140
What is the study design in the IMPRINT ph III trial in epithelioid or biphasic malignant pleural mesothelioma stage I-IIIA
pleurodectomy/decortication and pemetrexed+platinum

INT 0139/RTOG 9309
142
Describe the study set-up of the PET-PLAN study.
RT to PET FDG avid sites and 50 Gy ENI
vs
RT to PET FDG avid sites only
60-74 Gy as high as feasible, concurrent chemo.

14.6 months vs 17 months vs 15.6 months

153
Describe methods of NRG/RTOG 0937.
Patients with ES-SCLC, 1-4 metastatic lesions and no brain metastases after CR/PR from 4-6 cycles platinum chemo
PCI 25 Gy only
vs
PCI and consolidative RT to thorax and original sites of mets

154
What were the results of the NRG/RTOG 0937 trial investigating consolidative RT to thorax and mets in ES-SCLC?
Consolidative RT to thorax and extracranial metastases delayed progression but did not improve 1-year OS.
The trial was closed early due to futility.
155
