Anti-cancer treatments for various subtypes of cancer have significantly improved. As a result, the number of cancer patients who cannot be completely cured but may live for a considerable period of time is growing. A 72-year-old woman was diagnosed with metastatic EGFR-mutated non-small-cell lung cancer. She received anti-tumour treatment with gefitinib for almost two years and experienced only limited side effects. She was anxious about not knowing her prognosis but after visiting a psychologist she feels as if she can continue life. A 46-year-old woman started to experience symptoms of depression two years after treatment for metastatic breast cancer. A visit to a psycho-oncologist proved to be very helpful. She does not want to know her prognosis and is particularly happy that everything is going well at present. These two cases illustrate that patients living longer with incurable cancer may experience specific dilemmas. We make several recommendations for the care of this group of patients.
