Limited disease small cell lung cancer: alternating combination of doxorubicin, etoposide, ifosfamide and hyperfractionated radiotherapy. Final results of a multicentric pilot study for the Groupe Lyonnias d'Oncologie Thoracique (GLOT).
In order to evaluate the effect on prolonging survival of alternating chemotherapy and radiotherapy schedules in patients with limited disease small cell lung cancer, 89 patients were included in a multi-institutional pilot study between January 1986 and May 1989. Treatment consisted of induction chemotherapy using the combination of doxorubicin, etoposide and ifosfamide (AVI) for four consecutive courses, followed by two cycles of the VI chemotherapy alternating with three hyperfractionated radiotherapy courses and then followed by two additional courses of AVI. Objective response to the four cycles of AVI combination was observed in 65 patients (75%). Thirteen out of 30 patients (44%) who were in partial response (PR) after induction chemotherapy were converted into complete response (CR) after the three alternating courses of chemotherapy and radiotherapy. The principal side effect related to combined modality treatment was acute radiation pneumonitis (21.5% cases) reversible except one which resulted in toxic death, and a second with chronic lung fibrosis with permanent WHO Grade 2 dyspnea (14%). Local relapse was observed in 47% of the patients who were considered in CR at the end of the treatment program and cerebral metastases were the first site of detectable relapse in 25% cases. The 3-year actuarial disease-free survival of the 89 patients is 5%, and the median actuarial survival is 14 months. This study shows that the promising survival rates seen in our previously published interim analysis were not maintained. Reasons for this might include the choice of a non cisplatinum containing induction chemotherapy, the late introduction of thoracic irradiation and/or to the use of non-restrictive criteria for selecting patients.
