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。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。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。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, andtreatment characteristics at the Department of Radiation Oncology, Kaohsiung ChangGung Memorial Hospital between 1987-1996. Some of the survey items were compared withresults of Patterns of Care Study (PCS) in the United States.in a personal computer-based cancer registry system between 1987 and 1996 was reviewedand analyzed. Major items of the survey included: new cases per annum (NCPA), patientreferral, average patient load and its trends over time, disease patterns, treatmentintent, treatment completion, fractionation patterns, and application of computerin the assistance of radiotherapy treatment planning.increased by year, and reached a plateau during the last four years. The crude rateof 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) Theaverage patient load (NCPA per personnel or machine) was as follows: radiationoncologist: 281 (range, 177-339); physicist: 350 (range, 280-466); technologist: 123(range, 86-157); machine: 428 (range, 298-705). The patient load for personnel andmachine declined over time. (3) The five diseases most commonly treated were cancersof 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 (definitiveplus adjuvant). Twelve percent of patients were treated with salvage RT forpost-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 treatmentplanning 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- dimensionalplanning and an increase of three-dimensional planning.decline of average patient load for personnel and machine over time. The rate of cancerpatients referral for radiotherapy was significantly lower than the PCS survey inthe United States. Regarding the treatment, the BID scheme was rarely used throughoutthe period of the survey. The treatment completion rate and percentage of patientstreated with curative intent appeared satisfactory and comparable with the resultof PCS survey.
