Article Synopsis
  • Recent advances in understanding the molecular biology of primary colorectal cancer (CRC) have highlighted the role of microsatellite instability (MSI), which is found in about 15% of sporadic cases, but knowledge about colorectal liver metastases (CRLM) is still limited.
  • The study analyzed 51 resected CRLM specimens to assess the incidence of MSI by examining immunohistochemical staining for MLH1 and MSH2, aimeding to improve patient selection for potential curative surgeries.
  • Results showed no abnormal staining for MLH1 or MSH2 in the specimens, indicating a low incidence of MSI in CRLM, suggesting that MSI may not be a reliable marker for clinical decision-making in this context.

Pancreatic neuroendocrine tumours (pNETs) are rare and surgical resection offers the only possibility of cure for localised disease. The role of surgery in the setting of locally advanced and metastatic disease is more controversial. Emerging data suggests that synchronous surgical resection of pancreas and liver may be associated with increased survival.

Background: Pancreatoduodenectomy offers the only chance of cure for patients with periampullary cancers. This, however, is a major undertaking in most patients and is associated with a significant morbidity and mortality. A multidisciplinary approach to the workup and follow-up of patients undergoing pancreatoduodenectomy was initiated at our institution to improve the diagnosis, resection rate, mortality and morbidity.

Background: Although popliteal artery aneurysms (PAA) are rare (0.1% of the general population), they are the most common of the peripheral aneurysms. They are associated with concomitant contralateral PAA and abdominal aortic aneurysm (AAA), with a high risk of complications and an elevated morbidity and mortality.
