Dr. Zhongxing Liao, MD

Dr. Liao's research activities aim to improve the therapeutic ratio of radiotherapy for thoracic malignancies through translational research. Specifically, her efforts focus on personalizing chemoradiotherapy for lung cancer by reducing treatment-related toxicity, and increasing cancer cure rates by using predictive biomarker strategies and advanced radiation delivery technology. She has continued her leadership role in conducting practice-changing clinical trials locally and nationally.  She has led the first prospective randomized trial comparing PSPT and IMRT for locally advanced NSCLC, she is the national PI of RTOG 1308 phase III randomized trial comparing photon and protons, as well as the PI for imagine guided IMRT or IMPT with simultaneously integrated boost and concurrent chemoradiation for NSCLC. 

 Dr. Liao's translational and clinical research activities have been highly productive, as evidenced in her CV by publications in highly respected peer-reviewed scientific journals, by invitations to write review articles, and by invitations to national and international meetings as keynote or panel speakers. She has accumulated rich experience and knowledge, developed leadership skills and effectiveness to conduct critical research projects and corporate trials. Dr. Liao anticipates that her research will continue its success as many completed projects mature with results presented to and accepted by the international scientific community, and ongoing projects progress smoothly.

Dr. Mark Pankuch, MD

Mark Pankuch is currently the Director of Medical Physics at the Northwestern Medicine Chicago Proton Center where he oversees medical physics related operations for the proton center and 4 nearby photon centers within the West and North regions of Northwestern Medicine.  The proton center has been treating patents since 2010, with over 5000 patients treated thus far.  Over the past several years, Dr. Pankuch has given numerous presentations on the topics of Proton Therapy at the local DOE labs, professional meetings, and vendor sponsored educational talks. He currently involved in research projects including funded collaborations in proton imaging.  Dr. Pankuch is currently acting as the co-chair for the physics committee in the multi-institutional PCORI study randomizing protons vs. photon for stage 3 breast cancer.  He also plays an active role in the Proton Collaborative Group and is currently acting as the physics chair. 

The NM Proton Center is one of very few centers that treats a portion of their proton patients in the seated position.  The center has an in-room CT scanner that is capable of acquiring fan beam CT’s in the upright position. This “horizontal plane” scanner enables seated treatments to brain, ocular melanoma and thorax patients.  A dedicated thoracic chair was development specifically for lung and mediastinal treatments. The NM proton center has observed the expected anatomical differences between supine and seated set-ups.  Considerable dosimetric benefits are often obtained in the seated position for lung cancer patients.
