CT-derived extracellular volume fraction (ct-ecv) significantly correlates with histological grading in colorectal cancer. In a study of 200 patients, ct-ecv, alongside serological markers like CEA and NLR, effectively predicted poorly differentiated tumors. The combination of ct-ecv with NLR and tumor markers yielded an impressive AUC…

Hemorrhoidal disease impacts 10 million Americans, causing bleeding, pain, and discomfort. First-line treatments like increased fiber and water intake, along with phlebotonics, often fail, leading to 80% symptom recurrence. Office-based interventions are vital for grades I to III; rubber band ligation offers 89% short-term relief,…

Postcolonoscopy colorectal cancers (pccrcs) show higher rates of microsatellite instability, CIMP, and BRAF mutations compared to sporadic cases, alongside a greater presence of proximal lesions. Although 5-year survival rates are similar between pccrcs and sporadic colorectal cancers, pccrcs fare significantly worse than cancers detected via…
Cytoreductive Surgery & Peritoneum27 Aug 2025
Cytoreductive surgery markedly improves overall survival in colorectal peritoneal metastasis compared to modern systemic therapies alone. A systematic review of 3316 patients reveals a pooled hazard ratio of 0.447, indicating nearly a 55% reduction in the risk of death. This benefit persists across various palliative…

Intersphincteric resection (ISR) improved five-year overall survival in ultra-low rectal cancer (ULRC) by 6.7% compared to traditional abdominoperineal resection (APR), achieving an 80.8% survival rate. Over a median follow-up of 47.2 months, ISR demonstrated similar surgical complications and hospital stays as APR, solidifying its role…

In a post-hoc analysis of the LASRE trial involving 914 low rectal cancer patients, 74.9% achieved a "textbook outcome," with laparoscopic surgery slightly outperforming open procedures (76.7% vs. 71.2%). Key predictors of failure included a BMI over 24 kg/m². Achieving this ideal outcome correlates with…

Robotic left-sided colectomy significantly outperformed laparoscopic techniques by reducing anastomotic leakage rates by 42% and severe leaks by 51%. These procedures also offered improved lymph node yields (28 vs. 24) and 5-year survival rates (78.2% vs. 74.5%). While upfront costs are higher, robotic surgery saves…

A watch-and-wait strategy may enhance organ preservation in rectal cancer, but local excision (LE) poses significant risks. In a study of 103 patients, those undergoing salvage total mesorectal excision (TME) after local regrowth exhibited superior oncological outcomes compared to LE, which increased recurrence and led…

A novel recurrence risk model (rpv) effectively identifies stage II colon cancer patients who will benefit from adjuvant chemotherapy (AC). Analysis of cohorts from the U.S., Japan, Denmark, and Jordan reveals that high-risk patients achieving higher five-year recurrence-free survival (RFS) rates with AC—76.2% in cohort…

Neoadjuvant immune checkpoint inhibitors boost pathological complete response rates in locally advanced rectal cancer, ranging from 25-62.5%. The clinical complete response rates also soared—hitting 100% in some cases of dMMR/MSI-H tumors. Sphincter preservation rates reached up to 100%. Despite promising outcomes, the evidence stems from…
