• Grade 3/4 toxicities: heme 35%, GI 14%,
pulmonary 23%.
• 43 pts (75%) were evaluable for the primary
endpoint; 36 pts underwent resection. 7 pts had
residual mediastinal dz. 27/43 (63%) achieved
mediastinal clearance.
• There was a 14% (5/37) incidence of grade 3
postoperative pulmonary complications. There
was only one postop grade 5 toxicity (3%).
RTOG 0229, Suntharalingam IJROBP 2012
• With a median follow-up of 24 months for all
patients, the 2-year overall survival rate was 54%,
and the 2-year progression-free survival rate was
33%. The 2 year survival rate was 75% for those
who achieved nodal clearance.

• Only 54-57% of Stage IIIA patients in either arm
underwent a complete resection (R0)
• MST was not different between the arms (15.5
mo. in chemoradiotherapy and 16.8 mo. in
chemotherapy only arm, p=0.97)
• Radiation was delivered in a non standard form
(and we know from RTOG 9410 that BID is
inferior!)
• Pneumonectomy contributed to mortality (14%
versus 6%)

clearance matter?

New technology requires
careful planning
• Treatment planning cannot make up for
drawing the wrong volumes
• The most radioresistant tumor cell is the one
that’s not in the field!

Imaging Questions
Imaging Questions
• When is the tumor within my fields?
– Tumor motion, mostly respiratory
– 4D CT
– Does motion change during Rx?
• Infection
• Response to Rx
• How often should we re-measure motion?
– Who would most benefit?
• How does the tumor change shape during Rx?
– Second-to-second
– Day-to-day
Benefits of Cone Beam CT
Imaging Questions for
Radiation Oncology
– Normal tissue function/risk?
• Interpatient differences
– Radiosensitivity
– Underlying disease
– Pretreatment vs. post treatment imaging
• Can Dose/function histograms be developed?
Should we incorporate
SPECT?
Voxel-by-voxel ventilation
Ventilation
Ventilation
Imaging Questions for
Radiation Oncology
– How do you account for these changes with IMRT or
protons?
– How do doses add together?
– How do we image biology?
• Tumor?
– SUV?
– MR Spectroscopy?
– Hypoxia, other markers?
Take Home Points
• Current standard of care for stage
IIIA/IIIB NSCLC continues to be
defined
• Trimodality is reasonable option on
study and/or with well informed
patients
– Role of surgery should be based
• Nodal Status
• Performance Status
• Surgeon experience
Take Home Points
• Success of trimodality depends on:
– Good radiotherapy techniques
– Good surgical techniques
• Higher doses of radiation preoperatively may improve outcomes
• Imaging will grow in importance in
oncology
