To examine whether the Patterns of Care Study (PCS) reflects the data for the major areas in Japan, the consistency of variables in the PCS and in the major area database of the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) were compared.
Patients with esophageal or uterine cervical cancer were sampled from the PCS and JASTRO databases. From the JASTRO database, 147 patients with esophageal cancer and 95 patients with uterine cervical cancer were selected according to the eligibility criteria for the PCS. From the PCS, 455 esophageal and 432 uterine cervical cancer patients were surveyed. Six items for esophageal cancer and five items for uterine cervical cancer were selected for a comparative analysis of PCS and JASTRO databases.
Esophageal cancer: Age (p=.0777), combination of radiation and surgery (p=.2136), and energy of the external beam (p=.6400) were consistent for PCS and JASTRO. However, the dose of the external beam for the non-surgery group showed inconsistency (p=.0467). Uterine cervical cancer: Age (p=.6301) and clinical stage (p=.8555) were consistent for the two sets of data. However, the energy of the external beam (p<.0001), dose rate of brachytherapy (p<.0001), and brachytherapy utilization by clinical stage (p<.0001) showed inconsistencies.
It appears possible that the JASTRO major area database could not account for all patients' backgrounds and factors and that both surveys might have an imbalance in the stratification of institutions including differences in equipment and staffing patterns.
为研究“护理模式研究（PCS）”是否反映了日本主要地区的数据，对PCS与日本放射治疗与肿瘤学会（JASTRO）主要地区数据库中的变量一致性进行了比较。
从PCS和JASTRO数据库中抽取食管癌或子宫颈癌患者。从JASTRO数据库中，根据PCS的纳入标准选取了147例食管癌患者和95例子宫颈癌患者。从PCS中，调查了455例食管癌患者和432例子宫颈癌患者。选取了食管癌的6项指标和子宫颈癌的5项指标，对PCS和JASTRO数据库进行比较分析。
食管癌：PCS与JASTRO在年龄（p = 0.0777）、放疗与手术联合应用（p = 0.2136）以及外照射能量（p = 0.6400）方面具有一致性。然而，非手术组的外照射剂量显示不一致（p = 0.0467）。子宫颈癌：两组数据在年龄（p = 0.6301）和临床分期（p = 0.8555）方面具有一致性。然而，外照射能量（p < 0.0001）、近距离放疗剂量率（p < 0.0001）以及不同临床分期的近距离放疗使用率（p < 0.0001）显示不一致。
JASTRO主要地区数据库似乎无法涵盖所有患者的背景和因素，而且两项调查在机构分层方面可能都存在不均衡，包括设备和人员配置模式的差异。
