Yolk Sac Ovarian Tumor

AoA. My mother has been diagnosed with yolk sac ovarian tumor. CA125=325, AFP=1100,with pleural effusion and size was about 14*12*8. Dctrs said jts 4th stage. After 3 cycles of BEP chemo at NORI AFP=55 and tumor size has been decreased. But after every cycle of chemo she developed severe pancytopenia. She is also having a acute problem of eating and digesting food. Running on fresh juices and yakhni etc.Now same happened after 4th cycle though doctors removed Bleomycin in this cycle but same happened with Wbc=0.4 & platelets=6000. She didn’t had bleeding. we are having transfusion now. What you doctors suggest now. Need it.
