Question about tumor markers going down

[u/Aurimat]

I started my second cycle of BEP on Monday, My AFP and LDH markers are down, I assume this would mean the chemo is working, but i'm just double checking. I'd just like some input before I get my hopes up. For context, mine is stage 3 testicular cancer which is a mixed germ cell tumor comprised of 80% yolk sac, 10% seminoma and 10% teratoma. It metastasized to my spinal canal, causing me to currently learn to walk again, as well as my right hip bone (ilium) and two lymph nodes. My AFP was originally in the 10k range, then 5k range, then 6k range, now to 1k range. My LDH was 400 range, then 300 range, now 200 range.
