American Joint Committee on Cancer (AJCC) 7판의병기 I 은 18명, IIA는 8명, IIB는 17명이었으며, T1c는 9명, T2a는 18명, T2b는 4명, T2c는 12명이었다. 본연구에서는 T1-T2a, Gleason score 6점이하, PSA 1 ng/ml 미만의조건을모두충족시킬경우를저위험군 (group 1) 으로정의하였으며, T2b-T2c, Gleason score 7점, PSA 1 2 ng/ml 중한가지이상의조건을충족시키는경우를중간위험군 (group 2) 으로정의하였고, T3a 이상, Gleason score 8 1 점, PSA>2 ng/ml 중한가지이상의조건을충족시키는경우를고위험군 (group 3) 으로정의하였다. 저위험군은 18 명이었고, 중간위험군은 19명, 고위험군은 6명이었다 (Table 1). American Association of Physicists in Medicine Task Group 43에따라전립선임상표적체적에 145 Gy를처방하였다. Mick Applicator (Mick Radio-Nuclear Instruments, Mount Vernon, WA, USA) 를사용하여경직장초음파와 C-arm 유도하에 Best Medical (Springfield, VA, USA) 의 iodine 125 ( 125 I) seed를삽입하였다. 수술실에서경직장초음파를이용하여 5 mm 간격으로전립선이미지를획득하였으며, 초음파이미지에전립선을그려서임상표적체적을정하고이에적절한선량분포를얻기위해필요한 seed 삽입위치와개수를정하기위한전계획을시행하였다. 전계획을바탕으로 seed 삽입을진행하였으며시술중실시간으로 Strata Suite Volume Plan (Rosses Medical Systems, Columbia, MD, USA) 을이용하여등선량곡선과선량체적히스토그람을확인하면서 seed 삽입위치와개수를수정, 보완하였다 (Fig. 1A). Seed 삽입이종료된후방광경검사를통해요도나방광내에 seed가존재하는지여부를확인하였다. Seed 삽입후 1개월후부터부작용을조사하였고, 3개월에서 5 개월간격으로 PSA를추적관찰하였다. 사용된 seed의개수는평균 15개 (79 147) 이었고, seed 의강도는평균.338 mci ( ) 이었으며사용된 needle의개수는평균 3.33개 (19 49) 이었다. Seed 삽입후 1개월가량경과후골반 CT를시행하였고, Strata Suite CT Plan (Rosses Medical Systems Columbia, MD, USA) 프로그램을이용하여 CT 영상에전립선과직장을그린후 (Fig
3 박혜리외 6 인 : 국소전립선암의영구적근접치료 : 조기결과 1B) 삽입된 seed 위치및강도를지정하여임상표적체적과손상위험장기의선량체적히스토그람을알아보았다. 임상표적체적은 CT 영상에서확인되는전립선체적을확장시키지않고사용하였으며, 직장부피는 S자결장이끝나는부위부터직장항문경계부까지외벽을그려서계산한부피와 Crook 등 8) 이손상위험장기의규정과선량측정에관한 American Brachytherapy Society Consensus Statement 에서권고한내용을바탕으로 seed가있는부위에한정하여외벽과내벽을그려서계산한직장벽의부피두가지에대하여선량체적히스토그람을각각분석하였다. 조영증강및도뇨관삽입을하지않은 CT 영상에서요도를정확히구분하기어려우므로요도선량에대한분석은시행하지않았다. 모든환자가호르몬치료를시행받았으며근접치료전에시작한사람이 37명, 영구적근접치료후시작한사람이 6명이었다. 호르몬치료기간이 6개월미만인환자는 4 명, 6개월이상인환자는 3명이었다 (Table 1). 근접치료시행후호르몬치료를한달이상지속한경우는 14명이었고최장기간이 7개월이었다. 방사선치료후생화학적재발의기준으로 Radiation Therapy Oncology Group (RTOG)-American Society for Therapeutic Radiology and Oncology (ASTRO) Phoenix Consensus Conference 9) 에서는외부방사선치료후최저 PSA 값에서 2이상증가한것으로정하였으며 Kuban 등 1) 은 2,693명의근 접치료를시행받은환자를대상으로연구하였을때외부방사선치료와같이최저 PSA 값에서 2 ng/ml 이상증가한것을생화학적재발의기준으로삼는것이추적관찰중치료실패를가장잘반영하였다고보고하였다. 이를바탕으로본연구에서도최저 PSA 값에서 2 ng/ml 이상증가한것을생화학적재발의기준으로정하였다. 또한 PSA 반등 (bounce) 은치료후 PSA가최소값으로감소한후에.1 ng/ml 이상증가하였다가추가적인치료없이추후시행한검사에서감소한경우로정하였다. 생화학적재발률과직장및요로계부작용에영향을미치는요인에대해 SPSS ver. 19. (SPSS Inc., Chicago, IL, USA) 을사용하여독립표본 T 검정및분산분석, 교차분석을시행하였다. 결과근접치료후 1개월에비조영증강골반 CT를시행하여전립선선량분포를분석한결과평균 D 9 ( 전립선의 9% 부피에조사되는최소선량 ) 은 Gy ( ), 평균 D 1 은 Gy ( ), 평균 V 9 ( 처방선량의 9% 이상이조사되는전립선의부피의비율 ) 은 99.7% (96.6 1), 평균 V 1 은 99.2% (94.4 1), 평균 V 15 은 92.4% (69.8 1), 평균 V 2 은 78.1% ( ) 이었다 (Table 2).

