[Neoadjuvant combined therapy in stage IIIA if non-small-cell bronchial cancer].

BACKGROUND AND OBJECTIVE

The overall prognosis of patients with stage IIIA non-small-cell lung cancer is unfavourable (median survival time 12 months). Tolerance to and efficacity of a multimodal neoadjuvant treatment was assessed in a prospective study.

PATIENTS AND METHODS

25 patients (median age 59 [37-69] years), with histologically confirmed mediastinal lymph node metastases, underwent chemotherapy. Immediately after two cycles with carboplatin/Ifosfamid (dimethoate)/etoposide they received hyperfractionated accelerated radiotherapy (45 Gy; 2 x 1.5 Gy daily) with simultaneous administration of carboplatin and vindesine. This was followed by tumour resection.

RESULTS

After conclusion of the neoadjuvant treatment 19 of 25 patients (76%) had a remission. Of the 20 operated patients complete resection (R0) was possible in 17 (85%) and 14 of the 20 patients with resection (70%) had histologically demonstrated marked tumour regression. Critical toxicity consisted of pneumonitis and bronchial stump problems. Median survival time of all patients was 24.8 months and for patients with R0 resection 35.9 months.

CONCLUSION

Neoadjuvant multimodal treatment of stage IIIA non-small-cell lung cancer can achieve prolongation in survival time. The place of radiotherapy or radiotherapy with chemotherapy in such a treatment concept will need to be defined in a randomized study.
