Does anyone have the Lustre trial protocol?

some might argue some of the constraints are a little aggressive

Nice prez

It's interesting tho in the thing they say

In then their plan

I'm like "that 30 Gy looks a little juicy"

And then sure 'nuff:

With a little more inhomo they could've made the plan a little bit better right @elementaryschooleconomics and @RickyScott ... this is the kind of homogeneity I would accept in a whole breast plan lol

They even made it explicit

The post from Swaminath on mednet said the 60/15 was meant to be more like a standard fractionated approach, so they mandated ~110% hotspots. He's just thinking about us poor americans. Can't do stereo for > 5 fractions.

I like this slide from this year's Lung Spring Refresher:

But yeah, agree with @evilbooyaa:

Thanks! I was looking for the lung constraint. I missed it at the bottom of that mednet thread.

These are similar to my constraints for definitive early stage dz… point max of bronchus <100 EQD2

NRGLU004 also has 60/15 constraints. SUNSET trial also has 60/15 constraints.

Pay for a fractionated stereo case is pretty similar to 15 fraction IMRT/IGRT. So 5 fractions, 15 fractions... Both ok to me. You can create a stereo plan and just call it 15 fraction IMRT/IGRT.


6 fractions?! GTFO

6 is pissing on American flag

6-8

6-8

8 at least you get a “dangling” OTV

 

[jondunn]

8 is great.

6-7 not great, bob!

-7 Gy x 10 for big, but not so bad.
-5 Gy x15 for big, bad and ugly (at least to the parts that aren’t touching something important)
