Stem cell transplantation during cancer

Abstract

Hematological malignancies account for approximately 9.5% of new cancers diagnosed annually. Lymphoma is the most frequent of all known categories of hematological malignancies. Worldwide, extensive research has focused on this type of cancer. However, new treatments are investigated in various clinical as well as pre-clinical studies. Hematopoietic stem cell transplantation (HSCT) is a recent and upcoming treatment strategy for patients with hematopoietic malignancies and inborn errors of metabolism or immune deficiencies. Recent studies have revealed that successful clinical outcome of this treatment strategy depends on multiple factors including the protocol applied, disease under treatment, health of the patient, source of the grafts, severity of complications such as graft versus host disease during grafting and associated infections. The scope of this review is to achieve greater understanding of various clinical effects of the disease and related mechanisms. The electronic database Pubmed was searched for pre-clinical as well as clinical controlled trials reporting efficacy of the HSCT against hematological malignancies.
