RESUMO
A combination of cisplatin (70 mg/m2 i.v. day one) and etoposide (100 mg/m2 i.v. day one, 200 mg/m2 orally days 2 and 3) repeated every third week to a maximum of 4 cycles were compared with high voltage radiotherapy, 42 Gy given in 15 fractions over a 3-week period to patients with inoperable non-small cell lung cancer (a shield was used in the posterior field to reduce the total spinal dose less than 40 Gy). One hundred and eighteen patients received radiotherapy; the median survival was 10.6 months compared to 10.5 months for the 116 chemotherapy patients (p = 0.81). The objective response rate (CR + PR) was 42% for the radiotherapy and 21% for the chemotherapy group (p = 0.009). At progression it was optional to cross over to the other treatment modality or to receive phase II chemotherapy. Thirty patients primarily treated with radiotherapy and 54 allocated to chemotherapy received second line antineoplastic treatment.
