There is no specific data on survival time after treatment for patients with advanced cancer who show signs of talking nonsense. Cancer is a highly malignant disease caused by a combination of internal and external factors. In the advanced stage of the disease, encephalopathy or intracranial metastasis may occur, which may lead to the clinical manifestation of talking nonsense. In this period, due to the complexity of the disease and the poor physical condition of the patient, there is no opportunity for surgery. Therefore, non-surgical therapies such as radiotherapy, chemotherapy, and targeted therapy are often used to treat the disease. After active treatment, if the patient has a high degree of tolerance to the treatment, the survival time can be slightly prolonged. However, the purpose of treatment in this period is to improve the quality of life and prolong the survival of patients.
