Hepatectomy for resectable colorectal liver metastases provides a survival advantage but is usually reserved for patients without extrahepatic disease. Metastases to perihepatic lymph nodes (LN) occur with controversial significance. This study uses standard pathologic analysis and immunohistochemistry (IHC) to determine the impact of occult metastatic disease to perihepatic LN in patients with colorectal cancer undergoing hepatectomy. ⋯ In patients with hepatic colorectal metastases, IHC analysis of perihepatic LN adds prognostic value regarding the timing and burden of recurrence after resection. Routine IHC assessment of perihepatic LN is reasonable since the information garnered would potentially influence postresection chemotherapy recommendations.

To evaluate the outcome of patients with carcinoma of anal margin in terms of recurrence, survival, and radiation toxicity. ⋯ We conclude that definitive RT and/or BT yield a good local control and disease-specific survival comparable with published data. This study suggests that radiation dose over 59.4 Gy seems to increase treatment-related morbidity.

Percutaneous hepatic perfusion (PHP), a regional cancer therapy, entails insertion of percutaneous catheters to isolate hepatic vasculature and enable simultaneous hepatic venous hemofiltration of high-dose chemotherapy. PHP has been shown to be safe and to benefit some patients with liver metastases. ⋯ PHP therapy can be associated with transient but significant hemodynamic and metabolic perturbations. In order to assure patient comfort and facilitate timely diagnosis and treatment of associated hemodynamic and metabolic changes, we favor administration of general anesthesia, rather than sedation, for patients undergoing PHP.

Delayed visceral arterial hemorrhage caused by inflammatory vessel erosion represents a rare but life-threatening complication after pancreatic head resection. Therapeutic options include reoperation or endovascular minimally invasive techniques such as embolization or stent graft placement. The present article describes our experiences with implantation of newly developed low-profile stent grafts. ⋯ Minimally invasive therapy using low-profile stent grafts is an effective and safe procedure for the treatment of delayed visceral arterial hemorrhage following Whipple's procedure. The technique is a promising alternative to standard procedures such as surgical repair or embolization.

Mastectomy rates have been assumed to be a function of physician recommendations, although they correlate with patient involvement in decision making. The influence of age on the decision-making process and treatment choice is poorly described. ⋯ Older women participate equally in breast cancer surgical decision making and are equally likely to select mastectomy, but use less knowledge to make the decision. The impact of education and ethnic origin on mastectomy use indicates the need for improved educational strategies for these groups.
