Abstract

Pulmonary nodules (PNs) develop frequently in patients with acute myeloid leukemia (AML). They are of infectious or inflammatory origin. They pose potential challenges to successful hematopoietic progenitor cell (HPC) transplant as they may be niches for infection reactivation or sites susceptible to subsequent infections. We retrospectively analyzed the outcome of 20 AML patients with multiple PNs who underwent allogeneic HPC transplants (12 related, 8 unrelated). There were 13 males and seven females (median age 52 yrs). Nine patients were in CR1, seven in CR2, and four with residual disease. The median times from appearance of PNs and from last positive CT scans to transplant were three and two months, respectively. The median time from pretransplant CT scans to transplant was one month. Multiple PNs were still reported in 5/20 of the pretransplant scans. The PNs in all five patients did not worsen after transplant. Four patients (one with positive pretransplant CT scan) died within the first 100 d after transplant, but none from primary pulmonary pathology. The median survival of this group of patients was 350 d. Our results, therefore, suggest that multiple PNs of uncertain etiology in patients with AML do not impact adver...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
