Experts, might someone recommend nexavar (sorafenib) for a stage 4 inactive neuroendocrine pancreatic cancer patient?

Possibly: Stage 4 indicates that you have net at a site distant from the pancreas or regional lymph node, likely the liver. Not clear what you mean by"inactive", whether you mean it is stable or not secreting any substance. In any case, sorafenib (nexavar) is being tested in metastatic net in clinical trials (http://clinicaltrials.Gov/ct2/show/nct00131911) & (http://www.Ncbi.Nlm.Nih.Gov/pubmed/23475104).

Maybe: The treatment of metastatic neuroendocrine carcinoma varies widely and depends on several factors, including tumor grade, pattern of spread, and pace of growth. Drugs like Nexavar (sorafenib) are used, but not as front line treatment. Systemic therapy is used when the disease is not limited to an area that would be amendable to local treatment (i.e. Liver).
