Yup.
Maybe the anecdotal successes here in the forum are "hits" from a hit or miss approach.
I guess no matter the intensity of approach, determining beforehand which agents have the best chance of working would be ideal.
Tests like Rational therapeutics, upcoming DRIT and the new mathematical model (
http://www.medicalnewstoday.com/articles/150667.php) might be helpful if more embraced. The mathematical model claims to predict cancer stem cell eradication too. Even if not a "positive" test, narrowing the field of candidates would seem to increase the chance of picking something helpful.
Maybe not just one of the tests either. Assuming they all have potential inaccuracies, a
pattern of results could really give merit to a treatment choice.
Me thinks, determining what would work and delivering it in a user-friendly metronomic fashion would be a huge step forward.
