A current study being run by the RTOG is using 3D conformal treatment and dose escalation to evaluate whether this promising technology can safely deliver higher doses of radiation to the tumor in patients who have had an operation for glioblastoma multiforme. Prior studies have not shown any benefit from higher doses of radiation than is conventionally given over six weeks's time, but it is hoped that modern technology may help limit the dose of radiation to normal brain tissue to a greater extent than was previously possible. If this can be safely done, one outcome may be improved survival from lower failure rates, but this remains to be proven.

Stereotactic body radiotherapy (SBRT) - Stereotactic body radiotherapy or SBRT for lung cancer is a technique in which a high dose of radiation is delivered to a relatively small area of tissue in an attempt to rid the body of cancer. In contrast to other types of radiation therapy, SBRT is sometimes used with a curative intent with lung cancer. For some people with early stage lung cancer that is considered inoperable, SBRT may provide results similar to surgery. SBRT may also be used, at times, for lung cancer which has spread . When only a few metastases from lung cancer are present in the brain or liver, SBRT has on occasion resulted in long-term control of the disease.
