Patient's Query

Hi doctor,

My wife has a JAK2 (Janus kinase 2) positive myeloproliferative neoplasm with thrombocytosis, likely essential thrombocytosis. What does that mean? Does she have cancer or not? I need a fast and accurate answer. Does this mean she has cancer or not? What is life expectancy? Is there any cure? Your right to the point answer is much appreciated.

Hi,

Welcome to icliniq.com.

I am a hematologist with 20 years of experience. I hope you and your family are doing well in this pandemic.

JAK2 positive myeloproliferative neoplasms mean it is some cancer. JAK2 is a mutation in a gene that leads to unlimited production of platelets in your case.

Life expectancy in this cancer is very good. It might be up to decades. Usually, this type of cancer is presented with thrombosis of leg veins, leg arteries, heart vessels, brain vessels, and lungs vessels. The occlusion of heart, lung, and brain vessels has significant morbidity and mortality. JAK2 positive itself is not a very big problem. The person having this disease does not die of this disease rather they die along with this disease. The main aim is to control the proliferation of platelets. There are different means to do so. By cytoreductive medicines like hydroxyurea, and JAK2 inhibitors rock you little noob by plasmapheresis. The main aim of the treatment is to keep platelets below 1 million. In your case, the platelet is well within limits. Sometimes this disease can be cured, or otherwise, it would be controlled. The control means this disease would not cause platelet-induced vessel occlusion in the body's brain, lungs, heart, and other blood vessels. This is achieved by antiplatelet medication. For this purpose, low-dose Aspirin or Clopidogrel (anti-platelet) is prescribed once daily.

Patient's Query

Hi doctor,

Thank you for your feedback.

Another question. My wife started putting a copper-made IUD (Intrauterine contraceptive device) to prevent pregnancy. During the past few years, I have observed and noticed that she began having migraines and headaches, and bleeding during her period. I am getting suspicious that the increase in her platelets count might be due to heavy bleeding or inflammation due to the IUD.

Is it possible, doctor, that might be the reason besides her having a JAK2 gene mutation?

Do you suggest that I ask her to remove the IUD device, making her bleed less during the period? Or is it better to keep it since it is bleeding more, which is better to her since this is how blood is recirculating and hence getting rid of platelets?

Your input in this matter is much appreciated. Thanks for your time and efforts.

Hi,

Welcome back to icliniq.com.

It is good to see you again. IUDs are associated with menstrual abnormalities such as increased bleeding, and increased bleeding is also associated with increased platelets. But JAK2 is an entirely different phenomenon. It is a genetic change, leading to thrombocytosis. It is nothing to do with IUDs. And, increased blood flow will not eliminate the increasing cells because it is a disorder related to increased production of platelets, not due to decreased destruction. Instead, increased bleeding would contribute to increased production of platelets and lead to micronutrient deficiency, especially of Iron. In my opinion, if an IUD is creating a problem, it should be removed, and alternative methods of contraception should be used. P. S. (Progesterone) Hormone pills AKA OCPs (oral contraceptive pills) are also contraindicated in JAK2 positive disorders.

Same symptoms don't mean you have the same problem. Consult a doctor now!
