Welcome to Connect, @jda28 though I wish it were under less stressful circumstances. Your daughter is on quite a medical journey with Mantle Cell Lymphoma at such a young age. Being a mom myself, I know how that occupies your thoughts.

There is a discussion in the forum with other members who also have been diagnosised with MCL. I posted the link for you. It is a dated discussion but you can reverse the order to read the more current replies.

From my understanding, Calquence (Acalabrutinib) is one of the targeted first line treatments for MCL and other forms of Lymphoma such as CLL. This may help bring her into remission so that she can receive CAR-T cell therapy.

CAR-T has been gaining so much ground over the past years with the advancement in treating diseases such as MCL.
Of course there’s another support group for CAR-T. ☺️ You may want to peruse through the conversations with members such as @4health4bonnie kirkwilliams2049 @anthea29 and others who recently had the CAR-T for their blood conditions. The link is below:

Has your daughter had a good response to the Calquence?
