Total atelektazi yapmış akciğer kanserli olgularda eksternal radyoterapinin palyatif etkisinin retrospektif olarak değerlendirilmesi

Büyük hava yollarının tümörle tıkanması sonucu oluşan atelektazi ve pnömoniler, akciğer fonksiyonlarının azalmasına ve olgularda ciddi solunum yetmezliği semptomlarının ortaya çıkmasına neden olmaktadır. Prognozu kötüleştiren bu durumun hızla tedavi edilmesi büyük önem taşımaktadır. Cerrahpaşa Tıp Fakültesi Radyasyon Onkolojisi Ana Bilim Dalımızda 1980-1996 yılları arasında 27 total atelektazi olgusuna palyatif eksternal radyoterapi uygulanmıştır. Olgulardaki toplam radyolojik yanıt %74 (20 olgu), toplam sübjektif yanıt %65 (17 olgu) bulunmuştur. Radyoterapi sonunda öksürük şikayetinde %54.3, dispnede %58.3, hemoptizide %80, ağrıda %54.5 palyasyon sağlanmıştır. Sonuç olarak, eksternal radyoterapi, total atelektazili olgularda başarıyla uygulanabilen tedavi yöntemlerinden biridir.

The retrospective evaluation on the palliative effect of external radiation therapy in patients with total atelectasis of lung cancer

Background and Design.- We evaluated the effect of radiation therapy in 27 patients with total atelectasis with lung cancer, between January 1980 and December 1996. The mean age of the patients was 56 years (31-87) of whom 26 were males. The patients were treated by primary radiation therapy, with doses ranging from 3000 to 6600 cGy. Initial symptoms included dyspnea in 24 (%88.8), cough in 22 (%81.4), hemoptysis in 5 (%18.5) and pain in 11 (%40.7) patients. The response of atelectasis to radiation therapy was established on the basis of follow-up chest roentgenograms. Follow-up was 1 to 24 months (median 6 months) Results.- Tweenty-seven patients with ob-structive atelectasis were treated with external radiation therapy. Subjective response was achieved in %65 (17) of cases, objective response was %74 (20) of the cases. Dyspnea improved in %58.3, cough in % 54.3, hemoptysis in %80, pain in %54.5 of the patients. Twelve of 20 patients (%60), who had receive objective responses were treated with doses ranging from 5000-6600. Conclusion.- Radiotherapy is a feasible treatment modality of total atelectasis developed by means of lung cancer.
