Some primary thrombocythemia can live up to 40 years, but exactly how long is not certain. 1. Clinical data show that the survival time of the low-risk group of primary thrombocythemia is basically the same as that of the healthy population. If early detection and active treatment can be achieved, basically normal quality of life can be achieved. Drugs include hydroxyurea, aspirin and so on. 2. For the survival time of high-risk patients, there are many influencing factors, so the survival time will vary. Some patients may convert to myelofibrosis or even leukemia through several years or even longer, but the overall conversion rate is very low. However, most patients can survive for a long time as long as they are detected early, treated effectively and in the right way to control the progression of the disease. In the absence of serious complications, life expectancy in primary thrombocythemia is not significantly different from normal. With the progress of modern medicine, complications are controlled and elderly patients can prolong their survival. Patients do not need to be overly nervous, but should pay attention to the prevention and treatment of bleeding, thrombosis and complications. Drug use is under the guidance of physicians.
