Outcome Measures

Primary Outcomes (1)

  • 3-year local control ratio of the treated lung area

    The primary goal of this study is the 3-year local control rate of pulmonary lesions treated with proton therapy. It is judged that the local control rate is improved when the pulmonary metastases of colorectal cancer using conventional X-ray is assumed to have 3-year local control rate of 60% and the 3-year local control rate of proton therapy is set to 80% or more

    up to 3 years

Secondary Outcomes (2)

  • 3-year survival rate of treated patients

    documented data of death, up to 3 years

  • 3-year disease-free survival rate of treated patients

    documented date of progression or death, up to 3 years

Study Arms (1)

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically diagnosed colon adenocarcinoma in primary or metastatic lesions..
  • If there is no other remote metastasis other than lung, or if there is, control is possible
  • If there are less than 2 lung metastatic lesions
  • If they refuse lung surgery or surgery is inappropriate (medically unsuitable for surgery due to surgery refusal, diabetes mellitus, high blood pressure, pulmonary disease, heart disease, etc., repeated surgery, poor systematic function, short disease-free period, etc.)

You may not qualify if:

  • Other histologic cancer other than adenocarcinoma of the colorectal
  • Colorectal cancer without primary lesion resection
  • If there is another remote metastasis and is not completely resected or regulated
  • If the patient has experience of other invasive cancer diagnosis within 5 years of colorectal cancer diagnosis
  • Pregnancy and women under lactation
