The 15th World Congress of the International Photodynamic Association (IPA) was a joint event with the SPIE Biophotonics South America, the first SPIE event in the south hemisphere.
Photodynamic Therapy and Biophotonics are related topics and this joint conference could bring together scientists with common interests and knowledge. The congress took place on 22-26 May 2015, at the Belmond Copacabana Palace Hotel, Rio de Janeiro, Brazil. This event is part of the celebration of the International Year of Light and Light-Based Technologies (IYL 2015) and had the support from Brazilian Physical Society (SBF).
The IPA is an academic society whose membership consists of the most prominent international scientists and clinicians involved in performing and researching in Photodynamic Therapy (PDT) and Photodiagnosis (PD). It aims to promote the study of treatment and diagnosis using light, to disseminate such information to the members of the IPA, the medical community and to the public. The biennial World Congress therefore plays an important role in the activity of the association and is an excellent way to keep update of the new developments in this rapidly evolving field.
In this 15th World Congress over 200 registered participants from 27 nations (Argentina, Austria, Bolivia, Brazil, Canada, Chile, China, Ecuador, Egypt, Finland, France, Germany, Ireland, Japan, Mexico, Netherlands, Peru, Poland, Portugal, Russia, Singapore, South Korea, Sweden, Swiss, Turkey, United Kingdom, United States) delivered over 180 contributions covering all fields of photodynamic applications and beyond.
Before the official opening ceremony three special tutorials were addressed on 22 May:
- Light-matter interaction for non-physicists by Vanderlei S. Bagnato and Cristina Kurachi;
- Basis of Photochemistry by Katarzyna Matczyszyn;
- Basis of Photobiology and Photomedicine by Michael Hamblin.
The meeting was officially opened on 23 May by Vanderlei S. Bagnato, Tayyaba Hasan, Samy Eljamel, Brian C. Wilson and Robert Liberman.
The opening plenary lecture was addressed by Prof. Brian C. Wilson (U Toronto) and Prof. Tayyaba Hasan (Harvard Medical School) about The Future of PDT/PDD. In addition, a round-table for the real value of PDT/PDD was carried out.
During the other days, over nine IPA plenary lectures were addressed:

- Use of recombinant calreticulin as adjuvant to photodynamic therapy for cancer treatment by Mladen Korbelik (University of British Columbia, Canada);
- From combinatorial chemistry to targeting nano-phototherapeutic agents by Kit S. Lam (University of California Davis Cancer Center, USA);
- Photosensitizers tailored trigger specific mechanisms of programmed cell death can improve Photodynamic Therapy by Maurício Baptista (University of São Paulo, Brazil);
- Aspects of real-time dosimetry control in photodynamic therapy by Stefan Andersson Engels (University of Lund, Sweden);
- New discoveries in antimicrobial photodynamic inactivation by Michael Hamblin (Massachusetts General Hospital, USA).
Regarding SPIE, five plenaries lecture were given:
- Global endoscopy: opportunities and challenges in endoscopic imaging and early cancer detection by Sharmila Anandasabapathy (Baylor College of Medicine, USA);
- Acoustic radiation force optical coherence elastography by Zhongping Chen (Beckman Laser Institute and Medical Clinic, USA);
- Polarized light in optical biopsy: enabling technologies towards tissue characterization and imaging by Igor Meglinski (Univ. of Otago, New Zealand);
- Light and life by Herch Moyses Nussenzveig (UFRJ, Brazil);
- Plasmonic nanosensors and nanoprobes: harnessing the power of photonics for medical diagnostics and therapy by Tuan Vo-Dinh (Fitzpatrick Institute for Photonics, Duke Univ., USA).
The plenary lectures were recorded and are available for anyone to watch at: www.photodynamic.org.
All over 80 individual oral presentations were given on the 11 parallel sessions held throughout this IPA Word Congress and these were hosted by a number of Chairs, to whom the society give thanks to for ensuring that all sessions ran in a timely manner. The 11 parallel sessions were: Combined Techniques, Clinical PDT I and II, Dosimetry, Instrumentation, – Mechanisms of PDT and PD I and II, Microbial control, Modern dentistry, New Photosensitizers and Drug Delivery I and II. As part of the World Congress there were also 100 diverse poster presentations.
At SPIE Biophotonics South America over 100 attendees from 17 countries (Argentina, Brazil, Canada, Colombia, France, Germany, Greece, Japan, Mexico, New Zealand, Pakistan, Poland, Russia Federation, Spain, Switzerland, United Kingdom, United States) participated with 42 oral presentations and 122 poster presentations.
The closing remarks of the congress was addressed by Vanderlei S. Bagnato and Prof. Tayyaba Hasan that emphasized the importance of PDT techniques to solve present health problems of society.
During the meeting, we also hold a first evaluation of Brazilian program to treat skin cancer with PDT, medical doctors and others professionals have exposed their principles. PDT/PDD are today broadening up the possibility of optics for a better life and consequently a better world.
Prof. Tayyaba Hasan acknowledged the presence of all attendees and reinforced the importance of more members to join the IPA. It was also announced the next IPA meeting to be held in Portugal and hosted by Prof. Luis G. Arnaut (University of Coimbra).
The local committee was composed by: Vanderlei S. Bagnato (Congress President of the IPA 2015), Cristina Kurachi, Lilian T. Moriyama, Natalia M. Inada, Sebastião Pratavieira (São Carlos Institute of Physics, University of São Paulo). The local committee acknowledge all attendees and the staff for a smooth and pleasure congress. The committee also gratefully acknowledges the support provided by Brazilian Funding Agencies: Capes, CNPq and BNDES.
There is a special section of the Photodiagnosis and Photodynamic Therapy Journal with all abstracts of the Congress available for anyone who would like to know more details of the content of this meeting.
Vanderlei Salvador Bagnato completed his doctorate in Physics at Massachusetts Institute of Technology. Currently he is professor at the University of São Paulo. He has published 368 articles in professional journals, 18 book chapters and 5 books. He also has supervised directed 25 doctoral theses in the areas of Physics, Dentistry and Medicine.
