[Short-term induction and cyclic maintenance therapy in inoperable small cell bronchial cancer].
Since July 1978 one hundred and three consecutive patients with unresectable small cell bronchogenic carcinoma were treated with a combination of doxorubicin, cyclophosphamide and vincristine (ACO). In limited disease patients (64) the second chemotherapy course was followed by prophylactic cranial irradiation, the fourth by irradiation towards primary disease sites. Complete responders were randomised to either receive etoposide or no further maintenance therapy. Objective responses were reached in 88/100 evaluable patients, with 72% of complete remissions in limited-stage disease and 33% in extensive disease, respectively. The actuarial median survival time for limited disease patients was 15.8 months compared to 9.3 months in extensive disease (p less than 0.005). 29 of the 100 patients remain still alive, 4 for more than 24 months without disease recurrence. The survival advantage of patients reaching complete remissions relative to those who did not is highly significant (p less than 0.001). Acute gastrointestinal and hematological side effects were common, with possibly three drug-related deaths from infections during transient granulocytopenia (mean nadir: 600-900 cells/mm3). The present induction regimen using only four courses of chemotherapy produces high complete remission rates on roentgenography and bronchoscopy and improved survival in the majority of patients. Thus far any effectiveness of etoposide-maintenance therapy following ACO could not be substantiated.
