What fractionation do you use for consolidative chest RT in extensive stage SCLC?

This is a well-tolerated schedule with respect to esophagitis. For those ...

The ED SCLC TRT is used sequentially in responders with residual chest disease and good performance status. In the CREST trial 30 Gy in 10 is a fine TRT for ED SCLC standard. Also, the RTOG chest plus isolated fewer than 3 distant sites study selected 45Gy in 15fx...a scheme that was tolerable, and ...
