Mark your calendar for the 57th Annual Conference of the Particle Therapy Co-operative Group (PTCOG57) and 5th Annual PTCOG-NA meeting. The 2018 event will take place May 21-26, 2018 at the Duke Energy Convention Center in Cincinnati, Ohio, USA. With the beautiful backdrop of the Ohio River, and dynamic culinary, arts, culture and entertainment scenes, we promise an outstanding experience in the Queen City. We’re excited about our developing particle radiotherapy agenda that will educate and inspire you. We look forward to seeing you in Cincinnati.

Welcome Message from PTCOG 57 Conference Chairs

On behalf of the Organizing Committee, we invite you to attend the 57th Annual Particle Therapy Co-Operative Group (PTCOG) Meeting, taking place Monday, May 21 through Saturday, May 26, 2018, at the Duke Energy Convention Center in Cincinnati, Ohio USA. The conference is held in conjunction with the 5th Annual Meeting of the PTCOG North American chapter and co-hosted by Cincinnati Children’s Hospital Medical Center, the University of Cincinnati and the University of Cincinnati Medical Center.

PTCOG 57 kicks off with the Educational Session from May 21-23. The Educational Session provides a comprehensive overview of physics, technology, radiation biology and medicine as it relates to particle therapy, from its origins to modern technologies and practices. After concluding the Educational Session, the Scientific Session commences, from May 24-26. The Scientific Session includes invited and submitted oral and poster presentations, covering all major sub-topics within particle therapy, including but not limited to medical physics, engineering, biology, medicine, and translational science. The theme of the meeting is: “Translating Science and Technology into Cancer Cures.” In addition to the oral and poster presentation format, special keynote sessions and invited panel discussions are designed to highlight and reinforce the theme of translational research and development.

PTCOG 57 is appropriate for a wide range of disciplines within the field of oncology. Physicians, physicists, biologists, basic scientists, as well as nurses, radiation therapists, dosimetrists, administrators and industry professionals, are cordially invited to attend. Attendees will have the opportunity to tour the state-of-the-art Cincinnati Proton Therapy Center, a collaboration between Cincinnati Children’s Hospital and University of Cincinnati Medical Center. Attendees are also invited to attend a Gala Event at a private space in Great American Ballpark to watch the Cincinnati Reds play the Pittsburgh Pirates, located in Cincinnati’s Banks Entertainment district, steps from all the excitement the Cincinnati waterfront has to offer.

In May, Cincinnati is at her best with a temperate spring climate and greenspaces in full bloom. Set on the banks of the beautiful Ohio River, Cincinnati (also known as “The Queen City”) is a cultural and financial center of the United States mid-west. The conference venue is in the heart of the entertainment district, with multiple opportunities for dining, sporting events, and exploration of the artistic, cultural and educational offerings of the city.

The 57th Annual PTCOG Conference aims to enhance your scientific knowledge in particle therapy, deliver a comprehensive and well-round educational experience, and stimulate the particle therapy community in driving innovation, research and best practices.

We welcome you from around the world to PTCOG 57 and Cincinnati, Ohio.

Welcome from PTCOG Chair

I would like to add my welcome to you in anticipation of seeing you at PTCOG 57 in Cincinnati. As the Chair of PTCOG, it is my honor to let you know that through the hard work of Cincinnati’s Local Organizing Committee and the PTCOG Scientific Program and Educational Subcommittees, PTCOG 57 is shaping up to be a most memorable meeting! Particle Therapy has always been a multi-disciplinary collaboration. It may be one of the shining examples of how science and technology have been seamlessly fused and applied to medical therapy. Therefore, it is appropriate that I repeat the theme of this meeting, which is “Translating Science and Technology into Cancer Cures”. Accessibility to Particle Therapy continues to be in a strong growth phase and the modality has shifted from work in national science laboratories to multi and single room treatment facilities in hospitals and outpatient clinics. Additionally, the focus is shifting from the application of technology to the application of life sciences, such as biology and concurrent medical oncology therapies, to benefit even more patients.

I believe that it’s important to remind you that PTCOG was central to the initial translation of the science and technology of particle therapy to hospital and clinic based particle therapy treatments. Our organization has since evolved to be the heart and soul of the entire Particle Therapy community. As this modality becomes more widespread, its applicability becomes more germane within other organizations. Therefore, PTCOG has taken steps to start to form relationships with organizations such as ESTRO and IPACS to build the bridges necessary for working together. It is so important to ensure that the powerful tool of Particle Therapy is used appropriately and cost effectively. It is for that reason that we have continued to expand the number of PTCOG subcommittees which are actively developing consensus standards for virtually every disease site and this year we have added an opportunity for the community to submit abstracts that will contain elements of cost effectiveness.

The Educational program has also expanded to include outreach sessions which are held in places outside the PTCOG annual meeting. In addition, workshop meetings, again outside of the normal PTCOG annual meeting, are being formed. One such meeting is the Treatment Efficiency Workshop with a focus on quality assurance and treatment planning, being held December 4-6, 2017, in Knoxville Tennessee. More programs will follow.

PTCOG, as an organization, is taking an increased role in the management of the annual meetings and has developed more detailed criteria for hosting future meetings. As attendance at our annual meeting continues to grow, this change will insure that our meetings maintain the high quality, consistency and relevance of past meetings and remain an exceptional value for our sponsors without which our meetings will not be possible. PTCOG is also happy to begin to host an exchange program to help those who may be interested in visiting other particle therapy facilities. In addition, we will soon be starting an open web-based community for discussion and advanced technological and clinical development. All of this is necessary to fulfill the ever increasing appetite for activities associated with today’s Particle Therapy community. This, as indicated earlier, is a multidisciplinary community and involves academia, healthcare and the vendor companies all of whom learn and grow from each other. PTCOG is an acronym for the Particle Therapy Co-Operative Group, and, despite our growth, is more than ever a community whose foundation of success is based on cooperation and interaction. We must rise to the challenge to enable that interaction while embracing the large community and robust annual meetings.

I invite your participation and leadership in the Particle Therapy community and I look forward to seeing you, meeting you and talking with you at the PTCOG 57 annual meeting in Cincinnati, Ohio in May.
