Although we usually report 5-year cancer survival using population-based cancer registry data, nowadays many cancer patients survive longer and need to be followed-up for more than 5 years. Long-term cancer survival figures are scarce in Japan. Here we report 10-year cancer survival and conditional survival using an established statistical approach.

We analyzed the trends in the age-standardized incidence rates of 10,460 cases of primary intracranial tumors diagnosed during 1975 and 2004, Osaka, Japan using the Joinpoint regression analysis. During the period 1975-2004, the age-standardized incidence rates of total intracranial tumors increased until 1987 at 3.1% per year and then decreased significantly at -1.

We utilized data from the Osaka Cancer Registry for investigating correlations between hospital volume and 10-year survival of breast cancer patients. According to the total number of surgical procedures of breast cancer in each hospital during the period 1985-1991, we classified reporting hospitals in Osaka into four categories (high, medium, low, very low).

Using data from the Osaka Cancer Registry (OCR), we performed survival analyses on 28,608 patients aged 35-79 years old who underwent surgery for stomach cancer, according to the extent of disease at diagnosis (localized: cancer is confined to the original organ; regional: cancer spreads to regional lymph nodes; adjacent: cancer infiltrates to adjacent tissue; distant: cancer metastasizes to distant organs). The study was divided into four periods; 1975-79, 1980-84, 1985-89 and 1990-94, according to year of diagnosis.
