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.
