Introduction
There are many reasons for fever in patients with advanced cancer, and it does not necessarily indicate disease progression; symptomatic treatment should be directed according to the underlying cause. In addition, the causes of fever in some patients with advanced tumors are not yet fully understood and require further research. Therefore, in the late stages of cancer, regardless of the cause, fever generally reflects tumor progression or deterioration, which is usually a poor prognostic sign.
There are many reasons for fever in advanced cancer patients, and it does not necessarily indicate disease progression. Symptomatic treatment should be directed according to the underlying cause.
1. Tumor-related fever
Malignant tumors grow rapidly, leading to relative tissue ischemia and hypoxia, followed by necrosis. After treatment, a large number of tumor cells are destroyed and release tumor necrosis factors, while tumor cells may also secrete certain bioactive substances. These factors can all potentially cause fever. In such cases, timely cooling measures and anti-tumor therapy are required.
2. Infection
Patients with advanced cancer often have reduced immunity due to surgical procedures, radiotherapy, chemotherapy, or the disease itself, making them susceptible to infections caused by bacteria, viruses, and other pathogens. This leads to inflammatory responses and fever, possibly accompanied by symptoms such as cough, sputum production, and chills. Active anti-infective treatment is necessary in these situations.
3. Tumor lesions compressing or infiltrating the body's temperature regulation center
This occurs in primary brain cancers or brain metastases, where dysfunction of the neural regulation of body temperature leads to fever. Under medical guidance, corticosteroids can be administered to alleviate inflammatory responses in late-stage cancer and help regulate abnormal thermoregulatory responses caused by tumors.
In addition, the exact causes of fever in some patients with advanced cancer remain unclear and require further research. Therefore, in the late stages of cancer, regardless of the specific cause, fever generally reflects tumor progression or deterioration.
