Trying not to beat a dead horse, but as the article you attached says: "however the duration of TKI treatment was an additional predictive factor (p = 0.047; HR 0.93), as shown in other studies." What I'd really like to know is the TFR success rate for those only on 3 years of treatment at entry versus 4 years versus 5 years etc if the data is broken down that way. Dr. Clark mentioned in the conference that 7 years was the "sweet spot", yet my oncologist says it's 5 years and an LLS Webcast I listened to yesterday said 8 years. At just 2 years into treatment, I realize I am jumping the gun, but if waiting longer than 3 years gives me a meaningful advantage for TFR, it would be nice to know this now before committing to extra pre-cessation testing.
As always, thanks - you guys are all the best
