About ISOO



The purpose of the International Society of Oral Oncology (ISOO) is to promote scientific exchange among health care professionals in oncology about cytotoxic therapy and its impact on the oral environment (including tissues, health and function). The Society provides a multidisciplinary forum for scientists and clinicians to focus on the following areas:

  • Concepts associated with oral consequences of antineoplastic therapy
  • Novel strategies germane to cancer research 
  • Educational pursuits related to cancer and oral morbidity associated with cancer therapy
  • Scientific diversity through collaboration

Important Actions

When the Society was first started, in 1984, it was under the name of The Society for Clinical and Experimental Oral Oncology. The name was changed to The Society for Oral Oncology in 1985 and to The International Society for Oral Oncology in 1992. The name of the Society was changed in 2006 to The International Society of Oral Oncology. The alliance with the Multinational Association of Supportive Care in Cancer (MASCC )was formally implemented in 1998. The alliance was formally renewed in 2008.

Study Groups

 ISOO Oral Care Study Group's goal is to enhance the knowledge of oral complications from cancer therapies and improve clinical management for patients. A major effort includes multiple systematic reviews of the incidence/prevalence, management guidelines, QOL and economic impact of oral complications from cancer therapy. The Oral Care Study Group serves as a resource for collaborative research efforts for members of the group as well as other members of MASCC and ISOO. ISOO Oral Care Study Group was chaired by Fred Spijkervet since 1998 and co-chaired by Mike Brennan since 2004. Siri Beier-Jensen joined as a co-chair in 2010.

MASCC Mucositis Study Group has many ISOO participants. Its major goal is to improve outcomes of patients experiencing oral and gastrointestinal mucosit is associated with anti cancer therapies. The objectives are to influence the design and conduct of clinical investigations, disseminate up-to-date educational information, and serve as a resource for investigators. A major effort of the Mucositis Study group has been a comprehensive review of the literature related to mucositis and development of evidence-based clinical management guidelines. The Mucositis Study Group was chaired by Edward Rubenstein 1998-2004, Dorothy Keefe 2004-2008 and Rajesh Lalla from 2008. Study group co-chair was Mark Schubert 1998-2007. Since 2008 the study group is co-chaired by Joanne Bowen and Sharon Elad.

Member Initiatives

MASCC/ISOO conferences are good meeting places and a basis for cooperation between members, centers, countries and continents. Several collaborative projects have been launched through this annual meeting.