4 추적관찰중에.1 이상 PSA 반등이있었던환자는 2 명이었고, PSA가 2 ng/ml 이상증가하여생화학적재발로판정한경우는 2예였으며, 저위험군과중간위험군에서각각 1예씩있었고원격전이가나타난경우는없었다 (Table 3). PSA 증가까지기간은각각 22개월, 29개월이었으며 1 예는영상검사에서재발부위가발견되지않았고, 1예는자기공명영상에서폐쇄공임파선및대퇴부임파선이커진소견이관찰되었으나양전자방출단층촬영술상에서는 18 F fluorodeoxyglucose (FDG) 섭취증가소견은없었다. 임파선크기증가가있었던환자는호르몬치료를추가시행하였으나 PSA가증가된상태로추적관찰중이며, 재발부위가발견되지않았던환자는호르몬치료와전립선고주파열치료를시행한후 PSA가감소하고있다. 생화학적재발과연관된인자를분석하였을때통계적으로유의한인자는없었으며전립선선량분포와 PSA, Gleason score, 위험군, 병기등은모두유의한영향을미치지못하였다. RTOG grade 1의급성직장부작용을나타낸사람이 5명 ( 저위험군 1명, 중간위험군 3명, 고위험군 1명 ) 으로배변시통증이나배변횟수증가등의증상이있었으며 RTOG grade 2 이상의급성직장부작용이나타난경우는없었다. RTOG grade 1의만성직장부작용이 5명 ( 저위험군 4명, 중 Table 2.

Dosoretz 등 14) 은 73세이상의환자군에서는근접치료단독군보다호르몬치료병행군에서사망률이더높았다고보고하고있다. 반면 D Amico 등 15) 은고위험군환자를대상으로근접치료를단독시행하였을경우와근접치료에호르몬치료나외부방사선치료중한가지또는두가지모두를병행하였을경우에서의사망률을비교한연구에서세가지치료방법을모두사용한경우근접치료단독치료에비해유의한사망률의감소를가지고왔다고보고하였으며, Hoffman 등 16) 도고령의고위험군환자에서근접치료단독군보다근접치료, 외부방사선치료, 호르몬치료를모두병행한환자군의사망률이유의하게낮았다고보고하였다. 국소전립선암의적절한치료방법에대해서는환자의상태나연구에따라다양한결과들이보고되고있으며, 중간위험군과고위험군환자에서근접치료단독치료의역할은아직명확하게밝혀지지않았다. 17) 본원에서는저위험군환자뿐아니라중간위험군과고위험군환자중에서도외부방사선치료를거부하거나고위험군의조건중한가지만을충족시키는경우근접치료와호르몬치료를병행하였으며단기간추적관찰결과 4.7% 의낮은생화학적재발률을보였다. 그러나현재최소추적관찰기간이 2년에불과하므로추후장기추적관찰이필요하다고생각한다. 미국근접치료협회 (American Brachytherapy Society, ABS) 의근접치료선량에대한권고안에서는근접치료후시행한선량측정에서 D 9 이처방선량이상이되는것을적절한삽입을판단하는척도로제시하고있으며, 18) 근접치료후시행한 CT로측정한 D 9<14 Gy일때 PSA 제어율은 68% 이며 D 9 14 Gy일경우 92% 이라고보고하였다. 19) Chauveinc 등 2) 은 45명의환자를대상으로조사하였을때시술중초음파로측정한 D 9 이 175 Gy 이상, V 1 이 99.95% 이상인경우시술후 CT로선량측정을하였을때 선량분포의적절성이보장되었다고보고하였다. Salembier 등 21) 은 ESTRO/EAU/EORTC 권고안의보충안에서전립선에서각방향으로 3 mm 확장하여계획용표적체적을정한후이부피에대해선량분포를 V 15 5%, V 1 95%, D 9> 1% 의기준을맞추도록권고하고있다. 