About

The traditional way of doing a donor transplant is to give high doses of chemotherapy and radiation before giving the stem cells. However, high doses of chemotherapy and radiation can have serious side-effects. The doctors think that the transplant will be safer and more likely to be successful with reduced doses of chemotherapy and radiation. The purpose of this study is to find out how good a combination of chemotherapy and radiation at reduced doses followed by a cord blood transplant are at treating cancer.

The stem cells chosen for the transplant are from umbilical cord blood. Umbilical cord blood is collected from healthy newborn babies and frozen. One cord blood collection is called a "cord blood unit." On transplant day, the cord blood will be given through the catheter just like a blood transfusion. Transplants done this way have been successful. However, this type of transplant is fairly new. Therefore, it is important to study it so the doctors can better understand how it works.

Most blood or bone marrow transplants using donor stem cells are done as part of a study. When patients are on a study we test new ways of treating them which we think may be better than the old ways. We collect information about the result of this treatment so we can understand how well the treatment works. This is so we can learn better ways to treat our patients.

• Receipt of at least one cycle of cytotoxic chemotherapy, azacitidine or decitabine.
• MDS patients must have < or = to 5% bone marrow myeloblasts and ANC > or = to 0.2 (growth factor supported if necessary) at transplant work-up.

• Eligible patients with transformed indolent NHL/CLL will:

have CR/PR of the large cell component of their disease after either salvage chemotherapy or an autologous transplant.

• Eligible patients with mantle cell NHL will:

be high-risk as such as p53 positivity and be in 1st CR/PR after initial therapy OR have relapsed disease following initial therapy and be in 2nd or 3rd CR/PR after salvage chemotherapy.

• Eligible patients with indolent B cell NHL (such as, but not limited to, follicular, small cell or marginal zone NHL) or CLL will have 2nd or subsequent progression (pre-allograft cytoreduction necessary but CR/PR not required).
• Eligible patients with HL will be without progression of disease (POD) after salvage chemotherapy.

Experimental group

Description:

There are three chemotherapy drugs involved. They are called fludarabine (5 doses), cyclophosphamide (1 dose), and thiotepa (2 doses). Also two days of radiation therapy. This is called Total Body Irradiation or TBI. The TBI if given for two days before, the transplant. On transplant day, the cord blood cells will be given through a catheter. The immune suppressing drugs given are called cyclosporine-A (CSA) and mycophenolate mofetil (MMF). These will be started 3 days before the transplant and will be given through the catheter. Later they can be given as tablets.

Treatment:

Drug: fludarabine, cyclophosphamide, thiotepa, radiation therapy, unrelated donor umbilical cord blood graft
