This study evaluated tolerance, local control, and short-term survival in patients with locally advanced non-small-cell lung carcinoma treated with induction chemotherapy followed by radical hyperfractionated radiotherapy with concurrent chemotherapy.
Thirty-one patients with stage IIIa (N2) or IIIb tumors were treated with cis-platinum-based induction chemotherapy for 1 to 4 courses followed by radical hyperfractionated radiotherapy (69.6 Gy) with concurrent chemotherapy given at the beginning and end of radiotherapy. Induction chemotherapy produced no complete responses and 18 (58%) partial responses. After completion of radiotherapy, 4 patients had complete response (13%) and 23 patients (74%) partial response. The patterns of failure were as follows: intrathoracic, 6 patients (22%); intrathoracic + distant metastasis, 6 patients (22%); distant metastasis without thoracic failure, 5 patients (19%). Six patients of the 12 with intrathoracic failure experienced in-field radiotherapy pure local failure. At the time of this analysis, 10 patients were alive and well (4 complete and 6 partial responders). Actuarial survival projected at 39 months is 35%. No benefit was observed for those patients responding to induction chemotherapy. Toxicity was as follows: grade III neutropenic fever in 4 patients (13%), grade IV neutropenia in 13 patients (42%), pneumonia in 6 patients (19%), grade III esophagitis in 4 patients (13%) and severe clinical pneumonitis in 1 patient (3%).
Induction chemotherapy followed by chemoradiotherapy is feasible, and the preliminary results are encouraging. Complete response after radiotherapy appeared to be related to short-term disease-free survival, and decisions based on the response to chemotherapy may be equivocal.
