Platelet crash during chemo radiation
Hi everyone. My boyfriend has idh1 mutant grade 4 Astrocytoma. He was undergoing 6 weeks of chemo-radiation. Everything was going well and he hardly had any side effects until week 5 when his platelets dropped to very low levels (19k). They had to stop the chemo. He continued with the radiation and finished it. But he did miss a week of tmz. He is supposed to start 12 rounds of tmz (5/23 cycles) in about a month. We have concerns that he may not be able to tolerate it. Has anyone had a similar experience during the 6 week chemo-radiation period but then moved on to complete the tmz cycles?
