Abstract

Aim: The objective of this study is to demonstrate the efficacy of induction or consolidation chemotherapy on survival in locally advanced non-small cell lung cancer ( NSCLC) patients who were treated by curative concurrent chemoradiotherapy (CCRT).Material and Methods: Patients were randomised to CCRT, induction chemotherapy followed by CCRT or CCRT followed by consalidation chemotherapy retrospectively. A platinum-based doublet cytotoxic chemotherapy regimen used as induction/consalidation. Patients who received 60 Gy or more were included in the study. These patients had received two or more cycles of platinum-based chemotherapy concurrently with definitive radiation therapy. Results: A total of 114 patients were included in the study. 32 (28%) patients were in CCRT arm; 54 (47%) patients were in induction arm and 28 (25%) patients were in consalidation arm.Median overall survival (OS) was found as 21.9±14.0 months and 2 year and 3-year survival as %46 and 33% in all patients. Median OS did not differ between arms; with a median OS of 29.7±8.8 months, 23±2.9 months and 16.8±3.5 months in the CCRT arm, in the induction arm and in the consolidation arm (p:0.54). The 2 years OS was 53%, 50% and 32% (p:0.48) and 3 years OS was 40%, 33% and 25% ( p:0.40) in the CCRT arm, the induction arm in the consalidation arm without a significiant difference. Conclusion: In this retrospective study, platin-based chemotherapy as induction or consolidation with concurrent chemoradiotherapy failed to further prolong OS. The standart of care for unresectable stage III NSCLC is still concurrent chemoradiotherapy .

Özet

Amaç: Bu çalışmanın amacı eşzamanlı kemoradyoterapi ile tedavi edilen küçük hücreli dışı akciğer kanserinde (KHDAK) indüksiyon veya konsalidasyon kemoterapilerinin yalnızca kemoradyoterapi (KRT) ile karşılaştırıldığında sağkalıma etkinliğinin araştırılmasıdır.Gereç ve Yöntemler: Lokal ileri evre KHDAK tanısı ile eşzamanlı kemoradyoterapi ± indüksiyon/konsalidasyon tedavisi alan 114 hastanın dosyaları retrospektif olarak incelendi. İndüksiyon veya konsalidasyon tedavisi olarak platin temelli ikili kemoterapi rejimi kullanıldı. 60-66 Gy torasik radyoterapi ile eşzamanlı tek ajan platin( sisplatin veya karboplatin), platin+etoposid veya platin+taksan içeren kemoterapi protokolleri uygulandı. Sonuçlar: Çalışmaya dahil edilen 114 hastanın 32 (28%)'si KRT; 54 (47%) 'si indüksiyon ve 28 (25%)' si konsalidasyon kolundaydı. Tüm hastalar için ortanca sağkalım 21,9±14.0 ay; 2 ve 3 yıllık sağkalım oranları ise %46 ve %33 olarak bulundu. KRT; indüksiyon ve konsolidasyon kemoterapisi alan hastaların ortanca sağkalımları sırası ile 29,7±8,8 ay; 23±2,9 ay ve 16,8±3,5 ay olarak saptanmış olup anlamlı farklılık yoktu( p=0,54). 2 yıllık sağkalım oranları KRT kolu için 53%; indüksiyon kolu için 50% ve konsalidasyon kolu için 32% ( p=0,48) ; 3 yıllık sağkalım oranları ise sırası ile 40%, 33% ve 25% ( p=0,40) olarak saptanmış olup benzerdi. Sonuç: Bu retrospektif çalışmada, eşzamanlı kemoradyoterapiye eklenen indüksiyon veya konsolidasyon kemoterapisinin genel sağkalımı uzatmadığı gösterilmiştir. Rezeke edilemeyen evre III KHDAK için standart tedavi hala eş zamanlı kemoradyoterapidir.