또한직장선량은 D 2cc<145 Gy, D.1cc (-Dmax)<2 Gy로권고하고있다. 본연구에서는전립선에서부피확장을하지않고선량을측정하였으며, 평균 D 9 은 Gy, 평균 V 1 은 99.2%, 평균 V 15 은 92.4% 으로 V 1 을제외하고기존보고들의권고에비해다소높은선량분포를보였다. 전립선근접치료로인한직장염에대한보고들을살펴보면 RTOG grade 2의후기직장합병증은 %, RTOG grade 3, 4의직장합병증은 <1 8% 로보고되고있다. 22) 그리고직장누공의발생률은초기에발표된보고들에서는 <1% 에서 7% 이었으며평균발생률은 2.6% 로보고되었으나최근에는 1% 의발생률이보고되고있다. 22) Wallner 등 23) 은전립선근접치료의조기결과보고에서직장궤양의발생률에대하여 1% 가량이라고보고하였으나, 근접치료경험이누적된후발표한연구에서는 1% 로감소한발생률을보고하였다. 24) Kleinberg 등 25) 은무증상의직장출혈또는궤양이 47% 에서발생하였으며삽입후 1, 2개월내에배변습관이나양상변화가 25% 에서관찰되었다고보고하였다. 직장부작용이나타나는선량및부피에관한연구들에서 Snyder 등 26) 은처방선량을받는직장벽의부피가 1.3 cm 3 이하일경우 5년내에 grade 2의직장염이생길확률은 5% 미만이며, 1.3 cm 3 이상일경우 18% 이라고보고하였으며, Waterman과 Dicker 27) 는 1 Gy 이상을받는직장표면면적의비율이근접치료후 Grade 2 후기부작용의예측인자라고보고하였다. 또한 1, 15, 2 Gy를대략 3%, 2%, 1% 의직장표면에받을경우 5% 이하의후기부작용을보인다고보고하였으며, 직장최대선량이 15, 2, 25 Gy일때직장염가능성은.4%, 1.2%, 4.7% 라고보고하였다. Albert 등 28) 은 1 Gy 이상을받는직장부피가아르곤플라즈마응고소작술을필요로하는직장출혈의예측인자라고보고하였으며 1 Gy 이상을받는직장부피가 8 cc 이하일경우지혈술이필요한환자는없었으며그이상일경우 3년추적관찰결과 2% 에서필요로하였다고보고하였다. Han과 Wallner 29) 는 9명의방사선직장염환자와 18명의직장염이없는환자군의 1% 처방선량을받는직장의부피를비교한연구에서직장염환자군에서는 2.5 cm 3, 대조군에서는.6 cm 3 이었다고보고하였
8 다 (p<.8). 본연구에서는 43명중 3명의환자에서직장누공이발생하여 7% 의발생률을보였으며, RTOG grade 2의만성직장염이 1명 (23.3%) 에서발생하여최근연구들에비해다소높은발생률을보였다. 또한 RTOG grade 2의만성직장염이발생한환자군의전체직장의 V 1 은평균 9.31%, 4.4 cc, V 15 은평균 3.16%, 1.33 cc이었고 RTOG grade 4의직장염이발생한환자군의전체직장의 V 1 은평균 1.62%, 5. cc, V 15 은평균 3.67%, 1.76 cc로부작용의발생이적었던연구들에비해고선량을받은부피가크게나타났다. 방사선직장염의가능성은직장벽에들어가는선량및부피의증가와연관되어있으므로 8,22) 치료계획시에주변장기선량분포를고려하여선량증가로인한주변장기부작용가능성의증가와국소제어율간에균형을맞추어야할것으로생각된다. 본원에서근접치료시술시전계획을세우는과정에서손상위험장기의선량분포에대한검증을시행하는과정을시행하지않고전립선의선량만을확인하였으나, 경직장초음파영상을바탕으로직장선량을예측하여 seed 삽입위치와개수를조절하는과정이추가되어야할것으로판단된다 (Fig. 2).

