Thus, treated MM patients who were persistently CTPC-negative in blood (i.e., CTPC −/−) or turned negative after a first positive result (i.e., CTPC +/−), had significantly superior progression free survival rates at two years (92.5%) compared to cases with positivity for CTPC in the last NGF analyses (CTPC −/+ or CTPC +/+ cases) (41%) [35]. The gene discussed is NGF; the disease is Miyoshi myopathy.
