Postoperative bronchopulmonary complications in stage III lung cancer patients treated with preoperative paclitaxel-containing chemotherapy and concurrent radiation.

We previously observed encouraging results and acceptable toxicity in phase II trials testing preoperative split-course thoracic radiation and simultaneous cisplatin, etoposide, and 5-fluorouracil in stage III non-small cell lung cancer patients. We decided to delete 5-fluorouracil and to incorporate paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) into our combined-modality treatment. The first group of patients received carboplatin dosed at an area under the concentration-time curve of 4 on day 2, etoposide 50 mg orally days 1 to 5 and 8 to 12, cisplatin 50 mg/m2 on day 21, and paclitaxel 35 mg/m2 escalated to 45 mg/m2 on days 1 and 8. Group 2 patients received carboplatin dosed at an area under the concentration-time curve of 4 on day 1, etoposide 45 mg/m2 intravenously daily on days 2 to 5, and paclitaxel 80 mg/m2 (escalating to 120 mg/m2) on day 1. Patients in group 3 received carboplatin dosed at an area under the concentration-time curve of 4 on day 1 and paclitaxel 120 mg/m2 (escalating to 140 mg/m2) on day 1. Each patient received radiation 2 Gy daily on days 1 to 5 and 8 to 12, and a total of two cycles was given at 28-day intervals. Twenty-one patients received preoperative chemoradiotherapy: group 1, five patients; group 2, 11 patients; and group 3, five patients. Thoracotomy was not done in five patients due to cerebrovascular accident in one and progressive tumor in four. The remaining 16 patients had the following procedures: pneumonectomy, eight; lobectomy, six; chest wall resection, one; and no resection, one. Postoperative complications included bronchopleural fistula in one patient each in groups 1 and 3, hypoxia in one patient in group 1, pulmonary hypertension in one patient in group 2, pneumonia in one patient in group 2, and adult respiratory distress syndrome in one patient in group 3, which proved lethal. Thus, six of 16 patients had serious postoperative complications. The relatively high incidence of postoperative bronchopulmonary complications suggests that the use of preoperative paclitaxel-containing chemotherapy and simultaneous thoracic radiation may not be feasible.
