Conversely, compared having a slower developing tumor. did not impact PFS as the tumor dynamics have been comparable involving the two instances and mainly because PFS was a relative measurement from the start out of your therapy.

The variations in the tumor proliferation rate possess the largest effect on PFS and OS.Determined by the results in the sensitivity study, which demonstrated that tumor proliferation was by far the most vital factor influencing PFS and OS, we examined the impact of low, medium, and high tumor proliferation prices on PFS and OS as a function in the time of TRT injection following CAR-T cell therapy (Figure 7).
