I have started Tagrisso on Mar. 8 2018, 80mg for 64 days and 40mg for 365 days,
After these days my PET/CT scan has shown progression of 10mm GGO at LLL, color-fading away of one GGO at LLL and another GGO at RLL, on May 24 2018.
On the other hand gene mutation analysis had shown mutation T790M and L858R, at a surgery three years ago.
The 10mm GGO at LLL is in the deeper place of lobe.
My onc. said radio frequency ablation is possible.
Can I expect Tarceva?
What is the next choice?

Hi homeofheart,

Although we can’t give specific advice on your next treatment choice, we can discuss some of the options. It appears that the overall pace of your cancer has been slow. If I read your post correctly, there is only one new or growing GGO, which tends to indicate that Tagrisso has been fairly effective. If there is just a spot or two, then local therapy, as suggested by your oncologist, is a reasonable option, while continuing Tagrisso. Does your doctor suggest continuing Tagrisso?

I would not expect Tarceva to be a leading choice, if you progressed on it previously and if prior mutational testing showed the presence of a T790M mutation. Of course, over time it is possible for your mutational status to have changed, but to find that out you would need a new biopsy.

Other options include standard chemotherapy or immunotherapy. Although immunotherapy tends to have a lower response rate for patients with EGFR mutations, if your PD-L1 expression is high, that might be a viable option. If it’s been quite a while since tissue was collected, that would also require a new biopsy.

Finally, waiting and watching would also be a reasonable option, to see if the GGO grows over time or if other GGOs appear. The current GGO is relatively small and in general the pace of growth of your cancer has been slow, so the risk in delaying new treatment should be small.

I hope that you can have a thorough discussion of your options with your oncologist, and that you can agree on a treatment plan with which you are comfortable.

Hi homeofheart,

Your history is heartening to me since I have a similar condition and hope it can be managed long term while maintaining lung function. Just to add a bit to what Jim wrote, it would be helpful if you could clarify your present situation. I am not entirely sure how many nodules you have of what size and how many are actually growing or are stable. Hopefully you can continue to be managed with Tagrisso and local treatments. If your situation were to progress beyond that then I might look at clinical trials for Exon 20 if they are available where you live.

10/2015 Chest xray found a nodule as part of a physical (no symptoms).
01/2016 Upper left lobe lingula preserving lobectomy stage 2b for 1.9 cm invasive adenocarcinoma with additional 2 mm AIS nodule found in pathology.
03-05/2016 Sixteen weeks of adjuvant cisplatin/vinorelbine.
07/2016 Durvalumab adjuvant clinical trial discontinued after 1st dose knocked out thyroid.
12/2016 Revised to stage 1b (due to VPI) after new guidelines for multifocal lepidic lung cancer.
07/2018 Next scan.

Hi JimC
Thank you for your thoughtful and kind advice.  
Probably I can argue about an option of the treatment with my oncologist.

Hi onthemark
I like to know size, number, growing rate, mixed status of mutation, classification of adeno-carcinoma.
Thank you for your advice.
