Everything you wanted to know about Optune (but were afraid to ask)

Now that I am back on Facebook (yay!) A few people have been interested in Optune, the new treatment I am undergoing. Here are a few questions answered about this fascinating device. In the interest of education and passing on what I am learning, I am using some information from the patient packet to complete this. I am having a bit of trouble getting pictures on here, but I hope to put them here eventually.

What is Optune?
Optune is a treatment for glioblastoma patients 22 years or older. Optune delivers electric fields (called TTFields) that stop cancer cells from dividing and also destroying some cancer cells. It has been proven that, in conjunction with chemotherapy like Temodar, it has extended survival rates for GBM patients.

What does it look like?
The unit itself is in a small bag that can go over the shoulder, or can be carried hand-held. There is also a backpack available to carry the device.It is connected to four arrays that adhere to the scalp. It can be powered by electricity via a wall plug (ideal for sleeping or work), or with lithium-ion batteries for portability. The unit comes with four batteries, and a charger that holds three of them.

Does it hurt to wear it?
No, if it is applied correctly. The only thing I feel is a small amount of warmth from the arrays.

How do you put it on? 
First, your scalp needs to be completely shaved. An electric razor is included that seems to work well. Next, you need to swab your scalp with isopropyl alcohol. Then, you apply the four arrays. The location and placement of the arrays depends on the location of the tumor and the size of the patient's head. This process needs to be repeated with new arrays every 2-4 days depending on hair growth.

Are there any side effects?
Not really. Some patients have complained about sores and irritation on the scalp, and that is usually caused by too much hair on the scalp. If you shave your head and replace the arrays regularly, you should be able to avoid this. Luckily, I have one of the most anal caregivers you can possibly have.

How often are you supposed to wear it?
The FDA recommends 18 hours per day minimum. Optimum is 22 hours per day. You are supposed to sleep with the device on. Aside from the first night, I have had few problems sleeping with it, even while using it with a CPAP (for sleep apnea).

Can you wear something over the arrays?
Yes, you can wear a breathable wig or hat over the arrays.

Can it get wet?
No, you should take it off if it rains, and take it off or use a shower cap when bathing.

Can you talk on a cell phone while using Optune?
Yes. There have been no reported problems related to using the Optune device with a cell phone.

Does insurance cover Optune?
Although the device is approved by the FDA, the actual cost of the device and supplies is very high. The supplier itself provides financial support, and we were lucky enough that our medical insurance (through Penn State) approved it right away. Jaci thinks it is because my file was "flagged" by the insurance company because they did not approve a head CT back in January, and we could sue them if we wanted to.

Can Optune be used for other types of cancer?
As of now, it is used exclusively for GBM. They are supposedly working on adapting Optune to treat lung cancer, using an array that adheres to the chest.

The website Optune.com also provides a lot of great information and some useful testimonial videos.
