摘要

     目的:調查高雄長庚醫院放射腫瘤科1987至1996十年期間之人力需求、病患、 及治療特徵。部分項目和美國的Patterns of Care Study(PCS)做比較。 材料與方法:自1987至1996存放在個人電腦癌登系統的資料檔案進行回顧性的分析。 主要項目包括:每年新病人數、癌患轉診、各工作人員及治療機的平均負荷、疾病型態、治 療完成率、分次方式、治療目的、及電腦治療計劃的使用情形。 結果:(1)每年新病人數從458-1265人(平均1087),數目呈逐年緩和上升,但近4年則 呈水平狀態。癌患轉介率約30%,此轉介率在前期(1987-1991)為26%,後期(1992-1996)為 33%,呈微幅成長,但整體而言,仍比PCS的報告為低。(2)各工作人員及治療機的平均負荷 (病人數/年)如下:醫師281(177-339),物理師350(280-466),技術師123(86-157),治療 機428(298-705),各工作人員及治療機的平均負荷呈逐年下降的趨勢。(3)最常接受放射治 療的五種癌病依次是:肺癌(15.9%)、子宮頸癌(14.5%)、鼻咽癌(13.1%)、頭頸部腫瘤(12.2%)、 及直腸癌(7.2%)。單純良性疾病接受放射治療則佔1%。(4)1至15歲小兒腫瘤佔1.8%。(5)57% 的病患其治療目的是治愈性,12%的病患因手術後復發而接受放射治療。(6)整體的治療完成 率為76%。(7)使用傳統的分次方式佔69%,一天兩次的分次佔1%,並且大部分是頭頸部腫 瘤。(8)使用電腦做治療計劃則呈逐年激增的趨勢,3D的治療在最近一年已超越2D的治療 總數。 結論:各工作人員及治療機的平均負荷有逐年降低的趨勢,這個趨勢和PCS類似。本院 的癌患轉診接受放射治療的比例偏低,這種現像在十年期間並未有太大的改善。一天兩次的 治療在整個調查期間極少使用。治療完成率及以治癒為目標的比例,則大致令人滿意並且和 PCS相近。
     Purpose To conduct a survey on the institutional manpower, patients, and treatment characteristics at the Department of Radiation Oncology, Kaohsiung Chang Gung Memorial Hospital between 1987-1996. Some of the survey items were compared with results of Patterns of Care Study (PCS) in the United States. Methods and Materials: The database of 9785 radiotherapy (RT) patients registered in a personal computer-based cancer registry system between 1987 and 1996 was reviewed and analyzed. Major items of the survey included: new cases per annum (NCPA), patient referral, average patient load and its trends over time, disease patterns, treatment intent, treatment completion, fractionation patterns, and application of computer in the assistance of radiotherapy treatment planning. Results: (1) The NCPA ranged from 458 to 1264, the mean being 1087. The number increased by year, and reached a plateau during the last four years. The crude rate of patient referral for RT was 30%. The referral rate in the two treatment periods, 1987-1991 and 1992-1996, increased mildly from 26% to 33%, respectively. (2) The average patient load (NCPA per personnel or machine) was as follows: radiation oncologist: 281 (range, 177-339); physicist: 350 (range, 280-466); technologist: 123 (range, 86-157); machine: 428 (range, 298-705). The patient load for personnel and machine declined over time. (3) The five diseases most commonly treated were cancers of the lung (15.9%), cervix (14.5%), nasopharynx (13.1%, NPC), head/neck (12.2%, exclude NPC), recto-sigmoid (7.2%). Purely benign disorders accounted for about 1% of cases. (4) Pediatric patients of age ≦ 15 years accounted for 1 .8% of cases. (5) Fifty-seven percent of patients were treated with curative-intent (definitive plus adjuvant). Twelve percent of patients were treated with salvage RT for post-surgical recurrence. (6) The overall treatment completion rate was 76%. (7) Conventional fraction, 1.8-2 Gy/day, was used in 69% of patients. Twice-a-day (BID) scheme accounted for 1% of cases. (8) The application of computerized treatment planning increased by sixfold in the two treatment periods, 1987-1992 and 1992-1996, respectively. There was an obvious trend toward a decreased use of two- dimensional planning and an increase of three-dimensional planning. Conclusion: Compared with the PCS survey, there was a similar trend toward a decline of average patient load for personnel and machine over time. The rate of cancer patients referral for radiotherapy was significantly lower than the PCS survey in the United States. Regarding the treatment, the BID scheme was rarely used throughout the period of the survey. The treatment completion rate and percentage of patients treated with curative intent appeared satisfactory and comparable with the result of PCS survey.
