Radiotherapy Versus Rasiotherapy Enhanced By Cisplatin İn İnoperable Nonmetastatic Nonsmall Cell Lung Cancer ( Nsclc ) : Preliminary Results Of a Randomized Study

Year 1995, Volume: 12 Issue: 4, - , 23.12.2009

Abstract

Csplatin (cis-diamminedichloroplatinum) has been reported to enhance the cell killing ef¬fect of radiation, an effect whose intensity varies with the schedule of administration. We randomly assigned 53 patients with nonmetastatic inoperable nonsmall cell lung cancer to one of two treatments; radiotherapy for 6-7 weeks (2 Gy given 32 times, in five fractions a week) or radiotherapy in the same schedule, combined with 20 mg/m2 cisplatin, given on days 1-5 of the second and sixth treatment weeks. An overall response rate of 48% was observed in radiotherapy alone group and 64% in the combined treatment groups. Median time to progression was 8 months for radiotherapy alone group and 10 months for the other group. One-year survival rates were 45% and 60%, respectively. Toxicity was accep¬table and no treatment related death occured in either treatment schedule. In this study no significant advantage of the combined treatment over radiotherapy alone was found.


Bu çalışmada sisplatinin (cis-diamminedichloroplatinum) radyoduyarlığı artırıcı etkisi değerlendirilmiştir. Bu amaçla hastalar iki randomize gruba ayrılmış; birinci gruba stan¬dart fraksiyone radyoterapi (günde 2 Gy'den 6-7 haftada 64 Gy), ikinci gruba ise radyote¬rapiye ek olarak tedavinin 2. ve 6. haftalan tedaviden bir saat önce 5 gün süre ile 20 mg/ m2 sisplatin verilmiştir. Tek başına radyoterapi grubunda %48 yanıt elde edilirken, bu oran kombine tedavi grubunda %64'tür (p>0.05). iki grup arasında yineleme yerleri bakımından bir farklılık saptanamamıştır. Medyan progresyon süresi tek başına radyote¬rapi grubunda 8 ay, kombine tedavi grubunda ise 10 aydır. Bir yıllık yaşam oranı tek başına radyoterapi uygulanan grupta %45 iken, bu oran kombine tedavi grubunda %60 olarak bulunmuştur (p>0.05). Kombine tedavi grubunda tedaviye tolerans oldukça iyi olup: tedaviye bağlı ölüm olayına rastlanmamıştır. Kombine tedavi grubunda elde edilen yanıt ve yaşam oranlannın daha yüksek bulunmasına karşın iki grup arasında istatistik¬sel olarak anlamlı bir farklılık gözlenmemiştir.
