子宮頸癌非手術(根治的放射線治療)症例におけるPatterns of Care Study (PCS)95-97,99-01調査の比較からみるevidenceの臨床への浸透

摘要

To establish national patterns of practice for uterine cervical cancer treated with radiotherapy, the records of 1995-1997 and 1999-2001 were corrected. We compared two surveys to evaluate whether the evidence supported by the literatures reflected the process of clinical practice in our country. A beam energy of > = 10 MV was used for 71.9% in A and 44.8% in B in 95-97 JPCS survey, while 76.1% in A and 69.7 % in B in 99-01 JPCS (p<0. 0001). Intracavitary brachytherapy was chiefly underwent using high-dose-rate source. Concurrent use of chemotherapy increased significantly between two surveys (p < 0. 0001).The JPCS established the Japanese national practice patterns of care for uterine cervical cancer patients treated with radiotherapy.
