Successful salvage surgery following multimodal therapy in a patient who harboured ALK-rearranged advanced lung adenocarcinoma with multiple organ metastases

Abstract

The prognosis of stage IVb non-small cell lung cancer (NSCLC) patients with multiple distant metastases or involvement of different extra-thoracic sites is poor. The prognosis following salvage surgery for patients with more than five metastases has been reported as most unfavourable. The following case is of a 71-year-old man with a 9-year survival duration after being diagnosed with stage IVb ALK-rearranged lung adenocarcinoma, who was treated for 6 years with whole-brain radiotherapy, pemetrexed-based chemotherapy, ALK-tyrosine kinase inhibitors (TKIs) including ceritinib and alectinib, and salvage sublobar resection of the primary lung cancer and who obtained treatment-free remission (TFR) for more than 3 years following surgery.
