What tumor marker is thymidine kinase?

Under normal circumstances, thymidine kinase is a biomarker for thymic cell tumors. The specific analysis is as follows:

Thymidine kinase is an enzyme involved in DNA synthesis, and its activity is relatively low in normal thymus tissue. However, in malignant conditions such as thymic cell tumors, thymidine kinase activity is significantly elevated, making it a useful biomarker for these tumors. Symptoms of thymic cell tumors may include chest pain, shortness of breath, cough, sputum production, and chest tightness. Specific symptoms can vary depending on the tumor's location and size. Patients may be treated with medications such as vincristine sulfate for injection or mitomycin for injection, as prescribed by a physician.

If patients experience any discomfort, they are advised to seek timely medical attention at a hospital to avoid delays in diagnosis and treatment.
