About JGOS

The JGOS is a multidisciplinary voluntary group aiming to provide “appropriate medical care and treatment to older adults with cancer” at any facility. This organization helps by collecting necessary information on cancer care and treatment for older adults with cancer, and by disseminating its rational interpretation. Through these activities, JGOS hopes to support older adults with cancer to live with cancer by improving their quality of life.
Geriatric oncology focuses on older adults with cancer. This is a relatively new specialty even in the world and is still not well known in Japan. Currently, many researchers and clinicians around the world are working on developing this field. Also, they have established several groups for geriatric oncology mainly in Europe and the United States. In Japan, however, no group collected necessary information on geriatric oncology, making it difficult for healthcare providers to obtain the necessary information for their practice. For appropriate care and treatment of older adults with cancer, knowledge of geriatrics, as well as oncology, is needed. Additionally, collaboration should be done not only with oncologists and geriatricians, but also with nurses, pharmacists, nutritionists, physical therapists, occupational therapists, medical social workers, and other multidisciplinary professionals. We hope to provide accurate information on geriatric oncology and support older adults with cancer to live with cancer.

Basic principles

The basic principles of our group are as follows:

  1. To collect information on geriatric oncology and present it on our website
  2. To collect information not only on oncology but also on geriatrics
  3. To select scientific and reliable information from those of varying quality (Please note that some degree of bias is inevitable)
  4. To distinguish between “fact: information based on scientific evidence” and “opinion: information about recommendations and opinions of experts and academic societies.” (Please note that some degree of bias is inevitable)
    Facts will be presented as “information” and opinions as “recommendations/opinions.”
  5. To present “recommendations/opinions” after thorough discussion among multidisciplinary members of our group based on scientific evidence

About the Logo of the Japan Geriatric Oncology Society.
The logo, combining the “G” in “Geriatric” and “O” in “Oncology”, constitutes a “cane” to help older patients walk on their own. The color of the cane is persimmon, representing our will to help and support older patients. We hope that the information on this site will be helpful to you.
