Is it safe and appropriate to palliatively treat abdominal or thoracic tumors with concurrent chemotherapy when using fractions of 250-300 cGy?
For example, there is a retrospective series out of MD Anderson (Kim, Acta Oncologica 2008) wherein 37 patients with gastric cancer were treated with palliative RT (median dose 35 Gy in 14 fractions) with most patients having received concurrent chemo. Are there any agents that must be avoided with palliative RT?

I have routinely given 250cGy per fraction to total doses of 3500-3750cGy with single-agent radiosensitizing chemotherapy (usually 5-FU or capecitabine) without apparent significant toxicity, though we have not reviewed our data. So I generally consider this to be a safe regimen and consider it for ...
