Acetone compression improves lymph node yield and metastasis detection in colorectal cancer.

Lymph node status is one of the most important prognostic factors in colorectal cancer, and accurate pathological nodal staging and detection of lymph node metastases is crucial for determination of post-operative management. Current guidelines, including the TNM staging system and European Society for Medical Oncology (ESMO) guidelines, recommend examination of at least 12 lymph nodes. However, identification of an adequate number of lymph nodes can be challenging, especially in the setting of neoadjuvant treatment, which may reduce nodal size.

Acute Fatal Liver Toxicity under Erlotinib.

We describe the case of a never-smoker who received second-line erlotinib as a treatment for his non-small cell lung cancer. Within one month, acute hepatic failure developed as well as a thrombotic-thrombocytopenic microangiopathy, with fatal outcome. In patients with non-small cell lung cancer, hepatic toxicity of erlotinib is a rare but severe complication; so far three fatal cases have been reported.
