Twice in the last week, I have been in contact with people whose current treatment is no longer effective. This is a critical decision point. The options seem to be:
1) Get a second opinion; or
2) Find a clinical trial that matches your specific needs.
Last week I listed my favorite blogs. On one of them, https://www.inspire.com, I found a link to a website where you can match your particular cancer (lung and all other cancers) and your specific circumstances to the entire pool of clinical trials. Here is the resource:
It's not perfect, but it does narrow the field a bit. It may even be useful to print out the list of possible clinical trials and bring them with you to your next appointment with your oncologist for discussion.
I hope you find this useful.
