Can a patient receive IMRT while taking target madicine Geftinat? - 1256902

My mom was diagnosed adenocarcinoma of lung stage 2. The lesion is 2.6cm X 2.6cm. Since it is close to her thoracic cavity and she is 80 years old, the doctor did not recommend a surgery. No metastatic. She also had EGFR mutation done and exon 19 showed positive which is good for target medicine(EGFR-TKI).

My mom is in China and all the test were done there too. Now she is receiving IMAR (intensity modulated radiation therapy) and also is taking the target medicine(geftinat) at the same time.She has been treated in hospital for 3 weeks.

My question is: Is my mom's current treatment a right approach? Can she receive IMRT and also take a target medicine at the same time? To be honest, I do not know how mature the technology for cancer treatment in China is and how good and experienced my mom's doctor is. Thanks.

Hello jznj, welcome to Grace. I'm sure you will find the answers you look for here, providing they exist. Unfortunately there are many questions left without straight answers. What I do know about early stage nsclc is that it's curable without surgery. Though I believe the proven research has been with radiation and standard chemo.

I will ask a doctor to respond to your questions. Until then I'd suggest you look through some of these links listed in the link below. Some have to do with the role of EGFR tki's (like gefitinib) for people with non metastatic lung cancer.

This is a long list all the short videos (below are some links picked from this list) http://cancergrace.org/general/2013/02/20/iaslc-vids/

These are from that list and on the subject of early stage cancer and molecular testing. I stopped posting about half way through the list so there may be more.

Here is a list of posts on curable unresectable nsclc. Mostly stage III though your mom fits into the subject if she isn't able to have surgery.

and this is a good place to start in that list,

I hope for all the best for your mom,

Patients who are in the range of 80 are appropriately treated in an individualized way, so there isn't a clear "best" way to approach her care.

In general, we favor local therapy, whether surgery or radiation, for patients with localized disease -- surgery typically being the leading consideration, or radiation in patients who either refuse or aren't great candidates for surgery.

Whether to include gefitinib (Iressa, or gefitinat in some parts of the world) with radiation is a matter of judgment, as there isn't real evidence to speak to this situation. My inclination is to not administer the targeted therapy concurrent with radiation in such a situation, but there's no right or wrong answer here.

Good luck.

Thanks Dr. West. My mom has been treated in a individualized way based on her health condition and the stage of her tumor. She has been doing IMRT radiation theraphy for more that 20 days and taking Geftinat for more 10 days. Her doctor said my mom needs a total of 25 times of IMRT. After that, the doctor will re-evaluate the treatment result. She will only need to take the targeted medicine.After 15th IMRT, my mom was evaluated once by taking CT and was told the size of lesion was reduced. but we do not know exactly whether it is the IMRT or the target medicine that has contributed to the result, maybe both. Hopefully after 25th IMRT, we can see a bigger improment. Jerry

I hope the treatment is successful. Keep a close eye on her or try to have someone close. There isn't any real info about what to expect from these 2 treatments together.
I suppose, though this is purely layman supposition and what I'd do if my husband were in the same position I would watch and act quickly for typical radiation side effects such as esophagitis, pneumonitis explained here, http://www.mayoclinic.com/health/pneumonitis/DS00962
and be proactive with tarceva side effects like rash etc.

The waiting is really difficult but you can't really know the results of radiation because there needs to be about a 3 month period after radiation treatment ends to settle the area down from all the activity. This is a primer on chest radiation. http://cancergrace.org/radiation/2012/03/29/not-black-or-white/#more-14…

All the best,
Janine

P.S. Dr. Sequist responded via email to say when she got to the email Dr. West had responded and she very much agreed with his comments. It's good to have a 2 comments from such exceptional minds even (or is that especially) when they agree with one another.

Thanks Janine. So far my mom's lesion appears to be under control but we will have to keep a close eye on her as you suggested.She was just released from the hospital this past Sunday. The doctor said my mom has received a maximum dose of IMRT and they have seen a big improvement on her treatment and she can stay home and continue to take the targeted madicine. After a month or two, she will need to go back to recheck.
