[Patient and Public Involvement for Cancer Treatments-Physicians' Perspectives]

Patient participation is defined as incorporation of opinions by patients and citizens when clinical trials are planning. It has been early established in the USA and the UK. The Japan Clinical Oncology Group(JCOG)has recently launched a subcommittee of patient participation and has tried to input opinions of patients and citizens in clinical trials. We, Hepatobiliary and Pancreatic Oncology Group in JCOG, has held 3 meetings of patient participation for 3 years. We introduced our policy and clinical trials and discussed off-label drugs or treatments. In the third meeting in 2019, we have discussed precision medicine using genome analysis and clinical trials which are currently planning in our group. There are some significances and expectations to patient participation from the points of views of researchers. It is meaning to pick up clinicalunmet medicalneeds from patient participation and input requests and opinions of patients to a protocol. Opinions of patients and citizens may be useful to make informed consent form easy to read and understand for patients and their family. In order to accelerate recruitment of patients in clinical trials, it is important that patients and citizens understand exactly clinical trials through patient participation. Patient participation has just begun in Japan. It is expected to establish Japanese patient participation in the near future. It is important for not only researchers but also patients to obtain some benefits from patient participation.
