The impact of primary tumor sidedness on survival in early-onset colorectal cancer by stage: A National Veterans Affairs retrospective analysis.

Background: The incidence of early-onset colorectal cancer (EOCRC) is rising. Left-sided colorectal cancer (LCC) is associated with better survival compared to right-sided colon cancer (RCC) in metastatic disease. NCCN guidelines recommend the addition of EGFR inhibitors to KRAS/NRAS WT metastatic CRC originating from the left only.

A Unique Case of Severe Hematochezia: Ruptured Pseudoaneurysm of the Superior Rectal Artery.

Visceral artery aneurysms are rare, with an incidence of 0.01%-2% based on autopsy results. Among the visceral arteries, inferior mesenteric artery aneurysms are the rarest.
