Japanese doctors' preferred treatment choices for their hypothetical non-small cell lung cancer: how they would wish to be treated. National Chest Hospital Study Group for Lung Cancer.

We conducted a trial to clarify what Japanese clinical doctors think about the present status of therapy for non-small cell lung cancer, as well as to clarify which problems are still unresolved. One-hundred five Japanese doctors who treat lung cancer patients were asked how they would choose to be treated, if they suffered from non-small cell lung cancer. Six scenarios were presented and the doctors had to choose one treatment method for each of the six scenarios. Adjuvant chemotherapy or radiotherapy after complete resection, increase with progression of the pathological stage. Ninety-three per cent of Japanese doctors wanted surgery, even if mediastinal lymph node metastases were present. In the scenario of only one distant metastasis to the brain, 44% of doctors wanted surgery while 39% wanted chemotherapy and/or radiotherapy. In the scenario of multiple bone metastases, 33% wanted chemotherapy, 77% did not. It was concluded therefore that Japanese doctors choose surgery as the number one treatment modality when all lesions are considered resectable.
