Statistics of soft-tissue sarcoma in Japan: Report from the Bone and Soft Tissue Tumor Registry in Japan

Using the BSTT Registry, this study has clarified the epidemiology, treatment, and prognosis of patients with STSs in Japan. Our experiences with the BSTT Registry will be of help to other countries where aging of the population is occurring. Continuous accumulation of clinical data in the BSTT Registry should provide more informative data on STSs, thus improving both the level of medical care offered by clinicians and the outcomes for patients through sharing of such data and promotion of clinical research.
