Data on lung cancer from the Radiation Oncology Greater Area Database (ROGAD) was evaluated in this paper. Between the 2nd survey in 1992 and the 8th survey in 1998, 2, 082 cases were accumulated. There were 1, 584 (76%) men, and 498 (24%) women. The most frequent ages were between 60 and 69 (36%), followed by 70 and 79 (27%). The clinical stage 1 was 6%, stage 2, 5%, stage 3, 34%, and stage 4, 54%. The histology was adenocarcinoma in 35.1%, squamous cell carcinoma in 26.4%, small cell carcinoma in 14.3% and large cell carcinoma in 3.3%. The treatment methods were radiation only in 52%, chemoradiotherapy in 31% and post-or pre-operative radiation in 10%. The treatment targets were primary only in 16%, lymh node only in 9%, metastases only in 37%, primary with metastases in 28% and others in 10%. The curative purposes were 24%, semi-curative purposes were 11%, palliative purposes were 37% and symptomatic purpose were 27%. The cumulative survival rate was not accurate because of the difficulty of following-up cases. The one-year, twoyear, three-year and five-year cumulative survival of the cases without metastases would be 86.7-36.8%, 73.6-18.2%, 59.6-11.2% and 40.1-7.0%, respectively. The data deficit rate was 88% in the grade of histology, 17% in T cathegory, 18% in N-category, 12% in M-category, 14% in stage, 11% in primary response, 16% in complications. Considering our data analysis, a new datebase for JASTRO should be created, and methods for building up a more useful database should be discussed.
