Abstract
The author presents case reports of two patients who have been receiving long-term treatment for advanced ALK-driven lung adenocarcinoma with the use of a number of therapeutic modalities including several lines of chemotherapy. The first patient received several lines of systemic treatment and palliative brain irradiation; the other patient had lung surgery and mediastinal irradiation as well as surgery for brain metastasis; both patients were successively treated with crizotinib and ceritinib, and have now been on treatment with alectinib for more than three years.
They both underwent repeat treatment for small brain metastases using the Leksell gamma knife. The two patients have been alive for more than 13 and 10 years since diagnosis, respectively.