Merrick 등 31) 은예방적알파차단제사용이요로계부작용을줄이는효과가있다고보고하였다. Merrick 등 32) 은또한외부방사선치료를추가하는것이저 위험군과중간위험군환자에서는이익이없으며, 혈뇨의발생및후기요정체를증가시키고, 발기부전및대장기능을저하시킨다고보고하였다. 본연구에서는방광목의최대선량, 전립선크기, 근접치료전호르몬제사용여부모두요로계부작용의정도에유의한차이를보이지않았으며사용된 seed 개수가급성요로계부작용의정도와연관성을보였다. 반면 Pinkawa 등 33) 은 seed 강도가.65 mci 이하인경우와삽입된 seed의개수가많은경우선량이고루분포하여요로계부작용이감소하였다고보고하였다. Masucci 등 34) 은평균.44±.163 mci와.61±.178 mci의 seed를사용하였을때 seed 강도가높을경우요로계부작용이더많았다고보고하였다. 그외에 Lee 등 35) 은사용된 needle의개수가 33개이상인경우요폐색이오히려증가한다고보고하였다. 기존에보고된연구에서는본연구에서의 seed 강도보다높은강도의 seed를사용하였기때문에낮은강도에서도 seed의개수와강도의차이가요로계부작용에영향을미치는지에대해서는보다많은수의환자를대상으로부작용의양상을조사하여야할필요가있을것으로생각되며이결과가도출되어야근접치료에적합한 seed의강도와개수를정할수있을것으로생각된다. 본연구에서는모든환자가호르몬치료를시행하였다. 외부방사선치료와호르몬치료를병용하였을때생화학적재발률이감소한다고보고되고있으며, 36) 국소진행된전립선암에서외부방사선치료와호르몬치료를병용할경우생화학적재발률이 1% 감소하였다고보고되었다. 37) 그러나 Potters 등 38) 은후향적대응쌍분석에서모든위험군에서근접치료와호르몬치료의병용이근접치료단독과비교하여생화학적재발률에영향을미치지못하였다고보고하였다. 반면에 Merrick 등 32) 은근접치료단독과외부방사선치료병용으로치료받은환자의비율이각각 92.6% 와 7.4% 로구성된고위험군에서호르몬치료가생화학적재발률에유의한연관이있었다고보고하였다. 호르몬치료의추가가근접치료의생화학적조절률에미치는영향에대해서는연구에따라다양한결과들이보고되고있으며, 본연구결과에호르몬치료의추가가영향을주었는지의여부를판단하기위해서는호르몬치료기간및방법에따라많은수의환자군을대상으로한추가적인연구가있어야할것으로생각된다. 본연구는최소추적관찰기간이 2년으로단기간의치료성적이지만 95.3% 의높은생화학적조절률을보였다. 장기간추적관찰을통해치료성적을검증할필요가있으나국소전립선암환자에서근접치료는저위험군환자뿐만
10 아니라중간위험군및고위험군환자에서도선택적으로적용가능한치료방법이라고판단되며환자의신체상태나삶의질에영향을미치는요인들에대한환자의가중치에따라치료방법이결정되어야할것으로생각된다. 또한직장부작용을감소시키기위한노력이병행되어야할것으로생각된다. 참고문헌 1. Marcus DM, Jani AB, Godette K, Rossi PJ.

12 Abstract Permanent Brachytherapy of Localized Prostate Cancer: Preliminary Results Hyeli Park, M.D., Sei Kyung Chang, M.D., Jayoung Kim, M.D., Bo Mi Lee, M.D., Seong Young Ko, B.S., Sung Joon Kim, M.S., and Hyun Soo Shin, M.D. Department of Radiation Oncology, CHA Bundang Medical Center, CHA University, Seongnam, Korea Purpose: To evaluate the biochemical control rate and the rate of side effects after performing permanent brachytherapy of localized prostate cancer. Materials and Methods: 67 patients with localized prostate cancer were treated with brachytherapy between April 27 and December 28. Of these, 43 patients who were followed up and did not receive external radiotherapy were evaluated for the change in prostate specific antigen (PSA) level and the occurrence of side effects. In total, 18 patients were classified as low risk, 19 patients as intermediate risk, and 6 patients as high risk. The prescription dose was 145 Gy. Results: A PSA increase greater than 2 ng/ml occurred in 2 patients (4.7%). Radiation Therapy Oncology Group (RTOG) grade 1 and 2 acute urologic complications (UC) occurred in 4 and 3 patients, respectively. Further, 5 patients had RTOG grade 1 acute rectal complication (RC). The numbers of RTOG grade 1, 2, and 3 chronic UC were 1, 4, and 1, respectively. The numbers of RTOG grade 1, 2, and 4 chronic RC were 5, 1, and 3, respectively. The statistically significant risk factors (RF) of acute RC were the minimal dose in the most irradiated.1 cc volume (D.1CC, p=.41) and absolute volume receiving 15% of the prescribed dose (V 15cc, p=.38) in the entire rectum (ER). The percentage (V 1%, p=.19) and absolute volume (V 1cc, p=.47) in the involved rectum (IR) were also statistically significant. The RF of chronic RC were V 1% (p=.11) in the ER and the D.1cc (p=.49), V 1cc (p=.23) in the IR. The number of used seeds were related with acute UC (p=.28). Conclusion: Permanent brachytherpy of localized prostate cancer showed a favorable short term biochemical control rate. As such, selective intermediate and high risk patients can be managed with permanent brachytherapy. The effort to reduce rectal complication is also necessary.
