was developed and validated using data from 1,445 patients. Seven key predictors were identified, yielding strong calibration and discrimination. The model achieved an area under the curve (AUC) of 0.838 in training and 0.793 in validation cohorts, demonstrating greater predictive benefit […]

High neutrophil-to-lymphocyte ratios indicate poor cancer outcomes
In a study involving 2,742 stage III colorectal cancer patients, high neutrophil-to-lymphocyte ratios (NLR) both before and after surgery were linked to significantly worse disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS). Specifically, patients with consistently high NLR levels faced a 30% increased risk of worse DFS and a 36% increased risk of […]
Nomogram developed to predict severe abdominal adhesions before surgery
A novel nomogram was developed to predict severe intra-abdominal adhesions prior to definitive surgery for anastomotic fistula post-small intestine resection. Analyzing data from 414 patients, five key predictors emerged: SOFA score, early-stage abdominal infection duration, preoperative albumin levels, fat area ratio, and preoperative C-reactive protein levels. The nomogram achieved a concordance index of 0.80 in […]
Pelvic inlet closure reduces postoperative ileus in surgery patients
Closure of the pelvic inlet with a bladder peritoneal flap during abdominoperineal resection significantly decreased the rate of postoperative ileus due to incarceration, showing a rate of 0% versus 17% in those without closure (p=0.03). Additionally, patients with pelvic inlet closure experienced a shorter hospital stay, averaging 6.74 days compared to 9.00 days in the […]
New guidelines offer personalized strategies for rectal adenocarcinoma
French intergroup clinical practice guidelines for managing rectal adenocarcinoma were published in September 2023. The guidelines categorize treatment based on tumor stage, with specific recommendations for endoscopic and surgical excision, radical surgery, and total neoadjuvant treatment. Additionally, they emphasize rectal conservation for select small tumors responding well to previous therapies. Immunotherapy is highlighted for certain […]
Fusion model predicts KRAS mutations in rectal cancer effectively
A study evaluated deep learning, radiomics, and fusion models to predict KRAS mutations in rectal cancer using endorectal ultrasound images from 304 patients. Among the models, the feature-based fusion model (dlrexpand10_fb) achieved the highest area under the receiver operating characteristic curve (AUC) of 0.896, indicating superior predictive performance. Additionally, incorporating peritumoral regions significantly improved the […]
Treatment at accredited hospitals improves outcomes for colon cancer patients
A retrospective study involving 222,583 colon cancer patients highlights the impact of Commission on Cancer (CoC) hospital accreditation on treatment quality and survival. At CoC-accredited facilities, 91.2% of patients received guideline-concordant lymphadenectomy and 81.9% received appropriate chemotherapy. Notably, risk-adjusted mortality rates were significantly reduced across all stages of disease. The findings underscore the importance of […]
Predictive risk score effectively detects lymphovascular invasion in rectal cancer
A predictive risk score (PRS) for lymphovascular invasion (LVI) in rectal cancer has been successfully developed, highlighting key independent predictors. Out of 55,178 patients analyzed, LVI was present in 18.9%. The PRS demonstrated an incidence of LVI of 16.3% in the low-risk group, rising to 40.5% in the high-risk group, indicating its strong predictive capabilities. […]
Single-port robotic surgery shows promise for rectal cancer
An international registry of 104 rectal cancer surgeries using single port robotic technology reported successful outcomes. The procedure demonstrated a 97.1% completeness in total mesorectal excision specimens and a low R1 margin rate of 3.8%. Operating time averaged 168 minutes with no intraoperative complications and a conversion rate of just 1.9%. With a total of […]
Triplet induction chemotherapy shows high response in rectal cancer
The study demonstrated that triplet induction chemotherapy with folfirinox results in an objective response rate of 80% and a disease control rate of 92% in patients with synchronous metastatic rectal cancer (smrc). Analysis of 146 patients revealed that 69% of those with resectable metastases underwent rectal surgery after treatment. Moreover, survival outcomes were notable, with […]
